Abstract: A transceiver module is used in an optical fiber communications system. The optical fiber communications system includes a housing, a connector for connecting with the housing, an optical sub assembly (OSA) installed within the connector for receiving or emitting optical signals, a printed circuit board (PCB) installed within the housing for processing photoelectric signals, and a clipping device disposed within the housing for fixing the OSA so that the OSA is electrically connected with the PCB.

Abstract: A low voltage bobbin includes a core portion, a base portion, a plurality of insertion pins formed on an outer wall of the base portion, and a wire winding rod axially extending from each of the insertion pin. The thickness of portion of the outer wall of the base portion that is corresponding to each of the plurality of insertion pins is thinned down, each of the wire winding rod has a descending diameter from a root end to a free distal end of the wire winding rod.

Abstract: A DVD player with card reader of the present invention comprises a DVD player, an adapting interface and a card reader. The audio and video data, originally played by the computer, DSC or MP3 player, are accessed by a single DVD player with card reader. The audio and video data can be produced to television or audio set by the DVD player of the present invention.

Abstract: A parallel transmission device for reflection means and scanning means of a scanner, comprises fixing stage, reflection means, scanning means, fixing module, belt wheel, idle wheel, belt, tight wire, and driving means, wherein the reflection means is driven by the belt and can drive the scanning means by the tight wire to ensure that the scanning means and reflection means has a parallel movement therebetween, and has a speed ratio 2:1, i.e. the reflection means moves only half of the distance of the scanning means, thus reducing the space reserved for the movement of the reflection means and saving the internal space of the scanner.

Abstract: A type of service station wiping mechanism for a printing unit, including a fixing seat that is fitted at one end of the printing unit. On said fixing seat is fitted a solenoid and on said solenoid is a spindle. One end of said spindle is joined to a crank, and on the crank is a pushing tapered plane, when the crank moves horizontally in the fixing seat is a wiping pad seat which will move vertically. On said wiping pad seat is fitted a wiping pad. The lower end of the wiping pad seat is resting against the pushing tapered plane on the crank. The solenoid drives the spindle to move the crank and control the wiping pad seat and the wiping pad to move up or down.

Abstract: A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a first roller and a second roller, including a gear transmission mechanism, a first roller having a driven gear set at one end, and a second roller having a driven gear set at one end, wherein the gear transmission mechanism includes a motor, a rounded seat raised from the machine base, a drive gear mounted on the rounded seat and coupled to the motor, a first annular gear holder and a second annular gear holder revolvably mounted around the rounded seat and having a respective upright gear shaft, a crank turned about a pivot on the machine base and having an upright gear shaft at the free end, a first planet gear revolvably mounted around the gear shaft of the first annular gear holder and driven by the drive gear to turn the driven gear set of the first roller, a second planet gear revolvably mounted around the upright gear shaft of the crank and forced by the drive gear to turn t

Abstract: A transmission mechanism is installed in a machine and driven by a motor to pick up and feed paper. The mechanism includes a transmission gear and a return gear turned by a motor through a reduction gear train, a rocker turned with the transmission gear to move a rocker gear, an idle wheel, a transmission shaft covered with a rubber roll for feeding paper, a paper feeding gear wheel mounted on one end of a transmission shaft and meshed with the return gear, a first paper pick up gear having a peripheral surface section, a second paper pick up gear turned with the first paper pick up gear and having a peripheral surface section, a rubber cam synchronously turned with the first and second paper pick up gears, wherein when the motor is turned in one direction, the rocker is moved rightwards to force the rocker gear into mesh with the first paper pick up gear.

Abstract: A transmission unit mounted on the machine base of an office automation machine and covered with a cover and controlled to turn a first roller and a second roller, including a gear transmission mechanism, a first roller transmission mechanism driven and a second roller transmission mechanism respectively driven by the gear transmission mechanism to turn the rollers, wherein the gear transmission mechanism includes a motor, a rounded seat raised from the machine base, a drive gear mounted on the rounded seat and coupled to the motor, an annular gear holder revolvably mounted around the rounded seat and having an upright gear shaft, an upright axle raised from the machine base adjacent to the rounded seat, a crank having a pivot hole at one end coupled to the upright axle and a gear shaft at an opposite end, a first planet gear revolvably mounted around the gear shaft of the crank and driven by the drive gear to turn the first roller transmission mechanism, a second planet gear revolvably mounted around the gea

Abstract: A method of using a single pick-up head to read and store data in discs of different thickness, especially for CD (compact disc) and DVD (digital versatile disc), the method including the step of adjusting the electronic aperture ring to change the numerical aperture, and change the distance between the disc and the object lens subject to type of the disc used.
