DOCUMENT RESPONSE CONTROL COPYING MACHINE

摘要

A copy machine having an eddy current proximity detector positioned so relative movement is provided between the detector and a document to be copied. The detector is connected to control logic circuitry for the copy machine so that the copy machine is prevented from producing a copy when the detector detects metal carried by the document. A document cover position indicating device is also connected to the control logic for the copy machine so that closure of the document cover is required for the production of a copy.
