Abstract
A sheet conveyance device includes a loading section, a sheet feeding unit, a separation section disposed downstream in a sheet conveyance direction from the sheet feeding unit, a conveyance member to transport a sheet separated by the separation section, a trailing-edge detector disposed at a first conveyance distance (L1) downstream from a separation position (Ab) and including a rotary follower and a rotation detector, a first leading-edge detector disposed downstream from the trailing-edge detector, and a controller. The trailing-edge detector A detects a sheet length in the sheet conveyance direction. The controller causes the sheet feeding unit to start sheet feeding in response to detection of the leading edge of the sheet by the first leading-edge detector when the detected sheet length equals a predetermined reference length and in other cases in response to detection of the trailing edge of the sheet by the trailing-edge detector.
