Abstract

PURPOSE: To switch automatically the tape speed and the reproducing equalizer, by recording the automatic switching signal of a fixed frequency onto the tape at the recording time and by detecting this signal to switch the revolving speed of the tape driving motor at the reproducing time.
CONSTITUTION: At the recording time, switches S1 and S2 are connected to contact M and a desired speed respectively, and the sound recording signal is recorded after the automatic switching signal is recorded by the operation of switch S3. At the reproducing time, when switches S1 and S4 are switched to automatic side (A), transistor Q2 of the bistable multivibrator is nonconductive, and automatic switching detecting circuit 11 is held in the tape speed (v) side. For reproducing of the tape of recording speed 2v, the tape is reproduced in speed (v), and detecting circuits D1 and D2 are operated, and transistor Q2 becomes conductive, and the circuit is switched to the speed 2v side. If the tape of speed (v) is reproduced in speed 2v, the switching signal is generated by filters LF1 and LF2.
