Description

  The present invention relates to a copying machine capable of accessing a storage medium such as an RFID (Radio Frequency IDentification) tag. More specifically, the present invention relates to a copying machine having a function of copying a document (hereinafter referred to as “RFID document” for convenience) attached with a storage medium (hereinafter referred to as “RFID tag” for convenience).

Conventionally, use of an RFID document in which user information, image information, and the like are stored in an RFID tag has been studied. Due to the nature of RFID manuscripts, data stored in RFID tags and images on paper are often associated with each other, and the importance of stored data and images tends to be high. As a technology related to a copying machine that can access an RFID tag, for example, in Patent Document 1, both an image formed on a sheet and data in an RFID tag attached to the sheet of the RFID document are disclosed. , A technology for copying to a sheet with an RFID tag attached is disclosed.
JP 2002-337426 A

  However, the conventional copying machine described above has the following problems. That is, an RFID document may have images formed on both sides. An RFID manuscript with images formed on both sides (hereinafter referred to as “RFID double-sided manuscript” for the sake of convenience) cannot be correctly copied onto a paper attached with an RFID tag (hereinafter referred to as “RFID paper” for the sake of convenience). is there. For example, when copying an RFID double-sided document, it is necessary to instruct double-sided scanning. However, if a single-sided copy is instructed when copying an RFID double-sided document, the image will be duplicated on only one side, even though the double-sided data is duplicated on the RFID tag. The image of the face will be lost. In other words, when copying a double-sided RFID document using a conventional copying machine, data is lost, and there is a risk that consistency cannot be ensured between the double-sided RFID document that is the copy source and the RFID sheet that is the copy.

  The present invention has been made to solve the problems of the conventional copying machines. That is, the problem is to provide a copying machine that can easily ensure consistency between the RFID double-sided original document that is the copy source and the RFID sheet that is the copy.

  In order to solve this problem, a copying machine includes a reading unit that reads images on both sides of a document, a forming unit that forms an image read by the reading unit on a sheet, and data in a storage medium attached to the document. An acquisition means for acquiring data, a writing means for writing at least a part of the data acquired by the acquisition means to a storage medium attached to the paper, a data acquisition means for acquiring data from the original storage medium, and a writing means When the copying is instructed to write the data on the storage medium of at least one sheet, the judging means for judging whether or not there is an image on both sides of the document, and the judging means are arranged on both sides of the document. If it is determined that there is an image, (A) images on both sides of the original are formed on both sides of the paper, and the same data as the data on the original is written on the storage medium of the paper. (B) original The image on the front side and the image on the back side are respectively formed on different sheets, and the same data as the data on the original storage medium is written on the storage medium of each sheet. Are formed on different sheets of paper, and are written on the storage media of each sheet so that the data written on each storage medium is complemented to be the same data as that of the original storage medium. , And control means for controlling the forming means and the writing means so as to execute any one of the three operation modes (A), (B), and (C).

  The copying machine of the present invention has a data copy function of a recording medium, which is a process for acquiring data from a document storage medium (for example, an RFID tag) and writing the data to at least one sheet of storage medium. . In addition to a user instruction, a copy instruction may be stored in a storage medium, for example, and may be read. When copying is instructed, it is determined whether there are images on both sides of the document. When there are images on both sides of the document, one of the three operation modes (A), (B), and (C) is executed. Each of the operation modes is an operation mode of copying a document with a recording medium. The image of the document and the data on the storage medium are copied on one sheet or divided into a plurality of sheets.

  That is, the copying machine of the present invention first determines whether there are images on both sides of the document when an instruction to copy the storage medium is given. If it is determined that there are images on both sides, one of the above operation modes (A), (B), and (C) is executed. In these operation modes, a double-sided image of a document is formed separately on both sides of one sheet or one side of two sheets, and data on the document storage medium is stored on one sheet or two sheets. Write. Thus, an output product in which both image data and storage medium data are stored can be obtained with certainty. In other words, since the operation mode (A) is a complete copy that outputs the same information as the original, the original data is not lost. The operation modes (B) and (C) are divided into two sheets, and the information for each sheet is incomplete, but the image data and the storage medium data are all obtained by combining the two sheets. Will do. As a result, highly reliable duplication processing can be realized without losing data of the original.

  Further, the control means of the copying machine of the present invention can execute at least the operation mode (A), and the operation mode (A) when information satisfying a predetermined condition is stored in the document storage medium. Better to run. That is, for example, for a document that is regarded as having a high degree of importance, duplication according to the operation mode (A) is executed by storing predetermined information in a storage medium in advance. For example, when information indicating a high degree of importance (for example, a character string “completely duplicated”) is written in the storage medium, the execution of the operation modes (B) and (C) is restricted, and the operation mode Only (A) is executed. In the operation mode (A), unlike the operation modes (B) and (C), the document information (image and data on the storage medium) is completely duplicated on one sheet. For this reason, data is not incomplete due to loss of the other side, and management is easy.

  In the operation mode (C) of the control means, it is better that there is no duplication in the data written on the storage medium of each sheet. That is, when the data on the storage medium is divided and stored, it is possible to store the data in duplicate, but by storing the data without duplication, the amount of data written to each storage medium can be reduced.

  In the operation mode (C) of the control means, it is better to write information indicating the presence of the storage medium of the other sheet in the storage medium of one sheet. For example, the storage medium storing the first half of the data can indicate the presence of another storage medium by storing the character string “first half”. Moreover, you may memorize | store a common recognition symbol in a mutual storage medium. By writing such information, it can be recognized that the data is divided.

  In the operation mode (C) of the control means, the data corresponding to the front surface and the data corresponding to the back surface are specified, the data corresponding to the front surface is written in the storage medium of the paper on which the image of the front surface is formed, and It is better to write the corresponding data in the storage medium of the paper on which the back side image is formed. That is, by writing appropriate data to the paper image on the paper storage medium, the data is easy to use.

  The control means of the copying machine of the present invention can execute at least two operation modes (A), (B), and (C), and registers an option of which operation mode to execute, It is better to operate according to the registered contents. That is, by registering the operation mode, it is not necessary to select each time a copy is instructed. Therefore, it is possible to save the trouble of setting the operation mode at the time of duplication instruction.

  In the copying machine of the present invention, it is better to determine whether or not the document has a storage medium before reading the image of the document, and if there is a storage medium, the reading operation of the document is preferably limited to duplex reading. . That is, the manuscript to which the storage medium is attached tends to be highly important. Therefore, double-sided scanning is performed when copying the data of the storage medium attached to such a document. As a result, proper management of data can be expected.

  According to the present invention, it is possible to realize a copying machine that can easily ensure consistency between an RFID double-sided document as a copy source and an RFID sheet as a copy.

It is a route. A slit 29 provided in the case of the ADF 22 is provided to feed a part of the document out of the ADF 22 and to reverse the document.

  Specifically, a switchback roller 281, a first guide flap 282, and a second guide flap 283 are provided inside the ADF 22, and constitute a conveyance path 28. That is, the conveyance path 28 is a path from the first guide flap 282 to the switchback roller 281 via the second guide flap 283.

  In double-sided scanning by the ADF 22, the image is fed from the document tray 221, and a surface image is read at a reading position via various rollers. Thereafter, the document is guided to the conveyance path 28 by the first guide flap 282 and conveyed to the switchback roller 281 via the second guide flap 283. Then, the document transport direction is reversed by the switchback roller 281. At this time, the directions of the first guide flap 282 and the second guide flap 283 are switched. Then, the document is conveyed again to the conveyance path 27 by the second guide flap 283 and guided to the reading position to read the image on the back surface. As a result, the front and back of the document are reversed and the image on the back side is read. Thereafter, the document is discharged from the discharge roller 274 to the discharge tray 222 via the first guide flap 282.

  In addition, the ADF 22 includes an R / W device 51 (an example of an acquisition unit) that can detect an RFID tag that exists within a predetermined range and can read and write data to and from the RFID tag. The R / W device 51 is arranged in a range where the RFID tag can be accessed when the RFID document is placed on the document tray 221.

[Configuration of image forming unit]
The image forming unit 10 forms an image based on image data sent from an information terminal device such as a personal computer (PC) or image data of a document read by the image reading unit 20, and prints the image on paper. . The image forming unit 10 according to this embodiment forms an image by a known electrophotographic method, and as shown in FIG. 3, a process unit 50 for forming an image and a fixing device 8 for fixing an unfixed toner image. A paper feed cassette 91 for placing paper before image formation, and a paper discharge tray 92 for placing paper after image formation.

  In the image forming unit 10, the paper stored in the paper feed cassette 91 located at the bottom passes through the paper feed roller 73, the process unit 50, and the fixing device 8, and passes through the paper discharge roller 74 to the upper paper discharge tray. A substantially S-shaped conveyance path 71 is provided so as to be guided to 92. That is, the image forming unit 10 takes out the sheets placed in the sheet feeding cassette 91 one by one, conveys the sheets to the process unit 50, and transfers the toner image formed by the process unit 50 to the sheets. To do. Further, the sheet on which the toner image is transferred is conveyed to the fixing device 8 and the toner image is thermally fixed on the sheet. Then, the sheet after fixing is discharged to a paper discharge tray 92.

  The process unit 50 includes a photosensitive member 1, a charging device 2 that uniformly charges the surface of the photosensitive member 1, an exposure device 3 that irradiates light on the surface of the photosensitive member 1 to form an electrostatic latent image, and a static device.

  In the process unit 50, the surface of the photoreceptor 1 is uniformly charged by the charging device 2. Thereafter, exposure is performed with light from the exposure device 3, and an electrostatic latent image of an image to be formed on the paper is formed. Next, toner is supplied to the photoreceptor 1 via the developing device 4. Thereby, the electrostatic latent image on the photoreceptor 1 is visualized as a toner image.

  Further, the image forming unit 10 is provided with a double-sided printing mechanism for printing on both sides of the paper. A conveyance path 72 in FIG. 3 is a conveyance path for reversing the sheet and re-conveying it to the process unit 50 so that printing is performed on the other side of the sheet printed on one side. is there.

  In double-sided printing by the image forming unit 10, the paper on which the image is formed on the front surface is stopped by the paper discharge roller 74 via the transport path 71 which is the front surface transport path (normal transport path), and the transport direction of the paper is reversed. . Then, the paper is transported from the paper discharge roller 74 to a transport path 72 that is a re-transport path, passes through a position between the process unit 50 and the paper feed cassette 91, and is guided to the process unit 50 again. As a result, the front and back sides of the paper are reversed, and an image is formed on the back side.

  In addition, the image forming unit 10 detects an RFID tag existing within a predetermined range, and an R / W device 52 (an example of a writing unit) that can read and write data to the RFID tag. I have. The R / W device 52 is disposed in a range where the RFID tag can be accessed when the RFID sheet is conveyed on the conveyance paths 71 and 72.

[Electric configuration of MFP]
Next, the electrical configuration of the MFP 100 will be described. As illustrated in FIG. 4, the MFP 100 includes a control unit 30 including a CPU 31, a ROM 32, a RAM 33, an NVRAM 34, an ASIC 35, a network interface 36, and a FAX interface 37.

  The CPU 31 executes arithmetic operations for realizing various functions such as an image reading function and an image forming function in the MFP 100, and is the center of control. The ROM 32 stores various control programs for controlling the MFP 100, various settings, initial values, and the like. The RAM 33 is used as a work area from which various control programs are read or as a storage area for temporarily storing image data. An NVRAM (Non Volatile RAM) 34 is a non-volatile storage means and is used as a storage area for storing various settings or image data.

  The CPU 31 stores each processing result in the RAM 33 or the NVRAM 34 in accordance with a control program read from the ROM 32 and signals sent from various sensors, and turns on each component of the MFP 100 (for example, lighting timing of the exposure apparatus constituting the image forming unit 10). A drive motor (not shown) for various rollers constituting the paper conveyance path and a moving motor (not shown) for the image sensor unit constituting the image reading unit 20 are controlled via the ASIC 35.

  The network interface 36 is connected to a network such as the Internet, and enables connection with an information processing apparatus such as a PC. The FAX interface 37 is connected to a telephone line and enables connection with a destination FAX apparatus. Jobs can be exchanged via the network interface 36 or the FAX interface 37.

[Replication process]
Next, a duplication process in MFP 100 will be described. MFP 100 has an RFID tag data duplication function (acquisition of RFID tag data and writing of the obtained data) in addition to an original image duplication function (image reading of an original and image formation of the read image data). Yes. In the following description, a replication process when there is an RFID tag replication instruction by single-sided copying will be described.

  In MFP 100, the operation mode of RFID tag duplication by single-sided copying is set in advance before duplication instruction. In this embodiment, a setting screen as shown in FIG. 5 is displayed on the display unit 41 of the operation panel 40 to prompt the user to select an operation mode. The operation mode is set by the user selecting one operation mode with the radio button 411.

  Specifically, in the present embodiment, the following four operation modes can be selected. The first mode is an operation mode in which an image of an RFID double-sided document is printed on both sides of a single RFID sheet, and the RFID tag data of the document is fully copied to the RFID tag of the sheet (hereinafter referred to as “operation mode A”). And). That is, in the operation mode A, even if a single-sided copy instruction is given, the images on both sides of the RFID double-sided document 81 are duplicated on both sides of the RFID paper 85 as shown in FIG. Further, all data of the RFID tag 82 of the RFID double-sided document 81 is copied to the RFID tag 86 of the RFID paper 85. In the operation mode A, the duplication of the double-sided image of the original and the entire duplication of the RFID tag are performed on one RFID sheet, so that no data is lost.

  The second is an operation mode (hereinafter referred to as “operation mode B”), in which an image of an RFID double-sided original is divided into two RFID sheets and printed on one side, and the RFID tag data of the original is fully copied to the RFID tag of each sheet. ”). That is, in the operation mode B, as shown in FIG. 7, the images on both sides of the RFID double-sided document 81 are divided into the RFID paper 85 and the RFID paper 87 and duplicated on each side. Further, all the data of the RFID tag 82 of the RFID double-sided document 81 is copied to the RFID tag 86 of the RFID paper 85 and the RFID tag 88 of the RFID paper 87. In the operation mode B, the image of the document is formed separately on two sheets, but the images on both sides of the document are recorded when the sheets complement each other. Further, since all copying is performed on the RFID tag of each sheet, no data is lost.

  Third, the image of the RFID double-sided document is printed on one side on two RFID sheets, the RFID tag data of the document is partially copied to the RFID tag on each sheet, and all the data is held by both RFID tags. Operation mode (hereinafter referred to as “operation mode C”). That is, in the operation mode C, as shown in FIG. 8, the images on both sides of the RFID double-sided document 81 are divided into the RFID paper 85 and the RFID paper 87 and duplicated on each side. Further, all the data of the RFID tag 82 of the RFID double-sided document 81 is divided into two, and the divided data are copied to the RFID tag 86 of the RFID paper 85 and the RFID tag 88 of the RFID paper 87, respectively. Information indicating that the data is divided (for example, “before”, “after”) is added to the divided data. In the operation mode C, in addition to the original image being divided and formed on two sheets of paper, the RFID tag data is also divided into two parts. Same as data. Therefore, no data loss occurs. Further, the amount of data to be written is smaller than that of the operation mode B in which all data is written.

  The fourth mode is an operation mode (hereinafter referred to as “operation mode D”) in which an image of an RFID double-sided original is printed on one side of two RFID sheets and the RFID tag data is not duplicated. That is, RFID tag data tends to be highly important. Therefore, in the operation mode D, the importance of the RFID tag data is taken into consideration, and in the case of an incomplete duplication instruction (that is, an instruction for one-sided copying despite being an RFID double-sided original), the RFID tag data is duplicated. Do not do. The operation mode D is a mode in which safety is more important than data integrity.

  The selection result by the user is registered in MFP 100. That is, the selection result is stored in the NVRAM 34. Then, MFP 100 performs an operation when there is an RFID tag duplication instruction by single-sided copying according to the registered content. In the initial state, the operation mode A is set as default, and the operation mode A is preferentially selected in a state where there is no selection by the user.

  Hereinafter, with reference to the flowchart of FIG. 9 for the procedure of duplication processing (an example of reading means, forming means, acquisition means, writing means, determination means, and control means) when there is an RFID tag duplication instruction by single-sided copying. However, it will be explained. This process is executed in response to an instruction to copy the RFID tag by the user.

  First, the RFID tag data attached to the document is acquired by the R / W device 51 of the image reading unit 20 (S101). Next, it is determined whether or not the RFID tag data has been acquired, that is, whether or not the RFID tag is attached to the document (S102).

  If the RFID tag data cannot be obtained (S102: NO), the RFID tag data cannot be copied. Therefore, only one-sided copying of the original image is performed. That is, only the image on the front side of the document is read (S121), only the image on the front side is formed on the paper (S122), and this process is terminated.

  If the RFID tag data can be acquired (S102: YES), the document is scanned on both sides (S103). Then, the read image is analyzed to determine whether there is an image on the back side of the document (S104). If there is no image on the back side (S104: NO), the image data is not lost even if it is a single-sided copy of only the front side. Therefore, the R / W device 52 of the image forming unit 10 writes all the RFID tag data acquired in S101 to the RFID tag attached to the sheet (S141). Then, only the front image is formed on the sheet (S142). That is, the RFID tag data is copied by single-sided copying as instructed by the user.

  If there is an image on the back side (S104: YES), image data is lost in the single-sided copy of only the front side. Accordingly, it is determined whether or not specific information is included in the RFID tag data acquired in S101 (S105). In this embodiment, it is determined whether or not the RFID tag data includes information of “complete duplication” meaning the operation mode A. When the information of “complete replication” is included (S105: YES), the operation of the operation mode A is performed. That is, all data of the RFID tag is written in the RFID tag attached to the paper (S161), and images are formed on both sides of the paper (S162). That is, when “completely duplicated” information is extracted, the operation of the operation mode A is performed with priority over the setting stored in the MFP 100. Thereby, the operation mode can be determined by an instruction from the RFID tag.

  If the “complete copy” information is not included (S105: NO), the image and RFID tag data are recorded in accordance with the operation mode registered in the MFP 100 (S106).

  FIG. 10 is a flowchart showing the procedure of the recording process in S106. In this recording process, first, an operation mode registered in the MFP 100 is acquired (S201). Next, it is determined whether or not the registered operation mode is the operation mode A (S202). If it is the operation mode A (S202: YES), all data of the RFID tag is written in the RFID tag attached to the paper (S221). Then, images are formed on both sides of the paper (S222). That is, the image and RFID tag data are recorded on one RFID sheet.

  If the registered operation mode is not the operation mode A (S202: NO), it is determined whether or not it is the operation mode B (S203). If it is the operation mode B (S203: YES), all the data of the RFID tag of the document is written to the RFID tag of the first sheet (S241). Then, an image of the surface of the original is formed on the paper (S242). Next, all the data of the RFID tag of the document is also written to the RFID tag of the second sheet (S243). Then, an image of the back side of the document is formed on the paper (S244). That is, the double-sided image of the original is divided into two sheets and copied on one side, and all data of the original RFID tag is written in the RFID tag of each sheet.

  If the registered operation mode is not the operation mode B (S203: NO), it is determined whether or not it is the operation mode C (S204). In the case of the operation mode C (S204: YES), the first half of the RFID tag data of the document and the information indicating that all data is combined with the second half of the data are stored in the RFID tag of the first sheet. Write (S261). Then, an image of the surface of the original is formed on the paper (S262). Next, data indicating the latter half of the RFID tag of the document and information indicating that all data is combined with the first half are written to the RFID tag of the second sheet (S263). Then, an image of the back side of the document is formed on the paper (S264). That is, the double-sided image of the original is divided into two sheets and copied on one side, and the RFID tag data of the original is written in two on the RFID tag of each sheet.

  In the operation mode C, it is preferable to divide the RFID tag data in correspondence with the image on the front surface and the image on the back surface. For example, when problems 1 to 10 are described on the front surface, problems 11 to 20 are described on the back surface, and answers of problems 1 to 20 are stored in the RFID tag, an image of the front surface is formed. The first paper RFID tag stores the answers 1 to 10 and the second paper RFID tag on which the back side image is formed stores the answers 11 to 20 answers. . This improves the usability of the duplicated paper. In this case, the RFID tag stores in advance information that can identify whether the data corresponds to the image on the front side or the data on the back side.

  Further, the RFID tag data need not necessarily be divided into two equal parts. That is, it suffices if all data of the RFID tag of the document can be held by complementing the two divided data, and the storage ratio is not limited. That is, as shown in FIG. 11, all data is stored in the RFID tag 86 of the first sheet 85, and the RFID tag 86 of the first sheet 85 is stored in the RFID tag 88 of the second sheet 87. Only information for reference may be stored.

  If the registered operation mode is not the operation mode C (S204: NO), it can be determined that it is the operation mode D. Therefore, the image on the front side of the document is formed on the first sheet (S205), and the image on the back side of the document is formed on the second sheet (S206). That is, this process is terminated without accessing the RFID tag.

  In this embodiment, the operation mode is registered in MFP 100 in advance, and after the copy instruction, the operation mode is automatically determined according to the registered content. However, the user may manually determine the copy mode every time a copy instruction is issued. In this case, for example, instead of the process of acquiring the operation mode registered in MFP 100 in S201, a screen for receiving selection of the operation mode (for example, the setting screen shown in FIG. 5) is displayed, and the selection from the user is received. Thereafter, it may be operated according to the user's selection.

  As described in detail above, the MFP 100 according to the present embodiment determines whether or not there is an image on both sides of a document when copying RFID tag data. Regardless of the setting, one of the operation modes A, B, C, and D is executed. Among these operation modes, in operation modes A, B, and C, a double-sided image of a document is formed separately on both sides of one sheet or one side of two sheets, and the RFID tag data of the document is Write on one sheet or two sheets. Thus, in the duplication processing of MFP 100, an output product in which both image data and RFID tag data are stored can be obtained with certainty. That is, since the operation mode A is a complete copy in which a document having the same information as the original is output, both data are not lost. The operation modes B and C are divided into two sheets, and the information for each sheet is incomplete, but the image data and the RFID tag data are all obtained by combining the two sheets. . As a result, it is possible to realize a highly reliable copy process without losing data of the original document that is the copy source.

  Note that this embodiment is merely an example, and does not limit the present invention. Therefore, the present invention can naturally be improved and modified in various ways without departing from the gist thereof. For example, the present invention is not limited to a multi-function peripheral (MFP), but can be applied to a copying machine or the like that has a document reading function and an image forming function. Further, the image forming method of the image forming unit is not limited to the electrophotographic method, and may be an ink jet method. Further, even if a color image can be formed, it may be dedicated to a monochrome image.

  In the embodiment, the R / W device 51 for accessing the RFID tag of the document and the R / W device 52 for accessing the RFID tag of the paper are provided, respectively. Both the RFID tag and the paper RFID tag may be accessible.

  In the embodiment, four operation modes can be selected. However, all four operation modes are not essential. For example, there may be only three options. Also, one of the operation modes A, B, and C may be operable and may not have an operation mode selection function. That is, as long as at least one of the operation modes A, B, and C can be operated, the data on the RFID double-sided original can be copied without loss. For example, it may be configured to execute only the operation mode A in order to support only complete replication. Further, when the image forming unit 10 does not support double-sided printing, only the operation modes B and C may be executed.
