ABSTRACT:
A tape cassette of the type in which a tape-shaped medium having a light transmissivity at a predetermined portion is wound between an upper cassette half and a lower cassette half so as to surround a light emitting element insertion portion, a light receiving window is formed through a side wall of the upper cassette half or the lower cassette half so as to oppose to the light emitting element insertion portion across the tape, whereby when the tape cassette is loaded into a recording and reproducing apparatus, a light emitting element is inserted into the light emitting element insertion portion and a light receiving element is located outside of the light receiving window, thereby detecting the predetermined portion of the tape-shaped medium and wherein light-shielding ribs formed on the upper cassette half or the lower cassette half so as to face to each other across a light path extend from the light receiving element insertion portion to the light receiving window, and a tunnel core piece member is provided among the side wall having the light receiving window and the light-shielding ribs so as to surround the light path, whereby even when the tape cassette is formed as a color tape cassette, a start sensor or an end sensor can be prevented from malfunctioning.
