A device for winding a magnetic tape in good order on a tape cassette which has been repeatedly used in a telecasting station, is arranged at a mid portion between a pair of tape reels on an inner peripheral side of a running path of the magnetic tape pulled out from a tape cassette. The device has a touch roll abutted against the magnetic tape along the tape width for affording a constant contact pressure against the outer periphery of the tape reel as the tape is round, an arcuately-shaped roll arm member rotatably supporting the touch roll at its one end for facing the touch roll to the inside of the tape cassette, a roll arm supporting member for slidably supporting the roll arm member so that the touch roll is moved in the diametrical direction with respect to the tape reel, a plate on which the roll arm supporting member is assembled, and a roll arm driving mechanism for sliding the roll arm member along the roll arm supporting member. The roll arm supporting member is moved by the roll arm driving mechanism along the roll arm supporting member so that the line of force of the contact pressure applied to the magnetic tape taken up on the outer periphery of the tape reel traverses the center of rotation of the tape reel.

Device for winding magnetic tape of tape cassette in good order

A plurality of head tips Ra to Rd' and Pa to Pd' are disposed adjacently to each other in such a manner as to project from a peripheral surface of a rotary drum 2 by a predetermined length and at the same time the projecting lengths of the head tips Ra to Pd' are selected in such a way so that the surface pressures of a plurality of head tips Ra to Pd' on the magnetic tape 9 become uniform. Outer head tips are inclined by a predetermined angle and fixed. With such an arrangement, since the gap positions of the head tips become the center of tape contact against the magnetic tape 9, the surface pressures of the magnetic tape 9 against the head tips become substantially constant. If the surface pressures become constant, the head tips uniformly wear.
