Abstract
PURPOSE: To add accuracy to reduction of a processing time by adding a fixed- time rewind operation when signals on a magnetic tape are selected by a fast-feeding operation and are reproduced automatically and making it possible to reproduce the information part from the beginning.
CONSTITUTION: If no signal is inputted from tape 9 to reproducing head 10 for a fixed time at a reproducing operation time, transistor TrT4 is non-conductive, and capacitor C2 is charged; and when this charging advances by a prescribed quantity, TrT5 becomes conductive. Then, the output of NAND gate N2 is inverted from level "0" to level "1", and therefore, TrT2 becomes conductive, and relay 6 is operated, and the device starts the fast-feeding operation. When head 10 detects signals under this state, these signals are amplified by amplifier 11 and are rectified by rectifier 12 to make TrT4 and TrT5 conductive and non-conductive respectively. Then, monostable multivibrator 14 is operated to generate an L-level output. The output of NAND gate N3 is H-level for a fixed time by this output, and during this time, TrT3 and relay 7 are operated successively to execute a rewind operation. After completion of this rewind operation, the reproducing operation is restarted.
