ABSTRACT:
An electronic counter circuit counts pulse signals generated according to the rotation of a takeup shaft of a tape recorder to display a value corresponding to a run of a tape. In the electronic counter circuit, a power supply voltage is supplied to a counter through a voltage stabilizing circuit and a switching circuit is connected between the voltage stabilizing circuit and a power supply for electrically interrupting power to the voltage stabilizing circuit a predetermined time after a motor is electrically interrupted to cause the rotation of the takeup shaft to be stopped.
