Abstract

PURPOSE:To easily obtain a highly accurate and simple device with a thin form by providing a moving device on the side of a magnetic bias unit, or a moving body and carrying out the determination of a moving force and a moving quantity and the holding of a moving posture by means of links, stoppers, and a spring. CONSTITUTION:The roller 10 of a first link 8 is rotated downward against a spring 9 with a center shaft 8b as a support shaft accompanying the movement of a cam 11. At that time, the end of a link 8 is brought into contact with a first stopper 13 restricting the moving quantity, and a magnetic bias unit 1 is moved from the solid line position to the two-dot chain line position and stopped. Thereby, the unit 1 approaches a photo-magnetic disk 7, to apply a magnetic bias to the disk 7. Also, at the time of moving the unit 1, the unit 1 is supported being loosely fitted on the support shaft 12b of a second link 12, and the posture of the unit 1 is always held horizontally as it is moved, with a shaft 12a as a rotating fulcrum to make the unit 1 approach in parallel to the photo-magnetic disk face. Then, at the time of returning the unit 1 to its original condition, the roller 10 is moved by means of the cam 11 and, opposite to the above procedure, the link 8 is restored upward by means of the spring 9 and the top face of the unit 1 is brought into contact with a stopper 14.
