<p>This invention aims at simplifying the manufacturing and assembling of a cassette and preventing the occurrence of creep in a cassette. A pair of pinch rollers (118, 119) for guiding a magnetic tape (T) are provided movably in an opening (75) for cassette of a casing (71), and the roller shafts (124, 125) supporting these pinch rollers (118, 119) rotatably are supported at both end portions thereof, these roller shafts (124, 125) being provided around their intermediate portions with receiving portions (120b, 121b) which retain the pinch rollers (118, 119) swingably. Accordingly, the pinch rollers (118, 119) are automatically aligned with respect to the roller shafts (124, 125) by the receiving portions (120b, 121b). Moreover, this enables the dimensional accuracy and mounting accuracy of the constituent parts to be moderated, while limiting the flexure of the roller shafts, which is ascribable to the capstans pressure-contacting the same.</p> |
