The CPU 6 receives a return request from the data reading device 200 and transmits a migration request to the data reading device 200. The return request is transmitted to the CPU 6 via the interrupt ASIC 9 when the data reader 200 reads the non-contact IC card. The transition request is transmitted to the data reading apparatus 200 via the interrupt ASIC 9 when an instruction for image reading or an instruction for image formation is not input to the CPU 6 by the predetermined time. The predetermined time can be changed by the user.

  The network I / F 10 is an interface for connecting the image forming apparatus 100 to a network (not shown). For example, the port 14 is an Ethernet (registered trademark) port for connecting to a network. The authentication data storage unit 11 includes an authentication list (data list). In the authentication list, as shown in FIG. 2, a user ID that permits use of the image forming apparatus 100 is registered. The CPU 6 receives the user ID from the data reading device 200 and authenticates the user ID. That is, when the user ID is registered in the authentication list, the CPU 6 gives the user permission to use the image forming apparatus 100. On the other hand, if the user ID is not registered in the authentication list, the CPU 6 does not give the user permission to use the image forming apparatus 100.

  The port 12 is connected to the port 57 of the data reader 200 via a cable according to a corresponding interface. The port 12 and the port 57 are a USB (Universal Serial Bus) interface, an SPI (Serial Peripheral Interface) interface, an IIC (Inter Integrated Circuit) interface, a serial interface, or a parallel interface.

  The power supply unit 3 supplies power to each component of the image forming apparatus 100 and the data reading apparatus 200 in the normal mode, but in the power saving mode, the interrupt ASIC 9 and the network I / F 10 of the image forming apparatus 100 and the data reading are performed. Power is supplied to the device 200.

  If the CPU 6 does not input an image reading instruction or an image forming instruction until the predetermined time has elapsed, the CPU 6 transmits a transition request to the data reading apparatus 200 and switches the operation mode from the normal mode to the power saving mode. . At this time, the CPU 6 controls the power unit 3 to supply power to the interrupt ASIC 9, the network I / F 10, and the data reading device 200. Further, when receiving a return request from the data reading device 200, the CPU 6 switches the operation mode from the power saving mode to the normal mode.

  FIG. 3 is a diagram illustrating a configuration of data included in the non-contact IC card. The data included in the non-contact IC card is, for example, a user ID 31, card type information 32, billing information 33, and the like. The user ID 31, the card type information 32, and the billing information 33 may be encrypted or may not be encrypted. Here, it is assumed that the user ID 31 and the card type information 32 are not encrypted, but the billing information 33 is encrypted.

  The CPU 51 of the data reader 200 reads the user ID 31, card type information 32, and billing information 33 from the non-contact IC card via the radio wave output unit 53 and the antenna 54, and stores them in the buffer 52. The CPU 51 may decrypt the encrypted billing information 33 using the decryption program stored in the memory 56 before transmitting the user ID 31, the card type information 32, and the billing information 33 to the image forming apparatus 100. . In this case, since it is not necessary for the CPU 6 of the image forming apparatus 100 to decrypt the encrypted billing information 33, the load on the image forming apparatus 100 is reduced. On the other hand, the CPU 51 may transmit the encrypted billing information 33 to the image forming apparatus 100 without decrypting it. In this case, the charging information 33 is not falsified, and the security of the charging information 33 is improved. The CPU 6 of the image forming apparatus 100 decrypts the billing information 33 encrypted using the decryption program stored in the system memory 7.

  Similarly, when the user ID 31 and the card type information 32 are encrypted, the CPU 51 may decrypt the encrypted user ID 31 and the card type information 32 using a decryption program stored in the memory 56. Further, the CPU 6 of the image forming apparatus 100 may decrypt the user ID 31 and the card type information 32 encrypted using a decryption program stored in the system memory 7.

  FIG. 4 is a sequence diagram showing the operation of the system 1000.

  First, the CPU 6 of the image forming apparatus 100 notifies the CPU 51 of the data reading apparatus 200 of a shift request when an image reading instruction or an image forming instruction is not input to the CPU 6 by a predetermined time (step S1). ). The CPU 6 switches the operation mode from the normal mode to the power saving mode (step S2). The CPU 51 sets a register in the CPU 51 that the image forming apparatus 100 is in the power saving mode (step S3). At this time, the CPU 51 also switches the operation mode from the normal mode to the power saving mode. That is, the CPU 51 controls the power supply destination and the power supply amount so that the power is supplied to a part of the CPU 51 (including the buffer 52) necessary for detecting the radio wave output unit 53 and the non-contact IC card.

  When the CPU 51 detects a non-contact IC card via the radio wave output unit 53 and the antenna 54 (step S4), the CPU 51 reads out data included in the non-contact IC card and stores it in the buffer 52 (step S5). At this time, if the data included in the contactless IC card includes encrypted data, the CPU 51 may decrypt the encrypted data. The CPU 51 notifies the CPU 6 of a return request via the interrupt ASIC 9 and the ports 13 and 18 (step S6).

  When receiving the return request, the CPU 6 starts the return operation (step S7). For example, the CPU 6 instructs the power supply unit 3 to supply power in the normal mode. When the return operation is completed (step S8), the CPU 6 notifies the CPU 51 of an acquisition request for data stored in the buffer 52 via the interrupt ASIC 9 and the ports 13 and 18 (step S9).

  The CPU 51 outputs the data stored in the buffer 52 to the CPU 6 via the interface IC 8 and the ports 12 and 57 (step S10). The CPU 6 receives the data stored in the buffer 52 and performs user authentication (step S11). Specifically, the CPU 6 determines whether or not the user ID included in the received data is registered in the authentication list. When the user ID included in the received data is registered in the authentication list, the CPU 6 permits the user to use the image forming apparatus 100 as a successful authentication. If the user ID included in the received data is not registered in the authentication list, the CPU 6 does not permit the user to use the image forming apparatus 100 as an authentication failure.

  The CPU 6 notifies the CPU 51 of the result of user authentication (step S12). The CPU 51 displays authentication success or authentication failure (error) on the display unit 55 according to the result of user authentication (step S13).

  FIG. 5 is a block diagram illustrating a configuration of a system 1001 as a first modification of the system 1000. The system 1001 in FIG. 5 is different from the system 1000 in FIG. In FIG. 4, the CPU 6 of the image forming apparatus 100 performs user authentication. However, for example, the server 300 connected to the image forming apparatus 100 may execute user authentication. The server 300 includes a CPU 35, an authentication data storage unit 36, and a port 37. The authentication data storage unit 36 includes an authentication list shown in FIG.

  When the CPU 6 of the image forming apparatus 100 receives the data stored in the buffer 52, the CPU 6 transmits the received data to the server 300. The CPU 35 of the server 300 receives data stored in the buffer 52 from the image forming apparatus 100 and performs user authentication. Specifically, the CPU 35 determines whether or not the user ID included in the received data is registered in the authentication list. When the user ID included in the received data is registered in the authentication list, the CPU 35 notifies the CPU 6 of information indicating successful authentication. When the user ID included in the received data is not registered in the authentication list, the CPU 35 notifies the CPU 6 of information indicating an authentication failure. When the CPU 6 receives the information indicating the authentication success or the authentication failure from the CPU 35, the CPU 6 notifies the CPU 51 of the result of the user authentication.

  Whenever the user ID in the authentication list stored in the authentication data storage unit 11 is registered or updated, the CPU 6 notifies the CPU 35 of information on the registered or updated user ID via the network I / F 10. . The CPU 35 registers or updates the user ID of the authentication list stored in the authentication data storage unit 60 based on the notified user ID information. As described above, the authentication list stored in the authentication data storage unit 36 is synchronized with the authentication list stored in the authentication data storage unit 11.

  Instead, when switching the normal mode to the power saving mode, the CPU 6 may notify the CPU 35 of information on the registered or updated user ID in the authentication list stored in the authentication data storage unit 11. . In this case, even when the authentication list stored in the authentication data storage unit 11 is updated a plurality of times in the normal mode, the normal data is stored in the authentication data storage unit 36 at a time when the normal mode is switched to the power saving mode. The list for authentication is updated. That is, the authentication list stored in the authentication data storage unit 36 is synchronized with the authentication list stored in the authentication data storage unit 11 by one update operation. Therefore, the time for using the network between the image forming apparatus 100 and the server 300 is shortened by updating the authentication list.

  FIG. 6 is a block diagram showing a configuration of a system 1002 as a second modified example of the system 1000. The system 1002 in FIG. 6 differs from the system 1000 in FIG. 1 in that the data reader 200 performs user authentication. The data reading device 200 further includes an authentication data storage unit 60. The authentication data storage unit 60 includes an authentication list shown in FIG.

  Whenever the user ID in the authentication list stored in the authentication data storage unit 11 is registered or updated, the CPU 6 sends the registered or updated user ID information to the CPU 51 via the interface IC 8 and the ports 12 and 57. Notify The CPU 51 registers or updates the user ID in the authentication list stored in the authentication data storage unit 60 based on the notified user ID information. As described above, the authentication list stored in the authentication data storage unit 60 is synchronized with the authentication list stored in the authentication data storage unit 11.

  Instead, when switching the normal mode to the power saving mode, the CPU 6 may notify the CPU 51 of information on the registered or updated user ID in the authentication list stored in the authentication data storage unit 11. . In this case, even when the authentication list stored in the authentication data storage unit 11 is updated a plurality of times in the normal mode, the normal data is stored in the authentication data storage unit 60 at the same time when the normal mode is switched to the power saving mode. The list for authentication is updated. That is, the authentication list stored in the authentication data storage unit 60 is synchronized with the authentication list stored in the authentication data storage unit 11 by one update operation. Therefore, the time for using the communication path (interface) between the image forming apparatus 100 and the data reading apparatus 200 is shortened by updating the authentication list.

  FIG. 7 is a sequence diagram showing the operation of the system 1002.

  First, similar to the operation of the system 1000 of FIG. 4, the operations of steps S1 to S5 are executed. Thereafter, the CPU 51 of the data reading apparatus 200 performs user authentication (step S20). Specifically, the CPU 51 determines whether or not the user ID included in the data stored in the buffer 52 is registered in the authentication list in the authentication data storage unit 60. When the user ID is registered in the authentication list, the CPU 51 displays a successful authentication on the display unit 55 (step S21). On the other hand, when the user ID is not registered in the authentication list, the CPU 51 displays an authentication failure on the display unit 55 (step S21).

  Thereafter, only when the authentication is successful, the CPU 51 notifies the CPU 6 of a return request via the interrupt ASIC 9 and the ports 13 and 18 (step S22). Next, when receiving the return request, the CPU 6 starts the return operation (step S7) and completes the return operation (step S8).

  Thus, in the system 1002, the data reading apparatus 200 executes user authentication. Therefore, when the user is not permitted to use the image forming apparatus 100 (that is, when authentication fails), the image forming apparatus 100 is not restored and wasteful power consumption is suppressed.

  FIG. 8 is a block diagram illustrating a configuration of a system 1003 as a third modification of the system 1000. The system 1003 in FIG. 8 differs from the system 1000 in FIG. 1 in that the server 300 performs user authentication. The server 300 includes a CPU 35, an authentication data storage unit 36, and a port 37. The authentication data storage unit 36 includes an authentication list. The authentication list stored in the authentication data storage unit 36 may be synchronized with the authentication list stored in the authentication data storage unit 11 by the method described above.

  FIG. 9 is a sequence diagram showing the operation of the system 1003.

  First, similar to the operation of the system 1000 of FIG. 7, the operations of steps S1 to S5 are executed. Thereafter, the CPU 51 of the data reading device 200 transmits the data stored in the buffer 52 to the server 300 (step S30). The CPU 35 of the server 300 receives the data stored in the buffer 52 and performs user authentication (step S31). Specifically, the CPU 35 determines whether or not the user ID included in the data stored in the buffer 52 is registered in the authentication list in the authentication data storage unit 36. If the user ID is registered in the authentication list, the CPU 35 notifies the CPU 51 of information indicating successful authentication (step S32). On the other hand, when the user ID is not registered in the authentication list, the CPU 35 notifies the CPU 51 of information indicating an authentication failure (step S32). The CPU 51 displays authentication success or authentication failure on the display unit 55 according to the notified information (step S21).

  Thereafter, only when the authentication is successful, the CPU 51 notifies the CPU 6 of a return request via the interrupt ASIC 9 and the ports 13 and 18 (step S22). Next, when receiving the return request, the CPU 6 starts the return operation (step S7) and completes the return operation (step S8).

  As described above, in the system 1003, the server 300 executes user authentication. Therefore, when the user is not permitted to use the image forming apparatus 100 (that is, when authentication fails), the image forming apparatus 100 is not restored and wasteful power consumption is suppressed.

  FIG. 10 is a block diagram illustrating a configuration of a system 1004 as a fourth modified example of the system 1000. A system 1004 in FIG. 10 is different from the system 1000 in FIG. 1 in that the data reading device 200 includes a power storage unit 65 (power storage unit) and a voltage detection unit 66 (detection unit). Note that the data reading device 200 of the above-described systems 1001 to 1003 may also include the power storage unit 65 and the voltage detection unit 66. Therefore, the following description is applicable to the data reading apparatus 200 of the systems 1001 to 1003.

  The power storage unit 65 is configured by a storage battery or a capacitor, charges the power from the power supply unit 3, and a part of the CPU 51 (buffer 52 is necessary for detecting the radio wave output unit 53 and the non-contact IC card in the power saving mode. Power). The voltage detection unit 66 detects whether or not the power of the power storage unit 65 supplied to the radio wave output unit 53 and a part of the CPU 51 is insufficient in the power saving mode.

  In the power saving mode, the CPU 51 controls the power supply destination and the power supply amount so that the power from the power storage unit 65 is supplied to a part of the CPU 51 necessary for detecting the radio wave output unit 53 and the non-contact IC card. Therefore, the CPU 51 does not supply power to the display unit 55, the memory 56, and a part of the CPU 51 used for data decoding in the power saving mode. Thereby, useless power consumption is reduced.

  Further, the CPU 51 may adjust the interval for reading data included in the non-contact IC card, that is, the interval of radio waves output from the radio wave output unit 53, according to the type of operation mode. For example, in the power saving mode, the CPU 51 increases the interval at which data included in the non-contact IC card is read, that is, the interval between radio waves output from the radio wave output unit 53. As shown in FIG. 11, when the radio wave is output from the radio wave output unit 53 at 100 ms intervals in the normal mode, the CPU 51 sets the radio wave output unit 53 so that the radio waves are output at 200 ms intervals in the power saving mode. Control. Thereby, power consumption is reduced. Conversely, the CPU 51 reduces the interval of reading data contained in the non-contact IC card, that is, the interval of radio waves output from the radio wave output unit 53 in the normal mode.

  When the voltage detection unit 66 detects that the power of the power storage unit 65 supplied to a part of the radio wave output unit 53 or the CPU 51 is insufficient in the power saving mode, the voltage detection unit 66 sets the CPU 51 to Outputs a signal indicating power shortage. The CPU 51 notifies the CPU 6 of a signal indicating power shortage via the interrupt ASIC 9 and the ports 13 and 18. The CPU 6 controls the power supply unit 3 so as to supply electric power necessary for some operations of the radio wave output unit 53 and the CPU 51. Thereby, even when the power of the power storage unit 65 is insufficient in the power saving mode, the radio wave output unit 53 and a part of the CPU 51 become operable.

  In the systems 1000 to 1004, a non-contact IC card is used as a portable member, but a contact IC card, a magnetic card, or the like may be used. In this case, the data reading device 200 includes a card reader that reads data from a contact IC card or a magnetic card, instead of the radio wave output circuit 53 and the antenna 54.

  As described above, according to FIG. 4, the radio wave output circuit 53 and the antenna 54 read the data stored in the contactless IC card, and the buffer 52 stores the read data. Then, when the data stored in the non-contact IC card is read, the CPU 51 instructs the image forming apparatus 100 to return from the power saving mode to the normal mode. On the other hand, after the image forming apparatus 100 returns to the normal mode, the CPU 6 acquires the data stored in the buffer 52 and performs user authentication based on the acquired data and the prepared data list. In other words, when the data stored in the non-contact IC card is read, the image forming apparatus 100 returns from the power saving mode to the normal mode and performs user authentication. Therefore, the user can execute the return instruction from the power saving mode and the start instruction of the authentication operation with one action (for example, an operation of bringing the non-contact IC card closer to the antenna 54).

  According to FIG. 7, the radio wave output circuit 53 and the antenna 54 read data stored in the non-contact IC card, and the buffer 52 stores the read data. Then, the CPU 51 performs user authentication based on the data stored in the buffer 52 and the prepared data list, and when the user authentication is successful, the image forming apparatus 100 is returned from the power saving mode to the normal mode. Instruct. Therefore, the user can execute the return instruction from the power saving mode and the start instruction of the authentication operation with one action (for example, an operation of bringing the non-contact IC card closer to the antenna 54).

  The above-described implementation can also be realized by supplying a recording medium in which a software program for realizing the function of the data reading apparatus 200 is recorded to the data reading apparatus 200 and the CPU 51 reads and executes the program stored in the storage medium. The same effect as that of the embodiment is produced. Examples of the storage medium for supplying the program include a CD-ROM, a DVD, or an SD card.

  In addition, the data reading device 200 can achieve the same effect as the above-described embodiment by executing a software program for realizing the function of the data reading device 200.
