摘要： A tape cartridge that has a clamp force to a block body and that secures a leader tape to a leader block is provided. Nail portions (63a, 64a) formed on the outer surface sides of a pair of leg portions (63, 64) of a damper (36′) are secured to securing grooves (53, 54) formed on side walls of a assembling concave portion (50) of a block body (40) to secure the block body (40) and the damper (36′). At this point, with concave grooves (73, 74) and a reinforcement rib (75) formed on an inner surface side of a base portion (60) that composes the damper (36′) in the elongation direction of the leg portions 63 and 64. Thus, when the damper (36′) is pushed, it can be prevented from being damaged and a desired clamp force can be obtained.

摘要： A tape cassette includes a shell, first and second bosses arranged on the inner surface of the shell, and a prism mounted on the inner surface of the shell and formed with first and second holes and having an optical axis which corresponds to an optical axis of light emitted from a tape-position sensor of a drive. The first and second bosses are arranged through the first and second holes. When the first and second bosses contact the inner peripheral surfaces of the first and second holes, a first clearance between the first boss and the first hole and a second clearance between the second boss and the second hole is produced in the opposite direction of the first and second bosses with respect to the optical axis of the prism.
