Abstract
Abstract A document transport system embodying a main guideway for singly conveying documents to one of a plurality of gated intersecting auxiliary guideways is disclosed. The destination of the document is read from the document by a reader such as a magnetic reading head. This information is then synchronously transferred through a plurality of registers with the movement of the document along the main guideway. Positioned along the main guideway and anteriorly to each intersecting guideway is a document detector having the functions of transferring the information from the previous register to the present register and actuate the gate to the auxiliary guideway if there is a verification between the destination information in the register and the gate identification. Several documents having different destinations may be transported along the main guideway at any one time.

Claim 1
Independent Claim
287 words
In a high-speed document transport system for transporting documents to one of a plurality of auxiliary guideways, a document control system to select a predetermined auxiliary guideway, said document control system comprising: a document transport guideway extending from an inlet end to a termination end to singly and successively transport documents; a plurality of identifiable spaced-apart intersecting guideways intersecting said document transport guideway; deflection means positioned at each intersection to deflect a document from the document transport guideway to an intersecting guideway; 1 reading means posteriorly disposed from said inlet and operatively connected to said document transport guideway to dynamically read the encoded destination information on the documents passing thereby; detection means anteriorly positioned with respect to document travel to said deflecting means respectively, said detection means operatively connected to said transport guideway to detect a document passing thereby; a first register operably connected to said reading means and the first of said detection means to receive from the reading means to the encoded destination information; a plurality of second register means respectively electrically connected to a different one of said detection means and connected in electrical series with said first register means to receive the destination information from said first register means in response to said detection means; a verifier responsive to one of said detection means and electrically connected to said register means to activate said deflection means upon verification between the encoded destination information and said intersecting guideway means; and timing means electrically connected to said first and second register means, respectively, said timing means responsive to detection means associated with said register means to generate an electrical signal to clear said register means of said destination information a predetermined time after receipt thereof.
Claim 2
Dependent Claim
287 words
In a high-speed document transport system for transporting documents to one of a plurality of auxiliary guideways, a document control system to select a predetermined auxiliary guideway, said document control system comprising: a document transport guideway extending from an inlet end to a termination end to singly and successively transport documents; a plurality of identifiable spaced-apart intersecting guideways intersecting said document transport guideway; deflection means positioned at each intersection to deflect a document from the document transport guideway to an intersecting guideway; 1 reading means posteriorly disposed from said inlet and operatively connected to said document transport guideway to dynamically read the encoded destination information on the documents passing thereby; detection means anteriorly positioned with respect to document travel to said deflecting means respectively, said detection means operatively connected to said transport guideway to detect a document passing thereby; a first register operably connected to said reading means and the first of said detection means to receive from the reading means to the encoded destination information; a plurality of second register means respectively electrically connected to a different one of said detection means and connected in electrical series with said first register means to receive the destination information from said first register means in response to said detection means; a verifier responsive to one of said detection means and electrically connected to said register means to activate said deflection means upon verification between the encoded destination information and said intersecting guideway means; and timing means electrically connected to said first and second register means, respectively, said timing means responsive to detection means associated with said register means to generate an electrical signal to clear said register means of said destination information a predetermined time after receipt thereof.
Claim 3
Dependent Claim
35 words
In a document transport system according to claim 1 wherein said timing means is a multivibrator having a predetermined time equal to the normal time it takes a document to travel between adjacent detection means.
Claim 4
Dependent Claim
56 words
In a document transport system according to claim 1 wherein said timing means is a multivibrator having a predetermined time equal to the normal time it takes a document to travel from said detection means along said guideway to be positioned wholly within said intersecting guideway adjacent to said detection means in response to said verifier.
