Abstract
Abstract In a device for storing printings, film sheets or similar recording media driven out or an image forming apparatus, bins are each inclined from a top sheet inlet thereof to a bottom sheet outlet thereof. When all the bins are full, such a condition is reported to users. Users having left sheets in the trays for a long period of time are alerted by a warning message. Sheets become needless for users can be automatically disposed of by commands from user stations. A user passes an I.D. card through a card reader to enter an I.D. number, opening a bin corresponding to the I.D. number, dropping the sheet onto a fence for user access.
