PURPOSE:To make the linking between an operation section and a mechanism section provided for a case main body easy, through the constitution that a record disc size selecting mechanism and lead-in and lead-out mechanisms for a tone arm are fitted to one base together with a motor and the tone arm and they are inserted from an opening of the main body case. CONSTITUTION:A support axis 3 of a turn table 4 is fixed to a base 1 and reciprocates in following to a large gear 9 turned with a small gear 7 turned incorporatedly with the turn table 4 and a cam of the large gear 9, and a drive plate for lead-in/lead-out of a tone arm 12 is suspended at the lower surface of the base 1. Further, since a turn table drive motor 5, a record disc size selection mechanism, a motor power supply switch operating mechanism, the tone arm 12 and a tone arm stand 11 including a lift mechanism of the arm 12 are fitted to the base 1, the assembling can simply be made from upward by inserting the base 1 to a mounting hole provided at the upper surface of the main body case. |
