Abstract

PURPOSE: To perform leading-in of tape without giving effect to running, by making fast feed the tape in required number of times toward forward and reverse, through giving greater time constant of non-signal detection means.
CONSTITUTION: The non-signal section immediately before the desired address of the fast feed tape 1 is detected with the non-signal voltage transformation means 4 and the output of the level detection means 5 is inverted, then the pulse 2 produced with the single pulse generation means 6 is counted at the count means 8 of the tape running control signal generation means 19. Further, when the output of the means 5 is again inverted with the signal from the address K, the detection time constant of the means is greater with the songle pulse producing means 7 and Ff 11, the reverse direction fast feed control signal is produced via the NAND gates 12 and 13 to which the high level pulse of the means 7 and the control signal of high and low level at fast feed are fed, the tape in over running is tentatively stopped and fast-fed toward reverse. At the non-signal of tentative stop, the output of the means 5 is not inverted because the time constant of the means 4 is greater. When the number of times of forward and reverse counted at the means 8 reaches a given value, reproducing state is caused and correct leading-in is made without being affected with over running.
