Abstract

PURPOSE:To contain magnetic tape in cassette without slant of magnetic tape, by drawing out or returning the magnetic tape leading out means outside the magnetic tape cassette through the revolution of a motor bidirectionally. CONSTITUTION:Magnetic tape drawing out blocks 36, 40 which reciprocate between the 1st position enabling to draw out a magnetic tape 18 in a cassette 12 and the 2nd position in which the tape 18 is led out outside the cassette 12 and contacted with a magnetic head 62. In response to the signal of a revolution stop and detection means in which the revolution of a winding reel stand 10 stops, a pinch roller 94 is detached from a capstan 88 to stop the run of the tape 18 and a motor 70 is turned to be moved from the 2nd position to the 1st position for magnetic tape drawing out blocks 36 and 40. Further, the relation of equation I is obtained for the length (l) of the tape 18 led out outside the cassette 12, constant speed (v) of the tape 18, time (t) when the rotation stop detection means causes a signal from the stop of the winding reel stand, and length L of the tape wound by the reel stand drive means.
