Abstract

PURPOSE: To secure the agreement of the speed between the tape and the capstan when the pressure action of the pinch roller completes through an automatic setting of the delay time by detecting the tape speed and the acceleration of the tape speed at that time point or the tape winding diameter of the reel.
CONSTITUTION: For the magnetic tape device incorporating pinch roller 7 and capstan 6, the following means are provided. That is, pinch roller driving means 17 which presses roller 7 to capstan 6; press action signal delay means 14 which gives a delay to the press action signal to actuate means 17; and delay time control means 16 incorporating acceleration detection means 15 to detect the acceleation of tape 3 in order to vary the delay time of means 14 so that the agreement may be secured for the speed between tape 3 and capstan 6 at the press time of roller 7 when the tape is running for reproduction or recording.
