Either the flat IC tag (this embodiment) 27 or the transponder 25 is inserted into the recess 29, while the transponder (this embodiment) 25 or the IC tag that does not fit into the recess 29 is formed. These are supported in a sandwiched state by a pair of left and right support pieces 26, 26 fixedly projecting in the predetermined space 28. Desirably, the facing surface of the transponder (this embodiment) 25 formed in a horizontally long shape on the outer surface of the IC tag (this embodiment) 27 fitted in the recess 29 of the lid 3 via the adhesive layer 30 is provided. Adhere (see FIGS. 7 and 10). Desirably, when both 2 and 3 are coupled, the transponder 25 and the IC tag 27 are supported by the pressing protrusion 16 formed on the inner wall surface of the cover body 2.

(5) Transponder FIG. 12 is a schematic explanatory diagram of a transponder. The transponder 25 is disposed in a predetermined space 28 on the lid 3 side so as to overlap the IC tag 27 via a pair of left and right support pieces 26 and 26. The transponder 25 includes an antenna coil 32 and an IC chip 33 that is electrically connected to the antenna coil and stores first unique information (for example, key identification information). The antenna coil 32 is formed in a thin donut shape by winding a plurality of coated conductors, while the IC chip 33 is accommodated in the center of the antenna coil.

  Thus, the IC chip 33 as an information processing unit includes a CPU (control unit) 33a, a CPU memory 33b, a power supply circuit 33c, an antenna (antenna coil) 32, and other necessary circuits (radio frequency, modulation, demodulation, etc. Circuit) 33d, a capacitor (not shown), and the like.

  The power supply circuit 33 c includes a capacitor, and this capacitor forms a resonance circuit together with the antenna coil 32. When the antenna coil 32 receives a radio wave (frequency at which the resonance circuit resonates) R1 having a specific frequency, the capacitor is charged with electric power generated by the mutual induction action. The power supply circuit 33c rectifies and stabilizes this power and supplies it to the CPU 33a to activate the IC chip 33. Under the control of the CPU 33a, the memory 33b receives, for example, a read command by data communication of the radio wave R1 (for example, frequency 134.2 kHz) from the identification means 35 provided on the cylinder lock of the door as a fitting or the steering column of the vehicle 34. The stored data is read out accordingly, and the data is written in response to the write command from the identification means 35.

(6) IC tag 27
FIG. 13 is a schematic explanatory diagram of the IC tag 27. As described above, the IC tag 27 is fitted into the recess 29 in the predetermined space 28 on the lid 3 side. In addition, in this embodiment, it is supported by the transponder 25 supported by the support piece 26. The configuration of the IC tag 27 is the same as that of the transponder 25. That is, the IC chip 43 having the antenna coil 42, the CPU 43a, the memory 43b, the power supply circuit 43c, and the necessary circuit 43d stores second unique information (for example, information related to key movement).

Thus, the IC tag 27 is different from the transponder 25 in that an IC tag reader (information writing management device) 45 provided with a radio wave R2 (for example, frequency 13.56 MHz) different from that of the transponder inside or outside the building 44 is provided. It is a point to transmit to.
Therefore, the data structure stored in the memory 43b of the IC tag 27 is naturally different from that stored in the memory 33b of the transponder 25. Also, other necessary circuits (circuits relating to radio frequency, modulation, demodulation, etc.) 43d are naturally access circuits for the IC tag 27, and the access circuit 43d resonates with the radio wave R2, but is a transponder. It does not resonate with the radio wave R1 on the 25th side.

  By the way, the data structure in the memory 43b of the IC tag 27 is divided into, for example, areas a to d, the area a is security key information for authentication, the area b is unusable information related to the use of data, Area c stores information related to key movement (person-in / out information), and area d stores personal information related to the key owner. Note that the flowchart regarding the operations of the transponder 25 and the IC tag 27 is not a specific requirement of the present invention, and will be omitted.

  In the first example shown in the embodiment of the invention, the support piece 26 is formed in, for example, a U-shape that elastically displaces outward against the elastic force of the material itself. Although the both ends are supported, the shape of the support piece 26 can be arbitrarily changed.

  Next, FIG. 14 is an explanatory diagram of the second embodiment of the present invention. FIG. 14A is an explanatory view of the inside of the main body, similar to FIG. On the other hand, (b) of FIG. 14 is explanatory drawing inside a cover body like (a) of FIG. As is clear from the comparison between the two figures, in the second embodiment, the IC tag 27 and the transponder 25 are arranged in a predetermined space in the recess 2a inside the main body 2A so as to overlap each other, while the lid body. A protrusion 18 for pressing the transponder 25 and the IC tag 27 is formed in a predetermined space 28 of the recess 3a of 3A.

  That is, in the second embodiment, contrary to the first embodiment, a cover body 2A having a recess 2a in which a notch 7 for projecting a key is formed on the lower end side of the projecting wall-shaped peripheral wall 9, and a key head A key comprising a cover lid 3A that is joined to the cover body 2A so that a mechanical key K, which is removably fitted from the center of the cover body to the key projection notch 7, is not detached from the cover body 2A. In the head cover, a transponder 25 and an IC for transmitting a radio wave different from the transponder to an IC tag reader in a predetermined space 28A between the upper side of the key head a and the inner surface on the upper end portion side of the protruding wall-shaped peripheral wall 9. It is characterized in that the tag 27 is disposed so as to overlap.

Also in this second embodiment, a recess 29 is formed in a part of the bottom surface of the inner wall forming the predetermined space 28A of the cover body 2, and either the flat IC tag 27 or the transponder 25 is formed in this recess. On the other hand, either a transponder or an IC tag that does not fit in the recess is supported by a support piece 26 provided in the predetermined space 28A.
In addition, although not particularly shown, a protrusion for pressing the key head is appropriately formed on the inner wall surface of the cover lid.
