いようにしたことを特徴とするテープカセツト。 When installed in a recording and/or reproducing device, the light beam from the light emitting element of the device passes through the transparent part provided at the end of the magnetic tape and the first and second holes provided in the side wall of the tape cassette, respectively. The tape cassette is configured to reach a light receiving element provided in the device that operates the tape end detection mechanism through the tape cassette, and has a tape remaining amount confirmation window for checking the remaining amount of magnetic tape, The confirmation window is formed of a material whose light transmittance varies depending on the angle of incidence, so that scattered light rays other than the light rays from the light emitting element do not reach the light receiving element through the first and second holes. A tape cassette characterized by:
