DISPOSITIF D'ACHEMINEMENT DE FEUILLE ET DISPOSITIF DE TRAITEMENT DE FEUILLE ÉQUIPÉ DUDIT DISPOSITIF D'ACHEMINEMENT, ET PROCÉDÉ D'ACHEMINEMENT DE FEUILLE ET PROCÉDÉ DE TRAITEMENT DE FEUILLE À L'AIDE D'UN DISPOSITIF D'ACHEMINEMENT DE FEUILLE
A sheet conveying device (10) includes: a holding mechanism (17) configured to hold suction members (11,12) in a state where suction surfaces are arranged in a spaced-apart manner from each other along a circumference of a circle about a first axis (J1) and the suction members (11, 12) are rotatable about the first axis (J1); and a driving device (14) including a rotary shaft (14b) which is rotatable about a second axis (J2) parallel to the first axis (J1) and a connecting mechanism configured to connect the rotary shaft (14b) and suction members (11,12) to each other; and a support mechanism configured to support the holding mechanism (17) and the drive device(14). The connecting mechanism is connected to the suction members (11, 12) in a state where the suction members (11, 12) are movable in a radial direction of the circle about the first axis (J1). The support mechanism supports the holding mechanism (17) and the drive device (14) such that the holding mechanism (17) and the drive device (14) are relatively movable from each other in a direction orthogonal to the first axis (J1).
