Description

  The present invention relates to a sheet processing apparatus and an image forming apparatus including the sheet processing apparatus.

  Some image forming apparatuses having a copy or printer function are provided with a sheet processing apparatus for post-processing printing paper. A typical function of the sheet processing apparatus is a staple binding function. The staple binding function is a function of binding paper using a metal wire. Staple-bound printed materials are easy to handle for each copy, and are therefore widely used when handling multi-page output.

  Recently, environmental considerations have been made from the aspect of using metal needles, and binding methods that do not use needles have been devised. For example, a method has been devised in which a part of a set of printed paper to be bound is cut out in a lump so that the cut ends are woven and bound (see Patent Document 1).

  In addition, various binding methods that do not use metal needles have been put to practical use, such as a method of binding by attaching paper with glue, and a method of adhering and binding paper with pressure applied from above and below in the thickness direction of the paper. It is coming.

JP-A-8-300847

In the method in which pressure is applied in the thickness direction of the paper and the paper is tightly bound with the applied pressure, the binding force is weak.
The present invention has been made to solve the above problems.

  The present invention is a sheet processing apparatus for processing a sheet on which an image is recorded by a recording unit, the sheet processing apparatus including a first member and a second member, wherein the sheet on which an image is recorded by the recording unit is the first member. A binding means for performing a binding process in which the sheet is sandwiched between the second member and the second member to perform binding, and the binding means performs a first binding process on the sheet so that the longitudinal direction is at the end of the sheet. A first binding mark inclined with respect to the sheet is formed in a position near the corner of the sheet and intersecting the diagonal line of the sheet, and the second binding is performed on the sheet subjected to the first binding process. By performing the processing, a second binding trace whose longitudinal direction is parallel to the longitudinal direction of the first binding trace is formed at a position near the corner and intersecting the diagonal line. .

  According to the present invention, it is possible to increase the binding force in the method of pressing and binding paper.

<Description of system configuration>
[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of an image processing apparatus to which the sheet processing apparatus according to the present embodiment can be applied. In this example, a multi-function machine in which the image processing apparatus can be used as a copier is taken as an example.

In FIG. 1, a CPU 101 controls the entire apparatus as a system control unit. The ROM 102 is for storing a control program for the CPU 101. The SRAM 103 stores setting values registered by the operator, device management data, and various work buffers. It is a non-volatile SRAM that is backed up by a battery and does not lose its stored contents even when the device is turned off. The read image data is also stored here.
The DRAM 104 is for storing program control variables and the like. The operation unit 105 is an interface unit with a user that displays information in the device. The reading unit 106 is a device that reads image data and converts it into binary data, and uses this to read a document with an image transmission function. The recording unit 107 is an apparatus that outputs image data to recording paper. The image processing unit 108 performs encoding / decoding processing of image data handled by the image transmission function. Each control unit is connected via a data bus 110, and image data is transferred via the data bus 110.

  The recording unit 107 is connected to the sheet processing unit 109, and output paper printed by the recording unit 107 is sent to the sheet processing unit. The sheet processing unit 109 performs post-processing such as aligning input output sheets, switching output trays, and stapling. The sheet processing unit 109 includes two stapling units including a binding unit (stapling unit) that performs binding processing on a sheet without using a needle and a binding unit (stapling unit) that performs binding processing on a sheet using a needle.

Such a document image is read from the reading unit 106 and converted into binary data, and the read image data is temporarily stored in the SRAM 103. An example is a multi-function machine in which image data stored in the image processing unit 108 is converted, printed on paper by the recording unit 107, and post-sheet processing is performed by the sheet processing unit 109.
FIG. 2 is a diagram illustrating a configuration of the sheet processing unit 109 illustrated in FIG. This example shows an example of a sheet processing apparatus installed inside a housing of a multifunction peripheral.

  In FIG. 2, reference numeral 201 denotes a sheet processing unit, which is connected to the recording unit 107. Paper is sent from the recording unit 107 through the conveyance roller 204. Reference numeral 205 denotes a conveyance roller for reversing the paper during double-sided printing. When the paper is reversed, the transport roller 205 passes through here to enter the recording unit 107 again to print the back side. Also in this case, the output paper is sent to the sheet processing unit 201 through the conveyance roller 204.

The sheet processing unit 201 has a function of aligning and moving output sheets. Here, attention is paid to a staple binding function. Reference numeral 202 denotes a staple unit that performs staple use staples. The staple unit 202 performs a function process of binding paper using a metal needle such as a staple.
Reference numeral 203 denotes a staple unit that binds paper without using a needle. The staple unit 203 performs staple binding function processing without using a staple. As described above, there are a large number of staple binding methods that do not use a needle. Here, an example in which a paper that adheres and binds paper with pressure applied from above and below in the thickness direction of the paper is mounted.

  As an example, a sheet processing unit in which the staple processing unit 202 using the needle and the staple unit 203 not using the needle are provided in the sheet processing unit 201 will be described. However, the configuration may be such that only the staple non-use staple unit is provided.

FIG. 3 is a diagram for explaining the stapling operation of the stapling units 202 and 203 shown in FIG. This example shows the positional relationship between the stapling sections 202 and 203 that perform stapling and the sheet.
In FIG. 3, reference numeral 301 denotes an output sheet when binding, and the staple unit 202 moves to the staple 302 and binds the paper when the staple unit 202 actually binds the sheet from the standby position of the staple binding unit.
The staple unit 203 is configured to move to the staple position 303 and bind the paper when actually binding the paper from the standby position of the staple-free staple binding unit. In other words, the staple units 202 and 203 can be moved to the binding position and can be stapled by the control of the CPU 101 shown in FIG. 1 according to various binding methods.

  FIG. 4 is a cross-sectional view illustrating the binding process of the staple unit illustrated in FIG. Here, a description will be given of a method in which the sheets are brought into close contact with each other with pressure applied from above and below in the thickness direction of the sheets. Specifically, a state where the output sheet is set at a binding position and the staple unit 203 is moved to the stapling position 303 as shown in FIG. 3 corresponds to FIG.

In FIG. 4, 401 is an upper mold, and presses the sheet with pressure. The upper die 401 is provided with a plurality of convex blades, so that the upper die 401 cannot be removed immediately by pressurizing a plurality of points. Reference numeral 405 denotes a lower mold that presses the sheet with pressure. The lower mold 405 also has recesses 404 corresponding to the plurality of projections 402 of the upper mold 401 so as to receive the blade of the upper mold 401. As shown in FIG. 4B, the upper sheet 401 and the lower mold 405 press and hold the output sheet bundle 403 by pressing the sheet from above and below (by a pressing mechanism (not shown)) to bind the sheets. Is possible. The cross section of the output sheet bundle 403 after binding is as shown in FIG. When the bound sheet is viewed from above, the stapling portion 601 that has been stapled as shown in FIG. 6 can be silently viewed.
In the present embodiment, the black portion of the binding portion 601 in FIG. 6 is pressed to become a collapsed sheet portion. Since this method is performed by pressurizing, the number of sheets currently bound is limited in this method.
In addition, since the binding force is weak in one binding, the binding can be performed twice as described later.

The binding portion 701 can be moved from the position shown in FIG. 7A to the position shown in FIG. Further, the binding position and the number of times can be changed by adjusting the movement amount.
FIG. 8 shows a state in which the output paper bound twice in the binding portion is viewed from above, and a portion 801 bound in FIG. 7A further shows a portion 802 bound by the binding process. As the number of black portions in the pressurized portion shown in FIG. 8 increases, the amount of crimping increases and the binding force increases.
In addition, the staple-free staple binding is characterized by being able to remove the paper without tearing it by rubbing the pressed binding portion with a nail or the like.

  9 to 20 are diagrams illustrating an example of a UI screen displayed on the operation unit 105 illustrated in FIG. Hereinafter, an operation example during stapling processing will be described using each UI screen. The display on the operation unit 105 is realized by the CPU 101 displaying the operation unit 105 according to a program stored in the ROM 102. In the present embodiment, FIGS. 9 to 20 described later are provided as screens for setting additional conditions for adding concave and convex marks to be separated into sheets. Then, according to the mark addition conditions set using the UI screen, the CPU 101 controls the sheet processing unit 109 according to the procedure shown in the flowchart to be described later, and controls the binding process to place the uneven mark on the fed sheet.

FIG. 22 is a flowchart for explaining a control method of the sheet processing apparatus according to the present embodiment. This is an example of a copy job setting process for the image processing apparatus 100 shown in FIG. Each step is realized by the CPU 101 executing the program according to a program stored in the ROM 102. In the present embodiment, the additional conditions set by any one of the UI screens described above include position designation for adding the concave and convex marks, designation of the number of marks, and page designation for adding the marks. .
In addition, the page specification for adding a mark includes all page specification for adding a mark to all pages, page specification for adding a mark to the first page and the last page, and page specification for adding a mark to a specific page. It is configured to include.

  In step S <b> 2201, a setting for adding a 3D mark is received from the user via the 3D mark setting screen 1101 shown in FIG. 11 displayed on the operation unit 105. In S2202, if the CPU 101 determines that the key input from the user is the OK key 1106, the process proceeds to S2203, and if the input is other than that, the process proceeds to S2204.

  In S2203, since the number of marks and the mark position are not set, the CPU 101 generates stereoscopic mark addition page information with the default position and number. In step S <b> 2206, the CPU 101 designates the page number designation of the 3D mark added page information for all pages. In step S <b> 2215, the CPU 101 sets the job ID of the input copy job in the 3D mark added page information and records it in the 3D mark added page information list 2101 stored in the DRAM 104.

  On the other hand, if the CPU 101 determines in S2202 that an input other than the OK key has been received, the process advances to S2204. In S2204, when the CPU 101 determines that the user input has been received by pressing the detailed setting button 1104 for “detailed setting” on the UI screen shown in FIG. 11, the process proceeds to S2205, and other keys are received. If it is determined, the process proceeds to S2207.

On the other hand, when the CPU 101 determines in S2007 that the user input has received that the page selection button 1105 for “select page” has been pressed, the process proceeds to S2208, and it is determined that the key input is other than that. Ends this processing.

  In step S2208, the CPU 101 receives the page number and function designation set by the user using the page selection screen 1201 shown in FIG. 12 and the insertion sheet setting screen 1601 shown in FIG. Is generated.

Next, in S2209, if the CPU 101 determines that the user has accepted that the user has pressed the detailed setting button 1303 for “detailed setting” on the UI screen shown in FIG. 13, the process proceeds to S2210. Migrate to In step S2210, the CPU 101 receives the number of marks and the mark position set by the user on the detailed setting screen 1401 shown in FIG. 14 as stereoscopic mark addition page information.
In S2211, since the number of marks and the mark position are not set, the CPU 101 stores the default position and number in the 3D mark addition page information. In step S <b> 2212, the CPU 101 designates the page number designation of the 3D mark added page information as the set page, and stores the designated content in the DRAM 104.

In step S2213, the CPU 101 determines whether insertion of the next page is designated by the user. If the CPU 101 determines that the insertion of the next page is designated, the process proceeds to S2208. If the OK button is pressed, the process proceeds to S2203, and if the cancel button is pressed, the process proceeds to S2214.
In step S <b> 2214, the CPU 101 clears the three-dimensional mark addition page information list 2101 generated in the DRAM 104 and ends this processing.
