Patent ID: 8355309

Claim:
An optical pickup device comprising: a first optical system including: a first light source; a first mirror member that reflects light from the first light source to change a direction of propagation of the light to a direction substantially perpendicular to information storage surface of an optical disc; a first objective lens that condenses the light reflected off the first mirror member on the information storage surface; and a first light receiving element that receives return light resulting from the reflection off the information storage surface; a second optical system including: a second light source that emits light having a wavelength different from the first light source; a second mirror member that reflects the light from the second light source to change a direction of propagation of the light to the direction substantially perpendicular to the information storage surface; a second objective lens that condenses the light reflected off the second mirror member on the information storage surface; and a second light receiving element that receives return light resulting from the reflection off the information storage surface; and an objective lens actuator that includes a lens holder holding the first objective lens and the second objective lens and that can move the first objective lens and the second objective lens at least in a focus direction and in a track direction, wherein the first optical system and the second optical system are arranged such that a direction in which the light from the first light source enters the first mirror member is substantially perpendicular to a direction in which the light from the second light source enters the second mirror member, the first mirror member and the second mirror member each is a plate-shaped member that is substantially rectangular as seen from a reflective surface, a cut surface is formed in one of the first mirror member and the second mirror member by cutting a side surface of the plate-shaped member obliquely with respect to the reflective surface, and the cut surface and one side surface of the first mirror member or the second mirror member in which a cut surface is not formed are arranged substantially parallel to and opposite each other, and the first mirror member and the second mirror member are arranged close to each other.
