Abstract

A post-processing device is provided with a post-processing unit which performs post-processing of a recording medium on which recording is performed, a transport path through which the recording medium is transported, or a deformation suppressing unit which suppresses deformation of the recording medium on a mounting unit on which the recording medium is mounted, in which the deformation suppressing unit is controlled based on a predetermined parameter related to recording processing with respect to the recording medium.

First claim

What is claimed is:

1. A post-processing device comprising:
a post-processing unit which performs post-processing of a recording medium on which recording is performed by using water-based ink;
a mounting unit on which the recording medium to be subjected to post-processing in the post-processing unit is mounted;
a deformation suppressing unit which suppresses deformation of the recording medium caused by a predetermined parameter related to recording processing with respect to the recording medium, in the mounting unit, the predetermined parameter being physical property information of the recording medium, information on recording environment in which recording is performed on the recording medium, or a lapsed time after performing recording on the recording medium; and
a control unit which controls the deformation suppressing unit,
wherein the control unit receives the predetermined parameter in cooperation with a recording unit-control unit that controls the recording processing, and changes suppressing intensity of the deformation suppressing unit relative to the recording medium based on the predetermined parameter, and
wherein information related to recording data for performing recording on the recording medium is included in the predetermined parameter.

2. The post-processing device according to claim 1 ,
wherein the deformation suppressing unit suppresses deformation of the recording medium using wind pressure.

3. The post-processing device according to claim 2 ,
wherein the water-based ink contains water of 50 weight % or more, and includes a water soluble organic solvent, surfactant, and pigment.

4. The post-processing device according to claim 2 ,
wherein the deformation suppressing unit includes three air blowers which face a mounting face,
wherein the three air blowers are disposed in line in a direction orthogonal to a direction in which a medium to be subjected to post-processing in the post-processing unit is discharged to the mounting unit,
wherein one air blower among the three air blowers is disposed at a center of the mounting unit with respect to the orthogonal direction, and is disposed by being interposed between other air blowers with respect to the orthogonal direction, and
wherein the control unit controls the air blowers which are operated, according to a difference in moisture between the inside and outside of the recording medium, and the surface of the recording medium which faces the mounting unit.

5. The post-processing device according to claim 4 ,
wherein the control unit controls the air blower which is disposed at the center to blow air in a case in which the difference in moisture between the inside and outside is a predetermined value or more, and a case in which the surface of the recording medium with large moisture does not face the mounting unit,
wherein the control unit controls the other air blowers to blow air in a case in which the difference in moisture between the inside and outside is a predetermined value or more, and a case in which the surface of the recording medium with large moisture faces the mounting unit, and
wherein the control unit controls the air blowers so as not to blow air in a case in which the difference in moisture between the inside and outside is less than a predetermined value.

6. The post-processing device according to claim 1 , further comprising:
an intermediate processing unit which performs intermediate processing, and a finishing unit which performs a finishing treatment as the post-processing unit,
wherein the intermediate processing unit performs reversal processing or drying processing of the recording medium as the intermediate processing, and
wherein the finishing unit performs stapling, punching, or sorting as the finishing treatment with respect to the plurality of recording media on which the intermediate processing is completed.

7. The post-processing device according to claim 1 , wherein
the deformation suppressing unit suppresses deformation of a plurality of recording mediums that are being mounted on the mounting unit and include the recording medium, and the deformation suppressing unit is arranged so as to overlap the mounting unit as viewed in a direction in which the plurality of recording mediums are stacked each other on the mounting unit.

8. The post-processing device according to claim 1 , further comprises
a pair of rollers that discharges the recording medium on which the post-processing has been performed to the mounting unit.

9. The post-processing device according to claim 1 , wherein
the suppressing unit includes a humidification unit that humidifies the recording medium to suppress the deformation of the recording medium.

10. A recording apparatus comprising:
a recording head which performs recording by applying water-based ink to a recording medium;
a recording head-control unit that controls recording processing;
a post-processing unit which performs post-processing of the recording medium on which recording is performed;
a mounting unit on which the recording medium to be subjected to post-processing in the post-processing unit is mounted;
a deformation suppressing unit which suppresses deformation of the recording medium caused by a predetermined parameter related to the recording processing with respect to the recording medium, in the mounting unit, the predetermined parameter being physical property information of the recording medium, information on recording environment in which recording is performed on the recording medium, or a lapsed time after performing recording on the recording medium; and
a control unit which controls the deformation suppressing unit,
wherein the control unit receives the predetermined parameter in cooperation with the recording head-control unit, and changes suppressing intensity of the deformation suppressing unit relative to the recording medium based on the predetermined parameter, and
wherein information related to recording data for performing recording on the recording medium is included in the predetermined parameter.
