QUICK TRAVERSE/QUICK STOP CIRCUIT OF 8-TRACK PLAYER

摘要

PURPOSE:To reduce overrun at the transfer from quick traverse to stop without complexing the constitution of the titled circuit by turning a switch when a motor quick traverse signal is turned off to brake the motor by itself. CONSTITUTION:If an input signal to a terminal (a) is turned to the low level by a stop instruction or the like turning off a motor quick traverse signal when an input signal to a terminal port is at the low level, a TRQ4 is turned off and a motor M is released from a control by the TRQ3 side, TRs Q5, Q6 are turned off. Consequently, a relay RL1 is disconnected, relay contacts 5, 6 are turned to the NC side and the motor M is shorted, provided with a dynamo function and braked by itself. Thus, overrun due to the inertia force of a fly-wheel is reduced at the transfer from fast feed to stop without complexing the constitution.
