である。(G) Effect of the Invention As described above, according to the present invention, when each printed circuit board is conveyed by the movement of the reciprocating body through the substrate feeding member, when any one of the feeding claws is overloaded, the biasing force is applied. When the detection device detects the movement of the holding member against the body,
Since the driving device for the reciprocating body is stopped, it is possible to reliably prevent the printed circuit board and the board feeding member including the feeding claws from being damaged. However, even if one of the feed claws is overloaded when the respective printed circuit boards are simultaneously conveyed, a single detection device can handle it, and the configuration is extremely simple.
