In an electronic lock device or an electronic lock system, a wireless signal transmitted by a wireless unit can be reliably received by an electronic lock body.

[0004]

The first invention of the present invention for solving the above-mentioned problems is an electronic lock body as described in claim 1, and is as follows. Based on the information received from the wireless transmission device, a lock that performs either one or both of an opening operation and a closing operation, a lock control unit, a shackle, a wireless reception circuit, and at least one of the shackles. The electronic lock body includes a portion, that is, the shackle also has an antenna that also functions as an antenna, and an electric wire that electrically connects the wireless reception circuit and the antenna.

A second invention of the present invention for solving the above problems is an electronic lock main body as described in claim 2, and is as follows. The electronic shackle according to claim 1, wherein the shackle shifts from a closed state to an open state by a control operation of the lock of the control means.

A third invention of the present invention for solving the above problems is an electronic lock main body as described in claim 3, and is as follows. The electronic lock main body comprises a storage case, and the storage case shifts from a closed state to an open state by a control operation of the lock of the control means. It is the electronic lock body.

A fourth invention of the present invention for solving the above-mentioned problems is an electronic lock main body as described in claim 4, and is as follows. The wireless transmission device is a wireless communication device having a reception function, and the wireless reception circuit is a wireless communication circuit having a transmission function. It is the electronic lock body.

[0008]

FIG. 1 is a block diagram of an electronic lock body according to the present invention. The wireless unit 1 is a wireless transmission device or a wireless communication device having a wireless transmission / reception function. The wireless unit 1 includes a CPU 3, a ROM 2 and a RAM 1.
It is an ordinary wireless device having 0 or the like, and transmits an unlock code or a lock code, or an unlock code and a lock code to the electronic lock body. Information to be transmitted to the electronic lock body 5 such as an unlock code is stored in the ROM 2. RA
M10 is a so-called work area, which is the electronic lock body 5
It is possible to temporarily store the data received from.
The electronic lock body 5 includes a shackle, that is, a clasp or clasp. This shackle 6
Also serves as an antenna for wireless reception. That is, the shackle and antenna 6 is metallic and has a portion exposed to the outside of the electronic lock body 5, and is connected to the wireless reception circuit 8 by the electric wire 11. The electronic lock body 5 that has received the unlock code (not shown) transmitted by the wireless unit 1 by the shackle and antenna 6 receives the unlock code by the control means 7 via the wireless receiving circuit 8 and locks the lock 9. Move from the closed state to the open state. Therefore, as shown by the alternate long and short dash line, the shackle and antenna 6 can be pulled up from the electronic lock body 5,
The shackle 6 is opened. When closing the opened shackle 6, the user may push the shackle (also the antenna) 6 by hand. A close command may be issued from the wireless unit 1 to the electronic lock body 5.

FIG. 2 is a block diagram showing an embodiment of the electronic lock body according to the present invention. The configuration of the wireless unit 1 is exactly the same as that of FIG. The number of shackles (6, 6a) provided in the electronic lock body may be two instead of one. Further, the shackle 6 that also serves as an antenna may be one or two or more. In FIG. 2, the shackle / antenna 6 also functions as an antenna, and the shackle 6a is a pure shackle that does not function as an antenna. Further, the electronic lock body 5 may be provided with a storage case 12 with a lock. In this storage case 12, for example, a key of a front door (such as an apartment or a house for sale) is stored. The storage case 12 is provided with a lock for the storage case, that is, a storage case lock 9a, and can be changed from the closed state to the open state by a command from the control means 7. To the control means 7 of the electronic lock body 5, as described above,
Since a command (unlocking code) can be sent from the wireless unit 1 via the shackle / antenna 6, the electric wire 11, and the wireless receiving circuit 8, the wireless unit 1 can unlock the storage case lock 9a. .

FIG. 3 is a schematic view showing another embodiment of the electronic lock body according to the present invention. A lock 9 for unlocking or locking the shackle / antenna 6 and the storage case 12.
May be one. That is, the electronic lock body may be configured such that when the lock 9 is unlocked, the shackle / antenna 6 and the storage case 12 simultaneously shift from the closed state to the open state. Further, the wireless receiving circuit of the electronic lock body 5 may be a wireless communication circuit 8a having a transmitting / receiving function.

[0011]

Since the electronic lock body according to the present invention according to the present invention has the structure as described above, it has the following effects. The electronic lock body has a shackle exposed to the outside of the housing of the electronic lock body, and the shackle also functions as an antenna. Therefore, in the electronic lock device or the electronic lock system, the wireless signal transmitted by the wireless unit is transmitted to the electronic lock. The body can now reliably receive.
