<p>PURPOSE:To run a magnetic tape stably at a high speed even when its amount is small by providing a wall surface material between the intake of a driving part and a slide piece on a side wall of a bin where the magnetic tape is stored, and moving the slide piece and varying the storage amount of the tape. CONSTITUTION:The flexible wall surface material 72 is provided between the partition wall 49 of the intake of the driving part and the slide piece 76 provided on the side wall of the bin 16 where the magnetic tape is stored. The magnetic tape 2 has a route shown in a figure and is run at a high speed by a capstan 4, pinch rollers 5 and 6, motor 13, etc., to preform its reproduction by reproducing heads 14 and 15, but when the amount of the tape is small, said slide piece 76 is moved according to the amount of the tape to feed the tape 2 into the intake along the wall surface material 72 all the time. Consequently, even when the tape amount is small, the inclination of the tape is prevented to perform the high-speed stable run.</p> |
