DISC-LOADING APPARATUS
Document Type and Number:
Japanese Patent JP3294483
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve problems possibly causing abnormal reading/writing of data or abnormal rotation of a disc when a hub of the disc cannot be in tight contact with a chuck magnet.
SOLUTION: A chuck magnet 104 for attracting hub of a loaded disc is fixed at a turntable part 103 of a rotor yoke 101. A swing arm 105 is arranged between the chuck magnet 104 and the rotor yoke 101 in a manner to be able to swing. The swing arm 105 is formed out of a synthetic resin having a driving pin 106a at one end has a metallic plate 107 fixed to confront the rear face of the chuck magnet 104. When the driving pin 106a agrees with a positioning hole of the hub of the loaded disc, the metallic plate 107 is attracted by a magnetic attraction force of the chuck magnet 104, so that the swing arm 105 is secured to the chuck magnet 104. As a result, the exposed driving pin 106a penetrating the chuck magnet 104 is engaged with the positioning hole of the hub.
