PURPOSE:To turn and stop the turning body of a pickup arm lifter surely without the need for any stopper and without producing mechanical sounds by stopping the turning body by the balancing in the moments generated therein. CONSTITUTION:When the user makes cuing-up operation, a DC solenoid 92 disposed on an arm base 30 is conducted, and attracts a flapper 91 which is mounted at one end to a fitting 83. As the flapper 91 is attracted, a connecting lever 90 moves, and a cam body 80 connected to the lever 90 is turned against the energizing of a spring 82, and the lever 90 aligns to the cam body 80. The body 80, the lever 90 and the flapper 91 are stopped by balancing of the counterclockwise moment generated in the body 80 by the attraction force F of the solenoid 9, and the clockwise moment generated in the body 80 by the tensile force of the spring 82. |
