PURPOSE:To simplify the constitution of a driving circuit which drives plural recording and reproducing devices successively or in parallel, by constituting the driving circuit by an electric coupling system which incorporates plunger. CONSTITUTION:When a simultaneous start switch S2 is turned off and a successive start switch S1 is turned on, the reproduction by the 1st recording and reproducing device with a pause switch S3 to be turned off is carried out. When a playback switch S5 is turned off on said reproduction, a current flows through the switch S5 to turn on a diode D, and a transistor Q1 is turned on. Consequently, a plunger P2 is energized to turn off a pause switch S4 for the 2nd recording and reproducing device, and reproduction is carried out successively by resetting the pause mode. The 1st and the 2nd recording and reproducing devices, etc., are processed in simultaneous parallel reproducing operation similarly, thereby simplifying the constitution of a driving circuit for plural recording and reproducing devices of an electric coupling system which incorporates plunger. |
