    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.
