    • It is an object of the present invention to provide an electronic equipment of a high design property having an optical disc drive mounted thereon and an inexpensive and high-quality opening and closing mechanism for a tray door. The electronic equipment includes a front panel on a front surface of the equipment, and a link 25 rotatably engaged with a tray door 22. The tray door is provided with cams 22b engaged with cam pins 20b provided on the front panel to control the locus of the movement of the tray door. The discharging movement of the tray causes the link to be pushed and rotated by the tray, whereby the tray door is slid to below the tray with its upper design surface left turned upwards in the form of the movement controlled by the rotation of the link and the locus of the cams, and in this manner, the tray door is opened. The link is pressurized by a torsion spring in a rotational direction to push a tray for an optical disc, and when the tray is retracted, the tray door is closed by the pressurization applied to the link by the torsion spring.
    • 本发明的目的是提供一种具有安装在其上的光盘驱动器的高设计性质的电子设备和用于托盘门的便宜且高质量的开闭机构。 电子设备包括在设备的前表面上的前面板和与托盘门22可旋转地接合的连杆25。 托盘门设置有与设置在前面板上的凸轮销20b接合的凸轮22b,以控制托盘门的移动轨迹。 托盘的排出运动导致连杆被托盘推动和旋转,由此托盘门滑动到托盘的下方,其上部设计表面以由连杆的旋转所控制的运动的形式向上转动, 凸轮的轨迹以这种方式打开托盘门。 连杆由旋转方向的扭转弹簧加压以推动用于光盘的托盘,并且当托盘缩回时,托盘门通过由扭转弹簧施加到连杆的加压而关闭。

    • The present invention comprises an arrangement with removable optical element having a predetermined focal distance in the light path between a light source and an objective lens, so as to insert said optical element into the light path between the light source and the objective lens for playing back or recording onto one type of thickness of disk plates, as well as to remove it therefrom for playing back or recording onto another type of thickness of disk plates. Alternatively, by retaining variably the distance between the light source and the collimator lens, the distance between the light source and the collimator lens along with the light path is variably changed according to the thickness of the disk plate being inserted. Then by determining the type of the disk inserted and accordingly selectably inserting/removing the optical element, only one objective lens may be used to conform to the disk plates having different thicknesses.
    • 本发明包括具有在光源和物镜之间的光路中具有预定焦距的可拆卸光学元件的装置,以便将所述光学元件插入光源和物镜之间的光路中以便回放 或记录在一种类型的盘片的厚度上,以及将其从中移除,以便播放或记录到另一种厚度的盘片上。 或者,通过可变地保持光源和准直透镜之间的距离,光源与准直透镜之间的距离以及光路可根据插入的盘片的厚度而变化。 然后,通过确定插入的盘的类型并相应地可选择地插入/移除光学元件,可以仅使用一个物镜来符合具有不同厚度的盘片。
