Abstract
A vacuum cup mechanism with automatic venting means. A carriage member oscillates between a stack of documents and the main document transport means. A vacuum device mounted on the carriage has a flexible cup at one end and is connected to a vacuum source at the other end. The vacuum device has a body with an internal hollow chamber which is in fluid communication with the flexible cup and the vacuum source. The body rotates about a pivot point to control the operation of a valve which vents the vacuum at the vacuum cup when the document is placed into the main document transport.
