Abstract

A post-processing device, includes a tray that accepts a carried sheet and places thereon; a post-processing unit that performs a post-processing to the sheet placed on the tray; and a controller that controls an operation of the post-processing unit. The controller that: obtains both of: a first sheet type specified by a user; and a second sheet type detected by a media detector that is installed on a sheet carrying path; and controls the operation of the post-processing unit based on the second sheet type when the first sheet type and the second sheet type are different.

Claims (103)

1. A post-processing device, comprising:

a tray that accepts a carried sheet and places thereon;

a post-processing unit that performs a post-processing to the sheet placed on the tray; and

a controller that controls an operation of the post-processing unit,

wherein the controller:

obtains both of:

a first sheet type specified by a user; and

a second sheet type detected by a media detector that is installed on a sheet carrying path; and

controls the operation of the post-processing unit based on the second sheet type when the first sheet type and the second sheet type are different.

2. A post-processing device, comprising:

a tray that accepts a carried sheet and places thereon;

a post-processing unit that performs a post-processing to the sheet placed on the tray; and

a controller that controls an operation of the post-processing unit,

wherein the controller:

obtains both of:

a first sheet type specified by a user; and

a second sheet type detected by a media detector that is installed on a sheet carrying path; and

controls the operation of the post-processing unit based on the second sheet type when the second sheet type is detected more in detail than the first sheet type.

3. The post-processing device according to claim 1 , wherein:

the post-processing unit comprises an aligning unit that aligns the sheet placed on the tray, and

the controller controls an operation of the aligning unit based on the second sheet type.

4. The post-processing device according to claim 3 , wherein

the aligning unit comprises a first aligning member that aligns the sheet placed on the tray in a carrying direction, and

the controller controls an operation of the first aligning member based on second sheet type.

5. The post-processing device according to claim 4 , wherein

the first aligning member:

is enabled to be lifted up and down above the tray;

is moved downward at a timing that the sheet is ejected between the tray and the first aligning member; and

holds an upper surface of the sheet and places on a top surface of the tray, and

the controller adjusts downward quantity of the first aligning member based on the second sheet type.

6. The post-processing device according to claim 5 , wherein

when the second sheet type is a thick paper, the controller reduces the downward quantity of the first aligning member compared to a thin paper.

7. The post-processing device according to claim 5 , wherein

the controller further adjusts the downward quantity of the first aligning member according to the number of the sheet placed on the tray.

8. The post-processing device according to claim 4 , wherein

the tray comprises a stopper that restricts movement of the sheet in the carrying direction,

the first aligning member comprises a rotation member that:

gets in contact with the sheet placed on the top surface of the tray; and

rotates to enable the sheet to but against the stopper and to be aligned, and

the controller adjusts the number of rotations of the rotation member based on the second sheet type.

9. The post-processing device according to claim 8 , wherein

the controller adjusts the number of rotations of the rotation member according to the number of the sheet placed on the tray.

10. The post-processing device according to claim 9 , wherein

in order to increase the number of rotations of the rotation member to a larger number of times than a predetermined number of times, the controller performs a control to expand a carrying interval of the sheets from an initial interval.

11. The post-processing device according to claim 3 , wherein

the aligning unit comprises a second aligning member that aligns the sheet placed on the tray in a direction orthogonal to the carrying direction, and

the controller controls an operation of the second aligning member based on second sheet type.

12. The post-processing device according to claim 11 , wherein

the controller adjusts a timing to start the operation of the second aligning member based on the second sheet type.

13. The post-processing device according to claim 11 , wherein

the controller adjusts the number of operations of the second aligning member based on the second sheet type.

14. The post-processing device according to claim 13 , wherein

in order to increase the number of operations of the second aligning member to a larger number of times than a predetermined number of times, the controller performs a control to expand the carrying interval of the sheets than the initial interval.

15. The post-processing device according to claim 3 , wherein:

the post-processing unit further comprises a stapler that staples a predetermined number of sheets after the predetermined number of sheets are placed on the tray and are aligned by the aligning unit, and

the controller controls the operation of the stapler based on the second sheet type.

16. The post-processing device according to claim 15 , wherein

the controller adjusts a driving voltage to drive the stapler based on the second sheet type.

17. The post-processing device according to claim 3 , wherein

the controller:

obtains density of an image formed on the sheet ejected on the upper surface side of the tray; and

controls the operation of the aligning unit based on the second sheet type and the density of the image.

18. The post-processing device according to claim 3 , wherein

the controller:

obtains environmental information that includes at least one of temperature and humidity; and

controls the operation of the aligning unit based on the second sheet type and the environmental information.

19. An image forming system, comprising:

a post-processing device according to claim 1 ; and

an image forming device that:

forms an image on a sheet; and

supplies the sheet on which the image is formed to the post-processing device.

20. A controlling method applied in a post-processing device to control an operation of a post-processing unit, wherein

the post-processing device comprises:

a tray that accepts a carried sheet and places thereon; and

the post-processing unit that performs a post-processing to the sheet placed on the tray, and

the controlling method comprises:

obtaining both of:

a first sheet type specified by a user; and

a second sheet type detected by a media detector that is installed on a sheet carrying path; and

controlling the operation of the post-processing unit based on the second sheet type when the first sheet type and the second sheet type are different.

21. A controlling method applied in a post-processing device to control an operation of a post-processing unit, wherein

the post-processing device comprises:

a tray that accepts a carried sheet and places thereon; and

the post-processing unit that performs a post-processing to the sheet placed on the tray, and

the controlling method comprises:

obtaining both of:

a first sheet type specified by a user; and

a second sheet type detected by a media detector that is installed on a sheet carrying path; and

controlling the operation of the post-processing unit based on the second sheet type when the second sheet type is detected more in detail than the first sheet type.

22. A non-transitory recording medium storing a computer readable program to be executed by a hardware processor in a post-processing device that comprises:

a tray that accepts a carried sheet and places thereon; and

the post-processing unit that performs a post-processing to the sheet placed on the tray, wherein the computer readable program causes the hardware processor executing the computer readable program to:

obtain both of:

a first sheet type specified by a user; and

a second sheet type detected by a media detector that is installed on a sheet carrying path; and

control the operation of the post-processing unit based on the second sheet type when the first sheet type and the second sheet type are different.
