Abstract
The invention relates to a document-tray driven apparatus for a photo drive for reading information off a transparent sheet or a reflective sheet. The invention mainly comprises a paper feeding device, a driving device, a lower illumination device, an upper illumination device and a photoelectric converting device. The exposure of the original sheet depends on the motion of the paper feeding device. As the paper feeding device is moving, the scanning process takes place simultaneously. This design allows all other optical members to fix on the housing. Thus, it makes the light path easier to control and the quality of the image scanned will be improved thereby. Moreover, since the driving device is installed at a single side of the housing, the space inside the housing can be utilized more efficiently.
