Abstract
An inspection system for inspecting discrete wiring patterns on a continuous substrate sheet of a flexible material by making the use of the substrate sheet as a feeding carrier. The system is capable of assuring accurate positioning of the wiring patterns (14) for reliable inspection even with the use of the flexible substrate sheet (10) as the sole feeding carrier. The inspection system includes an inspection zone (30) provided with camera (51, 54) for inspecting the individual wiring patterns (14) and detecting a position of said wiring pattern on the substrate sheet. A draw-in roller (31, 32) is provided to introduce the substrate into the inspection zone. Associated with the draw-in roller is a draw-out roller (32, 33) which draws out the substrate sheet from the inspection zone and is positioned to define the inspection zone between the draw-in roller and the draw-out roller as well as to give a tension to the substrate sheet for extending the substrate sheet straight through the inspection zone. A controller (60) is provided to control a position of the substrate sheet passing through the inspection zone based upon a position signal detected by the camera as indicative of th…
