If the operation switch unit is operated according to a predetermined procedure, the control unit that outputs an unlock signal by marking it on the electric lock is
An i number means and an unlocking stop means are provided. This incorrect operation 8
The number 1 means is for detecting the number of erroneous operations when the operation switch section is erroneously operated without following a predetermined procedure, and the unlocking stop means is for detecting the number of erroneous operations detected by the erroneous operation R11 section. When a preset number of times is reached, the output of the unlock signal is stopped for a preset time, and each of these means can be easily implemented by incorporating, for example, a microcomputer into the control unit. can be realized.

<Configuration of Embodiment> The present invention will be specifically described below with reference to an illustrated embodiment.

The first part is a conceptual system diagram, where 1 is the operation switch part, 2
indicates a control unit, and 3 indicates an electric lock. The operation switch section 1 includes a key port switch 1a, drip-proof cover 11], etc.
In the illustrated example, the keyhole switch 1a is printed with numbers 0 to 9, a tree and the # symbol, molded in two colors, and has 12 keypresses displayed by one row of appropriate f, and these. It is composed of 12 switches installed inside each keypad corresponding to j=1, and this operation switch unit 1 is installed on the outside of the house, for example, at the entrance of a house or a doorway, or at the entrance of an office. Fortune telling is 6. In addition, increase the number of switches in [keyboard switch] a, which is u66.
The number of combinations of operating procedures such as part numbers can be increased by one; for example, in addition to the numbers 0 to 9, it is possible to use hexadecimal numbers that include the six characters ``no\'' and ``pa''.

The control unit 2 uses a built-in microcomputer to perform various controls such as detecting the opening/closing state of the door, deciphering the human input signal from the operation switch unit 1, and sending the unlock number 411 to the electric lock 3. They are installed in places where people spend a lot of time, such as the living room or kitchen in a typical home. The control section 2 is provided with a password setting switch 4, an unlock switch 5, an opening lamp 6, a power switch, a power lamp 8, and the like.

Since the password setting switch 4 can set a four-digit number using four sets of foot' switches, the figure shows an example in which the number 2352 (is set as the 1111 ID number).

The electric lock 3 is a device that can be locked into an access door or a lock 1j. When the door is closed, the latch 10 is automatically engaged and locked, and the lock is activated by an unlocking signal from the control unit 2. In addition to being unlocked, it can also be locked and unlocked using a key. Figure 2 shows an example of the internal structure of an electric lock; 3; 11 is a solenoid; :3 has a tapant, and the operation of these will be described later.

The operation switch section 1, the control section 2, and the electric lock are connected by signal lines 15a and 15b, respectively, and the control section 2 is connected to a commercial power source 16 and a pre-(It power source 17).

In addition, the indoor remote controller 1 is connected to the control unit 2 via a signal line 15c.

First, press the large key on the keyboard switch 1a.

This * key serves as a start signal key to notify the microcomputer 20 that operation of the operation switch unit 1 has begun, and also as a clear key in case the key is operated by mistake. It is now in a state where it can receive the signal from section 1. Then 2, 3, 5, 8. When the number keys are operated in the order of , the microcomputer 20 receives this human input signal and
Compare with the number set with 11" fril1 number setting switch 1. ・If it is negative, send unlock signal 81 to electric lock j).

In the electric lock: ), when the built-in latch 11 receives this signal Sl and the built-in latch 10 is pulled in and out, the reloading pin 12 is activated by the spring 1.
2a pushes the slopes 2' and 3 of the strike 22 (No. The pressure causes the ′ζ door to open. The duration of the unlocking signal 81 is set to, for example, one second, and when the signal S1 disappears, the lunch 10 returns to the round state.

When closing a door, it is best to do so with a certain amount of force, such as -1 unit.
Lunch 10 and rerotate ink pin 12 are temporarily locked with electric lock 3
When the latch 10 aligns with the hole 24 provided in the strike 22, the latch 10 is pushed out by the force of the spring Oa and locked. DayFI3 is used when locking/unlocking with a key (not shown) by engaging with the socket hole 24a. l-' +

In addition, the door and door frame are equipped with contact cables as shown in Figure 5.
'r 25a and 25b are provided respectively, and the energization of the electric 1 constant 3/\ signal is done by the Funtact set 25a + 2.
This is done only when the door is closed via 5b.

(Operation of the embodiment (2) - Personal credit card that is different from the PIN number-1;
As mentioned above, the water key on the keyboard or inch 1a is the start signal key, and if you do not press the water key, no matter how many other number keys you operate, the microcomputer 20
does not receive a human signal, and unlocking by operating the operation switch part 1 is permanently impossible.

Next, if you press the water key, the microcomputer 2
Is 0 ready to receive input signals or is it a numeric key?
If the procedure is different from the Ft fil1 number, manual signals after the digits of the different number will be ignored and the lock will not be unlocked. Then, in Microfunby 20, if the water key is pressed manually and a number different from the PIN number is entered manually, the fact that the wood key was pressed is counted as J1 as the first try, and the number of manual inputs for this water key is calculated as J1. When it reaches a preset number of times, for example 4 times, it will start the built-in timer and will not accept human input signals for the preset timer time limit, for example 15 minutes.
It is configured so that it cannot be used. In this state, the lock cannot be unlocked even if you enter ff1lchiki and 2.3.5.8 in this order by following the correct operating procedure. Therefore, even if a third party who does not know the PIN number attempts to unlock the lock by operating the operation switch section 1, if the user makes three incorrect operations, the input signal will no longer be able to be received from the next time, resulting in a crime or mischief. Unlocking is practical; it is completely prevented.

1. The number of erroneous operations and the time limit of the timer may be set to the same number and time as appropriate depending on the actual situation, such as the possibility that the owner or other legitimate person will make an input error. It was possible to count not only the water key operations, but also all V key operations, for example, Nobe 15.
They may be set the same.

In this embodiment, the built-in internal security F

As a result, those in the room can take appropriate measures, and the third party who is attempting to unlock the door can be chased away by the emergency alarm 14.

<Operation of the embodiment (3)... Unlocking from indoors> Even after the number of incorrect operations or the set value has been reached and the timer has started, the unlock switch 5 provided in the control unit 2 or the indoor remote control 18 is activated. By operating the provided unlock switch 5a, the microcomputer 20 outputs the unlock signal S, and at the same time stops the alarm signal S2.Unlocking and stopping the alarm can be done from inside the room. It is possible to do this.

Incidentally, a confirmation switch or the like may be provided to stop the alarm signal S2.

If the input from operation switch section 1 does not match the set number, for example, if the * key is pressed up to 3 times, it will return to the standby state, and the 4
The input signal is ignored after the keystroke is completed, and the timer starts and the alarm devices 27 and 28 are activated at the same time. As can be seen from the figure, if there is a human input signal while the timer is counting, the timer will be reset and restarted. Human signals continue to be ignored,
Unlocking is possible with total <1:I ratio. When the set time of the timer elapses, for example 15 minutes, the alarm device 27, 28 will stop,
Return to standby state.

Further, if the unlock switch 5.5a is opened while the timer is counting, the alarm device Ft27+28 is stopped and the main routine is returned at the same time, and the door is unlocked.

<Effects of the Invention> As mentioned above, according to the present invention, l'jf Si1
Even if a third party who does not know the predetermined procedures such as numbering attempts to unlock the door, the lock will be unlocked unless the predetermined move 11j1 is made completely by chance before reaching the preset number of times. In fact, it is possible to prevent crimes and mischief from occurring by 100% preventing a third party from unlocking the door.
