駆動回路。[Claims for Utility Model Registration] A capstan motor is started by a starting pulse based on an RF switching pulse, and a voltage opposite to that at the time of starting is applied to the capstan motor by a braking pulse based on a regeneration control signal. An intermittent drive circuit that brakes a capstan motor and controls the speed of the capstan motor during a period defined by the starting pulse and the braking pulse, comprising: a gate means for the regeneration control signal; and an FC of the capstan motor. means for generating an output for determining that the tape speed has reached a predetermined speed based on the signal; and means for creating a mask pulse corresponding to a period from the starting edge of the starting pulse to the determined output; An intermittent drive circuit characterized in that: is used as a control signal for the gate means.
