Claim 1
Independent Claim
151 words
A removable processing cartridge (11) for an . electrostatographic reproducing apparatus comprising a frame assembly (37, 38) containing at least one electrostatographic processing unit (12) and means to mount said removable processing cartridge in a receiving mount in said reproducing apparatus, characterised in that the mounting means on the cartridge comprises a pair of mounting hinge slots (42), one on each side of one end of said cartridge which are positioned for cooperative engagement with a pair of locating pivot pins (68) located one on each side of the frame of the reproducing apparatus about which said cartridge may be pivoted and, a pair of mounting pins (40) one on each side of one end of said cartridge adjacent said mounting hinge slots which pins (40) are positioned for cooperative engagement with a pair of cartridge latch blocks (70) located one on each side of the frame of the reproducing apparatus.
Claim 2
Dependent Claim
151 words
A removable processing cartridge (11) for an . electrostatographic reproducing apparatus comprising a frame assembly (37, 38) containing at least one electrostatographic processing unit (12) and means to mount said removable processing cartridge in a receiving mount in said reproducing apparatus, characterised in that the mounting means on the cartridge comprises a pair of mounting hinge slots (42), one on each side of one end of said cartridge which are positioned for cooperative engagement with a pair of locating pivot pins (68) located one on each side of the frame of the reproducing apparatus about which said cartridge may be pivoted and, a pair of mounting pins (40) one on each side of one end of said cartridge adjacent said mounting hinge slots which pins (40) are positioned for cooperative engagement with a pair of cartridge latch blocks (70) located one on each side of the frame of the reproducing apparatus.
Claim 3
Dependent Claim
17 words
The cartridge of Claim 1, wherein said at least one processing unit includes a photoreceptor belt (12).
Claim 4
Dependent Claim
26 words
The cartridge of Claim 2, wherein said pair of mounting pins (40) comprises the mounting shaft of a support roll (43) for the photoreceptor belt (12).
Claim 5
Dependent Claim
25 words
The cartridge of Claim 3, wherein said mounting shaft is stationary and said support roll (43) is a driven transport for the photoreceptor belt (12).
Claim 6
Dependent Claim
64 words
The cartridge of any one of Claims 2 to 4, further including a corona charging device (64), an exposure slot (49) for exposing the charged photoreceptor belt (12) and a drive gear (46) mounted on one end of said photoreceptor support roll (43) which engages with the main drive of the apparatus when the cartridge is in said reproducing apparatus in its operative position.
Claim 7
Dependent Claim
21 words
Electrostatographic reproducing apparatus comprising a main frame, and a removable processing cartridge according to any one of Claims 1 to 5.
Claim 8
Dependent Claim
140 words
The apparatus of Claim 6, wherein each of said cartridge latch blocks (70) has an arcuate slot (74) therein defining a stationary inner guide -surface (75) and a curved outer deflectable cantilever spring arm (76), said slots terminating at its lower portion in a cartridge lock (77) for said cartridge mounting pins (40) and wherein when said cartridge (11) is initially inserted into said apparatus with said cartridge mounting hinge slot (42) resting on said main frame locating pivot pins (68) said cartridge mounting pins (40) engage the upper end of said curved outer deflectable cantilever spring arm (76) and as said cartridge is pivoted about said locating pivot pins (68) said spring arm (76) provides an interference for said cartridge mounting pins (40) and is deflected thereby providing a counterbalance to said cartridge as it is lowered into position.
Claim 9
Dependent Claim
52 words
The apparatus of Claim 7, wherein said cartridge lock (77) comprises a circular portion which accommodates the cartridge mounting pins (40) when in position permitting said cantilever spring arm (76) to return to its undeflected position when said mounting pins are in said circular portion (77) thereby locking said cartridge in position.
Claim 10
Dependent Claim
23 words
The apparatus of Claim 8, wherein said spring arm (76) has a stop member (78) to laterally maintain the spring arm in position.
Claim 11
Dependent Claim
67 words
The apparatus of Claim 6, wherein said main frame comprises a lower frame portion (32) and an upper frame portion (33) pivotal about one end in clam-shell fashion and wherein said cartridge mounting means are attached to said lower frame portion and said cartridge can be inserted from the top into said cartridge mounting means only when said upper frame portion is pivoted to an open position.
