发明名称 INFORMATION RETRIEVAL DEVICE
摘要 PURPOSE:To compensat accurately the stop position of a frame picture on a screen, by controlling a feeding means so as to stop an information recording medium after being fed by a prescribed length when an operating means is operated after the end of retrieval. CONSTITUTION:In closing operating switch 100 or 101 to correct the stop position of the frame picture, a signal sets a flip-flop circuit 102 via an inverter V1 and a pulse signal is given from a one-shot multiibrator circuit 103. Thus, an AND gate A1 is opened and a motor M3 is driven via a motor driving circuit 104. An output of an inverter V3 goes to low level and brake solenoids SOL3, SOL2 are not activated. The film is fed, the motor M3 is stopped after a set time of the one-shot multivibrator circuit 103, the brake solenoids SOL3, SOL2 are activated via brake driving circuit 106, 107 and the film comes to a stop.
