Abstract:
A document feeder includes: a first conveyer that picks up sheets from a sheet bundle sheet by sheet, where rear edge of a preceding sheet overlaps front edge of a succeeding sheet; a second conveyer that conveys each sheet picked up by the first conveyer; a front edge sensor that is disposed on a conveyance path from the first conveyer to the second conveyer, and senses whether the sheet falls within a sensing range; and a shift unit that shifts, while the first and second conveyers convey the sheet, positional relation between the sheet and the front edge sensor by increasing distance therebetween in a direction crossing a sheet conveyance direction, such that the sheet falls outside the sensing range. When the preceding sheet falls outside the sensing range, the first conveyer picks up the succeeding sheet such that the front edge of the succeeding sheet enters the sensing range.

Claim (Index 2):
The document feeder of  claim 1 , wherein\n the first conveyer picks up each sheet in a first conveyance direction, the second conveyer conveys the sheet in a second conveyance direction that is not an extension of the first conveyance direction, the shift unit includes a conveyance guide that guides the sheet picked up by the first conveyer to the second conveyer along a first conveyance path passing through the sensing range, and after the sheet reaches the second conveyer, the shift unit shifts the positional relation by setting a higher conveyance speed of the second conveyer than a conveyance speed of the first conveyer such that the sheet is conveyed along a second conveyance path, the second conveyance path being shorter than the first conveyance path and not passing through the sensing range.
