Abstract
A copy machine achieves a reduction in power consumption when performing a saddle-stitching operation. An image forming unit forms visible images on recording sheets in accordance with image data stored in a memory device. A post-processing unit collects the recording media on an individual copy basis to prepare a bundle of the recording sheets, and performs a saddle-stitching process and a center-folding process on the bundle of the recording sheets. The post-processing unit ejects the processed recording sheets onto a predetermined eject tray. A system control part determines whether or not a total number of the recording sheets corresponding to the image data is within a limit number for the saddle-stitching process. When the total number of the recording sheets exceeds the limit number for the saddle-stitching process, the recording sheets are ejected onto the at least one eject tray other than a predetermined eject tray.
Description
- 1. Field of the Invention
- The present invention generally relates to image forming apparatuses and, more particularly, to an image forming apparatus such a printer having a saddle-stitching and center-folding function of printed sheets.
- 2. Description of the Related Art
- Image outputting apparatuses such as a copy machine or a printer have become multi-functioned, and many image-outputting apparatuses are equipped with a memory device that can store a large amount of image data. Additionally, with such a multi-functionalization of the image outputting apparatuses, a post-processing apparatus has been diversified in its function such as a stapling function to staple output print papers.
- As one of such techniques, Japanese Laid-Open Patent Application No. 11-151837 suggests a print apparatus having a stapling function, which performs a printing operation while canceling the stapling function if a number of print papers exceeds a number of sheets which can be stapled. Additionally, Japanese Laid-Open Patent Application No. 11-189365 suggests an image process post-processing apparatus, which determines whether or not a stapling can be applied, and prohibit a stapling operation if it is determined that a stapling is not applicable, and ejects print papers in a stapling part onto an eject tray. Further, Japanese Laid-Open Patent Application No. 9-183558 suggests a sheet post-processing apparatus having the same function as mentioned above.
- Furthermore, Japanese Laid-Open Patent Application No. 2000-118860 suggests a technique to perform a saddle stitch-process, which staples central portions of print papers in a paper feeding direction in addition to an end-stitching process, which staples an end portion of print papers. In such a saddle stitching process, print papers are temporarily conveyed to a stacking tray so as to align the print papers for stapling. Then, if a number of print papers is within a limit number for saddle stitching, the saddle stitching process is performed. On the other hand, if the number of print papers exceeds the limit number for saddle stitching, the print papers are ejected from the stacking tray to an outside tray without performing the saddle stitching process at that time.
- In a conventional image forming apparatus, which performs such a saddle-stitching operation, if a number of sheets of printed paper temporarily stacked on the stack tray exceeds a maximum saddle-stitching number, the printed papers stacked on the stack tray is ejected therefrom and, thereafter, subsequent printed papers are stacked on the stack tray. For this reason, it takes a time to determine whether or not the number of printed papers stacked on the stack tray exceeds the maximum saddle-stitching number in addition to a time to stack the printed papers on the stack tray. Thereby, a processing time of the saddle-stitching operation is long, which lowers a productivity of the image forming apparatus. Moreover, in order to temporarily stack the printed papers on the stack tray, when the saddle stitching operation is not performed, a motor, which is not required to operate when performing the saddle-stitching operation, is unnecessarily driven, which results in an unnecessary consumption of electric power. Furthermore, since the printed papers are not bound if the printed papers are ejected from the stack tray to the outside tray, the printed papers are offset from each other and it is difficult to achieve a sufficient alignment.
- It is a general object of the present invention to provide an improved and useful image forming apparatus in which the above-mentioned problems are eliminated.
- A more specific object of the present invention is to provide an image forming apparatus which achieves a reduction in power consumption when performing a saddle-stitching operation and improves a productivity.

The mainunit control unit 20 is provided with asystem control part 21, a picture-processingcontrol part 22, a memory device (memory means) 23, an image write-inunit control part 24, ascanner control part 25, anexternal interface 26, etc. - The system control
part 21 controls an operation of theentire copy machine 1 including thepost-processing unit 10, and performs a copy process and a post-processing control process mentioned later. Theexternal interface 26 is connected to an external apparatus such as a personal computer directly or through a network such as a local area network (LAN). Theexternal interface 26 operates under a control of thesystem control section 21 so as to send image data of an original document, which is read by thescanner 5, by exchanging commands with the external apparatus, and receive image data from the external apparatus and transfer the received image date to the imageprocessing control part 22. - The
scanner control part 25 controls the operations of thescanner 5 and theARDF 6 under the control of thesystem control part 21 so as to cause theARDF 6 to convey original document-and cause thescanner 5 to read images on the conveyed original document, and transfers image data of the original document sent from thescanner 5 to the imageprocessing control part 22. The image write-inunit control part 24 controls operations of the image formation part of themain unit 2 under the control of thesystem control part 21 so as to cause the image formation part to from an image on a print paper in accordance with the image data transferred from the imageprocessing control part 22. The imageprocessing control part 22 applies necessary processes to the document image data read by thescanner 5 and supplied by thescanner control part 25 or data sent from an external apparatus and supplied by theexternal interface 26, and store the data in thememory device 23. Additionally, the imageprocessing control part 22 transfers image data to be stored in thememory device 23 to the image write-inunit control part 24 or theexternal interface 26 under the control of thesystem control part 21. The system controlpart 21 controls each part of thecopy machine 1 so as to perform a fundamental process as a copy machine, and performs a post-processing control process mentioned later. - The
copy machine 1 determines whether or not a stapling operation can be applied in accordance with an amount of data stored in thememory device 23 when performing a saddle-stitching process using thestack tray 15 by thepost-processing unit 10. If thecopy machine 1 determines that the stapling operation cannot be applied, printed papers are ejected onto a tray other than the saddle-stitching eject tray 18. It should be noted that although a description will be given below of a case where the original document is read by thescanner 5 and an image formation is performed in accordance with image data of the original document read by thescanner 5 and thereafter post-processing is performed, the same process can be applied to a case of data from an external apparatus supplied through theexternal interface 26. Additionally, although the description given below is directed to a case where thesystem control part 21 controls a series of processes, other processing parts such as an additional processing part may perform such a series of processes. - In the
copy machine 1, original documents are set in theARDF 6, as shown in FIG. 3, and a desired operation mode is set. Then, after a start key is pressed, thesystem control part 21 determines whether or not the saddle-stitching mode using the stack tray is selected (step S101). If the saddle-stitching mode is selected, thesystem control part 21 starts to acquire image data to be printed out and accumulates the image data in the memory device 23 (step 102). The image data is sent from the personal computer (hereinafter, abbreviated as PC) through the communication means when data from the PC is to be printed. If the data read by the scanner is to be printed, the image data is sent from thescanner 5. For example, if the image data from the scanner is to be printed, thesystem control part 21 controls operations of theARDF 6 and thescanner 5 through thescanner control part 25 so as to cause theARDF 6 to feed the original documents to thescanner 5 on an individual sheet basis and cause thescanner 5 to read the original documents. Subsequently, the imageprocessing control part 22 applies necessary image processes to the image data acquired by thescanner 5 and causes thememory device 23 to store the image data, and checks whether or not the reading of all the original documents has been completed. If the image data is data from the PC, the imageprocessing control part 22 checks whether or not all the image data from the PC has been acquired (step S103). - After the reading of all the original documents has been completed in step S103, the systems control
part 21 applies a face-attachment process (step S104). Thereafter, thesystem control part 21 calculates a total number of sheets to print from an amount of image data accumulated in thememory device 23, and determines whether or not the total number of sheets to print are the designated paper size and can be stapled with the saddle-stitching (step S105). The face-attachment process is a process to change a memory assignment so that printed papers are arranged in an order of pages, that is, an order frompage 1 topage 12, when the printed papers are saddle-stitched and center-folded as shown in FIG. 4. In FIG. 4, page numbers are indicated simply as numbers 1-12. - If it is determined in step S105 that the total number of sheets to print is within the limit of saddle-stitching, the
system control part 21 starts the image forming process in accordance with the face-attached image data (step S106). Then, thesystem control part 21 performs the designated saddle-stitching staple process (step S107). Then, the printed papers are ejected on an individual sheet basis, and after the saddle-stitching and paper eject are completed to the end (step S108-Y), operation of the process is ended. - On the other hand, if it is determined in step S105 that the total number of sheets to print is beyond the limit of saddle-stitching, the
system control part 21 performs a notification display process to notify the user of the fact that the saddle-stitching staple process cannot be performed (step S109). Furthermore, thesystem control part 21 displays whether to divide the number of pages, which cannot be stapled, into a plurality of parts (step S110) or consolidate a number of pages (step S111), so as to let the user select one of them. When the user designates the face-attachment process of the plurality of parts and also designates a dividing process to divide the pages into a number of parts (step S110-Y), thesystem control part 21 checks whether or not a number of sheets in each of the parts (copies) divided in step S105 is within the limit of saddle-stitching. If the saddle-stitching can be applied, thesystem control part 21 performs the process of step S106 and the processes of the subsequent steps. On the other hand, if the saddle-stitching cannot be applied, the designation of the number of parts to divide is designated again in step S109 and step S110, and if it is determined in step S105 that the saddle-stitching is applicable, thesystem control part 21 performs the process of step S106 and the processes of subsequent steps. - If the face-attachment of the plurality of divided parts (copies) is not selected in step S110 (step S110-N), and if a consolidating process is selected, that is, if a process to incorporate images corresponding to a plurality of pages into one page is selected in step S111 (step S110-Y), the process returns to step S105. Then, the
system control part 21 checks whether or not a saddle-stitching staple can be applied with the selected number of collected pages. If the saddle-stitching is applicable, the process of step S106 and the processes of subsequent steps are selected. On the other hand, if the stitching cannot be applied, the number of pages to be consolidated is changed in step S111, and when the number of pages becomes within the limit of saddle-stitching, thesystem control part 21 performs the process of step S106 and the processes of subsequent steps. - When neither the face-attachment of a plurality of divided parts nor the consolidation is selected in steps S110 and Sill (including a case where no selection is made within a predetermined time period), the
system control part 21 checks whether or not there is a tray onto which the printed papers can be ejected other than the stack tray, that is, whether or not the proof tray or the shift tray is empty (step S112). When printed papers are placed on either of thetrays - On the other hand, when it is determined in step S112 that there is a tray onto which printed papers can be ejected other than the
stack tray 15, thesystem control part 21 checks whether or not the empty trays onto which the printed papers can be ejected is a sortable tray, that is, whether or not the tray is the shift tray 17 (step S114). If the empty tray is a sortable tray, thesystem control part 21 starts a paper eject operation to perform a sorting process for the printed papers (step S115). If the empty tray is not a sortable tray, that is, if the empty tray is aproof tray 16, thesystem control part 21 starts a paper eject operation without performing a sorting operation (step S116). That is, thesystem control part 21 reads the image data from thememory device 23, transfers the image data to the image write-inunit control part 24, and controls the image forming unit through the image write-inunit control part 24 to perform the image forming operation on a print paper. Moreover, thesystem control part 21 controls an operation of thepost-processing unit 10, and starts a paper eject operation with or without a sorting operation. - After the paper eject operation is started, the
system control part 21 checks whether or not thepaper eject tray system control part 21 checks whether or not an output of the last part of the image data has been completed (step S118). If the output of the last part is not completed, the process returns to step S117 where it is checked whether or not the usedeject trays discharge tray system control part 21 checks whether or not there is another empty tray (step S119). If there is no empty tray available, a notification indicating that there is no empty tray is displayed (step S120), and the paper eject operation is ended. - If there is an empty tray (
tray 16 or 17) onto which the printed papers can be ejected, thesystem control part 21 displays a notification indicating that the paper eject tray is full (step S121). Then, theempty tray eject tray - Moreover, if the saddle-stitching mode is not selected in step S101, it is checked-whether or not the end-stitching mode is selected (step S131). If the end-stitching mode is not selected, the
system control part 21 performs the process of the mode designated in step S132, and ends the whole process when the process of the mode designated in step S132 is completed (step S133-Y). - If the end-stitching mode is selected in step S131, the
system control part 21 acquires the image data in step S134. After the image data corresponding to predetermined number of lines is acquired (step S135-Y), the image forming operation is started (step S136). Then, the process of the end-stitching mode is performed (step S137) so as to end-stitch on an individual part basis, and the process is ended when the end-stitching of the last part is completed (step S138). - As mentioned above, the
copy machine 1 according to the present embodiment stores the input image data in thememory device 23 temporarily. Then, thecopy machine 1 performs a face-attachment process according to a number of pages on which the image formation of the image data is performed. The image forming unit of themain unit 2 of thecopy machine 1 perform an image formation on the print papers corresponding to a designated number of copies based on the image data on which the face-attachment process has been performed. The printed papers of the plurality of copies are arranged on thestack tray 15, and are bundled in each of the plurality of copies and sequentially stacked on an individual copy basis. The bundled and stacked printed papers are subjected to the saddle-stitching process by the saddle-stitching stapler 13, and, thereafter, subjected to the center-folding process and ejected onto the saddle-stitching eject tray 18. At this time, it is determined whether or not the total number of printed papers corresponding to the image data stored in thememory device 23 is within a number of papers which the saddle-stitching stapler 13 is capable of stapling. If it is determined that the number of papers exceeds the limit of number of papers which can be stapled, one of thetrays tray 18 is selected and the printed papers on which images are formed by the image forming unit are ejected onto the selected one of thetrays stack tray 15, which performs a stapling process, to the saddle-stitching eject tray 18, taking a time to receive next printed papers to receive a number of printed papers exceeding the limited number, performing an operation to eject the printed papers again from thestack tray 15 to the saddle-stitching eject tray 18, and repeating aforementioned process from one copy to a next copy until a desired number of copies are processed. Therefore, the productivity of thecopy machine 1 is improved, and printing papers can be tidily placed on thetray - Moreover, in the present embodiment, the
shift tray 17, which is capable of sorting printed papers, is provided as one of trays other than the saddle-stitching eject tray 18 onto which the printed papers can be ejected so as to eject the printed papers while sorting for each copy if the tray selected when stapling cannot be performed is theshift tray 17, which is capable of sorting. Therefore, the printed papers can be ejected on an individual copy basis and the productivity of the copy machine can be improved while improving convenience. - Furthermore, in the present embodiment, two
trays tray 18 as trays onto which the printed papers can be ejected. Thus, the tray selection process of selecting one of thetrays trays - It should be noted that, in the present embodiment, although not illustrated, the above-mentioned control unit is provided on the upper surface of the
scanner 5 at a front side of theARDF 6. - The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the present invention.
- The present application is based on Japanese priority applications No. 2003-105566 filed Apr. 9, 2003 and No. 2004-29559 filed Feb. 5, 2004, the entire contents of which are hereby incorporated by reference.
