Device for sending and receiving a message
摘要:
The invention concerns device for transmitting and receiving a message by means of the tactile sensation. By means of keys (2), a code corresponding to one character is formed at a time, which code is converted by the device into an electric signal. The electric signals can be stored in a tape recorder (15), transmitted via a modem (6) into the telecommunication network, or be converted by means of a typewriter (4) into inkprint. Correspondingly, electric signals coming from these peripheral devices can be coded as a mark on feeling keys (3). The device is above all intended as means of conversation and study for deaf-blind persons.
