The present invention relates to an image forming apparatus, and in particular, to an image forming method and an image forming apparatus capable of registering and calling up set value information on functions of the apparatus.
Conventionally, there is a technology that makes it possible to store pieces of information on image forming apparatus's function settings freely made by a user, as a group of information, call up the stored setting information, and overwrite current setting information with the acquired setting information. See Japanese Patent Application Publication No. 2001-285534 (page 7, FIG. 14), for example.
However, in cases where alteration of a set value is made after calling up the setting information, the user's operations to move back and forth through a lot of screens are necessary. Even in cases where data as a combination of various set values is previously prepared and registered individually as a measure to avoid the complexity of the operations, the number of registered pieces of data increases and the operation for making a selection from these data is burdensome.
An image forming method according to the present invention includes a first step of designating a first screen to be a target of recalling among a plurality of screens for making settings and registering a first name while associating the first screen with the first name, in a process of executing a prescribed function; a second step of displaying a redisplay screen that includes the first screen associated with the first name and prompting resetting on the redisplay screen, when the first name is selected; and a third step of executing the prescribed function when the execution of the prescribed function is commanded.
An image forming apparatus according to the present invention includes a display unit that displays a first screen handled as a target of recalling and a second screen not handled as a target of the recalling, as screens for making a setting in a process of executing a prescribed function; a storage unit that stores setting information including a first set value set on the first screen, a second set value set on the second screen and first screen information regarding the first screen, while associating the setting information with a first name; a selection unit that selects the first name stored in the storage unit; and a control unit that controls processing in the display unit, the storage unit and the selection unit, wherein when the first name stored in the storage unit is selected by the selection unit, the control unit displays a redisplay screen including the first screen associated with the first name on the display unit and prompts resetting of the first set value on the redisplay screen.
According to the present invention, setting screens of setting items having a high possibility of resetting, previously selected from a lot of setting items, are successively displayed and the resetting is made possible, by which the complexity at the time of making the setting of each setting item, including the resetting, can be eliminated.
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications will become apparent to those skilled in the art from the detailed description.
The image forming apparatus 1 includes an operation panel 11, a setting information storage unit 16, a setting change designation unit 17, a setting information retrieval unit 18, a setting change flow generation unit 19, a scanning unit 20 for optically reading an image, an image memory 21, a printing unit 22, a transmission/reception unit 23, a control unit 24, a RAM 25, a ROM 26, a CPU 27 and a common bus 28.
The operation panel 11 includes an operation unit 15 and a touch panel 12 serving as a selection unit having a display unit 13 and a display control unit 14 as a control unit, and has functions for operating the image forming apparatus 1, such as logging in through the inputting of authentication information, executing each function, setting each function's condition and the like, and transmitting image data. The setting information storage unit 16 stores setting information held by the image forming apparatus 1.
As will be described in detail, the setting change designation unit 17 temporarily stores data of setting change screens, as setting screens having a high possibility of resetting of a set value and desired to be called up again, in the setting change screen queue 17a in response to an operation on the operation panel 11 so that those setting change screens (e.g. only those setting change screens) are displayed in a wizard format when the setting information is called up by the setting information retrieval unit 18. Among the setting screens, those temporarily registered in the setting change screen queue 17a can be referred to as setting change screens in the following description.
The setting information retrieval unit 18 calls up intended setting information from the setting information storage unit 16. The setting change flow generation unit 19 generates a setting change flow in a wizard format by using screen data of setting change screens temporarily stored in the setting change screen queue of the setting change designation unit 17. The scanning unit 20 makes the image memory 21, for temporarily storing image data, temporarily store scanned image data. The printing unit 22 prints the image data stored in the image memory 21.
The transmission/reception unit 23 transmits and receives data to/from an external device via a telephone circuit or a communication network according to a facsimile communication protocol or a network-related protocol such as TCP/IP. The control unit 24 controls the whole of the image forming apparatus 1 in an integrated manner. The RAM 25 stores a variety of information necessary for controlling operations of various functions of the image forming apparatus 1. The ROM 26 stores in advance information such as control programs of the image forming apparatus 1. The CPU 27 performs arithmetic processing and the like according to commands from the control unit 24. The common bus 28 is a signal line connecting the aforementioned components of the image forming apparatus 1.
In
The display unit 13 (
The display control unit 14 (
The display control unit 14 also has a function of notifying the setting change designation unit 17 of a function name and a screen name of an icon button as will be explained later when the icon button on a setting screen displayed on the display unit 13 is depressed, and a function of acquiring default setting information from the setting information storage unit 16 and comparing the contents of a setting change with the default setting information when a setting operation is completed, identifying each setting item differing from the default, and commanding the display unit 13 to attach an alteration mark to the identified setting item on a screen to be displayed.
This example shows a case where the set values of some setting items have been changed from the default values as will be described later: the sheet feed tray from automatic (i.e., AUTO) to tray #2 (i.e., TRAY2), the scan size from automatic to A4 size (i.e., A4), and the scaling from 100% to 145%, wherein an alteration mark 201d is additionally displayed in each display part (each display button in this example) corresponding to a changed setting item.
As will be described later, the display control unit 14 also has a function of requesting the setting change flow generation unit 19 to generate a setting change flow in a wizard format enabling a further setting change when a command for registering changed setting information is issued, and a function of commanding the display unit 13 to display names, etc. of setting change screens appearing according to the setting change flow as a registration confirmation screen when completion of generating the setting change flow is reported from the setting change flow generation unit 19.
When data of one or more registered setting change screens exist in the setting change screen queue 17a (a case where data of a “sheet feed tray setting screen”, a “TRAY2 sheet size setting screen” and a “scaling setting screen” exist is shown in this example), it is indicated that screens having the names listed in the section “setting change screen” shown in
In contrast, when no setting change screen data has been stored in the setting change screen queue 17a of the setting change designation unit 17, the display unit 13 is commanded to display a registration confirmation screen omitting the section of the setting change screens as shown in
Incidentally, as shown in
The display control unit 14 also has a function of storing a “function name of a function to which each setting item belongs”, a “setting information registration name” and “setting items whose set values have been finalized” in the setting information storage unit 16 as will be explained later when the registration of the setting information is completed, and a function of sending a “setting change flow” registration request to the setting change flow generation unit 19 when a setting change flow is generated by the setting change flow generation unit 19. Incidentally, it is assumed in the following description that the setting information includes “set value information (setting items whose set values have been finalized” and further includes a “setting change flow” in cases where the “setting change flow” has been generated.
The display control unit 14 also has a function of requesting the setting information retrieval unit 18 to call up setting information by designating the setting information as the object of calling up as will be described later when a command for calling up the setting information is issued, a function of performing display screen control and displaying pertinent screens on the display unit 13 according to a setting change flow when the setting change flow is included in the setting information received from the setting information retrieval unit 18, and a function of acquiring the default setting information from the setting information storage unit 16 and comparing the contents of the setting change with the default setting information when the setting change flow is exited, identifying each setting item different from the default, and commanding the display unit 13 to attach the alteration mark 201d (
The setting information storage unit 16 as a storage unit stores the default set value of each of the setting items that have been set as conditions of the functions of the image forming apparatus 1. Table 1 shows the contents of the setting items and their default values stored in the setting information storage unit 16 in regard to the copy function as a prescribed function. The setting information storage unit 16 also has a function of storing pieces of setting information that underwent a setting change by the user's setting operation as a group of information as will be described later.
In an index No. 1, the function name “copy” of the function as an object, setting items corresponding to the function name “copy”, and a setting change flow are stored while being associated with each other as setting information whose setting information registration name is named “special copy”. Incidentally, the setting change flow in this example is shown schematically for the sake of simplicity and the screens shown in this example correspond to the contents of screens shown in
The setting change designation unit 17 includes the setting change screen queue 17a for temporarily storing the data of setting change screens, and has a function of storing setting screen information, including a received function name and setting change screen data as a set of information, in the setting change screen queue 17a when an insertion request to the queue is received from the display control unit 14. Incidentally, the insertion request to the queue occurs when an icon button 202a on the sheet feed tray setting screen 102a shown in
The setting information retrieval unit 18 has a function of acquiring setting information, as the object of calling up, from the setting information storage unit 16 and passing on the acquired setting information to the display control unit 14 when a command for calling up setting information is received from the display control unit 14.
The setting change flow generation unit 19 has a function of successively acquiring setting screen information piece by piece as shown in
the sheet feed tray setting screen 102a (
the TRAY2 sheet size setting screen 103a (
the scaling setting screen 104a (
in this example, from the setting change screen queue 17a of the setting change designation unit 17 and thereby forming a setting change flow for generating setting screens in the wizard format as will be explained later when a request for generating the setting change flow in the wizard format is received from the display control unit 14.
As shown in
The setting change flow generation unit 19 generates a setting change flow for executing a macro. For example, when a setting information registration name “special copy” is selected from a setting information registration name list (corresponding to a list of setting information registration names displayed on a setting information registration name list screen 113 in

Step S107: the set value on the TRAY2 sheet size setting screen 103 is changed from the default value “A4” to “A3” and the TRAY2 sheet size setting screen 103 displayed on the display unit 13 is updated to a changed TRAY2 sheet size setting screen 103a (
Step S108: the screen returns again to the copy standby screen 101a (
Steps S109 and S110 are steps in which a scan size setting screen (not shown) is displayed and the set value is changed from the default value “automatic” (see Table 1) to “A4”. The steps S109 and S110 correspond to processing in transition numbers N109 to N111 in the display transition diagram of
Step S109: a “scan size” button 201e (
Step S110: when the set value on the scan size setting screen is changed from the default value “automatic” to “A4” as a second set value, the display of the scan size setting screen on the display unit 13 is updated.
Thereafter, when the “OK” button on the scan size setting screen is depressed, the display control unit 14 acquires the default set values of the setting items of the copy function from the setting information storage unit 16, compares the default set values with the set values temporarily stored in the display control unit 14, identifies each setting item differing from the default value, and updates the copy standby screen 101a (

Thereafter, when an “OK” button 204e on the scaling setting screen 104a (
Next, the setting information registration operation, corresponding to the processing in the step S114 (setting information registration) in the flowchart of
Step S301: a “register setting information” button 201g is depressed (
Step S302: the display control unit 14 checks whether or not screen information is stored in the setting change screen queue 17a (
Step S303: the display control unit 14 makes the display unit 13 display a second registration confirmation screen 105b (
Step S304: the display control unit 14 requests the setting change flow generation unit 19 to generate the setting change flow (
Step S305: the process advances to step S306 if the setting change flow generation unit 19 has just acquired setting screen information as the first page from the setting change screen queue 17a of the setting change designation unit 17, or advances to step S307 if the acquired setting screen information is the second page or later.
Step S306: the setting change flow generation unit 19 generates a first page screen like the screen shown in
Step S307: when the setting screen information as the second page is acquired, the setting change flow generation unit 19 generates a second page screen like the screen shown in
Step S308: the setting change flow generation unit 19 checks the presence/absence of setting screen information in the setting change screen queue 17a of the setting change designation unit 17, and the process returns to the step S304 if present, or to step S309 if absent.
Step S309: the setting change flow generation unit 19 generates the setting change flow, as display command information implementing the screen transition explained with reference to

Step S312: the display control unit 14 makes the display unit 13 display a software keyboard screen 111 (
Step S313: when an “OK” button 211a on the software keyboard screen 111 (
Further, when a setting change flow has been generated by the setting change flow generation unit 19, the display control unit 14 issues a command for storing the generated setting change flow in the setting information storage unit 16 while attaching the setting information registration name to the command (
In contrast, when no setting change flow has been generated, the set value information (e.g., only the set value information) after the setting change of the copy function is stored in the setting information storage unit 16 while associating the set value information with the setting information registration name “special copy” (
Then, the display control unit 14 displays a registration completion screen 112 (
Next, an operation for calling up setting information having an already registered setting change flow will be described below with reference to a sequence diagram of
In the sequence diagram of
When a “macro” button 201h at the top of the screen is depressed (F201) while the copy standby screen 101 (
The display control unit 14 executes a macro according to the setting change flow whose setting information registration name is “special copy”. First, the display control unit 14 displays the sheet feed tray setting screen 102b (
In this case, the display control unit 14 displays the TRAY2 sheet size setting screen 103b (
In this case, the display control unit 14 displays the scaling setting screen 104b (
In this case, the display control unit 14 makes the display unit 13 display an updated scaling setting screen 104c on which the optional scaling factor displayed in a scaling factor display part 204g has been changed from “145%” on the scaling setting screen 104b to “146%” due to the setting change (F214). It is assumed here that the user checks the displayed settings and thereafter depresses the “next” button 204c (F215).
Since the setting change flow is completed, the display control unit 14 acquires the default set values of the setting items of the copy function from the setting information storage unit 16 (F216-F217), compares the set value information whose setting information registration name is “special copy” passed on from the setting information retrieval unit 18 with the default set values acquired from the setting information storage unit 16 and thereby identifies each setting item differing from the default value (F218), and makes the display unit 13 display an updated copy standby screen 101c (
Incidentally, while an example of executing a macro by registering the “sheet feed tray setting screen”, the “TRAY2 sheet size setting screen” and the “scaling setting screen” as the setting change screens was shown in the above description of the copy function, the operation is not limited to this example; it is also possible to configure the operation to execute a macro by selecting desired items from the setting items of the copy function shown in Table 1 and registering the selected items as the setting change screens.
As described above, in the image forming apparatus 1, when the copy function is executed, setting screens of setting items having a high possibility of resetting, e.g., the setting screens of the “sheet feed tray”, the “TRAY2 sheet size” and the “scaling factor” in this embodiment, are previously designated as the setting change screens. Then, the setting change flow, executing a macro that successively displays these designated setting screens and enables setting changes (e.g., only these designated setting screens) and enables setting changes, and the corresponding set value information are registered in the setting information storage unit as the setting information while attaching the setting information registration name to the setting information. Accordingly, when the user makes a resetting, the user selects an intended setting information registration name, such as “special copy”, from the setting information registration name list screen and thereby makes the resetting by operating the successively displayed setting screens of the “sheet feed tray”, the “TRAY2 sheet size” and the “scaling factor” as needed.
After finishing the above-described settings, the user depresses the start key 15i of the operation panel and thereby makes the image forming apparatus 1 execute a copy process according to the above-described settings.
Incidentally, while set values that were set in the first setting process are displayed on the setting screens displayed at the time of resetting in the example described in the above embodiment, the display of the set values is not limited to this example; it is also possible to display the default values, for example.
While the registration and the calling up of setting information in the operation of the copy function selected from the functions of the image forming apparatus 1 by depressing the copy key 15b (
The setting information storage unit 16 stores the set value and the default value of each of the setting items that have been set as conditions of the functions of the image forming apparatus 1. Tables 2-1 and 2-2 show the contents of the information stored in regard to the scan function.
Also in the scan function operation, the procedure of the setting change operation is carried out similarly to the procedure in the copy function operation shown in the flowcharts of

Incidentally, while examples of executing a macro according to setting items belonging to one of the copy function, the scan function, the fax function and the e-mail function and subsequently executing a corresponding functional process have been described in the above embodiment and first through third modifications, the present invention is not restricted to such examples.
For example, a variety of modes can be employed, such as first executing a macro whose setting information registration name is “scan setting-1” in the scan function described in the first modification, subsequently executing a macro whose setting information registration name is “mail setting-1” in the e-mail function described in the third modification, finalizing the set values, and thereafter successively carrying out the scan process and the e-mail transmission process.

While examples of employing the present invention for an image forming apparatus have been described in the above embodiment, the present invention is not restricted to such examples but is generally applicable to various types of apparatuses having setting information.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of following claims.
