Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a secret electric lock operating device which is operated when unlocking an electric lock attached to a front door of a house or the like.

[0002]

2. Description of the Related Art As a secret electric lock operating device of this type, a total of 10 keys "0" to "9" are used as a password input key for inputting a password code for unlocking the electric lock.
There are some with keys. However, this type of secret electric lock operating device often has to be installed in a narrow place such as a frame of a gate, and it is required to be formed as small as possible. Therefore, as described above, a total of 10
If the personal identification input key is provided, the size of the secret electric lock operating device becomes large, which causes a problem. Further, it is conceivable to reduce the size of the personal identification input key itself in place of such means, but such a means causes a problem that the operability of the personal identification input key is deteriorated and input errors frequently occur.

Therefore, in the past, a total of 1 from "0" to "9"
Rather than having 0 password input keys, as a password input key, for example, a total of 4 keys of "1" to "4" or a total of 5 keys of "1" to "5" were provided. Only a secret electric lock operating device has been proposed. According to such a configuration, the number of the password input keys is small, so that the entire size can be reduced.

[0004]

However, for example, in the case of having only four secret code input keys "1" to "4", the secret code for unlocking the electric lock is "1".
Only the personal identification code using the numbers "4" can be used, and the personal identification code using the numbers "5" to "9" and "0" cannot be used. As a result, conventionally, a series of numbers (for example, “9840”) using arbitrary numbers among “0” to “9” that a user is accustomed to cannot be used as a secret code, which is inconvenient. Was there.

The present invention has been proposed in view of the above points, and the selection of the secret code without deteriorating the key operability such as inputting the secret code or enlarging the secret electric lock operating device itself. The purpose is to widen the width and improve the usability of the secret electric lock operating device.

[0006]

A secret electric lock operating device according to the present invention, which is proposed to achieve the above object, comprises a plurality of keys for inputting a personal identification code for unlocking the electric lock. And the signal transmission means for transmitting the data of the code (number or other symbol) corresponding to the secret code input key to the operation unit of the electric lock when the secret code input key is operated. A secret electric lock operating device, comprising: setting means for assigning and setting a plurality of codes to at least one or more of the plurality of password input keys; and a plurality of codes assigned by the setting means. And a control means for controlling so that only data of a predetermined one of the plurality of codes is output from the signal transmission means when the secret code input key is operated. .

According to a second aspect of the present invention, in the secret electric lock operating device according to the first aspect of the present invention, in the configuration of the first aspect, the control means, when a password input key to which a plurality of codes are assigned is operated, It is configured to control so as to output the data of one code which is predetermined among the plurality of codes corresponding to the number of times of operation of the secret code input key.

According to a third aspect of the present invention, in the secret electric lock operating device according to the first or second aspect, a plurality of codes assigned by the setting means are displayed on the secret code input key.

According to a fourth aspect of the present invention, there is provided a secret electric lock operating device, wherein a setting means for allocating the number of digits of a personal identification code to each of a plurality of personal identification input keys, and the personal identification input key being operated. , And a control means for controlling so as to output code data for the number of digits previously assigned to the secret code input key according to the number of operations.

According to a fifth aspect of the present invention, in the secret electric lock operating device according to the present invention, in the configuration according to any one of the first to fourth aspects, a plurality of displays arranged corresponding to each of the plurality of personal identification input keys. In addition to being equipped with lamps, these indicator lights are configured so that only some of them emit light, and the positions of the indicator lights that emit light are switched sequentially in a regular or irregular manner. The means is configured to output the data of the personal identification code only when the predetermined personal identification code is keyed after the personal identification input key corresponding to the indicator lamp in the light emitting state is operated.

According to a sixth aspect of the present invention, there is provided the secret electric lock operating device according to any one of the first to fifth aspects, wherein the plurality of secret code input keys are arranged in a vertical single row. ing.

According to a seventh aspect of the present invention, in the secret electric lock operating device according to the first aspect of the present invention, each of the plurality of secret code input keys has a key code of the secret code input key. Is provided, and a detection sensor for detecting the presence or absence of the operator's finger inserted in front of this display surface. When the finger is detected by this detection sensor, the password corresponding to this detection sensor is provided. A signal indicating that the input key has been operated is input to the control means.

[0013]

In the secret electric lock operating device according to the present invention having the above-mentioned structure, a plurality of codes can be assigned to at least one or more secret code input keys, so that the secret code can be inputted. As the number of codes used for, it is possible to use more kinds of codes than the number of secret code input keys. That is, when it is desired to use a total of 10 types of numbers "0" to "9" as the code of the personal identification code, even if the total number of the personal identification input keys is less than that, for example, a total of four, this total Ten types of codes (numbers) can be assigned to the four password input keys. Further, when the password input key to which a plurality of codes are assigned in this way is operated, only the data signal of any one of the codes assigned to the password input key is controlled by the control means. Is output from the signal transmission means. That is, for example, when the numbers "1" and "5" are assigned to one predetermined password input key, when this password input key is operated, data corresponding to the number "1" or "5" is obtained. Will be output. Therefore, it is possible to output a larger number of types of code data than the total number of the password input keys to the operation unit. As a result, the total number of PIN input keys can be made smaller than the number of types of codes used for PIN code,
It is possible to reduce the space required to install the password input key.

In the secret electric lock operating device according to the present invention as defined in claim 2, as in the case of claim 1,
Since a plurality of codes can be assigned to at least one secret code input key, the number of codes used for inputting the secret code can be a larger number of codes than the number of secret code input keys. . Further, when the password input key to which a plurality of codes are assigned in this way is operated, it is preset in accordance with the number of times of operation of the password input key among the plurality of codes assigned to the password input key. Data of any one code is output. That is, for example, when the numbers "1" and "5" are assigned to one password input key, when the password input key is operated only once, the data of the number "1" is sent twice. When operated continuously, data of number "5" is output. Therefore, as a result, it is possible to output a larger number of types of code data than the total number of secret code input keys to the operation unit, and as a result, the total number of secret code input keys can be smaller than the number of types of codes used for the secret code, The installation space for the password input key can be reduced.

In the secret electric lock operating device according to the present invention as defined in claim 3, since the plurality of codes assigned to the password input key are all displayed on the password input key, the password input key is changed. You can understand at a glance what kind of code data is output when you operate,
It is possible to eliminate the need for the user to remember in advance the type of code assigned to the password input key.

In the secret electric lock operating device according to a fourth aspect of the present invention, the number of digits of the personal identification code (for example, the first digit to the fourth digit) is assigned to each of the plurality of personal identification input keys. You can Then, when the personal identification input key assigned with this number of digits is operated, it is possible to output the code data for the number of digits assigned in advance to this personal identification input key according to the number of operations. That is, if the password input key to which the first digit is assigned is operated once,
It is possible to output "1" as the code of the first digit and output "2" as the code of the first digit by operating twice. Similarly, when the password input key to which the second digit is assigned is operated, for example, when the number of operations is 5, the second digit is "5", and when it is 6, the second digit is The data of "6" can be output as the code of.
Therefore, if it is desired to use, for example, a four-digit code as the personal identification code, only four personal identification input keys are required. Can output a large number of types of code data to the operation unit. As a result, the total number of password input keys can be made smaller than the number of types of codes used for the password code, and the installation space for the password input keys can be reduced. Further, for example, in the case of inputting a four-digit personal identification code using a total of four personal identification input keys, it is necessary to sequentially operate all four personal identification input keys. Therefore, in such key operation, unlike the case where only a part of the specific security code input keys are operated, only the specific security code input keys are soiled by the operator's hands, etc., which causes the security code to be exposed to outsiders. There is no need to be known.

In the secret electric lock operating device according to the present invention as defined in claim 5, in order to properly perform the unlocking operation of the electric lock, rather than operating the personal identification input key to input the personal identification code. In the previous period, it is necessary to operate the password input key at the position where the indicator light is emitting. Therefore, since the position where such an indicator light emits is regularly or irregularly sequentially switched, when unlocking the electric lock, the password input key not used for the password input operation is also operated. Therefore, it is possible to prevent only a part of the plurality of password input keys from becoming dirty and generating a password input key that does not become dirty. Therefore, it is possible to eliminate the possibility that the secret code is perceived by an outsider due to how dirty the secret code input key is.

In the secret electric lock operating device according to a sixth aspect of the present invention, the secret electric lock operating devices are arranged in a vertical example state, so that the secret electric lock operating device has a vertically long narrow width. Therefore, it can be easily installed even in a narrow place such as a pole.

In the secret electric lock operating device according to the present invention as set forth in claim 7, a signal indicating that a predetermined secret code input key is operated is controlled by detecting a finger of the operator by a predetermined detection sensor. Since it is input to the means,
The password input key can be operated without directly touching the password input key. Therefore, it is possible to eliminate the possibility that only a specific secret code input key is stained and the secret code is decoded from the stain. Further, since the detection sensor is individually provided for each of the personal identification input keys, it is possible to considerably reduce the risk of accidentally operating another personal identification input key while trying to operate a certain personal identification input key. .

[0020]

Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment (corresponding to claim 1)] FIG. 1 shows a first embodiment of the present invention.
It is a block diagram which shows the hardware constitutions of the secret electric lock operating device 1 which concerns on an Example. The secret electric lock operating device 1 includes a CPU 10, which corresponds to the control means according to the present invention.
A storage unit 12 (corresponding to a code allocation setting unit according to the present invention) configured by an EEPROM or the like, 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, or the like. 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 1
4a demodulates a status signal such as an unlocking signal of the electric lock D to C
It is input to the PU 10.

The key input section 11 has a total of four personal identification input keys 11a to 11d, which are respectively numbered "1" to "4".
In addition to the above keys, a "Δ" key 11h that functions as an execution key or an end key for operating when issuing an execution command such as unlocking is also provided. These respective keys are arranged in a line in a vertical direction, and are appropriately provided at a front position of a hard case (not shown) that constitutes the secret electric lock operating device 1 or the like. The CPU 10 and other circuits are all arranged and housed on the back side of the key input unit 11 and manufactured 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 a table for allocating a total of 10 numbers "0" to "9" to the total of four personal identification input keys 11a to 11d. Is configured to function as well. That is, in this storage unit 12, as shown in FIG. 2, the password input key 11a to which the number "1" is attached is added.
For, assign numbers "1""5""9",
The password input key 11b with the number "2" is "2"
The numbers "6" and "0" are assigned, and similarly, "3", "7", and "4" are similarly assigned to the other password input keys 11c and 11d.
The data to which the numbers “8” are assigned are stored.

In the CPU 10, for example, the password input key 11
When a is operated, the personal identification input keys 11a to 11d can be numbered so that data of only one of the numbers "1", "5" and "9" can be output. . That is, specifically, when a predetermined key operation shown in steps 100 and 101 of the flow chart shown in FIG. 4 is performed, the secret electric lock operating device 1 can be set in the number assignment registration mode, and the secret code input key 11a. It is possible to set the data of the numbers output when the ~ 11d is operated.

FIG. 3 is an explanatory diagram showing an example of a setting method for setting data of such numbers. In this embodiment,
As shown in the figure, if the "1" password input key 11a is operated once and then the "Δ" key 11h is operated, the password input key 11a can be set as the "1" key. When the password input key 11a of "1" is operated twice, the password input key 11a is set to "5",
When operated three times, it can be set as the "9" key, and the other "2" to "4" password input keys 11b.
It is possible to set keys 11d to 11d as keys having desired numbers in the same manner. The data set in this way are stored in steps 104 and 10 of the flowchart shown in FIG.
It is registered in the storage unit 12 via 5. However, such setting of the number allocation may be performed by switching the dip switch by providing a separate dip switch in the secret electric lock operating device 1. This also applies to each of the examples described below.

Next, the operation and action of the secret electric lock operating device 1 having the above-mentioned structure will be described. First, registration of the personal identification code is performed by operating the ten-key 2 of the operation unit U shown in FIG. 1.
An arbitrary number among the numbers "0" to "9" is used.
If the secret code is "6497", for example, as shown in FIG. 5A, each of the secret code input keys 11a to 11d is "9" by the procedure shown in FIG.
The numbers “6”, “7” and “4” are set respectively.

According to the above setting, as shown in FIG. 5B, the password input keys 11a to 11d are set to "2""4""1".
When the “Δ” key 11h for executing the unlocking is operated after operating the “3” keys in sequence in order, “64”
The data of the number "97" is output from the CPU 10 to the modulator 14, which is modulated and transmitted to the operation unit U. Therefore, in the operation unit U, since this number data coincides with the secret code registered in advance, an unlocking signal is output to the electric lock D, and the electric lock D is unlocked. In this way, the password input keys 11a-
Although 11d is provided with only four in total,
The electric lock D can be unlocked by the secret code using any number out of ten types of "0" to "9".

[Second embodiment (corresponding to claim 3)] FIG.
FIG. 11 is a front view showing a key input unit 11A of the secret electric lock operating device according to the second embodiment of the present invention. In this key input unit 11A, data of assigned numbers are displayed on the respective surface portions of the password input keys 11a to 11d.
That is, all the numbers "1", "5", and "9" are additionally displayed and displayed on the password input key 11a to which the numbers "1", "5", and "9" are assigned. With such a configuration, the operator can easily understand which number each of the personal identification input keys 11a to 11d corresponds to, and it is useful for reducing erroneous operations and the like.

[Third Embodiment (corresponding to claims 1 and 3)] FIG. 7 is a front view showing a key input portion 11B of a secret electric lock operating device according to a third embodiment of the present invention. Unlike the first and second embodiments, this key input unit 11B is provided with a total of five personal identification input keys 11a to 11e, and the data of the assigned numbers are displayed on their respective surfaces. . This number can be assigned differently from the case where there are four password input keys in total. As shown in the figure, each of the password input keys 11a to 11e has two numbers (for example, the password input key). It is possible to assign "1" or "6") to 11a.

[Fourth embodiment (corresponding to claims 1 and 3)]
Is a total of five password input keys 11a to 11e shown in FIG.
7 is a flowchart showing a procedure for setting a secret code input key number in a secret electric lock operating device of a type including. In this embodiment, steps 200 to 200 in FIG.
After performing the predetermined operation shown in 203, step 204
By operating the personal identification input key corresponding to the personal identification code (personal identification number) set in advance, a desired number can be assigned to each personal identification input key 11a to 11e. That is, specifically, as shown in FIG.
When the password input key 11a displaying "6" is operated once and then the "Δ" key 11h is operated, this key 11a is set as "1". Also, this password input key 11
When a is operated twice, “6” is set. It is possible to set desired numbers for the other personal identification input keys 11b to 11e in the manner shown in FIG. When setting this number, for example, when the personal identification number is "7140", the personal identification input keys 11a to 11e are operated so as to key in the "7140". That is, "2.
7 ”,“ 2.7 ”,“ △ ”,“ 1.6 ”,“ 1.6 ”,“ △ ”,“ 4 ”
When the key operation of “9” “Δ” “5.0” “5.0” “Δ” is performed, the number “7140” is input and set.

When the number "7140" is set as described above, a table as shown in FIG. 10 is created in the storage unit 12. In this table,
Only when the "2.7" PIN input key 11b is operated as the first digit and when the "5.0" PIN input key 11e is operated as the fourth digit, "1" stands and other In some cases, it is "0". When the table shows "0", as shown in FIG. 11A, the original numbers (that is, the numbers 1 to 5) of the personal identification input keys 11a to 11e are output. It On the contrary,
In the case of "1", as shown in FIG. 11B, the conversion number (that is, the number of 6 to 9, 0) is output when each of the password input keys 11a to 11e is operated. .
Therefore, when the password input key 11b of "2.7" is operated as the first digit number, the data of the "7" number is output, but the second digit to fourth digit numbers are output. When operated as, the data of the number "7" is no longer output, but the data of "2" is output.

As described above, the password input keys 11a ...
By operating 11e to create and input a predetermined secret code number, each secret code input key 11
If desired numbers are assigned to a to 11e, thereafter, as shown in FIG. 12, for example, "2.7""1.6""4.
When a series of key operations of "9" and "5.0" are performed, the data of the secret code of "7140" is created by this, and it becomes possible to appropriately transmit this to the operation unit U.

[Fifth embodiment (corresponding to claim 2)] FIG.
FIG. 13 is an explanatory diagram showing a number allocation mode in the secret electric lock operating device according to the fifth example of the present invention.
Although the secret electric lock operating device according to the fifth embodiment is partially different in the control program of the CPU 10 for executing the number assignment, its basic hardware configuration is substantially shown in FIG. The second embodiment is similar to the first embodiment and its details are omitted for convenience.

In the fifth embodiment, for example, the numbers "1", "5" and "9" are assigned to the password input key 11a, but any of these numbers "1""5""9" is assigned. Whether to select the number is determined by the number of times the password input key 11a is operated. That is, when the password input key 11a is operated only once, the number data of "1", when it is operated twice in succession, the number data of "5" is operated when it is operated three times in succession. The number data of "9" is assigned and output. Similarly, other password input keys 11b-
Also for 11d, different number data is output according to the number of operations.

In the above structure, as shown in FIG. 14A, "2""2""4""1""1""1""3"
When the key operation of "3" is performed, the number data of "6497" is transmitted and output to the operation unit U as shown in FIG. Therefore, even in such a case, by operating the four password input keys 11a to 11d in total,
It is possible to perform an operation of inputting a personal identification code using a total of 10 types of numbers "0" to "9".

[Sixth embodiment (corresponding to claim 5)] FIG.
Is a block diagram showing a hardware configuration of a secret electric lock operating device 1A according to a sixth embodiment of the present invention, FIG. 16 (a),
(B) is an explanatory view showing a configuration of the key input unit 11D. Although the basic hardware configuration of this secret electric lock operating device 1A is common to that of the first embodiment, a display unit 15 is provided at a position on one side of each of the password input keys 11a to 11d of the key input unit 11D. A plurality of indicator lights 15a to 15d are provided respectively. These indicator lamps 15a to 15d are composed of light emitting LEDs or the like, and are always driven by the CPU 10 so that only one of the indicator lamps emits light, and the positions of the indicator lamps that emit light are in a fixed order. ,
Alternatively, it is controlled so as to be sequentially switched in an irregular order. The switching of the light emitting position of the indicator lamp is performed, for example, each time one unlocking operation is performed.

Further, the CPU 10 uses the secret code input key 1
When operating 1a to 11d and inputting a predetermined personal identification code, one of the personal identification input keys 11a to 11d corresponding to one of the indicator lamps 15a to 15d that is in a lighting state must be operated in advance. For example, the data of the predetermined secret code is not transmitted to the operation unit U for output. That is, as shown in FIG. 16A, when the CPU 10 lights the indicator lamp 15c of the indicator lamps 15a to 15d, for example, the password input key 11c corresponding to the indicator lamp 15c is first operated and then desired. Only when the input of the personal identification code is performed, the data of the personal identification code is transmitted and output to the operation unit U. On the other hand, when the secret code input key 11c is not operated, the secret code data is not transmitted and output to the operation unit U.

Secret electric lock operating device 1A having the above-mentioned configuration
Then, as described above, for example, when the indicator lamp 15c is turned on as shown in FIG. 16A, it is necessary to additionally operate the personal identification code key 11c in addition to the personal identification code input operation. During the unlocking operation, for example, the indicator lamp 15d is turned on, and thus the password input key 11d must be operated during the unlocking operation. Further, even when the unlocking operation is performed thereafter, the display position of the indicator light is switched to the indicator light 15a and the indicator light 15b in order, so that it becomes necessary to additionally operate the password input key 11a and the password input key 11b. Therefore, if the unlocking operation is repeated a number of times, eventually all the password input keys 11a to 11d will be touched regardless of the content of the password code. As a result, only a part of the four personal identification input keys 11a to 11d necessary for the input of the personal identification code is soiled, and it is possible to eliminate the possibility that the personal identification code is deciphered by an outsider from this soiling. Therefore, it is possible to ensure crime prevention.

[Seventh embodiment (corresponding to claim 4)] FIG.
FIG. 13 is an explanatory diagram showing a configuration of a key input unit 11E of the secret electric lock operating device according to the seventh embodiment of the present invention. In this embodiment, the number of digits of the personal identification code is assigned to each of the personal identification input keys 11a to 11d. For example, the personal identification input key 11a of "1" is the first digit and the personal identification input key 11b of "2". Is the second digit, and so on.
Enter the 3rd digit for each password input key 11c, 11d of "4",
The 4th digit number is assigned. When inputting the personal identification code, when the personal identification input key 11a of "1" is operated once, the numerical data of the first digit is output as "1", and when it is operated twice, the first digit of the first digit is input. When each of the personal identification input keys 11a to 11d is operated such that the numerical data is output as "2", the data of the number corresponding to the number of times of operation is the number data for the number of digits assigned in advance. Is configured to be output as. This control is performed by the CPU 10.

In the above configuration, for example, when "2315" is input as the personal identification code, the personal identification input key 11a of "1" is operated twice to set the first digit to "2" and then "2". The password input key 11b of "3" is operated three times to set the second digit to "3".
By operating c once, the third digit is set to "1", and the password input key 11d of "4" is operated five times to set the fourth digit to "5".
As a result, as shown in FIG. 18, it is possible to input the secret code "2315" and output the secret code to the operation unit U.

According to such a structure, even with a total of four personal identification input keys 11a to 11d, the personal identification code can be keyed using four or more types of numbers, which is convenient. In addition, when inputting the four-digit personal identification code, all four personal identification input keys 11a to 11d must be operated, so that only some of the personal identification input keys become dirty. Of course, there is also an advantage that the security code can be prevented from being decrypted.

[Eighth Embodiment (corresponding to claim 7)] FIG.
2 is an external perspective view of a secret electric lock operating device 1B according to an eighth embodiment of the present invention, FIG. 20 is a sectional view taken along line XX of FIG.
1 is a block diagram showing the hardware configuration thereof. In this secret electric lock operating device 1B, as a secret input key,
The photo interrupter 16 is used. This photo interrupter 16 has a block 17 as shown in FIG.
The light emitting element 16a is disposed inside the light receiving element 16a and the light receiving element 16b is disposed inside the block 17a. The operator's finger is inserted between the light emitting and light receiving elements 16a and 16b. Then, a signal similar to that when the key switch is operated is input to the CPU 10. This photo interrupter 16 has a number “1” to
A plurality of “4” are arranged and arranged so as to correspond to the respective display surfaces 18 a to 18 d. Even in the secret electric lock operating device 1B, a plurality of codes is assigned to each secret code input key formed of the photo interrupter 16 as in the above-described embodiments.

Secret electric lock operating device 1B having the above-mentioned structure
In this case, the operator does not need to touch the display surfaces 18a to 18d at the time of inputting the personal identification code, and the input operation of the personal identification code can be performed without contact. With such an input operation method, it is possible to eliminate the risk that the personal identification code will be deciphered due to the fact that only specific portions of the display surfaces 18a to 18d are soiled. Further, since the photo interrupter 16 is individually provided for each of the display surfaces 18a to 18d, it is possible to accurately detect the finger of the operator.

Other Embodiments In each of the above-described embodiments, the case where the numbers (numerals) from “0” to “9” are used as the password has been described as an example, but the present invention is not limited to this. Of course, other numbers may be used, for example, alphabets such as “A”, “B”, “C”, etc. and other characters and symbols may be used, and the code of the personal identification code.

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 7, 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. In addition, the total number of security code input keys can be made smaller than the number of types of codes used for security code, so you can operate the security code keys with good operability without reducing the size of security code keys. The effect that the entire container can be made small 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. Can also be obtained.

Particularly, according to the present invention as set forth in claim 3,
Since the multiple code assigned to the password input key is displayed on the password input key, the user does not need to remember the type of code assigned to each password input key in advance, and erroneous memory Therefore, it is possible to eliminate the risk of operating the password input key by mistake, which is more convenient.

According to the fourth aspect of the present invention, for example, in order to input a four-digit personal identification code, only four personal identification input keys are required, so that the total number of personal identification input keys can be considerably reduced. In addition to the advantages, for example, in order to input a 4-digit personal identification code by operating the four personal identification input keys, 4
Since it is necessary to operate all of the individual PIN input keys, only certain specific PIN input keys will not be operated and will not get dirty, and the PIN code will be unfairly decrypted by an outsider from the dirt on the keys. There is also an advantage that it is possible to appropriately eliminate the fear of being caused.

According to the fifth aspect of the present invention, when the predetermined secret code is keyed to unlock the electric lock, the secret key input key at a position corresponding to the indicator light whose light emitting position is sequentially switched is used. Since it is necessary to operate, it is possible to properly eliminate the problem that only the specific secret code input key required for the secret code input is soiled, and as in the case of claim 4,
There is an advantage that it is possible to appropriately prevent the possibility that the personal identification code is decrypted due to the dirt of the personal identification input key.

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

According to the seventh aspect of the present invention, since the operator can operate the personal identification input key without directly touching the personal identification input key, the personal identification code can be deciphered from the dirt of the particular personal identification input key. You can also eliminate fear,
The advantage is that security can be enhanced.
