<p>PURPOSE:To reduce a load at the initial shift and to ensure a smooth shift of a mobile member, by shifting a fixed member of a mechanism part which damps shift of the mobile member locked at the 1st position to the 2nd position, in the reverse direction of a mobile bar. CONSTITUTION:A mechanism such as a kangaroo pocket 2 of a cassette deck that shifts a mobile member from the 1st position to the 2nd position moves from the 1st position (loading state) to the 2nd position (loading/unloading of cassette) by the functions of a locking member 8, springs 4 and 6, a piston 9 forming a damper mechanism, a cavity part 8c, etc. When the member 8 is turned at the 1st position, the part 8c moves to the piston 9. Then the pocket 2 starts moving to the 2nd position when a taper 8a' of a hollow part 8a reaches a pin 2a. Thus the piston 9 starts moving to the side opposite to the part 8c. As a result, the initial load between the part 8c and the piston 9 is reduced. Thus the initial movement is started smoothly to ensure a smooth shift of the mobile member from the 1st to 2nd position.</p> |
