DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Normally, in copying machines, users who try to make copies, not writers who have written original papers, will set printing methods, for instance, will set whether color copies or black/white copies are made; will set how many copies are produced; will set whether original papers are copied in an equi-magnification mode, an enlarge-magnification mode, or a compression-magnification mode.
However, when color original papers are copied in the black/white copying mode, there are some possibilities that intentions of writers who have written these color original papers cannot be reflected thereon.
Also, users who have not so many experiences may possibly set erroneous total numbers of copies.
The invention has been made by considering such a difficult aspect, and therefore can make up such a device that while writers of original images have previously stored printing parameters for designating copies (image formations) into original papers, these original papers may be copied by reflecting thereon intentions of these writers.
FIG. 1 is a diagram for showing examples of N-up printings (will be explained later). FIG. 1A indicates 16 sheets of original papers “A” to “P”. FIG. 1B represents a printing result of a 2-up printing in which 16 sheets of the original papers “A” to “P” are printed on 8 sheets of printing papers every two sheets of the original papers “A” to “P”. Also, FIG. 1C shows a printing result of a 4-up printing which is obtained by furthermore performing the 2-up printing with respect to the printing result indicated in FIG. 1B. Further, FIG. 1D shows a printing result of an 8-up printing which is obtained by furthermore performing the 2-up printing with respect to the printing result indicated in FIG. 1C.
In order to save printing papers at a time of printing, there are some cases that, as illustrated in FIG. 1A to FIG. 1D, plural (N) sheets of original papers are printed together on a single sheet of printing paper (namely, N-up printing).
In this case, for example, as indicated in FIG. 1C, when an original paper has already been printed in the 4-up printing and this original paper is furthermore tried to be printed in the 2-up printing mode, there are some possibilities that images of printed articles may become excessively small (as indicated in FIG. 1D), may become destroyed, and therefore, can be hardly read/discriminated.
In such a case, if the following information has already been stored so as to prohibit another N-up printing, then user friendly conditions may be established. That is, while information that the original paper has already been printed in the 4-up printing (see FIG. 1C) is stored in the original paper (printing paper), the execution of another N-up printing (namely, 8-up printing operation shown in FIG. 1D) may be prohibited, resulting in such user friendly conditions.
The invention has been made by also considering this point. Therefore, according to the invention, a history of image printing operations (image formations) can be read from an original to obtain superior readable/discriminatable printing results.
First Embodiment
A first embodiment of the invention will now be explained.
In an image forming method represented as the first embodiment, a printing parameter for designating a printing method is read from an IC chip, which has been attached to an original paper and then, a printing operation (namely, image formation) is carried out based on this printing parameter.
[Composite Copying Machine 1]
FIG. 2 is a diagram for showing a hardware structure of a composite copying machine 1 to which an image forming method according to the invention is applied, while a control apparatus 2 of this composite copying machine 1 is mainly illustrated.
As shown in FIG. 2, the composite copying machine 1 includes the control apparatus 2 and an apparatus main body 10.
The control apparatus 2 includes a control apparatus main body 20, a communication apparatus 22, a recording apparatus 24 such as an HDD/CD apparatus, a user interface apparatus (UI apparatus) 26, and first and second IC chip interfaces (IC chip IF) 28-1 and 28-2. The control apparatus main body 20 contains a CPU 202, a memory 204, and the like. The user interface apparatus 26 contains either an LCD display apparatus or a CRT display apparatus, and a keyboard/touch panel, and so on. The first and second IC chip interfaces 28-1 and 28-2 contain a first antenna 280-1 and a second antenna 280-2, respectively.
[Apparatus Main Body 10]

As shown in FIG. 3, the apparatus main body 10 includes a paper tray section 12, a print engine 14, a scanner 16, an original feeding apparatus 18, and the like. The print engine 14 prints (forms) images on printing papers 42, which are fed from the paper tray section 12, by way of the xerography technique. The scanner 16 reads an image of an original paper 40. The original feeding apparatus 18 feeds the original paper 40.
In the apparatus main body 10, both the first IC chip IF 28-1 and the first antenna thereof 280-1 are arranged in the vicinity of an original feeding path 102 of the original feeding apparatus 18, through which the original paper 40 is transported.
Also, both the second IC chip IF 28-2 and the second antenna thereof 280-2 are arranged in the vicinity of a printing paper transport path 100 through which the printing papers 42 are transported. It should be understood that both the second IC chip IF 28-2 and the second antenna 280-2 are required in a second embodiment of the invention as to the composite copying machine 1.
Also, the UI (user interface) apparatus 26 is arranged at an upper portion of the apparatus main body 10.
In other words, the composite copying machine 1 may be realized by employing such a hardware structure that both the first and second IC chip IF 28-1, 28-2 and the first and second antennas 280-1, 280-2 are additionally provided in a general-purpose composite copying machine having a function of reading and printing an image of the original paper 40 fed from the original feeding apparatus 18 and another function of transmitting this image in a FAX (facsimile) mode.
It should be noted that as represented in FIG. 3, the control apparatus 2 (see FIG. 2) is actually stored inside the apparatus main body 10.
[Original Paper 40]
FIG. 4 is a diagram for showing an example of the original paper 40 shown in FIG. 2 and FIG. 3.
As shown in FIG. 4, either a color image or a black/white image such as a text and an image, which are designed to be read, or image-formed by the composite copying machine 1, is displayed (printed) on the original paper 40. A first IC chip 3 is applied to this original paper 40 by way of either a pasting method or an embedding method.
[IC Chip 3/IC Chip IF 28]
FIG. 5 is a diagram for schematically showing a structure of the first IC chip 3 shown in FIG. 4.
FIG. 6 is a diagram for schematically showing a structure of the first and second IC chip IF 28-1 and 28-2 shown in FIG. 2 and FIG. 3.
As shown in FIG. 5, the first IC chip 3 includes an antenna 300, a clock reproducing circuit 320, a memory circuit 322, a data transmitting/receiving circuit 324, and a power supply circuit 326.
It should also be noted that when it is so guaranteed that the IC chip 3 of the original paper 40 passes through an area in close proximity to the antenna 280, an IC chip 3 having no antenna 300 may be employed.
When there are a plurality sets of elements having essentially same structural such as the first IC chip IF 28-1 and the second IC chip IF 28-2 in the below-mentioned descriptions, these IC chip IF 28-1 and 28-2 will be abbreviated as a general-termed “IC chip IF 28” hereinafter.
Also, as shown in FIG. 6, the IC chip IF 28 includes a transmission circuit 284, a reception circuit 286, a transmission/reception control circuit 282, a demodulation circuit 288, and a modulation circuit 290.
In accordance with the below-mentioned operations of the respective constituent components employed in the IC chip 3 and the IC chip IF 28, information (data) is written into the IC chip 3 via the IC chip IF 28 in a non-contact manner, and the information (data), which has been stored in the IC chip 3, is read therefrom via the IC chip IF 28 in a non-contact manner.
In the IC chip 3 (see FIG. 5), the power supply circuit 326 rectifies an electromagnetic wave signal supplied via the antenna 300 so as to supply electric power to the respective constituent components of the IC chip 3, while this electric power is required for these constituent components.
The clock reproducing circuit 320 reproduces a clock signal from the electromagnetic wave signal supplied via the antenna 300 from the IC chip IF 28 to output this reproduced clock signal to the memory circuit 322 and the data transmitting/receiving circuit 324.
The memory circuit 322 is, for example, a nonvolatile RAM (random access memory). This memory circuit 322 stores thereinto data indicative of information which is input from the data transmitting/receiving circuit 322 in synchronization with the clock signal input from the clock reproducing circuit 320.
Also, the memory circuit 322 outputs data indicative of the information stored therein with respect to the data transmitting/receiving circuit 324 in synchronization with the clock signal.
To clarify and embody an explanation, in the first embodiment, it should be understood that the following case is assumed as a specific example. That is, in this specific example, a printing parameter (will be discussed later with reference to FIG. 8) capable of designating a printing method of an image has been stored in the memory circuit 322 at a stage that the IC chip 3 is attached to the original paper 40.
The data transmitting/receiving circuit 324 demodulates the electromagnetic wave signal input via the antenna 300 into data to output the demodulated data to the memory circuit 322 in synchronization with the clock signal input from the clock reproducing circuit 320.
Also, the data transmitting/receiving circuit 324 changes the reflection intensity of the electromagnetic wave signal supplied from the IC chip IF 28 in accordance with a value of the data input from the memory circuit 322 in synchronization with the clock signal.
As described above, the data indicative of the information, which has been stored in the memory circuit 322, is transmitted from the IC chip 3 to the IC chip IF 28 with changing the intensity of the reflection signal of the electromagnetic wave signal transmitted from the IC chip IF 28 to the IC chip 3.
In the IC chip IF 28 (FIG. 6), the transmission/reception control circuit 282 controls operations of the respective constituent components of this IC chip IF 28.
Also, this transmission/reception control circuit 282 outputs data input from the control apparatus main body 20 (namely, first printing program 50, which will be discussed later with reference to FIG. 7) to the demodulation circuit 288.
Further, this transmission/reception control circuit 282 outputs data, which has been received by the reception circuit 286 and then has been demodulated by the demodulation circuit 288, to the control apparatus main body 20.
The modulation circuit 290 modulates a high frequency signal (radio frequency signal) based upon data input from the transmission/reception control circuit 282 to produce an electromagnetic wave signal, and then, outputs this produced electromagnetic wave signal to the transmission circuit 284.
The transmission circuit 284 transmits the electromagnetic wave signal via the antenna 280 to the IC chip 3, while this electromagnetic wave signal contains data to be stored in the IC chip 3 and the clock signal.
The reception circuit 286 receives a reflection signal, which is reflected from the IC chip 3, to output this received reflection signal to the demodulation circuit 288.
The modulation circuit 288 demodulates a change of the reflection signal input from the reception circuit 286 into the data transmitted from the IC chip 3 to output the demodulated data to the transmission/reception control circuit 282.
[First Printing Program 50]
FIG. 7 is a block diagram for schematically showing a structure of a first printing program 50, which is executed by the control apparatus 2 (see FIG. 2 and FIG. 3) so as to realize the image forming method according to the invention.
As shown in FIG. 7, the first printing program 50 includes an image reading section 500, a user interface (UI) section 510, a data reading section 520, a parameter selecting section 530, an image processing section 532, and a printing control section 540.
The first printing program 50 is supplied via, for example, a recording medium 240 (see FIG. 2) to the control apparatus 2, and is loaded to the memory 204 so as to be executed.
The first printing program 50 reads a printing parameter for designating a printing method, which has been stored in the IC chip 3 (FIG. 4 and FIG. 5) to print the image read from the original paper 40 on the printing paper 42 in accordance with the read printing parameter. The printing method includes a color copy/black/white copy, a total printing number, equi-magnification/enlargement/compression modes, and an N-up printing mode.
In the first printing program 50, the image reading section 500 controls the constituent components of the apparatus main body 10 such as the original feeding apparatus and the scanner 16 (see FIG. 3) in accordance with a control of the control apparatus main body 20 to read an image of the original paper 40 (FIG. 4).
The UI section 510 receives operation by a user with respect to the UI apparatus 26 (FIG. 2 and FIG. 3), and outputs a printing parameter (will be indicated as “printing parameter (user)”), which has been set by the user to the parameter selecting section 530.
FIG. 8 is a diagram for showing an example of data stored in the IC chip 3. As shown in FIG. 8, data such as a printing parameter (will be indicated as “printing parameter (IC)”), histories and error detection/correction codes thereof are stored in the IC chip 3 (FIG. 4 etc.).
The data reading section 520 controls the first IC chip IF 28-1 (FIG. 2 etc.) so as to read data, which has been stored in the memory circuit 322 (FIG. 5) of the IC chip 3 to output the read data to the parameter selecting section 530.
It should also be noted that a check as to whether or not the data derived from the IC chip 3 can be read properly and another check as to whether or not the IC chip 3 is attached to the original paper 40 may be made by employing the following method. That is, the data reading section 520 may check as to whether or not an error occurs in the read data using the error detection/correction code.
The parameter selecting section 530 (FIG. 7) selects either the printing parameter (IC) input from the data reading section 520 or the printing parameter (user) input from the UI section 510 in response to an operation of the user with respect to the UI section 510, and a check result as to whether or not the IC chip 3 is attached to the original paper 40. Then, this parameter selecting section 530 outputs the selected printing parameter (IC, or user) to the image processing section 532 and the printing control section 540.
In other words, for instance, in such a case that the parameter selecting section 530 can read the printing parameter (IC) from the IC chip 3 attached to the original paper 40 (FIG. 4 etc.) properly, the parameter selecting section 530 selects the printing parameter (IC) with user's agreement. In other cases, the parameter selecting section 530 selects the printing parameter (user) input from the UI section 510. Thereafter, the parameter selecting section 530 outputs the selected printing parameter to the image processing section 532 and the printing control section 540.
The image processing section 532 (FIG. 7) performs a process operation such as enlargement/compression and an N-up image with respect to the image of the original paper 40 (FIG. 4 etc.) input from the image reading section 500 in accordance with the printing parameter input from the parameter selecting section 530. Then, the image processing section 532 outputs the processed image to the printing control section 540.
In other words, for instance, in the case that the printing parameter designates the N-up printing operation with respect to the image input from the image reading section 500, the image processing section 532 performs the image processing operation for the N-up printing operation. Whereas, in the case that the printing parameter designates the enlarging/compressing operation, the image processing section 532 executes the enlarging/compressing process operation with respect to the image input from the image reading section 500.
The printing control section 540 (FIG. 7) controls the constituent components of the apparatus main body 10 such as the paper tray section 12 (FIG. 3) and the print engine 14 in accordance with a printing parameter input from the parameter selecting section 530 to print the processed image obtained by the image processing section 532.
In other words, for example, the printing control section 540 prints the processed image, which is input from the image processing section 532, in either the color print mode or the black/white print mode on the printing papers 42, the quantity of which is designated by the printing parameter, in response to this printing parameter.
[Overall Operation]
Next, overall operation of the composite copying machine 1 (first printing program 50) will be described.
FIG. 9 is a flow chart for describing an operation (S10) of the composite copying machine 1 (namely, first printing program 50; FIG. 7).
As shown in FIG. 9, in a step 100 (S100), the user executes only an operation for commencing a printing operation, or executes both an operation for setting a printing parameter and the operation for commencing the printing operation with respect to the UI apparatus 26 (FIG. 2 etc.).
When the UI section 510 (FIG. 7) receives the operation made by the user and the user sets the printing parameter, this UI section 510 outputs this printing parameter (printing parameter (user)) to the parameter selecting section 530.
In a step 102 (S102), the data reading section 520 controls the first IC chip IF 28-1 (FIG. 2 and FIG. 3) so as to read a printing parameter (printing parameter (IC)) from the original paper 40 (FIG. 4 etc.) transported through the original paper transport path 102.
In a step 104 (S104), the image reading section 500 controls the scanner 16 (FIG. 3) to read an image from the original paper 40 (FIG. 4 etc.) transported via the original paper transport path 102.
In a step 106 (S106), the parameter selecting section 530 (FIG. 7) judges as to whether or not the IC chip 3 is attached to the original paper 40 (FIG. 4 etc.).
When the IC chip 3 is attached to the original paper 40, the first printing program 50 is advanced to a process in a step S110, whereas in other cases, the first printing program 50 is advanced to another process in a step S108.
In the step 108 (S108), the parameter selecting section 530 (FIG. 7) outputs the printing parameter (user) input from the UI section 510 to both the image processing section 532 and the printing control section 540.
In such a case that the user does not clearly set the printing parameter in the above-described process operation of the step S100, the parameter selecting section 530 outputs a printing parameter, which has been set as a default value, to both the printing process unit 532 and the printing control section 540.
The image processing section 532 and the printing control section 540 perform a printing operation with respect to the printing paper 42 (FIG. 2 etc.) in accordance with the printing parameter (user) input from the parameter selecting section 530.
In a step 110 (S110), the parameter selecting section 530 (FIG. 7) judges as to whether or not there is a printing parameter (user), which has been set by the user in the process of the step S100.
When there is the printing parameter (user), which has been set by the user, the first printing program 50 is advanced to a process in a step S112, whereas in other cases, the first printing program 50 is advanced to another process in a step S116.
In the step 112 (S112), the UI section 510 (FIG. 7) displays on the UI apparatus 26 (FIG. 3) a message that a printing operation is carried out in accordance with not the printing parameter (user) set by the user, but the printing parameter (IC) read from the IC chip 3.
In a step 114 (S114), the UI section 510 judges as to whether or not the user executes an operation indicating that the user agrees to the printing operation according to the printing parameter (IC) read from the IC chip 3.
When the user's agreement operation is carried out, the first printing program 50 is advanced to a process in a step S116, whereas in other cases, the first printing program 50 is advanced to another process in a step S118.
In the step 116 (S116), the parameter selecting section 530 (FIG. 7) outputs the printing parameter (IC) read from the IC chip 3 (FIG. 4 etc.) to both the image processing section 532 and the printing control section 540.
The image processing section 532 and the printing control section 540 execute the printing operation with respect to the printing paper 42 (FIG. 2 etc.) in accordance with the printing parameter (IC) input from the parameter selecting section 530.
In the step 118 (S118), the first printing program 50 stops the printing operation.
[Modification]
FIG. 10 is a diagram for showing an example of a structure of a second IC chip 34.
FIG. 11 is a block diagram for showing a structure of a second printing program 52.
As shown in FIG. 10, the second IC chip 34 employs such a structure that an encryption circuit 340 is additionally interposed between the memory circuit 322 and the data transmitting/receiving circuit 324 of the first IC chip 3 (see FIG. 5).
As shown in FIG. 11, the second printing program 52 employs such an arrangement that a decryption section 522 is additionally interposed between the data reading section 520 and the parameter selection unit 530 of the first printing program 50.
It should be understood that the same reference numerals used in the respective structural components of the first IC chip 3 will be employed as those for denoting the essentially same structural components of this second IC chip 34. Furthermore, the same reference numerals used in the respective structural components of the first printing program 50 will be employed as those for denoting the essentially same structural components of the second printing program 52.
In such a case that the first IC chip 3 includes the encryption circuit 340 and the second printing program 52 includes the decryption section 522, in the second IC chip 34, the encryption circuit 340 reads a printing parameter from the memory circuit 322 in synchronization with the clock signal, and then encrypts this read printing parameter to output the encrypted printing parameter to the data transmitting/receiving circuit 324.
The data (printing parameter), which has been encrypted and output, is decrypted by the decryption section 522 in the second printing program 52, and thereafter, the decrypted data is processed in the process operation shown in FIG. 9.
As described above, it is preferable to execute such an operation that while the data is encrypted in the second IC chip 34, the encrypted data is decrypted in the second printing program 52 in order to improve secrecy of information.
Second Embodiment
Next, a description will now be made of a second embodiment according to the present invention.
In an image forming method indicated as the second embodiment, both a printing parameter, which is read out from an IC chip attached to an original paper, and a history of printing operations are written in another IC chip attached to a printing paper.
Further, such a history indicating how an image of the original paper has been so far printed (for instance, conditions of N-up printing operation shown in FIG. 1A to FIG. 1D) is written in the IC chip attached to the original paper, and thus, this written history may be employed in a printing operation.
[Third Printing Program 54]
FIG. 12 is a block diagram for showing a structure of a third printing program 54 capable of realizing the image forming method of the invention, which is executed by the control apparatus 2 (FIG. 2 and FIG. 3), instead of the first printing program 50 shown in FIG. 7.
FIG. 13 is a diagram for showing a printing paper 42 to which the first IC chip 3 has been attached. FIG. 13A shows the printing paper 42 before an image is printed thereon, and FIG. 13B shows the printing paper 42 after the image has been printed thereon.
It should be understood that the same reference numerals are used for the respective constituent components as those for respective constituent components of both the first printing program 50 and the second printing program 52 to denote the essentially same structural components of the third printing program 54.
In the second embodiment, as indicated by using parentheses in FIG. 8, a history of printing operations is additionally written into the first IC chip 3 (FIG. 4 etc.) attached to the original paper 40.
As shown in FIG. 12, the third printing program 54 employs such a structure that a data writing section 524 is additionally provided in the first printing program 50.
In the third printing program 54, the data reading section 520 reads the printing parameter (IC) from the first IC chip 3 attached to the original paper 40 in addition to the history, and then, outputs these read printing parameter (IC) and history to the parameter selecting section 530.
Also, the parameter selecting section 530 selects one of the printing parameter (user), which is input from the UI section 510, the printing parameter (IC) and the history, which are input from the data reading section 520 (there may be a case where only the printing parameter (IC) is stored in the first IC chip 3), and then, outputs the selected one to both the image processing section 532 and the printing control section 540.
Also, the parameter selecting section 530 outputs the one of the printing parameter (user) and the printing parameter (IC) to the data writing section 524.
Similar to the first embodiment, both the image processing section 532 and the printing control section 540 perform a printing operation in accordance with the printing parameter input from the parameter selecting section 530, and furthermore execute a printing operation in accordance with the history input from the parameter selecting section 530, if input.
In other words, for instance, when the history read from the first IC chip 3 indicates that the image of the original paper 40 has been printed in the equi-magnification printing mode, both the image processing section 532 and the printing control section 540 perform the printing operation in one of the equi-magnification printing mode, the 2-up printing mode, the 4-up printing mode (see FIG. 1A to FIG. 1), and the compression printing mode in response to an instruction by the user.
Also, for instance, when the history read from the first IC chip 3 indicates that an image of an original paper 40 has been printed in the 2-up printing mode, both the image processing section 532 and the printing control section 540 perform the printing operation only in either the equi-magnification printing mode or the 2-up printing mode in accordance with an instruction by the user, and also prohibit that the printing operation is carried out in both the 4-up printing operation and the compression printing operation, which may cause such a possibility that printed images of the original paper 40 cannot be read/discriminated.
Also, for instance, when the history read from the first IC chip 3 indicates that an image of an original paper 40 has been printed in the 2-up printing mode, both the image processing section 532 and the printing control section 540 perform a printing operation only in either the equi-magnification printing mode or the 2-up printing mode in accordance with an instruction by the user, and also prohibit that the printing operation is carried out in the 4-up printing operation, which may cause such a possibility that printed images of the original paper 40 cannot be read/discriminated.
Also, similarly, both the image processing section 532 and the printing control section 540 prohibit that a printing operation is carried out in the compressed-magnification mode, which may cause such a possibility that printed images of the original paper 40 cannot be read/discriminated.
Also, for instance, when the history read from the first IC chip 3 indicates that an image of an original paper 40 has been printed in the 4-up printing mode, both the image processing section 532 and the printing control section 540 perform the printing operation only in either the equi-magnification printing mode or the 2-up printing mode in accordance with an instruction by the user.
Furthermore, when the image processing section 532 prints an image on the printing paper 42, this image processing section 532 outputs information indicating that the printing operation has been carried out for the image in the N-up processing operation, the enlarging process operation, or the compressing process operation as a new history to the data writing section 524.
The data writing section 524 controls the second IC chip IF 28-2 (FIG. 2 and FIG. 3) to store both the printing parameter input from the parameter selecting section 530 and the history input from the image processing section 532 into the first IC chip 3 attached to the printing paper 42, as indicated in FIG. 13A and FIG. 13B.
[Overall Operation]
Next, a description is made of overall operation of the composite copying machine 1 (namely, third printing program 54 shown in FIG. 12) according to the second embodiment.
FIG. 14 is a flow chart for describing the overall operation (defined in step S12) of the composite copying machine 1 according to the second embodiment.
As shown in FIG. 14, the third printing program 54 executes a process operation similar to the process operation in the step S10 shown in FIG. 9 in accordance with either the printing parameter (user) set by the user or the printing parameter (IC) and the history, which are read from the IC chip 3 (FIG. 4 etc. to obtain a print result (see FIG. 13B).
After the process operation defined in either the step S108 or the step S116 (FIG. 9) has been carried out, the third printing program 54 (FIG. 12) is advanced to a process in a step S120 of FIG. 14.
In the step 120 (S120), the data reading section 520 controls the second IC chip IF 28-2 in order to read data from the first IC chip 3 attached to the printing paper 42 (FIG. 13B) in synchronization with detecting the first IC chip 3 attached to the printing paper 42, which is transported through the printing paper transport path 100.
In a step 122 (S122), the data reading section 520 judges as to whether or not the first IC chip 3 (see FIG. 13B) is attached to the printing paper 42.
The third printing program 54 is advanced to a process in a step S124 when the IC chip 3 is attached to the printing paper 42, whereas the process operation of this printing program 54 is terminated in other cases.
In a step 124 (S124), the data writing section 524 controls the second IC chip IF 28-2 (FIG. 2 and FIG. 3) in order that the printing parameter input from the parameter selecting section 530 and the history input from the image processing section 532 are written into the first IC chip 3 attached to the printing paper 42 which is fed through the printing paper transport path 100 (FIG. 3). It should be noted that the data writing section 524 may control the second IF chip IF 28-2 to write one of printing parameter and the history into the first IC chip 3.
As previously described, in accordance with the image forming system and the image forming method of the present invention, while utilizing the semiconductor chip from which the data stored thereinto can be read in the non-contact manner, the setting information of the image formation is stored in the original paper, and the image formation can be carried out by employing the stored setting information of the image formation.
Also, in accordance with the image forming system and the image forming method of the invention, while both the setting information of the image formation and the history are stored, when the image, which has been formed on the printing paper, is used to be furthermore formed, both the setting information and the history can be utilized.
