JPH04263353A - Desk-top calculator for visually handicapped person - Google Patents

Abstract

PURPOSE:To provide a desk-top calculator with which the visually handicapped persons can confirm the operations through the tactual senses. CONSTITUTION:A braille printer 13 contains the braille points on the surfaces of the input keys 12 of a desk-top calculator main body 11 and outputs these braille points for the output display. Then the input numerical value and result are outputted onto a printer form 14 in the braille points.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desktop calculator for visually impaired people, and more particularly, to a calculator that can be operated by a visually impaired person and allows him or her to check input results and the like.

0002

2. Description of the Related Art FIG. 3 is a perspective view of a conventional desktop computer. In a conventional desktop calculator, numbers, operators, etc. are displayed above input keys 1, and all outputs are visually confirmed using a liquid crystal display 2.

0003

However, the above-mentioned conventional desktop calculator has a problem in that it cannot be used by people with a handicap such as visual impairment.

The present invention has been made to solve these conventional problems, and an object of the present invention is to provide an excellent desktop calculator for visually impaired people whose operation can be confirmed by tactile sensation.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention adds Braille to the surface of the input keys so that numbers, operators, etc. on the input keys can be seen, and also attaches braille to the output printer. The input keys and results are output in Braille.

[0006]

[Operation] Therefore, according to the present invention, by displaying input keys such as numbers and operators and the output of a printer in Braille, the input keys and results can be confirmed by touch, and visually impaired people can do so by themselves. It has the effect of being able to operate a desktop calculator.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of an embodiment of the present invention. In FIG. 1, reference numeral 11 is a desktop computer main body, which is equipped with a microcomputer inside. Reference numeral 12 indicates input keys, and Braille characters corresponding to respective numbers and operators are engraved on the surface of each input key 12. Reference numeral 13 denotes a Braille printer, which is driven by the output of a microcomputer provided inside the desk calculator main body 11 to print Braille characters on printer paper 14.

Next, the operation of the above embodiment will be explained. In the above embodiment, when the input key 12 is pressed while checking the Braille characters on its surface with the fingertip, the Braille printer 13 displays Braille characters on the printer paper 14 corresponding to the numerical value and operator of the input key. This allows the operator to tactilely confirm the entered key values and operators.

[0009] Now, from the input key 12, numbers "2, 4, 5" are input.
” and the operator “+”, Braille letters corresponding to “2, 4, 5, +” are output vertically on the left side of the printer paper 14. This is shown in a normal visual representation. is figure 2
This is (a). The numerical value input in this way is determined at the stage when the operator is input. In this case, “245+
” is confirmed and displayed.

Similarly, (b) in FIG. 2 shows "29*17=4
This is an example of calculation for "93". Numbers, operators, and numbers are input, and the result is output after "=" is input.

As described above, according to the above embodiment, all the pressed input keys 12 are outputted in Braille on the printer paper 14 by the Braille printer 13, so that they can be confirmed by the sense of touch, and one visually impaired person can It has the advantage of being able to operate a desk calculator.

Although the above embodiment is an example in which a Braille printer is installed in place of a conventional liquid crystal display, it is possible to have both a Braille printer and a liquid crystal display so that both visually impaired and able-bodied people can use it. may be configured.

[0013]

[Effects of the Invention] As is clear from the above embodiments, the present invention allows a visually impaired person to operate a desk calculator by himself, since input keys, input results, and calculation results can be confirmed by touch instead of sight. It has the advantage of being able to
