SUBSTRATE WORK MACHINE AND RECOGNITION METHOD

In a cut and clinch device, movable section 122 is slidable with respect to main body section 120. Also, a first insertion hole is formed in main body section 210, and a second insertion hole 136 is formed in curved section 133 of movable section 122 in a state overlapping the first insertion hole. A lead is cut by the movable section being slid with the lead inserted into the first insertion hole and the second insertion hole. In such a cut and clinch device, a pair of recognition marks 210 are provided on a bent section opposite each other centered around the second insertion hole. Thus, the recognition marks are imaged, and based on the image data, it is possible to appropriately recognize the opening position of the second insertion hole, to appropriately insert the lead into the second insertion hole, and to appropriately cut the lead.
