[Industrial application field]

TECHNICAL FIELD The present invention relates to a transparent switch with a click sensation that provides a click sensation when a person presses the switch and allows the user to realize that the switch has been pressed.

2. Description of the Related Art In recent years, input devices have been developed in which input is performed by, for example, touching or pressing with a finger the graphic of a key displayed on a display screen of a CRT display device, liquid crystal display device, or the like.

Such an input device has a transparent switch with touch parts or pressing parts arranged in an X-Y matrix on a display screen, and is operated by touching or pressing a part corresponding to the displayed key shape. By detecting which part of the transparent switch is touched or pressed and sending the detection result to the control unit, it has the same function as a conventional switch on a keyboard or the like.

Since such an input device can arbitrarily change the content displayed on the display screen, it has the advantage that various types of keystrokes can be performed depending on the relationship between the displayed content and the position to be touched or pressed.

By the way, when the above-mentioned transparent switch is touched or pressed, it acts in the same way as pressing down a key on a keyboard, so it is necessary to take care so that a person can perceive that the transparent switch has been touched or pressed.

[Conventional technology]

A conventional transparent switch is configured as shown in FIG. 4, for example. FIG. 4(a) is a plan view, and FIG. 4(b)
is a sectional view taken along arrow CD.

In the figure, 1 is a transparent electrode formed on a transparent film 2, and 3 is a transparent electrode formed on a transparent film 4. These transparent films 2 and 4 are bonded together with a spacer 6 in between. At this time, a certain distance is maintained so that the transparent electrode 1 and the transparent electrode 3 do not come into contact with each other.

The transparent switch configured in this way is placed on the display screen 7 of a CRT display device, liquid crystal display device, etc.
Display screen 7 at the intersection of the transparent electrode 1 and the transparent electrode 3
A key figure is displayed above. The operator presses the area where the desired key figure is displayed to manually operate the keys.

As a result, the transparent electrode 1 and the transparent electrode 3 are brought into contact and electrically conductive, and the positional information of the electrically conductive state is notified to the control unit, so that the pressed key is detected in the same way as when pressing a key on a keyboard. It has become.

At this time, unlike a normal keyboard, the transparent switch does not have any keystrokes, so it is impossible to tell whether or not the key was pressed manually by the feeling of the finger when pressing it.
Therefore, when it is detected that the transparent electrode 1 and the transparent electrode 3 are in contact with each other due to pressing, a buzzer or the like is sounded to inform the operator that the key has been pressed manually.

[Problem to be solved by the invention]

However, in order to notify the operator using a buzzer or the like, it is necessary to equip the device to which the transparent switch is applied with a sounding means or the like, which has the disadvantage of being expensive.

Furthermore, since the buzzer sound is difficult to hear in a noisy environment, the operator presses the transparent switch with more force than necessary. Therefore, there are drawbacks in that extra force is applied to the fingers, resulting in poor operability, and the extra force is used to press the device, which shortens the life of the device.

This invention was made in view of the above circumstances, and it is possible to construct an inexpensive device that does not require a sounding means, and also has excellent operability since no extra force is required, as well as a click-sensitive transparent device that prevents deterioration of the device. The purpose is to train the switch.

[Means to solve the problem]

FIG. 1 is a diagram illustrating the principle of a click-sensitive transparent switch according to the present invention; FIG. 1(a) is a plan view, and FIG. 1(b) is a sectional view taken along the arrow AB.

In the figure, ■ is a strip-shaped first conductor portion formed on the first transparent film 2 and having a predetermined width in one direction;
For example, it is a band-shaped second conductor portion having a predetermined width formed on the second transparent film 2 in a direction intersecting the I-th conductor portion 1 formed on the first transparent film 2. These first transparent film 2 and second transparent film 4 are arranged close to each other.

Then, the first conductor portion 1 and 5. on the first transparent film 2 or the second transparent film 4. A protrusion 5 is provided at a portion where the second conductor part 3 intersects, and by pressing the protrusion 5, the first conductor part 1 and the second conductor part 3 are brought into contact. A transparent switch is constructed that is closed when the

Note that 6 is a spacer for keeping the first transparent film 2 and the second transparent film 4 at a predetermined distance.

[Effect]

As described above, the present invention provides a protrusion 5 at the intersection of the first conductor section 1 and the second conductor section 3 on the first transparent film 2 or the second transparent film 4. Since the key is pressed manually by pressing the protrusion 5, a click feeling can be perceived.

Therefore, no sounding means is required to notify that a key has been pressed. In addition, since a click feeling is obtained, there is no need to forcefully press a key part, resulting in excellent operability and without accelerating the deterioration of the device.

(Example〕 Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows the structure of a click-sensitive transparent switch according to an embodiment of the present invention. FIG. 2(a) is a plan view, and FIG. 2(b) is a sectional view taken along arrow AB.

In the figure, reference numeral 2 denotes a transparent film constituting the upper surface of the transparent switch, and a band-shaped transparent electrode (conductor) is formed on this transparent film 2 in the X-axis direction.

Reference numeral 4 denotes a transparent film constituting the lower surface of the transparent switch, and a band-shaped transparent electrode (conductor) is formed on this transparent film 4 in the Y-axis direction perpendicular to the transparent electrode 1.

These transparent films 2 and 4 are
They are bonded together with a spacer 6 in between, and a certain distance is maintained between the transparent electrode 1 and the transparent electrode 3 so that they do not come into contact with each other.

Further, as shown in the figure, a convex portion 5 having a predetermined bulge is formed in a portion of the transparent electrode 1 of the transparent film 2 that intersects with the transparent electrode 3 of the transparent film 4.

The transparent switch configured in this manner is placed on both display surfaces 7 of a CRT display device, liquid crystal display device, etc.
Display screen 7 at the intersection of the transparent electrode I and the transparent electrode 3
A key figure is displayed above. The operator manually operates the keys by pressing the part where the desired key figure is displayed.

At this time, due to the convex portions 5 formed on the transparent film 2,
Since there is a certain stroke before the transparent electrode 1 and the transparent electrode 3 come into contact, the operator can perceive a click feeling.

By the above operation, the transparent electrode 1 and the transparent electrode 3 are brought into contact and conductive, and the positional data of the conduction is transmitted to the control unit (not shown).
The pressed key can be detected in the same way as a key press on a keyboard.

Figure 3 shows an example of using the click-sensitive transparent switch as an actual input device. Figure 6 shows the case where the keys are arranged on a 5x4 x-y matrix. .

In the figure, the scan signal Sl is a signal supplied from a control section (not shown), and signals AO to A4 are sequentially activated and supplied to the transparent electrode 1 in the X direction while changing the phase.

Furthermore, a data output signal S2 (consisting of signals DO to D3) is output from the transparent electrode 3 in the Y direction in response to a press by the operator.

This data output signal S2 is sent to the control section and is used to detect a pressed key.

In addition, 5 is the above-mentioned convex part (intersecting part), and 7 is a display screen.

In the above configuration, for example, if one of the convex portions is pressed, the signal D is detected at the phase (timing) of the signal AO.
o becomes active. The control unit can know that the key indicated by K has been pressed by detecting the timing at which the signal DO becomes active.

In the above embodiment, a click-sensitive transparent switch is arranged on the entire surface of the display screen 7, and a convex portion 5 with a bulge is formed at the intersection, but if necessary, a part of the transparent switch may be arranged. The structure may be such that the convex portion is formed only on the surface.

Further, although the case where a CRT display device or a liquid crystal display device is used as the display screen 7 has been described, it goes without saying that display devices other than those described above may be used.

Further, in the above embodiment, a transparent switch is arranged on a display device, but an input device is constructed by placing a click-sensitive transparent switch according to the present invention on a board from which key figures are removed. You can also. In this case too,
The same actions and effects as in the above embodiment are achieved.

〔effect〕

As described in detail above, according to the present invention, it is possible to construct an inexpensive device that does not require a sounding means, and since there is no need to apply extra force, it is easy to operate and prevents deterioration of the device. We can provide sensitive transparent switches.
