Abstract: A transmission mechanism for switching output powers includes first to fourth transmission gears, first and second power-connecting members and a driving mechanism. The first power-connecting member coaxially disposed between the first and second transmission gears is moved axially, and connects the first and second transmission gears together to transmit power to the second transmission gear. The second power-connecting member coaxially disposed between the third and fourth transmission gears is moved axially and connects the third and fourth transmission gears together to transmit power to the fourth transmission gear. The driving mechanism synchronously drives the first and second power-connecting members to move axially to selectively connect the first transmission gear to the second transmission gear, or connect the third transmission gear to the fourth transmission gear. A scanning apparatus using the transmission mechanism is also disclosed.

Abstract: 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.

Abstract: A sheet feeder having a sheet-stopping function includes a rotating shaft, a sheet-input roller and a sheet-stopping mechanism. The rotating shaft is rotatable in a first direction and a second direction. The sheet-input roller mounted on the rotating shaft feeds a sheet. The sheet-stopping mechanism is driven by the rotating shaft to switch between a sheet-stopping state and a non-sheet-stopping state. The rotating shaft is rotated in the first direction to enable the sheet-stopping mechanism to enter the non-sheet-stopping state and allow the sheet to come into contact with the sheet-input roller. The rotating shaft is rotated in the second direction to enable the sheet-stopping mechanism to enter the sheet-stopping state and block up a passage to the sheet-input roller. A scan apparatus using the sheet feeder is also disclosed.

The sheet-feeding mechanism transports a first sheet and a second sheet successively through the sheet passageway. The rotatable gap sensor is rotated by movement of the first sheet and the second sheet for the detection of the presence of the first sheet and the second sheet. The rotatable gap sensor generates a plurality of state signals with respect to rotating states of the rotatable gap sensor.
