Abstract
Abstract A finisher for use with a copier, laser printer or similar image forming apparatus and having a function of sorting or stacking sheets sequentially driven out of the apparatus and a function of stapling each stack of such sheets. A plurality of bins are sequentially moved to a position where the bins face the sheet outlet of the apparatus one at a time. A particular pair of the bins define a sheet inlet for receiving the sheets coming out of the sheet outlet one at a time. The sheets are distributed to the bins via the inlet to be stacked on the bins. A sheet stack is pulled out of each bin by a sheet stack moving device, bound at a staple position by a stapler, and then returned to the bin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
246 words
A finisher for use with an image forming apparatus for distributing a plurality of recorded sheets sequentially coming out of said apparatus through an outlet to a plurality of bins to stack said recorded sheets on said pularlity of bins, comprising: bin moving means for sequentially moving said plurality of bins to a predetermined position where said plurality of bins face said outlet; a bin inlet defined between, among said plurality of bins, an upper bin and a lower bin having been moved to said predetermined position for receiving the recorded sheets one at a time; stapling means for stapling the recorded sheets stacked on each of said plurality of bins at a staple position; and sheet stack moving means for pulling out a stack of the recorded sheets from each of said plurality of bins to said staple position, causing said stapling means to staple said stack, and then returning said stack to said bin; wherein said sheet stack moving means comprises: a first gripping member movable toward and away from each of said bins in a linear motion; a second gripping member rotatably mounted on said first gripping member; a cam follower in the form of a pin studded on one end of said second gripping member; and a cam groove along which said cam follower is movable due to said linear motion, whereby said second gripping member performs a sequence of movements for gripping the stack, moving said stack, and releasing said stack.
Claim 2
Dependent Claim

A finisher for use with an image forming apparatus for distributing a plurality of recorded sheets sequentially coming out of said apparatus through an outlet to a plurality of bins to stack said recorded sheets on said pularlity of bins, comprising: bin moving means for sequentially moving said plurality of bins to a predetermined position where said plurality of bins face said outlet; a bin inlet defined between, among said plurality of bins, an upper bin and a lower bin having been moved to said predetermined position for receiving the recorded sheets one at a time; stapling means for stapling the recorded sheets stacked on each of said plurality of bins at a staple position; and sheet stack moving means for pulling out a stack of the recorded sheets from each of said plurality of bins to said staple position, causing said stapling means to staple said stack, and then returning said stack to said bin; wherein said sheet stack moving means comprises: a first gripping member movable toward and away from each of said bins in a linear motion; a second gripping member rotatably mounted on said first gripping member; a cam follower in the form of a pin studded on one end of said second gripping member; and a cam groove along which said cam follower is movable due to said linear motion, whereby said second gripping member performs a sequence of movements for gripping the stack, moving said stack, and releasing said stack.
Claim 3
Dependent Claim
37 words
A finisher as claimed in claim 1, wherein said bin moving means comprises means for supporting only one end of said bins while said bin moving means sequentially moves said plurality of bins to said predetemined position.
Claim 4
Dependent Claim
30 words
A finisher as claimed in claim 2, wherein said bin moving means comprises a support member for guiding and supporting the other end of each of said plurality of bins.
Claim 5
Dependent Claim
40 words
