<p>PROBLEM TO BE SOLVED: To reduce the load of a cam mechanism and the shock noise by constituting the cam part so as to elastically deform. SOLUTION: This mechanism is provided with a cam shaft 41 fixed to a head plate 40 and a cam 10 rotationally driven in the specified direction for changing over the mode from a reproduction mode to a stop mode, and this cam 10 is provided with the cam part 10b for engaging the cam shaft 41 with the reproducing position at the reproduction mode also for guiding it to the end part 10s by changing over the mode and the cam part 10t for guiding the cam shaft 41 which is moved from the end part 10b, to the direction of the stop position by changing over the mode while confronting away with the end part 10s of the cam part 10b, and when the cam shaft 41 is moved to the cam part 10t from the end part 10s by changing over the mode, the dropping distance of the cam shaft 41 to the cam part 10t is reduced by the elastic deformation of at least the end part 10s to the direction of the cam part 10t, thereby the shock noise of the cam shaft 41 due to this dropping is reduced.</p> |
