Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a switch with a display device, which is used, for example, in automatic ticket vending machines, automatic vending machines, etc., and which has both a switch function and a display function.

[Conventional technology]

This type of switch with an indicator basically houses the indicator and switch in a case, and the internal switch can be operated by pressing a translucent operation cover provided on the front side of the indicator. It has a structure that operates. Further, the display can display the contents of the electrical signal applied from the outside.

Incidentally, in recent years, there has been a trend toward sharing automatic ticket vending machines and the like with visually impaired people and visually impaired people.

Conventionally, for example, as shown in FIG. This was achieved by pasting Braille-embossed tapes 4 with contents corresponding to the display contents of each switch 2 with an indicator on the upper part of the switch 2 with an indicator.

[The problem that the idea aims to solve]

However, in the above-mentioned switch, the display-equipped switch 2 and the corresponding Braille engraved tape 4 are separate, and when a large number of display-equipped switches 2 are arranged in several rows, the upper and lower display Because the distance between the switches 2 with the display is narrow, it is said that it is often the case that the Braille engraved tape 4 and the switch 2 with the display are mismatched (in particular, the upper and lower switches 2 with the display are operated incorrectly). There was a problem.

In addition, space must be secured for the Braille engraved tape 4, and furthermore, in order to reduce the number of erroneous operations, the distance between the upper and lower display switches 2 must be further increased, so a large space is required. Therefore, there was also the problem that the operation panel etc. became larger.

Therefore, the object of this invention is to solve the above-mentioned problems by improving a switch with an indicator.

[Means to solve the problem]

In order to achieve the above object, the switch with a display of this invention has a Braille symbol on a part of the front side of the operation cover, away from the front of the display, and the operation cover has a Braille symbol on a part of the front side of the operation cover. It is characterized by being able to rotate back and forth around a support shaft located at the rear.

In that case, a Braille stamping member on which Braille symbols are stamped may be removably attached to the operation cover.

Further, the operation cover may be removably fitted into the front part of the case.

[Effect]

According to the above-mentioned switch with a display, since the Braille symbol is provided on a part of the front side of the operation cover, that is, the Braille symbol and the operation cover are, so to speak, integrated, so that a visually impaired person can easily read the content of the Braille symbol. By pressing the operation cover with the confirmed hand, the switch with the display device can be operated.

Furthermore, since the Braille symbols are placed in front of the display, it is possible for people with good vision to visually recognize the contents displayed on the display without any problem.

What's more, the operation cover can be rotated back and forth around the support shaft at the rear of the Braille symbol, so when you touch the Braille symbol to check its content, the operation cover can be rotated back and forth. Even if a certain amount of pressing force is applied, the operation cover does not easily rotate, and therefore the possibility of erroneous operation while checking the content of Braille symbols is extremely reduced. Furthermore, when you want to operate a switch by pressing the operation cover, you only need to press a point a little away from the Braille symbol, and in this way a rotational force is generated, making it easier to operate. Therefore, it is possible to easily achieve both prevention of erroneous operation and good operability.

〔Example〕

FIG. 1 is a longitudinal sectional view showing a switch with an indicator according to an embodiment of the invention, and FIG. 2 is a front view of the switch with an indicator shown in FIG.

The switch 12 with an indicator of this embodiment has a reinforcing plate 16 wrapped with a single-sided conductor flexible printed circuit board 18 on both sides inside a case 14 made of an insulator. The flexible printed circuit board 18 is arranged substantially parallel to the rear surface of the case 14, and a portion of the flexible printed circuit board 18 is exposed from the rear surface of the case 14 for external connection. However, instead of using such reinforcing plate 16 and flexible printed circuit board 18, a fixed printed circuit board may be used and a portion thereof may be exposed from the side of case 14.

A display device 20 such as an LED display is attached to the front side of the printed circuit board 18 in the case 14 (on the left side in FIG. 1), and a switch such as a tact switch is attached to the rear side of the printed circuit board 18. 22 and its actuator 2.
21 is out to the rear.

The reason why the display 20 and the operation cover 24, which will be described later, are tilted upward in FIG. 1 is because the upper side in the figure is the upper side when the switch 12 with display is normally used, and the display on the display 20 is tilted upward. This is to make it easier to see diagonally from above, but it is not essential.

In the front part of the case 14, the case 14
It has two fitting pieces 243 that are rotatably and removably fitted to two protruding shafts 142 protruding inwardly from both the left and right sides of the As shown in A, a translucent operation cover 24 that can be rotated in the front-back direction is removably fitted. This operation cover 24 may be transparent or translucent, and may be detachable.

In addition, an elastic lever-like movable piece 26 that is bent in an inverted C-shape when viewed from the side is housed in the bottom of the case 14, and uses the support part 141 provided at the bottom of the case 14 as its fulcrum. , Using the long side end of the movable piece 26 as a point of emphasis, press or release it as shown in the arrow B in response to the pressing operation of the operating cover 24 as shown in the arrow A with the foot 241 extending from the operating cover 24. Accordingly, the actuator 221 of the switch 22 is moved in the direction of the arrow C by using the end of the short side of the movable piece 26 as the point of action.
The switch 22 is operated by pressing and releasing it as shown in FIG.

Furthermore, a recess 242 is provided in a part of the front side of the operation cover 24 away from the front of the display 20, and in this example, in front of the pivot shaft of the operation cover 24 as described above. A tape-shaped or plate-shaped Braille marking member 28 with a Braille symbol engraved therein is housed therein, and a removable frame-shaped marking cover 30 is placed over the Braille marking member 28.
8 is removably attached.

The contents of the Braille symbols on the Braille marking member 28 are made to correspond to the contents displayed on the display 20 when the switch with display 12 is actually used.

Therefore, according to such a switch 12 with a display, the Braille symbol and the operation cover 24 are integrated, so that if it is used in, for example, an automatic ticket vending machine or vending machine as described above, visual impairment may occur. The person can operate the switch with display 12 by pressing the operation cover 24 with the bottom part where the content of the Braille symbol has been confirmed. Therefore,
There is no fear that a visually impaired person will operate the switch by misunderstanding the correspondence between the Braille symbols and the switch.

Furthermore, as described above, since the Braille marking member 28 is kept away from the front of the display 20, it is possible for a visually impaired person to visually recognize the displayed content on the display 20 without any problem. Therefore, this switch 12 with an indicator is
Furthermore, automatic ticket vending machines and the like using this system can be shared by visually impaired people and visually impaired people.

In addition, since there is no need to separately provide Braille engraved tape or the like as in the past, there is no need for space.Moreover, even if multiple display switches 12 are placed close together, there is no risk of erroneous operation for the reasons mentioned above, so the spacing between the switches can be reduced. In particular, the vertical spacing can be reduced, and as a result, it is possible to save space on the operation panel, etc., and it is also possible to downsize equipment such as automatic ticket vending machines.

Moreover, the operation cover 24 has a supporting shaft (in this example, a protruding shaft 14) located at the rear of the Braille marking member 28.
2), so even if a slight pressing force is applied to the Braille marking member 28 when checking the contents of the Braille symbol by touching the Braille marking member 28, the supporting shaft will not move. Because it is located in front of the Braille symbol, almost no rotational force is generated, so the operation cover 24 does not easily rotate, and therefore, the possibility of erroneous operation while checking the contents of the Braille symbol is extremely reduced. Moreover, when you want to operate the switch 22 by pressing the operation cover 24, you only need to press a little below the Braille marking member 28.
In this way, rotational force is generated, making it easier to operate.

Suppose that the operating cover 24 is not rotatable around the pivot at the rear of the Braille symbol, but instead has a center of rotation at the rear of the end of the operating cover.
If Braille symbols are provided on such operation covers, there is a high possibility that the operation cover will rotate with a small amount of force while checking the contents of the Braille symbols, resulting in erroneous operation.If you try to avoid this, the spring pressure that pushes the operation cover back increases It is necessary to make the stroke stronger or make the stroke longer.
In this case, when you really want to operate the switch, you have to press it strongly or deeply, which causes a problem that the operability deteriorates. On the other hand, if the switch 12 with an indicator is used, it is possible to easily achieve both prevention of erroneous operation and good operability.

If the Braille marking member 28 is removably attached to the operation cover 24 as in the above embodiment, when changing the displayed content such as when changing charges, it is easy to change the Braille marking member 28. can correspond to

Alternatively, instead of doing so, the Braille marking member 28 may be pasted on the operation cover 24, or the Braille symbol may be displayed directly on the operation cover 24 itself, and even in that case, the operation cover 24 may be attached to the case as described above. If it is removably fitted into the front part of 14, the operation cover 2 can be used to change fees, etc.
This can be easily handled by simply replacing item 4.

Further, if the Braille marking member 28 is housed in the recess 242 provided in the operation cover 24 and covered with the marking cover 30 as in the above embodiment, the Braille marking member 28
Regardless of whether Braille 8 is simply stored in the recess 242 or pasted, it is preferable in terms of aesthetics and operability because there is no unnecessary protrusion on the surface of the operation cover 24, and it also prevents the Braille marking member 28 from being undesirably removed. This is preferable because it makes it difficult to peel off, but it is not essential.

[Effect of idea]

Since this invention is configured as described above, it has the following effects.

In other words, since Braille symbols are provided on a part of the front side of the operation cover, all you need to do is press the operation cover with your hand after confirming the contents of the Braille symbols, and this makes it easy for visually impaired people to correspond between the Braille symbols and the switch. There is no need to worry about accidentally operating it.

Furthermore, since the Braille symbols are placed in front of the display, they can be shared by both visually impaired and visually impaired people.

In addition, there is no need to separately install Braille engraved tape, etc. as in the past, so there is no need for space.Moreover, even if multiple switches with display devices are placed close together, there is no risk of erroneous operation for the reasons mentioned above, so the spacing between the switches can be reduced. As a result, it is possible to save space on the operation panel, etc., and it is also possible to downsize the device.

What's more, the operation cover can be rotated back and forth around the support shaft at the rear of the Braille symbol, so when you touch the Braille symbol to check its content, the operation cover can be rotated back and forth. Even if a certain amount of pressing force is applied, the operation cover does not easily rotate, and therefore the possibility of erroneous operation while checking the content of Braille symbols is extremely reduced. Furthermore, when you want to operate a switch by pressing the operation cover, you only need to press a point a little away from the Braille symbol, and in this way rotational force is generated, making it easier to operate. Therefore, it is possible to easily achieve both prevention of erroneous operation and good operability.

In addition, if a Braille engraved member with Braille symbols engraved on it is removably attached to the operation cover or the operation cover is removably fitted into the case, changes in the display content of the Braille symbol will This can be easily done by simply converting.
