  Hereinafter, each embodiment of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.

[Embodiment]
In FIG. 1, an image forming apparatus 100 is a copying machine, a printer, a facsimile machine, a multifunction machine, or the like. The multifunction machine has a copy function, a print function, a fax function, and the like. The image forming apparatus 100 includes an image reading unit 200 and an image forming unit 300.

  As shown in FIG. 2, the image reading unit 200 includes a contact unit 1, a document cover 2, an image sensor 3, and the like. A document (not shown) to be image-read is placed on the contact unit 1. The document cover 2 is provided on the upper surface of the housing 10 of the image forming apparatus 100 so as to be openable and closable, and presses the document on the contact portion 1 from above. The image sensor 3 optically reads the original while moving to the right of the image forming apparatus 100 under the contact portion 1 inside the housing 10 under the control of the control unit 12 (see FIG. 3). . The image sensor 3 generates document image data representing the document and transmits it to the control unit 12. The document image data is an example of image data in the present invention.

  As shown in FIG. 3, the image forming unit 300 is provided inside the housing 10 and includes an image carrier 4, a charging unit 5, an exposure unit 6, a developing unit 7, a transfer unit 8, and a fixing unit 9. The image forming unit 300 forms a toner image based on the document image data by electrophotography under the control of the control unit 12. The image forming unit 300 further transfers the toner image onto a sheet (for example, paper) and fixes it, and then discharges the toner image as a printed matter outside the image forming apparatus 100. Note that the image forming unit 300 may form an image based on the document image data by an inkjet method.

  As shown in FIG. 1, the image forming apparatus 100 further includes an operation display unit 11. The operation display unit 11 is an example of a display device in the present invention. The operation display unit 11 is provided on the upper side on the front side of the housing 10. Specifically, the operation display unit 11 is provided in front of the contact unit 1 and the image sensor 3 (see FIG. 2). As shown in FIG. 4, the operation display unit 11 includes a display unit 21, a touch panel 22, an attachment unit 23, a card reader 24, and an operation input unit 25.

  The display unit 21 is disposed above the mounting unit 23 described later in the housing 10. The display unit 21 has a screen 21 </ b> A at a place where the user of the image forming apparatus 100 can visually recognize. Specifically, the screen 21 </ b> A is provided on the upper side of the display unit 21. The upward direction is an example of a specific direction in the present invention. The display unit 21 receives power supply under the control of the control unit 12 and displays an image based on the reception data from the control unit 12 (see FIG. 3) on the screen 21A.

  The touch panel 22 has a plurality of transparent electrodes provided on a glass substrate. The touch panel 22 is provided on the screen 21A so as to cover the entire area of the screen 21A (see FIG. 5). The touch panel 22 receives power supply under the control of the control unit 12 and outputs an electrical signal corresponding to the operation by the user as an operation signal.

  The attachment portion 23 is provided on the lower side with respect to the display portion 21 in the housing 10 (see FIG. 4). The said downward direction is an example of the reverse direction of the specific direction in this invention. The attachment portion 23 is configured to be capable of attaching a plurality of predetermined card readers 24.

  Each of the plurality of types of card readers 24 has a predetermined outer dimension. Each of the external dimensions may be different for each of the plurality of types of card readers 24. Each of the plurality of types of card readers 24 has a detection area 24B over which an IC card 24A is held by an end user (details will be described later) as a first example of the user (see FIG. 5). Each of the plurality of types of card readers 24 detects the IC card 24A held over its own detection area 24B.

  One of the plural types of card readers 24 is attached to the attachment portion 23 (see FIG. 5). Specifically, the image forming apparatus 100 is delivered to the sales side as a second example of the user of the image forming apparatus 100 with no card reader 24 attached to the attachment portion 23 at the time of factory shipment. The Examples of the sales side include a dealer who has a contract with a manufacturing company of the image forming apparatus 100, or the manufacturing company and its sales company. In addition, a manual that describes how to attach the attachment unit 23 to the attachment portion 23 and the attachment position of each of the plurality of types of card readers 24 is distributed to the sales side. The card reader 24 is attached by the sales side as an optional equipment according to the demand of the end user. More specifically, the sales side presents the plurality of types of card readers 24 to the end user side. On the sales side, the card reader 24 selected by the end user side is attached to the attachment portion 23 according to the manual. The card reader 24 attached on the sales side corresponds to the mounting card reader in the present invention. More specifically, the card reader 24 is attached to the attachment portion 23 so as to be close to the display portion 21 immediately below the display portion 21 (see FIG. 4). Further, the card reader 24 is attached to the attachment portion 23 so that its own detection area 24B and the screen 21A of the display portion 21 overlap in the upward direction. After the card reader 24 is attached, the image forming apparatus 100 is delivered to the end user. Hereinafter, an area of the screen 21A where the detection area 24B and the screen 21A overlap in the upward direction is referred to as an overlap area LA1 (see FIG. 5).

  Here, it is assumed that the plurality of types of card readers 24 are attached to the attachment portion 23. Under this assumption, the detection areas 24B are not necessarily arranged at the same position in the housing 10 (see FIG. 4), and may be arranged at different positions below the display unit 21. Therefore, the position of the overlap area LA1 on the screen 21A may vary depending on the card reader 24 attached to the attachment portion 23.

  The IC card 24A (see FIG. 5) includes a storage unit (not shown) in which user identification data for identifying the end user is stored. In addition to the user identification data, authority data indicating that the end user possessing the IC card 24A is authorized to use the image forming apparatus 100 may be stored in the storage unit.

  The plurality of types of card readers 24 are contactless card readers. Each of the plurality of types of card readers 24 detects the IC card 24A held over its own detection area 24B after the image forming apparatus 100 is installed on the end user side and attached to the mounting portion 23. Thereafter, each of the plurality of types of card readers 24 acquires the user identification data from the IC card 24A and transmits it to the control unit 12 (see FIG. 3). The control unit 12 performs an authentication process for the IC card 24A. Specifically, the control unit 12 determines whether or not the end user is permitted to use the device based on the user identification data (see step S7 in FIG. 4). The self apparatus is the image forming apparatus 100 or the display apparatus.

  The operation input unit 25 is disposed on the right side of the touch panel 22 in the housing 10 (see FIG. 4). The operation input unit 25 includes a plurality of physical buttons such as a start key. The start key is operated by the end user when the image forming apparatus 100 starts reading the document. When the end key is operated by the end user, the start key outputs an electric signal indicating the reading start of the document to the control unit 12 as a reading start signal. In addition, at least one of the plurality of physical buttons is used as a sleep return button 25A. The sleep return button 25A is operated by the end user before the use of the image forming apparatus 100 is started. When operated by the end user, the sleep return button 25A outputs an electrical signal indicating return from the sleep mode to the control unit 12 as a return signal.

  In FIG. 6, the control unit 12 includes a CPU, a nonvolatile memory, a RAM, and the like. The control unit 12 may be an electronic circuit such as an ASIC (Application Specific Integrated Circuit) or a DSP (Digital Signal Processor). The non-volatile memory stores a main program and a setting program. The CPU executes the main program while using the RAM as a work area, and controls the image forming apparatus 100 in an integrated manner. The setting program is called by the sales person operating the operation display unit 11 when the card reader 24 is attached to the attachment part 23 on the sales side. The control unit 12 updates the flag data FD1 in the database DB1 by executing the setting program.

  Specifically, in the control unit 12, the database DB1 is already stored in the nonvolatile memory at the time of factory shipment. The nonvolatile memory corresponds to a storage unit in the present invention. In the database DB1, a set of device identification data DD1, area data RD1, and flag data FD1 is recorded for the plurality of types of card readers 24. In other words, device identification data DD1, area data RD1, and flag data FD1 are recorded in the database DB1 in association with each other.

  The device identification data DD1 is data that can identify each of the plurality of types of card readers 24. Specifically, the device identification data DD1 represents a name and a manufacturer that are assigned to the card reader 24 in advance. In addition, the device identification data DD1 may be an identification number or the like assigned in advance to each of the card readers 24.

  The area data RD1 indicates an overlap area LA1 (see FIG. 5) corresponding to the device identification data DD1 corresponding to itself. More specifically, the area data RD1 is an image (see FIG. 8) showing the inner and outer edges of the corresponding overlap area LA1 as the detection area 24B of the card reader 24 identified by the same set of device identification data DD1. It is image data to represent. More specifically, the area data RD1 includes pixel coordinate values and the like on the screen 21A for specifying the inner and outer edges of the overlap area LA1 and the color values of the pixels. When the image is displayed on the screen 21A in the overlap area LA1 based on the area data RD1 (see FIG. 8), the end user locates the detection area 24B that is provided directly below the display unit 21 and is not visible. Can be recognized.

  The flag data FD1 is data indicating whether or not the card reader 24 identified by the same set of device identification data DD1 is attached to the attachment portion 23. Specifically, since no card reader 24 is attached to the attachment portion 23 at the time of factory shipment, all flag data FD1 is set to off at the time of factory shipment. The flag data FD1 indicates that when the card reader 24 is attached to the attachment part 23 on the sales side attached to the attachment part 23, the control part 12 executes the setting program according to the operation of the person on the sales side. Thus, the same set of flag data FD1 as the device identification data DD1 of the attached card reader 24 is set to ON. In this case, the ON flag data FD1 specifies that the card reader 24 identified by the same set of device identification data DD1 is attached to the attachment portion 23. The flag data FD1 set to ON is an example of first identification information in the present invention.

  Further, the control unit 12 functions as an acquisition processing unit 12A, a display control unit 12B, an authentication processing unit 12C, a function stop unit 12D, a power supply control unit 12E, and an operation reception unit 12F by executing the main program.

  The acquisition processing unit 12A includes region data RD1 corresponding to one card reader 24 (that is, the mounted card reader) attached to the attachment unit 23 among the plurality of region data RD1 stored in the nonvolatile memory. To get. The area data RD1 acquired by the acquisition processing unit 12A corresponds to specific area data in the present invention.

  The display control unit 12B displays an image indicating the detection area 24B of one card reader 24 attached to the attachment unit 23 on the screen 21A in the overlap region LA1 indicated by the region data RD1 acquired by the acquisition processing unit 12A. Let

  Further, when delivered to the end user side, a corresponding card reader 24 (that is, the mounted card reader) is attached to the attachment portion 23 in one of the area data RD1 stored in the nonvolatile memory. Is associated with the flag data FD1 (that is, flag data FD1 set to ON). In this case, the acquisition processing unit 12A acquires the area data RD1 associated with the flag data FD1 set to ON from the database DB1 of the nonvolatile memory.

  When an image representing the overlap area LA1 is displayed on the screen 21A (see FIG. 8), the end user can recognize the location of the detection area 24B over which the IC card 24A is held. The end user holds the IC card 24A over the image representing the overlap area LA1 for authentication or the like. The card reader 24 reads the user identification data from the IC card 24 </ b> A and transmits it to the control unit 12. Thereafter, the control unit 12 functions as an authentication processing unit 12C, and authenticates the IC card 24A based on the received user identification data.

  The function stop unit 12D stops the function of the touch panel 22 from the display of the image until the detection of the IC card 24A held over the image is completed. Specifically, the function stop unit 12D can stop the function of the touch panel 22 by stopping the power supply to the touch panel 22 from the display of the image until the detection is completed. Further, when power is supplied to the touch panel 22 from the display of the image until the detection is completed, the function stop unit 12D receives the operation signal sent from the touch panel 22 during this time. By ignoring, the function of the touch panel 22 can be stopped.

  When the detection of the IC card 24A is completed, the power supply control unit 12E starts power supply to the touch panel 22 and causes the touch panel 22 to function.

  In addition, when the detection of the IC card 24 </ b> A is completed, the operation reception unit 12 </ b> F starts receiving the operation signal sent from the touch panel 22 and causes the touch panel 22 to function. Specifically, when power is supplied to the touch panel 22 before the IC card 24A is detected, the touch panel 22 can transmit the operation signal to the control unit 12 according to the touch operation by the end user. When the detection of the IC card 24 </ b> A is completed, the operation reception unit 12 </ b> F starts specifying the position operated by the end user on the touch panel 22 based on the operation signal. The control unit 12 controls the image forming apparatus 100 based on the position specified by the operation receiving unit 12F.

  Next, the processing of the control unit 12 in the display device and the image forming apparatus 100 according to the present invention will be described more specifically with reference to FIG.

  As described above, on the sales side, one of a plurality of types of card readers 24 is attached to the attachment portion 23 as the attachment card reader. The sales person operates the operation display unit 11 to call the setting program. As a result, the control unit 12 executes the setting program, and displays all the sets of the device identification data DD1 and the flag data FD1 included in the database DB1 on the screen 21A. The sales person operates the touch panel 22 and the like to set the flag data FD1 corresponding to the attached card reader 24 to ON. Based on the operation signal from the touch panel 22 or the like, the control unit 12 updates the corresponding flag data FD1 in the database DB1 to ON. Thereafter, the image forming apparatus 100 is delivered from the sales side to the end user.

  The image forming apparatus 100 is installed on the end user side. After the main power supply (not shown) of the image forming apparatus 100 is turned on, the control unit 12 determines whether or not the image forming apparatus 100 is in the sleep mode (step S1 in FIG. 7). In the sleep state, the control unit 12 restricts power supply to the image forming unit 300, the display unit 21, the card reader 24, and the touch panel 22. In particular, the control unit 12 functions as the function stop unit 12D and stops the function of the touch panel 22. Note that, in the devices included in the image forming apparatus 100, the devices whose power supply is restricted during the sleep state are appropriately determined. For example, power may be supplied to the touch panel 22 or the card reader 24 even during the sleep state.

  If the controller 12 does not determine that it is in the sleep mode (NO in step S1), the process proceeds to step S4. When it determines with the control part 12 having entered into the said sleep mode (it is YES at step S1), a process is advanced to step S2.

  In step S2, the control unit 12 waits for the sleep return button 25A to be operated, and determines whether or not the sleep return button 25A has been operated (step S2). Specifically, the control unit 12 determines whether or not the return signal has been sent from the sleep return button 25A.

  When it is not determined that the return signal has been sent (NO in step S2), the control unit 12 returns the process to step S1. On the other hand, when determining that the return signal has been sent (YES in step S2), the control unit 12 advances the process to step S3.

  In step S3, the control unit 12 functions as the power supply control unit 12E. The control unit 12 starts power supply to the display unit 21 and the card reader 24. Thereby, the control unit 12 causes the display unit 21 and the card reader 24 to function. In other words, the display unit 21 can display an image. The card reader 24 can detect the IC card 24A and read the user identification data from the IC card 24A when the IC card 24A is held over the detection area 24B. The control part 12 advances a process to step S4 after execution of step S3.

  In the present embodiment, power supply to the touch panel 22 is not started in step S3, but is started in step S8. In step S3, power supply to the touch panel 22 may be started. When power supply to the touch panel 22 is started in step S <b> 3, when the end user subsequently presses the touch panel 22, the touch panel 22 transmits the operation signal to the control unit 12. However, the control unit 12 (that is, the function stop unit 12D) completes the authentication of the IC card 24A by the authentication processing unit 12C until it is determined in step S5 that the end user may use its own device. And the operation signal received from the touch panel 22 is ignored. The controller 12 may ignore the operation signal until the IC card 24A is detected.

  In step S4, the control unit 12 functions as the acquisition processing unit 12A, accesses the database DB1 of the non-volatile memory, and sets the region data RD1 (that is, a specific region) that is the same set as the flag data FD1 that is set to ON. Data).

  Next, the control unit 12 functions as the display control unit 12B, and outputs the area data RD1 acquired in step S4 to the display unit 21 (step S5). Based on the area data RD1, the display unit 21 displays an image showing the detection area 24B of the card reader 24 (that is, the mounted card reader) attached to the attachment part 23 in the overlap area LA1 on the screen 21A. One image is displayed (see FIG. 8). Accordingly, the end user can recognize the detection area 24B of the card reader 24 attached to the attachment portion 23. Specifically, even when the plurality of types of card readers 24 can be attached to the attachment portion 23 in the housing 10, the image forming apparatus 100 displays an image based on the area data RD1 on the screen 21A. The end user can easily recognize the place where the IC card 24A is held on the screen 21A.

  After displaying the image in the overlap area LA1, the end user holds the IC card 24A over the image displayed on the screen 21A. The card reader 24 detects the IC card 24A in contact with the image and communicates with the IC card 24A. Thereby, the card reader 24 reads out the user identification data from the storage unit in the IC card 24 </ b> A and transmits it to the control unit 12.

  After step S5, the control unit 12 determines whether or not the user identification data has been sent from the card reader 24 (step S6). If it is not determined that the user identification data has been sent (NO in step S6), the control unit 12 returns the process to step S6. On the other hand, when it is determined that the user identification data has been sent (YES in step S6), the control unit 12 advances the process to step S7.

  In step S7, the control unit 12 functions as an authentication processing unit 12C and performs an authentication process based on the user identification data. Specifically, the authentication processing unit 12C authenticates the IC card 24A held over the screen 21A, and determines whether or not to permit the end user holding the IC card 24A to use the own device. Specifically, in the control unit 12, the authentication processing database (not shown) is stored in the nonvolatile memory in advance before the use of the image forming apparatus 100 is started. The user identification data of the end user who is permitted to use the device is recorded in the authentication processing database. The control unit 12 determines that the end user may use the own device when the user identification data sent in step S3 is recorded in the database for authentication processing. In addition, when the authority data is stored in the storage unit of the IC card 24A, the control unit 12 uses the own device when the end user receives the authority data from the IC card 24A. It is determined to be good.

  When it is not determined that the end user may use the own device (NO in step S7), the control unit 12 displays an image indicating that the end user cannot use the own device on the screen 21A. Thereafter, the process of FIG. 4 is terminated. In addition, the control part 12 may return a process to step S6, when it determines with the said end user not being allowed to use the said own apparatus (it is NO at step S7).

  On the other hand, if the control unit 12 determines that the end user is permitted to use the device (YES in step S7), that is, after the authentication of the IC card 24A is completed, the process proceeds to step S8. Note that power supply to the touch panel 22 may not be started in step S3. That is, the function stop unit 12D may stop the function of the touch panel 22 from the time when the image indicating the detection area 24B is displayed on the screen 21A until the authentication of the IC card 24A is completed. In this case, the control unit 12 functions as the power supply control unit 12E in step S8, starts supplying power to the touch panel 22, and causes the touch panel 22 to function. In the present embodiment, since the touch panel 22 is provided on the upper side with respect to the detection area 24B, the end user may touch the touch panel 22 when holding the IC card 24A over the detection area 24B. However, since the control unit 12 starts supplying power to the touch panel 22 in step S8, the operation signal is not output even if the end user touches the touch panel 22 while holding the IC card 24A over the detection area 24B. Thereby, it can prevent that the operation reception part 12F erroneously detects the position where the touch panel 22 was operated before step S8. Further, the power consumption of the image forming apparatus 100 can be suppressed by delaying the start of power supply to the touch panel 22 as much as possible. The control unit 12 may start supplying power to the touch panel 22 until the IC card 24A is detected.

  In addition, when the power supply to the touch panel 22 is started in step S3, the function stopping unit 12D displays the image indicating the detection area 24B on the screen 21A and completes the authentication of the IC card 24A. During this time, the operation signal received from the touch panel 22 is ignored. In this case, in step S8, the function stop unit 12D may end ignoring the operation signal, and the control unit 12 may further start to function as the operation reception unit 12F. The operation accepting unit 12F starts accepting the operation signal sent from the touch panel 22. Specifically, the operation reception unit 12F starts to specify the position where the end user operates the touch panel 22 based on the operation signal. As described above, the operation receiving unit 12F can start receiving the operation signal in step S8, thereby preventing erroneous detection of the position where the touch panel 22 is operated before step S8.

  After step S8, the end user operates the start button after placing the document on the contact portion 1. When receiving the reading start signal from the start button, the control unit 12 starts control of the image reading unit 200 and the image forming unit 300 (step S9). As a result, the image reading unit 200 generates the document image data. The image forming unit 300 forms a toner image based on the document image data on the image carrier 4 and then discharges the printed matter to the outside of the image forming apparatus 100. The document image data is an example of a second image in the present invention.

  In the embodiment, the flag data FD1 is set to ON when the card reader 24 is attached to the attachment portion 23 on the sales side. However, as shown in FIG. 9, there may be a case where each of the overlap areas LA1 corresponding to the plurality of types of card readers 24 overlaps with each other on the screen 21A. In this case, the flag data FD1 corresponding to the mounted card reader is not set to ON on the sales side, but the image forming apparatus 100 sets the flag data FD1 corresponding to the plurality of types of card readers 24 to ON. You may ship from the said factory in the state made. In this case, it is not necessary to set the flag data FD1 on the sales side. The plurality of flag data FD1 set to ON correspond to the second identification information in the present invention, and specify that the plurality of overlap areas LA1 overlap each other on the screen 21A. Further, the control unit 12 acquires the area data RD1 corresponding to all the flag data FD1 set to ON in Steps S4 and S5 of FIG. 7 from the nonvolatile memory, and in Step S5, all the area data An image indicating the detection areas 24B of the plurality of types of card readers 24 is displayed on the display unit 21 in the overlap area LA1 indicated by RD1 (see FIG. 9). In FIG. 9, broken lines are virtual lines indicating individual overlap areas LA1.

  In the embodiment, the case where the operation display unit 11 as a display device in the present invention is applied to the image forming apparatus 100 has been described. However, the operation display unit 11 may be applied to an electrical device other than the image forming apparatus 100.
