CONSTITUTION:The cassette holder 2 holding the cassette 1 is held freely slidably along a gide groove provided for a guide plate 4 of the cover 3. The upper end of the cover 3 is provided with a stopper 5, a lower end of a pair of left and right parallel moving plates 6 is linked freely turnably to a bracket 7 at the lower end of the cover via a link pin 8 and the plates are arranged almost vertically. The cover 3 is energized turnably toward the direction (counterclockwise in the figure) to be opened to the plates 6 with a torsion spring 9 inserted to the outer circumference of the link pin 8 and both ends of a pair of left and right link levers 10 are linked freely turnably to the lower end of the cassette holder 2 and the upper end of the plates 6 via links pins 11, 12 respectively. |
