Conveyor device and image forming apparatus

摘要

A plurality of suction holes are formed in a conveyance belt of a conveyor device. A suction unit is arranged on one of surfaces of the conveyance belt. The suction unit includes a unit case in which cells adjacent in a paper conveyance direction are formed and defined by a partition wall extending in a width direction of the conveyance belt, a ceiling wall interposed between the unit case and the conveyance belt, and a fan provided in each of the adjacent cells. The ceiling wall includes a slit group which communicates the respective adjacent cells with the plurality of suction holes. The slit group includes a plurality of slits formed across the partition wall. The plurality of slits formed across the partition wall include slits in communication with one of the adjacent cells and slits in communication with the other of the adjacent cells.

主权项

1. A conveyor device which conveys a recording medium, comprising:
a conveyance belt in which a plurality of suction holes are formed and which is driven in a conveyance direction of the recording medium; and a suction unit arranged on one of surfaces of the conveyance belt and configured to suck the recording medium on the other surface of the conveyance belt through the plurality of suction holes, wherein the suction unit includes:
a unit case in which cells adjacent in the conveyance direction of the recording medium are formed and defined by a partition wall extending in a width direction of the conveyance belt;a ceiling wall interposed between the unit case and the conveyance belt; anda suction section provided in each of the adjacent cells and configured to generate negative pressure in an interior of the corresponding cell, wherein respective suction forces per unit area applied to the recording medium in any two adjacent cells, are different from each other; the ceiling wall includes a slit group which communicates the respective adjacent cells with the plurality of suction holes, the slit group includes a plurality of slits formed across the partition wall, and the plurality of slits include slits in communication with one of the adjacent cells and slits in communication with the other of the adjacent cells.
