20090007163 | Optical Disc Device - An optical disc device capable of sensing exactly whether or not a disc is present is provided. In an optical disc device includes a main body having a disc slot, and a carrying roller for carrying a disc between the disc slot and a disc loading position of the main body, a swinging lever whose base end is supported turnably in an inside of the main body by a supporting shaft and to which a disc arriving switch is fixed, and a sensing lever whose base end is supported turnably by the supporting shaft and whose top end contacts the outer periphery of the disc, which is loaded in the disc loading position, to operate the disc arriving switch are provided. | 01-01-2009 |
20090007166 | Optical Disc Device - To provide an optical disc device in which the number of parts is small, and quietness can be secured with a simple mechanism. The optical disc device includes a main body having a disc insertion/removal port, and a conveying roller for conveying a disc between the disc insertion/removal port and a disc receiving position in the main body, and also includes a swinging lever which is pivotally supported at its proximal end on a supporting shaft within the main body, and has a disc arrival switch fixed thereto, and a detection lever which is pivotally supported at its proximal end on the supporting shaft, and contacts an outer periphery of the disc (which is to be received in the disc receiving position) at its distal end to operate the disc arrival switch, and when the disc is to be inserted into the disc receiving position, the detection lever is projected into the disc receiving position. | 01-01-2009 |
20090010128 | Disc Identification Apparatus, Disc Insertion-Ejection Device, and Disc Device - A disc identification device, a disc insertion-ejection device and a disc device which can positively prevent two discs from being inserted into the apparatus. There is provided a disc thickness detection unit for electrically detecting a thickness of the discs inserted into an apparatus of the disc device, and there is provided a construction for judging whether the number of the discs inserted into the apparatus is one or plural, and it is electrically identified whether the number of the discs inserted into the apparatus is one or plural, and by controlling mechanisms on the basis of this identification result, the stable disc insertion and ejection can be achieved, and also damage to the mechanisms and the discs can be reduced. | 01-08-2009 |
20090025019 | OPTICAL DISK DEVICE - An optical disc device and a disc changer drive capable of achieving a reduction in cost and number of articles and a reduction in size of the disc drive with a simple configuration rather than the prior art and also carrying out a stable playing/writing operation are provided. An optical disc device includes a playing chassis which is supported turnably on a main body of the disc drive and on which a turntable is installed, a substantially Y-shaped cam groove formed on the playing chassis, a driving lever on which a substantially T-shaped cam groove is formed and which transmits a power to a holding portion of the disc, and a turning lever supported turnably on the main body and engaged with the playing chassis and the cam groove of the driving lever via a driving shaft, wherein a turning of the turning lever is followed by a turning of the playing chassis and a movement of the driving lever that follows the turning of the playing chassis to hold a disc as a series of operations. | 01-22-2009 |
20090055847 | DISC DEVICE - A disc device is capable of suppressing movement of discs remaining on standby. Discs are moved upward and downward, thereby providing an operation space S at a lower side of the desired disc, and a pivotal arm is located in a predetermined position, and thereafter the desired disc is set on the pivotal arm, and recording/reproduction is effected. At this time, the standby discs disposed at the lower side of the desired disc are disposed below the operation space (S), and are fixed by pressing pressing members of disc fixing portions against outer peripheral surfaces thereof. | 02-26-2009 |
20090055848 | DISC IDENTIFICATION DEVICE, DISC INSERTION-EJECTION DEVICE, AND DISC DEVICE - 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. | 02-26-2009 |
20090204982 | OPTICAL DISC DEVICE - To provide an optical disc device in which an identification and a disc ejection control processing for an optical disc with a high transmitting property and an 8-cm optical disc attached to an adapter can be effected easily and positively. There are provided a body capable of receiving an optical disc therein, an insertion/ejection port capable of insertion and ejection of the optical disc relative to the interior of the body, and rollers which are provided within the body, and rotate, while holding the optical disc therebetween, so as to convey the optical disc into the interior of the body. A mechanical detector, having a contact element for contact with at least one of obverse and reverse surfaces of the optical disc to detect the optical disc, is provided within the body so that an identification and a disc ejection control processing for optical discs can be effected easily and positively. | 08-13-2009 |
