A sheet collection apparatus has a stacking portion to stack mails in the standing position, a back-up plate in contact with one end of stacked mails in the stacked direction, and take-in rollers arranged at the positions contacting the other end of stacked mails. The take-in rollers are rotated at a slower peripheral speed than the conveying speed of mails taken in the stacking portion.
