<p>PROBLEM TO BE SOLVED: To prevent erroneous mounting in mounting a magnetic tape cassette onto a magnetic tape recording and reproducing device, with a simple structure. SOLUTION: A slider 2 sets a cassette 1 thereon, and a pressure contact spring 4 for pressure-contacting the cassette 1 is mounted on the slider 2. A guide plate 3 holds pins 2a, 2b, 2c of the slider corresponding to three guide grooves 3a, 3b, 3c of the guide plate, and guides these pins horizontally and vertically. A guide pin 6 for guiding thereto a positioning hole 1b of the cassette is mounted and fixed on a chassis 5. The guide pin 6 has its conical vertex made eccentric from the center of the base circle to the side where the cassette 1 is inserted.</p> |
