Abstract
PURPOSE:To enable assured step drive of a predetermined length of a magnetic tape or the like in a short time by so changing the output of a take-up reel step drive source as to ensure that the time required for advancing the tape by a certain distance may be constant. CONSTITUTION:The position of a tape 1, which is let off from a reel 3 and wound up around a step-driven take-up reel (capstan) 2, at time t1 is measured by counting the pulses from a tachometer; the excessive and deficient portions + or -DELTAx1 relative to the ideal value are fed to the terminal of an up-down counter UDC; and an enable terminal is fed with a signal when the absolute value of DELTAx1 has exceded an allowable value DELTAx0, to start counting. When the cases where the allowable value DELTAx0 is surpassed have successively accurred more than predetermined times, the output of a decoder DEC appears at a gain increase terminal or a gain decrease terminal, to change the gain of a motor amplifier 5 by one step, resetting the counter UDC. The measurement of the position x1 is conducted by the next step drive, and the normal take-up of the tape 1 is continued while the counter UDC is conducting the predetermained counting.
