摘要： An optical disc drive in which vibration characteristics are enhanced by preventing vibration of a rotary arm. Recording/reproduction is carried out by selecting a desired optical disc (12) from a plurality of optical discs (12) contained in a stacked form, positioning a turntable (31) by rotating a rotary arm (30) into a work space provided for the desired optical disc (12), and moving an optical head (34). Since the forward end part of the rotary arm (30) of cantilever structure is supported by a supporting member (40) extending along the center line CL of the optical disc (12), the cantilever structure is built and vibration of the rotaryarm (30) can be prevented. Since the supporting member (40) extends along the center line CL of the optical disc (12), the supporting member (40) extends through the central holding hole (12a) of the optical disc (12) and a cut (22) provided in the center of a tray (20) with no interference and supports the rotary arm (30).

摘要： An optical disc device which has a small number of components and ensures quietness by a simple mechanism. The optical disc device (10) is provided with a main body having a disc inserting/ejecting port (11), and a transfer roller for transferring a disc between the disc inserting/ejecting port (11) and a main body. The optical disc device is also provided with a rocking lever, which has its base end rotatably supported inside the main body by a supporting shaft, with a disc reaching switch fixed on the rocking lever; and a detecting lever, which has its base end rotatably supported on the supporting shaft and permits the disc reaching switch to operate when a leading end is brought into contact with an outer circumference of the disc stored at a disc storing position. When the disc is inserted into the disc storing position, the detecting lever is protruded to the disc storing position.

摘要： An optical disc drive capable of attaining a uniform and sufficient optical disc holding force. When recorded information is reproduced by holding an optical disc (12), recording face (12a) of the optical disc (12) is mounted on the mounting part (32) of a clamp mechanism (30), a projecting part (33) is passed through the hollow section (12c) of the optical disc (12) to the label side (12b), and the optical disc (12) is held by projecting a chuck pawl (35) from the projecting part (33). The chuck pawl (35) grasps the optical disc (12) by turning about a supporting shaft (34) extending along the tangential direction of the projecting part (33), and the proximal end part (35a) of the chuck pawl (35) is pressed by a resilient pressing part (36a) provided on a press member (36) and turned. When a specific chuck pawl (35) is hooked, the part (36a) pressing the hooked chuck pawl (35) deforms resiliently to allow movement of the press member (36) and an other pressing part (36a) presses the proximal end part (35a) of another chuck pawl (35). Consequently, an other chuck pawl (35) can grasp the optical disc (12) surely.

摘要： A disc device which can suppress moving of discs being in a standby state. The disc device provides a working space (S) below a desired disc (12) by vertically moving the disc (12), and after a turning arm (30) is positioned at a prescribed position, the desired disc (12) is set on the turning arm (30) and record reproduction is performed. At this time, standby discs (12A) below the desired disc (12) are at a lower part of the working space (S) and are fixed by pressing a pressing member (71) of a disc fixing section (70) on an outer circumference plane.

摘要： An optical disk device for discriminating the kind and the insertion status of an optical disk with a simple mechanism so that it can unload the optical disk in case something is wrong. When the loading of the optical disk (12) recorded with information is started, a pair of rollers (14, 14) are rotated to clamp the optical disk (12) inserted into the slot (11) of the body (13) of the optical disk device (10) and load the disk into the inside of the body (13). At this time, circumferential edge detection means (20) disposed in the body (13) continuously detects the circumferential edge (12a) of the optical disk (12) inserted, so that it detects the external diameter, shape and insertion status of the optical disk (12) inserted. In case something wrong is judged, the optical disk (12) is unloaded.
