Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a secret electric lock operating device which is operated when unlocking an electric lock attached to a front door of a house, and more specifically, a secret code for inputting a predetermined secret code. The present invention relates to an improvement of a secret electric lock operating device of a type in which a code (a numeral or other symbol) displayed corresponding to an input key is randomly changed.

[0002]

2. Description of the Related Art As a secret electric lock operating device of this type, a total of 10 secret code input keys for inputting a secret code for unlocking an electric lock are provided, and the secret key input keys are provided on the surface of each secret code input key. It has been proposed that a total of 10 types of codes for personal identification codes "0" to "9" can be switched and displayed at random positions on a display unit composed of 7 segments or the like. With such a configuration, the position at which the code for the personal identification code is displayed can be changed each time the electric lock is unlocked, so that only the specific personal identification input key is not contaminated, and the personal identification code is protected. It is possible to improve the crime prevention property by eliminating the risk that the secret code is deciphered due to the dirt on the input key.

[0003]

However, in many cases, this type of secret electric lock operating device must be installed in a narrow place such as a gate frame, and it is required to be made as small as possible. Therefore, as described above, a total of 1
If 0 secret code input keys are provided, the size of the entire secret electric lock operating device becomes large, causing a problem. Further, it is conceivable to reduce the size of the secret code input key itself in place of such means, but such a mechanism causes a problem that the operability of the secret code input key is deteriorated and input errors frequently occur.

If the above-mentioned difficulties are solved and the secret electric lock operating device is simply downsized, the total number of secret code input keys is reduced to, for example, 4 or 5.
It is also conceivable to randomly display four types of codes “1” to “4” or five types of codes “1” to “5”.
However, in such a means, as the secret code for unlocking the electric lock, for example, only the secret code using the numbers "1" to "4" or the numbers "1" to "5" can be used. No, it is not possible to use other secret codes that use the numbers "5" or "6" to "9" and "0". With this, the user is familiar with "0"
A series of numbers (for example, "9840") using an arbitrary number out of "9" cannot be used as a secret code, and there is a disadvantage in that it is inconvenient in this respect.

The present invention has been proposed in view of the above points, and enables the secret electric lock operating device to be downsized without deteriorating the key operability such as inputting a secret code, and the range of selecting the secret code. The purpose is to properly solve the problem of narrow limitation and improve the usability of the secret electric lock operating device.

Embodiments of the present invention will be described below with reference to the drawings. [First embodiment (corresponding to claims 1, 4, and 5)] FIG. 1 is a block diagram showing a hardware configuration of a secret electric lock operating device 1 according to a first embodiment of the present invention. This secret electric lock operating device 1 is a CP corresponding to the control means according to the present invention.
U10, a storage unit 12 including an EEPROM (corresponding to the code setting means according to the present invention), a key input unit 11, a buzzer for generating a key operation sound in the key input unit 11, a so-called OK sound, an NG sound, etc. 13, a modulator 14, a demodulator 14a and the like. Here, the modulator 14 and the demodulator 14a are connected via a signal line L to an electric lock D attached to a front door or the like and an operation unit U installed in a house, and the modulator 14 is a key. It is for modulating a signal output from the CPU 10 in accordance with a key operation of the input unit 11 and transmitting it to the operation unit U. Demodulator 14
a demodulates a status signal such as an unlocking signal of the electric lock D and CP
It is input to U10.

The key input unit 11 is provided with a total of five personal identification input keys 11a to 11e and a display change key 11k having a symbol ".DELTA." On its surface. Of these, the display unit 15 including seven segments using light emitting LEDs is provided on each surface of the password input keys 11a to 11e.
a to 15e (corresponding to the display means of the present invention) are provided. The respective keys of the key input section 11 are arranged in a single vertical line, and are appropriately provided at a front position of a hard case (not shown) constituting the secret electric lock operating device 1 or the like.
Note that the CPU 10 and other circuits are all the key input unit 1
The secret electric lock operating device 1 is arranged and housed on the back side of the device 1 so that the entire width of the secret electric lock operating device 1 is as narrow as possible.

The storage unit 12 functions as a system memory for operating the CPU 10, and also stores a total of 10 numeric data (code data) of "0" to "9" used for inputting a personal identification code. Has been done.

The CPU 10 at random selects a total of 5 codes from the code data of "0" to "9" set in the storage section 12 and displays these codes in the display sections 15a to 15a-1.
5e is configured to be controlled to be randomly displayed at each position of 5e. The display content of this code is configured to be changed every time the display change key 11k is operated.

Further, when displaying such a code, the CPU 10 does not display the at random code at all positions of the five display sections 15a to 15e in total, but rather inputs it into the storage section 12 in advance and registers it. The control code is configured so that an appropriate code that matches the personal identification code (1) is always displayed at only one location. That is, for example, the secret code is "26
When it is "89", "2" is initially displayed on any one of the display portions 15a to 15e, and thereafter, "6", "8", and "9" are selected each time the display change key 11k is operated. Alternatively, the display is configured to be displayed at one random position.

As described above, in order to display the proper code that matches the secret code only at one place, the secret code must be stored in the storage unit 12 in advance.
For example, the user sets the secret electric lock operating device 1 in the secret code registration mode by a specific operation of the key input unit 11 and then registers the secret code by key input with the secret input keys 11a to 11e. You can leave it. Further, since the secret code is originally registered by operating the ten-key 2 of the operation unit U and registered in the memory of the operation unit U, the secret code data from the operation unit U is used. The secret code data may be registered in the storage unit 12 of the secret electric lock operating device 1 by transmitting it to the operating device 1 side.

The CPU 10 has the password input keys 11a-11.
When any one of e is operated, the data of the code displayed on the display section on the surface of the operated password input key is stored in the storage section 1.
When the number of digits of the code becomes the number of digits of the personal identification code (for example, 4 digits), the data of the series of codes is controlled to be transmitted and output from the modulator 14 to the operation unit U. It is configured.

Next, the operation and usage example of the secret electric lock operating device 1 having the above-mentioned configuration will be described. First, after registering a desired personal identification code (for example, “2689”) in the operation unit U, the same personal identification code is also registered in the storage unit 12 of the secret electric lock operating device 1 by the procedure described above. . Next, in order to perform the unlocking operation of the electric lock D, the numbers of the personal identification code are input from the personal identification input keys 11a to 11a.
11e may be input by operating the display changing key 11k once in the initial state.
As shown in (a), "2" is displayed on the display unit 15e of the display units 15a to 15e, for example, as the proper code of the first digit that matches the secret code. On the other display units 15a to 15d, a total of four numbers randomly extracted from numbers excluding "2" out of ten types of numbers "0" to "9" are randomly displayed. Therefore, the user can appropriately input the first digit of the personal identification code by operating the personal identification input key 11e on which the number "2" is displayed.

After the first digit code is operated as described above, if the display change key 11k is sequentially operated thereafter, as shown in FIGS. 2B to 2D, the personal identification code is input. Appropriate digit "6" for the required second to fourth digits
"8" and "9" are sequentially displayed at some place, and a series of personal identification codes can be appropriately input. This allows
The data of the number "2689" is sent from the CPU 10 to the modulator 1
4 is output, which is modulated and transmitted to the operation unit U. As a result, in the operation unit U, since this number data matches the secret code registered in advance in the operation unit U, an unlock signal is output to the electric lock D, and the electric lock D is unlocked. It will be. As described above, although the password input keys 11a to 11e are provided only for a total of four keys, the password is generated by using the password code using any one of the 10 types of numbers “0” to “9”. The lock D can be unlocked.

Further, the position where the numbers "2", "6", "8", and "9" necessary for inputting the above-mentioned personal identification code are displayed is not specified. For example, after the unlocking operation, the second

It is configured to perform a control different from the example. That is, as the first display mode, the CPU 10 displays the display units 15a to 15a as shown in FIG.
The numbers "1" to "5" are displayed on 5e. Then, when the display change key 11k is operated in this state, as the second display mode, as shown in FIG. 7B, other numbers "6" which are not displayed in the first display mode- It is configured to display "0".

In the above configuration, for example, when "2" is desired to be input as the personal identification code number, the input operation can be performed in the mode of FIG. 7 (a). If you want to enter "8" as the security code number, change the display key 11k.
By operating, the display may be switched to the mode shown in FIG. After all, in the present embodiment, the key input unit 11
If B is switched to any one of the display modes of FIG. 7A and FIG. 7B, it is possible to input and operate an arbitrary number out of a total of 10 numbers from “0” to “9”. Key 11
Even if the number of a to 11e is five in total, it is possible to appropriately unlock the electric lock D by using a predetermined personal identification code created with an arbitrary number out of ten types of numbers. Steps 200 to 215 of the flowchart in FIG. 8 show the operation control procedure of the CPU 10 in the third embodiment.

[Fourth Embodiment (corresponding to claim 2)] In the third embodiment, the display switching of the display portions 15a to 15e is performed by operating the display change key 11k. The described invention is not limited thereto. For example, the two display modes shown in FIGS.
It does not matter if the timers are set so that they are automatically switched alternately. Steps 300 to 317 of the flowchart of FIG. 9 show an operation procedure of the CPU 10 when the automatic switching is executed by the timer setting.

[Fifth Embodiment (corresponding to claim 2)] FIG.

As can be understood from the above description, according to the secret electric lock operating device of the present invention as defined in claims 1 to 6, a larger number of types of code data than the total number of secret code input keys can be stored. Since it can be output to the operation unit, even if the total number of PIN input keys is small, it is possible to unlock the electric lock using the PIN code created with many types of codes. It is possible to obtain a special effect that it can be used easily. Moreover, since the total number of the password input keys is set to be smaller than the number of types of codes used for the password code, the key input operability of the password input key is kept good without reducing the size of the password input key. The effect that the whole operation device can be manufactured in a small size is obtained. As a result, it is convenient to install in a narrow place such as a pole, and when it is installed in a place that is not conspicuous such as a shadow, it can be made difficult for a third party to find and the crime prevention can be improved.

Since it is not necessary to repeatedly perform the code display switching operation many times, there is an advantage that the key operation for inputting the personal identification code becomes easy.

Further, in the present invention as set forth in claim 2, when the code is switched and displayed on each display means, a new code different from the code previously displayed on each display means is displayed. Since it is possible to prevent the inappropriate PIN code that does not match the PIN code from being repeatedly displayed on each display means, it is possible to eliminate the trouble of finding the proper code that matches the PIN code. It is possible and convenient.

According to the present invention as set forth in claim 3, the total number of the secret code input keys can be reduced to 1/2 of the total number of codes for the secret code, and the so-called two screens (one display changeover) can be used for all. Since the code for the personal identification code can be displayed, it is very easy to find an appropriate code from the codes displayed by the respective display means, and the secret electric lock operating device can be miniaturized and operated well. There is an advantage that both can be efficiently satisfied.

According to the fifth aspect of the present invention, since the plurality of secret code input keys are arranged in a vertical example, this secret electric lock operating device can be formed in a vertically elongated narrow width shape. The advantage is that it becomes even more convenient for mounting in narrow spaces such as poles.

According to the sixth aspect of the present invention, the secret electric lock operating device can be changed to the function setting mode by a specific key operation, and for example, the electric lock can be locked by turning on / off the key touch sound. Alternatively, the function setting for the unlocking operation can be variously changed according to the user's request, which is convenient.
