PURPOSE:To raise operability of a key in case of repeating the same processing, by outputting an inputted code and also storing it in a storage part until a prescribed code is inputted, and outputting the code stored in the storage part when the prescribed code is inputted again. CONSTITUTION:In case when a key input is executed to a controlling circuit 31 from key switches K2-Kn by a key operation, the circuit 31 outputs a key- inputted code to the outside as a signal (a) unless there is a key input from a key switch GK, and also stores it in a storage part 2. When a code is inputted from the key switch GK, the circuit 31 sends a signal (d) to an auxiliary circuit 32 if a signal (b) inputted from the circuit 32 is in a reset state, and sets the signal (b) to a set state. Subsequently, the circuit 31 outputs the signal (a) and stores it in the storage part 2. In this way, a repeated instruction of the same key input can be executed by the key switch GK. |
