  Next, the operation of the login support system 10 will be described. 5A and 5B are flowcharts showing processing for permitting login of the image forming apparatus by the server.

  When a person who wishes to enter the room 200 holds his / her ID card over the ID card reader device 12, the ID card reader device 12 reads the identification information ID from the IC chip of the ID card, and the read identification information. The ID is transmitted to the server 13.

  In the server 13, when the identification information ID transmitted from the ID card reader device 12 is received by the communication unit 240, the entrance / exit management unit 131 stores the received identification information ID in the person data storage unit 14. It is determined whether or not it matches the identification information ID (S101).

  When the identification information ID stored in the person data storage unit 14 matches the identification information ID transmitted from the ID card reader device 12 (S101 “Yes”), the entrance / exit management unit 131 The person who wishes to enter the room is authenticated as a person who is allowed to enter the room (S102). In addition, when the identification information IDs of the two do not match (S101 “No”), the entrance / exit management unit 131 does not authenticate the person who wants to enter the room.

  Thus, when the entrance / exit management unit 131 determines that the identification information IDs of the two do not match and does not authenticate the person who wants to enter, the entrance / exit management unit 131 performs control not to open the entrance gate 102 shown in FIG. By doing so, the entry of a person who wishes to enter this time may be restricted. At this time, the entrance / exit management unit 131 may display a message indicating that entry is not permitted on the display device 103 installed near the entrance gate 102. When performing such control, the entrance gate 102 includes an automatic lock opening / closing mechanism, is connected to the server 13, and opens and closes the lock by the automatic lock opening / closing mechanism in accordance with an instruction from the entrance / exit management unit 131. The display device 103 is connected to the server 13 and displays a display screen with contents in accordance with instructions from the entrance / exit management unit 131.

  On the other hand, each camera 11 </ b> A captures a person entering the room 200 and transmits each captured image to the server 13. The camera 11 </ b> B images the person who comes in front of the image forming apparatus 15 and transmits the captured image to the server 13. The camera 11 </ b> C images the defined area W (a person in the defined area W) and transmits the captured image to the server 13. In the server 13, these captured images are received by the communication unit 240 and are temporarily stored in the storage unit 230. The control unit 130 periodically repeats such imaging by the cameras 11A, 11B, and 11C and transmission / reception of the captured images from the cameras 11A, 11B, and 11C to the server 13.

  As described above, when the entrance / exit management unit 131 authenticates the person who wants to enter the room (S101 “Yes”, S102), the face authentication unit 132 captures each captured image captured by each of the cameras 11A and 11C. Detecting a face image of a person in the image, extracting feature points of the detected face image, and reading out the feature points of the face corresponding to the identification information ID of the person permitted to log in from the person data storage unit 14; It is determined whether or not the extracted feature point of the face image matches the feature point of the person's face corresponding to the identification information ID (S103). If they match, the detected face image is authenticated (S103). “Yes”).

  When the face image can be authenticated in this way, the control unit 130 stores the identification information ID of the person as the identification information ID of the person permitted to log in, and the person corresponding to the identification information ID of the person Is transmitted from the communication unit 240 to the image forming apparatus 15 (S104). The identification information ID, the name, and the display instruction for the name of the person are transmitted from the communication unit 240 to the image forming apparatus 15.

  In the image forming apparatus 15, when the communication unit 23 receives the identification information ID, the name, and the name display instruction of the person, the control unit 31 causes the display unit 21 to display the name. As a result, the names of persons who are permitted to log in can be recognized by persons around the image forming apparatus 15.

  When the face authentication unit 132 determines that the feature points do not match, the detected face image is not authenticated (S103 “No”), and the process returns to S101. That is, when the face image cannot be authenticated in this way, the control unit 130 cancels the person authentication performed in S102.

  That is, when the entry / exit management unit 131 authenticates the person who wants to enter, the person is permitted to enter the room 200, and when the face authentication unit 132 authenticates the face image as described above, The identification information ID is stored as the identification information ID of the person permitted to log in. Further, in the image forming apparatus 15, the name of the person who has been permitted to log in is displayed on the display unit 21, so that the name of the person who has been permitted to log in is displayed to persons around the image forming apparatus 15. Will be informed.

  Further, when the entrance / exit management unit 131 authenticates a person who wants to enter the room by using a built-in timer or the like, the control unit 130 starts measuring the elapsed time T from the authentication time (S105). Then, the control unit 130 determines whether or not the elapsed time T has reached a preset specified time TA (for example, 2 minutes) (S106).

  Here, the person permitted to log in should move to the front of the image forming apparatus 15 in order to use the image forming apparatus 15. In this case, a person who is permitted to log in is imaged by the camera 11B attached to the image forming apparatus 15.

  On the other hand, a person who is permitted to log in may not use the image forming apparatus 15 even when entering the room 200. At this time, there is a high possibility that the person moves outside the prescribed area W, which is a prescribed route from the entrance gate 102 to the image forming apparatus 15. In this case, depending on the camera 11C, the person permitted to log in is not captured.

  Furthermore, there may be a case where another person wants to enter the room 200 following the person permitted to log in. In this case, in order for the other person to enter the room, the ID card reader device 12 is caused to read the other person's ID card. Based on this, the ID card reader device 12 reads the identification information ID from another person's ID card. Then, the entrance / exit management unit 131 determines whether or not the identification information ID of the ID card matches the identification information ID stored in the person data storage unit 14, and if it matches, the other person is authenticated.

  Based on these, the processing after S106 will be described below.

  After the start of counting the elapsed time T, the control unit 130 determines whether another person is authenticated by the entrance / exit management unit 131 (S107) until the elapsed time T reaches the specified time TA (S106 “No”). Whether it is determined by the tracking unit 133 that the person permitted to log in has exited the prescribed area W (S108), and the login is permitted by the face authentication unit 132 based on the image captured by the camera 11B. It waits for each result of whether the face image of the person who has been authenticated has been authenticated again (S109).

  For example, until the elapsed time T reaches the specified time TA (S106 “No”), the person permitted to log in moves to the front of the image forming apparatus 15, and the person is imaged by the camera 11B. The face authentication unit 132 detects the face image from the captured image, and the face authentication unit 132 detects the feature image of the person's face image and the face image of the person whose identification information ID is specified in S103 and whose login is permitted. When it is determined that the feature points match (S107 “No”, S108 “No”, S109 “Yes”), that is, when the person moved in front of the image forming apparatus 15 is the same as the person permitted to log in, The control unit 130 transmits the identification information ID of the person and a login execution instruction to the person from the communication unit 240 to the image forming apparatus 15 (S110).

  In the image forming apparatus 15, when the identification information ID and the login execution instruction are received by the communication unit 23, the control unit 31 sets the image forming apparatus 15 in a state where the person indicated by the identification information ID is logged in. The control unit 31 executes the job by operating the image forming apparatus 15 according to the operation of the operation unit 22 or the touch panel 24 by the person (user). At this time, the display control unit 33 hides the name of the person permitted to log in that has been displayed on the display unit 21 until then.

  After the job is executed in the login state, the communication control unit 34 of the image forming apparatus 15 receives from the communication unit 23 information indicating that the job has ended (information indicating that the job has been logged out) may be received from the server 13. Send to.

  In the server 13, when the communication unit 240 receives information indicating that the job has been completed from the image forming apparatus 15 (“Yes” in S <b> 111), the control unit 130 determines whether there is a login waiting (described later). (S112). When the control unit 130 determines that there is no waiting for login (S112 “No”), the processing from S101 is repeated.

  On the other hand, if the control unit 130 has not received information indicating that the job has been completed from the image forming apparatus 15 after transmitting the login execution instruction (S111 “No”), the processing from S106 is repeated. .

  In addition, in a state where the elapsed time T has not reached the specified time TA (S106 “No”), the person tracking unit 133 causes the person permitted to log in outside the specified area W without using the image forming apparatus 15. When it determines with having moved ("No" in S107, S108 "Yes"), the control part 130 erase | eliminates the identification information ID memorize | stored in S103 in order to permit the login of the said person (S113), ie, The permission of login for the person is canceled, and it is determined whether there is a waiting for login (S112). When the control unit 130 determines that there is no login waiting (S112 “No”), the processing from S101 is repeated.

  Furthermore, in a state where the elapsed time T has not reached the specified time TA (S106 “No”), the ID card reader device 12 reads the other person's ID card and acquires the other person's identification information ID. When the entrance / exit management unit 131 determines that the identification information ID acquired from the ID card matches the identification information ID stored in the person data storage unit 14 and authenticates the other person (S107 “Yes”). )), On condition that the face authentication of the other person is performed by the face authentication unit 132, the control unit 130 stores the identification information ID of the other person while waiting for login to the image forming apparatus 15 ( S114), the identification information ID of the other person, the name of the person, an instruction to display the name, together with information indicating that the other person is waiting for login, the communication unit And it transmits to the image forming apparatus 15 from 40. Thereafter, the process is repeated from S106. When the entrance / exit management unit 131 authenticates the other person (S107 “Yes”), if the face authentication unit 132 does not perform face authentication of the other person, the control unit 130 performs the face authentication. When the face authentication of the other person is performed by the unit 132, the identification information ID of the other person is stored as waiting for login to the image forming apparatus 15 (S114).

  In the image forming apparatus 15, when the communication unit 23 receives the identification information ID of the other person, the name of the person, a display instruction for the name, and information indicating that the other person is waiting for login, The display control unit 33 causes the display unit 21 to display the name of the person waiting for login and a message indicating that the person is waiting for login together with the name of the person permitted to log in at this time.

  That is, when another person is authenticated and enters the room 200, the other person is set as a person waiting for login. Further, the name of the other person who is waiting for login is displayed on the display unit 21 of the image forming apparatus 15, and the name of the person who is waiting for login is recognized by a person around the image forming apparatus 15.

  In addition, before the elapsed time T reaches the specified time TA (S106 “No”), when the entrance / exit management unit 131 further authenticates another second person (S107 “Yes”), the control unit 130 As the second waiting for login, the identification information ID of the second other person is stored (S114), the identification information ID of the second other person, the name of the person, and the display instruction of the name The information is transmitted from the communication unit 240 to the image forming apparatus 15 together with information indicating that another person is waiting for login. In the image forming apparatus 15, the display control unit 33 displays the names of the first and second persons waiting for login and a message indicating that they are waiting for login at this time. It is displayed on the display unit 21 together with the name of the person.

  Thereafter, until the elapsed time T reaches the specified time TA (S106 “No”), every time a further person is authenticated by the entry / exit management unit 131 (S107 “Yes”), the control unit 130 waits for login. Are stored (S114).

  If the controller 130 determines that the elapsed time T has reached the specified time TA without finishing the job (S111 “No”) in the image forming apparatus 15 (S106 “Yes”), the process proceeds to S103. The stored login identification information ID is erased (login permission is canceled) (S115). Subsequently, the control unit 130 determines whether the identification information ID of the person who is waiting for login at this time is stored (S116). When the control unit 130 determines that the identification information ID of the person waiting for login is not stored (S116 “No”), the processing from S101 is repeated.

  In addition, when the control unit 130 determines that the identification information ID of the person who is waiting for login is stored (S116 “Yes”), the identification information of the first person with the highest order of waiting for login ID is memorize | stored as identification information ID of the person who newly permits login (S117). The control unit 130 transmits the identification information ID, name, and display instruction for the name of the person who is permitted to log in from the communication unit 240 to the image forming apparatus 15. Thereafter, the processing from S105 is repeated. In this case, the measurement of the elapsed time T is started when the identification information ID of the person who is newly permitted to log in is stored in S117.

  By performing such processing, when a plurality of persons are authenticated by the entrance / exit management unit 131, the room 200 is sequentially controlled from the first person authenticated by the entrance / exit management unit 131 under the control of the control unit 130. Entry into the room and login of the image forming apparatus 15 are permitted.

  In the image forming apparatus 15, when the communication unit 23 receives the identification information ID of the person who is newly permitted to log in, the name, and the display instruction of the name of the person, the control unit 31 displays the name on the display unit 21. Let As a result, it is possible to make a person around the image forming apparatus 15 recognize the name of the person who is newly permitted to log in.

  In addition, after the end of the job in the image forming apparatus 15 (S111 “Yes”), the control unit 130 also determines that the identification information ID of the person waiting for login is stored (S112 “Yes”). ), The identification information ID of the first person who is in the highest order of waiting for login is stored as the identification information ID of the person who is newly permitted to log in (S117). The control unit 130 transmits the identification information ID, name, and display instruction for the name of the person who is permitted to log in from the communication unit 240 to the image forming apparatus 15. Thereafter, the processing from S105 is repeated.

  In addition, before the elapsed time T reaches the specified time TA (S106 “No”), the face authentication unit 132 authenticates the face image of the person whose identification information ID is specified and login is permitted in S103. For example, when another person has moved to the front of the image forming apparatus 15 in order to use the image forming apparatus 15 in the absence (S109 “No”), the other person is imaged by the camera 11B. . When the face authentication unit 132 detects the face image based on the captured image at this time, and the face authentication unit 132 authenticates the face image of another person who has stored the identification information ID while waiting for login in S114. Alternatively, when the face image of the person whose login identification information ID is canceled in S115 is authenticated (S201 “Yes”), the control unit 130 logs in the identification information ID of the other person and the other person. Is transmitted from the communication unit 240 to the image forming apparatus 15 (S202). That is, instead of the person permitted to log in or the other person who is waiting for login, the control unit 130 images the other person whose face image has been authenticated in S201. The login of the forming apparatus 15 is executed. Thereafter, the process proceeds to S106.

  In the image forming apparatus 15, when the identification information ID and the login execution instruction are received by the communication unit 23, the control unit 31 logs the image forming apparatus 15 into the other person indicated by the identification information ID. It will be in the state. The control unit 130 operates the image forming apparatus 15 and executes a job in accordance with the operation of the operation unit 22 or the touch panel 24 by the person (user).

  After the job is executed in the login state, the communication control unit 34 of the image forming apparatus 15 sends information indicating that the job has ended (information indicating logout) from the communication unit 23 to the server 13. Send to.

  On the other hand, in S201, the face authentication unit 132 authenticates the face image of another person who has stored the identification information ID in S114 and waits for the login, or the identification information ID of the person whose login identification information has been canceled in S115. When neither of the face images is authenticated (S201 “No”), that is, when the other person is not a person authenticated by the entrance / exit management unit 131 (for example, authentication by the entrance / exit management unit 131). If the person has entered the room 200 without receiving the request, the control unit 130 provides a login execution instruction as a guest, and a restricted login execution instruction for executing login after limiting functions. Then, the data is transmitted from the communication unit 240 to the image forming apparatus 15 (S203). Thereafter, the process proceeds to S106.

  In the image forming apparatus 15, when the restricted login execution instruction is received by the communication unit 23, the control unit 31 sets the image forming apparatus 15 in a state where the guest has logged in. However, in this case, the control unit 31 restricts the function to a predetermined function, and causes each operation mechanism of the image forming apparatus 15 to perform an operation based on the operation of the operation unit 22 or the touch panel 24 by another person. For example, in the copy operation, (i) in the image forming function, for example, the formation of a color image is prohibited and only a monochrome image is permitted, or (ii) the enlargement / reduction function is prohibited. , And so on. Under such conditions, the control unit 130 operates the image forming apparatus 15 and executes a job in accordance with the operation of the operation unit 22 or the touch panel 24 by the other person.

  Also in this case, after the job is executed in the login state, the communication control unit 34 of the image forming apparatus 15 may receive information indicating that the job is completed (information indicating that the user has logged out) from the communication unit 23. ) To the server 13.

  Thus, in this embodiment, when a person enters the room, the person is authenticated by the entry / exit management unit 131 based on the identification information ID of the person's ID card, and the person moves to the front of the image forming apparatus 15. When the feature point of the person's face image captured by the camera 11B matches the feature point of the person's face stored in the person data storage unit 14, the detected face image is authenticated and image formation by the person is performed. Since the login of the apparatus 15 is permitted, it is not necessary to perform a special login operation, and the login of the image forming apparatus 15 can be permitted.

  In addition, when another person is authenticated and enters the room after the person permitted to log in, the other person waits for login, and the job by the person permitted to log in is completed in the image forming apparatus 15. After the specified time TA has elapsed or after the login permission of the person permitted to log in is canceled, the login of another person is permitted, so that the image forming apparatus 15 can be used efficiently. . Further, since the names of the persons permitted to log in and the names of other persons waiting for login are displayed on the display unit 21 of the image forming apparatus 15, the persons permitted to log in and the persons waiting for login are displayed in the image forming apparatus. The person around 15 can be made to recognize.

  Further, another person comes in front of the image forming apparatus 15, and the camera 11B captures another person's face image. Based on the captured image at this time, the face authentication unit 132 waits for login. When the face image of another person or the like is authenticated, the control unit 130 permits the login to the image forming apparatus 15 with the other person or the like as the other person, and the face of another person or the like. If the image is not authenticated as a face image of another person or the like who is waiting for login, the control unit 130 permits the login of the image forming apparatus 15 with a function restriction to the other person. Therefore, also in this case, the image forming apparatus 15 is used efficiently.

  In the above embodiment, the names of persons who are permitted to log in and the names of other persons waiting to log in are displayed on the display unit 21 of the image forming apparatus 15. 21 may be displayed. In this case, for example, the face authentication unit 132 of the server 13 detects and extracts the face images of those persons from the captured image captured by the camera 11A or the like, and the control unit 130 extracts the extracted face image and its display instruction. Is transmitted from the communication unit 240 to the image forming apparatus 15.

  In the above-described embodiment, the control unit 130 determines whether to permit a person to log in to the image forming apparatus 15 based on the person authentication by the entrance / exit management unit 131 and the face authentication by the face authentication unit 132. However, the control unit 130 does not use the human face authentication by the face authentication unit 132, but only logs in the image forming apparatus 15 based on the person authentication by the entrance / exit management unit 131. It may be determined whether or not to allow. In this case, for example, the control unit 130 permits the person to log in the image forming apparatus 15 until the predetermined time elapses after the person is authenticated by the entrance / exit management unit 131, and the constant When the time elapses, control is performed such that the login of the image forming apparatus 15 is canceled.
