Description

  The present invention relates to a management system that manages the use of devices to be managed such as electronic devices and equipment provided in a room in a facility where entry is managed.

  When an operator uses an electronic device or facility in a predetermined room, it may be a condition that the administrator is in the room from the viewpoint of preventing information leakage. In this case, in order for an operator to use an electronic device or facility, “the administrator who entered the room must make the electronic device or facility available” or “when the operator uses the electronic device or facility, "When the administrator uses the electronic device or facility, the operator receives a medium for making the electronic device or the like available from the administrator, and the operator makes the electronic device or the like available." Is set to a state where the electronic device or the like can be used. Similarly, in order to stop the use of an electronic device or facility, a method such as “the administrator puts the electronic device or facility into a use stop state” is used.

  However, in the conventional method, in order to make an electronic device or facility available or in a suspended state, it is necessary for the administrator himself to deal with it each time. For this reason, there have been problems that the administrator forgets to make it available, and the management of the medium that can be used is troublesome. Further, when the number of electronic devices and facilities is large, there has been a problem that a great burden is imposed on the administrator.

  On the other hand, a security technique using an information storage medium such as an IC card has already been known as a security technique for preventing unauthorized use of a computer by a third party who does not have the use authority. In one example, when a computer is used, identification information is read from an information storage medium such as an IC card in which identification information for authenticating the person in advance is stored, and the person is identified by a matching process based on the read identification information. When authentication is performed and the authentication is established, the computer can be used (see, for example, Patent Documents 1 and 2).

The facility in the present invention includes, for example, a room, a building, a floor in a building, a specific place, a specific area, a specific area, a specific area, and the like. In the description of the present embodiment, an electronic apparatus is given as an example. Describe the room equipped with.

  The personal computer 50, which is an electronic device provided in the room 4, can be used by the operator 2 only while the administrator 1 having authority to manage the electronic device is present in the room. The manager 1 has the right to enter the room 4 and the right to manage the personal computer 50, and has a non-contact IC card 3a that is an information storage medium. On the other hand, the operator 2 has the right to enter the room 4 and has a non-contact IC card 3b which is an information storage medium. The non-contact IC card 3 includes both the non-contact IC cards 3a and 3b.

  An entrance management device 6 is provided in the vicinity of the entrance 5a of the room 4. The entrance management device 6 controls the open / close state of the automatic door 7 provided at the entrance 5a. The room entrance management device 6 is configured to be able to transmit information wirelessly to and from the non-contact IC card 3 and can read information stored in the non-contact IC card 3. Further, an exit management device 10 is provided in the vicinity of the outlet 5b of the room 4, and the open / close state of the automatic door 7 is controlled by the exit management device 10. Further, the leaving management apparatus 10 is configured to be able to transmit information wirelessly to and from the non-contact IC card 3 and can read information stored in the non-contact IC card 3. That is, in this embodiment, the non-contact IC card 3 is used as access control for entering and leaving the room.

  In addition, there are a case where the entrance 5a and the exit 5b are separately provided in the room 4, and a case where the entrance 5a and the exit 5b are combined as one entrance, but FIG. 1 shows a case where one entrance is used. It is shown. Further, the entrance / exit management device 6 and the exit management device 10 may be integrated into a single unit, and may be provided on a part of the wall separating the outside and the inside of the room. Here, the entrance / exit management device is, for example, an IC card reader / writer that can read information from the non-contact IC card 3 and write information to the non-contact IC card 3.

  The personal computer 50 includes an IC card reader / writer 9. The IC card reader / writer 9 can read information from the non-contact IC card 3 and write information to the non-contact IC card 3 in the same manner as the entrance / exit management device.

  For example, as shown in FIGS. 2 to 4, the non-contact IC card 3 as an information storage medium has a configuration in which a non-contact IC tag 8 is built in card bases 30 and 31. The non-contact IC tag 8 is also referred to as, for example, a non-contact data carrier or RFID, and as shown in FIG. 4, a transmission / reception unit 88 formed of a coil pattern is formed on a base material 81 such as plastic. The non-contact IC tag 8 receives and transmits a radio wave having a constant frequency by forming a resonance circuit with a coil and a capacitive element. As another method, power transmission and data transmission may be performed by electromagnetic induction of a carrier wave from a reader / writer. Generally, a frequency band of 135 kHz (medium wave), 13.56 MHz, and 2.45 GHz (microwave) is used.

  In the case of the illustrated example, the transmitting / receiving unit 88 formed of a coil pattern forms a jumping circuit on the back surface of the base material 81 by the conductive member 84 and is connected to the bumps on the back surface of the IC chip 82 by the coil connection terminals 88C. The IC chip 82 includes a control unit 89 that is a CPU and a storage unit 90 that is a memory.

  In the illustrated example, the capacitive element is built in the IC chip 82. Such a non-contact IC tag 8 is formed by forming a coil pattern by photo etching or etching after resist printing on a metal foil such as an aluminum foil laminated on a resin base material, mounting an IC chip 82, and for protection. It is formed by providing a coating. The size can also be set to about 30 mm × 30 mm or less.

  As the resin base material 81 used for the non-contact IC tag 8, various materials such as PET, polypropylene, polyethylene, polystyrene, and nylon can be used, and paper may be used. Although thickness can be 15-300 micrometers, 20-100 micrometers is more preferable from points, such as intensity | strength, workability | operativity, and cost. Although copper foil, aluminum foil, or iron foil can be used as the metal foil, aluminum foil is preferable from the viewpoint of cost and workability, and the thickness is preferably about 6 to 50 μm.

  In reading and writing information recorded on these non-contact IC tags 8, a calling signal that resonates from the IC card reader / writer 9 to the non-contact IC tag 8 is transmitted at a distance of several centimeters to several tens of centimeters. The response signal from the non-contact IC tag 8 is read. Thereby, the information recorded in the memory which is a memory | storage part of IC chip 82 of the non-contact IC tag 8 can be read, or information can be written. In addition, ID information (identification information) for authenticating the person himself / herself is registered in advance in a memory that is a storage unit of the IC chip 82.

  Next, the system configuration will be described in detail with reference to the functional block diagram of FIG. FIG. 5 shows a system configuration including the non-contact IC card 3, the entrance / exit management device, the IC card reader / writer 9, and the personal computer 50.

  The entry / exit management device in the block diagram of FIG. 5 is an apparatus in which the entrance management device 6 and the exit management device 10 in FIG. 1 are integrated. In the present embodiment, it is assumed that there is one manager for each room and a plurality of operators.

  The entrance / exit management device provided in the vicinity of the entrance / exit 5 includes a transmission / reception unit 11, an authority determination unit 12, a door opening / closing unit 13, a storage unit 14, an entrance information writing unit 15, and a control unit 16. Each unit is controlled by the control unit 16.

  The transmission / reception unit 11 transmits and receives information wirelessly with the transmission / reception unit 88 of the non-contact IC card 3.

  Based on the identification information received from the non-contact IC card 3 at the time of entry / exit and the authority table stored in the storage unit 14 in advance, the authority determination unit 12 can enter the room. It is determined whether the user has authority. Further, the authority determination unit 12 determines whether the person possessing the non-contact IC card is based on the identification information received from the non-contact IC card 3 at the time of entering or leaving the room and the authority table stored in the storage unit 14 in advance. It is determined whether or not the user has administrative authority.

  Here, the authority table stored in the storage unit 14 will be described with reference to FIG. FIG. 6 is a diagram schematically showing the data structure of the authority table. In the present embodiment, the contactless IC card 3 includes an employee ID as identification information.

  As shown in the figure, the authority table is composed of items of employee ID, room entry authority, and management authority. The employee ID is information for identifying each user such as an administrator or an operator. The entry authority is an authority to enter the room 4, and a circle (◯) is stored in the entry authority item corresponding to the employee ID having the entry authority in the authority table. The management authority is an authority capable of managing the personal computer 50 in the room 4. In the authority table, a circle (◯) is stored in the management authority item corresponding to the employee ID having the management authority. The operator can use the personal computer 50 only while an administrator having management authority is in the room 4. The authority determination unit 12 refers to the authority table based on the identification information read from the non-contact IC card, that is, the employee ID, so that the person who owns the non-contact IC card has the authority to enter the room and / or the management authority. It can be easily determined whether or not.

  When it is determined by the processing by the authority determining unit 12 that the person who has the non-contact IC card 3 has the authority to enter the room when entering or leaving the door, the door opening / closing unit 13 opens the automatic door 7. Further, when it is determined by the processing by the authority determination unit 12 that the person who has the non-contact IC card has the management authority when entering the room, the storage unit 14 stores the room entry information indicating that the administrator has entered the room. To remember.

  The entrance information writing unit 15 is a case where it is determined by the processing by the authority determining unit 12 that an operator having only the entrance authority has entered the room, and the entrance information is stored in the storage unit 14. The room entry information is transmitted to the non-contact IC card 3b possessed by the operator, and the room entry information is written in the storage unit 90 of the non-contact IC card 3b.

  The room entry information is information indicating that the manager has entered the room 4, and the data format can be arbitrarily set. For example, an entry flag storage area may be provided in the storage unit 90 of the non-contact IC card 3, and a flag may be written as entry information when entering the entry flag storage area. Alternatively, the flag may be written in the room entry flag storage area in advance, and the flag written at the time of entering the room may be erased so that the manager can determine that the room has been entered. . When the above flag is used, the information stored in the entry flag storage area is changed by writing or erasing the flag in the entry flag storage area. Thus, the entry information is written.

  In the present embodiment, the data structure of the authority table stored in the storage unit 14 is as shown in FIG. 6, but the present invention is not limited to this, and is read from the non-contact IC card 3. If the presence / absence of room entry authority and management authority can be determined based on the identification information, the data structure can be arbitrarily set.

  The personal computer 50 includes a display unit 21, an entrance determination unit 22, a personal computer lock control unit 23, a storage unit 24, an input unit 25, an interface (I / F) 26, and a control unit 27. Each unit is controlled by the control unit 27.

  The entrance determination unit 22 transmits a signal from the IC card reader / writer 9 to the non-contact IC card 3. In this way, the information stored in the storage unit 90 of the non-contact IC card 3 is read, and it is determined whether or not the entry information is included in the information. If the room entry information stored in the non-contact IC card 3 indicates the presence or absence of a flag, the room entry determination unit 22 determines whether or not the administrator has entered the room 4 based on the presence or absence of the flag. .

  When it is determined that the entry information is included in the information read from the non-contact IC card 3, the personal computer lock control unit 23 releases the lock of the personal computer 50 and controls it to be usable. Further, when the non-contact IC card 3 is removed from the IC card reader / writer and the use of the personal computer 50 is finished, the personal computer 50 is locked and controlled so that it cannot be used.

  In the present embodiment having the above configuration, the room 4 corresponds to a facility, and the entrance / exit management device functions as an entrance / exit management device. In addition, the personal computer 50 functions as a management target device.

  Next, room entry processing by the above management system will be described with reference to FIG. FIG. 7 is a flowchart of the room entry process.

  First, when entering the room 4 which is a facility where entry is managed, the administrator or operator who is a user enters and exits the non-contact IC card 3 which is an information storage medium in order to enter the room 4 from the entrance. Move closer to the management device. At this time, the entrance / exit management device reads the employee ID stored in the storage unit 90 of the non-contact IC card 3 (step S1). The authority determination unit 12 of the entry / exit management device allows the person who has the non-contact IC card 3 to enter the room based on the read employee ID and the authority table registered in advance in the storage unit 14 of the entry / exit management device. It is determined whether the user has authority (step S2). If the user does not have entry authority (step S2; No), the process ends without opening the automatic door 7. On the other hand, if the user has authority to enter the room (step S2; Yes), the authority determination unit 12 further determines whether the person who owns the non-contact IC card 3 has management authority (step S3). .

  When it has the management authority (step S3; Yes), the entry information indicating that the administrator has entered the room 4 is stored in the storage unit 14 (step S4). Then, the door opening / closing unit 13 opens the automatic door 7 so that an administrator having authority to enter the room can enter the room 4 (step S5).

  On the other hand, if the user does not have management authority (step S3; No), it is determined whether or not the room entry information is stored in the storage unit 14 (step S6). When the entry information is not stored (step S6; No), the door opening / closing unit 13 opens the automatic door 7 so that an operator having entry authority can enter the room 4. On the other hand, when the room entry information is stored (step S6; Yes), the room entry information writing unit 15 transmits the room entry information to the non-contact IC card 3b and enters the storage unit 90 of the non-contact IC card 3. Information is written (step S7). Then, the door opening / closing part 13 opens the automatic door 7 so that an operator having entry authority can enter the room 4 (step S5). This completes the room entry process.

  The operator who enters the room from the entrance brings the non-contact IC card 3b close to the IC card reader / writer 9 provided in the personal computer 50, and the IC card reader / writer 9 reads information from the storage unit 90 of the non-contact IC card 3b. The room entry determination unit 22 determines whether or not room entry information is included in the information read from the storage unit 90 of the non-contact IC card 3b. Here, when it is determined that the room entry information is included, the personal computer lock control unit 23 releases the lock of the personal computer 50 so that the personal computer 50 can be used. That is, the operator can use the personal computer 50. On the other hand, when it is determined that the room entry information is not included, the lock of the personal computer 50 is not released and the operator cannot use the personal computer 50.

  Thereby, when an administrator enters the room 4, the personal computer 50 can be automatically used without any special action by the administrator. Therefore, the burden on the administrator can be reduced.

  In the present embodiment, the non-contact IC card 3 is used, but the present invention is not limited to this, and a mobile phone equipped with an information storage medium may be used. That is, in the present invention, any portable storage medium can be applied as long as it can be used as access control for entering and leaving the room.

  In the present embodiment, the non-contact IC card 3 has only identification information, and the entrance / exit management device refers to the authority table based on the read identification information, so that the presence / absence of entry authority and management authority is determined. Is going to be judged. However, the present invention is not limited to this, and the non-contact IC card 3 may have information indicating presence / absence of entry authority and management authority. Specifically, the contactless IC card 3a possessed by the manager includes information (flags, etc.) indicating that there is authority to enter the room and management, and the contactless IC card 3b possessed by the operator Information indicating that the user has authority is included. In this case, the entrance / exit management device does not need to register an authority table in advance, and determines whether there is an entrance authority and management authority based on information read from the non-contact IC card.

  In this embodiment, a personal computer is described as an example of a management target device. However, the present invention is not limited to this, and may be applied to any electronic device or facility other than a personal computer such as a printer or a locker. Can do.

[First modification]
Although not described in the above embodiment, the usage range information can be stored in advance in the non-contact IC card 3b possessed by each operator. Here, the usage range information will be described with reference to FIG. FIG. 8 is a diagram illustrating a data structure of usage range information. As shown in the figure, the usage range information is composed of a type item and an available number of times item. The type item is information indicating the type of the management target device. In this modification, for example, a locker, a scanner, a printer, or the like is used. The useable number item is the number of times that the operator can use. The usage range information can be arbitrarily set for each operator as shown in FIGS. 8 (a) and 8 (b). For example, in the case of an operator having the non-contact IC card 3b in which the user range information A shown in FIG. 8A is stored, the printer cannot be used even when the manager is in the room 4. . On the other hand, in the case of an operator having the non-contact IC card 3b in which the user range information B shown in FIG. 8B is stored, the printer can be used up to 10 times when the administrator is in the room 4. .

  In this case, the entrance / exit management device effectively sets the use range information stored in the non-contact IC card 3b of the operator, instead of writing the entrance information to the non-contact IC card 3b of the operator in the above-described entrance processing. In other words, the usage range information stored in the contactless IC card 3b of the operator is set to invalid in the initial state, and is valid by the entrance / exit management device only when the administrator enters the room 4. Is set.

  Further, the management target device stores information on the type and number of times used by the operator in its own storage unit. Then, the management target device refers to the storage unit based on the type, and determines whether or not the number of times the operator has used is within the number of times that the usage range information can be used. When it is determined that the number of times of use is less than the number of times of use, that is, within the number of times of use, a state in which the managed device can be used by unlocking the managed device of that type by the lock control unit And That is, the operator can use the management target device. On the other hand, when it is determined that the number of times of use is greater than the number of times of use, that is, not within the number of times of use, the operator cannot use the managed device without unlocking the managed device. .

  Here, use processing by the management system of the first modification will be described with reference to FIG. FIG. 9 is a flowchart of the usage process.

  The operator who enters the room from the entrance brings the non-contact IC card 3b close to the IC card reader / writer 9 provided in a predetermined management target device selected from the printers and scanners installed in the room 4. The IC card reader / writer 9 connected to the management target device reads information from the storage unit 90 of the non-contact IC card 3b. The managed device determines whether the setting of the usage range information included in the information read from the storage unit 90 of the non-contact IC card 3b is valid (step S11). When it is determined that the setting is invalid (step S11; No), the management target device ends the use process.

  On the other hand, when it is determined that the setting is valid (step S11; Yes), the management target device matches the type of the type item constituting the usage range information read from the non-contact IC card 3b. It is determined whether or not (step S12). If they do not match (step S12; No), the management target device ends the use process. On the other hand, if they match (step S12; Yes), the management target device refers to the storage unit, and whether the usage count of the management target device by the operator is within the usage count of the type items constituting the usage range information. It is determined whether or not (step S13). When it is not within the number of times of use (step S13; No), the management target device ends the use process.

  If it is within the available number of times (step S13; Yes), the lock is released and the managed device is controlled to be usable (step S14). In addition, the management target device updates the number of times the operator has used the management target device in the storage unit (step S15). Thereby, the use process is completed.

  In the first modification described above, the usage range information has a data structure as shown in FIG. 8, but the present invention is not limited to this and can be arbitrarily set. For example, it is possible to set an effective time and an effective date and time as the usage range information, and to limit the use of the management target device based on the time and date since the operator entered the room 4.

  According to this, the use of the management target device can be restricted within a range corresponding to each operator based on the use range information. Therefore, even if the manager leaves the room 4, the problem that the operator can use the management target device without restriction can be solved.

[Second modification]
Although not described in the above embodiment, the entrance / exit management device and the management target device can be connected to be communicable via a network.

  FIG. 10 shows an outline of a management system that manages the management target device in the second modification. In addition, about the part similar to the above-mentioned embodiment, description is abbreviate | omitted for convenience.

Here, the entrance / exit management device is, for example, an IC card reader / writer that can read information from the non-contact IC card 3 and write information to the non-contact IC card 3.

  The personal computer 150 is provided with an IC card reader / writer 9. The IC card reader / writer 9 can read information from the non-contact IC card 3 and write information to the non-contact IC card 3 in the same manner as the entrance / exit management device.

  Next, the system configuration will be described in detail with reference to the functional block diagram of FIG. FIG. 11 shows a system configuration including the non-contact IC card 3, the entrance / exit management device, the IC card reader / writer 9, and the personal computer 150.

  The entry / exit management device in the block diagram of FIG. 11 is an apparatus in which the entrance management device 6 and the exit management device 10 in FIG. In the present embodiment, it is assumed that there is one manager for each room and a plurality of operators.

  The entrance / exit management device provided in the vicinity of the entrance / exit 5 includes a transmission / reception unit 11, an authority determination unit 12, a door opening / closing unit 13, a storage unit 14, an entrance information writing unit 15, a control unit 16, and a communication unit 17. Yes. Each unit is controlled by the control unit 16.

  The transmission / reception unit 11 transmits and receives information wirelessly with the transmission / reception unit 88 of the non-contact IC card 3.

  Based on the identification information received from the non-contact IC card 3 at the time of entry / exit and the authority table stored in the storage unit 14 in advance, the authority determination unit 12 can enter the room. It is determined whether the user has authority. Further, the authority determination unit 12 determines whether the person possessing the non-contact IC card is based on the identification information received from the non-contact IC card 3 at the time of entering or leaving the room and the authority table stored in the storage unit 14 in advance. It is determined whether or not the user has administrative authority. Furthermore, when the authority determination unit 12 determines that the person who has the non-contact IC card has the management authority when leaving the room, the exit information is transferred from the entrance / exit management device to the personal computer 150 via the communication unit 17. Send.

  When it is determined by the processing by the authority determining unit 12 that the person who has the non-contact IC card 3 has the authority to enter the room when entering or leaving the door, the door opening / closing unit 13 opens the automatic door 7. Further, when it is determined by the processing by the authority determination unit 12 that the person who has the non-contact IC card has the management authority when entering the room, the storage unit 14 stores the room entry information indicating that the administrator has entered the room. To remember.

  The entrance information writing unit 15 is a case where it is determined by the processing by the authority determining unit 12 that an operator having only the entrance authority has entered the room, and the entrance information is stored in the storage unit 14. The entrance information is transmitted to the non-contact IC card 3b possessed by the operator, and the entrance information is written in the storage unit 90 of the non-contact IC card 3.

  The personal computer 150 includes a display unit 21, an entrance determination unit 22, a personal computer lock control unit 23, a storage unit 24, an input unit 25, an interface (I / F) 26, a control unit 27, an exit determination unit 28, and a communication unit 29. ing. Each unit is controlled by the control unit 27.

  The entrance determination unit 22 transmits a signal from the IC card reader / writer 9 to the non-contact IC card 3. In this way, the information stored in the storage unit 90 of the non-contact IC card 3 is read, and it is determined whether or not the entry information is included in the information. If the room entry information stored in the non-contact IC card 3 indicates the presence or absence of a flag, the room entry determination unit 22 determines whether or not the administrator has entered the room 4 based on the presence or absence of the flag. .

  The leaving determination unit 28 determines that the manager has left the room 4 when receiving the leaving information from the entry / exit management device via the communication unit 29.

  When it is determined that the room entry information is included in the information read from the non-contact IC card 3 by the room entry determination unit 22, the personal computer lock control unit 23 releases the lock of the personal computer 150 and controls it to be usable. . Further, when the non-contact IC card 3 is removed from the IC card reader / writer and the use of the personal computer 150 is terminated, the personal computer 150 is locked and controlled so that it cannot be used.

  Further, the personal computer lock control unit 23 locks the personal computer 150 when the exit determination unit 28 receives the exit information from the entrance / exit management device and determines that the manager has exited the room 4, and the personal computer lock control unit 23 cannot use the personal computer. To control.

  Next, the leaving process by the above management system will be described with reference to FIG. FIG. 12 is a flowchart of the leaving process.

  When leaving the room 4 which is a facility where entry / exit is managed, the manager or operator who is a user enters / exits the non-contact IC card 3 which is an information storage medium in order to leave the exit of the room 4 Move closer to the device. At this time, the entrance / exit management device reads the employee ID stored in the storage unit 90 of the non-contact IC card 3 (step S21). The authority determination unit 12 of the entrance / exit management device is managed by a person who possesses the non-contact IC card 3 based on the read member ID and the authority table registered in advance in the storage unit 14 of the entrance / exit management device. It is determined whether the user has authority (step S22).

  If the user has management authority (step S22; Yes), the exit information indicating that the manager has left the room 4 is transmitted to the personal computer 150 via the communication unit 17 (step S23). When the communication unit 29 receives the exit information from the entrance / exit management device, the management target device determines that the administrator has exited the room 4 by the exit determination unit 28. Therefore, the personal computer lock control unit 23 locks the personal computer 150 so that it cannot be used. When the entrance / exit management device transmits the exit information to the personal computer 150, the door opening / closing unit 13 opens the automatic door 7 so that the manager can exit the room 4 (step S24).

  On the other hand, if the user does not have management authority (step S23; No), the entrance / exit management device opens the automatic door by the door opening / closing unit 13 without transmitting the exit information to the personal computer 150, and the operator leaves the room 4. A possible state is set (step S24). Thereby, the leaving process is completed.

  According to this, when the administrator leaves the room 4, the use of the personal computer 150 by the operator can be stopped. Therefore, the problem that the operator can continue to use the personal computer 150 even though the manager leaves the room 4 can be solved. Further, when the manager leaves the room 4, the personal computer 150 cannot be used automatically without any special action by the manager. Therefore, the burden on the administrator can be reduced.

  In the second modification, the personal computer 150 directly receives the exit information from the entrance / exit management device and determines whether or not the administrator has exited the room 4 and then controls the lock of the personal computer 150. However, the present invention is not limited to this, and may be connected to a server via the network 60, and the server may control the lock of the personal computer 150. In this case, in the management system, the entrance / exit management device, the personal computer 150, and the server are communicably connected via the network 60. The entrance / exit management device transmits exit information to the server 5 via the network 60, and the server 5 determines whether or not the administrator has exited the room 4 based on the exit information, and then the personal computer 150 Control the lock. Specifically, when it is determined that the manager has left the room 4, the PC 150 is made unusable by transmitting a predetermined signal to the PC 150 via the network 60.

  In this way, by using the server as a component of the management system, it is possible to apply various electronic devices and equipment that cannot be used to determine whether the administrator 4 has left the room or to perform lock control. Become.

  Further, although not described in the above-described embodiment, the first modified example, and the second modified example, the entry / exit management device stores the information when it is determined that the manager has left the room as described in the second modified example. When the entrance information is deleted from the unit 14, the entrance information may be deleted from the IC card 3b possessed by the operator who leaves the room. Specifically, the entry / exit management device determines whether or not entry information is stored in the storage unit 14 when an operator having only entry authority leaves the room. When the entry information is not stored in the storage unit 14 and the entry information is stored in the IC card 3b possessed by the operator, the entry / exit management device is stored in the IC card 3b. Delete the entry information. Thereby, even if the operator enters the room 4 again, the management target apparatus cannot be used if the manager is absent.

  Further, as in the second modification, when the entrance / exit management device and the management target device are communicably connected via the network 60, the management target device that has received the exit information is controlled by the IC card reader / writer 9 using the IC card reader / writer 9. It may be possible to delete the room entry information from the card 3b or to make the use range information invalid.
