A plurality of clamping plates 303 are installed on the conveying belt 302 at equal intervals. An insertion space 304 is formed between adjacent two clamping plates 303. The PCB 4 conveyed out of the conveying unit 2 moves towards the collecting conveying unit 3 and then is inserted into the insertion space 304. With the rotation of the conveying belt 302, the PCB 4 is conveyed backward.
