Description

[Detailed Description of the Invention] (Technical Field) The present invention provides a method for unlocking a vault door using a magnetic card or the like.
This relates to a one-click device.

(Prior art) Conventionally, the lock device (lock) of the door of the safe of a public telephone is
It was configured to be unlocked using a key made from a metal plate, etc. However, attaching a white lock with a different key would increase the cost, and the task of recovering the C safe would be complicated due to the huge number of keys. Therefore, a plurality of, for example, one of three types of locks are attached to a large number of telephones, and each of these locks is unlocked using a common key. For this reason, there is a problem in that if even one key is lost, the locks of many telephones must be replaced.

(Object of the Invention) In view of the above-mentioned problems, the present invention provides a magnetic card or an IC card as a key.
To provide a locking device using a readable recording card such as a card (herein simply referred to as a card), which can be unlocked with another card even if the card is lost, but cannot be unlocked with the lost card. The purpose is to

(Structure of the Invention) In order to achieve the above object, the present invention includes a plurality of cards whose numbers are recorded in advance in the order of use, a card unit for reading the recorded contents of the cards, and a plurality of preset usable cards. The card unit includes a memory for storing the card number and the used card number, a cock mechanism for the vault door that can be unlocked by an electric signal, and a control section for controlling these. The one-cock mechanism is unlocked when the number of the read card is one of the preset plurality of usable card numbers and is the same as or later than the number of the card used immediately before. It is characterized by the fact that it was done as follows.

(Embodiment) FIG. 1 shows an embodiment of the present invention, in which an example is shown in which the present invention is applied to a known magnetic card type public telephone.

In the figure, 1 is a public telephone, 2 is a card, 3 is a card unit that reads the recorded contents of the card, 4 is a coin mechanism that stores or returns coins, 5 is an exchangeable safe, and 6 is detailed later. 7 is a control unit, 8 is a memory, 9 is a station interface unit, 10 is a communication circuit, 11 is a battery, and 12 is a power supply circuit. Card 2 has the same configuration as a normal magnetic card for bill payment,
Information indicating that the card is for safe collection, etc. Number N (=1.2゜...) set in the order of use of the card
Information indicating the information is written. Further, two or more types of usable card numbers are set in advance in the memory 8, and the number of the used card is also stored.

FIG. 4 is a sectional view of the main part of the lock Ia#/i6, and FIG. 5 is a sectional view taken along the line v--v. In the figure, 13 is a public telephone, 14 is a vault door, and 1
5 is a lock plate, 16 is a lock plate driving solenoid, 17 is a door opening/closing detection rod, and 18 is a door opening/closing detection switch. In this locking mechanism 6, if the inserted safe collection card 2 is appropriate, a solenoid 16 is operated by an electric signal under the control of the control unit 7, and the locking plate 15 is pushed upward.
The lock plate 15 is [! It is designed to come off from the temporary support 19. The vault door 14 is connected to the spring 20 of the door opening/closing detection rod 11.
Since it is constantly being pushed in the opening direction by the hinge 21, it opens slightly around the hinge 21. After replacing the safe 5 with a new one, when the collector closes the vault door 14 by hand, the door opening/closing detection rod 17 is activated by the detection rod receiver 22 to activate the door opening/closing detection switch 18.
Based on this information, the controller 7 immediately restores the solenoid 16 and returns the card.

As a result, the lock plate 15 is inserted into the lock plate receiver 19, and the vault door 14 is locked.

In addition, functions such as storing the card type and identification order, unlocking, etc. are powered by the battery 11 charged by the power supply circuit 12 even if the commercial power supply fails, so the functions will not be stopped or the memory will not be cleared.

Next, we will explain the operation, but here we will use three types of cards A, B, and C as card 2 (N = 1, N = 2, respectively).
．． N-3) is set in the memory 8 to be used.For normal calls, a charge payment card is inserted into the card unit 3, but when a coin is inserted into the coin mechanism 4, the control unit 7 makes a call to a station (not shown) using the station interface section 9. If you dial, you can talk to the other party using the communication circuit 1°.The person who replaces the safe 5 with a new empty safe calls the number N=1. Card A to Carbini 1 nits 1
-3, the control unit 7 of the public telephone 1 compares the written identification information of the card 2 with the information stored in the memory 8 as shown in FIG. >, the locking mechanism 6 of the safe door is unlocked and the safe can be replaced.A.

If the card is a legitimate card other than B or C, 1] Allows dialing without unlocking the footer structure. If it is not a genuine card, the card will be returned and you will not be able to unlock or use the card.

For example, if Card A is lost, a collector immediately changes all public telephone safe collection cards in the area to Card B. That is, when card B is inserted into public telephone 1, control unit 7 sets number N to 2 and stores it in memory 8 as N=2.
Memorize this and unlock it.

Thereafter, even if card A (N=1) is inserted, the lock will not be unlocked because N is stored as 2.

If you lose card B, change it to card C,
When inserted into the public telephone 1, N=3 will be stored and the phone will be unlocked. After that, even if Card A and Card B are inserted, they will be returned immediately and will not be unlocked.

The above explanation has been made using three types of cards, A, B, and C, but the same effect can be obtained by using two or four or more types of cards. In addition, after using the A, B, and 03 types of cards up to the C card, you can continue to use the card by replacing it with the memory 8 that stores the write information of the three types of cards, C, D, and E at an appropriate time. Then, card E becomes available for use.

In this embodiment, the write identification information and number corresponding to the card type are stored in the memory 8 backed up by the battery 11, but it is also possible to replace them with a DIP switch or the like.
It is Noh.

In addition, when card A is lost, the collector does not wait until the next time the safe is recovered, but immediately visits public telephones 1 and collects card B.
By inserting the card A, it is possible to prevent the safe from being stolen by the card A.

In addition, as shown in Figure 3, if the vault door does not open just by inserting the card, the vault door can be opened by entering, for example, a 3-digit PIN from the dial of the public telephone Ia1 and pressing it correctly. It can also be set as In this case, the password can be constant regardless of the card type, or can be different depending on the card type. Further, this password can be stored in the memory 8 in the public telephone ta1, or can be recorded on the card as written information. By using a personal identification number, the mere loss of a card does not immediately lead to the safe being stolen, and it becomes possible to take measures such as replacing the card with another type of card at an appropriate time depending on the situation.

Note that although a magnetic card is used in this embodiment, an IC card or other cards can also be used.

Also, so far I have explained using public telephones as an example,
It can also be used in vending machines, etc.

(Effects of the Invention) As explained above, according to the present invention, a plurality of IC cards whose numbers are recorded in advance in the order of use, an I-nit card that reads the recorded contents of the cards, and a plurality of IC cards whose numbers are recorded in advance in the order of use; It is equipped with a memory that stores the number of possible cards and the number of the used card, a locking mechanism for the door of the vault that can be unlocked by an electric signal, and a control unit that controls these, which can be read by the cartconit. When the number of the card used is one of the plurality of usable card numbers set in advance and is the same as or later than the number of the card used immediately before, the [1] key is unlocked. As a result, even if the card used as a key is lost, it can be unlocked using the card with the next number recorded on it, and by using the next card, unlocking by the lost card can be prevented. Even when used in common with public telephones, etc., there is an advantage that there is no need to replace the device.
