    • An optical system comprises an objective lens for moving along a recording face of an optical disk in the radial direction of the optical disk so that an optical axis thereof is almost perpendicular to the recording face, a reflecting mirror for moving together with the objective lens and whose reflecting axis extends in the radial direction, a detection optical unit, a movable mirror located to incline with respect to the optical axis extending almost parallel to the recording face from the detection optical unit and the reflecting axis of the reflecting mirror, and a mirror drive portion for rotating the movable mirror on an axis almost parallel to the recording face and shaking a light beam radiated from the objective lens onto the recording face in the radial direction. The mirror drive portion rotates the movable mirror on an axis almost parallel to an optical axis extending from the detection optical unit or on an axis almost parallel to a reflecting face of the movable mirror. Reflecting axes of the reflecting face are disposed on the same plane parallel to the recording face.
    • 一种光学系统包括:物镜,沿着光盘的径向方向沿着光盘的记录面移动,使得其光轴几乎垂直于记录面,用于与物镜一起移动的反射镜和 其反射轴沿径向延伸,检测光学单元,相对于从检测光学单元和反射镜的反射轴几乎平行于记录面延伸的光轴倾斜的可移动镜,以及镜 驱动部分,用于在几乎平行于记录面的轴上旋转可移动反射镜,并将从物镜辐射的光束沿径向方向摇动到记录面上。 反射镜驱动部在与检测光学单元延伸的光轴大致平行的轴上或大致平行于可动镜的反射面的轴上旋转可动镜。 反射面的反射轴设置在与记录面平行的同一平面上。

    • To provide a winker apparatus in which assembly thereof is improved by eliminating the necessity to check biting of the winker cord. A front winker includes a winker holder mountable to a front fork. A winker body is mountable to one side of the winker holder via a winker supporting base. A winker cord is lead from the winker holder via the winker supporting base. The winker holder is formed with a storage groove for accommodating the winker cord. A cover is provided for covering the storage groove so as to retain the winker cord in a state in which the winker cord is stored in the storage groove.
    • 为了提供一种通过消除检查方向指示灯的咬合的必要性来提高组装方式的方法指示装置。 前装饰板包括安装在前叉上的方向指示灯座。 方向指示灯主体通过方向指示灯支撑座安装在方向指针座的一侧。 方向指示灯通过方向指示灯支撑底座从方向指示灯座引导。 方向指针支架形成有用于容纳方向指示灯的存储槽。 设置有用于覆盖存储槽的盖,以便将方向指示灯条保持在储存槽中的方向指示灯的状态下。
