Claims

[Scope of utility model registration request]

In a tape recorder having a reverse function, a playing direction selecting means for selecting a playing direction, a fast forwarding operation specifying means for specifying a fast forwarding operation of the tape, a rewinding operation specifying means for specifying a rewinding operation of the tape, and a running direction of the tape. A running direction command cam that is movable between a forward direction command position and a reverse direction command position for commanding the direction; and a tape drive means that runs the tape at high speed in a tape running direction corresponding to the command result of the running direction command cam. , a cam position detection means for detecting the commanded position of the running direction command cam; a comparison means for comparing the designation results of the fast forward operation designation means and the rewind operation designation means with the detection results of the cam position detection means; cam driving means for displacing the running direction command cam until the comparison results match according to the comparison result of the comparison means; and the fast forward operation designation means and the rewind operation designation means according to the selection result of the performance direction selection means. A tape drive control device comprising a running direction reversing means for reversing the correspondence between the designation result of the running direction command cam and the command result of the running direction command cam.
