Abstract: PROBLEM TO BE SOLVED: To enable a worker to efficiently supply part items to a work base in accordance with a work sequence without walking around by providing a stopping means for temporarily stopping a circular carrying means so as to stop part items fed by the circular carrying means before the work base. SOLUTION: If a worker (x) inserts his hand in the direction of a part box 10 after one part box 10 is stopped before a work base 2, since a received light quantity is reduced, an OFF signal is outputted from a sensor 3. If the worker pulls out his inserted hand subsequently, a received light quantity reaches its maximum (no blocking occurs), an ON signal is outputted from the sensor 3. Then, by operating a rounder driving device 20 by a certain amount with switching from the OFF to ON signal, a next part box 10 is brought before the work base 2. Thus, this rounder driving device 20 functions as a stopping means.
