Abstract
An apparatus for automatically reads a mode of a capstan reproducing speed by counting pulse signals generated from a capstan motor. This apparatus uses a pulse generator for generating pulse signals and, a frequency multiplier for doubling the capstan frequency generator signals. A counter circuit is used for counting output pulse signals of the frequency multiplier, and a gate processing circuit outputs three different reproducing speed discrimination control pulse signals in response to the signals counted by the counter circuit. A detection error compensating circuit outputs an Extended playing mode discrimination signal and a Long Playing mode discrimination signal from a reproducing speed discrimination control signal of the gate processing circuit by being driven by the pulse signals of the pulse generator. A Standard Playing mode discrimination signal is outputted by a logic combination from output signals of the detection error compensating circuit.
