A disk loading apparatus may include a first retaining device that is arranged in a slot for a disk to be inserted and thereby retains the outer edge of the disk so as to permit it to pass through the slot. A transferring device transfers the disk retained by the first retaining device to a predetermined position. A second retaining device is arranged in the interior from the slot and thereby retains the outer edge of the disk retained by the first retaining device and transferred by the transferring device. A rotating device rotates the disk at the predetermined position. Also, each of the first and second retaining devices has a contact section for contacting with the outer edge, upper surface, and lower surface of the disk in a slidable manner.

Disk loading apparatus in recording and reproducing apparatus

A disk retaining mechanism that realizes a reduction of its thickness while maintaining a clamping force and a centering accuracy of the clamper, with a structure, in which: a guide ( ) is disposed in a manner to closely confront a clamper retaining member ( ); a clamper unit retaining portion of the clamper retaining member ( ) has such a shape that a part of which an entire circumference is cut out; a clamper unit for depressing a disk ( ) is provided with a disk holder ( ) having an engagement projection (M); and an annular engagement groove (F) formed in a turntable ( ) for loading the disk ( ) is arranged below an upper end of a main shaft ( ) that transfers rotation of a motor unit ( ).

Disk holding mechanism and disk holding mechanism clamper

A disk loading apparatus is provided which stops disks, even if the disks have different diameters, when disk center holes have been ejected to the substantially same positions out of an apparatus body during the ejection. The disks can be pulled out without soiling a recording surface of the disk. One disk-pass detecting switch detects a pass of the last end of each disk and discriminates sizes of the disks. In addition, a rotation time of a roller after the detection of the pass is controlled depending on disk diameters.
