Removable processing cartridge for electrostatographic reproducing apparatus

摘要

An electrostatographic reproducing apparatus using a removable processing cartridge containing at least one electrostatographic processing unit together with a cartridge mounting means to the main frame of the reproducing apparatus and cartridge positioning means is described. The cartridge positioning means comprises a pair of elastomeric loops adapted to engage a frame member of the reproducing apparatus with a compression spring action to thereby maintain the cartridge in its operational position. The loops are of sufficient size and shape that they may be used as handles to manually extract the cartridge from the reproducing apparatus. In the specific embodiment the elastomeric loops are fastened to the top of a cartridge at one end thereof which engages with a bottom of the upper frame portion of a clam-shell type machine when it is pivoted to the closed position thereby maintaining the cartridge in its operational position.
