PURPOSE:To miniaturize a device by permitting a tone arm to rotate onto a turntable only when the mounting of the turntable on a motor sliding plate is detected. CONSTITUTION:Motor sliding plate 5 is supported movably between play position (d) and record change position (c) before it. Turntable 6 is provided detachably to motor sliding plate 5 and only when the mounting of turntable 6 on motor sliding plate 5 is detected on the movement of motor sliding plate 5 from record disk change position (c) to play position (d), tone arm 7 rotates onto turntable 6 and in other cases, tone arm 7 rotates toward motor sliding plate 5 even at record disk change position (c). |
