FIG. 5 is a functional block diagram showing a security device in an electronic lock device according to the present invention. FIG. 6 is a flowchart showing an example of the operation of the security device in the electronic lock device. All of these operations are performed within the control device 6.

With reference to FIGS. 5 and 6, the operation of the electronic lock device 2 will be explained first, and then the operation of the security device 3 will be explained.

The operation of the electronic lock device 2 will be explained below.

When the switch 5 is operated, the output signal from the switch 5 is sent to a gate section 63, a fixed number storage section 64, a fixed number comparison section 65, an arbitrary number storage control section 66, an arbitrary number comparison control section 68, and an arbitrary number comparison section. 69. Since switch 5 has been operated, the process moves to steps 5601, 5602, and 5603. If the output signal is a fixed number, the fixed number stored in advance is output from the fixed number storage section 64 and compared with the number input from the switch 5 in the fixed number comparison section 65. Here, it is assumed that a number for activating "1 tablet related" is input from switch 5 as a fixed number. Then, the output signal from the fixed number comparison section 65 enables the arbitrary number storage control section 66 and the arbitrary number comparison control section 68, and the process proceeds to step 5.
Moving on to 604. When the code is not stored in the arbitrary number storage unit 67, the arbitrary number storage control unit 66 is activated, and the code is set in the arbitrary number storage unit 67 by operating the switch 5 (that is, from step 5604 to step 8606 is executed.

Next, when switch 5 is operated, steps 5601 to 5
The process moves to step 604, and since it is determined that the code has been set by the arbitrary number storage fiIIJ control section 66, the process moves to step 5607. Then, the arbitrary number comparison control section 6
8 is activated, and the comparison section 69 compares the stored contents from the conversion number storage section 67 to determine whether the output signal output from this is "unlocked" by the operation VC of the switch 5. As a result of the comparison in the comparing section 69, if it is determined that the door is "locked", the process moves to steps 8607 to 5609, and the door lock actuator 7 is operated to lock the door. If it is determined that it is other than this, steps 8608 to 560
There are a lot of things to move to 1.

Here, the case of "unlocking" will be explained next.

Operate switch 5 and enter the code, Stella 7"
Steps 5601 to 5604 are followed by step 5607. The output signal from the switch 5 is supplied to an arbitrary number control section 68 and a comparison section 69.

The control unit 68 transfers the code from the storage unit B7- to the comparison unit f.
Supply it to the L key. In this comparing section q9, when the code inputted from the switch 5 and the code supplied from the storage section 67 match, the door lock actuator 7 is activated to unlock the door (step 5610). Next, if the security device 3 is set to the operating state, it is reset (step 5611).

The above is the operation of the electronic lock device 2.

Next, the operation of the security device 3 will be explained and explained below.

First, the switch 5 is operated to enable the security device 3 to operate. By inputting the fixed number through the switch 5, the goo 1 part 63 for the security device 3 is activated. This is nothing but a transition to steps 5601-5603%5612. Next, two or more predetermined switches among the switches 5 are operated (step 5612). If this is a set of 30 security devices, step 5
613 and 5614, the security device 3 is set. This is because the output signal of the switch 5 is supplied from the gate section 63 to the setting control means 62, and the control means 62 is activated.
This means that the alarm command forming means 61 is set to the operating state. This will set up the security device 3, so
Thereafter, steps 8601, 8615 and 5616 will be performed.

Here, when the door 4 is opened and the door switch 8 is closed, the process moves to step 5617.

A signal 100, which is often generated when the door switch 8 is closed, is applied to the alarm command forming means 61.

Then, the alarm command forming means 61 forms an alarm command 200 and supplies it to the alarm generating means IO. The alarm generating means 10 receives the alarm command 200 and generates an alarm sound. Such an operation is nothing but activation of the security device 3 in step -8617K.

In this embodiment, since the security device 3 is reset when the door is unlocked, it is necessary to set the security device 3 each time.

FIG. 7 is a flowchart showing another example of the operation of the security device of the electronic lock device according to the present invention. In FIG. 7, parts with the same functions as those in FIG. 6 are given the same reference numerals and their explanations will be omitted.

The difference between the operation example in FIG. 7 and the one in FIG. 6 is that when it is determined in step S613 that the security device 3 is not set, the reset of the security device 3 (step 8701) is determined. A flow for resetting the device 3 (step 5702), a flow for stopping the security device 3 provided in place of step 5611 in FIG. 6 (step 5703), and step 8616
If the security device 3 is not stopped in step 5703 when it is determined that the door switch 8 is closed, the flow for operating the security device 3 (step 87
04).

It goes without saying that this operation example can also be explained using the functional block diagram shown in FIG. Further, the operation of the electronic lock device 2 is the same as that described in FIG. 6 above.

In short, in this example of operation, steps 5613 and 5614 are used to set the security device 3 to the operating state, or reset its operating state (steps 5701 and 87).
02) The trap is that the switch 5 must be operated in a predetermined manner. (Switch 5, of course)
When the code is input and the lock is unlocked, the operation of the security device 3 is stopped in step 5703, so the security device 3 does not operate (step 5704).

By doing this, it is possible to forget to set the security device 3 to the operating state, and each time the security device 3 is locked, the security device 3
This has the advantage of eliminating the hassle of setting the device to an operating state.

Of course, when the operation of the security device 3 is unnecessary, it goes without saying that the security device 3 may be kept in a reset state.

Note that the flowcharts of each operation described above are shown only to explain the operations of the electronic lock device 2 and the security device 3, so a portion of the operation flow is omitted.

〔Effect of the invention〕

As described above, according to the present invention, by operating a switch on a predetermined area among a plurality of switches, the switch is activated and when the door is opened, a warning sound can be emitted to notify the surroundings. This has the effect of preventing the door from being opened and preventing crimes from occurring.
