ABSTRACT:
In a tape recorder including a circuit for generating a pulse signal corresponding to an amount of tape travel, an electronic counter circuit is provided which includes a counter for counting pulses and a display section for displaying a count value. The electronic counter circuit further includes a memory for receiving voltage at all times from a power supply and storing a count value and a control section adapted to maintain the energization of the display section for a predetermined time period after the operation of the tape recorder is stopped and to stop the energization of the display section thereafter, while inhibiting the resetting of the counter.
