20100306790 | OPTICAL DISC DRIVE - An optical disc drive including a chassis, a circuit board and a traverse is provided. The traverse includes a carrier, a pick-up head module, a spindle motor module and a flexible flat cable. The carrier has an opening. The pick-up head module is movably disposed in the opening. The spindle motor module disposed on the carrier is located at one side of the pick-up head module. The flexible flat cable disposed in the opening has two connection ends respectively connected to the pick-up head module and the circuit board. The pick-up head module located at a first position enables the flexible flat cable to have a bending portion protruding towards a direction opposite to the position of the spindle motor module. The pick-up head module located at a second position extends the bending portion. The first position is closer to the spindle motor module than the second position is. | 12-02-2010 |
20110099566 | OPTICAL DISC DRIVE - An optical disc drive includes a main body, a cover, an extension, and an elastic element. The cover includes a pivoting portion and is pivotably connected to the main body via the pivoting portion. The extension is connected to the pivoting portion. The cover is adapted for pivoting relative to the main body to drive the extension to move along a movement path. The elastic element is disposed on the main body and includes two first limiting portions opposite to each other. The movement path extends through a gap between the two first limiting portions. A distance between the two first limiting portions is smaller than an outer diameter of the extension. | 04-28-2011 |
20120227062 | OPTICAL PICK-UP HEAD MODULE - An optical pick-up head module includes a base, an optical pick-up head adjusting mechanism, two guiding rods, a spring and an optical pick-up head slidably disposed on the guiding rods. The optical pick-up head adjusting mechanism includes a protrusion, a pillar and an adjusting element. The protrusion connected to the base has a sliding slot. The pillar having first and second flat surfaces is slidably disposed in the sliding slot. The first flat surface contacts an inner wall of the sliding slot. The adjusting element is screwed on the base. The spring disposed on the base pushes the pillar to contact the adjusting element by the second flat surface. When the adjusting element is rotated, the adjusting element pushes the pillar toward the base. | 09-06-2012 |
20130283300 | TRAY LOCKING DEVICE OF OPTICAL DISC DRIVE - A tray locking device of an optical disc drive adapted to lock and release a tray is provided. The optical disc drive has an optical head engaged with a lead screw and driven to move by the lead screw. The tray locking device includes a pushing member disposed on the optical head, a latching hook for latching and releasing a pin, and a transmission assembly disposed between the pushing member and the latching hook. The transmission assembly includes first and second lever elements. The first lever element pivoted in the tray has a slide slot having a first protrusion portion therein. The second lever element has a second protrusion portion adapted to move within the slide slot. When the tray is to be ejected, the lead screw drives the pushing member to push the second lever element, such that the second protrusion portion is aligned with the first protrusion portion. | 10-24-2013 |
20130298144 | TRAY LOCKING DEVICE FOR OPTICAL DISC DRIVE - A tray locking device adapted to an optical disc drive for locking and releasing a tray is provided. The optical disc drive has an optical head connected to a lead screw and driven to move by the lead screw. The tray locking device includes a pushing member driven to move by the lead screw, a latching hook for locking and releasing a protruding pin, and a transmission assembly configured between the pushing member and the latching hook. The transmission assembly includes a first rod and a second rod movably configured in the tray. The first rod has a first driving portion, and the second rod has a second driving portion. When the transmission assembly is located at an initial position, the first driving portion is located on a moving path of the pushing member, while the second driving portion is not located on the moving path of the pushing member. | 11-07-2013 |
20140016106 | Light Source Module and Micro Projector Using the Same - A light-source module including a light-source holder, a light source, a collimator lens holder, a collimator lens, a fasten member and an elastic member is suitable for being disposed in a housing. The light-source holder having a convex portion engaged with a concave portion of the housing is adapted to rotate about an axis. The light source disposed in the light-source holder emits a light beam along a beam path. The collimator lens is disposed in the collimator lens holder disposed in the light source holder on the beam path and a distance is maintained between the light source and the collimator lens. When fastened into a positioning hole of the housing, the fasten member pushes the light-source holder to rotate about the axis and the light-source holder presses the elastic member leaned against the light-source holder. | 01-16-2014 |
20140152963 | ALIGNING METHOD AND OPTICAL APPARATUS - An aligning method is provided. The aligning method includes: fixing a plurality of lenses and a beam combining unit in a fixing base; respectively disposing a plurality of light emitting units in a plurality of holders; leaning the holders on the fixing base, and respectively corresponding locations of the light emitting units to locations of the lenses; turning on the light emitting units, and enabling the light beams respectively emitted by the light emitting units to be combined by the beam combining unit after respectively passing through the lenses; and respectively adjusting positions of at least part of the light emitting units by using at least one jig to respectively hold the at least part of the light emitting units until an overlapping degree of the light beams combined by the beam combining unit matches a preset requirement. In addition, an optical apparatus is provided as well. | 06-05-2014 |
20140160448 | OPTICAL MODULE USED IN PROJECTION DEVICE - An optical module used in a projection device is provided. The optical module includes a base and a filter mirror. The base has an inclined leaning surface and a sidewall surface. The sidewall surface is located at a periphery of the base and forms a through hole along a direction. The inclined leaning surface is extended from the sidewall surface and an inclined angle is formed between the inclined leaning surface and the direction. The filter mirror is disposed on the inclined leaning surface. | 06-12-2014 |
