Abstract
An apparatus for holding a contact image sensor of a scanning system includes a supporting shaft and an elastic element. The supporting shaft is set through a holder and contact the contact image sensor. The elastic element contains a spring. The spring is positioned outside the holder and provides a force to the supporting shaft for pushing the contact image sensor upwardly. In this case, the contact image sensor stays close to a document plate to conduct scanning processes. Since the spring is outside the holder, the variation of holder due to manufacturing would not affect the force from the spring. Thus balanced forces are generated by the springs, further avoiding the situation of the contact image sensor jammed during scanning processes.
