PROBLEM TO BE SOLVED: To achieve a continuous operation for electric inspection of products without requiring special facilities for stopping the products on a transport conveyor and without stopping the process. SOLUTION: The power supply apparatus comprises a power input section 1 for taking in power supply from a primary power cord 11, plug socket boxes 22 for receiving power that is supplied from the power supply input section 1, and a circulation section 3 for circulating the plug socket boxes 22. The power supply input section 1 has a rotary section 14 having a plurality of primary plug sockets. The circulation section has an upper-stage transport conveyor 31 for transporting the plug socket boxes 22, a moving up and down mechanism sections 32 that is provided at each of an upstream side 31a and a downstream side 31b of the upper-stage transport conveyor 31, and a transport mechanism section for transporting the plug socket boxes 22 from the downstream side 31b to the upstream side 31a. Then, when the plug socket boxes 22 make a tour by the circulation section 3, control is made so that the rotary section 14 is also rotated by one turn in the same direction. COPYRIGHT: (C)2003,JPO
