[Prior Art] For example, a remote control commander equipped with a transparent touch panel type XY matrix switch capable of remotely controlling a plurality of electric devices such as a TV and a VTR is provided.
It is disclosed in Japanese Patent Laid-Open No. 62-115993. This is the 7th
More specifically, referring to FIGS. 12 to 12, reference numeral 1 denotes a remote control commander, which has a transparent touch panel type XY matrix switch 3 on the upper surface of the commander body 2. This XY matrix switch 3
Is an upper transparent electrode Y _{1 in which} a plurality of gold or indium oxide alloy (ITO) or the like is vertically deposited on the lower surface of a transparent film (flexible transparent member) made of a polyester film or the like (not shown) by vapor deposition. Y ₂ , ..., Y ₈ (collectively referred to as Y) and a plurality of them in a matrix in the lateral direction (X-axis direction) with a slight clearance from each of the upper transparent electrodes Y via an insulating spacer not shown. Lower transparent electrode X ₁ arranged,
X ₂ , ... X ₈ (collectively referred to as X). The lower transparent electrodes X are connected to the power supply terminal + B via the switches S ₁ , S ₂ , ..., S ₈ of the switch circuit 5, respectively, while the upper transparent electrodes Y are connected to the decoder 6. I am doing it. A timing signal is supplied from the timing circuit 7 to the switch circuit 5, and the switch circuit 5 is sequentially turned on at the timing when the level becomes high as shown in FIGS. Further, the timing signal from the timing circuit 7 is supplied to the decoder 6. Therefore, for example, when the lower transparent electrode X ₁ and the upper transparent electrode Y ₁ are pressed and these portions come into contact with each other, the switch S ₁ of the switch circuit 5 is turned on, and the upper transparent electrode X ₁ is turned on.
Since the power source + B is supplied to the decoder 6 from Y ₁ , the decoder 6 can obtain the detection signal Sc indicating that the transparent electrodes X ₁ and Y ₁ are pressed.

Further, as shown in FIG. 8, a liquid crystal panel (display section) 8 is arranged below the XY matrix switch 3,
The display on the liquid crystal panel 8 can be switched between the TV display (key pattern consisting of channel keys and the like) shown in FIG. 11 and the VTR display (key pattern consisting of playback keys and the like) shown in FIG. The XY matrix switch 3 has a multiple function.

Then, by lightly pressing each part (switch) of the XY matrix switch 3 with a finger or the like, it is possible to perform a remote operation in a mode corresponding to the display on the liquid crystal panel 8. That is, for example, pressing the portion of the X-Y the transparent electrodes X ₃ matrix 3, Y _3, the channel of the TV "channel 6", VT
R can be played "PLAY".

This similar structure is disclosed, for example, in Japanese Patent Laid-Open No. 58-175048.

[Problems to be Solved by the Invention] However, the conventional XY matrix switch 3 described above is used.
Since the upper and lower transparent electrodes Y and X are formed in the same shape and the same width in a rectangular shape, respectively, and are arranged in parallel at equal intervals in a matrix, an XY matrix switch. If the area of the contact (contact) portion of each of the transparent electrodes X and Y is widened in order to ensure the operation when pushing each target pressing portion (target key portion) of 3, the gap between adjacent transparent electrodes Is small, adjacent transparent electrodes are easily turned on, and malfunctions such as double pressing are likely to occur.

In view of this, the present invention provides a remote control commander that can reduce erroneous operations when the target portion of the XY matrix switch is pressed, and further improve operability.

[Means for Solving the Problems] A flexible transparent member, a plurality of upper transparent electrodes arranged laterally or vertically on the lower surface of the flexible transparent member, and each of the upper transparent electrodes via an insulating spacer. A transparent touch panel type XY matrix switch is formed by electrodes and a plurality of lower transparent electrodes arranged in a matrix with a slight clearance.
In a remote control commander in which a display section is arranged below the XY matrix switch and the display of the display section is switchable so that the XY matrix switch has a multiple function, at least one side The transparent electrodes are formed in different shapes and intervals so that they can correspond to the respective displays switched by the display section with respect to the transparent electrodes on the other side.

[Operation] Since the shapes and the intervals of the transparent electrodes on at least one side of the upper and lower transparent electrodes are made different so as to correspond to each display switched by the display unit, Malfunctions and malfunctions at the time of pushing the target portion of the XY matrix switch corresponding to the display switched by the display unit are surely reduced, and the usability is greatly improved.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings. still,
The commander 1 and the like of the remote control shown in FIG. 7 are incorporated, and the same parts as those of the conventional structure are designated by the same reference numerals.

FIG. 1 shows a cross section of the main part of the commander 1 of the remote control. The transparent touch panel type XY matrix switch 3 of the commander 1 includes a transparent substrate 9 made of a glass plate fixed on a liquid crystal (LCD) panel (display unit) 8 by a predetermined means, and an upper surface of the transparent substrate 9. 8 laterally on 9a
Thin transparent lower electrodes X ₁ , X ₂ , ..., X ₈ made of indium oxide composite (ITO), etc. arranged in rows (collectively referred to as X)
And a flexible thin glass plate which is disposed opposite to the upper surface 9a of the transparent substrate 9 via a plurality of transparent silicon rubber dot spacers (insulating spacers) 4 with a slight clearance (for example, 30 to 50 microns). Transparent plate (flexible transparent member) 10
And an indium oxide alloy or the like is vertically vapor-deposited on the lower surface 10b of the flexible transparent plate 10 in a thin film shape, and is arranged in a matrix in five rows with a slight clearance from the lower transparent electrode X. Upper transparent electrodes Y ₁ , Y ₂ , ..., Y ₅ (collectively Y
And a protective film 11 made of a polyester film or the like for covering the upper surface 10a of the flexible transparent plate 10.

As shown in FIGS. 4, 5 and 6, the liquid crystal panel 8 arranged under the XY matrix switch 3 has key patterns composed of TV channel keys, VTR reproduction keys and the like. Key patterns consisting of a key pattern consisting of a DAT DECK start key, etc. can be freely switched, and if each part (each key part) corresponding to the above key pattern of the XY matrix switch 3 is depressed. The remote control of the mode corresponding to the display of the liquid crystal panel 8 can be performed.

Thus, as shown in FIG. 2, the transparent electrodes Y on the upper side are
Are formed in the shape of a long rectangular thin film having the same shape and the same width, and the flexible transparent plates 10 are arranged at equal intervals so as to correspond to the keys arranged in the longitudinal direction of the key patterns.
Are arranged in parallel to the lower surface 10b of each.

The lower transparent electrodes X are arranged so as to correspond to the keys arranged in the lateral direction of the key patterns. Among the lower transparent electrodes X, the transparent electrodes X ₁ and X ₈ located at both the left and right ends are formed in the same shape and the same width rectangle, respectively. The transparent electrodes Y ₁ and Y ₅ are arranged on the upper surface 9 a of the transparent substrate 9 so as to face each other and have a slight clearance. Further, the remaining lower transparent electrodes X _{2 to} X ₇ are slightly arranged so as to be respectively laid over the transparent electrode Y ₂ located at the second stage from the upper side and the transparent electrode Y ₅ located at the bottom stage. It is arranged on the upper surface 9a of the transparent substrate 9 so as to have a sufficient clearance. In detail,
The transparent electrodes X ₂ , X ₃ and X ₄ are arranged at the same width and at equal intervals as the transparent electrodes X ₁ and X ₈ at the above-mentioned ends, but the transparent electrodes located at the bottom of the transparent electrodes X ₂ and X ₃ are transparent. The width of the portion in contact with the electrode Y ₅ is wider than that of the transparent electrode X _{4 and the} like and is close to the transparent electrode X ₄ . This allows
For example, when the TV is displayed, it is used as one key such as "11 channel" and "12 channel", and when the DAT DECK is displayed, "Start" is displayed as the above "11 channel",
It is easy to press when using 2 keys of "12 channels" as 1 key.

The transparent electrode X _5, X _7, said transparent electrodes X _2, X _3, Yes and X ₄ from the larger width, etc. with respect to the transparent electrode X ₆ so as to sandwich the transparent electrodes X ₆ of the most wide They are arranged at a distance. Furthermore, the width of the portion in contact with the transparent electrode Y ₅ is located in the bottom of the transparent electrodes X _5, X _6, the transparent electrode X ₅ located above the bottom of X _7, X _6, X _7, said Yes formed on the transparent electrode X ₄ etc. substantially the same width, each of the transparent electrodes between the transparent electrodes Y ₂ to Y ₄
X ₅ , X ₆ , and X ₇ are close to each other. As a result, for example, when the VTR display is "play" and the DAT DECK display is "play", the position shifts by one key and the two keys are used as one key. It's easy.

According to the remote control commander 1 of the above-described embodiment, the transparent electrodes X ₂ , below the XY matrix switch 3 are
The X _3, X _4, arranged at equal intervals on the transparent electrodes X _1, X ₈ and the width at both ends, in contact with the transparent electrode Y ₅ of the lower located at the bottom of the transparent electrodes X _2, X ₃ Since the width of the part is formed wider than the transparent electrodes X _{4 and the} like so as to be close to each other, when the liquid crystal panel 8 is switched to the TV display, one key such as “11 channel” or “12 channel” is used. It is used, but when pressing the "start" when using the two keys of "11 channel" and "12 channel" as one key like "start" when switched to the display of DAT DECK, Transparent electrode
X ₂ and and the transparent electrode Y _5, since the switch by pressing any of the transparent electrodes X ₃ and the transparent electrode Y _5, or transparent electrode X ₂ and the transparent electrode Y ₅ between the transparent electrode X ₃ is turned on, the conventional It is possible to further improve the pressing operability as compared with the above.

In addition, the width of the portion of the lower transparent electrodes X ₅ , X ₆ , X ₇ that comes into contact with the transparent electrode Y ₅ located at the lowermost stage is formed to have substantially the same width as the transparent electrode X _4, etc. Since each of the transparent electrodes X ₅ , X ₆ , and X ₇ between the transparent electrodes Y _{2 to} Y ₄ of the above is brought close to each other, the above-mentioned “reproduction” when the liquid crystal panel 8 is switched to the VTR display and It is easy to use and easy to use even when using two keys that are shifted by 1 key left and right as 1-key like "Play" when DAT DECK is displayed, it is easy to use.

In this way, since the shape and the interval of the lower transparent electrodes X are made different so as to correspond to the respective keys of the respective displays switched by the liquid crystal panel 8, the X-
Set the part of the Y matrix switch 3 corresponding to the above display to 1
When used alone as a key, malfunction (double press) due to contact with an adjacent key is reduced, and when used as a key for two keys or a part corresponding to two or more keys, which part of the key is pressed Also turned on to ensure that malfunctions are reduced. Therefore, it is possible to surely reduce malfunctions and malfunctions when the target portion of the XY matrix switch 3 corresponding to each key of each display switched by the liquid crystal panel 8 is pressed, and to further improve the usability. You can

Although the lower transparent electrodes X have different shapes and intervals according to the above-described embodiment, the invention is not limited to this, and the upper transparent electrodes Y may have different shapes and intervals, or both transparent electrodes. The shapes and intervals of X and Y may be different from each other. Although the lower transparent electrode X is provided on the glass transparent substrate 9, it may be provided directly on the liquid crystal panel 8.

Also, what is switched and displayed on the liquid crystal panel 8 is a TV
It is needless to say that the display of various electric devices such as an amplifier and a tuner can be switched without being limited to the display such as.

[Advantage of Device] As described above, according to this device, the shape and interval of each transparent electrode on at least one side of the upper and lower transparent electrodes are displayed with respect to each transparent electrode on the other side.
