ABSTRACT:
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 spaced apart resilient guide elements extending radially on the top surface of the drum and being secured to the latter, at their inner ends, while the free end portions of the resilient guide elements project beyond the guide drum periphery and act yieldably against the upper longitudinal edge of the tape for holding the latter against the rigid guide with each resilient guide element flexing in a plane substantially at right angles to the tape path for accommodating variations and changes in the tape width. Further, a device is provided which acts simultaneously on all of the resilient guide elements for adjustably limiting the movements thereof in the direction toward the tape path.
