Abstract
A sheet discharging device has a conveying weight for pressing a conveyed sheet to a caterpillar belt. The pressing force of the weight is increased both when the sheet is discharged from the caterpillar belt to a placement tray, and when the sheet is switched back and conveyed to the bottom of the caterpillar belt. The pressing force of the weight is increased concurrently with the driving of a paddle provided at an outlet of the placement tray. The pressing force is increased by a rubber piece provided on a paddle driving shaft that rotates out of phase with the paddle, so as to engage and press the conveying weight at a predetermined time. The device is capable of reliably conveying a wide variety of sheets onto a tray and transferring the conveyed sheets to a predetermined tray position.
