Abstract

PURPOSE:To satisfactorily apply a tonearm driving clutch of an autoplayer in a desired position of the tonearm by turning the trigger lever, which is operative to actuate clutch means, with the use of a hollow coil and a magnet. CONSTITUTION:At any time when a tonearm 33 fails to reach the terminal end of rotation, a lever 46 is turned to the solenoid 50 of a hollow coil and a trigger lever 46 by the repulsion of a stationary magnet 49. Then, a lutch gear 7 is cooperatively turned, and a gear 2 made integral with a turntable shaft is brought into engagement with a gear 7 to apply the clutch so that a tooth-removed gear effects a half turn. As a result, the tone arm 33, which is adapated to be turned through a drive lever 13, a main lever 17 and a lead-in lever 35, is returned to the lead-in position by the lever 35 which has its return restricted when a select lever 37 abuts against a cam 43. By the clutch actuating mechanism using the hollow coil having no plunger and no change in the operation starting point, the clutch to be applied upon detection of the terminal end of the arm 33 is satisfactorily operated at any position of the arm 33 to effect the return of the tonearm.
