Abstract

PURPOSE: To prevent needed data from being erased carelessly by clearing a memory according to the logical product of the output of one coincidence circuit and a reset signal, by making the other coincidence circuit discriminate week time information and day time information.
CONSTITUTION: When coincidence circuit CON2 finds a coincidence between day time information stored in memory R2 and present day time information DATA2, coincidence circuit CON2 is considered to generate an output at timing T2.TX. As a result, reset signal RSTK is applied to one-side terminals of AND gates AG7W AG9 at time T2.TX and in accordance with the logical sum of it and timing signals T1WT3, a signal of [1] is outputted from gate AG8 while one shot OS2 cycles once. The contents of memory K2 are all "0" in consequence. Further, signal RSTK resets the alarming of buzzer-tone generating circuit OUT. On the other hand, when coincidence circuit CON1 detects week time information stored in memory R1 agreeing with present week time information DATA1, circuit OUT is driven at time T1.TX.
