It is configured to perform processing (authentication) and to be able to connect and communicate with other Bluetooth-compatible devices wirelessly. The piconet is dynamically or automatically established or extinguished when another Bluetooth-enabled device enters or falls out of the predetermined distance range. The wireless communication unit 16 is not limited to a Bluetooth compatible device, and may be, for example, an IEEE 802.11 compatible device. However, in such a case, a later-described wireless communication unit 27 corresponding to the wireless communication unit 16 also needs to be an IEEE802.11 compatible device.

  The reader / writer 15 transmits / receives data in a contact / non-contact state using a contact / non-contact IC card 26 described later and a so-called non-contact communication method (RFID (Radio Frequency Identification) system). Hereinafter, non-contact communication between the reader / writer 15 and the contact / non-contact IC card 26 will be described. When the reader / writer 15 always transmits an activation signal (electromagnetic wave), and the contact / non-contact IC card 26 and the reader / writer 15 approach to the extent that they can communicate with each other, the contact / non-contact IC The card 26 receives the electromagnetic wave transmitted from the reader / writer 15. When the contact / contactless IC card 26 receives the electromagnetic wave, the contact / non-contact IC card 26 rectifies the carrier wave of the electromagnetic wave to generate a DC power source, and drives the internal circuit. Then, the contact / non-contact IC card 26 performs amplitude modulation and sends a response signal to the reader / writer 15 according to the activation signal. For example, an RFID system such as Felica (registered trademark) or Edy (registered trademark) is employed. The reader / writer 15 transmits the unique Bluetooth address (identification data) of the wireless communication unit 16 to the contact / non-contact IC card 26. In order for one Bluetooth-compatible device to perform the pairing and establish a connection with a connection partner, first, it is within a predetermined range and can be connected to the one Bluetooth-compatible device. The troublesome operation of designating a desired device (image forming apparatus 1) from the addresses of the plurality of devices can be omitted.

  On the other hand, the mobile phone 2 stores a telephone number, image data, and the like, and a control unit 21 having a CPU that controls the entire apparatus, a ROM that records programs, various data, and a RAM that can be written / read at high speed. And a large-capacity flash memory 24. Further, the flash memory 24 stores data such as a list of file names (content data) of images, documents, etc. of the mobile phone 2 and thumbnails of each image.

  Further, the cellular phone 2 according to the present invention includes a base station communication unit 25 that includes a communication interface and communicates with a base station, an operation panel 28 such as a push button that accepts a user operation, a camera that acquires a video by photographing, an audio An input unit 23 such as a microphone for receiving the input, a liquid crystal monitor that outputs video, and an output unit 22 such as a speaker that outputs audio.

  A contact / non-contact IC card 26 and a wireless communication unit 27 are also provided. The contact / non-contact IC card 26 uses a so-called non-contact communication system to transmit / receive data to / from the reader / writer 15 in a contact / non-contact state. As described above, Felica (registered trademark), Edy (registered trademark), and the like are employed. Similarly to the above, the wireless communication unit 27 is compatible with, for example, Bluetooth technology. When another Bluetooth compatible device (for example, the wireless communication unit 16) is within a predetermined short distance (for example, 100 m), Wireless connection and communication with other Bluetooth compatible devices.

  Hereinafter, communication processing and image forming processing of the image forming apparatus 1 and the mobile phone 2 in the communication system, information processing system, and image forming system according to Embodiment 1 of the present invention will be described. An example will be described in which the digital multifunction peripheral is the image forming apparatus 1 according to the present invention, and an image based on the image data stored in the user's cellular phone 2 is printed using the digital multifunction peripheral. 3 and 4 are flowcharts showing processing procedures by the CPUs of the control unit 11 of the image forming apparatus 1 and the control unit 21 of the mobile phone 2. As described above, in the communication system, the information processing system, and the image forming system according to Embodiment 1 of the present invention, the image forming apparatus 1 and the mobile phone 2 are both Bluetooth-compatible devices.

  The CPU of the image forming apparatus 1 determines whether or not the mobile phone 2 is approaching within a predetermined range (step S101). As described above, the image forming apparatus 1 is provided with the reader / writer 15, and the mobile phone 2 is provided with the contact / non-contact IC card 26. The reader / writer 15 of the image forming apparatus 1 always transmits an activation signal (electromagnetic wave). For example, when the user holds the mobile phone 2 over the reader / writer 15 of the image forming apparatus 1, the above-described method is used. A response signal corresponding to the activation signal is sent from the contact / non-contact IC card 26 of the mobile phone 2 to the reader / writer 15. When receiving the response signal, the CPU of the image forming apparatus 1 determines that the mobile phone 2 is approaching within a predetermined range.

  If the CPU of the image forming apparatus 1 determines that the mobile phone 2 is not within the predetermined range (step S101: NO), the CPU waits until the mobile phone 2 approaches the predetermined range. On the other hand, when the CPU of the image forming apparatus 1 determines that the mobile phone 2 is approaching within a predetermined range (step S101: YES), the Bluetooth address of the wireless communication unit 16 (hereinafter referred to as an image forming apparatus side address). .) Is sent to the reader / writer 15, and the reader / writer 15 transmits the image forming apparatus side address (identification data) to the contact / non-contact IC card 26 of the cellular phone 2 (step S102).

  On the other hand, the CPU of the mobile phone 2 monitors the contact / non-contact IC card 26 to determine whether or not the image forming apparatus side address has been received (step S201). If the CPU of the mobile phone 2 determines that the image forming apparatus side address has not been received (step S201: NO), the CPU waits until the image forming apparatus side address is received. When it is determined that the image forming apparatus side address has been received (step S201: YES), the CPU of the mobile phone 2 stores the received image forming apparatus side address in the storage area of the contact / non-contact IC card 26.

  FIG. 5 is an explanatory diagram for explaining the configuration of the storage area of the contact / non-contact IC card 26. The storage area of the contact / non-contact IC card 26 includes a common area 26B and a private area 26A (free area). The received image forming apparatus side address (identification data) is written in the private area 26 A of the contact / non-contact IC card 26. The private area 26A is an area that can be freely used by a service provider. By using the private area 26A, writing with a high degree of freedom becomes possible. On the other hand, it is possible to write data in the common area, but in this case, there is a problem that the network network remote issuing system must be used and the degree of freedom in writing is low.

  Next, the CPU of the mobile phone 2 transmits a pairing request and a later-described mobile phone side address to the image forming apparatus 1 (step S202). In such processing, the wireless communication unit 27 of the mobile phone 2 uses the Bluetooth address of the wireless communication unit 27 (hereinafter referred to as a mobile phone side address) and the data for requesting pairing to the image forming apparatus 1. This is performed by transmitting to the wireless communication unit 16.

  On the other hand, the CPU of the image forming apparatus 1 monitors the wireless communication unit 16 to determine whether a pairing request and the mobile phone side address have been received from the mobile phone 2 (step S103). When the CPU of the image forming apparatus 1 determines that the pairing request and the mobile phone side address are not received (step S103: NO), the pairing request and the mobile phone side address are received from the mobile phone 2. Wait until there is. If the CPU of the image forming apparatus 1 determines that a pairing request and the mobile phone side address have been received (step S103: YES), the received mobile phone side address is stored in the storage unit 14, and the operation panel 12 Is displayed on the display unit 13 (step S104), and the user is requested to input the passkey. The CPU of the image forming apparatus 1 receives a passkey input by the user via the operation panel 12 (or the touch panel of the display unit 13), and temporarily stores the passkey in the storage unit 14.

  Further, the CPU of the image forming apparatus 1 compares the pass key with a pass key stored in advance in the storage unit 14, and if it is determined to be correct, the pairing is completed, and the image forming apparatus 1 and the mobile phone 2 are connected. Are established and are set in a state where they can communicate with each other. On the other hand, if it is determined that it is not correct, a screen to that effect and a prompt to input again is displayed on the display unit 13.

  As described above, when the connection is established, the CPU of the image forming apparatus 1 starts to invalidate the connection establishment request (pairing request) from another apparatus (step S105). That is, when the connection is established, even if the wireless communication unit 16 receives data requesting pairing from another device thereafter, the data is invalidated.

  Thereafter, the CPU of the image forming apparatus 1 shuts off the power supplied to the reader / writer 15 and stops the reader / writer 15 from transmitting the image forming apparatus side address (step S106).

  This makes it possible for a third party to illegally access the mobile phone 2 to tamper with or steal the data in the mobile phone 2 by making use of network communication, simultaneous pairing, etc., for communication using Bluetooth technology. This can be prevented in advance.

  Next, the CPU of the image forming apparatus 1 transmits data requesting data of a list of file names such as images and documents of the mobile phone 2 to the mobile phone 2 via the wireless communication unit 16. The file name list data is requested (step S107).

  On the other hand, when the wireless communication unit 27 receives data requesting the file name list data from the image forming apparatus 1, the CPU of the mobile phone 2 stores the image, document, etc. stored in the flash memory 24. Data in the list of file names is read and transmitted to the image forming apparatus 1 via the wireless communication unit 27 (step S203).

  The CPU of the image forming apparatus 1 acquires the file name list data transmitted from the mobile phone 2 by receiving the data via the wireless communication unit 16 (step S108), and stores it in the storage unit 14.

  Next, the CPU of the image forming apparatus 1 displays a file name list screen for accepting selection of a file desired to be printed from the user based on the file name list data stored in the storage unit 14. 13 (step S109).

  FIG. 6 is an exemplary diagram showing an example of the file name list screen displayed on the display unit 13 of the image forming apparatus 1. On the screen of the file name list, a plurality of file names based on the data of the file name list are, for example, scrolled and selected by the user's operation panel 12 or display unit 13 (touch panel) operation. It is configured to display thumbnails of files. The file name list screen includes soft keys such as “number of copies”, “magnification”, and “print”, and can accept printing conditions such as the number of copies and magnification. . When the selection of the file to be printed and the input of the printing conditions are completed, the user operates the “print” soft key to instruct the start of printing. In such a case, a desired file is selected on the large display unit 13 of the image forming apparatus 1 instead of operating a small key while looking at a small liquid crystal monitor screen of the mobile phone 1. Key operability is improved.

  The CPU of the image forming apparatus 1 determines whether a file selection has been received from the user by monitoring the operation panel 12 and the touch panel of the display unit 13 (step S110). If the CPU of the image forming apparatus 1 determines that the file selection is not received (step S110: NO), the CPU waits until the file selection is received from the user. On the other hand, if the CPU of the image forming apparatus 1 determines that a file selection has been received from the user (step S110: YES), the CPU determines whether a print instruction has been received from the user (step S111). Such determination is performed by the CPU monitoring the operation panel 12 and the touch panel of the display unit 13.

  If the CPU of the image forming apparatus 1 determines that a print instruction has not been received (step S111: NO), the CPU waits until a print instruction is received from the user. On the other hand, if the CPU of the image forming apparatus 1 determines that a print instruction has been received from the user (step S111: YES), it requests the mobile phone 2 for image data of the selected file (hereinafter referred to as a selected file) ( Step S112). The request is made by transmitting data requesting transmission of image data of the selected file to the mobile phone 2 via the wireless communication unit 16.

  On the other hand, the CPU of the mobile phone 2 monitors the wireless communication unit 27 to determine whether or not the image forming apparatus 1 has requested transmission of image data of the selected file (step S204). If the CPU of the mobile phone 2 determines that there is no transmission request for image data of the selected file (step S204: NO), the CPU waits until there is a transmission request for image data of the selected file. On the other hand, if the CPU of the mobile phone 2 determines that there has been a request for transmission of the image data of the selected file (step S204: YES), it reads out the image data of the selected file from the flash memory 24, and via the wireless communication unit 27. To the image forming apparatus 1 (step S205).

  On the other hand, when the CPU of the image forming apparatus 1 receives the image data of the selected file from the mobile phone 2 via the wireless communication unit 16 (step S113), the CPU stores the image data in the storage unit 14.

  Next, the CPU of the image forming apparatus 1 sends the image data stored in the storage unit 14 to the image output unit 19 and instructs the image output unit 19 to print an image based on the image data. An image based on the data is printed (step S114).

  The CPU of the image forming apparatus 1 transmits, to the mobile phone via the wireless communication unit 16, data indicating that the printing has been normally completed or the printing result such as an abnormality has occurred. 2 (step S115).

  On the other hand, the CPU of the mobile phone 2 acquires data for notifying the printing result from the image forming apparatus 1 via the wireless communication unit 27 (step S206) and stores the data in the flash memory 24.

  Next, the CPU of the mobile phone 2 performs output via the output unit 22 based on the data for notifying the printing result stored in the flash memory 24 (step S207). The output may be, for example, displaying text to notify the print result on the liquid crystal monitor of the mobile phone 2, and voice, warning sound, etc. to notify the print result are stored in the mobile phone 2. It may be output via a speaker of the telephone 2.

  After notifying the printing result, the CPU of the image forming apparatus 1 determines whether to end printing (step S116). For this determination, for example, the CPU of the image forming apparatus 1 displays on the display unit 13 an inquiry text “Do you want to finish printing?” And soft keys “YES” and “NO”. This is done by monitoring the operation of the unit 13 (touch panel).

  If the CPU of the image forming apparatus 1 determines not to end printing (step S116: NO), the process returns to the process of step S109, and the file name list screen is displayed again on the display unit 13, and the file to be printed is displayed. Is selected from the user. On the other hand, if the CPU of the image forming apparatus 1 determines to end printing (step S116: YES), it determines whether to end communication (step S117). For such determination, for example, the CPU of the image forming apparatus 1 displays on the display unit 13 the text of an inquiry “Do you want to end communication?” And soft keys “YES” and “NO”. This is done by monitoring the operation of the unit 13 (touch panel).

  When the CPU of the image forming apparatus 1 determines not to end the communication (step S117: NO), the CPU returns to the process of step S116 again. On the other hand, if the CPU of the image forming apparatus 1 determines that the communication is to be ended (step S117: YES), the data indicating that the communication is to be ended is transmitted to the mobile phone 2 via the wireless communication unit 16, thereby enabling communication. Is notified (step S118).

  Next, the CPU of the image forming apparatus 1 deletes the mobile phone side address received in step S103 and the passkey accepted in step S104 from the storage unit 14 (step S119). Therefore, it is possible to prevent a malicious third party from misusing the communication history and stealing the mobile phone side address. It should be noted that the present invention is not limited to the above description, and the “YES” soft key may be regarded as operated when there is no operation of the display unit 13 (touch panel) for a predetermined time.

  Thereafter, the CPU of the image forming apparatus 1 cancels the invalidation of the connection establishment request (pairing request) from another apparatus, which has been started in step S105 (step S120), and ends the process.

  On the other hand, the CPU of the mobile phone 2 outputs, for example, a normal end message in step S207, and then monitors the wireless communication unit 27 to determine whether or not a communication end notification has been received for a predetermined time. Determination is made (step S208). When the CPU of the mobile phone 2 determines that the communication end notification has not been received after the predetermined time has elapsed (step S208: NO), the CPU 2 returns to the process of step S204, and sends a request for image data transmission from the image forming apparatus 1. It is determined whether or not there was. On the other hand, if the CPU of the mobile phone 2 determines that the communication end notification has been received (step S208: YES), the image forming apparatus side address received in step S201 is stored in the contact / non-contact IC card 26. The area is erased (step S209), and the communication is terminated.

  As described above, in the communication system, the information processing system, and the image forming system according to the present invention, the image forming apparatus side address is received from the image forming apparatus 1, and the user uses the image forming apparatus side address. Since data is transmitted to the image forming apparatus 1, it is possible to prevent secret information (for example, address, passkey, etc.) on the mobile phone 2 side from being leaked from the mobile phone 2 against the user's intention. It is. Further, after the communication is completed, the received Bluetooth address (and accepted passkey) of the other party is deleted, so that the Bluetooth address of the image forming apparatus is repeatedly registered in the other party's mobile phone during pairing. Accordingly, it is possible to prevent the resources of the mobile phone from being occupied unnecessarily, and to use the resources of the mobile phone more effectively.

  In the above description of the first embodiment, the case where the passkey is manually input by the user for the reliable setting of the passkey has been described as an example. You may comprise so that it may be performed via the reader / writer 15 of the apparatus 1, and the contact / non-contact IC card 26 of the mobile telephone 2. FIG.

  Note that a device that cannot input a passkey (such as a mouse or a headset) may have a configuration in which the passkey is set to a fixed value or a configuration in which it is not necessary to input the passkey. For example, in the case of a device that cannot input such a passkey, a simple enumerated passkey such as “0000” may be used as a default.

  The CPU of the image forming apparatus 1 receives a notification of connection establishment from the mobile phone 2 via the wireless communication unit 16 (step S304). Thereafter, the CPU of the image forming apparatus 1 starts invalidating a connection establishment request (pairing request) from another apparatus (step S305). That is, when the connection is established, even if the wireless communication unit 16 receives data requesting pairing from another device thereafter, the data is invalidated. Further, the CPU of the image forming apparatus 1 cuts off the power supplied to the reader / writer 15, and stops the transmission of the image forming apparatus side address by the reader / writer 15 (step S306).

  After notifying that the connection has been established, the CPU of the mobile phone 2 reads the image data of the selected file from the flash memory 24 and transmits it to the image forming apparatus 1 via the wireless communication unit 27 (step S405).

  The CPU of the image forming apparatus 1 receives the image data of the selected file from the mobile phone 2 via the wireless communication unit 16 (step S307), and stores the image data in the storage unit 14. Next, the CPU of the image forming apparatus 1 sends the image data stored in the storage unit 14 to the image output unit 19, and instructs the image output unit 19 to print an image based on the image data (step S308).

  The CPU of the image forming apparatus 1 wirelessly communicates data for notifying each printing result according to the printing result when the printing is normally completed or when an abnormality occurs during the printing. The data is transmitted to the mobile phone 2 via the unit 16 (step S309).

  Further, the CPU of the image forming apparatus 1 deletes the mobile phone side address and passkey received in step S303 from the storage unit 14 (step S310). Therefore, it is possible to prevent the mobile phone side address from being stolen by a malicious third party.
