    摘要： An optical pickup device for recording and/or reproducing the information on or from an optical disc. The optical pickup device includes a cover plate for covering said through-hole of said lid when said optical pickup unit is moved by said optical pickup feed unit until the objective lens is located outwardly of the optical disc loaded on said disc rotating driving unit; an abutting portion provided on one of said lid and the cover plate, said abutting portion causing movement of said cover plate in a direction away from the objective lens when said optical pickup unit is moved by said optical pickup feed unit so that said objective lens is positioned outwardly of said optical disc; and an engagement portion provided on the other of said lid and the cover plate, said engagement portion engaging with said abutting portion when, after said cover plate is moved by said abutting portion in a direction away from the objective lens, the optical pickup unit is further moved to outwardly of the optical disc by said optical pickup unit. The optical pickup unit is held in stability on an outer rim side of the optical disc, whilst it is possible to prevent dust and dirt from being intruded inti its inside.

    摘要： An optical pickup device includes a feed screw to move an optical pickup having an objective lens radially on an optical disc, a sliding member provided for slidable movement in relation to the optical pickup, and connected to the optical pickup by a coil spring that forces a shutter in a direction of unmasking the objective lens, and a connection member that connects the feed screw and sliding member to each other. As the feed screw is rotated, the sliding member moves the optical pickup radially on the optical disc, and when the optical pickup has arrived at a position at the lead-in side of the optical disc, the sliding member is further slid against the force of the coil spring to move the shutter and mask the objective lens.

    摘要： A universal joint includes a yoke having a fitting portion for fitting a shaft. The fitting portion has first and second tabs opposed to each other to form a U shape. A fixing mechanism including a bolt passing through respective insertion holes in the first and second tabs and a nut screwed onto the bolt on a fastening axis fastens and fixes the shaft between the first and second tabs. A nut holding member fixed to the second tab has an engaging piece. The engaging piece causes the nut, which has not been screwed onto the bolt, to be held on the fastening axis. A cover held by the nut holding member covers at least the engaging piece around the nut.

    摘要： A defect information storing device includes two tables for storing information on defective points of a semiconductor device. The first table stores column addresses and number of defective points existing at this column address for (r×c+c) lines. The second table stores row addresses, number of defective points existing at this row address, and column identifiers indicating the storage place of the column address of the defective point in the first table for (r×c+r) lines.
