A pair of disk-shaped annular flanges is made of material firmer than that of a hollow cylindrical-shaped roller portion. The roller portion has an outer peripheral surface in which the flanges are mounted at opposite ends thereof. On press-fitting a pair of bearings in the roller portion, the flanges are retained by means of bearing flanges. The outer peripheral surface of the roller portion has a pair of flange guides, at opposite ends thereof, for guiding the flanges. The flange guide has a longitudinal length shorter than thickness of the flange. An adhesive agent may be filled in a gap formed among an end surface of the roller portion, the disk-shaped annular flange, and the bearing.

An ejection position detection mechanism has an arc-shaped plate, attached to a mode gear, having a plurality of detected elements provided at positions corresponding to a plurality of ejection positions of a cartridge, and a detection arrangement, disposed near to the arc-shaped plate, for detecting the plurality of detected elements. The arc-shaped plate consists of a shielding plate. The plurality of detected elements consist of an edge of the shielding plate and two slits formed on the shielding plate. The detecting arrangement consists of a photo-interrupter.

A pin retainer locks a leader pin during a movement of a pull-out assembly where the leader pin is coupled to a grabber between a grabber holder and a take-up reel. The pin retainer is urged toward a locking position by a spring. When the grabber comes close to a cartridge, a first releasing arm makes the pin retainer retract to a retracted position opposed to urging force of the spring.

A brush driving mechanism, which drives a cleaning brush from a retracted position to an operation position opposed to a magnetic head, has a main arm having a tip coupled to the cleaning brush through a shaft. A chassis has a chassis slit, in which the shaft is inserted, for allowing to move the cleaning brush from the retracted position to the operation position by operating the main arm. The chassis slit has a tip portion stops the shaft when the cleaning brush is put into the operation position to position the cleaning brush with respect to the magnetic head.

A retaining member for retaining a grabber has a positioning arrangement for fixing the grabber in place. The grabber has a rear surface having a pair of hollows at upper and lower end portions. The positioning arrangement has a retainer opposed to a front surface of the grabber on retaining the grabber and a pair of leaf springs opposed to the retainer with a space shorter than a thickness of the grabber. The pair of leaf springs is disposed apart from each other up and down. The pair of leaf springs has a pair of projections engaged with the pair of hollows. The pair of hollows is disposed the outside of a tape winding portion where a magnetic tape is wound.

A clutch member coupling a first gear with a second gear with a play has a first clutch gear engaged with the first gear and a second clutch gear engaged with the second gear. Between the first clutch gear and the second clutch gear, a torsion spring for imparting the play to the clutch member is disposed. A combination of a protrusion portion, a lock arm cam, and a lock arm controls so that the play caused by the torsion spring is effective while a rotational angle of the first clutch gear lies in a first angular range and controls so that the play caused by the torsion spring is ineffective so as to make the first clutch gear and the second clutch gear move integrally while the rotational angle of the first clutch gear lies in a second angular range.
