DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

The word processor according to this embodiment is configured to display data input from a keyboard 1 via a control unit 2 on a display 3 or to print data using a printer 4.

The keyboard 1 is used to input data corresponding to key inputs, and a plurality of keys are provided on the keyboard body (not shown) so that they can be pressed and returned to normal. In Figure 2,
One key 5 among the above keys is shown, and this key 5
, normal characters 6 such as alphabets and katakana are displayed, and Braille 7 corresponding to these characters 6 are displayed. The Braille 7 is made up of a plurality of protrusions that protrude upward from the surface of the key 5, so that even people with visual disabilities can easily identify what each key corresponds to. It has become.

[0011] If the target is only visually impaired people, the normal characters 6 are not necessary and only the Braille characters 7 may be displayed.

The control section 2 controls the display 3 and printer 4 based on input data from the keyboard 1, and includes a code conversion section 8. The code conversion section 8 inputs a character code corresponding to the data inputted on the keyboard 1, converts it into Braille data, and sends this to the display 3. Further, the control section 2 sends a character code corresponding to the above data to the printer 4.

As shown in FIG. 3, the display 3 has a touch plate 9, which has conductive terminals 10a, 11a formed on the surface of a ground plate 9a whose surface side is made of a conductor. By arranging the Braille characters 11a at desired positions, an array of Braille characters 10 and 11 is constructed. In order to be insulated from the ground plate 9a, each of these terminals 10a, 11a is covered with an insulator (not shown) at the surrounding portion that contacts the ground plate 9a, and only the upper end portion that touches the fingertip is conductive. There is. Further, the other end side of each terminal 10a, 11a is connected to a power supply that applies a voltage (not shown) via conductive wires 10b, 11b.

When the display 3 receives Braille data from the control section 2, it applies a voltage to the terminals 10a, 11a of the touch panel 9, which correspond to the Braille data, via the conductive wires 10b, 11b. At this time, if the terminal to which the voltage is applied is touched with a finger, the terminals 10a, 10b and the ground plate 9a will be short-circuited through the finger, and the finger will be stimulated by the current caused by the short-circuit. Since this stimulation occurs at the terminal, it feels similar to the protrusions of Braille.

[0015] In order to enable people with normal vision to easily create sentences for people with visual impairments, the display 3 is equipped with a display section such as a cathode ray tube or liquid crystal, so that normal characters can be written. It may also be displayed. In this case, the character code corresponding to the data input using the keyboard 1 may be sent from the control section 2 to the display section. In this way, a person with normal vision who has no knowledge of Braille can print Braille on the printer 4 while looking at the display section of the display 3.

As shown in FIG. 4, the printer 4 includes a print head 13 and a platen 15.
A Braille puncher 14 is attached to the platen 15 side so that it can move forward and backward. The Braille puncher 14 has a longer stroke than that of a conventional printer, and the platen 15 is made of a soft material, so that the Braille puncher 14 punches Braille protrusions on the paper 16 sandwiched between the print head 13 and the platen 15. It is now possible to do so.

The printer 4 also has a code conversion section 12, which converts the character code sent from the control section 2 into Braille data, and as described above, prints Braille protrusions on the paper 16. Launch.

The printer 4 may be capable of printing ordinary characters in addition to printing Braille projections. At this time, these functions may be selected based on input from the keyboard 1. In this way, a visually impaired person can print normal characters by touching the touch board 9, and a person with normal vision can print letters.
Document creation can be done easily.

As described above, according to the above embodiment, by inputting the key 5 on which Braille is displayed, data corresponding to this key 5 is input to the control unit 2, and the character code corresponding to this data is converted into a code. The data is converted into Braille data in the section 8, sent to the display 3, and a voltage is applied to the terminal of the touch panel 9 that corresponds to the Braille data. The data is also sent to the printer 4, and the code converter 12 converts the character code corresponding to the data into Braille data, and the printer 4 emits the Braille data onto the paper 16. This allows even visually impaired people to use word processors. Furthermore, as mentioned above, the keys 7 of the keyboard 1 can be used to display normal characters and braille corresponding to these characters, and the display 3 can be equipped with a display section such as a cathode ray tube or liquid crystal display to display normal characters. Ba,
It is also possible for people with normal vision to create sentences for people with visual impairments.

[0020]

As described above, according to the present invention according to claim 1, by inputting a key having Braille characters, data corresponding to this key is inputted, a voltage is applied to the terminal of the touch board, and the above-mentioned Since Braille characters corresponding to the data are printed on the paper by the printer, even visually impaired people can easily use the word processor. Further, according to the present invention according to claim 2, data corresponding to the key is input by inputting a key displaying a character, etc. and Braille corresponding to the character, etc., and a character code corresponding to the data is displayed on the display. At the same time, the character code corresponding to the data is converted to Braille data, a voltage is applied to the terminal of the touch panel corresponding to the Braille data, and the character code corresponding to the data is transmitted to the printer, This character code is converted to Braille data, and the Braille is printed onto paper by a printer, making it easy for people with visual impairments to use, and for people with normal vision to write text to visually impaired people.
