ウンタ回路。 In a tape recorder in which a single counter display is shared by first and second tape drive mechanisms disposed in the same housing, whether a cassette is attached to each of the first and second tape drive mechanisms. first and second cassette detection switches for detecting the first and second cassette detection switches;
a reset circuit that outputs a reset pulse when it is detected that a cassette is attached to at least one of the second tape drive mechanisms;
first and second rotation detectors each detecting the rotation of a rotating body involved in tape running in the second tape drive mechanism section and generating rotation pulses; and one of the first and second rotation detectors. a selection circuit that outputs the rotation pulse as it is when it is generating a rotation pulse, but outputs the rotation pulse from the first rotation detector with priority when both of them are generating rotation pulses;
A counter for a tape recorder, comprising: a counter controller that resets the counting display of the counter display by a reset pulse from the reset circuit, and causes the counter display to display the count by a rotation pulse from the selection circuit. circuit.
