Abstract

PURPOSE:To allow a guide roller to operate as an impedance roller upon occasion by providing the guide roller with a means engaging and disengaging a flywheel. CONSTITUTION:In recording and playback mode, an electromagnetic brake 7 fixed on a housing 1 is not in operation and a flywheel 4 supported by bearings 5a and 5b is pressed against the cork plate 6 of a disk 5 fixed on a rotating shaft 3 by a spring 9 between bearings 2b and 5a. The flywheel 4, therefore, rotates together with the rotating shaft 3 in one body and the rotating shaft 3 serves as an impedance roller. In fast-forward or rewind mode, an armature plate is attracted to a brake stator 7a by the energizing of an electromagnetic brake driving circuit to separate the flywheel 4 from the disk 5, and the rotating shaft 3 operates as a mere guide roller.
