Paper discharge mechanism in sheet processing apparatus and image reading apparatus having the same

摘要

In a sheet discharge mechanism for enabling a wide range of sheets stored on a sheet discharge tray from a processing section, a brake lever for reducing a velocity of a sheet fed from a sheet discharge outlet is held detachably relative to an attachment frame above the sheet discharge tray, and it is possible to select whether brake action is made corresponding to sheet discharge conditions. A sheet discharge mechanism includes a sheet discharge path having a sheet discharge outlet, a sheet discharge tray disposed on the downstream side of the sheet discharge outlet with a level difference, and a brake section of a sheet carried out at the sheet discharge outlet, wherein the brake section includes a lever member in which its base end portion is axially supported by an attachment frame, and its front end portion moves up and down corresponding to a load amount of sheets.
