PURPOSE: To prevent the up-down shift of a magnetic tape, by turning a take- up reel driving disk or a supply reel driving disk at an optional position between the stop position and the loading end position, and then actuating a pull-out post.
CONSTITUTION: A control lever 30 is shifted toward an arrow K by a motor 32 when a control lever 21 is at a stop position. Thus the pins 24 and 25 ride on the cam part of the lever 30, and then main brakes 22 and 23 are detached from a supply reel drive disk 4 and a take-up reel drive disk 5 respectively. Then an idler pulley 27 is pressed to a motor pulley 35 which is previously turned by energizing a spring 34. In this case, the direction of the pulley 27 is decided by the turning direction of the pulley 35.
