     An information processing system  1  shown in  FIG. 1  is configured with various terminals connected to a cloud network  3 . 
     In  FIG. 1 , as an example of a terminal connected to the cloud network  3 , a user terminal  4  operated by a user and a space management server  5  as an example of an information processing apparatus that manages the space  2  are shown. The space  2  is connected to the cloud network  3 . More specifically, various apparatuses are provided in the space  2 , and these apparatuses are connected to the cloud network  3 . 
     In the present exemplary embodiment, an electronic lock is attached to a door of the space  2 , and each of the spaces  2  can be locked. In the present exemplary embodiment, a person who has the authority to unlock the space  2  can use the space  2 . 
     In a case of unlocking the space  2 , the person performing unlocking operates the user terminal  4  thereof to give an instruction for the unlocking. This instruction is sent to the space management server  5 , and the space management server  5  receives the instruction. The space management server  5  gives an instruction for unlocking the space  2  that the instruction for unlocking has been given. Consequently, the electronic lock installed in the space  2  is activated, and the space  2  is unlocked. 
     In the present exemplary embodiment, a portable smartphone is assumed as the user terminal  4 . However, the portable user terminal  4  may be a so-called wearable terminal, a notebook computer, or a game terminal. 
     The space management server  5  manages various types of information related to the space  2 . The space management server  5  manages, for example, information for specifying a user, information for specifying the space  2  that is a reservation target, the start date and time of the reservation, and the end date and time of the reservation. 
     The information for specifying a user includes, for example, the name, the gender, the age, an account, a user ID, a password of a user, and management information attached to an individual. The information for specifying the space  2  that is a use target includes, for example, information for specifying an address or a location, and a name or a number for management. 
     The space management server  5  also functions as a control apparatus and controls various apparatuses installed in the space  2 . 
     The control apparatus may be installed in each space  2  so as to correspond to each of the spaces  2 . In this case, the control apparatus installed in each space  2  controls various apparatuses installed in each space  2 .

     The information acquisition device  29  is configured with, for example, a reader that reads a ID card that is put thereon. The information acquisition device  29  may be a reader or the like that reads a user&#39;s fingerprint, arrangement of veins, or the like. 
     Although not shown, the booth  80  is provided with an air conditioner adjusting a temperature inside the booth  80 . 
       FIG. 4  is a diagram showing an example of the hardware configuration of the space management server  5 . 
     The space management server  5  as an example of the information processing apparatus has a control unit  101  that controls an operation of the entire apparatus, an information storage device  102  that stores information, and a network interface  103  that realizes communication via a local area network (LAN) cable or the like. 
     The control unit  101  has a central processing unit (CPU)  111  as an example of a processor, a read only memory (ROM)  112  in which basic software, a basic input output system (BIOS), and the like are stored, and a random access memory (RAM)  113  that is used as a work area. 
     The CPU  111  may be multi-cores. The ROM  112  may be a rewritable non-volatile semiconductor memory. The control unit  101  is a so-called computer. 
     The information storage device  102  is configured with, for example, a hard disk drive. In other words, the information storage device  102  is configured with, for example, a device that reads and writes data to and from a non-volatile storage medium in which a magnetic material is coated on a surface of a disk-shaped substrate. However, the information storage device  102  may be a semiconductor memory or a magnetic tape. 
     The space management server  5  also includes input devices such as a keyboard and a mouse, and a display device such as a liquid crystal display as necessary. 
     The control unit  101 , the information storage device  102 , and the network interface  103  are connected to each other via a bus  104  or a signal line (not shown). 
     Here, a program executed by the CPU  111  may be provided to the space management server  5  in a state of being stored in a computer-readable recording medium such as a magnetic recording medium (a magnetic tape, a magnetic disk, or the like), an optical recording medium (an optical disk or the like), a magnetooptical recording medium, or a semiconductor memory. 
     The program executed by the CPU  111  may be provided to the space management server  5  by using communication means such as the Internet. 
       FIG. 5  is a diagram showing an example of a hardware configuration of the user terminal  4 . In the configuration shown in  FIG. 5 , a case where the user terminal  4  is a smartphone is assumed. 
     The user terminal  4  has a control unit  201  that controls an operation of the entire apparatus, a memory card  202  that stores various data, various communication interfaces  203  that comply with wireless communication standards, an input device  204  such as a touch sensor, a display device  205  such as a liquid crystal display or an organic electroluminescence (EL) display, and a global positioning system (GPS) sensor  206 . 
     The control unit  201  has a CPU  211 , a ROM  212  in which firmware, a BIOS, and the like are stored, and a RAM  213  used as a work area. The CPU  211  may be multi-cores. The ROM  212  may be a rewritable non-volatile semiconductor memory. 
     The communication interface  203  is, for example, an interface used for connection to a mobile communication system or an interface used for connection to a wireless LAN. 
     The GPS sensor  206  is a sensor that receives radio waves from GPS satellites and measures a position of the user terminal  4 . Latitude, longitude, and altitude information output from the GPS sensor  206  provides the current position of the user terminal  4 . The GPS sensor  206  may be compatible with an indoor positioning system. 
     In the embodiments above, the term “processor” refers to hardware in a broad sense. Examples of the processor include general processors (e.g., CPU: Central Processing Unit) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable logic device). 
     In the embodiments above, the term “processor” is broad enough to encompass one processor or plural processors in collaboration which are located physically apart from each other but may work cooperatively. The order of operations of the processor is not limited to one described in the embodiments above, and may be changed. 
       FIG. 6  is a diagram showing an example of a display screen displayed on the user terminal  4  of a user when the user of the booth  80  reserves the booth  80 . 
     A map is displayed on the display screen shown in  FIG. 6 , and a plurality of installation locations of the booth  80  are displayed on the map. 
     In the present exemplary embodiment, when reserving the booth  80 , first, the user of the booth  80  selects an installation location from among the plurality of displayed installation locations. 
     The present exemplary embodiment is not limited to such a display form, and for example, a plurality of installation locations may be displayed in a list form, and the user may select an installation location from the list. 
     In a case where the installation location is selected, as shown in  FIG. 7  (a diagram showing another example of the display screen displayed on the user terminal  4 ), a vacancy status at the selected installation location is displayed hourly on the user terminal  4 . 
     The user performs an operation on the display screen to designate a reservation time for the booth  80 . The user presses a confirmation button (not shown). 
     Consequently, the space management server  5  performs a reservation confirmation process. 
     Specifically, the space management server  5  receives information regarding the installation location of the booth  80  and the reservation time, and then registers the information regarding the installation location and the reservation time in the information storage device  102  ( FIG. 4 ) to perform the reservation confirmation process. A confirmation result of the reservation is transmitted to the user terminal  4  and the reservation person is notified thereof. 
       FIG. 8  is a flowchart showing a flow of processes executed by the CPU  111  provided in the space management server  5  when a user enters the reserved booth  80 . Each process described below may be performed by a control apparatus (not shown) provided in the booth  80  instead of the space management server  5 . 
     In the present exemplary embodiment, the CPU  111  acquires information regarding the user&#39;s status before the user enters the booth  80  that is an example of a place used by the user. 
     Specifically, first, when the user enters the booth  80 , the CPU  111  determines whether or not the user is wearing a mask (step S 101 ). Specifically, the CPU  111  analyzes an image obtained by the external imaging device  291  (refer to  FIG. 2 ) to determine whether or not the user entering the booth  80  is wearing a mask. 
     In a case where the CPU  111  determines in step S 101  that the user is wearing a mask, the CPU  111  determines whether or not the user has a fever based on an output from the thermosensor  293  (refer to  FIG. 2 ) (step S 102 ). In other words, the CPU  111  determines whether or not the user&#39;s fever exceeds a predefined threshold value. 
     In a case where the CPU  111  determines in step S 102  that there is no fever, the CPU  111  determines whether or not the user is coughing (step S 103 ). Specifically, the CPU  111  determines whether or not the user is coughing based on an image obtained by the external imaging device  291  or sound obtained by the external microphone  292  (refer to  FIG. 2 ). 
     In a case where the CPU  111  determines in step S 103  that the user is not coughing, the CPU  111  provides a notification for prompting the user to disinfect the fingers with alcohol (step S 104 ). 
     Specifically, the notification for prompting the user to disinfect the fingers with alcohol is provided to the user outside the booth  80  via the external speaker  294  (refer to  FIG. 2 ) or the external monitor  295 . 
     Thereafter, the CPU  111  determines whether or not the user has performed alcohol disinfection based on an image acquired by the external imaging device  291  (step S 105 ). 
     A storage container containing a disinfectant solution such as alcohol may be stored inside a storage section (not shown) provided with an electronic lock, for example. In this case, in a case where the user outside the booth  80  is a reservation person of the booth  80 , the electronic lock may be unlocked such that this user can access the storage container containing the disinfectant solution. 
     Here, as to whether or not the user outside the booth  80  is a reservation person of the booth  80 , for example, the user terminal  4  is asked to send identification information for authentication. Whether or not the user outside the booth  80  is a reservation person of the booth  80  is determined based on the identification information. 
     In a case where the CPU  111  determines in step S 105  that the user has performed alcohol disinfection, the CPU  111  requests the user to present a screen of a contact check application (step S 106 ). 
     The CPU  111  checks the screen and determines whether or not the user has contacted an infected person of an infectious disease in, for example, the past  14  days (step S 107 ). 
     Here, the “infectious disease” refers to a disease in which a pathogen such as a bacterium or a virus invades the body and causes symptoms. 
     More specifically, in step S 106  and step S 107 , first, the user&#39;s smartphone is directed toward the external imaging device  291  to acquire an image of the screen of the contact check application displayed on the smartphone. 
     The CPU  111  analyzes this image acquired by the external imaging device  291  to determine whether or not the user has contacted an infected person of an infectious disease in, for example, the past  14  days. 
     In a case where the CPU  111  determines that there is no contact between the user and an infected person, the CPU  111  performs determination to permit entry to the booth  80  (step S 108 ). 
     Consequently, in the present exemplary embodiment, the booth  80  is unlocked such that the user can enter the booth  80 . 
     The “contact check application” is an application that informs the user whether or not the user is near an infected person of an infectious disease. 
     In a case where the “contact check application” is installed in the user&#39;s smartphone, or the like, whether or not the user has been near the infected person is determined based on position information of the smartphone and position information of a smartphone possessed by the infected person described above. 
     In a case where the CPU  111  determines that the user is has been near the infected person, the user is notified of information indicating that the user has been near the infected person via the user&#39;s smartphone. 
     On the other hand, in a case where the CPU  111  determines that the user is not wearing a mask in step S 101 , the CPU  111  performs determination to prohibit the user from entering the booth  80  (step S 109 ). 
     In other words, the CPU  111  performs determination to prohibit the user from entering the booth  80  in a case where a status of the user before entering the booth  80  is a specific status such as not wearing a mask. 
     Similarly, the CPU  111  performs determination to prohibit the user from entering the booth  80  in a case where the CPU  111  determines that the user has a fever in step S 102  or the user is coughing in step S 103  (step S 109 ). 
     The CPU  111  also performs determination to prohibit the user from entering the booth  80  in a case where the CPU  111  determines that the user has not performed alcohol disinfection in step S 105 , or the user has contacted the infected person in step S 107  (step S 109 ). 
     In this case, the CPU  111  does not give an instruction for unlocking the booth  80 , and the booth  80  remains locked. 
     In a case where the CPU  111  performs determination to prohibit the user from entering the booth  80 , the CPU  111  notifies the user that the user cannot enter the booth  80 . Specifically, the CPU  111  notifies the user that the user cannot enter the booth  80  via the user terminal  4 , the external monitor  295 , or the like. 
     In a case where the CPU  111  performs determination to prohibit the user from entering the booth  80 , in a case where the user has already been charged, the CPU  111  performs a refund process. 
     In addition, in a charging form in which the user is charged after the user finishes using the booth  80 , the CPU  111  does not charge the user in a case where a determination is made to prohibit the user from entering the booth  80 . 
       FIG. 9  is a flowchart showing a flow of processes executed by the CPU  111  after the user enters the booth  80 . 
     After the user enters the booth  80 , the CPU  111  performs processes in step S 201  to step S 210  shown in  FIG. 9  every time a predefined time elapses. Specifically, the CPU  111  acquires behavior information that is information regarding behaviors performed by the user in the booth  80  every time a predefined time elapses. 
     More specifically, every time a predefined time elapses, the CPU  111  first analyzes the image obtained by the internal imaging device  24  to determine whether or not the user has touched the face thereof and then touches the room (the inside of the booth  80 ) (step S 201 ). 
     In a case where the CPU  111  determines that the user has performed an action (behavior) of touching the room after touching the face, the CPU  111  records a usage status of the user (step S 202 ). Specifically, in this case, the CPU  111  registers information indicating that the user has performed the action of touching the room after touching the face in the information storage device  102  (refer to  FIG. 4 ). 
     On the other hand, in a case where the CPU  111  determines in step S 201  that the user has not performed the action of touching the room after touching the face, the CPU  111  analyzes the image obtained by the internal imaging device  24  and determines whether the user is wearing a mask (step S 203 ). 
     In a case where the CPU  111  determines that the user is not wearing the mask, the CPU  111  warns the user (S 204 ). Specifically, the CPU  111  provides a notification for prompting the user to wear the mask via the internal monitor  32  or the internal speaker  30 A. 
     Next, in this case, the CPU  111  performs the process in step S 202  and records a usage status of the user. Specifically, in this case, the CPU  111  registers information indicating that the user is not wearing the mask in the information storage device  102 . 
     In a case where the CPU  111  determines in step S 203  that the user is wearing the mask, the CPU  111  determines whether or not the user is coughing (step S 205 ). 
     Specifically, the CPU  111  determines whether or not the user is coughing in the booth  80  based on the image acquired by the internal imaging device  24  or the sound acquired by the internal microphone  297 . 
     In a case where the CPU  111  determines that the user is coughing, the CPU  111  determines whether or not the cough is caused by a predefined specific factor such as a cough caused by a coronavirus (step S 206 ). 
     In recent years, a technique has been developed in which sound of a cough obtained by a microphone is analyzed, and thus whether this cough is caused by a specific factor such as a coronavirus can be determined. In the process in step S 206 , the CPU  111  determines whether or not the cough is caused by a predefined specific factor by analyzing the sound of the cough. 
     In a case where the CPU  111  determines in step S 206  that the cough is not caused by a specific factor, the CPU  111  performs the process in step S 202  and records the usage status of the user. Specifically, in this case, the CPU  111  registers information indicating that the user has coughed in the information storage device  102 . 
     Also in a case where the CPU  111  determines in step S 206  that the cough is caused by a specific factor, the CPU  111  records the usage status of the user (step S 207 ). 
     Specifically, in this case, the CPU  111  registers information indicating that the user has coughed due to a specific factor in the information storage device  102 . 
     In this case, as shown in step S 208 , the CPU  111  requests the user in the booth  80  to stop using the booth  80  (step S 208 ). 
     Specifically, the CPU  111  provides a notification for prompting the user to leave the booth  80  via, for example, the user terminal  4  or the internal monitor  32 . Consequently, the user leaves the booth  80 . 
     In other words, the CPU  111  provides a notification for prompting the user to leave the booth  80  in a case where the user has coughed due to a specific factor. 
     In other words, in a case where a behavior specified by the behavior information is a predefined specific behavior such as coughing caused by the coronavirus, the CPU  111  provides a notification for prompting the user to leave the booth  80 . 
     Consequently, the user leaves the booth  80  without waiting for the end of the reservation time for the booth  80 . 
     As described above, in a case where the user leaves the booth  80  without waiting for the end of the reservation time, in a case where the user has already charged, the charge for the unused time may be refunded. 
     Ina case of a charging form in which charging is performed after the booth  80  is used, the user may be charged for a time from the reservation start time for the booth  80  to a time when the user leaves the booth  80 . 
     On the other hand, in a case where the CPU  111  determines in step S 205  that the user is not coughing, the CPU  111  determines whether or not the usage time for the booth  80  has expired (step S 209 ). In other words, the CPU  111  determines whether or not the reservation end time of the booth  80  has come. 
     In a case where the CPU  111  determines that the usage time for the booth  80  has expired, the CPU  111  finishes the process (step S 210 ). 
     In the present exemplary embodiment, as described above, the CPU  111  acquires the behavior information that is information regarding the user&#39;s behavior in the booth  80  that is an example of a place used by the user. 
     More specifically, as described above, the CPU  111  acquires the behavior information that is information regarding a behavior that influences the degree of infection of an infectious disease with which the user infects other users via the booth  80 , such as a behavior of touching the room, a behavior of wearing a mask, or a behavior of coughing. 
     Various behaviors such as the behavior of touching the room after the user touches the face, the behavior of the user wearing a mask, and the behavior of the user coughing all influence the degree to which other users using the booth  80  after the user are infected with the infectious disease. 
     In the present exemplary embodiment, information regarding the user&#39;s behavior that influences the degree of infection is acquired. 
       FIG. 10  is a flowchart showing a flow of processes executed by the CPU  111  after the usage time for the booth  80  expires. 
     In a case where the reservation end time (reservation end time point) has come, the CPU  111  determines whether or not there is no user in the booth  80  based on an output from the human sensor  25  (refer to  FIG. 2 ) (step S 301 ). 
     In a case where the CPU  111  determines that there is a user in the booth  80 , the CPU  111  prompts the user in the booth  80  to leave the booth  80  via the internal speaker  30 A or the internal monitor  32  (step S 302 ). 
     On the other hand, in a case where the CPU  111  determines in step S 301  that there is no user in the booth  80 , the CPU  111  activates the electronic lock  22 C (refer to  FIG. 2 ) to lock the door  22  (step S 303 ). 
     Next, the CPU  111  ascertains the usage status for the booth  80  by the user who has used the booth  80  before the locking (step S 304 ). 
     Specifically, in the present exemplary embodiment, as described above, the usage status is registered in the information storage device  102 , and, in step S 304 , the registered usage status is read from the information storage device  102  to ascertain the usage status of the user. 
     Next, the CPU  111  determines whether the degree of contamination of the booth  80  is high based on the ascertained usage status (step S 305 ). 
     In a case where the CPU  111  determines that the degree of contamination of the booth  80  is high, the CPU  111  sets a cleaning mode of the booth  80  to a long-time cleaning mode (step S 306 ). 
     In the present exemplary embodiment, in a case where the cleaning mode is set to the long-time cleaning mode, the inside of the booth  80  is irradiated with ultraviolet light from the light source  296  (refer to  FIG. 2 ) during a first period of time. 
     In the present exemplary embodiment, a case where cleaning is performed by applying the ultraviolet light is described as an example, but the cleaning form is not limited to this, and a disinfectant solution maybe sprayed, a suction type robot vacuum cleaner may be operated, or a ventilation fan may be operated. 
     In the present exemplary embodiment, in a case where the degree of contamination of the booth  80  is determined as being high, the case where the cleaning mode of the booth  80  is set to the long-time cleaning mode is described as an example, but the present exemplary embodiment is not limited to this. 
     In a case where the degree of contamination of the booth  80  is determined as being high, an output during cleaning may be increased, for example, by increasing an output of the light source  296 . 
     In cleaning the booth  80 , the inside of the booth  80  is not limited to being cleaned uniformly, and cleaning may focus on a location of the booth  80  touched by a user or a location to which saliva (droplets) from the user&#39;s mouth is likely to be attached. 
     The location of the booth  80  touched by a user or the location to which saliva (droplets) from the user&#39;s mouth is likely to be attached may be ascertained by analyzing an image obtained by the internal imaging device  24 . 
     The CPU  111  determines whether or not the degree of contamination of the booth  80  is high based on, for example, three conditions that the user&#39;s mask wearing time ratio exceeds 80%, the number of coughs is less than five, and the number of touching the room after the user touches the face is less than five. 
     In a case where any one of the three conditions is not satisfied, the CPU  111  determines that the degree of contamination of the booth  80  is high. In a case where all the three conditions are satisfied, the CPU  111  determines that the degree of contamination of the booth  80  is not high. 
     Here, the “mask wearing time ratio” refers to a ratio of the user&#39;s mask wearing time to the time for which the user has stayed in the booth  80 . 
     In a case where the CPU  111  determines in step S 305  that the degree of contamination of the booth  80  is not high, in step S 307 , the CPU  111  determines whether the degree of contamination of the booth  80  is low. 
     In a case where the CPU  111  determines that the degree of contamination of the booth  80  is low, the CPU  111  sets the cleaning mode of the booth  80  to a simple cleaning mode (step S 308 ). 
     In a case where the cleaning mode is set to the simple cleaning mode, the inside of the booth  80  is irradiated with ultraviolet light during a short period of time. Specifically, the ultraviolet light is applied for a second period of time shorter than the first period of time described above. 
     In the present exemplary embodiment, in a case where the CPU  111  determines that the degree of contamination of the booth  80  is low, a case where the cleaning mode of the booth  80  is set to the short-time cleaning mode is described as an example, but a cleaning aspect is limited to this. 
     In a case where the degree of contamination of the booth  80  is determined as being low, an output during cleaning may be reduced by reducing an output of the light source  296 . 
     The CPU  111  determines whether or not the degree of contamination of the booth  80  is low based on, for example, three conditions that the user&#39;s mask wearing time ratio exceeds 99%, the number of coughs is less than two, and the number of touching the room after the user touches the face is less than one. 
     The CPU  111  determines that the degree of contamination of the booth  80  is low in a case where all of the three conditions are satisfied, and determines that the degree of contamination of the booth  80  is not low in a case where at least one of the three conditions is not satisfied. 
     In a case where the CPU  111  determines in step S 307  that the degree of contamination of the booth  80  is not low, that is, in a case where the degree of contamination of the booth  80  is neither high nor low and thus intermediate, the CPU  111  sets the cleaning mode of the booth  80  to a normal cleaning mode (step S 309 ). 
     In a case where the normal cleaning mode is set, the ultraviolet light irradiation time is longer than that in the simple cleaning mode, and the ultraviolet light irradiation time is shorter than that in the long-time cleaning mode. 
     Specifically, in a case where the normal cleaning mode is set, ultraviolet light is applied for a third period of time that is shorter than the first period of time and longer than the second period of time. 
     In the present exemplary embodiment, as described above, the CPU  111  determines cleaning of the booth  80  based on the behavior information that is information regarding a behavior performed by the user in the booth  80  and influencing the degree of infection of an infectious disease. 
     Specifically, the CPU  111  determines a cleaning time for the booth  80  based on the behavior information. 
     More specifically, in the present exemplary embodiment, in a case where a behavior specified by the behavior information is a predefined specific behavior, the CPU  111  increases or reduces a cleaning time compared with a case where the behavior is not the specific behavior. 
     Specifically, for example, as described above, in a case where the behavior specified by the behavior information is the behavior of touching the room after the user touches the face, the CPU  111  increases the cleaning time. 
     On the other hand, for example, in a case where the behavior specified by the behavior information is not the behavior of touching the room after the user touches the face, the CPU  111  reduces the cleaning time. In other words, the CPU  111  reduces the cleaning time in a case where the user has performed the behavior of touching the room after the user touches the face thereof. 
       FIG. 11  is a flowchart showing a flow of schedule adjustment for cleaning the booth  80 . In other words,  FIG. 11  is a flowchart showing a flow of schedule adjustment for cleaning the booth  80  after the booth  80  has been used. 
     In schedule adjustment for cleaning, first, the CPU  111  ascertains a usage status for the booth  80  of a user (hereinafter, this user will be referred to as a “preceding user”) while the preceding user is using the booth  80  (step S 401 ). 
     In the present exemplary embodiment, as described above, the usage status is registered in the information storage device  102  every time a predefined time elapses. 
     The CPU  111  reads the usage status from the information storage device  102  while the preceding user is using the booth  80 , and ascertains the usage status of the preceding user. 
     The CPU  111  determines whether or not the booth  80  needs to be cleaned for a long time (hereinafter, referred to as “long-time cleaning” in some cases) based on the ascertained usage status (step S 402 ). 
     Specifically, in this case, the CPU  111  determines whether or not the above three conditions are satisfied based on the ascertained usage status. 
     That is, the CPU  111  determines whether or not the three conditions that the mask wearing time ratio of the preceding user exceeds  80 %, the number of coughs is less than five, and the number of touching the room after the preceding user touches the face is less than five are satisfied. 
     In a case where the CPU  111  determines in step S 402  that the three conditions are satisfied and the booth  80  does not need to be cleaned for a long time, the CPU  111  determines whether or not the usage time for the booth  80  has expired (step S 403 ). 
     In a case where the CPU  111  determines in step S 403  that the usage time for the booth  80  has not expired, the CPU  111  returns to the process in step S 401 . 
     On the other hand, in a case where the CPU  111  determines in step S 403  that the usage time for the booth  80  has expired, the CPU  111  finishes the process. In this case, the booth  80  is cleaned in the above-described normal cleaning mode. 
     On the other hand, in a case where the CPU  111  determines in step S 402  that any of the three conditions is not satisfied and the booth  80  needs to be cleaned fora long time, the process proceeds to step S 404 . 
     In step S 404 , the CPU  111  determines whether or not the cleaning (long-time cleaning) performed after the usage time for the booth  80  expires influences a user who has made the next reservation (hereinafter, referred to as a “subsequent user”) (step S 404 ). 
     In a case where the CPU  111  determines in step S 404  that cleaning (long-time cleaning) does not influence the subsequent user, the CPU  111  performs the process in step S 403  and determines whether or not the usage time (reservation time) has expired. 
     In step S 403 , in a case where the CPU  111  determines that the usage time has expired, the CPU  111  finishes the process. 
     In this case, long-time cleaning is performed after the usage time for booth  80  by the preceding user. In this case, this long-time cleaning does not influence the usage of the booth  80  by the subsequent user. 
     In contrast, in a case where the CPU  111  determines in step S 404  that the long-time cleaning influences the subsequent user, the CPU  111  determines whether or not a time period next to the reservation time period reserved by the subsequent user is free (step S 405 ). 
     In a case where the CPU  111  determines in step S 405  that the next time period is free, the CPU  111  inquires the subsequent user about whether the reservation is changeable (step S 406 ). Specifically, the CPU  111  inquires about whether the reservation is changeable via the user terminal  4  or the like. More specifically, the CPU  111  inquires about whether or not the reservation is changeable to the above next time period. 
     In a case where there is a response from the subsequent user, the CPU  111  determines whether or not to change the reservation based on this response (step S 407 ). 
     In a case where the CPU  111  determines that the reservation is to be change, the CPU  111  changes the reservation (step  408 ). More specifically, the CPU  111  determines that the reservation is changed in a case where the subsequent user permits the change, and changes the reservation. 
     In other words, in this case, the CPU  111  changes the reservation of the subsequent user in a case where the subsequent user who is an example of another user different from the preceding user has given permission. 
     More specifically, in this case, the CPU  111  changes the reservation time of the reservation of the subsequent user. 
     In this case, the CPU  111  changes the reservation time of the subsequent user to the above next time period, and further notifies the subsequent user that the reservation has been changed. 
     More specifically, in this case, the CPU  111  makes a change to shift the start of the original reservation time of the subsequent user backward, and also makes a change to shift the end of the reservation time backward. The CPU  111  notifies the subsequent user that the reservation has been changed. 
     In this case (in a case where the reservation is changed), the CPU  111  gives an instruction for starting the long-time cleaning in a case where the reservation time of the preceding user has expired. 
     In this case, the long-time cleaning is performed over both a time period in which the long-time cleaning is originally scheduled and a time period that is free due to the above reservation change. 
     On the other hand, in a case where the CPU  111  determines in step S 407  that the reservation is not to be changed, the CPU  111  inquires the subsequent user about whether to reduce the usage time to discount the charge or cancel the reservation (step S 409 ). 
     The CPU  111  determines whether or not there is a response that the reservation is canceled (step S 410 ). In a case where the CPU  111  determines that there is a response that the reservation is canceled, the CPU  111  cancels the reservation for the booth  80  of the subsequent user (step S 411 ). 
     In other words, the CPU  111  cancels the reservation for the booth  80  of the subsequent user in a case where the subsequent user has given a permission. 
     In a case where a cleaning time of the cleaning performed after the use of the preceding user overlaps the reservation time for the booth  80  of the subsequent user, the reservation for the booth  80  of the subsequent user may be canceled as described above. 
     In the present exemplary embodiment, the cleaning time is determined, such as the above-described normal cleaning mode, simple cleaning mode, and long-time cleaning mode. 
     In the present exemplary embodiment, in a case where the long-time cleaning mode is determined and thus the cleaning time is determined to be a long cleaning time, a situation may occur in which the determined cleaning time overlaps the reservation time for the booth  80  of the subsequent user. In this case, as described above, the reservation for the booth  80  of the subsequent user may be canceled. 
     In this case, in a case where the reservation time of the preceding user has expired, the CPU  111  gives an instruction for starting the long-time cleaning. 
     In this case, the long-time cleaning is performed over both a time period in which the long-time cleaning is originally scheduled and a time period that is free due to the above reservation cancelation. 
     On the other hand, in a case where the CPU  111  determines in step S 410  that there is no response that the reservation is canceled, the CPU  111  performs a process of reducing the usage time for the booth  80  of the subsequent user and discounting the charge (step S 412 ). 
     Specifically, the CPU  111  performs setting to delay the reservation start time of the subsequent user and setting to discount the charge by an amount of the delayed time. 
     In other words, in this case, the CPU  111  makes a change to shift the start of the reservation time of the subsequent user backward, and performs setting to discount the charge by a time of shifting the start backward. 
     In this case, the CPU  111  does not shift the end of the reservation time backward. 
     In the present exemplary embodiment, as described above, in a case where the CPU  111  sets the cleaning mode to the long-time cleaning mode and thus the cleaning time is determined to be a long time, the cleaning time determined by the CPU  111  overlaps the reservation time for the booth  80  of the subsequent user. 
     In this case, as described above, a change to shift the start of the reservation time backward may be made. Consequently, the cleaning time and the usage time for the booth of the subsequent user do not overlap each other. 
     Also in this case, the CPU  111  gives an instruction for starting the long-time cleaning in a case where the reservation time of the preceding user has expired. 
     In this case, the long-time cleaning is performed over both a time period in which the long-time cleaning is originally scheduled and a time period that is free by shifting the start backward. 
     In the present exemplary embodiment, even in a case where the CPU  111  determines in step S 405  that the next time period is not free, the CPU  111  executes the process in step S 412  to perform a process of reducing the reservation time for the booth  80  of the subsequent user to discount the charge. 
     Also in this case, the long-time cleaning is performed over both a time period in which the long-time cleaning is originally scheduled and a time period that is free by shifting the start backward. 
     In a case where the CPU  111  determines in step S 405  that the next time period is not free, the process in step S 409  may be performed to inquire the subsequent user about whether to reduce the usage time to discount the charge or cancel the reservation. 
     In this case, in the same manner as above, the usage time for the booth  80  of the subsequent user is reduced and the charge is discounted, or the reservation for the booth  80  is cancelled. 
     In this case, in the same manner as above, the long-time cleaning is performed over both a time period in which the cleaning is originally scheduled and a time period that is free by shifting the start backward or canceling the reservation. 
       FIGS. 14A and 14B  are diagrams showing specific examples of schedule adjustment. 
     In this example, a time period indicated by the reference sign  14 A in  FIG. 14A  is a time period in which the preceding user is using the booth  80 . 
     In this example, a process is performed in which reservations are not continuously made, and, thus, as indicated by the reference sign  14 B, a free time period for which a reservation is not made is secured between reservation time periods that precede and succeed temporally. 
     In other words, in the present exemplary embodiment, a plurality of reservable frames are provided every 30 minutes, but a free time period for which a reservation is not made is secured between a reservable frame for which a reservation has already been made and the same reservable frame for which a reservation has already been made. 
     More specifically, in the present exemplary embodiment, in order to secure the cleaning time for the booth  80 , a free time period for which a reservation is not made is secured between a certain reservable frame for which a reservation has already been made and another reservable frame for which a reservation has already been made. 
     In the present exemplary embodiment, the booth  80  is cleaned during the free time period. More specifically, in the present exemplary embodiment, cleaning in the normal cleaning mode, cleaning in the simple cleaning mode, and cleaning in the long-time cleaning mode are performed in this free time period. 
     Here, the “reservable frame” refers to a time frame of which the start and the end are predefined and in which a user reserves the booth  80 . 
     In the present exemplary embodiment, as described above, the usage status of the preceding user is acquired. The long-time cleaning may be performed as described above depending on the usage status of the preceding user. 
     Here, in a case where the cleaning in the simple mode or the cleaning in the normal mode is performed, the cleaning is performed in a free time period indicated by the reference sign  14 E in  FIG. 14A . 
     In this case, since the cleaning is finished in this free time period, this cleaning does not influence a reservation time frame (reservation time period) reserved by the subsequent user, indicated by the reference sign  14 F. 
     On the other hand, in a case where a status specified by the usage status of the preceding user is a status in which the degree of contamination is high, the long-time cleaning is performed. 
     In this case, cleaning is required to be performed not only in the free time period indicated by the reference sign  14 E but also in the reservation time frame (time frame indicated by the reference sign  14 F) reserved by the subsequent user, and thus this long-time cleaning influences the subsequent user. 
     In other words, in this case, the cleaning time of the long-time cleaning and the reservation time frame of the subsequent user temporally overlap each other, and thus the long-time cleaning influences the subsequent user. 
     In the present exemplary embodiment, in a case where the long-time cleaning is performed, whether or not the next reservation time frame of the reservation time frame of the subsequent user is free is determined as described above. 
     Specifically, in this example, whether or not a time frame indicated by the reference sign  14 G in  FIG. 14A  is free is determined. 
     In this example, in a case where the time frame indicated by the reference sign  14 G is free, the reservation is changed with the permission of the subsequent user, and the reservation time frame of the subsequent user is changed to the time frame indicated by the reference sign  14 G in  FIG. 14A . 
       FIG. 14B  is a diagram showing a usage status and a reservation status of the booth  80  after the reservation time frame of the subsequent user is changed to the time frame indicated by the reference sign  14 G in  FIG. 14A . 
     In this example, as a result of changing the reservation time frame of the subsequent user, a new reservation time frame of the subsequent user is a time frame indicated by the reference sign  14 J in  FIG. 14B . 
     In this case, the long-time cleaning is performed over both a time frame indicated by the reference sign  14 K in  FIG. 14B  (a time frame in which cleaning is scheduled from the beginning) and a time frame indicated by the reference sign  14 L (a time frame that is free due to a reservation change). 
     On the other hand, for example, in a case where the time frame indicated by the reference sign  14 G in  FIG. 14A  is not free, the reservation of the subsequent user cannot be changed. 
     In this case, as described above, the subsequent user is inquired about whether to reduce the usage time or cancel the reservation. 
     In a case where there is a response that the usage time is reduced, the long-time cleaning is performed over both a time frame indicated by the reference sign  14 E in  FIG. 14A  (a time frame in which the cleaning is scheduled from the beginning) and a time frame that is free by reducing the usage time in the time frame indicated by the reference sign  14 F. 
     In a case where there is a response that the reservation is canceled, the long-time cleaning is performed over both a time frame indicated by the reference sign  14 K in  FIG. 14B  (a time frame in which the cleaning is scheduled from the beginning) and a time frame indicated by the reference sign  14 L. 
       FIG. 12  is a flowchart showing a flow of processes executed by the CPU  111  with respect to a usage fee or the like for the booth  80 . 
     Immediately before the reservation end time for the booth  80 , the CPU  111  reads the usage status from the information storage device  102  and acquires the usage status in the same manner as described above (step S 501 ). 
     The CPU  111  ascertains a mask usage time ratio, the number of coughs, and the number of touching the room after touching the face based on the acquired usage status, and generates a graph representing such information (step S 502 ). 
     Next, the CPU  111  displays the usage status including the graph generated in step S 502  on the internal monitor  32  (refer to  FIG. 2 ) (step S 503 ). As described above, displaying the usage status of the user and informing the user thereof raises the user&#39;s awareness of an infectious disease. 
     In a case where the user is informed of the usage status, a specific action among actions actually performed by the user in the booth  80  may be displayed on the internal monitor  32 . 
     Specifically, for example, an image obtained by the internal imaging device  24 , such as an image in which the user is not wearing a mask, an image in which the user is coughing, or an image in which the user touches the room after touching the face may be displayed on the internal monitor  32 . 
     Thereafter, in the present exemplary embodiment, information regarding the usage status including the information included in the generated graph is encrypted and stored (step S 504 ). Specifically, the usage status is encrypted and then registered in the information storage device  102 . 
     Next, the CPU  111  determines whether or not the degree of contamination of the booth  80  is low based on the usage status acquired in step S 501  (step S 505 ). 
     Specifically, in the same manner as described above, the CPU  111  determines whether or not the degree of contamination of the booth  80  is low is based on, for example, three conditions that the user&#39;s mask wearing time ratio exceeds  99 %, the number of coughs is less than two, and the number of touching the room after the user touches the face is less than one. 
     In a case where the CPU  111  determines in step S 505  that the degree of contamination of the booth  80  is low, the CPU  111  discounts the charge for the booth  80  or gives points that can be allocated as a part of the charge when the booth  80  is used from the next time onward (step S 506 ). 
     In the above description, the case of acquiring information regarding whether or not a user&#39;s behavior is a behavior of contaminating the booth  80  as the behavior information has been described, but acquired information is not limited to this, and information regarding a behavior of making the booth  80  clean, such as a behavior of cleaning the inside of the booth  80  may be acquired as the behavior information. 
     In a case where information regarding a behavior of cleaning the booth  80 , such as a cleaning behavior, is acquired, the charge for the booth  80  may be discounted, or points that can be allocated as a part of the charge when the booth  80  is used from the next time onward may be given. 
     In a case of a pre-use charging form in which the charge for the booth  80  is discounted and charging is performed before using the booth  80 , the discounted charge is refunded to the user. 
     In a case of a post-use charging form in which the charge for the booth  80  is discounted and charging is performed after the booth  80  is used, the discounted charge is added to the user. 
     On the other hand, in a case where the CPU  111  determines in step S 505  that the degree of contamination of the booth  80  is not low, the CPU  111  determines whether the degree of contamination of the booth  80  is high (step S 507 ). 
     Specifically, the CPU  111  performs a determination based on, for example, three conditions that the user&#39;s mask wearing time ratio does not exceeds  80 %, the number of coughs is equal to or more than five, and the number of touching the room after the user touches the face is equal to or more than five. 
     In a case where any one of the three conditions is satisfied, the CPU  111  determines that the degree of contamination of the booth  80  is high. In this case, the CPU  111  adds an additional charge to the user (step S 508 ). 
     Specifically, the CPU  111  further adds an additional charge in the case of the pre-use charging form, and adds, to the user, a charge obtained by adding an additional charge to the normal charge in the case of the post-use charging form. 
     On the other hand, in a case where the CPU  111  determines in step S 507  that the degree of contamination of the booth  80  is not high, the process is finished without performing the process in step S 508 . In this case, the charge is the normal charge. 
     As described above, in the present exemplary embodiment, the CPU  111  determines the usage fee for the booth  80  based on the behavior information of the user. 
     Specifically, the CPU  111  performs determination to increase the usage fee in a case where a behavior specified by the behavior information is a behavior of increasing the degree of infection of an infectious disease. 
     On the other hand, the CPU  111  performs determination to reduce the usage fee in a case where a behavior specified by the behavior information is a behavior of reducing the degree of infection of an infectious disease. 
       FIG. 13  is a flowchart showing a flow of processes executed by the CPU  111  in a case where the booth  80  is actually cleaned. 
     In the above description, the case where the booth  80  is cleaned after the usage time for the booth  80  is expired has been described, but the cleaning of the booth  80  may be performed during the usage time for the booth  80 . 
     In this process shown in  FIG. 13 , a process of performing cleaning during the usage time for the booth  80  will also be described. 
     In actually cleaning the booth  80 , the CPU  111  executes processes in steps  5601  to  5611  shown in  FIG. 13  every time a predefined time elapses. 
     In cleaning the booth  80 , first, the CPU  111  determines whether the booth  80  is out of the usage time (out of the reservation time) (step S 601 ). 
     In a case where the CPU  111  determines that the booth  80  is out of the usage time, the CPU  111  determines whether or not there is no user in the booth  80  based on an output from the human sensor  25  (refer to  FIG. 2 ) (step S 602 ). 
     In a case where the CPU  111  determines that there is a user in the booth  80 , the CPU  111  notifies the user in the booth  80  to leave the booth  80  via the internal speaker  30 A or the internal monitor  32  (step S 611 ). 
     On the other hand, in a case where the CPU  111  determines in step S 602  that there is no user in the booth  80 , the CPU  111  determines whether or not a predefined cleaning start time has come (step S 603 ). 
     In a case where the CPU  111  determines that the cleaning start time has come, the CPU  111  determines whether the door  22  (refer to  FIG. 2 ) is locked (step S 604 ). 
     In a case where the CPU  111  determines that the door  22  is locked, the CPU  111  starts irradiation with ultraviolet light and starts cleaning the booth  80  (step S 605 ). 
     On the other hand, in a case where the CPU  111  determines that the door is unlocked in step S 604 , the CPU  111  outputs a control signal for giving an instruction for locking the door  22  and locks the door  22  (step S 606 ). Thereafter, the CPU  111  starts cleaning the booth  80  (step S 605 ). 
     On the other hand, in a case where the CPU  111  determines in step S 601  that the booth  80  is not out of the usage time, the CPU  111  determines whether or not a switch manually operated by the user (hereinafter referred to as a “manual switch”) is turned on (step S 607 ). 
     An example of the manual switch includes a physical switch installed in the booth  80  and turned on/off by the user. In addition, an example of the manual switch includes a software switch displayed on the user terminal  4 . 
     In a case where the CPU  111  determines in step S 607  that the manual switch is not turned on, the CPU  111  determines not to perform cleaning (step S 608 ). 
     On the other hand, in a case where the CPU  111  determines in step S 607  that the manual switch is turned on, the CPU  111  provides a notification for prompting the user to leave the booth  80  via the internal monitor  32 , the internal speaker  30 A, or the like (step S 609 ). 
     Next, the CPU  111  determines whether or not there is no user in the booth  80  (step S 610 ). Specifically, the CPU  111  determines whether there is no user in the booth  80  based on an output from the human sensor  25  (refer to  FIG. 2 ). 
     In a case where the CPU  111  determines that there is a user in the booth  80 , the process in step S 609  is performed again. 
     On the other hand, in a case where the CPU  111  determines in step S 610  that there is no user in the booth  80 , the CPU  111  executes the process in step S 604 . 
     In the process in step S 604 , the CPU  111  determines whether or not the door  22  is locked as described above. In a case where the CPU  111  determines that the booth  80  is locked, the cleaning of the booth  80  is started (step S 605 ). 
     In this example, the cleaning started by turning on the manual switch is performed within the reservation time, and a user cannot use the booth  80  for the cleaning time. 
     As described above, in a case where the cleaning is performed within the reservation time, a fee for the cleaning time may not be charged. 
     Others 
     In the above description, basically, the case where the start and the end of the reservable frame is fixed has been described, but the reservable frame may be changed. 
     Specifically, in the above description, as shown in  FIGS. 14A and 14B , for example, the case where the start of the reservable frame is 00 minutes past the hour or 30 minutes past the hour and the end of the reservable frame is also the same 00 minutes past the hour or 30 minutes past the hour has been described. 
     However, there is no limitation to this, and the start or the end of the reservation frame may be changed according to a usage status for the booth  80  of a preceding user. In other words, the start or the end of the reservation frame may be changed according to a status of cleaning performed after the booth  80  is used by the preceding user. 
     In the process described above, for example, the simple cleaning mode is set, and, even in a case where a cleaning time is less than 30 minutes, such as 5 minutes or 10 minutes, 30 minutes of free time for cleaning is secured. After 30 minutes elapses, the next reservable frame is started. 
     There is no limitation to, and the start of the next reservable frame after cleaning may be changed according to a length of the cleaning performed after the booth  80  is used by the preceding user. 
     Here, for example, as shown in (A) of  FIG. 15  (a diagram for describing a change of a reservation frame), a case is assumed in which, for example, cleaning for  5  minutes is confirmed after the use of the preceding user is finished. In other words, a case is assumed in which cleaning is determined to be performed in the simple cleaning mode, and, for example, cleaning is performed for  5  minutes after the use of the preceding user is finished. 
     In this case, the start (refer to the reference sign  15 X) of a reservable frame (refer to the reference sign  15 Y) present next to a time period in which the cleaning is performed may be advanced such that the reservable frame is started earlier as shown in (B) of  FIG. 15 . 
     In this case, the CPU  111  performs a process of advancing the start of the reservable frame that is set after the cleaning time. In other words, in this case, in a case where a time for cleaning performed after the use of the preceding user is reduced, the CPU  111  performs a process of advancing the start of the reservable frame that is set after the cleaning. 
     In this example, a process of advancing the end of the reservable frame is also performed. 
     In this example, the starts and the ends of other reservable frames after this reservable frame (the reservable frame indicated by the reference sign  15 Y) are also advanced. 
     In a case where the process is performed, a situation in which the booth  80  becomes free and the booth  80  is not used even though the cleaning has been completed can be avoided. 
     In addition, a time period after a reservation time period (reservable frame) for which a reservation is made is not necessarily a free time period, and the free time period need not be secured depending on a reservation status. 
     In the present exemplary embodiment, as indicated by the reference sign  14 B in  FIG. 14A , a process in which reservations are not continuously made is performed, and thus a free time period for which a reservation is not made is secured between reservation time periods that precede and succeed temporally. 
     There is no limitation to this, this free time period need not be secured depending on a reservation status. 
     Specifically, for example, as indicated by the reference sign  14 X in  FIG. 14A , in a case where a plurality of consecutive reservation time periods are reserved by a common (same) user, free time period for the above cleaning need not be secured in the plurality of reservation time periods. 
     In a case where the booth  80  is used by a common user, infection between different users does not occur, and thus spread of an infectious disease can be suppressed without securing a cleaning time. 
     In other words, in a case where each of a plurality of temporally consecutive reservable frames is reserved by a common user, the CPU  111  permits this reservation. In this case, the above free time period is not secured, but the spread of an infectious disease can be suppressed without this free time period. 
     On the other hand, in a case where the plurality of temporally consecutive reservable frames are respectively reserved by different users, the CPU  111  does not permit a reservation for each of the plurality of temporally consecutive reservable frames. 
     In this case, after a certain user uses the booth  80 , a free time is secured, and another user uses the booth  80  after the free time. 
     Each configuration described above is not limited to the above-described exemplary embodiment and the modification thereof and can be changed without departing from the spirit. In other words, it is understood that various changes in form and details are possible without departing from the purpose and scope of the claims.
