Abstract

PURPOSE:To position the record disks of different diameters inserted at a preset position by using as a guide of the record disks the right and left rollers which are carred on the rocking arms made rotatable symmerically to the right and left through upper and lower rollers and racks. CONSTITUTION:There are mounted in a record disk inlet 10 both upper and lower rollers 58a and 58b and 54 and left and right drum-shaped rollers 69a and 69n which are attached to the ends of rocking arms 70a and 70b. Pinions 68a and 68b at the rocking center of the arms 70a and 70b are brought into meshing engagement with the racks 71a and 71b, which are made coactive and are adapted to restore their initial position by a bias spring 72 so that the arms 70a and 70b are rocked symmetrically to the right and left in the opposite directions. As a result, the record disks which are guide upon insertion by the rollers 58a, 58b, 54, 69a and 69b take a preset position after insertion even if they are of kinds having different diameters.
