Abstract

PURPOSE:To enable the tentative selection to the time display on the way of calculation without increasing power consumption, by clearing the register via the timer. CONSTITUTION:When the switch 7 of the switch circuit C is closed, the selection unit 6 is selected with the set output of T-type FF9, and the count value of the time counter 3 of the watch circuit A is displayed on the display section 5 as the time in place of the content of the register 18 storing the result of count of the calculation circuit B. Simultaneously, D-type FF10 of the count circuit D is set with the closing of the switch 7, the AND gate 11 is opened, and when the timer 12 elapses the timer time, the register 18 is not cleared until the RS-type FF13 is reset with the inversion of output. Accordingly, when the switch 7 is reopened, within the time limited with the timer 12, the result of calculation is displayed on the display section 5, and the register is cleared after the timer time elapsed and the time can be known even on the way of calculation without increasing the power consumption.
