<p>PURPOSE:To obtain the keyboard, which can reduce burden on the eyes of an operator, by confirming an input operation in voice and showing a character to be inputted from the keyboard to the operator according in voice. CONSTITUTION:This system reports the information of inputted switches to the operator in voice from a voice output circuit 3 in the case of key input operations. The character to be inputted is informed of the operator in voice, and the character outputting the voice is inputted by the operation of the operator. Namely, a microcomputer 1 is connected so as to such a key matrix 2 connecting the plural key switches in the shape of a matrix, and the voice output circuit 3 is connected to the microcomputer 1. The microcomputer 1 scans the key matrix 2 and when the key push-down of the operator is detected, the microcomputer 1 reports the information of the pushed-down key to the operator with the voice and generates codes by operating the sound output circuit 3. Afterwards, this operation is repeated.</p> |
