る。In the above electrode plate detecting device, when the bending of the connecting piece is within the allowable range, the ring illumination light is emitted, so that the video signal is output from the CCD camera, and this is output by the image processing unit. The processed angular position is detected, the detected angular position data is output to the turntable, the connecting piece is rotated to a predetermined angular position, and the upper lid is automatically punched. On the other hand, when the bending of the connecting piece exceeds the allowable range, the ring illumination light is not emitted and the connecting piece is not imaged by the CCD camera. Therefore, the video signal is not output from the CCD camera, and the image processing unit determines that the connecting piece is defective and outputs a defective message. In the above, since it is possible to immediately determine whether the bending of the connecting piece is good or not depending on whether or not the ring illumination light is irradiated, it is a great advantage that image processing for this is almost unnecessary.
