PURPOSE:To automatically execute the lead-in and out by means of a simple constitution, by controlling the release of the locating plate detaining by the driving plate which is moved by driving force of the turntable. CONSTITUTION:A control plate 47 is rotated counterclockwise through a cam detaining plate 52 by a connecting lever 57 which is interlocked with the start lever, also a large gear 21 is engaged with a small gear 17 of the turntable motor by a cut lever 50, and a driving plate 27 is moved to the right through a cam 21c. A plate 47 is returned to its original position by a projection part 27c, a locating plate 35 which is released from stop is rotated by a spring 38, and a pawl 30 which has been released from its controlled rotation by a connecting lever 34 is rotated by the elastic force of a spring 33. As a result, a pin 4a of a working plate 4 is stopped by a stopping projection piece 30b, and when the plate 27 is returned to its operation, an arm shaft 3 of a tone arm 2 is rotated together with a plate 4 until a pin 4b is stopped at a concave part 35a, etc. of a plate 35, and the automatic lead-in is executed. |
