Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a lens layout setting apparatus for lens grinding process and display apparatus for the same to display a disposition of optical axis of a lens in a eyeglass lens shape and a layout of the shape of a cross section of the lens when processing data for the eye glass lens are calculated based on data of eyeglass lens shape (data of lens shape) for a eyeglass frame, or when a lens to be processed (unmachined lens) is ground into an eyeglass lens shape based on the data of eyeglass lens shape.

2. Description of the Prior Art

As a lens layout display apparatus for lens grinding process, for example, there has been known an apparatus disclosed in Japanese Utility Laid Open patent Hei 5-39855.

This lens layout display apparatus comprises an input menu area to display data for grinding as a plurality of input menu, a switching block having a plurality of selection switches arranged in accordance with the input menu to select the lens grinding data, and a page changeover switch.

As for a data input screen of the lens layout display apparatus, a flat display device such as a liquid crystal display is employed. When a set of lens grinding data has been input through the input menu and the switching portion of this kind of lens layout display apparatus, prescribed lens grinding data is output from the lens layout display apparatus. The lens grinding data which has been output is fed to a lens grinding mechanism of a lens grinding apparatus through an interface, then a lens grinding process is performed by the lens grinding apparatus.

In the lens layout display apparatus of a lens grinding apparatus having the aforementioned configuration, a routine for lens grinding process is not started unless input of the lens grinding data is completed. Accordingly, while an edge shape or edge thickness of an eyeglass is being measured, it is impossible to display another eyeglass lens shape data for an eyeglass frame required for lens grinding process for other lens or to perform adjustment of layout. As a result, in the above described prior lens grinding apparatus, it is impossible to improve the efficiency of lens grinding process for eyeglass lens or to perform data processing in user friendly manner.

Moreover, in the conventional lens layout display apparatus of the lens grinding apparatus, an operator cannot change a displaying order of specified items according as his preference, or to add/delete or to exchange an item itself.

This requires a complicated work procedure and a long time from a data input to a data setting, disabling smooth operation.

Moreover, in the conventional lens layout display apparatus of the lens grinding apparatus, since the data input format for lens grinding process is determined beforehand, it is troublesome and time-taking time to input data according to a kind of lenses such as a single vision lens and a progressive-multi-focus lens.

In addition to it, it is preferable that position for a V-shaped protrusion at the lens edge surface can be easily accomplished even in case of different kind of eyeglass lenses. However, there has been no methods suitable for data input of V-shaped protrusion at edge surface processing or method suitable for data calculation of V-shaped protrusion at edge surface processing. In this situation, conventionally, an operator should repeat simulation of V-shaped protrusion so as to suitably settle the position of V-shaped protrusion at the edge surface and adjust the data for processing the V-shaped protrusion. This procedure of settlement and adjustment is troublesome and time-taking.

To solve the above described problems, it is preferable to improve the processing efficiency of lens grinding process by improving display used for setting adjustment, thereby enabling to realize a format free data processing.

The processing room 4 has a structure with a deep bottom and includes a portion 512 which is parallel to an inner wall (a vertical wall) as shown in left side of FIG. 8 A and includes a portion 511 which is gently slanted from the front side to the back side, and each portions 511 , 512 have steps respectively. A bent portion 513 is formed on the portion 511 , and slanted surfaces 511 a , 511 b are made to form the bent portion which are opened toward the cover 5 . Herein an angle of the slanted surface 511 b is arranged to be larger than that of the slanted surface 511 a.

A car ridge which is not shown in the drawings is disposed at a back side of the processing room 4 , and arm portions (not shown) of the car ridge are also disposed respectively at the outside of the left and right side walls (not shown) which form the processing room 4 . And the car ridge is made rotatably around a supporting axis (not shown) whose back end portions are extending in left and right direction, and the arm portions are made swingably in vertical direction. Herein the car ridge is arranged to be able to reciprocate in the left and right direction. As for supporting structure of the car ridge of this kind a well know structure can be selected from the prior art, since, the detailed explanation is omitted here.

A pair of lens rotating shafts 501 , 501 which extends in the left and right direction, are disposed in the processing room 4 . One of the lens rotating shafts 501 , 501 is held rotatably and at the same time fixedly along the shaft axis direction by one of the arm portion of the car ridge, and another one of the lens rotating shafts 501 , 501 is held rotatably and at the same time movably for adjustment along the shaft axis direction by another one of the arm portion of the car ridge. A well known structure also can be applicable to this kind of holding structure for the lens rotating shafts 501 , 501 on the car ridge, the detailed explanation is omitted, too.

An unmachined raw material lens with rounded shape (unmachined eyeglass lens i.e. lens to be processed) 502 is held by the one pair of lens rotating shaft 501 , 501 which are disposed in the left and right. A grinding stone 503 and a grinding stone shaft 504 which holds the grinding stone 503 , are disposed obliquely under the lens rotating shaft 501 . This grinding stone shaft 504 is arranged to be driven for rotation by a driving motor which is not shown in the drawings.

The grinding stone has a set of grinding stone such as a rough grinding stone 503 a , a V shape grinding stone 503 b with V-shaped groove for V shape portion processing, and a mirror finishing grinding stone 503 c . In front of the grinding stone 503 , a cover 505 is disposed.

Further, a rotating arm 510 is disposed in the opposing left side portion of the processing room 4 . This rotating arm 510 is arranged rotatably (swingably) in vertical direction with its lower end portion as a center, and at the same time it is arranged to be rotated in vertical direction by a pulse motor for the arm rotation. Also a rotating shaft 508 is rotatably held by the top end portion (upper end portion) of the rotating arm 510 as shown in FIG. 8A , 8 ( b ) This rotating shaft 508 is driven to rotate by another pulse motor for shaft rotation which is not shown in the drawings. Further a chamfering grinding stone 506 , 507 are attached to this rotating shaft 508 , and at the same time a cutter for grooving (grooving grinding stone) 520 is also attached as well.

Herein, the chamfering grinding stone 506 , 507 are covered with a cover 509 to prevent from the operator touching with it erroneously. A hose (not shown) is disposed to supply cooling water onto a surface of the grinding stone 503 .

For a grinding process of the eyeglass lens from the raw material lens 502 to a specified lens shape (lens shape of an. eyeglass frame) utilizing this kind of grinding stone 503 , firstly the lens shape data (θi, ρi) of an eyeglass frame, eyeglass lens (model lens) or a template are measured by the eyeglass frame shape measuring apparatus 1 , and the resulted lens shape data. (θi, ρi) are input to the lens grinding processing apparatus 2 .

Secondly, after the lens grinding processing apparatus 2 has received the lens shape data (θi, ρi), the apparatus makes the car ridge which is not shown in the drawings turn in vertical direction and controls it based on the lens shape data (θi, ρi), and it roughly grinds the raw material lens 502 into an eyeglass lens with a shape of the specified eyeglass frame by the rough grinding stone 503 a through a rotation and a controlling of the lens rotating shaft 501 , 501 and the raw material lens 502 with a combined rotation and controlling of the car ridge in the vertical direction.

And, at an edge portion of the roughly ground eyeglass lens, V-shaped protrusion by which the ground eyeglass lens is fixed into the frame of the eyeglass, and a wiring grooving for a wire by which the eyeglass lens is held in the frame of the eyeglass, are formed. When the V-shaped protrusion to fix the eyeglass lens into the frame of the eyeglass is formed at the edge portion of the eyeglass lens, the lens grinding processing apparatus 2 further grinds the eyeglass lens ML which has been ground in the specified shape for the lens shape of an eyeglass frame based on the lens shape data (θi, ρi) by the V-shaped protrusion grinding stone 503 b shown in FIG. 8B to form the V-shaped protrusion at the edge portion (lens peripheral portion) of the eyeglass lens ML, and after the V-shaped protrusion has been formed, the lens grinding processing apparatus 2 makes the edge portion of the eyeglass lens to be formed chamfering by the chamfering grindstone 506 , 507 which are shown in FIG. 8 B. Further, when the wiring grooving for the wire by which the eyeglass lens is held in the frame of the eyeglass, is formed at the peripheral portion of the eyeglass lens, the lens grinding processing apparatus 2 grinds the eyeglass lens ML which has been ground in the specified shape for the lens shape of an eyeglass frame based on the lens shape data (θi, ρi) by the grooving cutter 520 shown in FIG. 8B to form the wiring groove at the edge portion (lens peripheral portion) of the eyeglass lens ML, and after the wiring groove has been formed, the lens grinding processing apparatus 2 makes the edge portion of the eyeglass lens to be formed chamfering by the chamfering grindstone 506 , 507 which are shown in FIG. 8 B.

<Edge Thickness Measuring Apparatus>

For the edge thickness measuring means which is arranged to be able to enter into and get out of the processing room 4 , there may be used those of well known in the prior art. For example, there may be an edge thickness measuring means composed by that a pair of feelers which are arranged to be able to enter into and get out of the processing room 4 by a driving motor such as a pulse motor, are disposed in the processing room 4 while the lens to be ground is held between the above described lens rotating shafts, and the distance between these feelers are detected as an edge thickness value. In this edge thickness measuring means with the above described composition, the lens thickness Wi corresponding to a point (θi, ρi) of the lens is measured by means that the top end portions of the feelers which are made into the processing room 4 are arranged to abut with a front refracting surface and a back refracting surface of the lens to be ground, and at the same time the driving motors which drive the pair of lens rotating shafts are operated and controlled in accordance with the angle θi based on the lens shape data (θi, ρi), and the driving motors for driving the pair of lens rotating shafts are operated and controlled based on the lens shape data (θi, ρi), and the abutment point of the feelers on the lens to be ground is moved to corresponding to the point of ρi on the lens to be ground, since, the thickness Wi is thought to be the edge thickness corresponding to the lens shape data (θi, ρi).

(Operating Panel 6 )

The control panel 6 has “Clamp” switch 6 a to clamp the eyeglass lens by the lens rotating shafts, “Left” switch 6 b and “Right” switch 6 c to designate which side of the eyeglass lens is processed or to change which side of the eyeglass lens is displayed, “Grinding stone movement” switches 6 d , 6 e to move the grinding stone in left and right direction, “Re-finishing/Test” switches 6 f to process again when a state of the finished eyeglass lens is not enough or to grind as a testing, “Lens rotating” switch 6 g for a lens rotating mode and “Stop” switch 6 h to stop the lens processing operation as shown in FIG. 10 A.

By this arrangement of disposition of all switches to be required for the actual lens processing operation, a load to the operator can be reduced.

<Operating Panel 7 >

(Operating panel 7 )

As described above, the control panel 7 and the liquid crystal display device 8 composes the function setting means in combination as a whole. However, in this specification, only the operating panel 7 may solely be called as a function setting means. This is because the function keys F 1 -F 6 are all made in the control panel 7 as described above. These function keys F 1 -F 6 are arranged at the lower portion of the liquid crystal display device 8 to be used for setting various functions and for achievement of them. In this context, it can be called that these function keys F 1 -F 6 are the function setting means which are merely one part of the control panel 7 . In addition to it, other switches (which will be explained later) which are other part of the control panel 7 , may be also called the function setting means. Hereinafter the concrete function of these function keys F 1 -F 6 and the function of the other various kind oF keyes will be explained.

This control panel (function setting means) 7 has “Screen” switch 7 a , “Memory” switch 7 b , “Data demand” switch 7 c , “−, +” switch with seesaw mechanism 7 d and “∇” switch 7 e as shown in FIG. 10 B. All of these switches 7 a , 7 b , 7 c , 7 d and 7 e are disposed in a side portion of the liquid crystal display device 8 .

Herein, the above described “Screen” switch 7 a is used to change a display state of the liquid crystal display 8 , and the “Memory” switch 7 b is used to memorize a setting condition about the grinding process into memory. Also, the “Data demand” switch 7 c is used to get the lens shape data (θi, ρi), and the “−, +” switch 7 d with seesaw mechanism is used to adjust a value of input data and so on. It may also be suitable that “−” and “+” switches of this “−, +” switch 7 d are separately disposed.

The “∇” switch 7 e is used to operate and move a indicator pointer P, PE 1 , PE 2 , PE 3 and so on which will be explained later, when various setting which are required for data processing, are achieved.

For example, this “∇” switch 7 e can be used as a selecting means for eyeglass lens. That is to say, “∇” switch 7 e is used when one of a kind of the eyeglass lens is selected to locate the indicator pointer PE 2 on the items such as within “Single vision”, “Ophthalmological prescription”, “Progressive”, “Bifocal”, “lenticular” and “Tsubokuri” which show various kinds of eyeglass lens.

At the same time, the control panel 7 has function keys F 1 -F 6 which are disposed in the lower portion of the liquid crystal display device 8 . These function keys F 1 -F 6 are used when a setting about the grinding process of the eyeglass lens is achieved. That is to say, these function keys F 1 -F 6 are used as a function setting means to achieve various setting which are required for data processing about the grinding process of the eyeglass lens. For the examples of these kind of data, there are lens shape data for the eyeglass frame of an eyeglass or an rimless frame of an eyeglass, lens shape processing data to grind the raw material lens based on this lens shape data and so on.

Moreover, in addition that the function keys F 1 -F 6 are used when setting about the grinding process for an eyeglass lens, they are used for responding and selection to various message which are displayed during the grinding process on the liquid crystal display device 8 .

Among these function keys F 1 -F 6 , the function key F 1 is used to input the kind of lens, the function key F 2 is used to input the course of processing, the function key F 3 is used to input a kind of lens material, the function key F 4 is used to input a kind of eyeglass frame, the function key F 5 is used to input a kind of chamfering process and the function key F 6 is used to input a mirror finishing process at the setting of grinding process (screen for layout) as shown in FIG. 11 .

As for the kind of lenses which are input by the function key F 1 , there are “Single vision”, “Ophthalmological prescription”, “Progressive”, “Bifocal”, “Lenticular”, “Tsubokuri” and so on. Herein the “Lenticular” generally means a lens of plus with much degree of refracting, and “Tsubokuri” generally means a lens of minus with much degree of refracting in the optician's industry.

As for the course of processing which are input by the function key F 2 , there are “Auto”, “Try”, “Monitor”, “Change of frame” and so on.

As for the kind of lens material which are input by the function key F 3 , there are “Flat”, “High index”, “Glass”, “Polycarbonate”, “Acrylic” and so on.

As for the kind of eyeglass frame which are input by the function key F 4 , there are “Metal”, “Celluloid”, “Optil”, “Flat”, “Grooving (thin)”, “Grooving (middle)”, “Grooving (thick)” and so on.

As for the kind of chamfering process which are input by the function key F 5 , there are “None”, “Small”, “Middle”, “Large”, “Special” and so on.

As for the mirror finishing which are input by the function key F 6 , there are “None”, “Applicable”, “Mirror finishing at the chamfering portion” and so on.

Herein, the above described mode, kind and order of the function keys F 1 -F 6 are no need to be restricted as the embodiment. Further, the number of the function keys is also no need to be restricted as the embodiment, for example, it may be suitable to dispose another function keys to select such as “Layout”, “On processing”, “Process finished”, “Menu” and so on for selection of tubs TB 1 -TB 4 which will be explained later.

<Control Circuit (Control Means)>

The lens grinding processing apparatus 2 has a control circuit (control means) 30 as shown in FIG. 64 . This control circuit 30 has a first calculation control circuit (first calculation control means) 31 which includes a first CPU (CPU-1) and at the same time it has a second calculation control circuit (second calculation control means) 32 which includes a second CPU (CPU-2) and which is connected to the first calculation control circuit 31 .

The first calculation control circuit 31 is used to read data from a memory and to control the setting of a layout for lens grinding process when the edge thickness is measured and when the lens is ground for processing. And the second calculation control circuit 32 is used to control the continued steps of lens grinding process based on the layout information processing condition), such as rough grinding of the lens to be processed, V-shaped protrusion processing, finishing process and so on after the edge thickness of lens has been measured.

To the first calculation control circuit 31 there is connected the liquid crystal display device 8 and a setting data memory 33 to store the data which are set by the eyeglass frame shape measuring apparatus 1 , each of keyes 6 a - 6 n on the control panel 6 and the function keys F 1 -F 6 .

To the second calculation control circuit 32 there is connected the processing data memory 34 to store the data during the grinding process, a control circuit 35 to control and drive the each driving motors of the grinding processing apparatus and a distance measuring means 36 of the edge thickness measuring means.

The operating signal of the function keys F 1 -F 6 are input to the first calculation control circuit 31 . The first calculation control circuit 31 achieves to change a part or all of the displayed screen on the liquid crystal display device 8 , to change the mode of process or to complete the task by means of pushing a selected function key from F 1 -F 6 which corresponds to the function displayed portion H 1 -H 6 on the liquid crystal display device 8 , in accordance with the designated display which corresponds to the selected function key F 1 -F 6 . Also the first calculation control circuit 31 controls a display state of a state display area E 4 on the liquid crystal display device 8 .

[Operation]

In the following, a display onto a liquid crystal display device 8 by the arithmetic control circuits 31 , 32 constituted as described above will be explained.

(1) Initial Display of the Liquid Crystal Display Device 8 , and So On

On the upper edge of the liquid crystal display device 8 are provided display parts such as “Layout” tab TB 1 , “Processing” tab TB 2 , “Processed” tab TB 3 , and “Menu” tab TB 4 . On the “Processing” tab TB 2 portion are provided a plurality of indicator (cursor) C 1 -C 12 for displaying process progressing circumstances of a right eye-lens and a plurality of indicators (indicators) C 1 -C 12 for displaying process progressing circumstances of a left eye-lens in a vertically corresponding manner. The indicators (indicators) C 1 -C 12 are used to display the processing state.

Further, on the lower edge of the liquid crystal display device 8 are provided function display parts H 1 -H 6 corresponding to function keys F 1 -F 6 .

The liquid crystal display device 8 selects the tab TB 1 to switch a display to the “Layout” display, selects the tab TB 2 to switch a display to the “Processing” display, selects the tab TB 3 to switch a display to the “Processed” display, and selects the tab TB 4 to switch a display to the “Menu” display.

Colors of these tabs TB 1 -TB 4 are set to independent different colors. Moreover, the circumferential background except areas E 1 -E 4 described later is also switched to background color which is the same color as the tabs TB 1 -TB 4 simultaneously with the switching of selection of the tabs TB 1 -TB 4 .

For example, the “Layout” tab TB 1 and the whole display screen (background) marked with the tab TB 1 is displayed in blue, and the “Processing” tab TB 2 and the whole display screen (background) marked with the tab TB 2 is displayed in green. Further, the “Processed” tab TB 3 and the whole display screen (background) marked with the tab TB 3 is displayed in red, and the “Menu” tab TB 4 and the whole display screen (background) marked with the tab TB 4 is displayed in yellow.

As described above, since the tab TB 1 -tab TB 4 separated in color by work and the circumferential background are displayed in the same color, the worker is able to recognize or confirm easily what work is now doing.

Further, operating contents selected for operation by the function keys F 1 -F 6 such operating contents as screen switching, and mode selection are displayed suitably as necessary on the function display parts H 1 -H 6 . However, in an undisplay state at which the operating contents are not displayed on the function display parts H 1 -H 6 , a pattern, a numerical value or a state different from those corresponding to the functions of the function keys F 1 -F 6 can be displayed on the function display parts H 1 -H 6 .

Further, when the function keys F 1 -F 6 are operated, that is, when either key of the function keys F 1 -F 6 is depressed, a display of a mode or the like may be switched every time either one of the function keys F 1 -F 6 is depressed. For example, when the function key F 1 is operated, a display of a mode or the like may be switched every time the function key F 1 is depressed.

Further, it is also possible that when the function keys F 1 -F 6 are depressed, a list of modes corresponding to the function keys F 1 -F 6 is displayed (a pop-up display) to enable the selection operation. It is also possible that for example, when the function key F 1 is operated, a list of modes corresponding to the function key F 1 is displayed (a pop-up display) to enable the selection operation, as shown in FIG. 12 . The list in the pop-up display is displayed by a letter, a pattern or an icon or the like.

Further, when either of “Layout” tab TB 1 , “Processing” tab TB 2 , or “Processed” tab TB 3 is selected, an icon display area E 1 , a message display are E 2 , a numerical value display area E 3 , and a state display area E 4 are divisionally displayed.

Further, in the state that selected the “Menu” tab TB 4 , a user using mode of FIG. 13 or a service-man using mode of FIG. 14 is displayed as a menu display area E 5 . Alternatively, in the state that selected the “Layout” tab TB 1 , the “Processing” tab TB 2 and “Processed” tab TB 3 are not displayed but when the layout setting is completed, the “Processing” tab TB 2 and “Processed” tab TB 3 may be displayed.

That is, in the state that selected the “Menu” tab TB 4 , first, the “Menu” of the user using mode as shown in FIG. 13 is displayed on the left side of the menu display area E 5 , a letter ‘Execution’ corresponding to the function key F 1 is displayed at the left bottom of the menu display area E 5 , and a letter ‘Repairman’ corresponding to the function key F 6 is displayed at the right bottom of the menu display area E 5 . One out of the menu is selected and the F 1 is depressed, then the selected menu can be executed. Further, by depressing the F 6 , the user using mode shown in FIG. 13 is switched to the menu screen of the service man, i.e., the repairman using mode shown in FIG. 14 . Also in this case, the letter ‘Execution’ corresponding to the function key F 1 is displayed at the left bottom of the menu display area E 5 . However, at the right bottom of the menu display area E 5 is displayed a letter the letter ‘User’ instead of a letter the letter ‘Repairman’. In this state, when the F 6 is depressed, the menu screen of the repairman using mode shown in FIG. 14 is switched to the user using mode shown in FIGS. 13 and 14 .

Further, in the state that selected the “Menu” tab TB 4 , matters set from the menu display area E 5 become a detailed menu display area E 6 , as shown in FIGS. 15-26 , and setting of the detailed menu is carried out. It is noted that a detailed menu display shown in FIG. 16 may be employed in place of the menu display shown in FIG. 13 . Next, a description will be made of a case where the ‘Setting’ is selected.

Further, a letter of “Down” is displayed on function display parts H 1 , H 3 , and H 5 corresponding to the function keys F 1 , F 2 and F 3 , and a letter of “Execution” is displayed on a function display part H 6 corresponding to a function key F 6 .

On the first detail display area E 62 are displayed items of “Setting”, “Adjustment”, and “Maintenance”, and a cursor-type pointer PE 1 for inverting a background color and a letter color every time the function key F 1 is depressed. Every time the function key F 1 is depressed, the cursor-type pointer PE 1 is moved in order of “Setting”, “Adjustment”, and “Maintenance” to invert and display a background color and a letter color of the moved position. In this manner, either of “Setting”, “Adjustment”, or “Maintenance” is selected and designated by the cursor-type pointer PE 1 . Thereafter, a selection (designation) item is decided by operation of the function key F 6 corresponding to “Execution” of the function key display part H 6 .

When “Setting” is selected in the first detail display area E 62 as described above, the second detail display area E 63 is displayed. On the second detail display area E 63 are displayed “Setting changing mode”, “Clamp pressure setting mode”, and “Communication port setting mode”, and a cursor-type pointer PE 2 for inverting a background color and a letter color every time the function key F 3 is depressed. Every time the function key F 3 is depressed, the cursor-type pointer PE 2 is moved in order of “Setting changing mode”, “Clamp pressure setting mode”, and “Communication port setting mode” to invert and display a background color and a letter color of the moved position. In this manner, either of “Setting changing mode”, “Clamp pressure setting mode”, or “Communication port setting mode” is selected and designated by the cursor-type pointer PE 2 . Thereafter, a selection (designation) item is decided by operation of the function key F 6 corresponding to “Execution” of the function key display part H 6 .

When “Setting changing mode” is selected in the second detail display area E 63 as described above, a third detail display area E 64 is displayed. On the third detail display area E 64 are displayed items of “Setting of language”, “Initial setting of F key (function switch)”, “Setting of pop-up display”, “Setting of layout initial value”, “Setting of display screen”, “Setting of adsorption mode”, “Setting of size” and, “Contrast adjustment of screen”, and a cursor-type pointer PE 3 for inverting a background color and a letter color every time the function key F 3 is depressed. Every time the function key F 5 is depressed, the cursor-type pointer PE 3 is moved in order of “Setting of language”, “Initial setting of F key (function switch)”, “Setting of pop-up display”, “Setting of layout initial value”, “Setting of display screen”, “Setting of adsorption mode”, “Setting of size” and, “Contrast adjustment of screen” to invert and display a background color and a letter color at the moved position. In this manner, “Setting of language”, “Initial setting of F key (function switch)”, “Setting of pop-up display”, “Setting of layout initial value”, “Setting of display screen”, “Setting of adsorption mode”, “Setting of size” or, “Contrast adjustment of screen” is selected and designated by the cursor-type pointer PE 3 . Thereafter, a selection (designation) item is decided by operation of the function key F 6 corresponding to “Execution” of the function key display part H 6 .

In FIGS. 17 , 19 , and 21 , a letter of “Down” is displayed on the function display part H 5 similar to FIG. 15 , and In FIGS. 17 , 19 , 21 , 23 and 25 , a letter of “Execution” is displayed on the function display part H 6 similar to FIG. 15 . Further, a letter of “Execution” is displayed on the function display part H 5 in FIGS. 18 , 20 , 22 , 24 and 26 , and a letter of “Return” is displayed on the function display part H 6 .

Further, the operation for selecting the cursor-type pointers PE 1 -PE 3 by operation of the function keys F 1 , F 3 and F 5 to execute them by the function key F 6 or the like is similar thereafter and is sometimes omitted.

<Setting of Language>

The cursor-type pointer PE 3 of the third detail display area E 64 shown in FIG. 15 is adjusted to “Setting of language” and selected (designated), and afterwards the function key F 6 is depressed for execution, then a display of the detail menu display area E 6 is switched as shown in FIG. 16 . On the first detail display area E 62 are displayed items with regard to languages (or country names) such as “Dutch”, “English”, “German”, “Spanish”, “Japanese”, and “Chinese”. Further, in FIG. 16 , a letter of “Execution” is displayed on the function display part H 5 , and a letter of “Return” is displayed on the function display part H 6 .

For example, in a case where the present setting of FIG. 16 is “Japanese”, when the cursor-type pointer PE 3 is adjusted to “English” and selected (designated) of the first detail display area E 62 and the function key F 5 is depressed for execution (decision), switching of a message language is carried out so that languages displayed after next starting are switched to English. Country language messages are prepared by languages in accordance with a predetermined format. A user message such as an alarm message out of messages necessary corresponding to country messages is described, as a unit of one message, using characters such as a symbol, a letter, a Figure or the like that can be identified individually ever message. Thereby, in setting languages in the conventional lens grinding processing apparatus, work for switching corresponding to country languages is simplified to improve the working efficiency.

<Initial Setting of F Key>

The initial setting of F key is for the function keys F 1 -F 6 in the control of lens grinding processing. By the initial setting of F key, a display of the function display parts H 1 -H 6 is made as shown in FIGS. 34-43 , FIGS. 48 , 53 , and 57 .

The initial setting of F key is started by adjusting the cursor-type pointer PE 3 of the third detail display area E 64 shown in FIG. 15 to “Initial setting of F key” to select (designate), after which the function key F 6 is depressed to execute (decide) “Initial setting of F key”. Thereby, items of “Lens type”, “Course”, “Lens”, “Frame”, “Chamfer”, “Mirror face”, and “Beep sound” are displayed on the first detail display area E 62 as shown in FIG. 18 .

With this, on the second detail display area E 63 are displayed set contents such as “Lens type”, “Course”, “Lens”, “Frame”, “Chamfer”, “Mirror face”, and “Beep sound” before setting changing as shown in FIG. 18 . That is, in a case where as the set contents before setting changing, for example, “Lens type”, “Course”, “Lens”, “Frame”, “Chamfer”, “Mirror face”, and “Beep sound” are set to “Single vision”, “Auto”, “Nothing”, “Metal”, “Nothing”, “Nothing”, and “Nothing”, respectively, “Single vision”, “Auto”, “Nothing”, “Metal”, “Nothing”, “Nothing”, and “Nothing” are displayed in that order on the second detail display area E 63 .

Here, for example, in a case where in the second detail display area E 63 , “Single vision” is changed in setting to “Progressive”, the indicator PE 2 is adjusted to “Single vision”. Thereby, the third detail display area E 64 shown in FIG. 18 is displayed right next to the second detail display area E 63 . Moreover, on the third detail display area E 64 are displayed items such as “Eye prescription”, “Progressive”, “Bifocal”, “lenticular”, “Tsubokuri”, “EX”, “Strong minus”, and “Strong minus”.

Accordingly, “Lens type” is changed insetting to “Progressive” lens by the cursor-type pointer PE 3 is adjusted to the item of “Progressive” that desired to be selected out of the items displayed in the third detail display area E 64 to select “Progressive” after which the function key F 5 is depressed for execution.

Here, the “EX” lens is a lens which is different in thickness of a lens edge (for example, a lens edge thickness of a lower half of an eye-lens is thin) in a predetermined area of a refractive surface; the “Strong minus” is a lens, which is one kind of Tsubokuri, in which a lens edge end of a rear refractive surface of a minus lens whose refractive degree is large (thick in an edge surface) is chamfered obliquely; and the “Strong minus” is a lens, which is one kind of Tsubokuri, in which a lens edge end of a rear refractive surface of a minus lens whose refractive degree is large (thick in an edge surface) is chamfered flatly, which are terms used generally in the field of spectacles.

Further, although not shown in the drawing, also in a case where “Course”, “lens”, “Frame”, “Chamfer”, “Mirror face”, and “Beep sound” other than “Lens type” are set, the indicator PE 2 is adjusted to “Course”, “Lens”, “Dame”, “Chamfer”, “Mirror face”, and “Beep sound” sequentially to perform execution whereby the following selection items are displayed on the third detail display area E 64 .

That is, when the indicator PE 2 is adjusted to “Course” in the second detail display area E 63 , items such as “Auto”, “Try”, “Monitor”, and the like are displayed on the third detail display area E 64 . Further, when the indicator PE 2 is adjusted to “Lens” in the second detail display area E 63 , items such as “High-index”, “Glass”, “Polycarbonate”, “Acrylic”, “Nothing” and the like are displayed on the third detail display area E 64 .

Further, when the indicator PE 2 is adjusted to “Frame” in the second detail display area E 63 , items such as “Metal”, “Cell”, “Plastic”, “Optil”, “Flat”, “Grooving (small)”, “Grooving (medium)”, “Grooving Barge)” and the like are displayed on the third detail display area E 64 . Here, the “Metal” means processing a lens adjusted to a metal frame; “Cell” means processing a lens adjusted to a cell frame, and “Flat” means perform flat processing.

Further, when the indicator PE 2 is adjusted to “Chamfer” in the second detail display area E 63 , items such as “Nothing”, “Small”, “Medium”, “Special”, and the like are displayed on the third detail display area E 64 . Further, when the indicator PE 2 is adjusted to “Mirror face” in the second detail display area E 63 , items such as “Presence”, “Nothing”, “Chamfer part mirror face”, and the like are displayed on the third detail display area E 64 .

Further, when the indicator PE 2 is adjusted to “Beep sound” in the second detail display area E 63 , items such as “Presence”, “Nothing”, and the like are displayed on the third detail display area E 64 .

Accordingly, at the initial setting time, “Lens type” is set to “Single vision” as described above, for example, “Course” is set to “Auto”, “Lens” is set to “High-index”, “Frame” is sot to “Metal”, “Chamfer” is set to “Small”, and “Mirror face” is set to “Chamber part mirror face” whereby “Single vision” is displayed on the function display part H 1 corresponding to a display of “Lens type”, “Auto” is displayed on the function display part H 2 corresponding to a display of “Course”, “High-index” is displayed on the function display part H 3 corresponding to a display of “Lens”, “Metal” is displayed on the function display part H 4 corresponding to a display of “Frame”, “Small” is displayed on the function display part H 5 corresponding to a display of “Chamfer”, and “Chamfer part mirror face” is displayed on the function display part H 6 corresponding to a display of “Mirror face”.

<Setting of Pop-up Display>

When the cursor-type pointer PE 3 of the third detail display area E 64 shown in FIG. 15 is adjusted to “Setting of pop-up display” shown in FIG. 19 to select (designate), after which the function key F 6 is depressed for execution, items of “Lens type”, “Course”, “Lens”, “Frame”, “Chamfer”, “Mirror face”, and “Beep sound” are displayed on the first detail display area E 62 as shown in FIG. 20 .

When the cursor-type pointer PE 1 of the first detail display area E 62 shown in FIG. 20 is adjusted to “Lens type” shown in FIG. 19 to select (designate), after which the function key F 6 is depressed for execution, items of “Single vision”, “Eye prescription”, “Progressive”, “Bifocal”, “Lenticular”, “Tsubokuri”, “EX”, “Strong minus”, and “Strong minus” (before setting changing) set at present are displayed on the second detail display area E 64 (displayed rightward of the second detail display area E 63 ). With this display, a letter of “Selection/Release” is displayed on the function display part H 4 corresponding to the function key F 4 .

In this state, in a case where a spectacles lens that is not often used out of spectacles lenses of “Bifocal”, “Lenticular”, “Tsubokuri”, “EX”, “Strong minus”, and “Strong minus” is present, a worker can delete this spectacles lens by operation of the cursor-type pointer PE 3 and the function key F 4 . For example, in a case where “EX”, “Strong minus”, and “Strong minus” out of “Bifocal”, “Lenticular”, “Tsubokuri”, “EX”, “Strong minus”, and “Strong minus” are spectacles lenses that are not used often, the indicator pointer PE 3 is adjusted to items of “EX”, “Strong minus”, and “Strong minus” sequentially and selected (designated) after which a command “Selection/Release” of the function display part H 4 is executed by operation of the function key F 4 whereby the “EX”, “Strong minus”, and “Strong minus” selected by the cursor-type pointer PE 3 can be deleted sequentially Thereby, in the pop-up display when the function key F 1 is clicked described previously, the selected items of “Single vision”, “Eye prescription”, “Progressive”, “Bifocal”, “Lenticular”, and “Tsubokuri” as shown in FIG. 12 are displayed.

Further, in a case where “Bifocal”, “Lenticular”, “Tsubokuri”, and the like are not included in the pop-up display as shown in FIG. 12 , the worker can add also “Bifocal” or “Tsubokuri”. In this case, for example, in a case where the item of “Bifocal” is desired to be added, “Setting”→“Setting changing mode”→“Setting of pop-up display”→“Lens type” on the menu screen are selected sequentially, and the cursor-type pointer PE 2 is adjusted to “Bifocal” and executed by the function key F 5 whereby that is added, and the “Bifocal” can be also displayed in the pop-up display.

Thereby, the worker can add or delete the items displayed in the pop-up display according to his taste, leading to improve the efficiency of work often carried out normally. Further, in a case where out of items displayed according to the taste of the worker, the using frequency of an item used often, for example, an item of “Progressive” is many as compared with other items, the item of “Progressive” can be rearranged for display so that it can be displayed at the head in the pop-up display. Further, a learning function can be also provided so as to make the display at the head and the rearranging display according to the using frequency.

<Setting of Layout Initial Value>

When the cursor-type pointer PE 3 of the third detail display area E 64 of FIG. 15 is adjusted to “Setting of layout initial value” and selected (designated) after which the function key F 6 is depressed for execution, items of ←“B→”“FPD”, “PD”, “UP” and “Initial value” are displayed on the first detail display area E 62 as shown in FIG. 22 . At this time, numerical values of set contents “15.0”, “70.0 ”, “64.0”, and “+2.0” before setting changing are displayed corresponding to “←B→”, “FPD”, “PD”, “UP” and “Initial value” on the second detail display area E 63 . These numerical values can be changed in setting according to the taste of the worker with respect to the respective items.

For example, it is possible when layout data in the spectacles processing that an input of bridge width (B) of spectacles frame is changed in setting from an initial value of 15.0 mm to an initial value of 13.0, an input of geometrical center distance (FPD) of spectacles frame is changed in setting from an initial value of 70.0 mm to an initial value of 65.0, an input of pupil distance (PD) of a wearer of spectacles frame is changed in setting from an initial value of 64.0 mm to an initial value of 65.0, and an input of upper drawing value (UP) in a case where a position of a pupil of a wearer of spectacles is located upward from that of normal position is changed in setting from an initial value of +2.0 mm to an initial value of +1.0. This changing operation can be carried out by adjusting the indicator PE 1 to the items of “←B→”, “FPD”, “FD”, “UP” and “Initial value”. Moving the indicator PE 2 together with the indicator PE 1 , and operating, for example, the switch 7 d of the operating panel 7 at the moved position.

When all the input of the initial value are finished, “Execution” is clicked whereby the setting changing of the initial value is completed.

It is noted that “Setting changing mode” includes, in addition thereto, “Setting of a display screen”, “Setting of an adsorption mode”, “Setting of size”, and “Contrast adjustment of a screen”, and the respective setting can be changed according to the taste of the worker.

The “Setting of a display screen” is an item for carrying out setting with regard to the screen display.

The “Setting of an adsorption mode” is enabled three types of setting, though, in a case-of grinding spectacles lens, chucking the front and rear refractive surfaces of the lens by a lens rotating shaft, if the chucking position is a geometrical center position (a box center or a form core) of the spectacles frame, or if it is a pupil center (an optical core) of eyes of a spectacles wearer; or if two kinds of chucking positions are set to be changeable according to the lens kind.

Further, the “Setting of size” is an item for setting processing size in lens processing according to material of spectacles frame, cell, metal, optil (a soft frame out of cell frames), and flat (for example, a two-point frame).

The “Contrast adjustment of a screen” is an item for carrying out contrast adjustment of liquid crystal monitor.

When the cursor-type pointer PE 1 is adjusted to “Setting of size” to select (decide) as shown in FIG. 23 from the first detail display area E 62 shown in FIG. 15 after which the function key F 6 is depressed to execute (decide), items of “Grindstone position correcting mode”, “Zero adjustment mode of finish size”, “Yagen position adjustment mode”, “Shaft adjustment mode”, “PD adjustment mode”, and “Chamfer/grooving adjustment mode” are displayed on the second detail display area E 63 .

The “Grindstone position correcting mode” is an item for correcting and adjusting the center distance between the lens rotating shaft and the grindstone rotating shaft. The “Zero adjustment mode of finish size” is an item in which when a spectacles lens is processed in finish, for example, an error in processed size caused by an error or the like of a chucking position of the spectacles lens is adjusted. The “Yagen position adjustment mode” is an item for adjusting a Yagen crest position, for example. The “Shaft adjustment mode” is an item for shaft adjustment necessary for processing a spectacles lens so that for example, an astigmatism shaft of an eye of a spectacles wearer. The “PD adjustment mode” is an item for adjusting a PD error caused by a chucking error (adsorption error) of a spectacles lens. The “Chamfer/grooving adjustment mode” is an item for adjusting an error caused by the chamfer process/grooving process.

The setting or setting changing is similar to the setting of layout initial value described above, explanation of which is therefore omitted.

<Maintenance>

When the cursor-type pointer PE 1 is adjusted to “Maintenance” to select (decide) as shown in FIG. 24 from the first detail display area E 62 shown in FIG. 15 after which the function key F 6 is depressed to execute (decide), items of “Process number display mode”, “Grindstone dressing mode”, “Cleaning mode”, “Grindstone exchanging mode”, and “Serviceman mode” are displayed on the second detail display area E 63 .

When for example, the cursor-type pointer PE 2 is adjusted to the item of “Serviceman mode” to select (designate) after which the function key F 5 is depressed to execute (decide), the third detail display area E 64 displaying a code number is displayed. And, when a code number “+0.25” is input in the third detail display area E 64 by a “−+” switch 7 d , items of “Correction value”, “Process” and “Other” are displayed on the first detail display area E 62 .

When from that state, for example, the cursor-type pointer PE 1 is adjusted to the item of “Correction value” to select (designate) after which the function key F 6 is depressed to execute (decide), items of “Reference value write”, “Corrected value change”, and “Corrected value change (HEX display)” are displayed on the second detail display area E 63 .

Further, for example, when the cursor-type pointer PE 2 is adjusted to the item of “Corrected value change (HEX display)” of the second detail display area E 63 to select (designate) after which the function key F 6 is depressed to execute, “00-0F” is displayed on the second detail display area E 63 , and the third detail-display area E 64 is displayed.

And, when the function key F 1 is operated to move the cursor-type pointer PE 1 , and the cursor-type pointer PE 1 is adjusted to one of “00-0F” of the first detail display area E 62 , the cursor-type pointer PE 2 is also moved together with the cursor-type pointer PE 1 and adjusted to one of “00-0F” of the second detail display area E 63 , and the cursor-type pointer PE 3 of the third detail display area E 6 is also moved together with the cursor-type pointers PE 1 and PE 2 . At this time, the cursor-type pointers PE 1 and PE 2 select the same one out of “00-0F”, and the cursor-type pointer PE 3 moves to the same position as the cursor-type pointers PF 1 and PE 2 . The corrected value selected out of “00-0F” is displayed on the third detail display area E 64 and can be changed by operation of the “−+” switch 7 d . Thereby, smooth maintenance displaying the work in the serviceman mode in blanket can be carried out.

[Icon, Indicator (Indicator) and Display Area Or the Like]

On the upper edge of the liquid crystal display device 8 are provided display parts of “Layout” tab TB 1 , “Processing” tab TB 2 , “Processed” tab TB 3 , and “Menu” tab TB 4 as mentioned above, and on the lower edge of the liquid crystal display device 8 are provided the function display parts H 1 -H 6 corresponding to the function keys F 1 -F 6 . On the portion of “Processing” of the tab TB 2 are provided a plurality of indicators (indicators) C 1 -C 12 for right use, and a plurality of indicators (indicators) C 1 -C 12 for left use vertically corresponding to each other. The indicators C 1 -C 12 are used as level display means for displaying a level according to the progressive circumstances of lens grinding work from the step for measuring a lens edge shape of a spectacles lens to the step for terminating the grinding process of a spectacles lens on the basis of the ball shape data.

Further, the liquid crystal display device 8 is provided with an icon display area E 1 positioned downward of the indicators (indicators) C 1 -C 12 , juxtaposed to left and right a message display area (input type display means) E 2 and a numerical value display area (input type display means) E 3 positioned downward of the icon display area E 1 , and provided with a state display area (input type display means) E 4 positioned downward of the display areas E 2 , E 3 . These display areas E 1 -E 4 are designed as follows.

(i) Icon display area E 1

Icon display area E 1 is provided with icons A 1 -A 12 as shown in FIG. 27A corresponding to the indicators C 1 -C 12 of “Processing”.

The icon A 1 represents a state for measuring a lens edge shape of a spectacles lens on the basis of lens shape information (θi, ρi) as bait shape data. The icon A 2 represents a state that a Yagen shape formed in a lens edge end of a spectacles lens, The icon A 3 represents a state that a lens edge end is subjected to rough processing. The icon A 4 represents a state that a lens edge end is subjected to finish processing. The icon A 5 represents a state that a lens edge end is subjected to mirror face processing. The icon A 6 represents a state that a lens edge end is subjected to Yagen grooving processing. The icon A 7 represents a state that a lens edge and is subjected to Yagen grooving/chamfering processing. The icon A 8 represents a state that a lens edge end is subjected to Yagen grooving/chamfering/mirror face processing. The icon A 9 represents a state that a lens edge end is subjected to Yagen processing. The icon A 10 represents a state that a lens edge end is subjected to Yagen grooving/chamfering processing. The icon A 11 represents a state that a lens edge end is subjected to Yagen grooving/chamfering/mirror face processing. The icon A 12 represents that grinding processing of a spectacles lens has finished.

It is noted that the icons A 3 -A 11 comprises an icon group representative of a state for processing a lens edge end, and suitable icons can be used according to the function or the like of apparatus body (for example, such as an apparatus without mirror face processing means)

Further, patterns of the icons A 1 -A 12 are not particularly limited as long as they are those by which an operator is able to easily recognize work contents such as processing kinds. Similarly, the work contents may be displayed in the form of a letter, and the work contents may be displayed in letter attaching to the icons A 1 -A 12 displayed with patterns.

Incidentally, these icons A 1 -A 12 are provided every lens grinding work. Moreover, The icons A 1 -A 12 correspond by one to one to a plurality of indicators (indicators) C 1 -C 12 provided on the “Processing” tab TB 2 and lighted and displayed according to a series of progressive circumstances of the lens grinding work so that an operator is able to identity a series of progressive circumstances of lens grinding work.

The indicators C 1 -C 12 are provided separately in two upper and lower stages for a display of a right eye-lens progressive circumstances and a display of a left eye-lens progressive circumstances. However, only one stage may be provided, and a display for identifying the right eye-lens processing or the left eye-lens processing may be done separately. Further, The indicators C 1 -C 12 may display always or as necessary in an area other than the “Processing” tab TB 2 , for example, a space portion where the tabs TB 1 -TB 4 is moved to one side, or may display adjacently vertically Likewise, as shown in FIG. 29 , the icons A 1 -A 12 may be displayed upwardly of the message display area E 2 .

With respect to the processing not set by a worker, it is possible that the icons for expressing the processing visually and symbolically and the indicators (indicators) C 1 -C 12 juxtaposed to the icons A 1 -A 12 may not be displayed.

For example, as shown in FIG. 27 (B), in a cage where the processing of the lens edge end of the spectacles lens is replaced by the Yagen grooving/chamfer processing, and the mirror processing is not carried out, the display state of the icons A 1 -A 12 is set whereby facilitating confirmation of the setting circumstances.

That is, in a case where the processing of the lens edge end of the spectacles lens is replaced by the Yagen grooving/chamfer processing, and the mirror processing is not carried out, display color of the icon A 5 for mirror processing and the icons A 8 -A 11 in connection with the Yagen (crest) processing is made to be gray or color which is relatively hard to recognize such as void or size (in the Figure, displayed by a fine line). At this time, display color of other icons A 1 -A 4 and the icons A 6 , A 7 and A 12 actually subjected to processing is made to be the same color as layout background color or other bright color that can be recognized relatively easily or size (in the Figure, displayed by thick line). By doing so, confirmation of setting circumstances becomes easy.

Likewise, the indicator C 5 corresponding to the icons A 8 -A 11 not subjected to processing and the indicators C 8 -C 11 a not displayed to improve recognizing properties. It is noted that similarly to the icon display, size of frames of the indicators C 5 , C 8 -C 11 can be displayed to be thinner than that of frames of other indicators C 1 -C 4 and indicators C 6 , C 7 and C 12 . It is noted that more detailed display examples in the setting environments and using environments of these icons A 1 -A 12 and indicators (indicators) C 1 -C 12 will be described later (see FIGS. 60 - 63 ).

(ii) Message Display Area E 2

In the message display area E 2 are displayed various error messages and alarm messages according to states. In a case of alarm messages where a breakage of parts in apparatus or a breakage of a lens to be processed is possibly present, a message can be also displayed beyond an area other than the message display area E 2 so that an operator may easily recognize an error display part EW 1 , as shown in FIG. 30 .

(iii) Numerical Value Display Area E 3

In the numerical value display area (input type display means) E 3 are displayed different contents at the time of inputting layout data, at the time of initial setting and at the time of inputting monitor data.

In the numerical value display area E 3 are displayed, at the time of Inputting layout data, geometrical center distance (FPD value) of left and right lens frames of a spectacles frame as shown in FIG. 31 , pupil distance (PD value) of eyes of a spectacles wearer, vertical direction component UP value (or H 1 p value) of a drawing amount which is a difference between FPD value and PD value, and items of processing size adjustment.

Further, in the numerical value display area E 3 are displayed, at the time of initial setting, an adsorption center of processed lens in addition to FPD, PD, UP and size as shown in FIG. 32 .

Further, in the numerical value display area E 3 are displayed, at the time of inputting monitor data, values in connection with dimensions concerning chamfer processing or mirror face processing as secondary processing of spectacles lens, as shown in FIG. 33 .

In a case where in the lens type, a kind of “Single vision”, “Eye prescription”, “Lenticular”, “Tsubokuri”, “Progressive”, and “Bifocal” is selected, and numerical values are input in accordance with the input systems after which the Yagen top locus (Yagen top position) is obtained according to the spectacles lenses, the Yagen top locus has been heretofore obtained over the whole lens edge using a ratio Yagen system (a system for dividing the lens edge surface at a predetermined rate to obtain a Yagen top position) in the same way.

Therefore, in a case of a spectacles lens such that the size of a lens edge thickness differs according to the radius vector direction such as an EX lens, since the Yagen top position is changed on the basis of the lens edge thickness in the radius vector direction such that the lens edge thickness becomes small, there is a problem that the Yagen top locus cannot be depicted smoothly. Therefore, the worker repeats trial and error how the Yagen top locus is smoothly depicted adequately while suitably selecting if the Yagen top locus is provided by the ratio Yagen system according to the kind of lenses, or if the Yagen top locus is provided by a spherical Yagen system (a system for obtaining the Yagen top position by calculation in consideration that the Yagen top locus is on a spherical surface.

So, in the present apparatus, the conventional method for calculating the Yagen top locus, in which the Yagen top locus is obtained by the ratio Yagen system in the same way, or the spherical Yagen system is suitably employed, or the trial and error is repeated, as described above, is revised whereby the Yagen top locus is obtained.

That is, in the present apparatus, a computing method is divided in advance according to the lens type and the lens edge data so as to relieve labor of the worker repeating the trial and error. To this end, the present apparatus employs:

(1) In case of “Single vision” lens, a calculation method of the spherical Yagen system

(2) In case of “Eye prescription”, “Lenticular”, and “Tsubokuri” lenses, a calculation method of the spherical Yagen system

(3) In case of “Progressive” lens, a calculation method of the ratio Yagen system, and in case of “Bifocal” lens, a calculation method of the spherical Yagen system

(4) In case of EX lens, a Yagen top locus calculation method for obtaining the Yagen top locus by a calculation method of the spherical Yagen system (note that a part includes a Yagen tilt (a method for tilting the Yagen top locus about a predetermined radius vector information position or a shaft))

(iv) State Display Area E 4

In the state display area E 4 are displayed a layout image of spectacles lenses for a right eye and a left eye, a Yagen shape formed in the intermediate (suitable) lens peripheral edge other than maximum, minimum, maximum and minimum of spectacles lens, a lens side shape with the peripheral edge viewed from the side, or a schematic view according to actual processing state.

[Display State of a Liquid Crystal Display Device 8 at the Time of Layout]

<Immediately After Start of System>

When a main power supply (not shown) provided in the lens grinding processing apparatus 2 is turned on to start the system, there assumes a state that the “Layout” tab TB 1 is selected, and “Processing” tab TB 2 and “Processing” tab TB 3 are not displayed but “Menu” tab TB 4 is displayed.

Further, in the starting state that selects “Layout” tab TB 1 , the icon display area E 1 is not displayed, but the message display area E 2 , the numerical value display area E 3 and the state display area E 4 are displayed. In the message display area E 2 is displayed a message such as “Please transfer data of the frame”. This message is a message for requesting a transfer of lens shape information (θi, ρi) of the spectacles frame F read by he frame shape measuring apparatus 1 , that is, a message for urging operation of “Data request” switch 7 c.

Accordingly, in the starting state that the transfer of data is not effected, those relating to concrete processing such as numerical values are not displayed in the numerical display area E 3 and the state display area E 4 .

Further, in be function display parts H 1 -H 6 , a default state (or a detail mode stored in a data memory 42 described later in the previously using state) is displayed, and thereabove, “Lens type”, “Course”, “Lens”, “Frame”, “Chamfer” and “Mirror face” such as modes are displayed.

<Immediately After Requesting Data>

Next, when the “Data request” switch 7 c is operated to transfer data from the frame shape measuring apparatus 1 to the lens grinding processing apparatus 2 , the following are displayed in the display areas E 2 , E 3 , and E 4 as shown in FIG. 35 .

That is, in the message display area E 2 is displayed a layout setting message such as “Please set layout data”. Further, a numerical value (for example, “70.0”) transferred to the column of “FPD” of the numerical value display area E 3 , and a cursor-type pointer P is displayed in the column of “PD”.

Further, in the state display area E 4 are displayed a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL for a left eye, geometrical center marks FRc and FLc, the whole shape F of spectacles frame F, diameters of left and right green lenses (for example, “ø15.5”), “DBL” which is a bridge width (clearance between left and right frames) and its numerical value (for example, “ø15.5”). The numerical value of “FPD” is calculated from DBL and the ball width.

<Completion of Layout Setting>

Here, in the column of “PD” of the numerical value display area E 3 is positioned the cursor-type pointer P as described above. By pressing a “ 59 ” switch from that state, an initial value set in the column of “PD” where the cursor-type pointer P is positioned is displayed. This numerical value is changed by operating the “−+” switch 7 d , and after the change (or in the state of the initial value without change), by pressing the “∇” switch, the cursor-type pointer P is moved to the column of “UP”. Similarly, by operating the “∇” switch 7 e and the “−+” switch 7 d , value and “Size” value are set.

When various values of the numerical value display area E 3 are input and displayed in a manner as described, the following display is made in the state display area E 4 as shown in FIG. 36 . That is, in the state display area E 4 are displayed adsorption cup marks MR, ML for holding a green lens for grinding processing positioned internally of a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL for a left eye, geometrical center marks FRe and FLc, and the frame shape FR for a right eye and the frame shape FL for a left eye. The icons A 1 -A 12 for processing course portion according to the detail mode setting with the operation of the function keys F 1 -F 6 are displayed downward of the state display area E 4 . For example, in a case where the chamfer processing is not carried out, the icons A 7 -A 10 are not displayed, and in a case where even if the chamfer processing is carried out, the mirror face processing of the chamfer part is not carried out, the icons A 9 and A 10 are not displayed.

Further, it may be set so that the indicators (C 1 -C 12 ) are not displayed corresponding to the icons (A 1 -A 12 ) not displayed.

For example, in a case where the chamfer processing is not carried out, the icons A 7 -A 10 not displayed, the indicators (indicators) C 7 -C 10 corresponding adjusting thereto are not displayed in both upper and lower stages. Further, in a case where even if the chamfer processing is carried out, the mirror face processing of the chamfer surface is not carried out, the icons A 9 and A 10 are not displayed, and the indicators (indicators) C 9 and C 10 corresponding adjusting thereto are not displayed in both upper and lower stages.

Further, when the “∇” switch 7 e is depressed after setting the numerical value in the “Size” column, the cursor-type pointer P is returned to the column of “FPD” again, and so, resetting of numerical values is enabled.

<Other Displays of Layout>

(Case of One Eye)

In a case where data transferred from the frame shape measuring apparatus 1 to the lens grinding processing apparatus 2 by the operation of the “Data request” switch 7 c is data of only one frame, the following display is made in the display areas E 2 , E 3 and E 4 as shown in FIG. 37 . That is, a layout setting message such as “Please set layout data” is displayed in the message display area E 2 , and the cursor-type pointer P is displayed on the column of “FPD” of the numerical value display area E 3 . Further, in the state display area E 4 are displayed a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL for a left eye, geometrical center marks FRc and FLc, a one eye shape F of spectacles frame F, diameters of left and right green lenses (for example, “ø64”), and “DBL” which is a bridge width (a clearance between left and right frames). The numerical values of “DBL” and “FPD” are not displayed due to the absence of data, but can be input and selected by default.

(Case of Pattern Data)

In a case where lens shape information (θi, ρi) transmitted from the frame shape measuring apparatus 1 to the grinding processing apparatus 2 by the operation of the “Data Request” switch 7 c is ball form shape data based on a form plate or a ball form model, the following display is made in the display areas E 2 , E 3 and E 4 as shown in FIG. 38 .

That is, a layout setting message such as “Please set layout data” is displayed in the message display area E 2 , and a cursor-type pointer P is displayed on the column of “FPD” of the numerical value display area E 3 . Further, in the state display area E 4 are displayed a ball form shape K, diameters of left and right green lenses (for example, a “ø64”), and “DBL” which is a bridge width (a clearance between left and right frames) showing that a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL for a left eye, geometrical center marks FRc and FLc, and lens shape information (θi, ρi). The numerical values of “DBL” and “FPD” are not displayed due to the absence of data, but can be input and selected by default.

<Case of Bifocal Lens Selection>

In a case where “Bifocal lens” is selected as “Lens type” by the operation of the function key F 1 , a layout setting message such as “Please set layout data” is displayed in the message display area E 2 , as shown in FIG. 39 . At this time, a numerical value (for example, “70.0”) is displayed on the column of “FPD” of the numerical value display area E 3 , and the cursor-type pointer P is displayed on the column of “HPD” of the numerical value display area E 3 . The column of “HPD” of the numerical value display area E 3 and the column of “H 1 p” are divided to left and right, and the cursor-type pointer P is displayed on the column for a right eye divided (input part). The left and right divided state is similarly applied to the case where “Progressive” is selected In the state display area E 4 are displayed a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL for a left eye, geometrical center marks FRc and FLc, a small ball image FRs for a right eye and a small ball image FLs for a left eye, the whole shape F of spectacles frame F, diameters of left and right green lenses (for example, “ø64”), and “DBL” which is a bridge width (a clearance between left and right frames). In connection with the setting method for “HPD” and “H 1 p”, that is carried out using the “−+switch” and the “∇” switch 7 e similarly to the above.

<Case of Frame Replacing Course Selection>

In a case where “Frame replacement” is selected in “Course” by operating the function key F 2 in order to replace only the spectacles frame F making use of the existing lens used previously, the following is displayed in the display areas E 2 , E 3 and E 4 as shown in FIG. 40 .

That is, a layout setting message such as “Please set layout data” is displayed in the message display area E 2 . Since the lens shape information (θi, ρi) has been already received, a numerical value (for example, “70.0”) transferred is displayed on the column of “FPD” of the numerical value display area E 3 , and the cursor-type pointer P is displayed on the column of “PD” of the numerical value display area E 3 . Further, in the state display area E 4 are displayed a right eye mark RM and a left eye mark LM, a frame shape FR for a right eye and a frame shape FL, for a left eye, geometrical center marks FRc and FLc, right eye-lens data Rr based on right eye-lens data, and the whole shape F of an spectacles frame F. Thereby, whether or not the existing lens can be utilized for a new frame-replacing spectacles frame F.

[Display State of the Liquid Crystal Display Device 8 During Machining]

<In Case of Starting the Machining of the Right Eye-Lens (Measurement of the Flange Thickness)>

When various numeric value are set and the “Right” switch 6 c is operated, the tab “Under machining” TB 2 is displayed as shown in FIG. 41 , and at the same time the background color changes and the whole display area turns into a “Under machining” sheet. And within the “Under machining” tab TB 2 indicators C 1 -C 12 are displayed depending on the machining mode, and in the icon display area E 1 under each of the indicators C 1 -C 12 , icons A 1 -A 12 are likewise shown depending on the machining mode. In the numerical value display area E 3 , various numerical values set (determined) are shown. In the state display area E 4 , the right eye mark RM and the left eye mark LM, the frame shape for the right eye FR and the frame shape for the left eye FL, their geometrical central marks FRc and FLc, the marks of suction cups for holding lens materials for grinding MR and ML, the global shape F of the frame of a pair of glasses F, the diameters of the right and left lens “ø64” and “DBL” and their numerical values “15.5” are shown.

At this time, the indicator C 1 for the right eye row is lit. The light color of this indicator C 1 and the color arrangement of other indicators C 2 -C 12 are differentiated. This enables to recognize easily that the flange thickness of the right eye-lens is now measured (“Under machining” process). And even if the flange thickness of the right eye-lens is now measured (“Under machining” process), it is possible to set the layout of the left eye-lens by specifying the “Layout” tab TB 1 . However, as the indicator C 1 for the right eye row is shown by the background color of the layout sheet frame (for example, green), it is easily recognized that the flange thickness of the right eye-lens is now being measured.

In the meanwhile, as a means for enabling the machining process to be recognized, it is possible, for example as shown in FIG. 42 , to show by words “Under measurement” meaning that the flange thickness is being measured in the message display area E 2 , to provide a level indicator MI that successively extends clockwise depending on the state of measurement around the words “Under measurement,” to reverse the state of indication (color) of the icon A 1 , to move the global form F of the frame of a pair of glasses F from the left-side end to the right-side end of the picture frame depending on the state of machining, and other adequate means of level indication may be adopted. And as shown in FIG. 43 , the level indication MI and the indicators C 1 -C 12 may be used concurrently.

<In Case of the Recognition of the Flange Thickness>

When the measurement of the flange thickness is finished, as shown in FIG. 44 , the indicator C 2 is lit, the indication of the numerical values indication area E 3 shifts to a “Size” column, and “Edging” curve and frame curve values are shown in what was the numerical values display area E 3 . And in the “Size” column, a numerical value such as “+0.05” for example is shown, while in the “Edging curve” column a numerical value such as “4.5” for example is shown and in the “Frame curve” column a numerical value such as “5.2” for example is shown.

And in the left-side half of the state display area E 3 , in addition to the right eye mark RM and the left-eye mark LM, in its left-side half the shape of the right-eye-lens RR or the shape of the right-eye frame FR, the geometrical central mark FRc, the optical central mark Ro, the upper lens width RRu, the lower lens width RRd, the right lens width RRr, the left lens width RR 1 , the minimum flange thickness position mark Mtn, the maximum flange thickness position Mtc, the arbitrary flange, thickness recognition position mark Mcf, etc. are shown. And in the right-side half of the state display area E 3 , the edging shape, its position and the numerical value of its flange thickness at a position corresponding to the minimum flange thickness position Mtn, the edging shape Ycf, its position and the numerical value of its flange thickness at positions corresponding to the maximum flange thickness position Mtc, and the edging shape Ytc, its position and the numerical value of its flange thickness at a position corresponding to the arbitrary flange thickness recognition position Mcf, etc. are shown.

And when some “grooving” is selected by means of the function key F 4 for the type of the frame of a pair of glasses F, as shown in FIG. 45 , the shape of grooving and its position and the numerical value of the flange thickness (either the flange depth or the flange width will do) at positions respectively corresponding to the minimum flange thickness position mark Mtn, the maximum flange thickness position mark Mtc, and the arbitrary flange thickness recognition position mark Mcf are shown.

It should be noted in the meanwhile that the groove depth and the groove width are shown differently depending on the type of the glass lens (plastic lens or minus lens, etc.) the scope of the round lens shape information (θi, ρi) (for example, the range of radial angle of the supraaural side of the frame of a pair of glasses F to the supranasal side).

And when a chamfering operation is to be executed by means of the function key F 5 , as shown in FIG. 46 cross sectional shapes are shown in the shape resulting from the combination of the edging shape and the chamfering shape at a position corresponding to the minimum flange thickness position mart Mtn, a position resulting from the combination of the grooving shape a chamfering shape at a position corresponding to the maximum flange thickness position mark Mtc and the arbitrary flange thickness recognition position mark Mcf and the numerical value of the flange thickness (the groove depth or the groove width will do) are shown.

In addition, when both “grooving” and chamfering operations are executed, as shown in FIG. 47 , the cross sectional shape resulting from the combination of the edging shape and the chamfering shape at positions corresponding to the minimum flange width position mark Mtn, and positions where the grooving shape and the chamfering shape are combined at positions corresponding the maximum flange width position mark Mtc and the arbitrary flange width recognition position mark Mcf and the numerical value of the flange width (either the groove depth or the groove width will do) will be displayed.

These indications are not limited to those described above as shown for example by the difference of both the edging and the groove depending on the position of the frame and the difference of sectional shape depending on the variation of type of the frame of a pair of glasses F.

At this moment, the chamfering width of the machined lens can be varied by an angle of θi of the lens shape information (θi, ρi) as the round shape data for the frames of a pair of glasses, and therefore the chamfering shape at the minimum flange thickness position mark Mtn, the chamfering shape at the maximum flange thickness position mark Mtc and the chamfering shape at the arbitrary flange thickness recognition position mark Mcf can be easily identified.

And below the state display area E 3 , the “Entirety” of the “Edging position” display mode, the “−” (anticlockwise) rotation and the “+” (clockwise) rotation in the “Rotation” mode which rotates on the display of the right eye-lens shape RR, and the word “Return” for returning the display state after the rotation back to the former state are respectively shown in the function display sections H 1 , H 2 , H 3 and H 6 so that they may be operated by means of the function keys F 1 , F 2 , F 3 , and F 6 .

<When the Right Eye-lens Machining is Finished>

When the grinding of lens materials to form the right-eye-lens based on the lens shape information (θi, ρi) is finished, as shown in FIG. 48 , all the indicators C 1 -C 12 on the right eye row are lit, and the indicator-type pointer P in the numerical value indication area E 3 is in the “Size” column. Then, the display of the right-eye mark RM in the state display area E 4 is reversed and at the same time right eye-lens shape RR is displayed by a dotted line.

<When the Left Eye-lens is to be Machined>

When the machining of the right eye-lens is completed followed by a confirmation of the edging shape, and the “Left” switch 6 b is operated to finish the frame shape grinding of the left eye-lens, as shown in FIG. 49 , the indicator C 2 in the left eye row is lit. At this moment, the numerical value display area E 3 shifts to the display of the “Size” column, where a numerical value such as for example “+0.05” is shown. And in the “Edging curve” column a numerical value such as for example “4.5” is shown and in the “Frame curve” column a numerical value such as for example “5.2” is shown.

[Display State of the Liquid Crystal Display Device 8 After the Machining is Finished]

<In Case of a Confirmation>

After the machining of both lens are completed, the operation of the “Right” switch 6 c and the “Left” switch 6 b and the operation of the “Right” switch 6 c and the “Left” switch 6 b when the machining of the subsequent frame of a pair of glasses F begins results in the words “Machining finished” tab TB 3 being displayed and its background color being changed and shifting to the state of finished machining sheet.

It should be noted in the meanwhile that the state of display at this moment is the same as that of FIG. 48 except that the display of “Machining completed” tab TB 3 and the background is different when the “Right” switch 6 b is operated.

Moreover, even when the “Under machining” tab TB 2 shown in FIG. 53 shifts to the “Machining completed” tab TB 3 , the indicators (indicators) C 1 -C 12 showing the machining state of the right and left eye-lens (R and L) and the icons A 1 -A 12 in the display area E 1 showing the shape of glass lens and a whetstone and other characters representing the type of processing continue to be displayed as before. Thus, the indicators C 1 -C 12 and the icons A 1 -A 12 continue to be displayed even if the tabs TB 1 -TB 4 are changed, whatever operations among the “Layout,” “Under machining,” “Machining completed,” or “Menu” may be performed, it is possible to recognize to what step the processing of either one of the right and left glass lens has progressed at present.

[Examples of Error Display]

<At the Time of Setting the Layout>

As the case of displaying errors during the setting of the layout, a probable case is that of displaying an error display window EM 1 to prompt modifications in the layout setting as shown in FIG. 54 . And at this moment, depending on the error particular, displays are made in the function display sections H 1 -H 6 for giving instructions to avoid errors (or OK) by operating the function keys F 1 -F 6 . In the preferred embodiment of this invention, arrangements are made to have the function display section H 1 display “Yes,” and the function display section H 2 indicate “No.” These “Yes” and “No” correspond to the “Yes” and “No” shown in the error display window EM 1 .

<Under Machining>

As the cases of displaying errors during the control on grinding of lens, there are following cases. When there is a risk of damaging lens to be machined or that of components of a lens grinding apparatus 2 , an error display, window EM 2 showing the particulars of the error is displayed as shown in FIG. 55 before the lens to be machined or the lens grinding apparatus 2 is damaged due to the machining operation to inform the operator of the error that may cause damages and to protect the lens to be machined and the lens grinding apparatus 2 .

And in case where a state of being unable to machine due to a layout error develops (is detected) when machining is to be actually executed according to the layout set as shown in FIG. 56 , an error indication window EM 3 indicating the fact is displayed to inform the operator of the particulars of the error and to take steps to assure that the layout will be changed.

And when an OK command is given by means of function keys (in this case the function key 1 ) based on the error shown in FIG. 56 , as shown in FIG. 67 , the error display alone shifts to the non-display state and at the same time a indicator-type pointer P is displayed.

[A Example of Displaying the Data Storage]

When the machining of the lens of both eyes is completed, as shown in FIG. 58 , the “Layout” tab TB 1 is displayed again and the background color changes to shift to the state of the layout setting sheet.

In this state, a message display window EM 4 is displayed as shown in FIG. 58 for confirming whether “FPD” and other numerical value data and “Lens type” and other processing mode data are stored or not. At this moment, the function display sections H 1 -H 6 display particulars so that response operations based on the message shown in the message display window EM 4 may be executed by means of the function keys F 1 -F 6 . In this preferred embodiment, the function keys F 4 and F 5 are not used as shown in FIG. 58 , the function display sections H 5 and H 6 are not displayed. And in the function display section H 1 the word “Tray” is displayed, in the function display section H 2 the word “Storage” is displayed, in the function display section H 3 the word “Call” is displayed, and in the function display section H 6 the words “Return to the former state” is displayed.

And when the word “Storage” is selected from this state (when the function key F 2 is operated), as shown in FIG. 59 , a display window EM 5 for storing data is displayed, and an input window EM 51 for inputting the storage number (address) for storing data is displayed within the display window EM 6 . And the guides (“↑” and “↓”) for changing the storage number by means of the function keys F 1 and F 2 are displayed in the function display sections H 1 and H 2 , while the guide (“determine”) for instructing the determination of the storage number by means of the function key F 3 is displayed in the function display section H 3 , to complete a series of lens machining routine.

In this way, even if for example “FPD” and other numerical value data and “Lens type” and other processing mode data are changed, the data are stored. It is also possible to review the history of data that have been changed so far, and to prevent the duplication of inputs and input errors in data processing.

[Examples of Applying Machining and the Examples of Displaying Icons and Indicators During the Process]

As for machining not set by the operator, icons A 1 -A 12 and indicators (indicators) C 1 -C 12 can be displayed as follows. For example, icons A 1 -A 12 for machining not set can be displayed visually and symbolically, and indicators (indicators) C 1 -C 12 corresponding to icons A 1 -A 12 for machining not set may not be displayed.

In the meanwhile, the icon A 1 -A 12 corresponding to the machining set may be displayed visually and symbolically and the indicators (indicators) C 1 -C 12 corresponding to these icons A 1 -A 12 for machining set may not be displayed. In this case, those icons corresponding to the machining not set from among the icons A 1 -A 12 may be displayed normally or may be displayed with a fine line.

And in case changes or additions are made in the process of work, the display state may be modified depending on the situation resulting therefrom as shown in FIGS. 60-63 . Incidentally, in FIGS. 60-63 , in particular with regards to the drawing (B) and thereafter, codes are omitted for the sake of convenience (except those not provided on each drawing (A)).

<In the Case of Grooving and Chamfering>

When only grooving and chamfering works are performed and no other Edging machining and mirror machining works are executed in the process of grinding lens, the displays in the function display sections H 1 -H 6 are selected as follows.

In the initial setting of F key described above, by setting the “Lens type” at “Single vision”, the “Course” at “Auto”, the “Lens” at “Plastic,” the “Frame” at “Metal”, the “Chamfering” at “Middle”, and the “Specular surface” at “Specular surface chamber”, in the function display sections H 1 -H 6 of the screen of the liquid crystal display device 8 during the lens grinding control process shown in FIGS. 34-43 , 48 , 53 and 57 the following displays are made. In the function display section H 1 corresponding to the display of “Lens type” “Single vision” is displayed, in the function display section H 2 corresponding to the display of “Course” “Auto” is displayed, in the function display section H 3 corresponding to the display of “Lens” “plastic” is displayed, in the function display section H 4 corresponding to the display of “Frame” “Metal” is displayed, in the function display section H 5 corresponding to the display of “Chamfering” “Middle” is displayed, and in the function display section H 6 corresponding to the “Specular surface” “nil” is displayed.

In this way, by means of the function key F 1 corresponding to “Lens type” “Single vision” is selected, by the function key F 2 corresponding to “Course” “Auto” is selected, by the function key F 3 corresponding to “Lens” “Plastic” is selected, by the function key F 4 corresponding to “Frame” “Metal” is selected, by the function key F 5 corresponding to “Chamfering” “Middle” is selected, and by the function key F 6 corresponding to “Specular surface” “Nil” is selected. And when these selections are executed, setting will be completed only when the following machining begins.

In this state, the icons A 1 -A 12 and the indicators C 1 -C 12 will be displayed as shown in FIG. 27 (B). The operator can confirm again the particulars of settings in this picture, and if any wrong setting is selected, he can avoid a wrong grinding operation by pressing a stop key 6 h at the start of the machining work and thus avoid wasting glass lens.

When a machining work starts from this state, as shown in FIG. 60 (A), the indicator C 1 for the right eye (R) is lit showing that the work process on the glass lens for the right eye has progressed to the measurement of the flange thickness. And upon reception of a message that the measurement of the flange thickness has started, the indicator (indicator) corresponding to the icon for the measuring of the flange thickness are lit. In the similar way, indicators (indicators) of various work processes renews upon reception of starting messages.

The indicators C 2 -C 4 , C 6 , C 7 and C 12 are successively lit and express visually and symbolically as shown in FIGS. 60 (B)- 60 (G) showing instantaneously for each work step that the work process on the glass lens for the right eye has passed through the Edging simulation (FIG. 60 (B)), roughing (FIG. 60 (C)), Hirashiage (FIG. 60 (D)), grooving (FIG. 60 (E)), chamfering (FIG. 60 (F)), and the completion of machining (FIG. 60 (G)).

It should be noted in the meanwhile that among the icons A 1 -A 12 those representing the type of machining that the operator want to execute are lit and those representing works not executed by the operator among the icons A 1 -A 12 remain grey so that operators can avoid making any mistakes. And in case the screen is switched to that of “Layout” during the machining process, the indicators (indicators) C 1 -C 12 do not advance and stays lit at the same position.

<In the Case of Trial Fitting>

FIGS. 61 (A)- 61 (B) show the cases of trial fitting. In case the monitor course is selected, after the whole process stopped at the level of the monitor screen (FIG. 61 (A)), the application of a pressure on the “Refinishing/trial” switch 6 f starts roughing and finishing work, and the process stops at the level of the monitor screen while the indicator C 4 representing finishing work remains lit. Even the application of another pressure on the “Refinishing/trial” switch 6 f does not change the state of indicator indication. And even alter the machining work is restarted, the indicator indication remains unchanged, and upon receipt of a mirror grinding start message, the indicator indication is renewed. When the auto course is selected, however, the normal icon indication and the indicator indication described above are renewed.

<In Case of Machining and Additional Refinishing>

FIGS. 62 (A)- 62 (F) show the case of grooving and chamfering a right eye-lens followed by a refinishing work by setting another mirror grinding work.

When a right eye-lens is grooved and chamfered in the step mentioned in FIG. 60 and then a refinishing work is performed by setting another mirror grinding operation, a mirror grinding work is added while the grooving and chamfering operations shown in FIG. 62 (A) is progressing and the “Refinishing/trial” switch 6 f are pressed. A push on this switch 6 f cancels the indication of the indicators C 1 -C 3 , C 6 and C 7 corresponding to the step of machining completed and brings about at the same time the indication of the indicators C 4 , C 5 and C 8 necessary for executing additional machining.

As shown in FIG. 62 (A), however, the lit state of the icons A 5 and A 8 (color of indication or the thickness of the frame line) may be changed at the time of additional specification for confirming additional machining and then the indicator indications shown in FIG. 62 (B) may be changed when a pressure is applied on the “Refinishing/trial” switch 6 f And also the icon indications and the indicator indications shown in FIG. 62 (B) may be changed when a pressure is applied on the “Refinishing/trial” switch 6 f.

When the machining operation is started again from this state, as shown in FIGS. 62 (C)- 62 (E), icons and indicators are successively lit to show instantaneously and express visually and symbolically the fact of passing through the steps of starting the finishing work (FIG. 62 (C)), starting the mirror grinding (FIG. 62 (D)), starting the chamfering of the specular surface (FIG. 62 (E)), and ending the machining work (FIG. 62 (F)).

<In Case of Shifting From the Grooving of the Flange to Edging>

FIGS. 63 (A)- 63 (D) show the case of grinding the left eye-lens by shifting from grooving the flange to edging after the refinishing work of the right eye-lens shown in FIG. 62 .

After finishing the refinishing work on the right eye-lens shown in FIG. 62 as described above (FIG. 63 (A)), a shift from grooving on the edge to edging for the grinding of the left eye-lens corresponded to grooving, chamfering and mirror grinding on the right eye-lens. Therefore, the indicators C 1 -C 8 and the indicator C 12 corresponding to the entire machining are lit (FIG. 63 (B)) and at the same time the indications of the indicators C 1 -C 5 and C 9 -C 12 on the left eye-lens side and the indications of icons for edging, chamfering and mirror grinding are switched (FIG. 63 (C)).

From this state the machining of the right eye-lens starts (FIG. 63 (C)), and in the same way as described above the indicators and icons are successively lit to be remarkable instantaneously and to express visually and symbolically (FIG. 63 (D)).
