A four-direction adjustable optical module including a carriage and a CCD module is disclosed. The carriage includes a coupling window for coupling with the CCD module. Each of the two sides of the CCD module includes a screw hole and an elastic device. The elastic device slightly protrudes from the surface of the coupling window. While the CCD module and the coupling window are coupled, screws are employed to screw through the CCD module and into the screw holes of the coupling windows. Therefore, the elastic devices deform by the stress from the CCD module. By adjusting the tightness of the screws, the orientation of the CCD module rotating on the Z axis can be calibrated. Thus, the adjustable optical module of the invention can be calibrated at least in four directions.

Four-direction adjustable optical module

An image scanner capable of scanning reflective and penetrative documents is provided. The image scanner includes a housing, a supporting base mounted in the housing and moving along the first direction while scanning, a first scanning platform mounted on the housing for placing thereon the reflective document, a first light transmitting device mounted fixedly on the supporting base for focusing and transmitting light signal, a first photoelectric sensing element mounted fixedly on the supporting base for receiving the reflected light signal and converting the received light signal into electric signal, a second scanning platform mounted in the housing for placing thereon the penetrative document, a second light transmitting device mounted fixedly on the supporting base for focusing and transmitting light signal, and a second photoelectric sensing element mounted fixedly on the supporting base for receiving the penetrating light signal and converting the penetrating light signal into electric signal.
