Sheet conveying device and sheet processing device provided with same, and method for conveying sheet and method for processing sheet using sheet conveying device

A sheet conveying device for continuously conveying a sheet so as to hand over the sheet to a device disposed on a downstream side, the sheet conveying device comprising:

• a plurality of suction members each having a suction surface capable of sucking the sheet;
• a holding mechanism configured to hold the plurality of suction members in a state where the suction surfaces are arranged in a spaced-apart manner from each other along a circumference of a circle about a first axis and the plurality of suction members is rotatable about the first axis;
• a drive device having:
• a rotary shaft being rotatable about a second axis which is parallel to the first axis;
• and
• a connecting mechanism configured to connect the rotary shaft and the plurality of suction members to each other such that power from the rotary shaft is transmittable to the plurality of suction members;
• and
• a support mechanism configured to support the holding mechanism and the drive device, wherein
• the connecting mechanism is connected to the plurality of suction members in a state where each of the suction members is movable in a radial direction of the circle about the first axis, and
• the support mechanism supports the holding mechanism and the drive device such that the first axis of the holding mechanism and the second axis of the drive device are relatively movable from each other in a direction orthogonal to the first axis.
