Abstract

PROBLEM TO BE SOLVED: To dissolve defects that use is difficult, a cost is high and a wide space is required by providing an operation instruction character for a healthy user and operation instruction Braille for a blind user on a finger pressed surface. SOLUTION: The operation instruction character for the healthy operetor and the operation instruction Braille for the blind user the provided on the finger pressed surface. This device is used as the dial button 2 of a portable telephone 1 for instance, and the operation instruction character 4 for the healthy user and the operation instruction Braille 5 for the blind user the provided on a finger pressed peak surface 3. In this case, for instance, it is executed by turning the Braille 5 to a recessed shape or constituting an operation button such as the dial button 2 of a transparent plastic material, projectingly (recessedly) providing the operation instruction Braille 5 for the blind user on the outer surface and providing the operation instruction character 4 for the healthy user on an inner surface or providing the operation instruction character 4 for the healthy user and the operation instruction Braille 5 for the blind user as overlapped arrangement instead of side-by-side arrangement.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation button for a normal person and a blind person, such as a dial button of a telephone, a keyboard of a personal computer / word processor, a key of a calculator, a button for indicating a floor number of an elevator, a switching button for turning on / off, and the like. Related to the device.

[0002]

2. Description of the Related Art A conventional operation button device of this type is provided with operation instruction characters for a healthy person on the top surface of an operation button main body and braille for operation instruction for a blind person on the operation button main body. Or a form provided by attaching it to a place surrounding the same, or a form dedicated to a healthy person and a structure dedicated to a blind person, which are separately provided and used.

[0003]

The type described in the above-mentioned prior art is particularly difficult for the blind because the position of the operating character for the blind is relatively far from the position of the operating character for the healthy person. Is difficult to use, and in manufacturing it was configured separately for healthy and blind people, so it was not only expensive as a result, but also required a relatively large space for installation etc. Had problems.

An object of the present invention is to provide a novel operation button device which is extremely effective in solving the above problems.

[0005]

Means for Solving the Problems In order to achieve the above object, an operation button device for a normal person / blind person according to the present invention comprises:
An operation instruction character for a healthy person and an operation instruction braille for a blind person are provided on the pressing surface of the finger.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIG. 1 is used as a dial button 2 of a mobile phone 1, and includes an operation instruction character 4 for a healthy person and an operation instruction for a blind person on a top surface 3 of a finger. Braille 5 is provided.

According to the present invention, for example, the Braille 5 is made concave or the operation buttons such as the dial buttons 2 are made of a transparent plastic material, and the operation instruction Braille 5 for the blind is provided on the outer surface thereof.
And provided on the inner surface with operation instruction characters 4 for a healthy person (see FIG. 3), or as shown in FIG. 1, operation instruction characters 4 for a healthy person and operation instructions for a blind person. The present invention can be implemented by providing the characters 5 as a weight arrangement instead of the side-by-side arrangement, or by illuminating the backlight from the inside. In addition, the characters for operation instruction of a healthy person include a symbol and the like.

[0008] In the above case, there is an advantage that it is difficult to be stained. In such a case, a healthy person can be obtained by performing a contrivance such as performing printing on the wall surface of the mold in advance during the plastic molding of the operation button. It is easy to provide the operation instruction characters 4 for use and the operation instruction characters 5 for the blind all at once, which is convenient for improving productivity and reducing costs.
In such a case, the area for providing the operation instruction character 4 for a healthy person and the operation instruction character 4 for a blind person can be reduced by half, which is advantageous for miniaturization. Both characters 4 and 5 are easy to see and are good.

[0009]

As described above, the operation button device according to the present invention is characterized in that operation instruction characters for healthy persons and operation instruction braille for blind persons are provided on the pressing surface of the finger as described above. So, the disadvantages that are difficult to use as described in the prior art,
The disadvantages that are expensive and that require a large space can be eliminated, and the intended effect can be completely achieved.
