Abstract
PURPOSE:To record a sound on a tape by recording a signal for program control on the 2nd track side of a projector, by driving a tape recorder according to the recorded signal, and by placing the 1st track side in a recording state. CONSTITUTION:An input signal from an MIC (microphone) terminal 61a or AUX input terminal 39 is inputted to a recording and reproducing head 30 through amplifiers 60' and 61' to be recorded on the 1st track. When an operation button is pushed for the execution of a program over a look at a screen, a signal from 1kHz oscillator 51 is recorded on the 2nd track. Then, when a reproduction button on a tape recorder is pushed and an operation knob ia placed at a sound position, a 1kHz reproduced sound from a recording and reproducing head 30' is inputted via a filter 40 and an amplifier 41 to a Schmitt circuit 42, whose output operates a relay driving circuit 43 to drive a relay circuit 44, and then the tape recorder is drive to reproduce a sound on a tape.
