1. Field of the Invention
The present invention relates to a sheet processing apparatus, a method for controlling a sheet processing apparatus, and a storage medium.
2. Description of the Related Art
Image forming apparatuses having a copy function and a printer function are provided with a function of inserting a sheet from a cassette tray different from a document main body. More specifically, there are a function of inserting a cover, a chapter sheet, and a slip sheet in a document main body, and a function of inserting a partition sheet, i.e., inserting a sheet from a different sheet feed unit between jobs and copies.
Further, for example, there are a function of printing a job while interrupting another job during outputting thereof, like interrupt copy, and a function of outputting a plurality of sheets with a patch pattern printed thereon and scanning the last sheet by a scanner to thereby improve correction accuracy for the purpose of stabilizing tint at the time of automatic gradation correction.
The above-described sheet insertion functions involve such a problem that a position of an inserted sheet cannot be specified unless a sheet of a different color or a different type is used as the inserted sheet. Further, when using the interrupt copy function, a user cannot easily determine from which sheet the user's output starts unless the user checks the printed contents, since the output sheets are inserted among a plurality of outputs.
Further, automatic gradation correction also requires a user to check printed contents to specify the last output among outputs to determine the last sheet allowed to be used in the automatic gradation correction.
As a measure for solving these problems, Japanese Patent Application Laid-Open No. 5-297693 discusses a technique of printing a mark so as to black an edge of a sheet, a date, a time, and a username to allow easy discrimination of the sheet.
Further, to provide another solution to these problems, Japanese Patent Application Laid-Open No. 2007-118374 discusses a technique of improving visibility by using a colored sheet.
On the other hand, some image forming apparatuses are equipped with a sheet processing apparatus configured to perform post processing on an output printed sheet. One representative function of this sheet processing apparatus is a stapling/binding function. The stapling/binding function is a function of binding sheets using a metallic wire. The stapled and bound print products can be easily handled as a single copy set, and therefore this function is widely used when treating an output constituted by a plurality of pages.
Further, in recent years, consideration has been given to an environment since the stapling/binding function uses a metallic staple, and there has been proposed a binding method that does not use a staple. For example, Japanese Patent Application Laid-Open No. 8-300847 discusses a method for collectively cutting out a part of a set of printed sheets to be bound as if gouging out it, and folding the cut tips in, thereby binding the sheets.
Other than that, various binding methods that do not use a metallic staple have been put into practical use. Examples thereof include a method for binding sheets by joining the sheets with glue, and a method for binding sheets by applying a pressure vertically in a thickness direction of the sheets to press the sheets into close contact with one another with the aid of the applied pressure.
Herein, the term “three-dimensional mark” will be used to refer to a function of partially changing the thickness of a sheet, and changing a texture of a sheet, like this stapling/binding method.
If a mark, a date, a time, and a username are printed at an edge of a sheet, like conventional techniques, a user cannot recognize the position thereof unless the user visually checks the printed surfaces by flipping through the outputs, whereby it is difficult to discriminate the insertion point among a large amount of outputs. Further, even with use of a colored sheet, a user should carefully search for the insertion point. Further, toner should be additionally consumed, leading to an increase in the cost.
Further, the sheet insertion function additionally inserts another sheet different from the document main body, and therefore outputs an extra sheet, leading to an increase in the cost.
According to an aspect of the present invention, a sheet processing apparatus includes a binding unit configured to perform a binding process for binding a plurality of sheets without use of a staple, a setting unit configured to set a sheet on which a concave and convex mark is to be formed by the binding unit, and a control unit configured to control the binding unit so as to form the concave and convex mark on the sheet set by the setting unit.
Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Next, an exemplary embodiment for carrying out the present invention will be described with reference to drawings.

A dynamic random access memory (DRAM) 104 is used to store program control variables and the like. An operation unit 105 is an interface unit to a user, which displays information in the apparatus. A reading unit 106 is a device that reads image data and converts it into binary data. The image processing apparatus reads a document for an image transmission function by using the reading unit 106. A recording unit 107 is a device that outputs image data onto a recording sheet. An image processing unit 108 codes and decodes image data processed by the image transmission function. The respective control units are connected via a data bus 110, and image data is transferred via the data bus 110.
Further, the recording unit 107 is connected to a sheet processing unit 109, and an output sheet printed by the recording unit 107 is conveyed to the sheet processing unit 109. The sheet processing unit 109 is a unit that performs post processing such as alignment of output sheets input from the recording unit 107, switching output trays, and stapling and binding the sheets. The sheet processing unit 109 includes two staple units, i.e., a binding unit (a staple unit) that binds sheets without use of a staple, and a binding unit (a staple unit) that binds sheets with use of a staple.
By way of example, the present exemplary embodiment is described based on such a multifunction peripheral that reads a document image and converts it into binary data by the reading unit 106, temporarily stores the read image data into the SRAM 103, converts the stored image data by the image processing unit 108, prints the image data on a sheet by the recording unit 107, and performs sheet post processing thereon by the sheet processing unit 109.

The sheet processing unit 201 has a function of aligning or moving output sheets, but the present exemplary embodiment is described focusing on the stapling/binding function. A staple unit 202 staples sheets with use of a staple. The staple unit 202 provides a function of binding sheets with use of a metallic wire such as a staple.
A staple unit 203 binds sheets without use of a staple (staple-less). The staple unit 203 provides a function of stapling and binding sheets without use of a staple. There are various methods for stapling and binding sheets without use of a staple as described above, and the present exemplary embodiment is described based on an example in which the sheet processing unit 201 is equipped with the staple unit 203 employing a method for binding sheets by applying a pressure vertically in a thickness direction of the sheets to press the sheets into close contact with one another with the aid of the applied pressure.
In this manner, in the present exemplary embodiment, the sheet processing unit 201 includes a sheet processing unit including both the staple unit 202 that uses a staple and the staple unit 203 that does not use a staple by way of example. However, the sheet processing unit 201 may be configured to include only the staple unit 203 that does not use a staple.
The staple unit 203 is configured to move from a standby position of the stapling/binding unit that does not use a staple to a stapling position 303, and bind the output sheets 301 at the position, when actually binding the output sheets 301. In other words, the staple units 202 and 203 is configured to be movable to a binding position to staple sheets at the position under control of the CPU 101 illustrated in

Specifying the number of printouts for automatic gradation correction is a function that allows the user to specify the number of printouts, because the accuracy of gradation correction increases by making a correction with use of a last printout among a plurality of continuously printed printouts when outputting an automatic gradation correction pattern but this has a demerit of wastefully using many sheets accordingly.

Further, when performing automatic gradation correction, it is also possible to easily specify a last sheet usable for this correction from stacked outputs. Further, it is possible to reduce the user cost by preventing unnecessary use of extra sheets and refraining from consuming consumable supplies such as toner and staples.
