Abstract

PURPOSE: To eliminate the labor for performing programming newly after temporarily releasing the timer action by enabling the production of the control signal based on the coincidence detection of the contents of a counter and a memory means to be prohibited by a mask switch.
CONSTITUTION: The contents of a counter to which the input signal of a reference frequency is supplied and becomes the content corresponding to the current time and a sleeve counter 2 are supplied to a coincidence detection circuit 15, the coincidence detection output whereof is then supplied as a reset input to a flip-flop 19, acting as a sleeve mode. The contents of the counter 1 and alarm counter 3 are supplied to a coincidence detection circuit 16, the coicidence output whereof is supplied as a set input to the flip-flop 19, whereby alarm action is accomplidhed. To eliminate the need for alarm temporarily in the alarm mode, a mask switch 24C is turned ON, then the flip-flop 19 is not set, in which case the contents of the alarm counter 3 are not changed at all.
