<p>PURPOSE:To facilitate the switching of reproduction and quick traverse by providing a movable head substrate with respect to a cartridge insertion part and a lever for fixing the head substrate on a cartridge non-insertion part. CONSTITUTION:The movable head substrate 9 with respect to the insertion part of a cartridge 1 and the lever 44 for fixing the head substrate to the cartridge non-insertion part are provided. Thus the switching of the reproduction and the quick traverse can be possible in the cartridge insertion part. Without the inserted cartridge, the switching mechanism of the reproduction and the quick traverse can be protected from the impact due to falling down and dropping by fixing the head substrate. When a plunger 36 is conducted for a short time in the reproduced state, for instance, a movable iron core 36a is attracted in the direction of an arrow 38, and the one end 22b of a plunger 22 moves counterclockwise with a shaft 21 as a center. Since a contact part is located at the position where a cam starts descending in terms of an inner cam part 20c, a cam gear 20 is turned in the direction of an arrow 40, and a stopper 20d abuts on the other end 22a of the plunger lever 22 slightly before the cam descends completely, whereby the rotation of the cam ear 20 is inhibited, to be brought into the quick traverse state.</p> |
