<p>PURPOSE:To prevent the injury to be inflicted on a magnetic tape by forming the shape of a guidance part which is approximately orthogonal to the loading direction of a tape cassette so that the tape cassette is fitted to a positioning shaft while the cassette is moved back to the front side in the cassette loading direction to prevent the defective loading. CONSTITUTION:When a tape cassette 3 is loaded in a normal state, a cassette holder 2 guided once the cassette 3 up to the inner side. Then the holder 2 is moved back forward slightly according to the form of a vertical lift guidance part 16v of a guiding groove 16 and at the same time moved down. As a result, a shaft hole opening toward the lower surface side of the cassette 3 is matched with a positioning shaft 12 with sufficient margin even in case the cassette 3 is deviated from a normal loading state as shown by a 1-dot chain line. This can prevent assuredly a defective loading state of the cassette 3.</p> |
