摘要： Apparatus for inspection and repair of recording tape cassettes, particularly videotape cassettes, includes a base having a recess for stationarily receiving the cassette housing and an adjacent channel for receiving and maintaining the tape cover in open dispostion, and a tape advance mechanism having a pair of drive hubs engageable with the tape reels and a clutch release pin simultaneously engageable with the cassette's clutch mechanism to permit manual advance of the tape in either forward or reverse directions. A pair of spindles are mounted on the base in spaced relation to permit a medial extent of the tape to be withdrawn and trained sequentially about the spindles to maintain a portion of the tape transiently exposed for visual inspection during manual advance of the tape. The apparatus is particularly suited for locating and correcting twists, wrinkles, tears, cuts, etc. in the tape of the cassette.
