PURPOSE:To reduce the fitting space of a fitting member for a cover by constituting an opening and closing device by forming two slide paths in the fitting member and by engaging a T-shaped link member with them. CONSTITUTION:When an ejecting operation is performed at the closure position of a cassette holder, a mechanism concealment plate 18 pivoted rotatably on a fitting plate 15 turns as shown by an arrow (a) and a pin 26 implanted in the mechanism concealment plate 18 moves along a bent groove 25 made in a cassette holder. Simultaneously, a T-shaped link member 20 also rotates around a shaft 23 and pins 21 and 22 move along long-sized holes 16 and 17 made in the fitting plate 15 as shown by arrows (b) and (c) respectively. Consequently, the cassette holder moves in parallel as shown by an arrow (d) and then rotates as shown by an arrow (e) to be opened. |
