Abstract: A paper-feeding mechanism of an automatic document feeder includes a pick-up module, a supporting module and a paper stopping module. The pick-up module is used for picking an uppermost paper sheet from the stack of paper sheets and transporting the uppermost paper sheet into a passageway inside the automatic document feeder. The supporting module supports the pick-up module and is rotated to either ascend or descend the pick-up module, wherein the supporting module has a sustaining part on a sidewall thereof. When the supporting module and the pick-up module are downwardly rotated, the stopping plate is moved vertically to a paper-feeding position for allowing the uppermost paper sheet to be transported into the passageway. When the supporting module and the pick-up module are upwardly rotated, the stopping plate is moved vertically to a paper-stopping position for hindering the uppermost paper sheet from being transported into the passageway.

Abstract: A scanning module capable of finely tuning the optical length comprises a lamp tube, a base, a photosensitive substrate, and an adjustment unit. The lamp tube provides a required light source for a document to be scanned. The base has a reflective mirror set and a camera lens.

Abstract: The present invention provides a multi-resolution printing device, which includes a base-frequency clock generator and a control unit. The base-frequency clock generator is to generate only one base-frequency clock. The control unit includes a logic processor, a first frequency divider, a second frequency divider, and an external selector. Divisors of the first and second dividers are determined by resolution of the base-frequency clock and that of the desired printing clocks. While remainders of the base-frequency clock resolution divided by the desired printing clock resolutions are not zero, divisors of first and second frequency dividers are set to be the quotient and the quotient plus one; otherwise, divisors of first and second frequency dividers are all set to be the same quotient. The resolution of desired printing clock is obtained by executing the above procedure excursively.
