<p>PURPOSE:To avoid deformation of a lock member or a kick member by moving the lock member to guide a guide part even at the time when the kick member constituting a lock mechanism is operated and a cassette stage performs the cassette loading operation in this state. CONSTITUTION:A slide chassis 8 is attached to a chassis 1 so that the chassis 8 can be moved in the direction of an arrow A, and a cassette stage 7 can be turned with a turning fulcrum 7a as the center. An engaging pin 2 is provided, and a cassette holder 7b to hold a cassette 6 is attached to the stage 7, and the stage 7 is engaged with the pin 2 of the chassis 1 against the force of a stage energizing spring omitted in the figure and is locked, and this lock member 3 can be turned with a fulcrum 3a as the center. The member 3 is energized by an energizing spring 4 to perform the lock operation, and a turnable kick member 5 is attached to the chassis 1. Thus, the lock member 3 is turned against the spring 4 to guide the member 5 to a guide part 5a.</p> |
