CONVEYING DEVICE

Abstract

A conveying device which is disposed so as to face an image forming unit that performs image formation on a medium and which conveys the medium while sucking the medium, the conveying device including: a conveying surface having a suction region that sucks the medium, wherein the suction region includes a first suction region including a region that faces an entirety of the image forming unit along a conveying direction of the medium, and a second suction region located on an upstream side of the first suction region in a conveying direction, the second suction region sucking the medium with a stronger sucking force than the first suction region.

Description

Claims

1. A conveying device which is disposed so as to face an image forming unit that performs image formation on a medium and which conveys the medium while sucking the medium, the conveying device comprising: a conveying surface having a suction region that sucks the medium, wherein the suction region includes a first suction region including a region that faces an entirety of the image forming unit along a conveying direction of the medium, and a second suction region located on an upstream side of the first suction region in a conveying direction, the second suction region sucking the medium with a stronger sucking force than the first suction region.

2. The conveying device according to claim 1, further comprising: a conveyor belt having a plurality of belt holes, the conveyor belt conveying the medium in the conveying surface, anda support member supporting the conveyor belt in a surface opposite to the conveying surface of the conveyor belt, anda suction fan that suctions air through the plurality of belt holes so as to form the suction region in the conveying surface,wherein the support member includes a plurality of recesses arranged in each of the conveying direction and a width direction of the medium that is orthogonal to the conveying direction, the plurality of recesses being communicable with the belt holes; a plurality of first suction holes connected to some recesses among the plurality of recesses, the plurality of first suction holes forming the first suction region by suctioning air from the recesses; and a plurality of second suction holes connected to other recesses among the plurality of recesses, and having a wider suction path than the plurality of first suction holes, the plurality of second suction holes forming the second suction region by suctioning air from the recesses.

3. The conveying device according to claim 2, wherein the plurality of first suction holes have a narrower suction path than the belt holes, and the plurality of second suction holes have a wider suction path than the belt holes.

4. The conveying device according to claim 1, wherein the second suction region is less than half a length of the first suction region in the conveying direction.
