Medium processing apparatus and image forming system incorporating same
A medium processing apparatus includes a conveyor, a liquid applier, and a crimper. The conveyor conveys a medium in a conveyance direction. The liquid applier applies liquid to a liquid application position on the medium conveyed by the conveyor. The crimper presses and deforms the liquid application position on a plurality of media including the medium to bind the plurality of media. The liquid applier includes a liquid application rotator configured to rotate, in contact with the medium conveyed by the conveyor, about a pivot extending in a main scanning direction orthogonal to the conveyance direction of the medium and to a thickness direction of the medium, to apply the liquid to the medium.
1. A medium processing apparatus comprising:
a conveyor configured to convey a medium in a conveyance direction;
a liquid applier configured to apply liquid to a liquid application position on the medium conveyed by the conveyor; and
a crimper configured to press and deform the liquid application position on a plurality of media including the medium to bind the plurality of media,
wherein the liquid applier includes a liquid application rotator configured to rotate, in contact with the medium conveyed by the conveyor, about a pivot extending in a main scanning direction orthogonal to the conveyance direction of the medium and to a thickness direction of the medium, to apply the liquid to the medium.
2. The medium processing apparatus according to claim 1 ,
wherein the liquid applier is positioned to face the liquid application position when the conveyor temporarily stops conveying the medium.
3. The medium processing apparatus according to claim 1 , further comprising a processor configured to execute a process to correct an inclination of the medium or a process to punch a hole penetrating the medium in the thickness direction of the medium, in parallel with a liquid application process performed by the liquid applier, when the conveyor temporarily stops conveying the medium.
4. The medium processing apparatus according to claim 1 ,
wherein the liquid applier is configured to move in the main scanning direction and stand by at a position where the liquid applier faces the liquid application position before the conveyor starts conveying the medium.
5. The medium processing apparatus according to claim 1 ,
wherein the liquid applier includes a plurality of liquid application units apart from each other in the main scanning direction and movable in the main scanning direction.
6. The medium processing apparatus according to claim 1 ,
wherein the liquid applier is configured to adjust an amount of the liquid to be applied to each of the plurality of media conveyed by the conveyor.
7. The medium processing apparatus according to claim 6 ,
wherein the liquid applier includes a liquid application member configured to contact the medium and separate from the medium, and
wherein the liquid applier is configured to change a pressing force of the liquid application member against the medium to adjust the amount of the liquid to be applied.
8. An image forming system comprising:
an image forming apparatus configured to form an image on a medium; and
the medium processing apparatus according to claim 1 .
