<p>PURPOSE:To smooth operation and to prevent an impulse noise from being generated by applying a load to the move of an operating member by a spring member when the operation of a cam lever, whose one side is locked by the operating member, is switched to the lock after operation is completed. CONSTITUTION:A cam lever 6 has a side 6a, which contacts an operating member 5 to execute linear motion and holds an angle, and a side 6b to be operated by the operating member 5, and the cam lever is linked to an operating mechanism such as the loading mechanism, etc., of a tape player. When the operating member 5 is moved and the contact is switched from one side to the other side, a spring member 16 contacts the operating member 5 and goes to be the load for the move of the operating member 5. Accordingly, for a rapid change from a condition that there is the large load for the operating member 5 to operate the cam lever 6 to a condition that the load goes to be small resistance for the operating member 5 to slide on one side of the cam lever 6, a change rate can be reduced by the load of the spring member 16 contact. Thus, the operation of the operating member 5 is smoothly executed and the impulse noise can be prevented from being generated.</p> |
