Medium processing apparatus and image forming system incorporating same
A medium processing apparatus includes a conveyor, a receptacle, a liquid applier, and a crimper. The conveyor conveys a medium. The receptacle holds the medium conveyed by the conveyor. The liquid applier is disposed upstream from the receptacle in a conveyance direction of the medium to apply 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 held on the receptacle to bind the plurality of media.
1. A medium processing apparatus comprising:
a conveyor configured to convey a medium;
a receptacle configured to hold the medium conveyed by the conveyor;
a liquid applier disposed upstream from the receptacle in a conveyance direction of the medium 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 held on the receptacle to bind the plurality of media,
wherein the liquid applier is configured to move in a main scanning direction orthogonal to the conveyance direction of the medium and to a thickness direction of the medium and stand by at a position where the liquid applier faces the liquid application position before the conveyor starts conveying 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 a 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. 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 .
5. A medium processing apparatus comprising:
a conveyor configured to convey a medium;
a receptacle configured to hold the medium conveyed by the conveyor;
a liquid applier disposed upstream from the receptacle in a conveyance direction of the medium 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 held on the receptacle to bind the plurality of media,
wherein the liquid applier includes a plurality of liquid application units apart from each other in a main scanning direction orthogonal to the conveyance direction of the medium and to a thickness direction of the medium and movable in the main scanning direction.
6. A medium processing apparatus comprising:
a conveyor configured to convey a medium;
a receptacle configured to hold the medium conveyed by the conveyor;
a liquid applier disposed upstream from the receptacle in a conveyance direction of the medium 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 held on the receptacle to bind the plurality of media,
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,
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.
7. A medium processing apparatus comprising:
a conveyor configured to convey a medium;
a receptacle configured to hold the medium conveyed by the conveyor;
a liquid applier disposed upstream from the receptacle in a conveyance direction of the medium 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 held on the receptacle 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.
8. An image forming system comprising:
an image forming apparatus configured to form an image on a medium;
a medium processing apparatus configured to process the medium on which the image is formed by the image forming apparatus,
the medium processing apparatus including:
a conveyor configured to convey the medium;
a receptacle configured to hold the medium conveyed by the conveyor; and
a crimper configured to press and deform a liquid application position on a plurality of media including the medium held on the receptacle to bind the plurality of media; and
an intermediate apparatus interposed between a medium output portion of the image forming apparatus and the medium processing apparatus in a conveyance course of the medium,
the intermediate apparatus including a liquid applier disposed upstream from the receptacle in a conveyance direction of the medium to apply liquid to the liquid application position on the medium conveyed from the image forming apparatus,
wherein the liquid applier is configured to move in a main scanning direction orthogonal to the conveyance direction of the medium and to a thickness direction of the medium and stand by at a position where the liquid applier faces the liquid application position before the conveyor starts conveying the medium.
