Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a schematic configuration of an image forming apparatus according to an embodiment of the present invention.

In the present embodiment, as an image forming apparatus, a multifunction device having a plurality of functions such as a copy, a printer, and a facsimile will be described as an example. The image forming apparatus may be a single-function apparatus as well as a multifunction device.

In FIG. 1, the image forming apparatus includes a scanner unit 301, a document feeder (DF) 302, a printer unit 313 including a four-color color drum, a paper feed deck 314, and a finisher 315.

First, the reading operation performed mainly by the scanner unit 301 will be described.

When the original is set on the platen and the scanning operation is performed, the user sets the original on the platen 307 and closes the DF 302. When the open / close sensor detects that the DF 302 is closed, the reflective document size detection sensor (not shown) in the housing of the scanner unit 301 detects the set document size. When the document size is detected, light is emitted from the light source 310 to the document, and the reflected light is incident on the CCD 343 via the reflector 311 and the lens 312. The CCD343 converts the incident light into a digital signal and sends it to the controller (see FIG. 6). The controller performs desired image processing on the transmitted digital signal, converts it into a laser recording signal, and stores it in the memory as image data.

When the document is set on the DF 302 and the scanning operation is performed, the user places the document face-up on the tray of the document setting unit 303 of the DF 302. When the document is placed, the document presence detection sensor 304 detects the document. When the controller receives the detection result of the document from the document presence / absence detection sensor 304, the controller rotates the document feeding roller 305 and the transport belt 306 to transport the document to a predetermined position on the document table 307. When the document is conveyed to a predetermined position, the controller performs a scanning operation similar to the scanning operation on the platen described above, and stores the image data in a memory (not shown). Then, the document for which the scanning operation has been completed is ejected to the document ejection tray 309 via the transport roller 308.

When there are a plurality of documents set on the DF 302, the controller ejects the document for which the scanning operation has been completed, and at the same time, feeds the next document via the document paper feed roller 305, and the next document is fed. Perform a reading operation. In this way, the operation of reading a plurality of originals is performed.

Next, the printing operation performed by the printer unit 313 will be described.

The image data once stored in the memory in the controller is transferred to the printer unit 313, and is converted into the recording laser light for each color of Yellow, Magenta, Cyan, and Black by the laser recording unit. Then, the recording laser light is applied to the photoconductors 316 of each color to form an electrostatic latent image on the photoconductors 316. Then, toner development is performed by the toner supplied from the toner cartridge 317, and the visualized image is first transferred to the intermediate transfer belt 321. After that, the intermediate transfer belt 321 rotates in the clockwise direction, and when the recording paper fed from the paper cassette 318 or the paper feed deck 314 through the paper feed transfer path 319 reaches the secondary transfer position 320, the intermediate transfer is performed. The image is transferred from the belt 321 to the recording paper. Toner is fixed to the recording paper on which the image is transferred by pressurization and heat in the fixing device 322, and the recording paper is conveyed along the paper ejection transport path. Then, the recording paper is discharged to the paper ejection port 325 to the finisher.

In the case of double-sided printing, after passing through the fuser 322, the flapper 327 switches the transport path, and then the recording paper switches back and is fed downward, and the secondary transfer position 320 is again passed through the double-sided printing paper transport path 330. The double-sided printing operation is realized.

Subsequently, the operation performed by the finisher 315 will be described.

The finisher 315 adds post-processing to the chart paper according to the settings specified by the user. Specifically, it has functions such as staple (1 place / 2 place binding), punch (2 holes / 3 holes / 4 holes), and saddle stitching. The configuration and operation of the finisher 315 will be described with reference to FIGS. 2 to 5.

In FIG. 2, the finisher 315 includes a transport roller 31-39, tip detection sensors 50 and 53, a rear end detection sensor 48, a stapler 42, a veneer 43, a stopper 44, and folding rollers 45 and 46. It includes a bundle transfer roller pair 47.

The finisher 315 may be operated by a command from the controller of the image forming apparatus of FIG. 1, or may be operated by a unique controller.

The recording paper that has passed through the paper ejection port 325 on the image forming apparatus side is sorted according to the user's settings, for example, according to the functions of copy, printer, and fax. When used as a printer, various types such as black-and-white print / color print, paper size, 2UP / 4UP printing / N-UP printing, double-sided, staple, punch, saddle stitching, middle fold, interleaving paper, front cover, back cover, etc. It can be set.

The recording paper conveyed from the image forming apparatus is discharged to one of the loading trays 328 and 329 and the saddle stitching processing tray 331 according to the type of finishing processing set by the user. For example, if the finishing process is not performed, the chart paper is ejected to the loading tray 328. When the normal staple process is executed, the paper is discharged to the loading tray 329, and when the saddle stitching process or the center folding process described later is executed, the paper is discharged to the saddle stitch processing tray 331.

Further, the recording paper conveyed from the image forming apparatus is conveyed by the conveying rollers 31, 37, 38 until the rear end of the recording paper comes to the rear end detection sensor 48. Then, when the rear end of the recording paper is detected by the rear end detection sensor 48, the transport rollers 37 and 38 holding the recording paper are stopped (see FIG. 3A).

Next, the recording paper is switched back by the reverse rotation of the transfer rollers 37 and 38, and the recording paper is conveyed by the transfer roller 36 until the tip of the recording paper comes to the tip detection sensor 50. Then, when the tip of the recording paper is detected by the tip detection sensor 50, the transport roller 36 holding the recording paper decelerates, and the tip of the recording paper is abutted against the nip of the skew correction roller 51 (FIG. 3). See (b)).

Even after the tip of the recording paper hits the nip of the skew correction roller 51, the transport roller 36 continues to rotate for a while. Then, after the recording paper forms a loop in the loop space, the transfer roller 36 stops.

Next, the skew correction roller 51 starts rotating. When the chart paper is skewed, the skew correction roller 51 corrects the skew. Then, the recording paper whose skew is corrected is conveyed in the direction of the conveying roller 39. When the tip of the recording paper is detected by the tip detection sensor 53, the recording paper is conveyed by a predetermined amount from that point, and the tip of the recording paper is abutted against the stopper 44 (see FIG. 4A). At this time, as shown in FIG. 4A, the recording paper is positioned by the stopper 44 so that the binding position by the stapler 42 comes to the center of the recording paper. By repeating the above operation, a plurality of sheets of recording paper are sequentially conveyed inside the transfer path 41.

Then, when all the recording papers constituting the bookbinding are conveyed inside the transfer path 41, the recording papers are aligned in the width direction by a width direction matching plate (not shown), and the recording paper bundle is formed inside the transfer path 41. Form. At this time, the recording paper conveyed to the inside of the transfer path 41 is sequentially conveyed from the recording paper corresponding to the inside of the main text of the bookbinding, and is conveyed so that the recording paper corresponding to the cover of the bookbinding is the last.

Then, when the saddle stitching process is set, the stapler 42 performs the saddle stitching process on the stack of recording paper. When the stack of recording paper is stapled by the stapler 42, the stopper 44 supporting the bundle of recording paper moves to the downstream side in the transport direction. Along with this, the stack of recording paper moves downstream in the transport direction (see FIG. 4B).

The stopper 44 positions the stack of recording paper so that the central portion of the stack of recording paper comes to the position of the veneer 43. Then, the tip of the veneer 43 comes into contact with the portion where the crease of the recording paper bundle positioned by the stopper 44 is formed, and the recording paper bundle is pushed into the nip of the folding rollers 45 and 46 to make a crease in the recording paper bundle. Form. Then, the recording paper bundle in which the folds are formed by the folding rollers 45 and 46 is discharged to the saddle stitching tray 331 by the bundle transport roller pair 47 (see FIG. 5).

Then, when the "close" button 1101 is pressed on the screen shown in FIG. 11A, the CPU 402 displays the screen shown in FIG. 11B.

When the start key 506 is pressed while the screen shown in FIG. 11B is displayed, the CPU 402 performs a document reading operation by the scanner unit 301 and a printing operation by the printer unit 313 according to the settings stored in the DRAM 406. Start.

By performing the above operations, the user can obtain the bookbinding in which the saddle stitching process and the saddle stitching process have been performed.

However, due to the ability of the finisher 315 (the ability to bind the recording paper and the ability to fold the recording paper), there is an upper limit to the number of recording papers that can be processed at one time. For example, the folding rollers 45 and 46 can fold only 25 sheets of recording paper at a time. Therefore, in the present embodiment, when the number of recording sheets required for printing an image in the saddle stitching process exceeds 25, the CPU 402 interrupts the job process and displays the error pop-up shown in FIG. 12 on the display unit 505. indicate.

The "Cancel" button 1201 is a button for forcibly terminating the job. The “Paper discharge to processing tray” button 1202 is a button for executing the saddle stitching process and discharging the paper to the saddle stitching processing tray 331 without executing only the stitching process. The “Paper discharge to loading tray” button 1203 is a button for executing the bookbinding layout processing and discharging the paper to the loading tray 328 without executing the binding process or the folding process for each recording paper.

Further, even when the middle folding process is executed, the folding rollers 45 and 46 can fold only 25 sheets of recording paper at a time. Therefore, if the upper limit of the number of recording sheets that can be processed at one time is exceeded, Job processing is interrupted. When the center folding process is performed, the folded recording paper is conveyed by the bundle transfer roller pair 47 without being bound. Therefore, the recording paper during transportation may shift, which causes jam.
