When the actuator 43 is deactivated, the plunger 43a is retracted, and the container 46a is sealed by the sealing plug 46b again by the repulsive force of the spring 46f. The actuator 43 outputs an open signal from the open / close sensor 44 in spite of the fact that the unlocking actuator 42 does not operate.
Only when inputting to 7, the control signal from the control circuit 37 operates.

A method of locking and unlocking the valuable transportation case constructed as above and an operation in the case of theft will be described. (a) At the time of unlocking the case First, carry in the room 50 a case 30 for transporting valuables, which is a bundle of bills and contains a large amount of cash. When the power of the external device 10 is on, the identification code inquiry signal is automatically transmitted from the first antenna 12 of the external device 10 to the second antenna 32 of the case 30. This interrogation signal is a binarized digital signal. This digital signal is emitted from a signal generator (not shown) in the first control circuit 17 and is modulated by the modulation circuit 14. The RF circuit 13 amplifies this modulated signal and transmits it from the first antenna 12. Examples of this modulation include ASK (amplitude modulation), FSK (frequency modulation) or PSK (phase modulation). Next, when the radio wave of the interrogation signal is received by the second antenna 32 of the case 30, only the signal necessary for demodulation is taken in by the RF circuit 33 of the case 30, and the demodulation circuit 35 reproduces the interrogation signal of the original digital signal to generate the second interrogation signal. Input to the control circuit 37. When the second control circuit 37 receives this inquiry signal, the memory 39
Transmits an identification code unique to the case to the external device 10. The transmission of this identification code is performed by modulating the binarized identification code by the modulation circuit 34 of the case, amplifying it by the RF circuit 33, and transmitting it from the second antenna 32.

Next, in the external device 10 which has received the identification code, the binarized authentication data for unlocking the case carried into the room 50 from the many cases is stored in the memory 1 thereof.
9 and sends this authentication data to case 30 in the same way as the interrogation signal. The second control circuit 37 of the case 30 which receives this authentication data stores the authentication data in the memory 39.
The password is compared with the password stored in advance, and only when the password is matched, the actuator 42 is operated for a predetermined time by a built-in timer (not shown). As a result, the latch 45a of the case 30 is disengaged from the striker 45b, the case 30 is unlocked, the lid 30b is opened, and cash consisting of a banknote bundle can be taken out. The operator can confirm the transmission / reception of data between the case and the external device during this period on the display 20. When the lid 30b is opened, an open signal is input from the opening / closing sensor 44 to the second control circuit 37, but the unlocking actuator 42 is operating, so the actuator 43 of the polluted liquid ejecting device 46 does not operate. Actuator 42
After a lapse of the operating time, the solenoid is demagnetized and the latch 45a is returned to the position shown by the solid line in FIG. 6 by the spring 45c. In the unlocking procedure, the external device 10 first transmits a case identification code inquiry signal, and the external device 10
Reads the authentication code based on the case-unique identification code transmitted from the case from the memory, and then transmits this authentication code to the case to unlock the case. A unique authentication code may be transmitted to the case to unlock it.

(B) When locking the case When the lid 30b is closed after the cash consisting of the banknote bundle is stored in the valuables transport case 30, the latch 45a is moved to the solid line position by the striker 45b due to the pressing force of the lid 30b. After moving from to the position of the broken line, it returns to the position of the solid line again and is locked by the striker 45b. Instead of operating the actuator 42 with a timer, the actuator 45 may be positively deactivated by moving a signal between an external device and the case to move the latch 45a to lock the case 30.

(C) When the cover of the case is forcibly opened, if the criminal who robs the case opens the cover 30b without relying on the unlocking operation of the above (a), first an opening signal is input from the opening / closing sensor 44 to the control circuit 37. To do. On the other hand, since the control circuit 37 does not operate the actuator 42, the control circuit 37 determines that the lid is opened due to theft and operates the actuator 43 of the polluted liquid ejecting device 46. As a result, the sealing plug 46d is disengaged, and the contaminated liquid is vigorously ejected from the ejection pipe 46c into the case,
If the case has a banknote bundle, it contaminates the banknote and renders it unusable.

In the above embodiment, when the authentication data is sent from the external device 10 to the case 30, the first control circuit 17 automatically reads the authentication data from the memory 19 and sends it to the case 30. Instead of reading the authentication data from the memory, the operator may input the authentication data from the input device 16 and send it to the case 30.
Yes.

As described above, according to the present invention, R
By using the FID technology, by transmitting and receiving the locking / unlocking data between the external device and the valuables transport case, a complicated code can be encrypted, and unlocking or locking / unlocking by anyone other than the related person. Can be made virtually impossible to ensure high security. Further, unlike magnetic cards and IC cards, it can be unlocked or locked without contact, so that regular maintenance is unnecessary. Since the case for transporting valuables does not have a keyhole, the criminal who robs the case does not force the guard to enter the key, and damage to the guard due to the robbery is reduced. Further, when the criminal who stole the case forcibly opens the case, the polluted liquid stains the valuables and disables the use of the valuables.
