ABSTRACT:
Method and apparatus for effecting operations, such as punching holes in sheets of material at precise locations thereon. Each sheet has a reference marking thereon and is placed on a receiver one by one and is held in fixed position on the receiver. A T.V. camera views each sheet to detect the reference marking thereon and a visual display of the marking is produced on a T.V. monitor. Also produced on the monitor is a cross-hair grating with a coincident shaded box. The cross-hair grating is first aligned with a marking reference on a master sheet to establish a fixed relation between the cross-hair and the marking reference on the master sheet and thereby between the cross-hair and the operating system, for example, the punches for punching holes in the sheets. The master sheet is removed and the sheets to be punched are placed one by one on the receiver which is moved to align the reference marking on each sheet, as viewed on the monitor with the cross-hair grating thereon.
