Copy machine with document dependent control.

摘要

A copy machine (1) having an eddy current proximity detector (15) positioned so relative movement is provided between the detector and a documentto be copied. The detec- tor is connected to control logic circuitry (40) 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 (4) is also connected to the control logic (40) for the copy machine so that closure of the document cover (3) is required for the production of a copy.
