<p>PURPOSE:To attain smooth descending of a cassette, to decrease the number of components and the height and then to narrow the width by providing a link connected between one of two links constituted in an (x)-shape and the base. CONSTITUTION:When a cassette is loaded and a cassette accommodating section 9 is pushed down, a pin 5b is fixed by a lock mechanism to attain tape running. In depressing an ejection lever at this position, the lock mechanism is actuated, a pin 5b is released and the 1st link 5 is turned counterclockwise by the force of a spring 10 around a shaft 5a. In this case, the 2nd link 6 fitted to the 1st link 5 is lifted up and driven clockwise around the pin 5b and the 3rd link 7 fitted to the 2nd link 6 is driven counterclockwise around the pin 8b. Then the attitude of the cassette accommodating section 9 is decided by the 2nd link 6, the 3rd link 7 and a long hole 6a. Thus, miniaturization and smoothed cassette accommodating section depression are attained.</p> |
