And Since the other configuration is the same as that of the second embodiment described above, the same elements will be denoted by the same reference signs, and the description thereof will not be repeated.
  • FIG. 28 is a diagram showing the configuration of the management server 2 according to the modified example 2-1.
  • the management server 2 of the present modification includes a user determination unit 217 and a control signal transmission unit 218 in addition to the configuration shown in FIG.
  • the user determination unit 217 receives a confirmation request from the control device 50, the user (first user) image (lost user image) acquired in step S25 of FIG. The image of the person (the second user) is compared, and it is determined whether the first user and the second user match, that is, the user who returned the forgotten item is the person or not.
  • the control signal transmission unit 218 transmits a control signal for opening the door 9 to the control device 50 if the user who returns the lost item is the person himself, and removes the lost item.
  • a control signal indicating that the door 9 can not be opened unless the returned user is the person in question is transmitted to the control device 50.
  • the control device 50 transmits a lost material occurrence signal or a lost person image to the management server (FIG. 26), transmits a confirmation request to the management server 2, receives a control signal, and opens the door 9. (FIG. 27) and the like are the same as in the second embodiment described above.
  • FIG. 29 is a diagram showing a method in which the management server 2 confirms whether or not the user who has returned a lost item is the person who left the lost item.
  • the management server 2 executes the process of FIG.
  • the management server 2 reads the image of the first user (the lost user image) from the storage device 23 (step S310), and compares the lost user image with the image of the second user who returned the lost item. Then, it is determined whether or not the first user matches the second user, that is, whether the user who has returned the lost item is the person himself (step S320).
  • step S320 If the determination is affirmative in step S320, the management server 2 transmits a control signal to the control device 50 to open the door 9 of the toilet booth 14 in which the lost item is generated (step S330). A control signal to the effect that it can not open is transmitted to the control device 50 (step S340).
  • the management server 2 can automatically determine whether or not the user who returned the lost item is the person himself, and there is no need for the person in charge to wait for this determination.
  • the management server 2 determines whether the user who returned the lost item is the person or not, but not limited to this, the control device 50 includes the user determination unit 217, and the first use It may be determined whether or not the person and the second user match, that is, the user who returns the lost item is the person or not.
  • the user determination unit 217 first determines whether the user who returned the forgotten item is the person or not and can not be determined as the person
  • the person in charge may be presented with the images of the first user and the second user to request confirmation. As a result, when it is possible to automatically confirm the identity of the person, the person in charge does not need to perform the confirmation work, and the load on the person in charge can be reduced.
