Description

  The present invention relates to a locking / unlocking system, a portable terminal, a key opening / closing device, a locking / unlocking method, a locking / unlocking instruction program, a locking / unlocking processing program, and a program recording medium.

  Japanese Patent Application Laid-Open No. 2006-119947 disclosed in Japanese Patent Application Laid-Open No. 2006-119947, Japanese Patent Application Laid-Open No. 2008-133635, Japanese Patent Application Laid-Open No. 2008-133635, “Entrance / Exit Management System, Facility, and Security System” As described in Japanese Patent No. 138467, “Electric Lock System”, etc., there is already a lock / unlock system using an authentication function of a non-contact IC tag equipped in a portable terminal, but an identification number unique to the portable terminal is used. Therefore, prior registration is required for the locking and unlocking system. Pre-registration such as this, when an authorized unspecified number of people intends to lock or unlock the key, the unspecified number of all members must be registered in advance, and the increase or decrease in the number of permitted persons Every time there is a registration or deletion work is required. Such a locking / unlocking system can maintain a high level of security, but also hinders easy use and is complicated with management work.

  In addition, in the case of a key that is locked with a combination of numerical symbols as a personal identification number, if the numerical value corresponding to the personal identification number or the number of digits of the symbol increases, problems such as being unable to memorize, and errors will occur at the time of memo transcription and input There's a problem. On the other hand, since reducing the number of digits of the password is likely to be unlocked by a brute force attack by a malicious third party, it is essential to set the number of digits greater than a certain number.

  Also, instead of using a preset fixed number as the security code, the number or number of digits can be changed or the user can set an arbitrary number, or not only a specific individual but also an unspecified number In the situation where no effective mechanism exists as a means to accurately and reliably and promptly notify the PIN when the person shares the number or when the locker and unlocker are different is there.

JP 2006-119947 A (pages 10-12) JP 2008-133635 A (page 7-9) JP 2008-138467 A (page 6-7)

  As described above, there has been a problem with the lock / unlock system using the authentication function of the conventional non-contact IC tag.

  The present invention has been made in view of such circumstances, and an object of the present invention is to make it easy and reliable for button operation when manually entering password information without requiring prior registration for personal authentication. While maintaining this mechanism, it is possible to accurately lock and unlock any key using a short-range communication function such as a non-contact IC tag and the security code used at that time. It is another object of the present invention to provide a mechanism for notifying an unlocker who needs an unlocking operation reliably and quickly.

  In order to solve the above-described problems, the locking and unlocking system according to the present invention employs the following characteristic configuration.

  (1) A locking / unlocking system that opens and closes a key in a key opening / closing device using password information, and includes a password information input means for inputting the password information to the key opening / closing device and a device-side communication means for performing short-range communication. And a terminal-side communication means for performing near field communication with the device-side communication means of the key opening / closing device in the user's portable terminal, and the key is received by the password information input from the password information input means by the user. A locking / unlocking system that opens and closes and transfers the entered password information to the portable terminal possessed by the user via the device-side communication means when the key is locked.

  According to the locking / unlocking system, portable terminal, key opening / closing device, locking / unlocking method, locking / unlocking instruction program, locking / unlocking processing program, and program recording medium of the present invention, the following effects can be achieved.

  The first effect is that the personal identification information (for example, the personal identification number) is not locked as the personal identification information (for example, the personal identification number) of the portable terminal (for example, the personal identification number) as the personal identification information (for example, the personal identification number) for locking and unlocking the key. Since a mechanism is used that is arbitrarily set by a user and transferred to another person (unlocker) who needs an unlocking operation as necessary, the key of the key opening / closing device and the portable terminal (for example, a cellular phone) ) Etc. need not be registered in advance. Therefore, the lock and unlock system of the present invention can be used universally with any key and any portable terminal without prior registration.

  The second effect is that, in a key opening / closing device of a password information input method, an unlocker can be provided without directly inputting password information (for example, a password number) to a password information input device (for example, a password number input device). PIN information (for example, a PIN number) previously transferred to a portable terminal (for example, a mobile phone) can be input using a short-range communication function (for example, a communication function for a non-contact IC tag). When unlocking, there is no longer any wobbling or mistake when inputting the password information (for example, the password) to the key opening / closing device. Therefore, the staying time in front of the key opening / closing device can be shortened. That is, the key opening / closing device can be unlocked quickly. In addition, since arbitrarily set password information can be recorded on the locker's mobile terminal (for example, a mobile phone) each time it is locked, even if the password information is changed every time the locker himself / herself is locked, It is not necessary to memorize, and it can be unlocked reliably using a mobile terminal (for example, a mobile phone) at the time of unlocking.

  As a third effect, as a method of notifying the unlocking person other than the locker himself / herself the password information (for example, the password) determined at the time of locking, a portable terminal (for example, a mobile phone) owned by the locker or the unlocker is used. The personal identification information (for example, a personal identification number) can be notified using a communication function between portable terminals (for example, an electronic mail (E-Mail) function) provided in the personal computer. Therefore, the unlocker who is notified of the personal identification information (for example, personal identification number) can perform unlocking as quickly as the unlocker. Further, it is possible to have a feature that the unlocking person can be limited every time the locking is performed.

It is a system configuration figure showing an example of the system configuration of the locking unlocking system concerning the present invention. It is a flowchart which shows an example of operation | movement of the locking / unlocking system shown in FIG. It is a flowchart which shows the example different from FIG. 2 of operation | movement of the locking / unlocking system shown in FIG.

  Preferred embodiments of a locking / unlocking system, portable terminal, key opening / closing device, locking / unlocking method, locking / unlocking instruction program, locking / unlocking processing program, and program recording medium according to the present invention will be described below with reference to the accompanying drawings. To do. In the following description, a locking / unlocking system, a portable terminal, a key opening / closing device, and a locking / unlocking method according to the present invention will be described. The locking / unlocking method can be executed by a computer on the portable terminal side. It may be implemented as an instruction program, a locking / unlocking processing program program that can be executed by a computer on the key opening / closing device side, or a computer-readable recording of each of the locking / unlocking instruction program and the locking / unlocking processing program Needless to say, it may be recorded on a medium.

  In the following description, a case where a communication method using a non-contact IC (Integrated Circuit) tag is used as an example of a short-range communication between the portable terminal and the key opening / closing device will be described. The present invention is not limited to this, and any communication method may be used as long as it is a communication method capable of performing near field communication. Further, as a portable terminal with a built-in or external contactless IC tag as described above for short-distance communication, a mobile phone will be described as an example. However, the present invention is not limited to a mobile phone. (Personal Handy-Phone System) terminal, PDA (Personal Digital Assistants: portable information terminal), portable notebook PC (Personal Computer), or any other portable terminal with a built-in or external contactless IC tag. It doesn't matter.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be described first. The present invention relies on human memory and transcription to a memo in a locking / unlocking system that unlocks a key by inputting the same password information as the combination of numerical values and symbols set as the password information when the key is locked. First, a mechanism for exchanging information about locking / unlocking with a key opening / closing device using a communication function of a near field communication function such as a non-contact IC (Integrated Circuit) tag equipped in a mobile terminal such as a mobile phone, Communication information between mobile terminals, such as e-mail (E-Mail), etc., accurately and reliably and promptly transmit the password information to the other party (unlocker) who needs the unlocking operation. It is characterized by having a mechanism to do. That is, the present invention does not use a short-range communication function, for example, a unique authentication function normally provided in a non-contact IC tag, but directly unlocks and locks by the authentication function itself as a non-contact IC tag. Is not specified. In other words, the present invention defines a mechanism for inputting numerical values, characters, and symbols as password information, and a mechanism for exchanging and communicating with unlockers who need the password information.

  That is, the present invention has the following mechanism for locking and unlocking a key.

(Locking mechanism)
In the case of locking through a non-contact IC tag incorporated in a mobile terminal (such as a mobile phone, a PHS terminal, a PDA or a personal computer) having a communication function or linked by an external device, the password information (numerals, characters, symbols, theirs) A mechanism for reading and confirming (combination) or writing and confirming, and further, an operation for transmitting the confirmed personal identification information (numbers, letters, symbols, and combinations thereof) to the unlocker who needs it. And a mechanism that automatically performs communication means such as electronic mail (E-Mail).

  Here, the reading and confirmation of the password information means that the information entered as the password information (numbers, characters, symbols, combinations thereof) by the password information input device (for example, the password number input device) on the key opening / closing device side, This means that when it is transferred to a portable terminal via a non-contact IC tag built in or externally attached to the personal identification information, the personal identification information is confirmed for key opening / closing and locked. In addition, writing and confirmation of a personal identification number is a key for inputting information entered as personal identification information (numbers, characters, symbols, and combinations thereof) on the mobile terminal side via a non-contact IC tag built in or externally attached to the mobile terminal. When transferred to the switchgear, it means that locking is performed with the password.

(Unlocking mechanism)
The unlocker (including the locker himself / herself) receives the communication information by the e-mail (E-Mail) etc. from the locker by the communication means such as e-mail (E-Mail). Security information (numbers, letters, symbols, combinations thereof) for locking / unlocking can be received. Unlocking the key opening / closing device by transferring the received password information to the target key opening / closing device using a non-contact IC tag incorporated in or externally attached to the portable terminal that is the receiving terminal of the unlocker. Can do.

  In other words, the personal identification information is not communicated with the key opening / closing device as an authentication function using an identification number unique to the mobile terminal of the receiving terminal, but the information received as a signal equivalent to the key number pressing by normal manual input is used. To communicate with the key opening / closing device. For this reason, a signal converter is introduced into the key opening / closing device. The key opening / closing device unlocks when the information obtained by converting the received signal matches the password information previously set at the time of locking.

  However, it may be a case where the personal identification information is manually input via a conventional personal identification information input device (for example, a number input device), and the personal identification information is input by the personal identification information transfer function according to the present invention. No distinction is made between the input process and the input process. Further, for example, information that is one digit less than the number of digits required by the key opening / closing device is set and transferred to the key opening / closing device by the information transfer function, and only the last digit is manually input to the key opening / closing device. It is also acceptable.

(Configuration example of embodiment)
Next, an example of the system configuration of the locking and unlocking system according to the present invention will be described with reference to FIG. FIG. 1 is a system configuration diagram showing an example of a system configuration of a locking / unlocking system according to the present invention. In FIG. 1, the mobile terminals possessed by the locker and the unlocker are mobile phones 10 and 20, respectively, and the communication means for exchanging information between the mobile phones 10 and 20 via the mail server 40. A personal identification number consisting of numerical information is used as personal identification information (numerals, characters, symbols, or a combination thereof) that is an electronic mail (E-Mail) and is used for locking / unlocking the key of the key opening / closing device 30. Explains the case. In addition, as a short-range communication method for transmitting and receiving password information (numbers, characters, symbols, or a combination thereof) between the mobile phones 10 and 20 and the key opening / closing device 30, a communication method using a non-contact IC tag is used. The case where it uses is shown.

  The lockable mobile phone 10 has a non-contact IC tag 11 as a terminal-side communication means for near field communication for transmitting / receiving a password used for locking the key as a password signal to / from the key opening / closing device 30. It is mounted (whether internal or external). Also, a key exchange function 12 for controlling a password transmitted / received to / from the key opening / closing device 30 and the cellular phone 20 on the unlocker side, and a function for transmitting the password to the cellular phone 20 on the unlocker side. The personal identification number transmission / reception function 13 (email function or the like) is incorporated.

  On the other hand, similarly to the cellular phone 10 on the locker side, the non-contact IC tag 21, the key exchange function 22, and the personal identification number transmission / reception function 23 (email function etc.) are also incorporated in the cellular phone 20 on the unlocker side. .

  The key opening / closing device 30 includes a number input device 31 including numerical buttons and numerical keys for manually inputting a personal identification number as personal identification information input means, as in the case of a conventional key opening / closing device. A locking / unlocking device 34 for locking is provided. In addition to this, in this embodiment, the non-contact IC chip communication function 32 and the non-contact IC chip communication function 32 of the device side communication means for short-distance communication which is a transmission / reception unit of the personal identification number signal unique to the present invention are provided. A reception number signal conversion device 33 is provided for converting the password signal received in this way into information equivalent to the password information input from the number input device 31.

  In the locking / unlocking system of FIG. 1, the lock / unlock code number signal of the locking / unlocking device 34 in the key opening / closing device 30 is a non-contact IC tag signal and a mobile terminal such as the mobile phone 10, 20 and the key. The data is exchanged with the opening / closing device 30, and is converted into a personal identification number used for locking / unlocking the key of the locking / unlocking device 34 by the reception number signal conversion device 33 in the key opening / closing device 30. In addition, the personal identification number inputted to the mobile phone 10 on the locker side is obtained by using an electronic mail (E-Mail) function which is one of communication functions between mobile terminals such as the mobile phones 10 and 20. Is transmitted from the mobile phone 10 on the side to the mobile phone 20 on the unlocker side.

  Thus, in the present embodiment, the personal identification number originally input manually is used as a personal identification number signal for a non-contact IC tag signal via the non-contact IC tags 11 and 21 and the non-contact IC chip communication function 32. Therefore, even if the PIN is a number with a large number of digits or a PIN that is frequently changed, it can be accurately and quickly applied to the key to be locked and unlocked. The password can be entered. In addition, the locker's mobile phone 20 determined as a necessary partner by the locker using the communication function (e-mail function in this embodiment) of the personal identification number transmission / reception function 13 of the mobile phone 10 is applied to the locker. Can be notified of information related to the password set by.

(Description of operation of embodiment)
Next, with respect to the operation of the locking / unlocking system shown in FIG. 1, an example of the operation in the case of locking by inputting a personal identification number using the number input device 31 on the key opening / closing device 30 side is shown in the flowchart shown in FIG. Use and explain. FIG. 2 is a flowchart showing an example of the operation of the locking / unlocking system shown in FIG. 1 and shows an example in which the locking person and the unlocking person are different, but the locking person and the unlocking person are the same. However, the operation as the locking / unlocking system is the same.

  In the flowchart of FIG. 2, first, the locker A calls the key exchange function 12 of the mobile phone 10 of the locker A, sets the lock mode, and sets the unlocker B as the necessary unlocking target person. Set (step S001). The number of persons to be unlocked is not limited to one, and a plurality of persons can be set.

  Next, the locker A uses a number input device 31 installed in the key opening / closing device 30 to input an arbitrary number as a personal identification number for locking and unlocking the key of the locking / unlocking device 34 ( Step S002). For example, when applying a method in which the code number is changed every time locking is performed, the key opening / closing device 30 is not entered manually by the user, and the key opening / closing device 30 is instructed by the user. A value randomly generated by the password information generating means may be used as a password for locking and unlocking.

  A locker who has input a personal identification number or a person who wants to obtain a personal identification number randomly generated by the key opening / closing device 30 connects the non-contact IC tag 11 of the mobile phone 10 to the non-contact IC of the key opening / closing device 30. Hold it over the chip communication function 32. Thereby, locking by the password entered by the number input device 31 is performed by the locking / unlocking device 34, and the password is confirmed. At the same time, the password entered by the number input device 31 or the password randomly generated in the key switch 30 from the contactless IC chip communication function 32 of the key switch 30 to the contactless IC tag 11 of the mobile phone 10. Is transferred (step S003).

  The cellular phone 10 to which the password has been transferred reads the transferred password by the key exchange function 12, and the unlocked password B set in step S001 by the password transmission / reception function 13 is read. Is transmitted to the mobile phone 20 (step S004). The personal identification number transmission / reception function 13 for transmitting the personal identification number to the cellular phone 20 of the unlocking person B uses a function possessed by a normal portable terminal such as an electronic mail (E-Mail) function or a PUSH (push) message function. To do. Although the implementation of the personal identification number transmission / reception function 13 depends on the application, it is assumed here that the personal identification number transmission / reception function 13 is transmitted using an electronic mail (E-Mail) function that is transmitted and received via the mail server 40.

  The operation of locking the key of the locking / unlocking device 34 of the key opening / closing device 30 is thus completed. Next, the operation of unlocking the key of the locking / unlocking device 34 of the key opening / closing device 30 will be described.

  In the flowchart of FIG. 2, the cell phone 20 of the unlocking person B receives the code number transmitted from the cell phone 10 of the locker A by the code number transmission / reception function 23 using the electronic mail (E-Mail) function. (Step S005).

  The unlocker B calls the key exchange function 22 of the mobile phone 20 of the unlocker B, sets the unlock mode, and reads the received personal identification number. Further, the received password is re-edited as necessary (step S006).

  Next, the unlocker B holds the non-contact IC tag 21 of the mobile phone 20 over the non-contact IC chip communication function 32 of the key opening / closing device 30. Thereby, the personal identification number read into the key exchange function 22 of the cellular phone 20 is transferred to the key opening / closing device 30 as a personal identification number signal for non-contact IC tag communication (step S007).

  The key opening / closing device 30 converts the personal identification number signal transferred from the cellular phone 20 into information equivalent to the personal identification number when it is input from the number input device 31 using the reception number signal conversion device 33, and is locked. Input to the unlocking device 34 (step S008).

  If the password converted by the reception number signal converter 33 matches the password at the time of locking (in the case of “match” in step S010), the lock / unlock device 34 is unlocked. On the other hand, if the two numbers do not match (in the case of “mismatch” in step S010), the process returns to step S006, re-reads or re-edits the password, and repeats the processing from step S007.

  Alternatively, when the unlocking person B manually enters the unlocking code number from the number input device 31 as in the conventional method, the unlocking operation is performed by the number input device 31 instead of steps S006 to S008. A personal identification number is entered (step S009). Therefore, if the personal identification number is manually input and does not match the personal identification number at the time of locking, the procedure from step S009 is repeated.

  In the case where the unlocker B wants to change a part of the password from the locker A read into the key exchange function 22 of the mobile phone 20 as in the case where the password does not match the password at the time of locking. In step S006, the code number read into the key exchange function 22 is re-edited, and in step S007, the contactless IC tag 21 of the mobile phone 20 is connected to the contactless IC chip communication of the key opening / closing device 30 again. It can be held over the function 32. Alternatively, when the password read in the key exchange function 22 is re-edited in step S006, some digits of the password are deleted, and the password related to the deleted digit is manually numbered. It is also possible to input from the input device 31.

  In the present embodiment, the contactless IC tags 11 and 21 are used to communicate with the key opening / closing device 30 side. However, any alternative communication means for short-range communication may be used. Others such as Bluetooth, which is a general-purpose short-range communication method, IrDA (Infrared Data Association) for infrared communication, UWB (Ultra Wide Band) capable of high-speed communication, Zigbee capable of reducing power consumption and price, etc. The communication method may be used.

(Explanation of effect of embodiment)
As described in detail above, in the present embodiment, the following effects can be achieved.

  The first effect is not to authenticate with a unique number of a mobile terminal (for example, the mobile phone 10 or 20) as password information (for example, a password) for locking / unlocking a key, but to perform password information (for example, a password). Since the locker arbitrarily sets it and uses a mechanism for transferring it to another person (unlocker) who needs the unlocking operation as necessary, the key of the key opening / closing device 30 and the portable terminal It is not necessary to register (for example, the mobile phones 10 and 20) in advance. Therefore, any lock and unlock system that employs the present embodiment can be used universally without any pre-registration.

  The second effect is that the key opening / closing device 30 of the password information input method can be unlocked without directly inputting the password information (for example, the password number) to the password information input device (for example, the number input device 31). Entering the password information (for example, the password) previously transferred to the mobile terminal of the person B (for example, the mobile phone 20) using a short-range communication function (for example, a communication function for a non-contact IC tag) Therefore, at the time of unlocking, there is no longer any stickiness or error when inputting the password information (for example, the password) to the key opening / closing device 30. Therefore, the staying time in front of the key opening / closing device 30 can be shortened. That is, the key opening / closing device 30 can be unlocked quickly. In addition, since the arbitrarily set password information can be recorded on the locker's mobile terminal (for example, the mobile phone 10) each time the lock is performed, the locker himself / herself can be stored even if the password information is changed every time the lock is performed. However, the key opening / closing device 30 can be reliably unlocked by using a mobile terminal (for example, the locker's mobile phone 10 or the unlocker's mobile phone 20) at the time of unlocking. .

  As a third effect, as a method of notifying the unlocking person B other than the locker A himself / herself the password information (for example, the password) determined at the time of locking, a portable terminal ( For example, the personal identification information (for example, a personal identification number) can be notified using a communication function (for example, an electronic mail (E-Mail) function) provided in the cellular phones 10 and 20). Therefore, the unlocking person B to whom the personal identification information (for example, personal identification number) is notified can perform the unlocking as quickly as the locking person A. Furthermore, it is possible to have a feature that the unlocking person B can be limited every time the locking is performed.

(Other embodiments of the present invention)
Next, another embodiment of the present invention will be described. In other embodiments of the present invention, the basic configuration is the same as that of the above-described embodiment, but a method of inputting a personal identification number is different from that of the above-described embodiment. That is, in this embodiment, instead of using the number input device 31 on the key opening / closing device 30 side as a device for inputting a personal identification number which is an example of personal identification information for locking and unlocking a key, the mobile phone of the locker A is used. The case where 10 numeric keys are used is shown.

  FIG. 3 is a flowchart showing an example of the operation of the locking / unlocking system shown in FIG. 1 different from FIG. 2, and similarly to the case of FIG. 2, shows an example where the locker and the unlocker are different, Even if the locker and the unlocker are the same, the operation as the lock / unlock system is the same. Instead of inputting a new password, a password stored in advance in the cellular phone 10 of the locker A may be used.

  In the flowchart of FIG. 3, first, the locker A calls the key exchange function 12 of the mobile phone 10 of the locker A and sets it to the lock mode as in the case of FIG. Unlocker B is set as a person (step S101). The number of persons to be unlocked is not limited to one, and a plurality of persons can be set.

  Next, unlike the case of FIG. 2, the locker A uses the numeric keys of the locker A's mobile phone 10 instead of using the number input device 31 of the key opening / closing device 30 to enter the key exchange function 12. On the other hand, an arbitrary number is input as a security code for locking and unlocking the key of the locking and unlocking device 34 (step S102). Alternatively, a password stored in advance in the mobile phone 10 may be called and set in the key exchange function 12. In addition, for example, when applying a method in which the code number changes every time locking is performed, the number as the code number is not input from the numerical key, and the mobile phone is instructed by the user. You may make it use the random value produced | generated by the 10 PIN information generation means as a PIN code for locking and unlocking.

  The locker who has input the password or the locker who has acquired the password randomly generated by the mobile phone 10 connects the non-contact IC tag 11 of the mobile phone 10 to the key opening / closing device 30 as in the case of FIG. Over the non-contact IC chip communication function 32. As a result, the password set in the key exchange function 12 in step S102 is transferred from the contactless IC tag 11 of the mobile phone 10 to the contactless IC chip communication function 32 of the key opening / closing device 30 (step S103). . Thereby, locking by the code number set to the key exchange function 12 in step S102 is performed by the lock / unlock device 34, and the code number is determined.

  Further, the cellular phone 10 transmits the personal identification number set in the key exchange function 12 to the cellular phone 20 of the unlocker B set in step S101 by the personal identification number transmission / reception function 13 (step S104). The personal identification number transmission / reception function 13 for transmitting the personal identification number to the cellular phone 20 of the unlocking person B is the same as the case of FIG. 2, and an ordinary portable terminal such as an electronic mail (E-Mail) function or a PUSH (push) message function is used. Use the functions you have. Although the implementation of the personal identification number transmission / reception function 13 depends on the application, it is assumed here that the personal identification number transmission / reception function 13 is transmitted using an electronic mail (E-Mail) function that is transmitted and received via the mail server 40.

  The operation of locking the key of the locking / unlocking device 34 of the key opening / closing device 30 is thus completed. Next, the operation of unlocking the key of the locking / unlocking device 34 of the key opening / closing device 30 will be described.

  In the flowchart of FIG. 3, the mobile phone 20 of the unlocker B transmits from the mobile phone 10 of the locker A by the password transmission / reception function 23 using the E-Mail function, as in FIG. 2. The received password is received (step S105).

  As in the case of FIG. 2, the unlocker B calls the key exchange function 22 of the mobile phone 20 of the unlocker B, sets the unlock mode, and reads the received personal identification number. Further, the received personal identification number is re-edited as necessary (step S106).

  Next, the unlocker B holds the non-contact IC tag 21 of the mobile phone 20 over the non-contact IC chip communication function 32 of the key opening / closing device 30 as in the case of FIG. Thereby, the personal identification number read into the key exchange function 22 of the cellular phone 20 is transferred to the key opening / closing device 30 as a personal identification number signal for non-contact IC tag communication (step S107).

  Alternatively, when the unlocker B manually inputs the unlocking code from the number input device 31 as in the conventional method, the unlocking operation is performed by the number input device 31 instead of steps S106 to S108. A personal identification number is input (step S109). Therefore, if the personal identification number is manually input and does not match the personal identification number at the time of locking, the procedure after step S109 is repeated.

  In the case where the unlocker B wants to change a part of the password from the locker A read into the key exchange function 22 of the mobile phone 20 as in the case where the password does not match the password at the time of locking. In step S106, the password read into the key exchange function 22 is re-edited, and in step S107, the non-contact IC tag 21 of the mobile phone 20 is connected to the non-contact IC chip communication of the key opening / closing device 30 again. It can be held over the function 32. Alternatively, when the password read in the key exchange function 22 is re-edited in step S106, some digits of the password are deleted, and the password related to the deleted digit is manually numbered. It is also possible to input from the input device 31.

  As described above, in the operation example of this embodiment shown in FIG. 3, it is possible to perform not only unlocking but also locking using the personal identification number set on the side of the cellular phone 10 of the locker A. If it is a premise that the manual input operation is not performed as in Step 109 of 3, the effect that the number input device 31 as the password input means on the key opening / closing device 30 side can be deleted is obtained.

  Also in this embodiment, the non-contact IC tags 11 and 21 are used to communicate with the key opening / closing device 30 side. However, as in the case of FIG. For example, Bluetooth, which is a general-purpose short-range communication method, IrDA (Infrared Data Association) for infrared communication, UWB (Ultra Wide Band) capable of high-speed communication, low power consumption, and low price It is also possible to use other communication methods such as Zigbee.
