Abstract
Abstract A cartridge assembly including a processing cartridge removable therefrom for use with and insertion into an electrostatographic reproducing apparatus is provided. The assembly includes a cartridge frame together with at least one electrostatographic processing unit such as a photoreceptor belt which has a portion outwardly exposed relative to the cartridge for performing its processing function when inserted in the copier which is susceptible to deterioration or damage, a removable rigidly conformable protective sheath like member wrapped around the cartridge having around the periphery of one end protecting the insertion end of the cartridge one element of a two element coupling which is engagably mateable with the other element of the two element coupling at the cartridge insertion position of the copier and means to slidably urge the cartridge through the sheath into the reproducing machine when the coupling element on the end of the sheath is engagably mated with the coupling element on the copier whereby the processing cartridge may be inserted in the copier without deterioration or damage. In a preferred embodiment the two element coupling comprises a male lip around the periphery of the sheath which is engagable with a female coupling collar on the main apparatus and a lever is provided movable within a slot in the sheath actuatable from outside the sheath to urge the cartridge into the processing position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
178 words
An assembly including a processing cartridge removable therefrom for use with and insertion into an electrostatographic reproducing apparatus, said assembly comprising; a cartridge frame assembly supporting at least one electrostatographic processing unit having at least a portion thereof outwardly exposed relative to the cartridge for performing its processing function when inserted in said reproducing apparatus, said exposed portion being susceptible to deterioration or damage by so being exposed; a removable rigidly conformable protective sheath like member wrapped around said cartridge and containing said cartridge therein, said sheath like member having around the periphery of one end protecting the insertion end of the cartridge one element of a two element coupling which is engagably mateable with the other element of the two element coupling at the cartridge insertion portion of said reproducing apparatus; and means to slidably urge said cartridge through said sheath into said reproducing machine when said one element of said sheath is engagably mated with said coupling element on said reproducing apparatus, whereby said processing cartridge is inserted in said reproducing apparatus without deterioration or damage.
Claim 2
Dependent Claim
178 words
An assembly including a processing cartridge removable therefrom for use with and insertion into an electrostatographic reproducing apparatus, said assembly comprising; a cartridge frame assembly supporting at least one electrostatographic processing unit having at least a portion thereof outwardly exposed relative to the cartridge for performing its processing function when inserted in said reproducing apparatus, said exposed portion being susceptible to deterioration or damage by so being exposed; a removable rigidly conformable protective sheath like member wrapped around said cartridge and containing said cartridge therein, said sheath like member having around the periphery of one end protecting the insertion end of the cartridge one element of a two element coupling which is engagably mateable with the other element of the two element coupling at the cartridge insertion portion of said reproducing apparatus; and means to slidably urge said cartridge through said sheath into said reproducing machine when said one element of said sheath is engagably mated with said coupling element on said reproducing apparatus, whereby said processing cartridge is inserted in said reproducing apparatus without deterioration or damage.
Claim 3
Dependent Claim
