20110241278 | SHEET FEEDER AND SCAN APPARATUS WITH SHEET-STOPPING FUNCTION INDEPENDENT OF MOVEMENT OF PICK-UP MECHANISM - In a scan apparatus, a sheet feeder having a sheet-stopping function includes a rotating shaft, a sheet-input roller, a pick-up mechanism and a sheet-stopping mechanism. The pick-up mechanism, including a bracket mounted on the rotating shaft and a pick-up roller mounted on the bracket, picks up a sheet from a paper tray. The sheet-stopping mechanism, driven independent of movement of the bracket by the rotating shaft, switches between a sheet-stopping state and a sheet-non-stopping state. The rotating shaft rotates in a first direction to enable the sheet-stopping mechanism to enter the sheet-non-stopping state and rotates in a second direction to enable the sheet-stopping mechanism to enter the sheet-stopping state, in which a passage to the sheet-input roller is blocked up. | 10-06-2011 |
20130328261 | AUTOMATIC FEEDING APPARATUS WITH SHEET-INPUT ASSISTING MECHANISM - An automatic feeding apparatus includes a body and a sheet passage, a sheet-separation mechanism and a sheet-input assisting mechanism in the body.

The clutch gear is rotated rearward to be engaged with a gear rack of the presser at the first position and thereby drive the presser to move in a first direction. The clutch gear is rotated forward to move to the second position and disengaged from the gear rack of the presser. After being released, the presser moves in a second direction to press a sheet in front of a nip portion of the sheet-separation mechanism. | 12-12-2013 |
