Abstract
Abstract A movable divider wall means is resiliently supported to extend through a slot opening in a bottom wall and into contact with the top wall so as to define between one of its faces and one of the edges of a channel guide for documents an effective guide for documents of a narrower width defined by the wall and the opposed channel wall. The movable wall has a tapered top edge which tapers from a widely spaced leading edge to the flat top of the movable wall which abuts the top wall and is held into the top wall by resilient means. Documents of greater width may be inserted over the movable wall and passing documents will urge the movable wall downward to displace it and allow their passage. Guide means is preferably provided to direct documents of the second narrower width into the channel at a position after the beginning of the movable wall and from above the movable wall so that they do not tend to move the wall out of its position as they are introduced. In either case, suitable conveyor means pull the documents through the apparatus once they are introduced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
In a document handling device wherein position of the document is sensitive and at least two widths of document must be handled, the improvement comprising: a conveyor channel having upper and lower walls and lateral walls defining means at fixed width to align documents of a first width fitting snugly within the lateral walls; at least one movable divider wall means extending through one of the upper or lower walls and into contact with the other, over a distance large in comparison to channel thickness and having a channel defining wall surface spaced from a lateral wall defining means in order to accept and align narrower documents of a second width fitting snugly therebetween, said divider wall having a tapering leading edge in the direction of document movement over the wall providing a decreasing space between the wall with which it is in contact away from the document insertion end of the channel, resilient means urging the movable divider wall into the wall with which it makes contact and yielding to documents passing over the leading tapered edge of the movable wall; and conveyor means to engage a document inserted into the channel and pull the document through the channel while maintaining position of the document relative to at least one lateral wall defining the channel.
Claim 2
Dependent Claim
216 words
In a document handling device wherein position of the document is sensitive and at least two widths of document must be handled, the improvement comprising: a conveyor channel having upper and lower walls and lateral walls defining means at fixed width to align documents of a first width fitting snugly within the lateral walls; at least one movable divider wall means extending through one of the upper or lower walls and into contact with the other, over a distance large in comparison to channel thickness and having a channel defining wall surface spaced from a lateral wall defining means in order to accept and align narrower documents of a second width fitting snugly therebetween, said divider wall having a tapering leading edge in the direction of document movement over the wall providing a decreasing space between the wall with which it is in contact away from the document insertion end of the channel, resilient means urging the movable divider wall into the wall with which it makes contact and yielding to documents passing over the leading tapered edge of the movable wall; and conveyor means to engage a document inserted into the channel and pull the document through the channel while maintaining position of the document relative to at least one lateral wall defining the channel.
Claim 3
Dependent Claim
47 words
The document handling device of claim 1 in which insert guide means is provided at least for the narrower documents to guide them into the space within the movable under walls at a point beyond the front edge of said movable wall without moving said movable wall.
Claim 4
Dependent Claim
103 words
The document handling device of claims 1 or 2 in which insert guide means is provided for documents of both the first and second widths but that the guide means for the documents of the second width is located above the guide means for the first width. Each of the guide means providing a tapering slot which tapers down to approximately the width of the space between the upper and lower walls of the conveyor channel and from a width somewhat wider than the guide channel to the approximate width of the space between the lateral walls defined in each channel prescribed width.
Claim 5
Dependent Claim
42 words
The document handling device of claim 1 in which the resilient means urging the movable divider wall into the wall with which it makes contact is integral with the movable divider wall and fixed to the housing structure to permit relative movement.
Claim 6
Dependent Claim
93 words
The document handling device of claim 4 in which the movable guide wall and resilient means is formed of an integral U-shaped piece and the bottom of the U-shaped member being bent along its length to provide the wall as a flange generally perpendicular to the base of the U and the structure being fixed to the wall at remote positions along their respective opposite arms causes the wall to yield under pressures applied to the wall and resiliently urges the movable wall into contact with the wall with which it makes contact.
Claim 7
Dependent Claim
37 words
The document handling device of claim 1 in which the movable wall extends through the wall opposite the one into which it is urged by resilient means and the resilient means are supported by said opposite wall.
