Abstract
In a working system for circuit boards such as, typically, as an electronic component mounting apparatus, an image pickup camera mainly for detecting the position of a reference mark on a circuit board or/and for detecting the misalignment of an electronic component from the axis a mounting head holding the electronic component is also utilized for detecting a peculiar portion formed on one of board lifting plates for lifting a circuit board to be clamped at a working position on a circuit board transfer conveyer. The peculiar portion comprises a plurality of grooves formed on one board lifting plate made of stainless steel for being detected as a plurality of dark regions appearing on the stainless steel board lifting plate. When the circuit board is transferred to the working position on the circuit board transfer conveyer, one of the dark regions to be detected is hidden by the circuit board from the image pickup camera, so that the presence of the circuit board on the board transfer device can be judged. Further, the detection/non-detection of the peculiar portion by the image pickup camera can also be utilized to control or decelerate the transfer speed of the circuit board on the circuit board transfer conveyer.
