Abstract
Abstract Disclosed is a mechanism for feeding unit documents, such as sheets, envelopes, pages, cards, and the like to an apparatus for processing. A mechanism is provided for feeding the documents to and removing them from the operating apparatus at a relatively high rate of speed. During the time that an individual document is being operated upon it is conveyed by a mechanism associated with the operating apparatus. Examples of such operations would be printing addresses on an envelope, embossing credit cards, encoding magnetic tapes, and the like. Upon conclusion of the operation, the documents are removed quickly so that a second document may be supplied to the operating apparatus expeditiously.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
Unit document conveying apparatus for conveying documents to and from a work station, the combination comprising: A. a housing having: 1. a platform; 2. a first motor supported by said housing; 3. document drive means located at said platform; 4. means connected to said motor for selectively operating said drive means to convey a document across said platform upon actuation thereof; B. means for feeding documents individually onto said platform; and C. a work station operative to perform work on a document secured to said housing downstream from said platform and having: 1. a document receiving surface parallel to and in tandem with said platform; 2. a shaft having a drive roller thereon located adjacent said surface and having first and second drive members connected thereto, said first drive member being operative to drive said shaft faster than said second drive member, said second drive member having a one way clutch associated therewith that allows said faster rotating drive member to override said slower rotating drive member to rotatably drive said shaft, said drive roller engaging documents to transport the same across said document receiving surface at one speed when driven by said first drive member and at a slower speed when driven by said second drive member; 3. a second motor;

Claim 3
Dependent Claim
28 words
first drive connection for selectively connecting said first drive member to said first motor; and 5. second drive connection connecting said second drive member to said second motor.
Claim 4
Dependent Claim
28 words
first drive connection for selectively connecting said first drive member to said first motor; and 5. second drive connection connecting said second drive member to said second motor.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein said document drive means is a pusher mechanism and said operating means causes said pusher mechanism to reciprocate from a rest position, across said platform and back to said rest position.
Claim 6
Dependent Claim
24 words
The apparatus of claim 2 including means for enabling said feeding means in response to said pusher mechanism being returned to its rest position.
Claim 7
Dependent Claim
22 words
The apparatus of claim 2 including means for braking said operating means when said pusher mechanism is returned to its rest position.
Claim 8
Dependent Claim
21 words
The apparatus of claim 1 including means for sensing the presence of a document on the platform of said work station.
