Abstract
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.
