Photo-pressure sensitive sheet cartridge

摘要

A photo-pressure sensitive sheet cartridge includes: an outlet from which a photo-pressure sensitive sheet is drawn out; a lid which closes the outlet in order to exclude the outer light; and an opening and closing lever for operating the lid to be opened or closed. When a sheet of photo-pressure sensitive paper is drawn out of this cartridge, the lid is opened in order to prevent the microcapsules on the sheet from being ruptured by pressure. While the photo-pressure sensitive sheet outside the cartridge is being exposed to light on a determined area in the copying machine, the lid is closed in order to prevent light from entering the cartridge.
