PURPOSE:To enable very light rotation that does not give influences on movement of a pickup by separating contact part of a boss for resetting and a starting link which is a transmission route of vibration and shock. CONSTITUTION:After a small gear 9 arrives at a position 9b and a friction link 7 and a starting link 6 are set at positions 7a, 6a respectively, a rod 22 having an end face 22x that joins and presses an end part 7y provided in the friction link 7 is provided before a shaft 12 arrives at a rotation angle D. The friction link 7 is turned by measure E to a position 7c, and the starting link 6 mounted on it is turned simultaneously and moved to a position 6c, and a clearance of measure B is made between a boss 4. Consequently, the moment of shock from the boss 4 to the end face 6y of the starting link 6 is eliminated, and the stable position of the friction link 7 and starting link 6 maintained. |
