Security Card Recognition System

Abstract

Thefts, accidents, and other problems caused by unauthorized lock picking and other methods continue to occur. [Solution] The system comprises a locking device that opens and closes with a key, and a recognition box that is linked to the locking device and recognizes an original card 2 that has a unique shape that can be distinguished from others. This recognition box has a recognition means that recognizes the unique shape of the original card 2 that can be distinguished from others from at least one direction from the entrance side when the original card 2 is inserted, and is linked so that the key can only be used when the inserted original card 2 is recognized as the original card 2 that corresponds to the recognition box. Furthermore, the original card 2 cannot be removed once the original card 2 that corresponds to the recognition box is inserted and unlocked, and can be removed once the locking device is locked and the key is removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An example of an embodiment of the present invention will be described with reference to Figures 1 to 11. An original card 2 as shown in Figure 2 is inserted into the recognition box shown in Figure 1.

[0013] After the original card 2 is inserted, it is fixed in the state shown in Figure 3. The state in Figure 3(a) is a recognition-suitable state, but the state in Figure 3(b) is a recognition-unsuitable state because it has not been fixed.

[0014] 4, the original card 2 is inserted in the recognition boxes 1a and 1b surrounded by the pin case 4. In this example, the original card 2 is recognized from four directions by a plurality of pins 5a.

[0015] Figure 5 shows the internal structure of the pin case 4. When an original card 2 corresponding to a recognition box is inserted into a recognition box 1a or 1b, the pin 5a, which is pressed downward in the figure by the pin spring 5b within the cylinder 3, moves, and a shear line 5c is established.

[0016] In this embodiment, the pin 5a is designed as shown in FIG.

[0017] FIG. 7 shows a perspective view of a shear line shutter 6a and a shear line shutter plate 6b that slide into the shear line 5c.

[0018] Fig. 8 shows a cross-sectional view of the recognition box lid 1b and its vicinity when the original card 2 is inserted. After sliding the recognition box lid 1b, the pin case 4 is pushed in from above to recognize the original card 2 corresponding to the recognition boxes 1a, 1b. An outline of the pin case 4 is shown in Fig. 9.

[0019] If the card is an original card 2 that corresponds to the recognition boxes 1a and 1b, the shear line 5c will appear as a square as shown in Figure 4. This means that the card has been recognized as an original card 2 that completely corresponds to the recognition boxes 1a and 1b from all four directions.

[0020] The shear line shutter 6a shown in FIG. 7 is slid into the square shear line 5c.

[0021] When the shear line shutter 6a slides in, the shear line shutter plate 6b also slides. The sliding of this shutter plate 6b is linked to the cylinder mouth closing plate 7 by a gear or a shaft, and if the original card 2 is inserted, the keyhole of the cylinder is opened.

[0022] Furthermore, the flow chart shown in Fig. 11 will be used to explain the linkage between the security card recognition system and a locking device that opens and closes using a key. The original card 2 can only be recognized by the corresponding recognition box 1a, 1b. The original card 2 is inserted (S3), the cylinder opening closing plate 7 is opened (S5), and when the lock can be opened (S6), the original card insertion port 1c is locked by the lid 1b (S7). The shape of the original card 2 is recognized by closing the insertion port 1b of the recognition box, which prevents picking. Next, when the lock is locked (S▲3▼), the lock by the cover 1b of the original card insertion port 1c is released (S▲4▼), the key is removed (S▲5▼), the cylinder keyhole is closed with the cylinder port closing plate 7 S▲8▼, and the original card 2 is removed (S▲7▼). Since the keyhole is closed and the original card 2 has been removed, lock picking is prevented. Therefore, by locking the original card insertion port 1c with the cover 1b in conjunction with the key of the locking device, the original card 2 can be prevented from being stolen and the key can only be used when the original card 2 is inserted.

[0023] Furthermore, when locking the door from inside the room, an inner lock on the cover 1b of the original card insertion port 1c from the inside is necessary to prevent theft of the card. This is because there is a possibility of theft occurring when someone picks the cylinder from the outside, locks the door, removes the original card 2, and makes a copy. Furthermore, when going out with the door locked, a simple lock can be applied to the cover 1b of the original card insertion port 1c to prevent tampering.

[0024] Fig. 10 shows the linkage with the deadbolt. When the door is locked from the outside, both deadbolts 9 and 10 close due to linkage with the cylinder cam 8, and the original card insertion slot linked with the deadbolt 9 opens. When the door is locked from the inside, only the deadbolt 10 closes, and the original card insertion slot 1c does not open.
