PROBLEM TO BE SOLVED: To suppress the positional deviation of a granular material at the delivery between conveyance parts in a conveyance device including the plurality of conveyance parts.SOLUTION: A conveyance device includes a first conveyance part 31 and a second conveyance part 32 which respectively have a first circulation section 61 and a second circulation section 71 having a plurality of through holes 600, 700 arrayed in the lattice shape. The first circulation section includes a cylindrical surface-shaped delivery portion where a first suction region 611, a blow region 612 and a first cut-off region 613 are adjacent to each other in the order from the upstream side. The second circulation section includes a cylindrical surface-shaped reception portion where a second cut-off region 711 and a second suction region 712 continuous from a position P1 facing the blow region to the downstream side are adjacent to each other in the order from the upstream side and which faces the delivery portion. With this configuration, the granular material held by the one conveyance part is not affected by the air pressure in the other conveyance part at the front and rear spots of the delivery spot. Consequently, the positional deviation of the granular material can be suppressed.SELECTED DRAWING: Figure 6【課題】複数の搬送部を有する搬送装置において、搬送部間の受け渡し時に粒状物の位置ずれが生じるのを抑制する。【解決手段】この搬送装置は、格子状に配列された複数の貫通孔６００，７００を備える第１循環部６１および第２循環部７１をそれぞれ有する、第１搬送部３１および第２搬送部３２を備える。第１循環部は上流側から順に、第１吸着領域６１１、ブロー領域６１２および第１遮断領域６１３が隣り合う円筒面状の送出部を有する。第２循環部は上流側から順に、第２遮断領域７１１と、ブロー領域と対向する位置Ｐ１から下流側へ続く第２吸着領域７１２が隣り合い、送出部に対向する円筒面状の受取部を有する。これにより、受け渡し箇所の前後において、一方の搬送部に保持される粒状物に、他方の搬送部の内部の気圧の影響が及ばない。したがって、粒状物の位置ずれを抑制できる。【選択図】図６
