Accordingly, in a checking unit of the delivery cylinder 21 , the paper sheet W can be highly accurately checked while being stably transported.

Accordingly, portions of the paper sheet W are sequentially brought in contact with the guide surface 53 a of the guide plate 53 from the leading end to the trailing end.
  • the first communication hole 57 a passes a base end portion of the suction open groove 47 a (see suction end position (III) of the first communication hole 57 a in FIG. 6B ), the communication between the first communication hole 57 a and the suction open groove 47 a is blocked and the suction operation by the first communication hole 57 a is terminated.

  • the suction guide 40 is configured to continuously perform sucking even after passing the shift position S where the transporting route C 2 of the paper sheet W shifts from the arc-shaped transporting route portion C 2 b to the linear transporting route portion C 2 a, according to the preset length of the suction open groove 47 a from the front end portion to the base end portion thereof and the preset circumferential length of the suction guide 40 including the number of the communication holes 57 a to 57 g and the number of negative pressure boxes 54 a to 54 g.
  • the paper sheet W can be stably transported. Accordingly, there are no risk of the paper sheet W being damaged and rubbed and no risk of accurate checking by the checking camera 23 being hindered.
  • each suction duct 44 is biased to be pushed against the side surface of the corresponding ring-shaped end plate 51 in the suction cylinder 50 .
  • This configuration effectively absorbs an assembly error of the suction cylinder 50 , mechanical vibrations, and the like. Accordingly, the stable suction operation is achieved and the reliability is high.
  • the present invention has such an advantage that a portion of the paper sheet W having passed the shift position S is guided to an inner side than the linear travelling route portion C 1 a by the air blown from the second air blowing nozzle 26 and the contact of the paper sheet W to the guide plate 53 is thereby assisted.
