Magnetic tape device has clamp roller with tubular roller part for engagement with drive roller via tape, tubular bearing part formed of resin, groove area formed in longitudinal central area

摘要

The device has a tape drive roller and a clamp roller (12) for driving a magnetic tape. The clamp roller has a tubular roller part (12b) whose outer periphery can be brought into engagement with the drive roller via the tape, a tubular bearing part (24) formed of a resin material and a groove area (25) formed in a longitudinal central area of the outer periphery so that flange areas (26) are formed that contact the inner periphery of the roller part on both sides of the groove area. A roller shaft (18) is mounted inside the bearing part.
