Then, when the inserted optical key 36 can image an identical doll on the image capturing module 34, and the user also types 1 on the panel 50 in sequence and presses until the red LED is bright, 2 and presses to the red The LED is bright, 3 and pressurized until the blue LED is bright, and 4 and pressurized until the red LED is bright. In this way, the effect of unlocking the lock 26 unit can be achieved.

It is particularly important to note here that whether you insert the correct optical key first and then enter the correct pressure and password set, or enter the correct pressure and password set and then insert the correct optical key, the lock 26 can be unlocked. effect. On the contrary, as long as the optical lock, pressure, and password are not correct, the lock 26 cannot be opened.

The advantages of the present invention are:

1. The key to unlocking is the optical characteristics of the first and second optical elements on the optical key, and the optical characteristics cannot be read and copied by the naked eye or optical instruments. Therefore, even if the optical key is obtained by a third person, he/she cannot copy it at all.

Figure 5 shows the image captured by the image capture module after passing through the key unit; Figure 6 shows the image captured by the image capture module after rotating the second optical element at an angle image. With this feature, the manufacturer only needs to manufacture the same optical element and then set it on the carrier at different angles to produce different optical keys. This can greatly reduce manufacturing costs.

3. Reversing the first optical element and the second optical element, either only one optical element, or three or more optical elements can produce different imaging results.

4. If the optical key is lost, you only need to delete the corresponding control image in the storage unit to avoid the third person from obtaining the optical key and opening the optical lock.

5. Combined with the pressure of the password, it can produce a combination of many times more than the ordinary password lock, which greatly improves the security.

6. In the embodiment, only two applications for identifying pressure are proposed, but those with ordinary knowledge in the technical field can easily expand it to raise three, four, or more applications for identifying pressure.
