Abstract
PURPOSE: To provide a timer apparatus of easy programming controlling load after the set time by counting the pulse number of stable frequencies with a counter such as shift register or the like and controlling timer operation when the count value coincides with the set value.
CONSTITUTION: When a commercial power source 5 is supplied to a pulse oscillator 1, clock pulses are stably generated at each specified fixed time by way of the oscillation circuit 2 shaping waveforms with rectifier, smmothing circuit, etc., frequency divider 3 and counter 4 of the oscillator 1. The pulses are counted with a counter 6 such as shift register or the like in which the pulse number has beforenand been set according to the set time by a setter 7 and when the count value concides with the set value, that time is displayed in a display device 10 and at the same time the coincidence signal becomes a control signal which in turn controls a timer load 9 through a control unit 8. Hence, the timer is controlled according to the elapsed time without storing the current time and set time, thus the timer apparatus of easy program controlling may be provided.
