<p>PURPOSE:To prevent a positioning pin for compact cassette (C cassette) smaller than a standard type and a receiving pin from becoming obstacles even when a full cassette (F cassette) of the standard type is set by elevating the tip parts of the positioning pin and receiving pin for cassette. CONSTITUTION:When a C cassette 8 is set, a slide board 3 is moved in a direction, where pin members 46 and 56 are fitted to a notch 32, and abutting pieces 49 and 57 are received by a notched edge. Then, the fall of the pin members 46 and 56 is interrupted and the said pin members 46 and 56 are engaged to the C cassette 8. When an F cassette 7 is set, the slide board 3 is moved in a direction reverse to the above mentioned direction and a positioning pin 4 and a receiving pin 5 for cassette are detached from the notch 32 so that the pins 4 and 5 can fall down against springs 45 and 55. Thus, when the F cassette 7 is set, the lower surface of the F cassette 7 makes the positioning pin 4 and receiving pin 5 for C cassette 8 pressed and falling and accordingly, the pins 4 and 5 do not become obstacles.</p> |
