Abstract

PURPOSE:To run a magnetic tape stably even if a capstan shaft which abuts on a pinch roller slants by slanting the capstan shaft when the magnetic tape is drawn out of a VHS tape cassette for the recording/reproduction processing of a magnetic head and then taken up around the take-up reel in the cassette through the pinch roller. CONSTITUTION:The magnetic tape 3 is drawn out of the VHS tape cassette 1 through its internal payoff roller to contact a cylinder 2 having magnetic heads, and the tape 3 after specific recording/reproduction processing is taken up around the take-up roller 15 in the cassette through the pinch roller 5 which abuts on the capstan shaft 4 provided on the surface of the cassette 1 and a tape run control post 14. In this constitution, even if the shaft 4 slants of if the tape 3 slacks, the tape is run stably and prevented from damaging by providing the capstan shaft 4 not in parallel to the surface of the cassette 1, but slantingly or by slanting a capstan fitting substrate which supports the shaft 4 by a specific angle previously.

After the magnetic tape 3 is driven by the capstan shaft 4 and the pinch roller 6, it is wound onto the take-up reel 16 via the tape travel regulating post 14, but the magnetic tape driving force of the pinch roller 6 decreases. As a result, upward sagging of the tape occurs between the capstan shaft 4 and the tape running regulating post 14, as shown in FIG. 5, making running unstable and tape damage likely to occur. The second feature of the present invention is that, as shown in FIG.
This can be solved by tilting as shown in 14a.
