DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be described hereunder with reference to FIGS. 1 to 14 .

First Example 1 of Push-Button Switch Member

A first example of a member for the push-button switch, called hereinlater as push-button switch member, of the first embodiment of the present invention will be first described.

With reference to FIGS. 1 and 2 , reference numeral 1 denotes a liquid crystal touch panel comprising a liquid crystal display element 2 and a touch panel switch 6 mounted to the liquid crystal display element 2 .

On the front display side surface (upper side surface as viewed) of the liquid crystal element 2 , is provided an upper transparent resin base member (substrate) 7 , which has an inner surface on which a movable contact 8 is disposed. A lower transparent resin base member 9 is also disposed so as to oppose to the upper transparent resin base member 7 , and the lower transparent resin base member 9 has an inner surface on which a stationary contact 10 is disposed, so that when the movable contact 8 contacts the stationary contact 10 , a circuit arranged on the stationary contact side is closed, thus forming a touch panel 6 assembled in the liquid crystal panel 1 .

In an actual structure, a plurality of movable contacts 8 are arranged to the upper transparent resin base member 7 at portions corresponding to respective display portions 11 of the liquid crystal display element 2 , and key-top portions 12 are disposed on the upper side surface of the upper transparent resin base member 7 at portions corresponding to the movable contacts 8 , respectively, the key-top portions 12 acting as push-operation elements when depressed.

That is, when viewed from directly upper side portion of the liquid crystal touch panel 1 , i.e. from a direction of FIG. 1 perpendicular to the drawing paper surface, the movable contacts 8 , the display portions 11 and the key-top portions 12 have aligned or overlapped positional relationship.

The key-top portions 12 are integrally fixed to the upper surface of the upper transparent resin base member 7 , and as occasion demands, is applied a cover 14 thereto, which has holes 13 each having a size slightly larger than an outer size of each of the key-top portions 12 to thereby protect the outer portion of the key-top portions 12 . That is, when the cover 14 is applied, only projected portions of the key-top portions 12 are exposed outside the cover 14 through the holes 13 .

Further, to the lower surface of the liquid crystal element 2 , are disposed light source(s) 15 and reflecting (reflector) plate 16 .

The liquid crystal element 2 has a display function in accordance with the preliminarily set positions of the respective movable contacts 8 , and necessary functions are optionally allotted, the allotted functions being displayed through image or text such as letters, symbols, pictures, graphic designs or photographs. According to such structure, different texts or images of the numbers of the movable contacts 8 disposed at portions corresponding to the positions 11 of the liquid crystal element 2 can be displayed, and the displayed texts or images can be displayed to the respective key-top portions 12 .

Since it is of course a matter of free choice how functions are to be allotted to the respective movable contacts 8 , the same functions may be allotted to different movable contacts 8 as occasion demands, and in such case, the same texts or images are displayed on the key-top portions of the movable contacts 8 having the same functions.

Further, a plurality of functions are applied to the circuit of the stationary contacts 10 corresponding to the respective key-top portions 12 in accordance with ways how signals are applied. In such a case, it becomes possible to change the display of the function to the key-top portions 12 by displaying the texts or images corresponding to those functions to the display portions 11 corresponding to the stationary contacts 10 .

According to such structure, it becomes possible to realize a plurality of functions with a reduced number of key-top portions 12 , so that the size of the push-button switch cover member can be made itself compact. Therefore, the electrical or electronic equipment provided with such cover member can also be compact and the flexibility of design can be enhanced. This provides an electric or electronic equipment suitable for requirements of users.

An actual operation of the push-button switch member of the structure mentioned above will be described hereunder through an example.

For example, with reference to FIG. 1 , when a key-top portion 12 on which a letter (numeral) “7” is displayed is depressed by a finger 5 , the upper transparent resin base member 7 of the touch panel switch 6 is depressed to thereby contact the movable contact 8 disposed to the inner surface of the base member 7 to the stationary contact 10 disposed to the inner surface of the lower transparent resin base member 9 . According to this operation, the circuit opened by the stationary contact 10 is closed and the function corresponding to that circuit is achieved.

In this example 1, although the liquid crystal element as an electronic equipment is adopted, the push-button switch member of this embodiment will be applicable to a plasma display panel, EL (electronic luminescence) lamp panel or like. Moreover, when this push-button switch member is applied to an electric or electronic equipment requiring no portability (portable function), the switch member may be applied to a CRT display means.

Second Example of Push-Button Switch Member

A second example of the push-button switch member will be described hereunder with reference to FIG. 3 .

A plurality of circuits performing predetermined functions are formed on a circuit board 17 , and stationary contacts 10 in opened state are provided for these circuits, respectively.

A click plate 19 is mounted so as to cover the printed circuit board 17 through a spacer 20 , and a plurality of conical (corned disc) spring portions 18 each having an inverted bowl shape are formed to this click plate 19 so as to oppose to the stationary contacts 10 , respectively. A movable contact 8 capable of being contacted to the stationary contact 10 is mounted to the lower surface portion of the top portion of the conical spring portion 18 .

Above the click plate 19 , there is disposed a cover member 24 so as to cover the click plate 19 . This cover member 24 is formed with key top portions 12 , each having a downward projection 21 , which pushes the top portion of the conical spring portion 18 by depressing the key top portion 12 by a finger, for example, and the key top portions 12 are continuous to support portions through thin portions 22 .

A liquid crystal display element 2 is mounted to the lower surface of the printed circuit board 17 . The printed circuit board 17 , the stationary contacts 10 , the movable contacts 8 and the key top portions 12 are formed of transparent materials so that the text or image displayed on the liquid crystal element 2 can be observed from the upper portion of the key top portion 12 .

The other structures of this second example are substantially the same as those of the first example mentioned hereinbefore, and accordingly, like reference numerals are added to the portions or elements corresponding to those of the first example and the explanation thereof is omitted herein.

Then, with reference to FIG. 3 , when the push-button switch member of this second example is utilized, one of the key top portions 12 on which a desired function is displayed is pushed (depressed) by a finger 5 , the projection 21 formed to the bottom surface of that key top portion 12 depresses the top portion of the conical spring portion 18 of the click plate 19 disposed thereunder to thereby contact the movable contact 8 formed to the lower surface of the top portion of the conical spring portion 18 to the corresponding stationary contact 10 formed to the printed circuit board 17 . The top portion of the conical spring portion 18 is elastically deformed in a reverse shape just before the contacting of the movable contact 8 to the stationary tact 10 .

Through this contacting of the movable contact 8 to the stationary contact 10 , which has been released, the circuit is closed to thereby perform a predetermined function of this circuit, and simultaneously, a clicking feeling can be obtained due to the elastic deformation of the conical spring portion 18 at the time of depressing the key top portion 12 .

A third example of the push-button switch member will be described hereunder with reference to FIG. 4 .

FIG. 4 is a sectional view of the essential portion of the push-button switch member according to this third example.

On the printed circuit board 17 , there are formed a plurality of circuits for attaining predetermined functions as like as in the second example mentioned above, and a plurality of stationary contacts 10 now released (opened) are preliminarily formed.

A conductive metallic conical spring portion 26 having an inverted bowl shape is disposed to a hole portion 25 of a PET (polyethylene terephthalate) sheet 24 , provided with adhesive, so as to oppose to the stationary contact 10 , and a conical spring fixing sheet 27 is also disposed so as to cover the conical spring portion 26 and the PET sheet 24 .

A cover substrate 28 is disposed so as to cover the conical spring fixing sheet 27 , the cover substrate 28 being formed with a pressing projection 29 abutting against the upper surface of the conical spring fixing sheet 27 at the top portion of the metallic conical spring portion 26 . A support portion 23 is formed to the outer peripheral portion of the pressing projection 29 through a thin thickness portion 22 .

A key top portion 12 is arranged to the upper surface of the cover substrate 28 on a side opposite to the pressing projection 29 . The key top portion 12 is composed of a key top body 30 which is directly subjected to the pressing operation and a flanged portion 31 extending from the lower side surface portion of the key top body 30 . The key top portion 12 is entirely formed of a transparent resin material.

A small-sized liquid crystal display element (electronic display element) 2 is disposed to the lower portion of the flanged portion 31 of the key top portion 12 , the liquid crystal display element 2 having substantially the same size as that of the flanged portion in a plane view.

Further, it is of course to be noted that a number of or plurality of structures including the key top portions 12 and others mentioned above with reference to FIG. 4 are arranged for the push-button switch member of this third example as like as the second example shown in FIG. 3 .

The key top portion 12 , the liquid crystal display element 2 and the back-light 32 are formed as an integral part and the lower surface of the back-light 32 is bonded to the upper surface of the cover substrate 28 . The upper portion of the key top portion 12 and the peripheral portion of the flanged portion 31 thereof are covered by a cover member 33 .

Further, it is of course to be noted that a number of or plurality of structures including the key top portions 12 and others mentioned above with reference to FIG. 4 are arranged for the push-button switch member of this third example 3 as like as the example 2 shown in FIG. 3 .

In this third example, when the key top portion 12 is depressed, the key top portion 12 is depressed inward of the key top cover 33 . However, since the liquid crystal display element 2 is covered by the key top cover 33 , an external force or impact does not directly applied to the liquid crystal display element 2 , thus preventing it from being damaged.

It is preferred that at least upper and lower surfaces of the key top portion 12 are made transparent so that a text or image displayed on the liquid crystal display element 2 can be observed from the upper surface side of the key top portion 12 .

Now, in the present invention, it is not necessarily limited for the text or image on the liquid crystal display element 2 to be observed from the upper surface side of the key top portion. That is, as far as a function of the push-button switch could be displayed to the key top portion 12 providing a press-operation portion, there can be provided a structure in which the text or image can be observed from a side surface side of the key top portion 12 by obliquely arranging the liquid crystal display element 2 , and thus, the design of this structure may be optionally changed.

In the push-button switch member according to the third example represented by the structure of FIG. 4 , although the liquid crystal display element 2 is mounted to the lower surface portion of the key top portion 12 , the liquid crystal display element 2 , having a size or dimension substantially equal to or slightly smaller than the cross sectional surface of the key top body 30 , may be embedded into the key top body 30 .

In such arrangement, since there is no portion, except a terminal, not shown, to be connected to the liquid crystal display element 2 , exposed externally of the key top portion 12 , a possibility for causing any damage to the liquid crystal display element 2 can be further reduced.

The third example of the structure mentioned above will operate and function in the following manner.

As mentioned before, a plurality of structures including the key top portions 12 and others mentioned above with reference to FIG. 4 are arranged for the push-button switch member.

To the liquid crystal display elements 2 disposed to the lower surface portions of the respective key top portions 12 arranged so as to correspond to the respective stationary contacts 10 of the printed circuit board 17 , texts or images corresponding to the preliminarily set functions of the circuits of the stationary contacts 10 are displayed, so that such texts or images displaying the functions can be observed from the upper surface sides of the key top portions 12 .

When a certain key top portion 12 on which a desired function is displayed is depressed by a finger 5 , for example, the pressing projection 29 formed to the bottom surface of the key top portion 12 depresses the top portion of the conductive metallic conical spring portion 26 through the conical spring fixing sheet 27 disposed below the pressing projection 29 .

Then, because the outer peripheral portion of the metallic conical spring portion 26 is contacted to and is restricted by the inner peripheral portion of the hole 25 of the PET sheet 24 , the metallic conical spring portion 26 is deformed so that only the top portion thereof is lowered, and finally, the inner surface of the top portion of the metallic conical spring portion 26 is contacted to the stationary contact 10 . In this operation, just before the contacting of the top portion to the stationary contact 10 , the metallic conical spring portion 26 is elastically deformed in a reverse shape, thus giving a clicking feeling to the finger 5 contacting the key top portion 12 .

According to such operation as mentioned above, through the contacting of the conductive metallic conical spring portion 26 to the opened stationary contact 10 , the circuit of this stationary contact 10 is closed and the function corresponding to this circuit can be attained, as well as an operation feeling of the depressing operation of the key top portion 12 is obtainable.

In the push-button switch member of the third example of the present invention, the liquid crystal display element 2 is formed integrally with the key top portion 12 , there is no portion or element to hinder the display of the text or image displayed on the key top portion 12 and a metallic member having high elasticity is adopted as conical spring portion disposed to the lower portion of the liquid crystal display element 2 , so that high clicking feeling can be achieved, thus obtaining high operating feeling.

Second Embodiment of The Invention

A second embodiment of the present invention relating to a potable information terminal provided with a push-button switch member will be described hereunder.

First Example of Portable Information Terminal

FIG. 5 is an illustration explaining a state of using a portable information terminal provided with the push-button switch member according to the first embodiment mentioned hereinbefore. The example of FIG. 5 is provided with a portable information terminal 34 provided with the push-button switch member of the first through third examples of the first embodiment and also provided with means or function enabling wireless interactive (two-way) communication with another portable information terminal 35 such as PHS or portable telephone having a communication function.

More specifically, in a case where the portable information terminal 34 provided with the push-button switch member is a portable telephone or PHS and another one portable telephone or PHS is used as the other terminal 3 5 and both terminals are under usable conditions, both the portable information terminals 34 and 35 can be communicated through nearest base stations 36 and 37 , respectively.

FIG. 6 is an illustration of one example of a function display design of a key top portion of the portable telephone or PHS of the portable information terminal 34 provided with the push-button switch member.

In the illustrated example, texts or images displayed on the liquid crystal display element may not be ready-made ones and may be ones prepared by a user by using such as electronic camera or image scanner. For example, in a case of a structure that photograph of a father is displayed on one key top portion 12 a to which dialing function to a portable telephone of the father is given, the portable information terminal 34 is connected to the father's portable telephone only by depressing this key top portion 12 a.

Accordingly, in the portable information terminal provided with the push-button switch member of this example of the present invention, since the function of the key top portion 12 which has been just to be operated by a user can be directly observed and recognized from the display on the key top portion 12 , an occurrence of erroneous operation in indexing a name of an object and then dialing or pushing a number plate of a telephone as in a conventional manner can be reduced or eliminated. Moreover, it is possible to call an object (a person at the other end of the line) only by pushing the key top portion 12 on which the photograph of the object is displayed, and accordingly, a communication through the line can be easily, surely and speedily realized, thus being advantageous particularly at an emergency calling time.
