Abstract

A sheet storing apparatus capable of discharging sheets supplied by an image forming apparatus either face-up or face-down. The sheet storing apparatus comprises: forward/reverse rotary rollers for delivering a sheet in a direction leaving the image forming apparatus behind as well as in a direction contrary to the former, sheet discharging rotary rollers for discharging the sheet out of the sheet storing apparatus on a storing tray, a first delivery path for discharging the sheet face-up, a second delivery path for delivering the sheet in the direction leaving the image forming apparatus behind, a third delivery path for discharging the sheet face-down, switching guides for diverting the sheet either to the first or second delivery path, a sheet detecting sensor, disposed on a common path formed by joining the first and third paths, for detecting the sheet, a discharge mode controller for selecting either the face-up discharge mode or the face-down discharge mode according to sheet detections by said sheet detecting sensor, and a rotatable top cover for supporting components of said delivery paths' guide surfaces and said switching guides and for exposing said delivery paths.
