  As described above, in the conventional personal authentication in the image forming apparatus or the like, the operation accepted by the operation unit during the authentication is recognized as being performed by the authenticated user, so that the operation of the authenticated user and other operations are performed. It cannot be recognized separately. For example, an unintended operation (erroneous operation) performed when an object falls on the operation unit or the end of a document contacts, or an operation performed by another user while the authenticated user is temporarily away from the device There is a possibility that (spoofing operation) or the like may be erroneously recognized as being performed by the authenticated user.

  In the technique of Patent Document 1 in which a fingerprint authentication mechanism is incorporated in a switch having a specific function, it is conceivable to prevent the above-described erroneous recognition by incorporating a fingerprint authentication mechanism in all operation members. When the number increases, the mounting layout becomes difficult and the cost increases.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a system configuration example of an image processing system 5 according to an embodiment of the present invention. The image processing system 5 includes a multifunction device 10 as an image processing device (information device device) and a terminal device 40 in which authentication data (identification data) of a user who uses the multifunction device 10 is stored. The multifunction machine 10 is provided with an operation panel 19 at the upper front of the apparatus main body 10a. The user can perform various operations for using the multifunction machine 10 through the operation panel 19.

  The multifunction device 10 optically reads a document image, prints the duplicate image on a recording paper, and outputs it, and stores the scanned document image data as a file or transmits it to an information processing terminal such as a personal computer. A printer function for printing an image related to print data received from the information processing terminal on a recording sheet and outputting it, a facsimile function for transmitting and receiving image data, and the like.

  Furthermore, the multifunction device 10 is linked to the function of performing communication using the terminal device 40 carried by the user and the user's human body as a communication path (human body communication function), and the operation of the operation panel 19 by the user. It has a function of communicating with the terminal device 40 using the human body as a communication path and authenticating a user based on authentication data (user authentication function), and a function of controlling an operation in accordance with the authentication result.

  The authentication data is authentication data used for user authentication. In the present embodiment, the authentication data also has a function as identification data (personal identification information) that can identify a user. Therefore, with respect to the function for controlling the operation for the operation according to the authentication result, the function for communicating with the terminal device 40, identifying the user based on the identification data, and controlling the operation for the operation according to the identification result. It can also be said.

  Human body communication is a communication technology that uses a human body as a communication path to perform short-distance data communication, and there are a plurality of types such as a current method and an electric field method.

  The current method is a method of performing communication by passing a weak current (alternating current) through the human body and putting data (information) on the current. For example, data communication between both devices can be performed by simply touching an electrode of an information equipment device or the like as a communication partner with a hand wearing a wristwatch type terminal device (data transmitter / receiver).

  In the electric field method, an electric field is generated in the vicinity of the human body, the dielectric body is dielectrically polarized, and the entire human body becomes a communication path covering the electric field. The electric field induced in the vicinity of the human body (the surface of the human body) In this method, data communication is performed through a communication path, and an electric field is used as a data signal medium. Specifically, a voltage (AC voltage) is applied to the surface of the human body by an electrode of the terminal device to generate a weak electric field (induction), the electric field spreads to the human body surface, and the human body surface is close to the electrode of the information equipment device Alternatively, the contact is induced by an electric field to generate a potential at the electrode. This is a mechanism for performing data communication by detecting a change in potential generated in the electrode induced by the fluctuation of the electric field (change in electric field strength) with an optical electric field sensor and converting it into an electric signal.

  In the electric field method, fluctuations in the electric field are detected as a signal, so there is no need for the human body to be in direct contact with a communication device such as a terminal device or an information device, and communication is possible even if an insulator exists between the signal paths. To establish. For example, communication is possible not only in the part where the hand (finger) or foot is in contact, but also within a range of several centimeters from the surface of the human body, and communication is possible even if clothes or shoes are interposed between the human body.

  The terminal device can be configured in various shapes that can be carried by the user, such as a card type, a wristwatch type, and a key type. For example, in the case of a card type incorporated in an employee ID card, as shown in FIG. 1, the user attaches the card type terminal device 40 to a neck strap 48 and hangs it on the neck or puts it on a pocket of clothes. You can carry it with you. When configured as a wristwatch, it can be worn on the wrist and carried.

  Further, since human body communication technology can supply power to the terminal device through the human body, it is not necessary to mount a secondary battery such as a battery in the terminal device, and it is possible to configure a terminal device that is easy to downsize and excellent in portability. it can.

  FIG. 2 is an exploded perspective view showing the configuration of the operation panel 19 in the multifunction machine 10. Here, an example of a configuration corresponding to electric field type human body communication will be described.

  The operation panel 19 includes a panel body 30, an electrode sheet 36, and an insulating cover 38. The electrode sheet 36 and the insulating cover 38 are attached so as to be overlapped and adhered in that order so as to cover the upper surface (surface) 30 a of the panel body 30, and constitute the upper surface portion of the operation panel 19. It has become.

  The panel body 30 is provided with a touch panel 31 that is an operation member, a plurality of operation buttons 32 to 34, and an optical electric field sensor 35 on a horizontally long rectangular upper surface 30 a. The touch panel 31 is a position input device that is provided on the surface (on the screen) of a display unit configured by a liquid crystal display or the like and detects a pressed coordinate position. The touch panel 31 has a horizontally long rectangular shape that is smaller than the upper surface 30 a of the panel main body 30, and is disposed at the approximate center of the upper surface 30 a of the panel main body 30. The plurality of operation buttons are a mode selection button, a start button 32, a stop button 33, a numeric keypad 34, and the like, and are arranged, for example, in the right region (the right side of the touch panel 31) on the upper surface 30a of the panel body 30.

  The electrode sheet 36 functions as an antenna for performing electric field type human body communication. The electrode sheet 36 is made of a conductive material, and has a horizontally long rectangular shape that is the same as or substantially the same size as the upper surface 30 a of the panel body 30. Openings 37 for exposing those operation members on the operation panel are formed at locations corresponding to the touch panel 31 and the operation buttons 32 to 34 in the electrode sheet 36. On the upper surface (front surface) of the electrode sheet 36, for example, an operation guide in which characters and symbols are used to describe the names and functions of the operation buttons and the operation of the touch panel 31 is printed. The electrode sheet 36 also has a function of displaying an operation guide, and has a configuration also used as an operation guide sheet.

  When the electrode sheet 36 is attached to the upper surface 30 a of the panel body 30, the upper surface 30 a is covered with the electrode sheet 36 and the operation member is exposed from the opening 37. Accordingly, the electrode sheet 36 is arranged around the operation member. In addition, although the electrode sheet 36 of this example is arrange | positioned so that the operation member may be surrounded, you may make it arrange | position around the operation member without surrounding. For example, it is good also as a structure which arrange | positions an electrode sheet with respect to the touch panel 31 in the left-right and lower peripheral places except the upper side.

  The insulating cover 38 is formed of an insulating material such as synthetic resin (plastic). As with the electrode sheet 36, the insulating cover 38 has a horizontally long rectangular shape that is the same as or substantially the same size as the upper surface 30 a of the panel body 30, and each location corresponding to the touch panel 31 and the operation buttons 32 to 34. An opening 39 is formed in the opening. Further, at least a portion corresponding to the operation guide of the electrode sheet 36 is formed to have light transmittance. For example, the entire portion is formed of a light-transmitting synthetic resin material, or even if the material is colored by applying a decorative coating or the like, the portion is formed so as to remain light-transmitting without being colored. It can be set as a structure.

  When the insulating cover 38 is attached to the electrode sheet 36 on the panel main body 30 in an overlapping manner, the electrode sheet 36 is covered with the insulating cover 38 and the operation member is exposed from the opening 39. Thereby, it becomes the structure by which the visibility and operability of the operation member were ensured.

  The optical electric field sensor 35 functions as a communication unit (reception unit) for performing electric field type human body communication. For example, the optical electric field sensor 35 is located at the front of the touch panel 31 (front side of the touch panel 31). ) Etc. The optical electric field sensor 35 can be connected to the electrode sheet 36. Specifically, the optical electric field sensor 35 can be connected to the panel body 30 as long as the electric field sensor 35 can be connected so that the electric potential induced in the electrode sheet 36 can be detected. It can be placed at any position.

  The optical electric field sensor 35 includes, for example, an electro-optic crystal (electro-optic crystal), a laser light source, a polarizing plate, a photodetector, and the like. An electro-optic crystal is an optical element having an electro-optic effect in which an optical property (refractive index) changes according to a change in potential. The electro-optic crystal is, for example, partly connected to the electrode sheet 36 and any part other than the connection part is connected to the GND (ground) of the multi-function device 10. A generated potential (potential change) is applied.

  The connection with the electrode sheet 36 may be, for example, a configuration in which the upper surface portion of the optical electric field sensor 35 is exposed from the upper surface 30a of the panel main body 30 and directly connected to the electrode sheet 36, or is generated in the electrode sheet 36. A configuration may be adopted in which a part (connecting portion) is arranged (closely arranged) at a distance where the potential to be detected can be detected. However, in order to detect a weak potential with high accuracy, it is preferable that the optical electric field sensor 35 is connected to the electrode sheet 36 to be connected.

  The optical electric field sensor 35 irradiates the electro-optic crystal with laser light from a laser light source, converts the laser light transmitted through the electro-optic crystal into a predetermined polarized light with a polarizing plate, and detects the light intensity with a photodetector. By converting to an electric signal, the electric signal is extracted from a potential change induced in the electrode sheet 36 and applied to the electro-optic crystal by being induced by an electric field.

  In electric field type human body communication, as described above, communication is possible even if an insulator is present between signal paths, and communication is possible within a range of several centimeters from the human body surface. When operating (pressing) 32 to 34, communication can be performed only by approaching without touching the electrode sheet 36 directly by a hand or a finger.

  Further, in this example, the electrode sheet 36 is disposed around (around) the operation member, but may be disposed so as to cover the operation member. For example, it is possible to form an electrode sheet that can ensure the visibility and operability of the coated operation member by using an elastic material having conductivity and light transmittance such as conductive plastic.

  Such an electrode sheet can be applied to a current method in which communication is possible by directly touching an electrode (antenna). In the case of the current method, the terminal device 40 is preferably a wristwatch type that is carried (attached) in direct contact with the human body.

The user is identified (specified) and authenticated by an authentication process such as comparing (step S102). If the authentication is impossible (step S103; NO), the CPU 11 does not allow the user to use the multifunction machine 10, and ends this operation with an error (End).

  In the case of authentication permission (step S103; Yes), the CPU 11 permits the use of the multifunction device 10 to this user. Then, the user information is stored in the RAM 16 (step S104), a screen tailored to the user is displayed on the display unit 18 (step S105), and the multifunction device 10 is put into a waiting state for the next operation.

  The stored user information is, for example, a management table for managing (recognizing) an authenticated user and operations related to the user's operation. For example, when the user is authenticated, a management table is created in the RAM 16, user identification information (such as a user ID), information indicating operation details (such as screen transition information, job type information, and job setting information), a job The information indicating the status (during setting, editing work, executing, etc.) is associated and stored in the management table. This management table is stored at least until the job is canceled or executed in response to an execution instruction operation from the user, and then automatically deleted.

  By this management table, the management of the authenticated user and the operation related to the operation of the user, for example, the display of the screen corresponding to the operation button that has detected the touch operation, the job type selection, the setting, the cancellation, the execution (start and end), Operations such as standby, interruption, and operation acceptance refusal are managed.

  The screen to be displayed is switched according to the operation received from the user. For example, a screen corresponding to a pressed mode selection button (hard button) or a screen corresponding to an operation button touched among various operation buttons (soft buttons) displayed on the display unit. .

  Subsequently, when a touch operation on the operation member of the operation panel 19 is received (step S106), the user is identified by the authentication process similar to step S102 based on the authentication data input to the external terminal communication unit 24 with the touch operation. And authentication is performed (step S107). The CPU 11 compares the user identified here, that is, the user who performed the new operation with the user indicated by the information (user identification information etc.) stored in step S104, that is, the user who performed the previous operation, If they are the same user (step S108; Yes), an operation (process) corresponding to the operation is performed (step S109). If the operation is not completed by the current operation (step S110; No), the process returns to step S106 to wait for the next operation.

  If the user who performed the new operation is not the same as the user who performed the previous operation (step S108; No), the setting content is reset by deleting the management table of the previous user (step S111). ), The process returns to step S103. If the user who has performed a new operation cannot be authenticated (step S103; NO), the CPU 11 does not allow the user to use the multifunction machine 10 and ends with an error (End). In the case of authentication permission (step S103; Yes), the CPU 11 permits the use of the multifunction device 10 to this user, and similarly performs step S104 and subsequent steps. In this case, a new authentication user management table different from the authentication user who performed the previous operation is created, and operations related to the user's operation are managed.

  When the operation is completed in step S110 (step S110; Yes), this operation is ended (End).

  If authentication data is not input in the touch operation on the operation member in step S106, it is determined that an article or the like is in contact with the operation member, and the next operation waiting state is performed without performing an operation (processing) for the operation. You may make it.

  As described above, in the MFP 10 according to the present embodiment, a user who uses the MFP 10 by operating the operation panel 19 provided with a plurality of operation members is authenticated by performing data communication using human body communication ( The terminal device of the user who operates the operation member of the operation panel 19 with a simple configuration simply by disposing the electrode sheet 36 on the surface of the operation panel 19 as an interface with the user for performing authentication. The user can be authenticated by performing data communication with human body 40 through human body communication.

  In particular, in the case of using electric field type human body communication, the electrode sheet 36 is simply configured by combining an electric field sensor (optical electric field sensor 35) with the electrode sheet 36, and is induced by an electric field on the human body surface close to the electrode sheet 36. Data for authenticating the user (authentication data) can be extracted as an electrical signal from the potential change generated in the sheet 36 to authenticate the user.

  Specifically, when a user's finger or hand approaches the electrode sheet 36 on the operation panel 19 when operating the operation member, the electrode sheet 36 causes the external terminal communication unit 24 (optical electric field sensor 35) and the terminal device 40 to be connected. A communication path including the user's human body is formed between them, and the user authentication data can be received from the user terminal device 40 through the communication path to authenticate the user. And with such a simple configuration, it becomes possible to distinguish and recognize an operation by an authenticated user and other operations, for example, an operation by another user or an erroneous operation caused by an article touching an operation member, It is possible to prevent erroneous recognition of operations. Further, in the present embodiment, since the electrode sheet 36 is also used as the operation guide sheet, it can be configured at a lower cost than the case where they are provided individually, and the operation panel 19 can be easily assembled.

  Further, in the multi-function device 10, user authentication is performed in conjunction with detection of an operation (touch operation) on the operation panel 19 without performing a separate authentication operation such as password authentication, card authentication, or biometric information authentication such as fingerprint or vein. (Authentication processing) is performed, and user identification and authentication are performed. The multifunction device 10 controls the operation for the operation according to the authentication result (identification result).

  For example, as described with reference to FIG. 5, when authentication is not possible, the operation according to the operation is not performed (operation is not accepted), and when authentication is permitted, the operation according to the operation is performed (operation is accepted). Depending on whether or not the user matches between the operation and the operation of the new operation, that is, whether or not the same user is continuing the operation / whether the user has been replaced It is possible to control operations. Further, a user who performs a new operation can be identified (recognized) without once ending the operation being managed, and the operation for the operation can be controlled.

  Thereby, it is possible to perform an operation corresponding to the user of the received operation without performing a special operation and switching the user authentication state (recognition state) between the operations. In user authentication, special operations related to authentication (such as authentication operations and deauthentication operations) are not required, and operations other than authenticated users are not accepted, and operations are switched for each authenticated user. (Authentication status linked to operation detection and automatic switching of operations). Thereby, while improving the operability and security in user authentication, the operation corresponding to the user of the received operation can be performed, thereby improving convenience.

  In particular, when the user changes during the management of the operation related to the job setting as described in FIG. 5, the setting of the job under management related to the user before the change is invalidated and the operation related to the new user is changed. It is switched and management of the new operation is started. In such user switching, the operability for a new user can be improved while ensuring the security of the operation managed before the switching.

(Example of electrode arrangement)
FIG. 6 shows a configuration example when an electrode sheet having a function as an antenna in human body communication is arranged around the multifunction peripheral.

  The multi-function device 50 of this example is provided with an operation panel 51 on the right side in the upper front portion of the apparatus main body 50a. Similar to the operation panel 19 described in FIG. 2, the operation panel 51 is provided with a plurality of operation members such as a touch panel and various operation buttons. However, the operation panel 51 is not provided with the electrode sheet and the optical electric field sensor described in FIG. 2, and the optical electric field sensor 52 is provided in the lower part of the apparatus main body 50a. The multi-function device 50 further includes two electrode sheets 53 and 54 and a conductive cable 55 connected thereto.

  One electrode sheet 53 is embedded under a carpet or floor material (floor panel) in an installation area 56 where the multi-function device 50 is installed. In this example, the electrode sheet 53 is disposed in a left region in a rectangular installation area 56 that is slightly larger than the bottom surface of the multi-function device 50 (device main body 50a). A right region in the installation area 56 is a GND area 57 to which a flooring or the like is grounded, and the electrode sheet 53 is insulated from the GND area 57.

  The multi-function device 50 is installed in the installation area 56 with the right leg grounded on the floor of the GND area 57 and the left leg grounded on the floor where the electrode sheet 53 is embedded. 52 is disposed close to the electrode sheet 53.

  The optical electric field sensor 52 functions as a communication unit (reception unit) for performing electric field type human body communication in the same manner as the above-described multifunction machine 10. In this example, the optical electric field sensor 52 is connected to the device from the electrode sheet 53 via the legs. It fulfills the function of extracting an electrical signal from the potential change of the electric field propagating to the main body 50a. The optical electric field sensor 52 can be disposed at an arbitrary position in the apparatus main body 50a. However, in order to accurately detect the weak potential of the electric field propagating from the electrode sheet 53 to the apparatus main body 50a via the legs (plastic casters or the like), the vicinity of the legs (in the case of this example, the electrode sheet 53 is applied). It is preferable to arrange it in the vicinity of the adjacent left leg).

  The electrode sheet 53 is desirably disposed at a position corresponding to the leg (position close to the leg). The electrode sheet 53 of this example has a size and arrangement including a position corresponding to the leg, and is configured to efficiently propagate the electric field to the leg while suppressing the propagation loss of the electric field.

  The other electrode sheet 54 connected to the electrode sheet 53 with the conductive cable 55 is embedded under the floor (under the carpet, flooring, etc.) in the authentication area 58 of the multi-function device 50. Similarly, the conductive cable 55 is buried under the floor between the electrode sheet 53 and the electrode sheet 54.

  The authentication area is an area including a position where the user stands when operating the operation panel 51 of the multi-function device 50. For example, an area having a predetermined size (for example, a size on which both feet can ride while one person is standing) including a position separated from the operation panel 51 of the multi-function device 50 by a predetermined distance (for example, several tens of centimeters). Etc. are regarded as authentication areas. The electrode sheet 54 is disposed in the authentication area 58. In this example, the electrode sheet 54 is approximately the same size as the authentication area 58. The periphery of the authentication area 58 where the electrode sheet 54 is disposed is a GND area 59 to which a flooring or the like is grounded. The electrode sheet 54 is insulated from the GND area 59.

  When the multifunction device 50 receives an operation (touch operation) on the operation member of the operation panel 51, the multifunction device 50 performs a control operation similar to the control operation described in FIG. That is, every time an operation is received, an authentication process (steps S102 / S107) is performed, and the operation for the operation is controlled according to the authentication result (user identification result).

  In the configuration of this example, the user can be identified and authenticated only by standing in the authentication area 58. In other words, in addition to the user who is operating the operation panel 51, the user involved in the operation can be identified and authenticated, including the user who wants to operate the operation panel 51 and the like. Whether the user authentication (authentication process) is performed in conjunction with the detection of the operation or not in conjunction with the detection of the operation. For example, after detection of the user in the authentication area 58 (after the user authentication), always or predetermined For example, the authentication process may be performed at time intervals so that the setting can be changed as necessary.

  Thereby, in the multi-function device 50 of this example, when the user carrying the terminal device 40 stands in front of the operation panel 51 in order to use the multi-function device 50, the sole (sole) located in the authentication area 58. Then, the floor on the electrode sheet 54 is stepped on so that the soles of the feet are placed close to the electrode sheet 54. And between the optical electric field sensor 52 and the terminal device 40 by the electrode sheet 54 and the electrode sheet 53 connected to the electrode sheet 54 by the conductive cable 55 and disposed in the vicinity of the optical electric field sensor 52 of the multi-function device 50. A communication path including the user's human body is formed, and the multi-function device 50 can receive the user authentication data from the user terminal device 40 through the communication path, and can identify and authenticate the user.

  As described above, in the multi-function device 50 of the present example, the electrode sheet 54 is disposed in the predetermined authentication area 58 around the apparatus main body 50a. Specifically, the electrode sheet is placed at a position where the user stands when operating the operation panel 51. The user can be identified and authenticated by performing data communication by human body communication with the terminal device 40 of the user who operates the operation panel 51 with a simple configuration in which only 54 is arranged.

  In addition, the optical electric field sensor 52 provided in the apparatus main body 50a of the multi-function device 50 is not directly connected to the conductive cable 55, but is connected to be communicable via the electrode sheet 53 embedded under the floor or the like. The cable 55 can also be buried under the floor. As a result, when the multi-function device 50 (device main body 50a) is moved, damage to the conductive cable 55 caused by accidentally stepping on or hooking the conductive cable 55 can be prevented.

  It is also possible to prevent theft of the multi-function device 50 using this configuration. For example, a crime prevention system that communicates with the optical electric field sensor 52 at regular time intervals or the like is connected to the electrode sheet 53, and communication with the optical electric field sensor 52 becomes impossible as the multifunction device 50 moves. It is possible to prevent the multifunction device 50 from being stolen by a configuration such as notifying a security company when the security system detects it.

  In this example, an electrode sheet 54 disposed at a position close to the human body (the sole of the foot) of the user who operates the multi-function device 50, and an optical electric field sensor 52 provided on the device main body 50a of the multi-function device 50 are provided. As described above, the conductive cable 55 and the electrode sheet 53 disposed in the installation area 56 are connected to be communicable, but the electrode sheet 54 and the optical electric field sensor 52 are directly connected by the conductive cable 55. May be. For example, a configuration may be adopted in which a connector is provided at the tip of the conductive cable 55 so as to be detachably connected to the optical electric field sensor 52.

(Control action example for interrupt operation)
FIG. 7 shows a control operation for an interrupt operation by the multifunction device 10 or the multifunction device 50 described above. The interrupt operation is, for example, an operation of temporarily interrupting a print job of a file stored in the multifunction peripheral or executing a copy job of an original and interrupting another print job or copy job. Here, a case will be described where user A performs an interrupt operation during user B's job execution.

  Whether to accept an interrupt operation, that is, whether to give priority to a preceding job or an interrupt job, is determined based on a comparison result obtained by comparing priorities determined in advance for the user. ing. If the priorities are the same, priority is given to the preceding job. The priority is determined based on, for example, user attributes such as job title and affiliation (department, group, etc.), or authority determined for each user. Here, a case where authority is used as the priority will be described as an example.

  Further, both the multifunction device 10 and the multifunction device 50 can operate in the same manner, but here, the multifunction device 10 will be described as an example.

  As the multifunction device 10 (or the multifunction device 50) receives a touch operation on the operation panel 19 (touch operation on the operation member of the operation panel 19) from the user (step S121), the terminal device 40 carried by the user. Authentication data is received through a communication path including the user's human body, and an authentication process based on the authentication data is performed (step S122). If the authentication is not possible (step S123; NO), the multifunction machine 10 ends this operation without permitting the user to use (End).

  In the case of authentication permission (step S123; Yes), for example, when the user B is authenticated here, the multifunction machine 10 permits the use to the user B. Subsequently, the multifunction machine 10 stores user B information, for example, a management table for managing operations related to user B operations (step S124), and a screen tailored to user B, for example, a job setting screen, etc. Is displayed on the display unit 18 (step S125).

  Upon receiving a job setting and execution operation (pressing the start button 32) from the user B, the multifunction machine 10 executes the job (step S126). The multifunction device 10 monitors whether a user other than the user B receives a touch operation on the operation panel 19 during the execution of this job (step S127), and does not receive the touch operation (step S127; No). When the job of B is finished (step S128; Yes), this operation is finished (End).

  When the above touch operation is received (step S127; Yes) before the job of user B is terminated (step S128; No), for example, when the touch operation is received from user A here, the multifunction machine 10 Stores information about user A, for example, a management table for managing operations related to user A's operation (step S129), and checks whether the job of user B is still being executed (step S130). ). For example, when the job of the user B is completed immediately after the touch operation by the user A (step S130; No), the process proceeds to step S133.

  If the job of user B is being executed (step S130; Yes), the multi-function device 10 compares the authority of user A with the authority of user B (step S131). When the authority of the user A is the same as or lower than the authority of the user B (step S131; No), the process returns to the step S127 without performing processing (control) according to the touch operation of the user A.

  When the authority of the user A is higher than the authority of the user B (step S131; Yes), the multifunction peripheral 10 recognizes that the interrupt control is performed by the user A, and switches from the control of the user B to the control of the user A. Specifically, the job of user B is interrupted (step S132), and a screen tailored to user A, for example, a job setting screen or an appropriate interrupt screen is displayed on the display unit 18 (step S133). Upon receiving a job setting and execution operation from user A (interrupt execution instruction operation by pressing the start button 32), the multi-function device 10 executes the job (step S134) and monitors the end of the job (step S134). Step S135; No).

  When the job of user A is completed (step S135; Yes), it is confirmed whether there is a suspended job (step S136). If there is an interrupted job (step S136; Yes), for example, if the user B's job is interrupted, the multi-function device 10 restarts the user B's job (step S137) and goes to step S127. Return. If there is no interrupted job (step S136; No), this operation is terminated (End).

  The preceding job suspension control by the interrupt operation may be performed at the timing of the interrupt job execution instruction operation (depressing the start button 32).

  As described above, in the MFP 10 or the MFP 50, user authentication using human body communication is performed every time the user touches the operation panel 19, and the user is based on the authentication data received from the terminal device 40 carried by the user. When the authenticated user (user A) related to the newly received operation does not match the user (user B) related to the operation being managed, as in the control operation for the interrupt operation according to the present example That is, when a new authenticated user changes with respect to a user related to the operation being managed, the operation related to one user can be preferentially executed based on the result of comparing the priorities of both users. For example, a plurality of competing operations can be automatically switched based on the priority of the user.

  Specifically, as described above, interrupting an ongoing job related to a low-priority user and interrupting control to perform a job related to a new authenticated user with a high priority first, or to a user with a high priority. Such a running job can be continued, and standby control for waiting a job related to a new authenticated user with a low priority can be automatically performed.

  For example, when another user wants to perform an interrupt copy or the like during a copy or print operation (during job execution) by a certain user, an operation of pressing a specific button such as an “interrupt copy” button is generally required. However, in this example, user authentication is performed when the touch panel or the operation button on the operation panel is pressed, and it is possible to recognize whether the operation is performed by a user other than the user who is currently copying or printing. By recognizing that it is an “interrupt operation” only by a touch operation on the operation panel, it is possible to immediately transition to an appropriate interrupt screen or the like.

  In this way, each time the user touches the operation panel 19, user authentication using human body communication is performed to identify the user, and one of the operation being managed and the operation for the new operation is based on the priority of the user. Since priority execution can be performed automatically, operability and convenience are improved.

(Multiple operation unit configuration example 1)
FIG. 8 shows a configuration example in the case where a plurality of operation panels each having an electrode sheet having a function as an antenna in human body communication are arranged on the surface thereof are provided in the multifunction peripheral.

  In the multifunction machine 10 that performs user authentication using human body communication with the operation on the operation panel described above, the user can be identified for each operation. For example, for each operation received at the same timing on a plurality of operation panels. On the other hand, when each user is authenticated to identify each user and each operation (process) for each operation can be executed in parallel (no conflict), it is also possible to execute each operation in parallel. become. In this example, the MFP performs individual user authentication (individual authentication / parallel authentication) for such simultaneous operation (parallel operation) using a plurality of operation panels, and simultaneously controls a plurality of operations that can be executed in parallel (parallel control). The structure to perform is demonstrated.

  The multi-function device 60 of the present example is arranged apart from the apparatus main body 60a and is directly attached to the apparatus main body 60a, and is configured as a main body operation section. Two operation panels (operation units) with a small second operation panel 64 are provided. The multi-function device 60 also has a function of accepting simultaneous operations on these two operation panels, a function of performing individual authentication for the simultaneous operations, and a function of performing simultaneous control of each operation when the operations for the simultaneous operation can be executed in parallel. It has.

  The first operation panel 62 is provided with a touch panel as an operation member on the surface of the panel body. This touch panel is provided on the surface (on the screen) of a display unit composed of a large liquid crystal display or the like that is slightly smaller than the surface of the panel body. Further, a frame-shaped (frame-shaped) electrode sheet is disposed around the touch panel on the surface of the panel body, and this electrode sheet is covered with an insulating cover or the like as in the operation panel 19 of FIG. The panel body is also provided with an optical electric field sensor connected to the electrode sheet.

  The first operation panel 62 is supported via a support arm 65 attached to the apparatus main body 60 a of the multi-function device 60. For example, as shown in the drawing, the support arm 65 is attached to the right side of the upper back of the apparatus main body 60a, and the first operation panel 62 is supported by the support arm 65 and arranged at the upper right on the rear side of the apparatus main body 60a. Has been. Further, the first operation panel 62 has a function of receiving various operations for previewing various files stored in the multi-function device 60, editing the preview-displayed files, saving and printing the files, and the like. It has.

  The second operation panel 64 is provided with a touch panel as an operation member and a plurality of operation buttons on the surface of the panel body. In the second operation panel 64, a touch panel is provided on the surface (on the screen) of the display unit configured by a small liquid crystal display or the like. The plurality of operation buttons are a mode selection button, a start button, a stop button, a numeric keypad, and the like. Further, an electrode sheet is disposed around the operation member on the surface of the panel body, and this electrode sheet is covered with an insulating cover or the like as in the operation panel 19 of FIG. The panel body is also provided with an optical electric field sensor connected to the electrode sheet.

  The second operation panel 64 is disposed on the right side in the upper front portion of the apparatus main body 60 a in the multi-function device 60.

  FIG. 9 is a block diagram illustrating a schematic configuration of the multi-function device 60. 3, the display unit 18 is replaced with a first display unit 61 and a second display unit 63, and the operation unit 19 (operation panel 19) is replaced with a first operation unit. 62 (first operation panel 62) and second operation unit 64 (second operation panel). The other parts have the same configuration as the parts with the same reference numerals in the multifunction machine 10.

  As described above, the multi-function device 60 of this example includes two operation panels and can simultaneously identify and authenticate users who operate the respective operation panels. It is possible to accept operations and control each operation for each operation simultaneously. For example, the first operation panel 62 accepts a preview display or editing operation of a document file or an image file stored in the multi-function device 60 from one user, and the second operation panel 64 receives a copy or facsimile transmission from the other user. The operation can be received and each operation can be controlled simultaneously. Thus, simultaneous operation (parallel operation) by a plurality (two) of users can be performed, so that the operation efficiency and convenience are improved.

(Multiple operation unit configuration example 2)
FIG. 10 shows a configuration example when a plurality of large operation panels (external operation units) described in FIG.

  The multi-function device 70 of this example has two operation panels having the same configuration as the above-described first operation panel 62 configured as an external operation unit, specifically, a first operation panel (first operation unit) 72 and a second operation panel. A panel (second operation unit) 74 is provided, and an operation panel is not provided on the upper front surface of the apparatus main body 70a. Similarly to the above-described multi-function device 60, the multi-function device 70 has a function of accepting simultaneous operations on the above two operation panels, a function of performing individual authentication for simultaneous operations, and a case where each operation for simultaneous operations can be executed in parallel. Has a function to perform simultaneous control of each operation.

  As described with reference to FIG. 8, the first operation panel 72 is supported by the support arm 75 attached to the right side of the upper part of the back surface of the apparatus main body 70 a and is disposed on the upper right side on the rear side of the apparatus main body 70 a. As shown in FIG. 10, the second operation panel 74 is supported by a support arm 76 attached to the left side of the upper part of the back surface of the apparatus main body 70a and is arranged on the upper left side on the rear side of the apparatus main body 70a.

  As described above, in the MFP 70 of the present example, the two operation panels are spaced apart from each other on the left and right sides, so that two users can operate separately. Thereby, the operability when two users perform simultaneous operation (parallel operation) on these two operation panels is improved.

(Multiple operation unit configuration example 3)
FIG. 11 shows a configuration example when the large operation panel described in FIG. 8 is wirelessly connected to the multifunction machine.

  The multi-function device 80 of this example includes a large first operation panel (first operation unit / wireless operation unit) 82 that is separated from the apparatus main body 80a and wirelessly connected to the apparatus main body 80a, and an upper front portion of the apparatus main body 80a. And a second operation panel (second operation unit / main body operation unit) 84 provided in the apparatus. Further, like the above-described multi-function devices 60 and 70, the multi-function device 80 can execute in parallel the function of accepting simultaneous operations with these two operation panels, the function of performing individual authentication for simultaneous operations, and the operations for simultaneous operations. In some cases, it has a function of performing simultaneous control of each operation.

  The apparatus main body 80a is provided with an operation panel wireless communication unit 85, and the first operation panel 82 includes a main body wireless communication unit 86 that performs wireless communication with the operation panel wireless communication unit 85. Note that FIG. 11 shows only the antenna portion in these wireless communication units.

  The second operation panel 84 has, for example, the same configuration as the operation panel 19 described in FIG. In addition, the operation panel on the apparatus main body 80a side may be configured by the second operation panel 64 described with reference to FIG.

  As described above, in the multi-function device 80 of this example, one of the two operation panels is wirelessly connected to the apparatus main body 80a, so that two users can be connected as in the multi-function device 70 described in FIG. It becomes possible to operate remotely, and the operability when performing simultaneous operation (parallel operation) with these two operation panels is improved. In particular, in this example, the first operation panel 82 can be operated without selecting a location within a communicable range with the apparatus main body 80a, so that convenience is improved.

  Although the case where the number of operation panels is two has been described in FIGS. 8 to 11, three or more operation panels may be used. The MFP is capable of accepting simultaneous operations on these three or more operation panels, performing individual authentication for these simultaneous operations, and executing two or more operations in parallel for each of these simultaneous operations. If possible, it may be configured to have a function of performing simultaneous control of the operations. The operation panel provided in the apparatus main body may be a simple operation panel without a touch panel and a display unit. Moreover, you may comprise so that all the operation panels may be connected with an apparatus main body by radio | wireless, without providing an operation panel in an apparatus main body.

  As a specific example of the simultaneous operation using three or more operation panels described above, a plurality of operation panels (large operation panels) that are externally or wirelessly connected by performing an operation with a scanning operation or a printing operation on the operation panel of the apparatus main body. In this case, an operation that does not involve a scanning operation or a printing operation, for example, a preview display or editing operation of a document file stored in the multifunction device is performed at the same time. As a result, particularly in a large-scale office where the number of users allocated to each multifunction device is large, the operation rate of the multifunction device is increased and productivity (processing efficiency) can be improved.

(Control operation example for multiple operation unit / multiple user individual authentication / simultaneous operation)
12 to 14 show control operations for individual authentication and simultaneous operation by a plurality of users in the multi-function devices 60, 70, 80, etc., having the plurality of operation units (operation panels) in the above example. Here, a case will be described where user A performs a print operation through preview display and editing of a document file stored in the multifunction peripheral in the first operation unit, and user B performs a copy operation in the second operation unit. .

  In addition, in each operation by these two types of simultaneous operations, the print output operation cannot be executed in parallel (exclusive control). Which one is prioritized is the same as the control operation for the interrupt operation described in FIG. The priority (authority) determined in advance for the user is compared and determined based on the comparison result. If the priority is the same, the preceding job is prioritized.

  In addition, all the multifunction devices 60, 70, and 80 can operate in the same manner, but here, the multifunction device 60 will be described as an example.

  The multi-function device 60 (or multi-function devices 70 and 80) receives a touch operation (touch operation on the touch panel) from the user to the first operation unit 62 (step S141), from the terminal device 40 carried by the user. Authentication data is received through a communication path including the user's human body, and authentication processing based on the authentication data is performed (step S142). When the authentication is impossible (step S143; NO), the multi-function device 60 ends this operation without permitting the use of this user (End).

  In the case of authentication permission (step S143; Yes), for example, when the user A is authenticated here, the multi-function device 60 permits the use for the user A. Subsequently, the multi-function device 60 stores information on the user A (operation / management table for the user A, etc.) (step S144), and a screen (preview display / edit screen, etc.) tailored to the user A is displayed on the first display unit 61. (Step S145), the first operation unit 62 receives various operations from the user A, here, preview display and editing of the document file stored in the multi-function device 60 (step S146).

  The multi-function device 60 monitors whether or not the user A receives a touch operation on the second operation unit 64 while receiving the operation on the first operation unit 62 (step S147), and receives the touch operation. If not (step S147; No), if the first operation unit 62 receives a job execution operation from the user A, here a document file print instruction operation (step S148; Yes), the multi-function device 60 executes the job (step S148; Yes). Step S149), this operation is finished (End).

  When a touch operation by a user other than the user A is received while receiving an operation by the user A (step S147; Yes), for example, when a touch operation from the user B to the second operation unit 64 is received here, The multi-function device 60 stores user B information (such as an operation / management table for user B) (step S150), and compares the authority of user B with the authority of user A (step S151). When the authority of the user B is the same as or lower than the authority of the user A (step S151; No), the process proceeds to step S152 in FIG. When the authority of the user B is higher than the authority of the user A (step S151; Yes), the process proceeds to step S163 in FIG.

  In step S152 of FIG. 13, the multi-function device 60 displays a screen (such as a copy setting screen) tailored to the user B on the second display unit 63 (step S152), and the second operation unit 64 performs various operations from the user B. Here, various setting operations relating to copying are received (steps S153 to S154; No). Subsequently, when the multifunction device 60 receives a job execution operation (copy instruction operation by pressing the start button) from the user B via the second operation unit 64 (step S154; Yes), the user A's job (document file print job) ) Is executed (step S155; Yes), the job instructed by the user B is waited (step S156), and the job of the user B that has been kept waiting is executed after the execution of the job of the user A is completed. (Step S157), and this operation is terminated (End).

  When the user A job is not executed (step S155; No), the multi-function device 60 starts the job instructed by the user B (step S158), and performs the first operation during the execution of the user B job. The unit 62 monitors whether or not a job execution operation is received from the user A (step S159; No to step S162; No). Then, without receiving the operation from the user A (step S159; No), when the job of the user B is finished (step S162; Yes), this operation is finished (End).

  When the above operation is received from the user A during the execution of the user B job (step S159; Yes), the multi-function device 60 interrupts the user B job and starts the job instructed by the user A ( Step S160). When the multifunction device 60 finishes the user A job, the multifunction device 60 resumes the suspended job of the user B (step S161). After the user B job is resumed, the first operation unit 62 again executes the job from the user A. It is monitored whether the operation is received (step S159; No to step S162; No). Then, without receiving the operation from the user A (step S159; No), when the job of the user B is finished (step S162; Yes), this operation is finished (End).

  In step S163 of FIG. 14, the multi-function device 60 displays a screen (copy setting screen or the like) tailored to the user B on the second display unit 63 (step S163), and the second operation unit 64 performs various operations from the user B. Here, various setting operations relating to copying are received (steps S165 to S166; No).

  In the case where the first operation unit (first display unit) is configured to be wirelessly connected to the apparatus body (see FIG. 11), the user A currently uses between step S163 and step S165. A warning is displayed on the wireless connection type first display unit that an operation by another user (in this case, user B) is started (step S164). Thereby, even when the user A is operating the first operation unit at a place away from the multi-function device 60 (device main body 60a), it can be understood that another user is simultaneously using the multi-function device 60. Further, the warning display may be performed even when the first operation unit is not a wireless connection type.

  Subsequently, when the multifunction device 60 receives a job execution operation (copy instruction operation by pressing the start button) from the user B through the second operation unit 64 (step S166; Yes), the user A's job (document file print job) ) Is executed (step S167; Yes), the job of the user A is interrupted and the job instructed by the user B is started (step S168). The multifunction device 60 resumes the suspended job of user A when the job of user B is terminated (step S169), and terminates this operation when the job of user A is terminated (End).

  When the user A job is not executed (step S167; No), the multi-function device 60 starts the job instructed by the user B (step S170), and performs the first operation during the execution of the user B job. The unit 62 monitors whether a job execution operation is received from the user A (step S171; No to step S172; No). Then, without receiving the operation from the user A (step S171; No), when the job of the user B is finished (step S172; Yes), this operation is finished (End).

  When the above operation is received from the user A during the execution of the user B job (step S171; Yes), the multi-function device 60 waits for the job instructed by the user A (step S173), and the user B job (Step S174; Yes), the job of the user A that has been waiting is executed (Step S175), and this operation is ended (End).

  In addition, although the case where the screen display and operation itself of the user A and the user B can be executed in parallel has been described as an example here, when the execution cannot be executed in parallel, the screen display control is performed based on the priority (authority) comparison result. Alternatively, the reception control of the operation may be switched.

  For example, when the priority of the user A is higher, in step S152 of FIG. 13, the screen that competes with the user A is not displayed on the second display unit used by the user B, and instead the higher priority. A message (notification screen) indicating that the user (user A) cannot use the screen because it is using the screen or another screen may be displayed. In addition, although a screen competing with the user A is displayed on the second display unit of the user B, an operation competing with the user A is not accepted by the second operation unit of the user B in step S153, and the priority is displayed on the second display unit. A message indicating that the user (user A) who is a high user (user A) cannot perform the operation because of competing operations may be displayed together. Further, when the use of the competing screen or the competing operation by the user A ends in the screen waiting state or the operation waiting state, the waiting state is canceled and a screen adapted to the user B is displayed on the second display unit. Or, the second operation unit may accept an operation from the user B.

  On the other hand, when the priority of the user B is higher, in step S164 in FIG. 14, for example, a user (user B) with a higher priority competes as a warning display on the first display unit used by the user A. After displaying a message indicating that the screen cannot be displayed because it has started using the screen to be used, or that the operation cannot be performed because a conflicting operation has been started, the conflicting screen is deleted or changed to another screen. You may make it be on hold. In addition, when the use of the competing screen or the competing operation by the user B ends in such a holding state, the screen released from the user B by releasing the holding state is displayed again on the first display unit, or the interrupted operation is performed. May be continuously received from the user A by the first operation unit.

  As described above, in the multi-function device 60 and the multi-function devices 70 and 80, user authentication using human body communication is individually performed for each touch operation performed on a plurality of operation panels (operation units) by a plurality of users and carried by each user. Since each user and each operation thereof can be identified based on the authentication data received from the terminal device 40, each operation of a plurality of identified users (user A and user B) as in the control operation according to this example. Can be received simultaneously (simultaneous operation). Further, when the operations by the simultaneous operation cannot be executed in parallel, the priority order of the operations is based on the result of comparing the priorities (authorities) determined in advance for the plurality of users. Each operation can be controlled according to the priority order. Operation efficiency and convenience can be improved by performing simultaneous operations of a plurality of users by such a plurality of operation units. In addition, the operation rate of the multifunction peripheral can be increased and productivity can be improved.

(Control operation example for multi-operation unit / multi-user simultaneous authentication / cooperation)
In a multi-function peripheral equipped with a plurality of operation units (operation panels) such as a main body and an external device, control other than the above-described individual authentication and simultaneous operation of a plurality of users is possible. For example, it is possible to control an operation for an operation involving simultaneous authentication by a plurality of users, more specifically, a control for a predetermined operation that a plurality of users should perform an operation in cooperation (cooperation control). To do.

  When two users are authenticated at the same time, for example, one user can authenticate the user by touching any part other than the operation member on one operation panel of the multi-function peripheral. However, it is possible to perform the operation after performing user authentication while operating the operation member on the other operation panel. It should be noted that it is possible to control a predetermined operation by a plurality of users with a multifunction machine having only one operation panel (operation unit). In that case, in order to avoid a decrease in operability due to multiple users approaching near the operation panel, a touch operation is applied to a part other than the operation panel, for example, a side surface of the apparatus main body. In addition, an electrode sheet and an electric field sensor for performing human body communication with the user terminal device 40 may be arranged, and the one user described above may be configured to authenticate by a touch operation on the specific location.

  FIG. 15 shows a control operation for simultaneous authentication and cooperative operation (joint work) of a plurality of users in a multi-function peripheral having a plurality of operation units. Here, user A is an operation approver, user B is an operator, and user B performs an operation (data input, setting, job execution, etc.) accompanied by authentication from the operation unit under the authentication status and monitoring of user A. A case will be described where the user A approves by monitoring the contents of the operation to the end, and the user B performs a collaborative operation to complete the operation. Such a cooperative operation prevents, for example, erroneous transmission of a facsimile that cannot be transmitted without approval in order to prevent erroneous transmission of confidential information due to, for example, an incorrect facsimile number or a change in the number of the other party. This includes operations such as printing confidential documents that cannot be output. Here, the multi-function device 60 will be described as an example.

  As the multifunction device 60 receives a touch operation from the user to the operation unit (arbitrary location other than the operation member) (step S181), the multifunction device 60 passes through a communication path including the user's human body from the terminal device 40 carried by the user. The authentication data is received, and an authentication process based on the authentication data is performed (step S182). When the authentication is impossible (step S183; NO), the multi-function device 60 ends this operation without permitting the use of this user (End).

  In the case of authentication permission (step S183; Yes), for example, when the user A who is the operation approver is authenticated by a touch operation on one operation unit (for example, the first operation unit), the multi-function device 60 is Information on user A (operation / management table for user A, etc.) is stored (step S184). Subsequently, it is monitored whether or not the user B who is the operation person receives a touch operation on the other operation unit (for example, the second operation unit), and when the touch operation is not received (step S185; No), For example, if a touch operation on the operation unit by the user B cannot be detected even after a predetermined time has elapsed, this operation is terminated (End).

  When a touch operation on the operation unit by the user B is received (step S185; Yes), the multi-function device 60 stores information on the user B (such as an operation / management table for the user B) (step S186), and the operation The user receives an operation that requires the approval of the user A from the user B (step S187). Thereafter, the multi-function device 60 performs authentication processing (user authentication) on the user A at regular intervals until the operation of the user B is completed (step S188 → step S189; Yes → step S189; No → step S187). .

  When the user A cannot be authenticated before the operation of the user B is completed (step S189; No), that is, the user A can receive the authentication data of the user A by releasing the hand from one of the operation units. When there is no more, the multi-function device 60 temporarily stops accepting the operation from the user B by the other operation unit, and monitors whether the user A can be authenticated again before the predetermined time elapses.

  When the user A can be authenticated within the predetermined time, that is, when the touch operation to one of the operation units by the user A can be detected (step S194; Yes), the multi-function device 60 cannot authenticate the user A. The operation received from the user B just before the timing is canceled (step S195), and the process returns to step S187. When the user A cannot be authenticated within the predetermined time, that is, when the touch operation to one of the operation units by the user A cannot be detected (step S194; No), the multi-function device 60 receives from the user B. All the operations are canceled (step S196), and this operation is terminated (End).

  When the multifunction device 60 receives a job execution operation from the user B in the other operation unit (step S190; Yes), the multifunction device 60 performs an authentication process (user authentication) on the user A, and the user performs the job execution operation at the time of the job execution operation. It is confirmed whether A can be authenticated (step S191). If user A cannot be authenticated (step S192; No), the process proceeds to step S194, and if user A can be authenticated within a predetermined time (step S194; Yes), only the job execution operation received last from user B is performed. Cancel (step S195) and return to step S187. If the user A cannot be authenticated within the predetermined time (step S194; No), the multi-function device 60 cancels all the operations received from the user B (step S196) and ends this operation (End).

  If the user A can be authenticated at the time when the job execution operation is received from the user B (step S192; Yes), the job instructed by the user B is executed (step S193), and this operation is terminated. (End).

  In this example, the case where the operation approver (user A) constantly monitors and approves the operation content of the operator (user B) has been described as an example (simultaneous authentication / cooperation operation). In addition to the approval method, it may be an approval method in which the operation approver confirms the operation details of the operator (setting status, input data, etc.) and approves (performs the approval operation) at the end (individual authentication / cooperation) operation).

  As described above, in the control operation of this example, regarding a predetermined operation that a plurality of users should perform an operation in cooperation with each other, whether or not the cooperative operation is performed is determined in conjunction with the detection of the operation on the operation unit. Inspection is performed based on the result of authentication (user identification result). In such a predetermined operation, a collaborative operation by a plurality of users can be inspected, so that it is possible to eliminate an operation mistake or an illegal single operation by one operator. In addition, since a predetermined operation by such a cooperative operation can be performed, variations of operations by a plurality of users are widened and convenience is improved.

  Further, in the simultaneous authentication / cooperation operation of this example, the multifunction peripheral touches its own device (operation unit) to recognize that the operation approver constantly monitors the operation content of the operator. This is detected and recognized by user authentication using human body communication. As described above, even if the operation approver does not touch the multi-function peripheral, the multi-function peripheral allows the operation approver standing in the authentication area to be configured by providing the authentication area (58) around the multi-function peripheral shown in FIG. You may make it detect and recognize by user authentication. In this case, since the operation approver only has to stand in the authentication area, the burden is reduced. The configuration shown in FIG. 6 is suitable for such simultaneous authentication / cooperation operation.

(Example of control operation for multiple operation units and single user takeover operation)
In a multi-function peripheral equipped with a plurality of operation units (operation panels) such as a main body and an external device, user authentication can be performed for each operation unit. For example, operation management for operations received from a user at the first operation unit It is also possible to receive an operation received from the user by the second operation unit as an operation of the user for the operation being managed. For example, there are cases in which operations of a plurality of steps in a single job are handed over between a plurality of operation units. Here, the control operation will be described.

  FIG. 16 illustrates a control operation for a takeover operation (continuous operation) between operation units by a single user in a multi-function peripheral having a plurality of operation units (continuous control). Here, the user A performs an image file editing operation with an external operation unit (large first operation unit), and then outputs (prints) the image file with the operation unit (small second operation unit) of the main body. , Facsimile transmission, distribution) and storage operations will be described. Here, the multi-function device 60 will be described as an example.

  As the multifunction device 60 receives a touch operation from the user to the first operation unit 62 (step S201), the multifunction device 60 receives authentication data from the terminal device 40 carried by the user through a communication path including the user's human body, An authentication process based on the authentication data is performed (step S202). If the authentication is impossible (step S203; NO), the multi-function device 60 ends this operation without permitting the use of this user (End).

  In the case of authentication permission (step S203; Yes), for example, when the user A is authenticated here, the multi-function device 60 permits the use to the user A. Subsequently, the multi-function device 60 stores user A information (operation / management table for user A, etc.) (step S204), and displays a screen (edit screen, etc.) tailored to user A on the first display unit 61. In step S205, the first operation unit 62 receives an operation for editing the image file stored in the multi-function device 60 from the user A (step S206).

  The multi-function device 60 does not receive an image file editing end operation from the user A by the first operation unit 62 or receives the editing end operation but does not receive a touch operation from the user A to the second operation unit 64 (Step S207; No), this operation is terminated (End).

  When the user A receives an image file editing end operation on the first operation unit 62 and then receives a touch operation on the second operation unit 64 from the user A (step S207; Yes), the multi-function device 60 performs the first operation. The first operation unit 62 (first display unit 61) is released in a logout state (step S208), and the operation takeover screen from the first display unit 61 is displayed on the second display unit 63 (step S209). In the operation takeover screen, for example, an image file that has been edited is already selected (designated) as a processing target.

  Here, the multi-function device 60 receives various operations related to the output of the image file from the user A by the second operation unit 64 (steps S210 to S211; No). Subsequently, when the multifunction device 60 receives a job execution operation from the user A by the second operation unit 64 (step S211; Yes), the multifunction device 60 executes the job of the user A (output of the image file) (step S212). Is terminated (End).

  In addition, although the case where operation was handed over from the 1st operation part 62 to the 2nd operation part 64 was demonstrated here as an example, the hand over method of operation is not restricted to this. For example, the operation may be taken over so as to reciprocate between two operation units, or the operation may be taken over by three or more operation units.

  As described above, in the control operation of this example, a specific user performs (continuously) the operation for the operation under management performed by the first operation unit by the second operation unit. Since operation with respect to the operation can be carried out between a plurality of different operation units, variations of operations by the plurality of operation units are widened, and convenience is improved. In addition, since one user does not occupy and operate a plurality of operation units at one time, the released operation unit can be used by other users, and operation efficiency (productivity) by a plurality of users can be improved. Enhanced.

  As mentioned above, although one embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to that shown in this embodiment, and there are changes and additions within the scope not departing from the gist of the present invention. Are also included in the present invention.

  For example, in the above-described embodiment, in a multi-function peripheral having a user authentication function, an example of a case where the user and the operation for each user related to the operation of the operation unit are identified and recognized by communicating with the user terminal device and performing user authentication. As described above, a configuration in which user authentication is not performed may be employed. That is, it is good also as a structure which identifies and recognizes the user who concerns on operation of an operation part, and operation for every user by communicating with a user's terminal device, performing only user identification, without performing user authentication.

  In addition, user identification (authentication) is performed each time an operation is detected for the operation unit, but may be changed according to the number of detected operations or the detected location. In the case of the number of detections, after the identification by the first operation detection, the identification may be performed every other operation detection or every second operation detection. In the case of a detection location, a condition may be set for each operation detection and every operation detection or every N times of operation detection, and identification may be performed based on the conditions. When a plurality of operation buttons (soft buttons) are displayed on the touch panel, the above conditions may be set for each operation button.

  For simultaneous operation by a plurality of users, for example, a single large screen in a large operation unit may be divided and assigned to each user, and each operation may be received from each user for each divided screen. . Further, such division of the screen may be automatically performed when another user touches the screen (touch panel) while the screen is used by one user.

  The information equipment apparatus (image processing apparatus) according to the present invention is not limited to the multi-function apparatus described in the embodiment, but may be an image processing apparatus such as a copier, a printer, or a facsimile machine, or an information processing apparatus including an operation unit. The present invention can be applied to various information equipment devices.
