FIG. 3C is a perspective view of the key after assembling the ID pin according to the embodiment of the present invention, and FIG. 4C is a perspective view of the ID pin according to the embodiment of the present invention. 1 is a schematic view of a slider according to an embodiment of the present invention. The door locking / unlocking device 2 includes an ID verification unit 20 that verifies the ID of the key and the ID of the vehicle 1, and door locking / unlocking that controls locking and unlocking of the door 11 based on the ID verification result of the ID verification unit 20. It is comprised roughly with the mechanism part 25. FIG.

(Configuration of ID verification unit 20)
The ID collation unit 20 is roughly configured by a rectangular key 200, a sleeve 210, a slider 230, a lock pin 240, and a pin 241. The slider 230 is fixed to the sleeve 210 by the lock pin 240. . Each of these will be described in detail below.

(Configuration of key 200)
The key 200 includes a key body 201 having a rectangular shape, a handle 201a that is provided on the outer surface of the key body 201 in the insertion direction of the key 200, and is a portion of the operator, a recess 202 provided in the key body 201, And a plurality of fixing pin holes 204 into which the fixing pins 205 are inserted are provided on the side surfaces of the key body 201.

  The ID pin 206 is a front end surface of the ID pin 206, a front end of a pin 241 described later, a front end 206 a that is in contact with the key 200 when inserted into the key insertion slot 211, and a fixed pin hole 204 provided on the side surface of the key 200. In this embodiment, a set of four ID pins 206 is inserted into the recess 202, and the fixing pin 205 is inserted into the fixing pin hole 204 of the key 200 and the ID pin 206. The ID pin 206 is easily fixed to the key body 201 by being inserted into the fixed pin hole 207, and a predetermined ID is generated.

The ID pin 206 has a rectangular shape with a width W of 2 mm, for example, and its length L is determined according to the number of necessary IDs. For example, generally, the number of IDs for one vehicle type is desirably 1000 or more. In this embodiment, the number of ID pins 206, since 16 is, when the length is referred to as being as x, ID can be considered to be types x ^16. Now, assuming that there are two lengths L of the ID pin 206, there are 65536 IDs, and a practically sufficient number of IDs can be secured. Further, for example, reduce the number of ID pins 206 into four, when a length L is x as the number of ID becomes the ⁴ kinds ^x, when the length L was prepared ways 10, the number of ID is 10000 As a result, a sufficient number of IDs can be secured.

  Furthermore, since the ID pins 206 having different lengths L are very easy to assemble, and assembling is also easy, cutting or pressing a peak or a valley on the key like a conventional key cylinder lock. The manufacturing cost can be greatly reduced as compared with the method of manufacturing by the above. The combination of the ID pins 206 obtained by rotating the key 200 90 ° or 180 ° left and right is the same combination, but since the convex portion 203 is provided on the key body 201, the same combination It will not be.

  In addition, since the conventional key cylinder lock needs to rotate the key cylinder after the ID is verified, the key material has to be made of iron or a material with high hardness according to it, The door locking / unlocking device 2 according to the present embodiment simply inserts the key 200 into the key insertion slot 211 and operates the door handle, so that the material has a degree of freedom and can be made smaller.
