Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

Abstract: An optical scanning module with linear CMOS image sensor (linear CMOSM) applied to scanners or multi-function printers is disclosed. The optical scanning module includes a light source for emitting light, a reflection mirror group, a focus lens group, and a linear CMOS image sensor having at least one linear CMOS image sensor unit and one A/D analog-digital converter. The light source can be a cold cathode fluorescent lamp (CCFL), a Xenon lamp or linear LED. Light emitted from the light source projects onto an object being scanned. Then the light reflected by the object being scanned becomes scanning light, passing through the reflection mirror group and the focus lens group and being focused on the linear CMOS image sensor for being converted into electrical signal. By A/D conversion of the linear CMOS image sensor unit in the linear CMOS image sensor, signal is sent out in USB or LVDS format so as to achieve high scanning speed, low distortion, large depth of focus and convenient transmission.

Abstract: A scanning module of the present invention includes a light source for illuminating a document. Light reflected by the document is incident to a first and a second mirror provided in a pair. The two mirrors reflect the light a plurality of times therebetween and then output it as light reflected from the first mirror. Subsequently, a third and a fourth mirror sequentially reflect the light along a path including a lens. A fifth mirror reflects the light incident thereto from the lens. A linear sensor is spaced from the fifth mirror by a preselected distance such that the light passed through the lens is focused on the linear sensor. The first and second mirrors are adjustable in position on a path, extending from the document to the first mirror, while maintaining a positional relation therebetween.

Abstract: A positioning mechanism for reflectors in a scanner is capable of tool-less assembling and precise positioning. The mechanism mainly includes a carrier, some angular positioning members, and resilient arms. The carrier is a plate-like member for mounting an optical assembly. The angular positioning members are mounted on the carrier and formed with cutoffs of supporting surfaces. The resilient arms extend from the carrier to outer sides of the supporting surfaces of the angular positioning members. The clearance of the end of resilient arm to the supporting surface is less than the thickness of the reflector to position the reflector simply, easily and precisely.
