Sheet-conveying apparatus

摘要

In a sheet-conveying apparatus, a first arm is disposed between a pick roller and a downstream end of a separator in a conveying direction in which a sheet is conveyed, and a second arm disposed downstream of the separator in the conveying direction. The first arm is movable from a non-detection position to a detection position when contacted by a sheet. The second arm is movable from a non-detection position to a detection position when contacted by a sheet. The sheet-conveying apparatus further includes a sensor configured to output a sensor-signal corresponding to positions of the first and second arms. The sensor outputs a first signal when at least one of the first arm and the second arm is disposed in the detection position. The sensor outputs a second signal other than the first signal when both the first and second arms are disposed in the detection positions.

主权项

1. A sheet-conveying apparatus comprising:
a tray configured to hold a plurality of sheets; a pick roller configured to convey a sheet from the tray; a control device configured to control the pick roller; a separator disposed downstream of the pick roller in a conveying direction in which a sheet is conveyed, the separator being configured to separate a preceding sheet from a succeeding sheet when the preceding sheet and the succeeding sheet are conveyed by the pick roller in an overlapped state; a conveyer disposed downstream of the separator in the conveying direction and configured to convey a sheet in the conveying direction; a first arm disposed between the pick roller and a downstream end of the separator in the conveying direction, the first arm being configured to move from a non-detection position to a detection position when contacted by a sheet; a second arm disposed downstream of the separator in the conveying direction and configured to move from a non-detection position to a detection position when contacted by a sheet; and a sensor configured to output a sensor-signal corresponding to positions of the first arm and the second arm, the sensor outputting a first signal when at least one of the first arm and the second arm is disposed in the non-detection position, the sensor outputting a second signal other than the first signal when both the first arm and the second arm are disposed in the detection positions.
