Abstract

PURPOSE: To make possible making braking distance constant at the deceleration timing of tape by detecting the previous running conditions of magnetic tape and determining the deceleration time based on each time.
CONSTITUTION: A capstan motor control part counts the clock signals being inputted from its terminal (a) at a constant period with a counter 11 for time measurement, is connected with registers 12 thru 15 which hold deceleration time, stop time, acceleration time and constant speed running time in this counter 11, is connected to a register 16 which holds the tape speed from a capstan motor speed detection part and the respective registers 12 thru 15 and is constituted by a circuit 17 which operates the contents thereof and determines the deceleration time of the magnetic tape and a counter 18 which makes possible presetting of the output of the circuit 17 and determines the deceleration time. The control signal J thereof is supplied to a capstan driving part to control the capstan motor, whereby the runn- ing distance of the tape may be made constant.
