The present invention is related to a scanning device for scanning documents, comprises a flat-bed scanning glass; a contact image sensor arranged above the flat-bed scanning glass separately to form a scanning path therebetween, a bottom surface of the contact image sensor being arranged with a protecting glass, a middle area of the protecting glass being configured as a scanning area, and a chamfer being arranged at the bottom surface of the protecting glass at a downstream position relative to the scanning area. Hence the dust of documents in this invention would be stacked in the chamfer during the scanning process temporarily and then be wiped away by the document itself, so as to assure the dust would not be stacked in the scanning area. The scanning device in this invention is capable to maintain the scanning quality without clearing the dust even after scanned a massive quantity of documents.

Scanner

A paper separation mechanism includes a separation roller assembly, a one-way clutch module, a transmission gear assembly connected with and driving the one-way clutch module, a driving motor for driving the transmission gear assembly, and a locking module. The separation roller assembly includes a separation shaft, a separation roller fastened around the separation shaft, and a pickup roller disposed to the separation roller. The one-way clutch module includes a gear shaft, and a one-way clutch mounted around the gear shaft. The locking module includes a swing arm, a hooking portion fastened to a bottom of the swing arm, a blocking portion fastened under the swing arm, and a spring disposed to the bottom of the swing arm. One side of the swing arm is fastened to the gear shaft, the other side of the swing arm is fastened to the separation shaft.

Paper separation mechanism

A transmission device for an automatic document feeder includes a driving gear set driven by a driving motor, a first swing arm equipped with a first driving roller set, a second swing arm equipped with a second driving roller set, and a one-way gear set driven by the driving gear set to keep transmitting rollers rotating in the same direction. The first swing arm is driven by the driving gear set and swingable between a first position and a second position to mesh the first driving roller set with a pickup device or an output device. The second swing arm is driven by the driving gear set and swingable between a third position and a fourth position to mesh the second driving roller set with the pickup device or the output device. When the first swing arm swings toward the first position, the second arm swings toward the fourth position, and when the first swing arm swings toward the second position, the second swing arm swings to the third position.

Transmission device for automatic document feeder

An automatic document feeder includes a paper transmitting path for guiding documents, a driving motor for providing driving torque, a pickup device disposed at the upstream of the paper transmitting path, an output device disposed at the downstream of the paper transmitting path and transmitting rollers disposed along the paper transmitting path for transmitting the documents, a first driving gear disposed between the pickup device and the output device, a transmitting gear swing arm equipped with a transmitting gear set and axially hinged with the first driving gear to swing according to the driving torque between a first position meshing the transmitting gear set with the pickup device and a second position idling the transmitting gear set, an actuator connected with the output device and a braking device disposed on the output device for locking the transmitting gear swing arm according to the position of the output device.

Automatic document feeder

A transmission device of automatic document feeder includes a transmission gear assembly, a pickup transmission gear assembly, a paper-feed transmission gear assembly, a correction transmission gear assembly, a pressure transmission gear assembly and a turn-over transmission gear assembly. The transmission gear assembly includes a transmission roller, a first drive gear and a second drive gear. The pickup transmission gear assembly includes a pickup drive gear, a pickup swing arm and a pickup auxiliary swing arm. The paper-feed transmission gear assembly driven by the transmission gear assembly includes a paper-feed reverse gear and a paper-feed swing arm. And the correction transmission gear assembly and the paper-feed transmission gear assembly rotate towards the same direction. The pressure transmission gear assembly includes a pressure swing arm and a pressure actuating gear. The turn-over transmission gear assembly is driven by the first drive gear of the transmission gear assembly.
