摘要： A scanning apparatus includes a scanning module. The scanning module includes plural light emitting diodes, a porous reflective plate with plural openings, and a reflective element. When the scanning apparatus starts scanning a document, the light beams emitted by the light emitting diodes are directed to the porous reflective plate. A portion of light beams reflected by the porous reflective plate are defined as reflected light beams. The light beams penetrating through the openings are diffracted to be diffractive penetrated light beams. The reflected light beams reflected by the reflective element and the diffractive penetrated light beams are projected on the document, so that enhanced uniform illumination efficacy is achieved.

摘要： A retard roller of an automatic document feeder provides a frictional force to separate plural documents from each other. The retard roller can provide a first damping torque and a second damping torque with different directions. The second damping torque is smaller than the first damping torque. As such, the frictional force exerted on the document is reduced for returning the document out of the automatic document feeder. A retard roller module having such a retard roller is also provided.

摘要： A printing device includes a casing, a ribbon cartridge, a print head, a first driving motor and a second driving motor. The print head is disposed under the ribbon cartridge. A rotating center axial line of the ribbon wheel of the ribbon cartridge passes through a bottom of the casing. The print head has at least firing pin for colliding the ink ribbon, so that the ink containing in the ink ribbon is printed on a paper sheet. The first driving motor is used for driving rotation of the ribbon wheel. The second driving motor is used for driving movement of the print head between a first sidewall and a second sidewall of the casing. Consequently, the overall height and the cost of the printing device are reduced.

摘要： A contact image sensor module for scanning a document includes a light source, a photosensing array and a lens assembly. The light source emits a light beam to the document, thereby generating an optical signal. The photosensing array is used for converting the optical signal into an electronic signal. The lens assembly is used for focusing the optical signal reflected from the document and imaging the optical signal onto the photosensing array. The photosensing array includes a first photosensing element with a first width and a second photosensing element with a second width. The first width is greater than the second width.

摘要： A mechanism for confining a flat flexible cable of an image scanner in position is provided. The flat flexible cable is electrically connected between a circuit board and a carriage and bends differentially with the movement of the carriage relative to the circuit board under a scanning platform. The mechanism includes a confining member disposed between a first portion of the flat flexible cable and the scanning platform for isolating the flat flexible cable from the scanning platform. The confining member changes states and bends differentially with the movement of the carriage relative to the circuit board under the scanning platform, and has a bending resistance greater than that of the flat flexible cable. Accordingly, the confining member is kept at least a certain clearance from the scanning platform while confining the first portion of the flat flexible cable thereunder.
