PURPOSE:To facilitate mounting a record disc by providing record disc guide parts having a guide surface for record discs on the lower outside circumferential surface of a turntable. CONSTITUTION:Record disc guide parts 9 and 10 are provided symmetrically on the circumferences of respective alpha deg. (more preferably 10 deg.<alpha deg.<90 deg.) in clockwise and counterclockwise directions with respect to the sectional face line Y-Y from the front face of a record player so as to offer convenience in supporting the lower part of a record disc 5. Hereupon, the forming place of the guide part 9 is provided in such a position of rG where the relation r4<rG<r4+d/2 holes where the distance from the center of center shaft 2 up to the inside wall G of the guide part 9 is defined as rG, the radius of the record disc 5 as r4 and the diameter of a hole as (d). With such constitution, the record disc 5 is mounted to the record player accurately and easily. |
