<P>PROBLEM TO BE SOLVED: To suppress adhesion of dust and the like to a reflection mirror without incurring increase of the number of components of an optical pickup device and upsizing of the optical pickup device. <P>SOLUTION: In the optical pickup device 1 wherein light from optical integrated elements 11 and 21 via collimator lenses 12 and 22 variably moving along optical paths between the optical integrated elements 11 and 21 and reflection mirrors 13 and 23 is emitted to reflection surfaces of the reflection mirrors 13 and 23 and light reflected by the reflection surfaces is condensed by objective lenses 14 and 24, the collimator lenses 12 and 22 are supported by a lens holder 30, and a covering part 31 is provided, which covers spaces on the reflection surface sides of the reflection mirrors 13 and 23 when at least the collimator lenses 12 and 22 are in standby positions and is provided integrally with the lens holder 30. <P>COPYRIGHT: (C)2011,JPO&INPIT |
