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.
A removable processing cartridge for an electrostatographic reproducing apparatus comprising a cartridge frame assembly containing at least one electrostatographic processing unit, means to mount said cartridge about end thereof to a receiving mount in said reproducing apparatus and positioning means near the opposite end of said cartridge, said positioning means comprising elastomeric loops adapted to engage a frame member of said reproducing apparatus in a compression spring action to thereby maintain the cartridge in its operational position, said loops being of sufficient size and shape that they may be used as handles to manually extract the cartridge from said reproducing apparatus.
An electrostatographic reproducing apparatus comprising a main frame and a removable processing cartridge comprising a frame assembly containing at least one electrostatographic processing unit, means to mount sasid cartridge to a receiving mount in said reproducing apparatus about one end thereof, said cartridge frame assembly including positioning means near the opposite end of said cartridge said positioning means, comprising elastomeric loops adapted to engage a frame member of said reproducing apparatus in a compression spring action to thereby maintain the cartridge in its operational position, said loops being of sufficient size and shape that they may be used as handles to manually extract the cartridge from said reproducing apparatus.
