Abstract
Abstract A registration apparatus for a reproducing machine includes a resilient means which cooperates with a stop member to control the path of a sheet as it is intercepted by the stop member. Preferably the resilient member also operates to strip the sheet from the stop member as the stop member moves out of the sheet path.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
In a reproducing apparatus comprising; means for forming an image on a sheet; means for propelling a sheet along a path to said image forming means; means for registering the sheet with respect to said image forming means, said registering means comprising: a stop member for intercepting an edge of said sheet, said stop member including a stop face and a chute portion; and means for moving said stop member either into sheet blocking relationship in said path, or out of said sheet blocking relationship; and a guide member for supporting said sheet along said path at a position adjacent said stop member; the improvement wherein, said registering means further includes: a resilient means for urging said sheet against said guide member as it is intercepted by said stop face, said resilient member being mounted to said chute portion of said stop member with a free end thereof adjacent said stop face (means).
Claim 2
Dependent Claim
153 words
In a reproducing apparatus comprising; means for forming an image on a sheet; means for propelling a sheet along a path to said image forming means; means for registering the sheet with respect to said image forming means, said registering means comprising: a stop member for intercepting an edge of said sheet, said stop member including a stop face and a chute portion; and means for moving said stop member either into sheet blocking relationship in said path, or out of said sheet blocking relationship; and a guide member for supporting said sheet along said path at a position adjacent said stop member; the improvement wherein, said registering means further includes: a resilient means for urging said sheet against said guide member as it is intercepted by said stop face, said resilient member being mounted to said chute portion of said stop member with a free end thereof adjacent said stop face (means).
Claim 3
Dependent Claim
31 words
An apparatus as in claim 1, wherein said resilient means is also operative to strip a sheet from said stop member as it is moved out of said sheet blocking relationship.
Claim 4
Dependent Claim
47 words
An apparatus as in claim 2, wherein said means for moving said stop member comprises; means for pivotally supporting said stop member so that when said stop member moves out of said sheet blocking position, it moves in a direction in which said sheet is being propelled.
Claim 5
Dependent Claim
22 words
An apparatus as in claim 2, wherein said resilient means comprises a resilient member mounted in cantilevered fashion to said stop member.
Claim 6
Dependent Claim
14 words
An apparatus as in claim 1, wherein said resilient member comprises a strip-like member.
Claim 7
Dependent Claim
27 words
An apparatus as in claim 5, wherein said guide member is positioned below said sheet and wherein said stop and resilient members are arranged above said sheet.
Claim 8
Dependent Claim
77 words
An apparatus as in claim 6, wherein said means for forming an image on said sheet comprises: an imaging surface arranged for movement; means for forming an electrostatic image on said imaging surface; means for developing said electrostatic image to render it visible; and means for transferring said visible image to said sheet, and wherein said registering means is arranged to position said sheet along said path in a timed relationship with respect to said transferring means.
Claim 9
Dependent Claim
23 words
An apparatus as in claim 1, wherein said resilient means is also operative to decelerate said sheet as it approaches said stop member.
