| 摘要 |
The present invention provides a damper comprising a circular dish-shaped bottom surface portion for pressing an optical disk, an annular magnet member provided at a central portion of an upper surface of the bottom surface portion, a plurality of base pieces spaced apart from each other and disposed around the magnet member, a plurality of elastic arm pieces bent and extending in the same direction from the respective base pieces, and substantially horizontal stopper fins provided at tip portions of the respective arm pieces and protruding in a radially outward direction of the bottom surface portion. A stroke (vertical movement) of the damper in association with a loading/unloading action of a tray, which allows the optical disk to be placed, is secured by a helical movement action along the arm pieces, thereby reducing a thickness of the damper for sandwiching and holding the optical disk. It is also possible to reduce thicknesses of a recording/reproducing apparatus comprising the damper and an electronic apparatus comprising the recording/reproducing apparatus.
