## Background
TECHNICAL FIELD
This application is based on Japanese Patent Application No. 2005-203284 filed on Jul. 12, 2005, in Japanese Patent Office, the entire content of which is hereby incorporated by reference.
BACKGROUND
The invention relates to an image forming apparatus.
Conventionally, an image forming apparatus such as a copier which image-forms on the recording sheet based on the image data is carried out. Further, as the image forming apparatus, an apparatus having a group-dividing function is investigated.
Referring to FIG. 12, the group-dividing function will be described. In FIG. 12, the recording sheets a31-a36 which is image-formed by the group-dividing function are shown.
The chapter is a collection formed of one or a plurality of image data. It is defined that the group dividing function is a function that, when the image data is double side image formed in order on the recording sheet, the image data of the first page of the chapter is image formed. on the surface. Further, when the last page of the chapter is image formed on the surface of the recording sheet, the white image data (NULL data) is added as the next image data, and on its rear surface, the white images data is image formed (the image data is not image formed).
For example, as shown in FIG. 12, the case where the image data A1-A3 are the first chapter, the image data A4-A8 are second chapter, the image data A9, A10 are the third chapter, and the image data A1-A10 are chapter-divided in order on the recording sheets a31-a36 and image formed, will be described.
In the first chapter, in the recording sheet a31, the image data Al is image formed on the surface b31, and the image data A2 is image formed on the rear surface c31. In the recording sheet a32, the image data A3 is image formed on the surface b32, and because the image data A4 is on the top page of the second chapter, the image data is not image formed on the rear surface c32.
In the same manner, in the second chapter, in the recording sheets a33-a35, the image data A4-A8 are image formed in order on the surface b33, the rear surface c34-surface b35, and on the rear surface c35, the image data is not image formed. In the same manner, in the third chapter, in the recording sheet a36, the image data A9, A10 are image formed in order on the surface b36, the rear surface c36.
Further, in the image forming apparatus having the group-dividing function, an apparatus having a function by which, together with the image data, the chapter number and the chapter page number are image formed, is considered (for example, Japanese Unexamined Patent Publication No. 2001-274977).
Referring to FIG. 13, in the image forming apparatus, the conventional third image forming processing by which the chapter number and the chapter page number are image-formed, will be described. In FIG. 13, a flow of the third image forming process is shown. The chapter number is a number by which each chapter is identified. The chapter page number is a page number for each chapter, and it is distinguished from the all-page number as the page number of the whole.
In the image forming apparatus, initially, it is inputted through an operation section from the user. The image formation position information of the chapter number and the chapter page number is received, and based on the position information, the image formation position of the chapter number and the chapter page number is set (step S51). Then, the letter size information of the chapter number and the chapter page number inputted through the operation section from the user, is received, and based on the letter size information, the letter size of the chapter number and the chapter page number is set.(step S52).
Then, the chapter diving designation page number information which is inputted through the operation section by the user, and is the top page of each chapter is received, and based on the page number information, the chapter dividing designation page number is set (step S53). Then, it is discriminated whether each kind of setting by the operation inputs are completed (step S54). When each kind of setting is not completed (step S54; NO), the sequence advances to step S51. When each kind of setting is completed (step S54; YES), the whole page number counter and the chapter page number counter are set to 0 (step S55). Then, the chapter number counter is set to 0 (step S56).
Then, the total page number counter is incremented (step S57). Then, it is discriminated whether the total page number of the total page number counter is the chapter dividing designation page number (step S58). When it is the chapter designation number (step S58; YES), the chapter page number counter is set in such a manner that the chapter page number=1 (step S59).
Then, the chapter number counter is incremented by 1 and set (step S60). Then, in the image data which is next image formed, in the position and the letter size set in steps S51, and S52, the chapter number and the chapter page number of the chapter number counter and the chapter page number counter are compounded as the image, and the composite image for the 1 page is image formed on the next surface of the recording sheet (step S61). The next surface of the recording sheet is, in the chapter page designation page, the surface of the next recording sheet, and in the other cases, the next surface or the rear surface of the image formed surface.
When it is not the chapter dividing designation page number (step S58; NO), the chapter page number counter is incremented by 1 and set (step S62) and the sequence advances to step S61.
Then, by step S61, it is judged whether the total pages are image formed (step S63), and when the all pages are not images formed (step S63; NO), the sequence advances to step S57. When all pages are image formed (step S63; YES), the third image formation processing is completed.
Referring to FIG. 14, an example of the image formation of the chapter number and the chapter page number by the third image formation processing will be described bellow. In FIG. 14, the recording sheets a41-a46 on which, together with the image data, the chapter number and the chapter page number are image formed will be shown.
The chapter-dividing in FIG. 14 is defined as the same as the example in FIG. 12. In the first chapter, in the recording sheet a41, on the surface b41, the image data A1, the chapter number and the chapter page number f1 are image formed, and on the rear surface c41, the image data A2, the chapter number and the chapter page number f2 are image formed.
The chapter number and the chapter page number are expressed in the form of “the chapter number—the chapter page number”. In the recording sheet a42, on the surface b42, the image data A3, the chapter number, and the chapter page number f3 are image formed, and on the rear surface c42, the image data, the chapter number and the chapter page number are not image formed.
In the same manner, in the second chapter, in the recording sheets a43-a45, on the surface b43, the rear surface c43—the surface b45, the image data A4-A8, the chapter number and the chapter page numbers f4-f8 are image formed in order, and on the rear surface c45, the image data, the chapter number and the chapter page number are not image formed. In the same manner, in the third chapter, in the recording sheet a46, on the surface b46, the rear surface c46, the image data A9, A9,A10, the chapter number and the chapter page numbers f9 and f10 are image formed in order.
However, in the image forming apparatus having the conventional group-dividing function, together with the image data, the text string except of the chapter number and the chapter page number can not be image formed.

In FIG. 7(b), a chapter title information input image plane 250 is shown. In FIG. 7(c), a chapter-dividing designation page number input image plane 230a is shown.
When the image data is image-formed on the recording sheet by the group-dividing function, the first image forming processing all-page-image forms the chapter title information of each chapter together with the image data. It is a processing by which it is selected that only the top page is image formed or it is not image formed, and image formed. For example, through the operation display section 30, it is made a trigger that the chapter-diving mode translation is inputted, and by the cooperation of the first image forming program which is read-out from the program memory 120 and developed in the system memory 130, and the image control section 110, the first image forming processing is conducted.
For example, when the main operation image plane 210 shown in FIG. 6(a) is displayed on the LCD 31, the applied function key 211 is touch-inputted by the user, the applied function operation image plane 220 shown in FIG. 6(b) is displayed on the LCD 31, and the chapter-dividing key 221 is touch-inputted by the user, the chapter-dividing mode is started, and the first image forming processing is conducted.
Initially, the image forming position information of the chapter title information on the recording sheet which is inputted by the user through the operation display section 30, is received, and based on the position information, the image forming position of the chapter title information is set (step S11). Then, the letter size information of the chapter title information which is inputted by the user through the operation display section 30, is received, and based on the letter size information, the letter size of the chapter title information is set (step S12).
Then, based on the chapter-dividing page number information which is the page number of top of inputted each chapter, the chapter title information of each chapter, and the kind of image formation, the chapter-dividing page number, the chapter title information, and the kind of the image formation, are set (step S13). The kind of the image formation is defined to be 3 kinds in which the chapter title is all-page image formed, the chapter title is image formed only on the chapter top page of each chapter, and the chapter title is not image formed.
In step S13, for example, as shown in FIG. 3, the chapter-dividing designation number information inputted by the user through the operation display section 30 and the chapter title information of each chapter and the kind of the image formation are received, and each information is set.
Specifically, the chapter-dividing designation page number input image plane 230 is displayed on LCD 31, based on the touch selection input of the chapter setting key 231 and the input of the numeral key as the hard key, the chapter-dividing page number is set. In this stage, because the setting relating to the chapter-dividing is not completed, the chapter title setting display section 232 is normally displayed. When OK key 233 is pressed in the chapter-dividing designation page number input image plane 230, the chapter title information list display image plane 240 is displayed on LCD 31, and based on the touch selection input of the chapter title information selection section 242, scroll-freely by the touch input of the scroll key 241, the chapter is selected in which the chapter title is newly inputted or edited.
Then, the chapter title information input image plane 250 shown in FIG. 7(b) is displayed on LCD 31, and the chapter title information is touch inputted by the letter input key 252, and the chapter title information is displayed on the chapter title information display section 251. Further, corresponding to respective cases of all-page image formation of the chapter title information of each chapter, image formation of only the chapter top page, or the image formation is not conducted, by the touch input of the chapter title setting section 253. (all-page) ON/(all-page) OFF/(only) the chapter top page, are switchingly inputted. When OK key 254 is pressed on the chapter title information input image plane 250, the chapter-dividing designation page number input image plane 230a is displayed on LCD 31. On the designation page number input image plane 230a, so that it is shown that the information setting relating to the chapter-dividing is completed, the chapter title setting display section 232a is reversely displayed. When OK key 233 is pressed on the chapter designation page number input image plane 230a, the applied function operation image plane 220 shown in FIG. 6(b)is displayed on LCD 31. When OK key 222 is pressed on the applied function operation image plane 220, the main operation image plane 210 shown in FIG. 6(a) is displayed on LCD 31.
Further, in step S13, as shown in FIG. 4, the chapter title information operation-inputted by PC2 may also be received from PC2 through the printer controller 10 and set. Furthermore, in addition to the chapter title information, the chapter-dividing page number information or the kind of image information may also be received from PC2 and set. The system memory 130 stores the chapter title information.
Then, it is discriminated whether each kind of setting by the input is completed (step S14). In step S14, for example, in the situation that the main operation image plane 210 shown in FIG. 6(a) is displayed on LCD 31, depending on a case whether the image formation execution button of the hard key of the operation display section 30 is pressed by the user, it is discriminated whether each kind of setting by the user is completed. When each kind of setting is not completed (step S14: NO), the sequence is advanced to step S11. When each kind of setting is completed (step S14: YES), the all-page number counter is set to 0, and stored in the system memory 130 (step S15) Then, the chapter number counter is set to 0, and stored in the system memory 130 (step S16) Then, the all-page number counter stored in the system memory 130 is incremented by 1 and set (step S17). In step S17, the page number is successively selected by 1 from the initial all-page number to the last page number in order. Then, the all-page number counter stored in the system memory 130 is referred, and it is discriminated whether the all-page number is the chapter-dividing designation page number (step S18). When it is the chapter-dividing designation page number (step S18: YES), the chapter number counter stored in the system memory 130 is incremented by 1, and set (step S19).
Then, based on the kind of the image formation set in step S13, it is discriminated whether the chapter title information is image formed (step S20). When the kind of the image formation is a case of the image formation of the all-page of the chapter title information or the image formation of only the chapter top page, it is discriminated that the chapter title information is image formed. When it is not the chapter-dividing designation page number (step S18: NO), the sequence is advanced-to step S20.
When the chapter title information is image formed (step S20: YES), based on the kind of image formation set in step S13, it is discriminated whether only the chapter top page is image formed (step S21). When only the chapter top page is image formed (step S21: YES), the all-page number counter stored in the system memory 130, is referred, and it is discriminated whether the all-page number is the chapter-dividing designation page number (the chapter top page number) set in step S13 (step S22).
When it is the chapter top page number (step S22: YES), the text string compounded to the image data is set to the chapter title information corresponding to the chapter number of the chapter number counter stored in the system memory 130 in the chapter title information inputted in step S13 (step S23). When the only the chapter top page is not image formed (step S21: NO), in order to image form the chapter title information on all pages, the sequence is advanced to step S23.
Then, to the input image data which will be image formed, in the position and the letter size set in steps S11, S12, the text string set in step S23 or step S25 is compounded as the image, and by the printer section 40, the composite image for 1 page is image formed on the next surface of the recording sheet (step S24). The next surface of the recording sheet is the surface of the next recording sheet in the chapter-dividing designation page, and in other cases, the next surface or rear surface of the image formed surface. Further, the input image data is, as shown in FIG. 3, the image data inputted by the reading by the image reading section 20, or the image data inputted by the signal receiving from P02 through the printer controller 10. Further, the composition means that the text string is compounded as the image in the area except the input image data, however, it is not limited to this, it may also be a structure in which the text string is compounded as the image in the area in the input image data.
When the chapter title information is not image formed (step S20: NO), or it is not the chapter top page number (step S22: NO), the text string which is compounded to the image data is set to NULL (there is no data) (step S25), the sequence is advanced to step S24. The text string of NULL is not practically image formed in step S24.
Then, by step S24, it is discriminated whether all pages are image formed (step S26). When all pages are not image formed (step S26: NO), the sequence is advanced to step S17. When all pages are image formed (step S26: YES), the first image forming-processing is ended.
Next, referring to FIG. 8 and FIG. 9, the specific example of the image formation by the first image forming processing is shown. In FIG. 8, the recording sheets a1-a6 on whose all pages, together with the image data, the chapter title information is image formed, are shown.
