  By the way, there is known a lock that allows a user to lock and unlock a protection box without contact, as in Patent Literature 1. However, in Patent Literature 1, a data communication unit and an electric lock must be provided in each protection box. The cost of the protective box increases. In particular, the electric lock includes a first solenoid, a second solenoid, a link, a spring, and the like, has a large number of parts, and has a large number of movable parts, which may further increase the cost. In a fully automatic safe deposit box system, about tens to hundreds of protective boxes may be installed in one system, and if the unit price of the protective box increases, the cost increase of the entire automatic safe deposit box system increases. Would. Therefore, there is a strong demand to reduce the unit price of the protective box.

  The present invention has been made in view of the above points, and an object of the present invention is to reduce the cost of a protective box without lowering the security of the protective box, and to reduce the cost of introducing a fully automatic safe deposit box system. Is to reduce it.

  In order to achieve the above object, in the present invention, a magnetic lock unit using a plurality of reciprocally movable magnets is provided in a protective box, and a magnetic key unit for unlocking the magnetic lock unit by the magnetic force of an electromagnet is provided on the booth equipment side. , A plurality of magnetic lock units can be unlocked by one magnetic key unit.

  According to a first aspect of the present invention, there is provided a safety box locking / unlocking device for locking / unlocking a safety box of a fully automatic safety box system, comprising: a magnetic lock unit provided in the safety box; A magnetic key unit that is provided in a booth device of the safety box system and unlocks the magnetic lock unit of the safety box for a safety box that is housed in a protection box use opening of the booth device; Comprises a plurality of magnets, a magnet support plate for supporting the magnets in a reciprocating manner, and a lock plate having a lock hole into which the magnets are inserted and engaged, wherein the magnetic key unit is the magnetic lock unit. A plurality of electromagnets arranged so as to respectively correspond to the plurality of magnets, and when it is determined that the safe box for protection is for a user in the booth, the magnet is removed from the lock hole. Missing Characterized in that it is configured to perform unlocking control for supplying current to the electromagnet such that the non-locking position.

  According to this configuration, while the safe box is kept in the safe room, the cover of the safe box cannot be opened, and the magnet of the magnetic lock unit is inserted into the lock hole of the lock plate. When the magnet is inserted into the lock hole, the lock plate is fixed to the magnet support plate, so that relative movement becomes impossible. This prevents the lid from being opened by anyone other than the user.

And stored in the storage device. The storage device may be provided in the booth device 103 or may be provided in an external control device. The storage device also stores the user's date of birth, biological information (for example, palm vein, finger vein, fingerprint, etc.), a password, and the like in association with each other.

  The user first inputs his / her date of birth outside the booth 102, and then performs biometric authentication using a biometric authentication device (not shown) installed outside the booth 102. If the authentication is successful, the door of the booth 102 opens, so that the user can enter the booth 102. Thereafter, the user operates the touch panel monitor 112 shown in FIG. 2 to select his or her safe deposit box number, and then inputs his / her personal identification number. If the password is correct, the booth transport device 110 transports the protection box 1 to the inside of the protection box use port 106. Then, when the “remove” button on the touch panel monitor 112 is operated, the opening / closing door 108 is opened.

  Next, the user performs biometric authentication using the biometric authentication device 113 in the booth 102. If the biometric authentication is successful, it is determined that the protection box 1 housed in the protection box use port 106 is for the user in the booth 102, while if the biometric authentication fails, the protection box use port 106 It is determined that the housed protection box 1 is not for the user in the booth 102. If the biometric authentication fails, the unlock pattern signal is not output to the magnetic key controller 305. On the other hand, if the biometric authentication succeeds, a signal related to the determination result is output to the magnetic key controller 305 as the unlock pattern signal.

  The magnetic key controller 305 supplies a current to the first to fourth electromagnets 301 to 304 so that the magnetic lock unit 4 is unlocked according to the unlock pattern signal.

  In addition, as a reception method of opening the door of the booth 102 and allowing the user to enter the booth 102, a pattern using only a biometric authentication, a pattern using only a biometric authentication, May have an authentication card for performing personal authentication, and a pattern using the authentication card may be used.
