Abstract
A sheet conveyance device includes a loading section, a first conveyance member a separation section, a first sheet length detector to detect whether the sheet is longer than a predetermined length slightly longer than a specific sheet size in the sheet conveyance direction, a trailing-edge detector disposed downstream from the separation section, a leading-edge detector disposed downstream from the trailing-edge detector a distance smaller than the specific sheet size and from the first conveyance member a distance longer than the specific sheet size, and a controller. When the sheet is equal to or greater than the predetermined length, the controller starts sheet feeding when the trailing-edge detector detects the trailing edge of the sheet, and when the sheet is smaller than that, the controller starts sheet feeding when either the leading-edge detector detects the leading edge of the sheet or the trailing-edge detector detects the trailing edge thereof.
