Abstract

PURPOSE:To shorten the key input operation, by changing input data due to key switches for every key display placed in accordance with the key switch, in the key input device through which many kinds of input are possible. CONSTITUTION:A key label part A is formed to a shape like a belt, and the key code due to depression of a key switch on a keyboard B is sent to a reading part G through a signal line 1. When receiving this key code, the reading part G reads out the count value of a counter E, namely, the rotation position of the key label part A and outputs the key code and this rotation position to the external through a signal line 9. Consequently, an optical position of the key label part A is selected to input data.
