<p>A tape recording and/or reproducing apparatus of the type having a tape guide drum with a circumferential slot through which at least one rotary transducer projects for recording and/or reproducing signals on a tape running against the periphery of the drum in a path which extends about at least a portion of such periphery; is provided with a tape guide assembly which includes a rigid guide, for example, constituted by an axially facing shoulder on the drum, engageable by the lower longitudinal edge of the tape for establishing the direction and location of the tape path, and resilient guide elements mounted on the drum so as to act yieldably against the upper longitudinal edge of the tape for holding the latter against the rigid guide while accommodating variations and changes in the width of the tape. In disclosed embodiments, each of the resilient guide elements is constituted by a length of spring wire bent to a U-shaped configuration to provide an anchoring end portion adjustably secured in a respective first radial bore of the drum, a contact end portion engageable with the upper edge of the tape and being movable in a respective second radial bore of the drum, and an intermediate portion extending along the drum periphery between the anchoring and contact end portions.</p> |
