Abstract
PURPOSE: To make information processing rapid by making it possible to select only a part, where signals are recorded, on a magnetic tape by a fast-feeding operation and reproduce it automatically.
CONSTITUTION: In case that reproducing switch 1 is turned on instantaneously to start a reproducing operation, transistor TrT4 is non-conductive and capacitor C2 is charged if signals are not inputted from tape 9 to reproducing head 10 for a prescribed time. When this charging advances by a prescribed quantity, TrT5 becomes conductive. Then, since the output of NAND gate N2 is inferted from level "0" to level "1", TrT2 is 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 circuit 12 to make TrT4 and TrT5 conductive and non-conductive respectively. Then, the output of NAND gate N2 become level "0", and this level-"0" output sets the output of NAND circuit N1 to level "1" through NAND gate circuit N3, and TrT1 is made conductive, and relay 5 is operated, thus restarting the reproducing operation.
