Abstract
Before chuck 20 is opened, coil spring 22 is compressed, and coil spring 22 applies downward force to holding nails 24. Accordingly, when the chuck 20 is opened, resultant force that opens the chuck 20 and the restoring force of the coil spring 22 causes the holding nails 24 to automatically move in oblique downward directions. As a result, the holding nails 24 move to positions that are laterally close to the holding target workpiece 26a. At this time, when other workpieces 26b and 26c neighbor the holding target workpiece 26a, the holding nails 24 can move the neighboring workpieces 26b and 26c from the workpiece 26a so as to flick away the neighboring workpieces 26b and 26c.
