The other of the front wall and the connecting portion has a guide groove which extends in the ascent and descent direction and is engaged with the guide boss, and a guide rib having a guide surface for deforming the press projection to generate an elastic force and provided adjacent to the guide groove. | 04-02-2009 |
| 20100153980 | Optical-Means Driving Device - In a conventional optical-means driving device mounting a plurality of objective lenses, a lens holder is provided with introduction holes to serve thereinto inner yokes, so that it has been difficult to enhance stiffness and to increase secondary resonance. | 06-17-2010 |
| 20100162282 | Optical-system driving device - An optical-system driving device is achieved that can switch over between objective lenses and is space-saving, lightweight, and simply-configured. | 06-24-2010 |
| 20100205624 | OPTICAL DISC DEVICE - A lever having an end rotatably supported by a rack is disposed, a long groove is formed in either another end of the lever or a base chassis and extends in a direction approximately perpendicular to a direction of transporting an optical pickup, a fulcrum member is disposed in either the base chassis or the other end and is rotatably and slidably engaged with the long groove, and to slide along the long groove when the optical pickup is transported, and a spring that always exerts a pushing force in a direction of rotating the lever with the other end being a fulcrum and with the end being a point of action to exert a pushing force of bringing the rack into contact a gear series upon the rack is disposed between a predetermined position of the base chassis and an intermediate position of the lever. | 08-12-2010 |
| 20110185376 | OPTICAL DISC FIXING DEVICE AND OPTICAL DISC DRIVE USING SAME - An optical disc fixing device and an optical disc drive using the optical disc fixing device are provided. The optical disc fixing device is configured for fixing an optical disc thereto. The optical disc defines a circular mounting hole at the center portion. The optical disc fixing device includes a cylindrical clamping chassis, at least one latching piece, at least one elastic member, and a control member. The clamping chassis is substantially the same shape as the mounting hole of the optical disc and has a peripheral sidewall. The at least one latching piece together with the at least one elastic member are assembled within the clamping chassis. The control member is releasably assembled to the clamping chassis for extending the at least one latching piece from the peripheral sidewall of the clamping chassis to hold the optical disc. | 07-28-2011 |
| 20120017224 | DISC PLAYER WITH LIGHT-SENSING TYPE LOADING MECHANISM - A disc player with light-sensing type loading mechanism includes a casing, a control board, a slide mechanism and a light-sensing element. The light-sensing element is adopted to serve as a switch controlling the slide mechanism to reciprocate between a loading area and a reading area. The disc to be loaded is detected by an optical manner instead of physical. The invention may increase durability of a disc player. | 01-19-2012 |
| 20120198485 | LASER HOLDER AND OPTICAL PICKUP PROVIDED WITH SAME - A laser holder is used for holding a semiconductor laser, and is obtained by working of a metal sheet. The laser holder is provided with a step formed by folding of a metal sheet; and a positioning holding section capable of holding the semiconductor laser in a positioned state using the step, the positioning holding section provided on the metal sheet. | 08-02-2012 |

| 20090031334 | VIBRATION DAMPING CARRIER FOR A DISK DRIVE - A vibration damping carrier for a disk drive. The carrier may be made of plastic and includes a pair of flexible rails securable to mounting holes in a raised pad on opposing sides of a disk drive housing. Each flexible rail secures one or more sets of a spring and a protuberance in transverse alignment with the spring. Each spring is outwardly extending for engaging opposing walls of a chassis bay and each protuberance is inwardly extending into engagement with the rigid housing. When the disk drive housing and flexible rails are positioned within the chassis bay, each spring and protuberance set is transversely compressed. Typically, the disk drive housing and the chassis bay are rectangular such that the spring and protuberance are transversely compressed. The protuberances provide localized reinforcement of the rails and prevent any significant flexing from occurring. | 01-29-2009 |
