DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locked object such as a locker in a golf course or a sports club, and locks or unlocks the door or drawer by inputting a code such as a password. The present invention relates to a battery-operated electronic lock device that can be locked.

[0002]

2. Description of the Related Art In a conventional battery-operated electronic lock device of this type, as shown in FIG. 5, when a key (not shown) is operated on an operation panel b which is a code input unit exposed on a locker a. , While the arbitrarily selected password is registered, the lock d of the door c is locked,
Next, when a code corresponding to the password is input by operating a key, the door c is unlocked. When the administrator wants to clean the inside of the locker a in such a locked state, the master number e is separately used or the master number is input by operating the operation panel b. As a result, forcible unlocking is performed, and the registered personal identification number is erased as necessary, thereby initializing the battery-operated electronic lock device.

[0003] However, in order to perform the above initialization, in the prior art, the door or the like c is opened after the forcible unlocking, and
A reset key f provided on the back side of the operation panel b is provided with a master key e as shown in FIG.
By inserting a predetermined jig e 'as shown in (B), a reset switch (not shown) provided at the back thereof is pushed,
Thus, the registered password is deleted for the first time.

[0004] However, the above-described erasing operation requires a great deal of labor, particularly for workers, when there are hundreds of lockers, such as golf course lockers. You have to spend a lot of time.

On the other hand, in order to erase a registered password, an unlocking operation is performed using a master key, whereby a reset switch is operated to perform the erasing (Japanese Patent Laid-Open No. Hei 6-1994). 129144) has also been proposed. However, when using such a password erasing means, the locker for golf course members can be opened and cleaned by the administrator as described above, or forcibly unlocked by the master key for any other reason. In this case, the registered password is erased only by operating the master key.

[0006] Therefore, not only the member using the locker must register the password again, but also if the member is absent, the password is unknown unless the member is the member. If the member unlocks, but the member does not appear, a new password will be selected and registered without permission, and locking will not be possible.

Further, in the conventional battery-operated electronic lock device, as shown in FIG. 6, an operation panel b (keyboard) used as a code input means is provided.
Not only the code g as the personal identification number is arranged in a row from “0” to “9”, but also a key for operation start, a key for confirmation or cancellation (“C” or “M” in FIG. ). Therefore, not only the operation panel b cannot be miniaturized, but also it is difficult for a person who operates for the first time especially to understand which key of the above “C” or “M” should be pressed to input the password. Confusing the user.

Further, even in the conventional apparatus, a lock state detecting unit for confirming whether or not the door is locked and whether or not the door is unlocked, and a door of the locked body are closed. Or, a state detecting unit such as a door for confirming whether or not the door is opened is provided, and as shown by a lock state detecting unit h in FIG. The contact j is connected to the power supply potential m of the microcomputer k via the resistor n, is connected to the detection input port p of the microcomputer k, and the fixed contact q is grounded r.

Therefore, according to the above configuration, when the one-contact switch i is open, the detection input port p of the microcomputer k is at a high level, and when the one-contact switch i is closed next, At this time, the current is continuously supplied to the resistor n, and as a result, the life of the power supply battery used in the microcomputer k is considerably short.

[0010]

SUMMARY OF THE INVENTION The present invention examines the problems of the above-mentioned prior art. According to the first aspect, a code input section and a control circuit such as a microcomputer to which the output signal is input are provided. And a battery-operated electronic lock device having a lock mechanism unit connected thereto, wherein the control circuit unit includes code reading means, code digit counting means, temporary storage means, registration storage means, Appropriately equipped with a timing means, a comparison determination means, an unlocking signal generation means and a code erasing means,
Further, the lock operating section, the lock state detecting section, and the state detecting section such as the door provided in the lock mechanism are connected to the control circuit section appropriately.

With the above-described structure, in the present invention, when the battery-operated electronic lock device is to be forcibly unlocked by the master key as described above, it is necessary to use the master key while operating the key of the code input section. For example, at the same time, the password in the storage unit for registration can be erased by the code erasing means, and when it is desired to forcibly unlock without erasing the password, the key operation described above is not required to be used together. In this way, forcible unlocking with the erasure of the password can be performed in a short time with only a small amount of labor, and when the erasure is not desired, the key operation can be performed only by the omission of the key operation. The first purpose is to satisfy the demand.

[0012] Further, the above-mentioned structure, in particular, by adopting the clocking means and the digit counting means, the key for the code input means does not require a key for starting the operation or a key for confirmation or cancellation. It is a second object of the present invention to realize downsizing of the operation panel and to perform key operation which is extremely convenient for the user.

Next, in claim 2, the above-mentioned claim 1 is described.
In the configuration in the above, by introducing a two-point switch to the lock state detection unit and the state detection unit such as a door, and by appropriately connecting this and the comparison determination means in the control circuit unit, the two-point switch When the switching operation is performed by locking or unlocking, or opening or closing the door, the power supply battery in the control circuit unit is not consumed, so that its life is prolonged and maintenance is also reduced in labor. I'm trying to figure it out.

[0014]

In order to achieve the above object, according to the present invention, a code required for a personal identification number or the like which is exposed on a locked body and which is manually operated by each key is provided. A code input unit that can be freely output by the control unit, a control circuit unit connected to this, a lock operation unit that is connected to this control circuit unit, and that can be mechanically unlocked mechanically by a master key from the outside, and detects the locked / unlocked state A lock state detecting section and a lock mechanism section including a door or the like state detecting section for detecting the open / close state of the door or the like of the object to be locked, and the control circuit section includes an operation of the code input section. And a code reading means for reading a code which is an output signal of the code reading means. An operation is started by the activation of the code reading means, and control is performed when the counted number of digits of the code reaches a predetermined digit value. Digit counting means for outputting a signal; And a temporary storage means of the code reading the code reading means, the control signal from the digit counting means,
The storage code of the temporary storage means is transferred, and the storage means for registration, which is stored and registered in a non-storage state, and the operation is started by the activation of the code reading means, and a predetermined time is counted for each digit input of the code. When a code of a predetermined number of digits is not input within the time or when a code is input after a predetermined time has elapsed, a timer means for transmitting the stored code erasure signal to the temporary storage means; A lock signal is transmitted by a control signal of the counting means to generate a lock signal for locking the lock operating portion of the lock mechanism, and a control signal of the digit counting means is used to generate a storage code of the temporary storage means and a register for registration. A determination signal indicating a match between the two by comparison with the storage registration code of the storage means is input to the locking / unlocking signal generation means, and the unlocking signal output from the locking / unlocking signal generation means unlocks the lock operating unit. , And tablets The lock / unlock detection signal and the door / open / close detection signal sent from the lock state detection unit and the door / state detection unit in the mechanism unit are input, respectively, and the lock / unlock operation of the lock operation unit and the open / close state of the door etc. are determined. The comparison determining means for determining, and the storage registration code has been registered in the registration storage means, and the door or the like is closed and locked, and the lock operating part is forcibly unlocked by the master key, and the lock by this is unlocked. A code erasing means for receiving a forced unlocking signal from a comparing and judging means receiving a forced unlocking detection signal from the state detecting section, wherein the code erasing means receives the forced unlocking signal, and The presence of the code input by the key operation of the means is confirmed by the code reading means, so that the registration code erasing signal is input to the registration storage means, and the registration code of the registration storage means is erased by the absence of the code input. If there is no such signal, the door and other state detection unit sends a door and other closing detection signal to the comparison and determination unit, and the comparison and determination unit transmits an automatic control signal to the locking and unlocking signal generation unit, and generates the locking and unlocking signal. It is an object of the present invention to provide a battery-operated electronic lock device in which a lock operation unit is set to a locked state by a lock signal from the means.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the lock state detecting means and the state detecting means such as a door are provided.
A two-point switch for locking with a movable contact piece for locking, a fixed contact for unlocking position and a fixed contact for locking position, and a door with a movable contact piece for door, fixed contact for opening and fixed position for door, etc. The movable contact piece for lock and the movable contact piece for door etc. are connected to the comparison judging means of the control circuit unit, and the one in the two-point switch for lock and the two point switch for door etc. Each of the above-mentioned fixed contacts is grounded, and the other fixed contact is connected to a power supply potential line of a battery of the control circuit section.

[0016]

[Action] First, a code such as a personal identification number is registered.
For the door and the like of the locked body which was in the unlocked state until then, the operation of locking the door will be explained.The code input unit will output the code such as the password in the required number of digits sequentially.
At the same time that the first code is read by the code reading means, the digit counting means and the time counting means are started, and the input code is stored in the temporary storage means.

[0017] The above-mentioned time-measuring means may be such that a code of a predetermined number of digits is not input within a predetermined time for each digit input of a code after the operation is started, or a code is input after a predetermined time has elapsed. In such a case, the temporary storage means sends out a storage code erasure signal to erase the storage code input so far.

If the digit counting means has detected the sign of the predetermined number of digits before the predetermined time has elapsed, the digit counting means sends the control signal to the temporary storage means and the locking / unlocking operation. The temporary storage means, which has received the control signal, transfers the storage code to the next-stage registration storage means, and stores it in a secret number or the like. The registration code is registered. Of course, at this time, if the storage registration code has already been registered, the transfer is not performed.

Further, the locking signal from the locking / unlocking signal generating means receiving the control signal causes the lock operating portion of the lock mechanism to be in a locked state by using a solenoid or the like, and the locked state is unlocked. When trying to lock,
By the operation of the code input unit, the stored registration code such as the registered password is sequentially input.
When this code input operation is input to the temporary storage means as described above and the predetermined number of digits are input within the predetermined time without being erased, the temporary storage means reads the storage code from the registration storage means. After that, the recording code is transmitted to the comparing and judging means.

As a result, the comparing and judging means compares the above-mentioned stored code and the stored registration code, and issues a judgment signal when both match, whereby the unlocking signal is output from the unlocking signal generating means. It is sent to the operating section and can be unlocked by the operation of a solenoid or the like.

As described above, when the locking / unlocking operation of the lock operating portion is performed, it is determined whether the locking / unlocking operation has been performed, and whether the door of the locked body is closed at this time. As is known, a lock state detecting section and a door state detecting section are provided in the lock mechanism, respectively, in order to confirm whether or not the state is maintained. A signal is transmitted to the comparing and judging means. At this time, if locking or unlocking is not performed, and if a door or the like is not closed, an alarm device or the like can be operated as necessary.

Next, when it becomes necessary for an administrator such as a locker to open a door or the like due to various circumstances, so-called forced unlocking is carried out. Using a master key that is unlocked using a cylinder lock or the like provided in the lock operating section,
At this time, if the user wants to delete the registered personal identification number and the like in the storage unit for registration, the user does not only operate the master key but also uses the key operation and the key operation of the code input unit together.

That is, in the above-described forced unlocking, of course, the password is registered, the doors and the like are closed and locked, but when the master key is forcibly unlocked, the locked state is detected. The forced unlock detection signal is input to the comparing and judging means from the section, whereby the forced unlock signal is input to the code erasing means. At this time, if the operator on the manager side performs the key operation on the code input section as appropriate, the code erasing means confirms that not only the above-mentioned forced cancellation signal but also the code input from the code reading means has been input. Thus, the code erasing means causes the registration storage means to input a registration code erasing signal, whereby the stored registration code is erased.

Further, when the code input section is not operated, and thus the secret code is not erased, a door / close state detection signal is transmitted from the door / state detection section to the comparison / judgment means. From this, an automatic control signal is sent to the locking / unlocking signal means, whereby a locking signal is transmitted to the lock actuating section, the locking state is established, and the member of the locker does not need to register the password again and separately. There is no need to artificially perform the locking operation.

Next, in case of claim 2, not only the structure of claim 1 but also the two-point switch for lock and the two-point switch for door etc. are adopted as the lock state detector and the door etc. state detector, respectively. According to the illustrated embodiment, the unlocked state and the door and the like are opened and the movable contact piece for the lock is fixed to the unlocking position fixed contact, and the movable contact piece for the door and the like is fixed to the open position and the like. When conducting to the contacts, the power supply battery of the control circuit unit can transmit a high state to the comparison and judgment means, and when the lock state, the door, etc. are in the closed state, the lock movable contact piece is fixed in the locked position, respectively. When the movable contact piece for the door or the like conducts to the contact for fixing the closed position of the door or the like, the comparison judgment means is in the ground state and is in the low state, so that the power supply battery is grounded in any case. The battery is prevented from being unintentionally consumed. That.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiment. First, in the case of claim 1, a code input unit 1 and a control circuit unit 2 which can use a microcomputer or the like as shown in FIG. The code input unit 1 is exposed on a locked body 1a shown in FIG. 4 such as a locker or a desk, as is well known, and is required by a password or the like. The code 1b is configured to be freely output by manual operation of each key 1c as illustrated in FIG. 3, and the output signal 1d is connected so as to be input to the code reading means 2a in the control circuit unit 2.

The lock mechanism 3 is connected to the control circuit 2 as described later, and is configured to be mechanically unlockable from outside by a master key 3a. When the operating section 3b is locked or unlocked by the control circuit section 2, a lock state detecting section 3c capable of detecting the locked / unlocked state, and further, a door such as a door of the locked body 1a or a drawer. For example, 1e
Door and other state detector 3 for detecting the open state and the closed state
d.

The control circuit section 2 will be described below in detail with reference to FIG. 1 which is a functional block diagram showing the operation of the CPU. The code reading means 2a is activated by the input operation of the code input section 1 and outputs an output signal. 1d and digit counting means 2b
And the timer 2c start operating. Digit counting means 2b
Is used to count the number of digits per code 1b. For example, when the personal identification number is four digits, when the counted number of digits reaches a predetermined four-digit value, the control signals 2d, 2d
e and 2f are configured to output.

Further, the code 1b read by the code reading means 2a is input to the temporary storage means 2g to obtain a storage code, which is transferred by inputting the control signal 2d. Registration storage means 2h
The password is sent to the registration code, and the password is registered as the storage registration code. Of course, if the storage registration code is already registered in the storage means for registration 2h, there is no registration by the transfer. Become.

Next, the timing means 2c started as described above.
The time elapsed from the start is timed, and the code 1b of a predetermined number of digits is not input within the predetermined time each time the code 1b is input by one digit, or the predetermined time is elapsed. When the code 1b is input after the error has occurred, the storage code such as one to four digits of the temporary storage means 2g is erased, and this is transferred from the time keeping means 2c to the temporary storage means 2g. This is performed by transmitting the storage code erasure signal 2i.

Therefore, the control signals 2d, 2e and 2f from the digit counting means 2b are transmitted when the code 1b of the predetermined digit value has been inputted within the predetermined time as described above. The control signal 2e is generated by an unlocking signal generating means 2j.
And the lock signal 2k is operated to lock the lock operating section 3b of the lock mechanism 3 by a solenoid or the like to be described later. Thus, the personal identification number and the like are stored in the registration storage means 2h. Simultaneously with the registration, the lock operating portion 3b is locked, and the door 1e of the locked body 1a is locked.

Further, the control circuit section 2 includes a comparison / judgment means 2
m and a code erasing means 2n. One of the functions of the comparing and judging means 2m is to input the same code as the stored registration number, which is a registered personal identification number, from the code input unit 1 to unlock the door 1e. When a number is input and stored by the temporary storage unit 2g, the storage code and the registration storage code are input to the comparison determination unit 2m, and the two are compared and determined. The determination signal 2p is transmitted to the locking / unlocking signal generation means 2j. Thus,
The unlocking section 3b is unlocked by the unlocking signal 2q from the unlocking signal generating means 2j.

Further, the comparison judging means 2m includes a lock state detecting section 3c and a door state detecting section 3d in the lock mechanism 3.
And unlock detection signal 3f and door opening / closing detection signal 3f, respectively, transmitted from are received to determine whether the lock operation section 3b is in the locked state or the unlocked state, respectively, and the door or the like of the locked body 1a. It is determined whether 1e is in the open state or the closed state, and accordingly, when necessary, the alarm device or the like is operated when the unlocked state or the open state is performed.

Further, when an administrator such as a locker operates a cylinder lock or the like installed at a predetermined position of the locked body 1a by using the master key 3a and thereby forcibly unlocks the lock operating portion 3b, the lock is released. The forcible unlock detection signal 3g is inputted from the detected lock state detecting section 3c to the above-mentioned comparison judging means 2m, whereby the forcible unlock signal 2r is inputted from the comparison judging means 2m to the above-mentioned code erasing means 2n. .

However, at this time, if only the forcible unlocking signal 2r is transmitted to the code erasing means 2n, there is no output from the code erasing means 2n, and therefore the registration storage means 2h has already been registered. The emotional registration code is not deleted. However, when not only the forcible unlock signal 2r but also the key 1c of the code input unit 1 is operated and the arbitrary code 1b is read by the code reading means 2a, the code which confirms the code input is read. The registration code erasing means 2s is transmitted from the erasing means 2n, whereby the registered password and the like in the storage means for registration 2h are erased.

As described above, by forcibly unlocking with the master key 3a, the password can be selectively erased by a simple selection of whether or not to operate the key 1c. If the door 1e opened after the unlocking is closed, the door closing detection signal 3h from the door etc. state detecting section 3d is input to the comparing and judging means 2m, whereby the automatic locking signal 2t is received. When the locking signal 2k is transmitted from the signal generating means 2j, the lock operating unit 3b is in the locked state.

Next, a battery-type electronic device according to a second embodiment will be described with reference to FIG. 2. Here, the lock state detecting unit 3c and the door state detecting unit 3d shown in FIG. It is configured. That is, the lock state detection unit 3c uses the lock two-point switch 3i,
Symbols k and 3m denote a movable contact piece for locking, an unlocking position fixing contact and a locking position fixing contact, respectively.
The two-point switch 3n for doors and the like includes a movable contact piece 3p for doors and the like, a fixed contact 3q for opening the door and the like, and a fixed contact 3r for the closed position of the door and the like.

The movable contact piece 3j for the lock and the movable contact piece 3p for the door and the like are both connected to the comparing and judging means 2m which is a port of a microcomputer or the like, and one of the fixed contacts, that is, in the illustrated example. The unlocked position fixed contact 3k and the door or the like opened position fixed contact 3q are connected to the control circuit 2
Are connected via the resistor 2u and the power supply potential line 3s, and the other fixed contact, ie, in the illustrated example, the locked position fixed contact 3m and the closed position fixed contact 3r such as a door are both connected. Are also grounded by the ground 3t.

Therefore, according to the above configuration, when the unlocking signal is input by inputting the unlocking signal 2q to the lock operating section 3b, the movable contact piece for locking 3j contacts the unlocking position fixing contact 3k. Then, the power supply battery is applied to the comparing and judging means 2m from the power supply potential line 3s via the resistor 2u, whereby it is confirmed that the door is unlocked, and when the door 1e is opened, the door is opened. When the movable contact piece 3p for equivalence contacts the fixed contact 3q for opening the door or the like, the battery power is applied to the comparison determining means 2m via the resistor 2u, and the opening of the door 1e is confirmed.

Conversely, when the locking signal 2k is input to the lock operating portion 3b to be in the locked state, the movable locking piece 3j abuts on the locking position fixed contact 3m. The 2 m port is at a low potential, so that the locked state can be checked, and when the door 1e is closed, the movable contact piece 3p for the door etc. contacts the closed position fixed contact 3r for the door etc. In addition, the port of the comparison / determination means 2m is at a low potential, so that the closed state of the door or the like can be confirmed. Therefore, the battery power supply is grounded via the resistor 2u regardless of the unlocking, locking, and opening / closing of the door or the like as described above, thereby shortening the life of the battery or reducing the frequency of the battery. This eliminates the need for complicated maintenance.

The lock mechanism 3 may be of any mechanical construction, but in order to make it easier to understand the construction of the present invention, an example is shown in FIG. is there. That is, on the back side of the door or the like 1e,
The lock mechanism 3 is fixed, but if the door or the like 1e is closed, the door or other closing operation rod 10 comes into contact with the locked body 1a from the position shown in FIG. As a result, as shown in the same figure (A), it fluctuates against the elasticity of the return spring 11 such as a door in the direction of arrow 10A.

Further, a lock rotation plate 12 which is rotatable by operating a knob (not shown) exposed from a door 1e is provided, and a lock piece 13 is partially provided with a lock piece 13a.
And the distal end of the lock piece 13 is provided with a pin 12b of the lock rotation plate 12 with respect to the concave groove 10B provided in the closing operation rod 10 such as the door.
And a fixing pin 14 provided on the base 3A of the lock mechanism 3.
Are locked by the restoring force of the rotation spring 15 that is stretched between them.

Here, as described above, the closing operation rod 10 such as a door is used.
Fluctuates in the direction of the arrow 10A, so that the closed state shown in FIG. 4B is changed from the open state of the door 1e in FIG. 4A to the closed state shown in FIG. 4B. 1
3 is disposed at the position of the through hole 10C in the closing operation rod 10 such as a door. As a result, the lock turning plate 12 is turned by the spring force of the turning spring 15, so that the lock piece 13 moves downward through the through hole 10 </ b> C, whereby the door in the door state detecting unit 3 d is moved. The movable contact piece 3p for the door or the like of the equivalent two-point switch 3n is pushed, whereby the closing of the door or the like 1e can be confirmed.

FIG. 4B shows the door 1e as described above.
Is closed and unlocked. In this state, the lock groove 12c not provided in the lock rotation plate 12 is provided.
On the other hand, the locking end 16b of the locking plunger 16 is in the unlocked state, and therefore, the lock rotation plate 12 is in a state where it can be freely rotated by operating a knob (not shown). That is, in the unlocked state, the illustrated solenoid 17 is excited, and thus the locking plunger 16 is moved by the solenoid plunger 17a connected thereto.
In this case, the return spring 1 is fitted to the solenoid plunger 17a.
8 is pressed against the stop pin 17b and compressed.

The door and the like in FIG. 4B are closed.
In the unlocked state, the solenoid plunger 17a is pulled down as described above.
The operating end 16a bent at the lower end pushes the movable movable contact piece 3j of the two-point lock switch 3i in the above-described lock state detection section 3c, thereby confirming that the unlocked state is established. Can be done. In the figure, reference numeral 19 denotes a state in which the lock rotation plate 12 is moved from the state shown in FIG.
Is a stopper for the lock rotation plate 12, which protrudes from the base 3A,
Numeral 0 denotes a battery storage case fixed to the base 3A, whereby the locking plunger 16 is vertically movably guided by a projecting guide arm plate 16c.

Next, as described above, when the lock signal 2k is inputted to the lock operation section 3b, the excitation of the solenoid 17 is released, the solenoid plunger 17a is restored by the restoring force of the return spring 18. As a result, the locking plunger 16 moves upward, so that the locking end 16b is locked in the locking groove 12c,
The lock rotating plate 12 is in a locked state as shown in FIG. 4C, which cannot be rotated by operating the knob. When the locking state is established in this manner, the operating end 1 of the locking plunger 16 is moved.
Since 6a is separated from the lock two-point switch 3i, the locked state can be confirmed as described above.

When the forcible unlocking is to be performed by operating the master key 3a as described above, the forcible unlocking pin 21a is inserted by turning the master key 3a into the cylinder lock 21 as shown in FIG. By rotating, this pushes against the working end 16a of the locking plunger 16 and pulls it down, so that the locking end 16b is disengaged from the locking groove 12c to be in the unlocked state. Is detected by the lock two-point switch 3i. When the door 1e is to be opened, the lock piece 13 is pulled up by the rotation of the lock rotation plate 12 by operating the knob (not shown),
The closing operation rod 10 such as a door is moved by a return spring 11 such as a door.
However, the lock piece 13 returns to the left in the drawing, and
As shown in (A), the door 1e is locked by the concave groove 10B and the door 1e is opened.

[0048]

Since the present invention is constructed as described above, according to the first aspect, a code input section, a suitably configured control circuit section, and a lock mechanism section connected thereto are provided. When performing forced unlocking by the master key, it is possible to selectively perform only the forced unlocking, or to erase and initialize the password and the like together with this, and However, when trying to initialize, it is only necessary to operate the key of the code input part at the time of the forcible unlocking operation by the master key, so that the operation can be performed simply and quickly, and many lockers etc. The labor and time of the worker performing the operation can be greatly reduced.

In addition, the configuration of the control circuit unit eliminates the need for a key for operation start or a key for confirmation, etc., for the key in the code input means, so that the user is easy to use and the code input unit is used. The operation panel can be downsized.

In the electronic lock device according to the present invention, the lock state detecting section and the door state detecting section are both formed by using a two-point switch with an appropriate circuit configuration. In either case, the power supply battery in the control circuit section does not flow to ground via a resistor, so the life of the power supply battery can be extended and the labor required for replacement work can be greatly reduced. Can be.
