Abstract
A sheet takeout device includes a takeout belt brought into contact with a sheet set in a takeout position to generate negative pressure to adsorb the sheet, and traveled in a direction of an arrow T, and a separation roller which separates second and following sheets associatively taken out with the sheet. Triggered by detection of its leading end at a second sensor, an opposite-direction separation force is applied to the sheet to be conveyed via the separation roller.
