Abstract

PURPOSE: To ensure a control via a microcomputer so that a magnetic tape travels at a certain high speed when an automatic head leading is given to the magnetic tape.
CONSTITUTION: When the music selection switch S2 is made off, the power supply voltage of the DC power supply terminal +B is applied to the 3rd input terminal I3 of the microcomputer CPU via the 2nd resistance R2. Thus the microcomputer has no operation. Then an automatic head leading operation is performed to give a high-speedtravelling to the magnetic tape with the terminal I3 earthed. Thus the computer CPU works to count the pulses of the rotary shaft of the tape send-out side reel which are supplied to the 1st input terminal I1 from the rotary detector TD in a certain time (t) of the output pulse interval of the reference signal generator RSG to be supplied to the 2nd input terminal I2. The rotating speed of the drive motor M lowers down stepwise in accordance with the output signal of the microcomputer CPU to secure the tape travelling at a constant speed.
