Abstract: An automatic document feeder includes a sheet input tray, a transfer channel, a sheet pick-up module, a retard roller, a thickness detecting module and a controlling unit. When the sheet pick-up module is driven, the documents placed on the sheet input tray are fed into the transfer channel. The thickness detecting module is used for detecting a thickness of the documents. The controlling unit is used for judging whether a multiple-feeding event occurs. In a case that the multiple-feeding event occurs, the sheet pick-up module is reversely rotated such that the documents are returned to the sheet input tray. When the sheet pick-up module is reversely rotated, the retard roller provides a lower frictional force, so that the documents are allowed to be returned to the sheet input tray.

Abstract: An automatic document feeder includes a transfer channel, a pick-up module and a thickness detecting module. The thickness detecting module includes a detecting member, a transmission member and an optical displacement sensing member. By the pick-up module, a sheet article is fed into the transfer channel. When the sheet article is transported across the detecting member, the sheet article is sustained against the detecting member, so that the detecting member is moved. The transmission member is connected to the detecting member. As the detecting member is moved, the transmission member generates a displacement amount. The optical displacement sensing member is used for detecting a displacement amount of the transmission member, thereby acquiring the thickness of the sheet article.

Abstract: A thickness detecting mechanism is provided for detecting a thickness of a to-be-measured article. The thickness detecting mechanism includes a detecting arm and an optical displacement sensing module. The detecting arm is moved as the to-be-measured article is sustained against the detecting arm. The detecting arm includes a surface. The optical displacement sensing module detects the surface of the detecting arm when the detecting arm is respectively located in a first position and a second position. According to the displacement amount of the detecting arm from the first position to the second position, the thickness of the to-be-measured article is acquired.

The controlling module is electrically connected to the speed-variable motor and the thickness sensor, and includes a look-up table. The thickness sensor is used for detecting a thickness of an article fed into the shredder. The speed-variable motor is operated at a variable rotating speed. When a thickness-detecting signal is received by the controlling module, the operating data corresponding to the thickness-detecting signal are searched from the look-up table and outputted from the controlling module to the speed-variable motor, thereby controlling the speed-variable motor to be operated at a proper rotating speed. As a consequence, a power-saving purpose is achieved by the variable frequency controlling system.
