置。A first display control switch for separating the reading of the state of a plurality of key switches connected in a matrix from the reading of the state of a key switch whose one end is connected to a column of the matrix and whose other end is a key switch. In a key switch output reading control device that performs display control for driving connected light emitting means in a time-sharing manner under control of a first display control switch, the connection point between the diode and the light emitting means is connected to the light emitting means via another diode. and means for setting a specific potential state in conjunction with the operation of the first display control switch, and checking whether or not there is a change in the key switch output state at every predetermined period during display control, and A key switch output reading control device characterized in that display control is stopped and the key switch output state is read only when a change in the output state is detected.
