Details

Inventors: Melcher, Richard A.;
Assignee: Brandt, Inc. (Bensalem, PA)
Primary Examiner: Burr; Edgar S.
Assistant Examiner: Keating; Joseph R.
Attorney, Agent or Firm: Shenier & O'Connor

Apparatus for counting and endorsing documents in which a motor drives respective pairs of feed rollers to move documents along a feed path from an input location and along the feed path to an output location. Movement of an endorser adjacent to the feed path from an inoperative position to an operative position reduces the motor excitation to cause the rollers to move the documents along the path at a slower rate.

DETAILED DESCRIPTION One object of my invention is to provide a document-handling apparatus that is capable of endorsing documents.
Another object of my invention is to provide a document-handling apparatus that operates reliably in the endorser mode.
Still another object of my invention is to provide a document-handling apparatus that operates at maximum efficiency when the endorser is not in operation.
Another object of my invention is to provide a document-handling apparatus that distinguishes between singly fed and doubly fed documents of the same average optical density.
Still another object of my invention is to provide a document-handling apparatus that distinguishes between spurious optical-density peaks of singly fed documents and peaks characteristic of doubly fed documents.
A further object of my invention is to provide a document-handling apparatus that maximizes the use of sensor information in detecting misfeeds.
An additional object of my invention is to provide a document-handling apparatus that does not require frequent replacement of components such as light-emitting diodes and the like.
A still further object of my invention is to provide a document-handling apparatus that is operable over a wide range of ambient conditions.
Another object of my invention is to provide a document-handling apparatus that is insensitive to changes in transport speed.
An additional object of my invention is to provide a document-handling apparatus that is easy to service.
A further object of my invention is to provide a document-handling apparatus that is simple and inexpensive.
Other and further objects of my invention will be apparent from the following description.
In one aspect, my invention contemplates apparatus in which the speed at which sheets are advanced along a path is controlled in accordance with whether a printing member such as an endorser roller is disposed in an operative position adjacent to the path or an inoperative position relatively remote from the path.
More particularly, the apparatus is driven at a lower speed when the endorser member is engaged and at a higher speed when the endorser member is disengaged
