  The present invention relates to an image forming apparatus, a communication system, and a communication method that receive image data from an external apparatus to form an image.

  Recently, mobile phones equipped with camera functions have become widespread and can easily take digital photos anytime, anywhere. In addition, the memory mounted on a mobile phone has increased in capacity, and there are increasing examples of use as a personal storage device that stores data such as digital photographs and business documents. Also, with the downsizing and thinning of mobile phones, so-called card types have been adopted in which the memory of mobile phones is about the size of a fingertip or smaller than the fingertip.

  In Patent Document 1, when the user brings his / her non-contact ID card (or a wireless communication device incorporating the non-contact ID card) close to the card reader / writer unit of the image processing apparatus, the IC chip of the non-contact ID card is: A weak radio wave including a terminal ID indicating the ID of the image processing device, which is always issued from the card reader / writer unit, is received, the terminal ID is acquired, and a non-contact ID card is used using the terminal ID A wireless communication method for transmitting the user ID to the image processing apparatus is disclosed.

  On the other hand, as a method for printing data such as digital photographs and business documents stored in the memory of the mobile phone by the user, the data to be printed (hereinafter referred to as the data to be printed by connecting the memory of the mobile phone directly to the reader of the image forming apparatus) , Print data) to the image forming apparatus to perform printing, and a method to wirelessly transmit print data to an image forming apparatus that can transmit and receive data to and from the mobile phone and perform printing.

  In the case of the method of directly connecting the memory of the mobile phone to the reading device of the image forming apparatus, it is necessary to pull out the card type memory from the mobile phone and insert it into the memory card reader of the image forming apparatus. Further, after the printing is completed, it is necessary to insert a card-type memory into the mobile phone again, which requires a very troublesome work, and after the printing is completed, a memory card reader of the image forming apparatus. There is also a risk of forgetting to remove the memory card.

  In addition, as a method for wirelessly transmitting print data to an image forming apparatus and performing printing, for example, when performing wireless communication using Bluetooth (registered trademark) technology, when performing wireless communication using an RFID system, the mobile phone In some cases, infrared communication is performed between the image forming apparatuses.

  In the case of performing wireless communication using the Bluetooth (registered trademark) technology, an operation for setting (authenticating) both devices to be in a communicable state is required. For example, when both the mobile phone and the image forming apparatus are compatible with Bluetooth (registered trademark) and perform wireless communication using Bluetooth (registered trademark) technology, the other party can perform a setting operation called common pairing (or bonding). Must be specified and both sides must be able to communicate.

  However, the pairing requires complicated and troublesome operations. For example, when the user prints image data in the memory of the mobile phone using the image forming apparatus, the user can use the mobile phone to perform wireless communication within a predetermined radius range (for example, 100 mm). And, as a result of the search, it is necessary to determine the Bluetooth address of the image forming apparatus from among the Bluetooth addresses of the plurality of image forming apparatuses displayed on the display unit of the mobile phone. Is a very difficult task. Even if the discrimination is normally performed, further detailed operation for setting both of them to be communicable is necessary. When the image forming apparatus is a rented image forming apparatus installed in a convenience store, there are many new users, so there are many first wireless communications, and it is necessary to perform the pairing each time.

  On the other hand, when infrared communication is performed between the mobile phone and the image forming apparatus, the user transmits an infrared port of the mobile phone to be printed and an infrared of the image forming apparatus while transmitting the print data wirelessly. A complicated operation for fixing the cellular phone for a predetermined time in a state where the port faces the port is also necessary.

  For example, when performing wireless communication using an RFID system such as Felica (registered trademark) or Edy (registered trademark), the communication speed is low. It is necessary to hold the image forming apparatus for a predetermined time.

  As a method for easily performing these, the wireless communication method of Patent Document 1 and the communication system of Patent Document 2 are known. That is, both the wireless communication method of Patent Document 1 and the communication system of Patent Document 2 use a so-called RFID system, and connect a non-contact ID card (non-contact IC card) to a card reader / writer unit (reader of a personal computer) of an image processing apparatus. When approaching the writer, the user ID of the non-contact ID card (card ID of the non-contact IC card) is automatically transmitted to the image processing apparatus (personal computer). However, the wireless communication method of Patent Document 1 and the communication system of Patent Document 2 have security problems. That is, since the RFID system is widely used in applications such as electronic payment at ticket gates, convenience stores, etc., identity authentication, the non-contact ID card of Patent Document 1 (the non-contact IC of Patent Document 2) When the card) approaches a reader / writer prepared for another use, the user ID of the non-contact ID card (card ID of the non-contact IC card) is automatically sent to the reader / writer against the user's intention. Confidential information may be leaked, and there is a possibility of unauthorized access using the leaked user ID (card ID).

Similarly to the above, the wireless communication unit 27 is compatible with, for example, Bluetooth (registered trademark) technology, and other Bluetooth compatible devices (for example, the wireless communication unit 16) are within a predetermined short distance (for example, 100 mm). In some cases, wireless connection and communication are performed with the other Bluetooth compatible devices.

  Hereinafter, communication processing and image formation processing of the image forming apparatus 1 and the mobile phone 2 in the communication system and information processing 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 a processing procedure by the CPU of the control unit 11 of the image forming apparatus 1, and FIG. As described above, in the communication system and the information processing 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. 6 is an explanatory diagram for explaining the configuration of the flash memory 24. 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 requests the image forming apparatus 1 for pairing (step S202). The request for such a bearing is requested by the wireless communication unit 27 of the mobile phone 2 to pair with the Bluetooth address of the wireless communication unit 27 (hereinafter referred to as a mobile phone side address) using the address of the image forming apparatus. This is performed by transmitting the data to that effect to the wireless communication unit 16 of the image forming apparatus 1.

  On the other hand, the CPU of the image forming apparatus 1 determines whether or not there is a pairing request from the mobile phone 2 by monitoring the wireless communication unit 16 (step S103). If the CPU of the image forming apparatus 1 determines that there is no pairing request (step S103: NO), the CPU waits until there is a pairing request from the mobile phone 2. When the CPU of the image forming apparatus 1 determines that a request for pairing has been made (step S103: YES), the CPU 13 displays a passkey input screen prompting the user to enter a passkey on the display unit 13 of the operation panel 12, and the mobile phone 2 is displayed to the user. Is requested to input a passkey from (step S104).

  The CPU of the image forming apparatus 1 receives a passkey input by the user via the operation panel 28 (or the touch panel of the display unit 13), compares the passkey with a passkey stored in advance in the storage unit 14, and determines that the passkey is correct. If so, communication is established. That is, this completes the pairing, and the image forming apparatus 1 and the mobile phone 2 are set in a communicable state.

  Next, the CPU of the image forming apparatus 1 transmits data requesting data of a list of file names such as images and sentences of the mobile phone 2 to the mobile phone 2 via the wireless communication unit 16 (step S105). ).

  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 images, texts, and the like 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 it via the wireless communication unit 16 (step S106), 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 S107).

  FIG. 7 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.

It is configured to display thumbnails of files. The file name list screen is provided with soft keys such as “number of copies” and “magnification”, 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 on the small liquid crystal monitor screen of the mobile phone 1, so that the image referentiality and Key operability is improved.

  The CPU of the image forming apparatus 1 determines whether or not 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 S108). If the CPU of the image forming apparatus 1 determines that the file selection is not received (step S108: 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 S108: YES), it determines whether a print instruction has been received from the user (step S109). 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 S109: 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 S109: YES), it requests the mobile phone 2 for image data of a selected file (hereinafter referred to as a selected file) ( Step S110). 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 S111), 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 S112).

  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 the occurrence of an abnormality has occurred. 2 (step S113).

  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.

  As described above, in the communication system and the information processing 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. Therefore, 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.

  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 may be configured so that input of the passkey is unnecessary. For example, in the case of a device that cannot input such a passkey, the default is a simple enumerated passkey such as “0000”.
