Abstract
PURPOSE: To eliminate fruitless electric power consumption while making recording, etc., convenience by holding the display of count contents for a certain time by driving a display circuit for the certain time even when a tape recorder is placed in stop mode.
CONSTITUTION: The output of up/down counter 13 is displayed by display element 28 by way of latch circuit 27 and decoder-driver 26. When an operation mode change-over switch is switched to the stop mode, main switch 21 is switched off and the output of OR gate 17 falls. Synchronizing with this fall, trigger circuit 18 and monostable multivibrator 19 are driven to output pulses K of constant time width. In the continuation of pulses K, constant-voltage circuit 24 and boasting circuit 25 keep on driving decoder-driver 26 to hold the display of count contents for a certain time. Consequently, the display part is being driven continuously even in stop mode. Consequently, the electric power consumption of the display part can be reduced in comparison with that of a conventional way.
