In a timer device, the counter thereof counts the number of the pulses of a pulse signal input from an external apparatus up to a count initial value to output a count ending signal at the time of the end of the counting, and the control signal generator thereof generates a signal for controlling the external apparatus on the count ending signal output from the counter, and further the count operation controller thereof controls the count operation of the counter on a state change signal indicating the change of the state of the external apparatus. Thereby, the timer device can execute extensive processing by means of few counters.
