    摘要： An optical disk device capable of securing a rigidity of a tray that holds an optical disk is provided. When an optical disk is put into trays stacked in a main body, a holding portion provided to the tray holds the optical disk. In this case, since the holding portion holds the optical disk from the label face side of the optical disk, a recording face located on the opposite side to the label face can be opened without provision of a notch in the tray. Accordingly, a rigidity of the tray can be secured.

    摘要： A disc device is for electrically identifying and determining the number of discs inserted into the disc device. Roller members for coming in contact with a disc inserted into the device, transporting the disc, and inserting and ejecting the disc are provided in the vicinity of a disc insertion slot of a cabinet. A lever member for engaging a lever engagement part of a roller member and capable of rotating with a stem member as a supporting point and a push switch for detecting displacement of the lever member are provided. If the disc is inserted into the device, the roller member displaces in the up direction of the disc (A direction in a figure), the lever member displaces in an H direction in the figure, and the displacement of the lever member is detected by the push switch, whereby the thickness of the disc inserted into the device is detected.

    摘要： Space for an optical pickup at a position set aside from a disk accommodating section is to be compressed, thereby to reduce an overall size of an optical pickup device. For such a purpose, the optical pickup unit is held by a screw shaft and a guide shaft parallel to each other, and the screw shaft, the guide shaft, a first connecting plate and a second connecting plate constitute a quadrilateral parallel link. The screw shaft and a chassis holding a turntable are oscillated by a driving motor pivoting on the first connecting plate. In an escape position in which the optical pickup device is away from the disk accommodating section, a gap between the screw shaft and the guide shaft is narrowed.
