Description

The present disclosure relates to an image forming apparatus.

Conventionally, a post-processing device that performs post-processing on paper on which an image is formed by an image forming device main body has been used. Among the post-processing devices, for example, there is a device that outputs a product by dividing one sheet into a plurality of sheets and cutting them, but since there are a plurality of types of cutting, the number of items for cutting setting is large. Therefore, if the cutting setting is made for each print job for each item of the cutting setting, it takes time and effort to operate. Therefore, the post-processing apparatus saves the trouble of operating the cutting settings by registering a plurality of various cutting settings in advance as cutting profiles and reading the cutting profiles for each print job. Although the cutting profile itself can be registered independently of the print job, the user is finally made to select the cutting profile for each print job.

Therefore, if a large number of cutting profiles are registered, it is troublesome for the user to select the cutting profile corresponding to the print job from the cutting profiles in the registered list. Conventionally, a document that is the same as a print job from the print setting history and that selectively displays the latest document has been proposed (see, for example, Patent Document 1). Further, it has been proposed that an efficient cutting order is shown according to the aggregation setting (see, for example, Patent Document 2).

The details of the aftertreatment device 3 will be described later. The image forming apparatus main body 2 is an apparatus for forming a color image of an intermediate transfer method using an electrophotographic process technique. The image forming apparatus main body 2 is a vertical type in which photosensitive drums corresponding to the four colors of YMCK are arranged in series in the traveling direction of the intermediate transfer belt, that is, in the vertical direction, and the toner images of each color are sequentially transferred to the intermediate transfer belt in one procedure. The tandem method is adopted. That is, the image forming apparatus main body 2 primary transfers the Y (yellow), M (magenta), C (cyan), and K (black) color toner images formed on the photosensitive drum to the intermediate transfer belt, and performs intermediate transfer. An image is formed by superimposing toner images of four colors on a belt and then secondary transfer to paper P.

The image forming apparatus main body 2 includes an image reading unit 10, an operation display unit 20, an image processing unit 30, an image forming unit 40, a paper transport unit 50, a fixing unit 60, and a control unit 200. The image reading unit 10 includes an automatic document feeding device 11, a document image scanning device 12, and the like. The automatic document feeding device 11 is referred to as an ADF (Auto Document Feeder). The automatic document feeding device 11 conveys the document placed on the document tray by the conveying mechanism and sends it out to the document image scanning device 12. The automatic document feeding device 11 can continuously read images of a large number of documents placed on a document tray. When the automatic document feeding device 11 continuously reads images of a large number of documents, the automatic document feeding device 11 can read both sides of each document by the paper reversing mechanism. The document image scanning device 12 optically scans the document conveyed on the contact glass from the automatic document feeding device 11 or the document placed on the contact glass. The document image scanning device 12 reads the document image formed on the document by forming an image of the reflected light from the document by optical scanning on the light receiving surface of the CCD sensor. The image reading unit 10 generates input image data of the original image based on the scanning result by the original image scanning device 12. The input image data is supplied to the image processing unit 30, and the image processing unit 30 executes preset image processing.

The operation display unit 20 is realized by, for example, a liquid crystal display (LCD: Liquid Crystal Display) with a touch panel, and functions as a display unit 21 and an operation unit 22. The display unit 21 displays various operation screens, image states, operation statuses of each function, and the like according to the display control signals input from the control unit 200. The operation unit 22 includes various operation keys such as a numeric keypad and a start key. The operation unit 22 generates an operation signal by receiving various input operations by the user. The operation signal is output to the control unit 200.

The image processing unit 30 includes a circuit that performs digital image processing according to initial settings or user settings on the input image data. For example, under the control of the control unit 200, the image processing unit 30 performs gradation correction on the input image data based on the gradation correction table in which the gradation correction data is set. In addition to the gradation correction, the image processing unit 30 performs various correction processing such as color correction and shading correction, compression processing, and the like on the input image data. The image forming unit 40 performs various processes based on the input image data in which various digital image processes have been performed. The image forming unit 40 forms an image with the colored toners of the Y component, the M component, the C component, and the K component based on the input image data. The image forming unit 40 includes a photosensitive drum, a charging device, an exposure device, a developing device, and an intermediate transfer device. The surface of the photosensitive drum is uniformly charged by the corona discharge of the charging device. When the exposure apparatus irradiates the photosensitive drum with a laser beam corresponding to the image of each color component, an electrostatic latent image of each color component is formed on the surface of the photosensitive drum. When the developing device supplies the toner of each color component to the surface of the photosensitive drum, the electrostatic latent image is visualized and the toner image is formed. The toner image is transferred to the paper P by the intermediate transfer device.

The fixing unit 60 fixes the toner image on the paper P by heating and pressurizing the toner image transferred to the paper P. The paper transport unit 50 includes a paper feed unit 51, a paper discharge unit 52, a transport path unit 53, and the like.

E2, a paper discharge transport path E3, and a paper discharge transport path E4 are arranged. A purge tray 75 is arranged above the post-processing unit 71. A waste bin 76 is arranged below the post-processing unit 71. When the paper ejection sensor 73B1, the paper ejection sensor 73B2, the paper ejection sensor 73B3, and the paper ejection sensor 73B4 are collectively referred to, they are referred to as the paper ejection sensor 73B.

A long paper transport path D2 is arranged in the transport path D1. The long paper transport path D2 functions as a buffer when transporting long paper. A plurality of matching portions 77A are arranged on the long paper transport path D2. The matching unit 77A includes a pair of CD matching members (not shown) facing each other in a direction orthogonal to the transport direction of the paper P, a CD matching motor that reciprocates the CD matching members in a direction orthogonal to the transport direction of the paper P, and a CD matching member. It is equipped with a drive mechanism (all not shown). The matching portion 77A aligns the positions of the edges on both sides of the paper P by abutting the CD matching members against the edges on both sides of the paper P and reciprocating the CD matching members. The matching unit 77A is also arranged in the transport path D1.

The bending detection sensor 73C1 is composed of a pair of transmissive sensors arranged in the width direction of the paper P, and each transmissive sensor detects the passing time of two tips of the paper P. The bending detection sensor 73C2 is the same as the bending detection sensor 73C1. When the bending detection sensor 73C1 and the bending detection sensor 73C2 are collectively referred to, they are referred to as the bending detection sensor 73C. The steering roller 77B is a pair of steering rollers 77B arranged on the upstream side of the post-processing unit 71 along the direction orthogonal to the transport direction of the paper P. Specifically, the steering rollers 77B are arranged at positions facing each other in the width direction of the paper P, and based on the detection result of the bending detection sensor 73C1, the two tips of the paper P detected by the bending detection sensor 73C1. The bending of the paper P with respect to the transport direction of the paper P is adjusted by driving and controlling the respective rotation amounts in the same phase to cause a difference in the transport speed so as to eliminate the difference in the passing time. The steering roller 77B further adjusts the bending of the paper P with respect to the conveying direction of the paper P based on the detection result of the bending detection sensor 73C2.

The resist roller 77C aligns the tips of the paper P by hitting the tips of the paper P in a state where the rotation drive is stopped, and then forms a bend (loop) in the vertical direction on the paper P to form a bend (loop) of the paper P. The bending of the paper P with respect to the transport direction is corrected. The positioning sensor 73D is arranged on the upstream side of the post-processing unit 71 and detects the paper P transported to the post-processing unit 71. The post-processing unit 71 determines the position of the paper P when cutting the paper P based on the detection result of the positioning sensor 73D. Specifically, an image of the deliverable or the partition paper is printed on the paper P transported from the paper ejection portion 52 of the image forming apparatus main body 2 to the transport path D1. The post-processing unit 71 is arranged on the rear side of the image forming apparatus main body 2 that forms an image of the deliverable and the partition paper, cuts the paper P into a plurality of pieces, and forms the deliverable and the partition paper. That is, the control unit 300 causes the post-processing unit 71 to cut the deliverable formed on a part of the paper P and the partition paper formed on the other part of the paper P. The post-processing unit 71 includes at least one of a post-processing module 71A, a post-processing module 71B, a post-processing module 71C, and a post-processing module 71D. Each of the post-processing modules 71A to 71D is detachable from the post-processing device 3, and the arrangement order can be changed as appropriate. For example, it is possible to remove at least one of the post-processing modules 71A-71D from the post-processing device 3 depending on the deliverable.

The post-processing module 71A includes a slitter that cuts the paper P in the transport direction, that is, the sub-scanning direction. The post-processing module 71A cuts, for example, the top and bottom margins as the first margin of the paper P. The slitter of the post-processing module 71A functions as a top-bottom slitter when cutting the top-bottom margin. The post-processing module 71B may include, for example, a scoring portion for scoring the paper P cut by the post-processing module 71A. The post-processing module 71B may be provided with a perforation portion for forming a perforation on the paper P cut by the post-processing module 71A. However, the post-processing module 71B may be provided with only a guide plate along the transport path D1 when the paper P is not processed such as scoring or perforation. The post-processing module 71C includes a slitter that cuts the paper P in the transport direction. The position where the slitter of the post-processing module 71C is arranged is different from the position where the slitter of the post-processing module 71A is arranged. The post-processing module 71C cuts, for example, a margin between deliverables or a partition paper as a second margin of paper P. The slitter of the post-processing module 71C functions as a dove-cutting slitter when cutting a margin between deliverables or dividers. The post-processing module 71D includes a guillotine cutter that cuts the paper P cut by the post-processing module 71C in a direction orthogonal to the transport direction, that is, in the main scanning direction. The paper P cut in the main scanning direction by the post-processing module 71D is subsequently conveyed as deliverables, dividers or chips. Cutting the paper P in parallel with the transport direction is called FD (Feed Direction) cutting, and cutting the paper P in the direction orthogonal to the transport direction is called CD (Cross Direction) cutting. The FD cutting is performed by the post-processing modules 71A and 71C, and the CD cutting is performed by the post-processing module 71D.

The transport path switching unit 72 switches to any of the paper discharge transport paths E1 to E4 depending on the destination of the paper P that has passed through the post-processing unit 71. The paper discharge transport path E1 transports the deliverable or the partition paper to the card tray 74. The paper discharge transport path E2 transports the deliverable or partition paper to the purge tray 75. The paper discharge transport path E3 transports chips to the waste bin 76. The paper discharge transport path E4 transports the deliverable or the partition paper to another processing device connected to the rear stage side of the post-processing device 3. The jam detection sensor 73A is arranged between the post-processing module 71D and the transport path switching unit 72, and detects the deliverable or the partition paper output from the post-processing module 71D. If the jam detection sensor 73A does not detect the deliverable or the partition paper even after the lapse of the preset time, the control unit 300 determines that the jam has occurred in the transport path D1.

The card tray 74 may be a paper ejection destination of the paper ejection transport path E1 switched by the transport path switching unit 72, and may be formed in a size capable of accommodating deliverables and partition paper. The card tray 74 can be loaded with deliverables and dividers transported by the paper ejection transport path E1. The control unit 300 controls to transport the deliverable and the partition paper to the card tray 74 by the paper discharge transport path E1. A paper ejection sensor 73B1 is arranged in the paper ejection transport path E1. Therefore, the control unit 300 can detect whether or not the deliverable or the partition paper transported by the paper ejection transport path E1 is reliably ejected to the card tray 74 based on the detection result of the paper ejection sensor 73B1.

The purge tray 75 is a paper discharge destination of the paper discharge transport path E2 switched by the transport path switching unit 72, and in addition to the deliverable and the partition paper, the purge tray 75 also loads the paper cut to a size larger than the deliverable and the partition paper. It is possible. The control unit 300 controls to transport the deliverable and the partition paper to the purge tray 75 by the paper discharge transport path E2. A paper discharge sensor 73B2 is arranged on the paper discharge transport path E2. Therefore, the control unit 300 can detect whether or not the deliverable or partition paper transported by the paper discharge transport path E2 is reliably discharged to the purge tray 75 based on the detection result of the paper discharge sensor 73B2.

The waste bin 76 is a paper discharge destination of the paper discharge transport path E3 switched by the transport path switching unit 72. The waste bin 76 contains chips such as a first margin, a second margin, and a margin between deliverables cut by the post-processing unit 71. The control unit 300 controls to convey various chips cut by the post-processing unit 71 to the waste bin 76 by the paper discharge transport path E3. A paper ejection sensor 73B3 is arranged in the paper ejection transport path E3. Therefore, the control unit 300 can detect whether or not the various chips transported by the paper ejection transport path E3 are reliably ejected to the waste bin 76 based on the detection result of the paper ejection sensor 73B3. When the waste bin 76 is arranged directly under the post-processing unit 71, the cut chips are dropped directly onto the waste box 76, so that the paper discharge transport path E3 is not arranged and the paper discharge sensor 73B3 is unnecessary. is there.

When the processing device is connected to the rear stage side of the post-processing device 3, the paper discharge transport path E4 is a deliverable or a partition to the processing device which is the paper ejection destination of the paper discharge transport path E4 switched by the transport path switching unit 72.
