Optical pickup apparatus and optical parts accommodation module for optical pickup
摘要：
An optical pickup apparatus (100) is provided with: a carriage body (80); an optical parts accommodation module (70) mounted on said carriage body and accommodating at least (i) a light beam emitting portion (41, 42, 55) for emitting a light beam, (ii) a light beam receiving portion (57, 65), (iii) a beam splitter (44) and (iv) a grating (43) for generating a sub beam for a tracking adjustment out of the light beam emitted from said light beam emitting portion; and a grating adjustment mechanism (62, 63) for rotating said optical parts accommodation module. The optical parts accommodation module is mounted on said carriage body in such a condition that said optical parts accommodation module is allowed to rotate with an axis line of the light beam, which is irradiated toward a disc, as a rotational center. The grating adjustment mechanism has a cam plane (63) abut to an abut plane (52) formed at a portion apart from the axis line and including a slide cam member (62) mounted in such a condition that said slide cam member is regulated to be movable on a straight line with respect to said carriage body.
摘要（中）：

光拾取装置（100）具有：滑架主体（80）; 安装在所述滑架主体上并容纳至少（i）用于发射光束的光束发射部分（41,42,55）的光学部件容纳模块（70），（ii）光束接收部分（57,65 ），（iii）分束器（44）和（iv）光栅（43），用于产生用于从所述光束发射部分发射的光束中的跟踪调整的子光束; 以及用于旋转所述光学部件调节模块的光栅调节机构（62,63）。 光学部件容纳模块以允许所述光学部件容纳模块以朝向盘照射的光束的轴线为旋转中心的方式旋转的状态安装在所述滑架主体上。 光栅调整机构具有与形成在与轴线分开的部分处的抵接平面（52）的凸轮平面（63），并且包括滑动凸轮部件（62），所述滑动凸轮部件（62）以将所述滑动凸轮部件调节到 可相对于所述滑架主体在直线上移动。
