Medium processing apparatus and image forming system incorporating same
A medium processing apparatus includes a liquid applier, a post-processing device, a liquid storage unit, a mover, and a liquid supplier. The liquid applier applies liquid to at least one medium. The post-processing device performs a given process on a bundle of media including the at least one medium on which the liquid is applied by the liquid applier. The liquid storage unit stores the liquid to be supplied to the liquid applier. The mover causes the liquid applier to move in a reciprocating direction orthogonal to the conveyance direction. The liquid supplier supplies the liquid from the liquid storage unit to the liquid applier and includes an extensible member having an elastic cylindrical part on at least a part of the liquid supplier. The extensible member extends in the reciprocating direction of the mover.
1 . A medium processing apparatus comprising:
a liquid applier to apply liquid to at least one medium;
a post-processing device to perform a given process on a bundle of media including the at least one medium on which the liquid is applied by the liquid applier;
a liquid storage unit to store the liquid to be supplied to the liquid applier;
a mover to cause the liquid applier to move in a first direction orthogonal to a conveyance direction of the at least one medium and a second direction opposite to the first direction; and
a liquid supplier to supply the liquid from the liquid storage unit to the liquid applier,
the liquid supplier including an extensible member having an elastic cylindrical part on at least a part of the liquid supplier,
the extensible member configured to extend and contract in the first direction and the second direction, and
the extensible member including an elastic coil tube wound in a spiral.
2 . The medium processing apparatus according to claim 1 ,
wherein the extensible member includes an elastic cylindrical tube.
3 . The medium processing apparatus according to claim 1 ,
wherein a shortest length of the extensible member in a reciprocating movement of the liquid applier is a length of the extensible member applied with a pulling force to be longer than a natural length of the extensible member.
4 . The medium processing apparatus according to claim 1 ,
wherein a longest length of the extensible member in a reciprocating movement of the liquid applier is a length two times or more of a shortest length of the extensible member, and
the shortest length of the extensible member in the reciprocating movement of the liquid applier is a length of the extensible member applied with a pulling force to be longer than a natural length of the extensible member.
5 . The medium processing apparatus according to claim 1 ,
wherein a standby position of the liquid applier is closer to a liquid replenishment unit than to a middle position in a depth direction of the medium processing apparatus.
6 . The medium processing apparatus according to claim 1 ,
wherein the post-processing device includes a crimper to bind the bundle of media by pressing and deforming the bundle of media.
7 . The medium processing apparatus according to claim 1 ,
wherein the post-processing device includes a stapler.
8 . An image forming system comprising:
an image forming apparatus to form an image on a medium; and
the medium processing apparatus according to claim 1 to perform the given process on a bundle of media including the medium on which the image is formed by the image forming apparatus.
9 . A medium processing apparatus comprising:
a liquid applier to apply liquid to at least one medium;
a post-processing device to perform a given process on a bundle of media including the at least one medium on which the liquid is applied by the liquid applier;
a liquid storage unit to store the liquid to be supplied to the liquid applier;
a mover to cause the liquid applier to move in a first direction orthogonal to a conveyance direction of the at least one medium and a second direction opposite to the first direction; and
a liquid supplier to supply the liquid from the liquid storage unit to the liquid applier,
wherein the liquid supplier includes:
a cylindrical tube; and
a winder to concentrically wind the cylindrical tube, and
the cylindrical tube is extendable in the first direction and the second direction.
10 . An image forming system comprising:
an image forming apparatus to form an image on a medium; and
the medium processing apparatus according to claim 9 to perform the given process on the bundle of media including the at least one medium on which the image is formed by the image forming apparatus.
