Abstract

PURPOSE:To shorten a lead-in time, by detecting not only a state that a musical performance can be executed, but also size of a record and a position of a tone arm, and moving the tone arm onto a musical performance start position of the record. CONSTITUTION:When a cover 4 of a player body 2 is closed, the microswitch is closed, and a musical performance is ready. Subsequently, size of a record is detected by a pair of light emitting and photodetecting elenents provided on a position opposed to the outside of a turntable 1 and the cover 4. AT the same time, a position of a tone arm 6 is detected by optical sensors 43, 44 provided on the lower part of an arm carrier 42 moving along guide rails 41a, 41b, and a slit plate 46 having a slit 45 extending in the guide rail direction in the space between the sensors. By the detected size and position signals, the tone arm 6 is moved to a musical performance start position of a record. In this way, a lead-in time becomes zero in case of a record of the same size, and even in case the size is different, the lead- in time is shortened.
