Claims

[Scope of utility model registration request]

A pair of reel stands, each of which engages with a hub reel of a cassette tape, are swingably provided and biased according to the rotational direction of the reno and remotor, and are connected to the reel stand on the winding side of the pair of reel stands. In a tape travel control device driven by a single reel motor capable of forward and reverse rotation via an intermediate idler, in response to a transition command from tape high-speed travel mode to any other travel mode including stop mode, a first timer that is activated and measures the i-th set time; a first pause control device that suspends the supply of driving power to the reel motor while the first timer measures time; The operation of the control means is completed or the first
a second timer that is activated in response to the completion of timekeeping by the timer and measures a second set time; a reverse rotation control means for supplying driving power in the rotational direction; and a reverse rotation control means that functions only when the transition command is not a transition command to a stop mode, and the operation of the reverse rotation control means is completed or the time measurement of the second time measurement means is completed. a third timer that is activated in response to the third set time and measures a third set time; and a second pause control means that suspends the supply of drive power to the reel motor while the third timer is measuring time. Rotational speed detection means for detecting rotational speed information of each of the pair of reel stands, and an operation for calculating the winding amount of the tape based on the rotational speeds of both the reel stands obtained by the rotational speed detection means. and the first and second clocks in the first and second timekeeping means according to the calculation result of the calculation means.
1. A tape running control device comprising: control means for changing and controlling a set time.
