Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card type electric lock device.

In such an electric lock device, a code recorded on the card is read by inserting the card into a reader, and when the read code matches a pre-registered code, the electric lock can be unlocked and locked. It allows you to use complex code, which makes it safer and more secure.

[Problems to be Solved by Prior Art and Invention]

Conventionally, as such an electric lock device, while creating a dedicated magnetic card that can be read by a card reader,
In some cases, the same code as that recorded on the magnetic card is set on the card reader side by, for example, a read only memory (ROM) or a dip switch. In this conventional device, it is necessary to carry a dedicated magnetic card for locking and unlocking the electric lock.

Nowadays, many people have many cards by themselves. Therefore, if a dedicated card for the electric lock is added to this, the number of cards in hand is further increased. Carrying so many cards makes it difficult to notice even if they are lost, and this compromises safety.

Therefore, in view of the above-mentioned conventional problems, the present invention makes it possible to use an already issued card as a key card so that the electric lock can be unlocked without preparing a dedicated card. The purpose is to provide a locking device.

[Means for solving problems]

As shown in the basic configuration diagram of FIG. 1, the card-type electric lock device according to the present invention for achieving the above object has been recorded in advance for banks, credits, post offices, etc. Card-shaped storage medium 13, reading means 14 for reading the recorded contents of the card-shaped storage medium 13, registration operation means 18a manually operated when registering the recorded contents read by the reading means 14, and the registration A storage unit 17 for storing the recording content read by the reading unit when the operating unit 18a is operated, and a recording content and the storage content read by the reading unit 14 when the registration operating unit 18a is not operated. The comparing means 11a for comparing the recorded contents stored in the means 17 and outputting a signal when the two have a predetermined relationship, and the comparing means 11a. Electric lock is activated by a signal 12
It is characterized by having and.

The card-type electric lock device according to the present invention also has a telephone line 19
erasing means 11b for generating a signal for erasing the memory of the memory means 17 in response to a predetermined signal inputted through c,
Alternatively, unlocking means 11 for generating a signal for unlocking the electric lock in response to a predetermined signal input through the telephone line 19c.
c is further provided.

[Action]

In the above-mentioned configuration, when the registration operation means is manually operated, the recorded contents of the existing card-shaped storage medium 13 which is read in advance by the reading means 14, such as for bank, credit, and post office, is recorded. When the registration operation means 18a is stored in the storage means 17 and the registration operation means 18a is not operated, the recording content read by the reading means 14 by the comparing means 11a is compared with the storage content stored in the storage means 17, and both are determined to be predetermined. Since the signal is output to operate the electric lock 12 when there is a relationship, the existing card-shaped storage medium can be used as a key card.

Further, since the erasing means 11b can generate a signal for erasing the memory of the memory means 17 in response to a predetermined signal input through the telephone line 19c, the existing card-shaped memory medium used as a key card can be used. When lost, invalidation can be taken from any place.

Alternatively, since the unlocking means 11c can generate a signal for unlocking the electric lock in response to a predetermined signal input through the telephone line 19c, the existing card-shaped storage medium used as a key card is lost. Even if you don't stay home,

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the card type electric lock device according to the present invention.

The illustrated card-type electric lock device is for locking and unlocking an electric lock by using any magnetic card such as an existing bank card, credit card, or post office card created based on JIS or ISO standard. It has a control unit 11 composed of a microprocessor that operates according to a predetermined program. The control unit 11 has an electric lock 1
2, a magnetic card reader 14 as a reading means for reading the magnetic card 13, door interlocking switches 15a, 15b,
A card reader indicator 15c that indicates that the magnetic card reader 14 is readable, and a lock switch 16
a, an unlock switch 16b, a random access memory (RAM) 17 as a storage unit, an operation unit 18, a telephone interface 19, and a power supply circuit 20 are connected.

When the existing magnetic card 13 is registered as a key card or when the electric lock 12 is locked / unlocked, the magnetic card reader 14 reads the recorded contents of the magnetic card 13 inserted from the card insertion slot. The magnetic card is moved to the card reading section electrically (or manually).

The door interlocking switches 15a and 15b are turned on in association with opening / closing of an opening / closing door which is provided in the card insertion opening of the magnetic card reader 14 and prevents rainwater, dust, etc. from entering from the card insertion opening. The card reader indicator 15c indicates that the magnetic card reader 14 can read the magnetic card reader.

The lock switch 16a and the unlock switch 16b are provided in the room and are manually operated when locking and unlocking the electric lock 12 without a key card.

The RAM 17 is composed of a CMOS memory or a non-power supply memory, and has a storage capacity for storing a predetermined portion of the recorded contents of the magnetic card read by the magnetic card reader at the time of card registration, for example, about 10 cards.

The operation unit 18 is a registration / confirmation (WR / VER) key 18a used when registering a magnetic card as a key card and confirming the registration, when deleting the registration and when the number of registration and deletion operations is performed. Erase / End (DEL
/ END) key 18b, RAM for registration, deletion and confirmation
In addition to the memory position designating keys 18c and 18d used for designating the memory position in 17, a memory position indicator 18e which blinks or constantly lights a number corresponding to the designated memory position number depending on whether it is registered or not. A power-on indicator 18f, a registration indicator 18g that lights up by operating the WR / VER key 18a to indicate that the registration operation is in progress, and an erase indicator 18h that lights up by operating the DEL / END key 18b and indicates that the erase operation is in progress .

The telephone interface 19 is an arbitrary telephone 19
This is for connecting an arbitrary telephone 19a to the control unit 11 via a telephone line 19c and a telephone station 19d in response to calling a telephone 19b in the house from a. The control unit 11 connected to an arbitrary telephone 19a through the interface 19 identifies a code formed by a combination of dial sounds generated by, for example, a push button dial operation of the arbitrary telephone 19 to lock and unlock the electric lock 12. And R
Erase any registration in AM17.

The power supply circuit 20 is for rectifying and smoothing the commercial power supply AC100V and supplying a stable DC voltage to the magnetic card reader 14, the control unit 11 and the like, and is for backup so that the electric lock 12 cannot be locked or unlocked in the event of a power failure. A battery 20a is provided as a power source.

In the card-type electric lock device having the above-described configuration, after pressing the WR / VER 18a of the operation unit 18, the card such as a bank card or a credit card that is in hand is sequentially inserted into the magnetic card reader 14 to read the recorded contents. Let In response to this, the control unit 11 causes the RAM 17 to store a predetermined portion of the recorded content each time each magnetic card is read.

The recording format of the magnetic card is JIS, IOS
It is defined by a standard, and the contents to be recorded at a predetermined position of a predetermined number of bytes are predetermined to some extent.

For example, in a bank card created according to the standard called JISII type, as shown in FIG. 3 (a), a start code, an end code and a check character are recorded at bytes 1, 71 and 72, and A bank code is recorded in 11 bytes, a branch code is recorded in 12 to 15 bytes, an account number is recorded in 16 to 27 bytes, and information such as a personal identification number, a payable balance, and a payment limit is recorded by using other portions. .

On the other hand, in a credit card, a start code, an end code, and a check character are recorded at bytes 1, 71 and 72, respectively, as shown in FIG. The member number is recorded in the byte, and the personal identification number, payable balance, payment limit, etc. are recorded in other parts.

As is clear from the above, the JISII type magnetic card
Since a record including a number unique to the holder is recorded in 8 to 27 bytes, the fixed recording portion of the recorded contents read from the magnetic card is stored in the RAM 17 so that the magnetic card can be used as a key card. Can be registered as.

Although a method of storing the personal identification number in the registration is also conceivable, it is better not to use this part for registration for safety.

In addition to this, there is a type called JIS type I, but in this case as well, the same contents are recorded in 8 to 27 bytes. Therefore, type I and type II magnetic cards are mixed. But there is no problem.

FIG. 4 shows an example of the structure of the RAM 17, an area 17a consisting of 1 byte, which stores 0 to 9 memory positions, an area 17b which is provided corresponding to each position and which stores a character indicating the presence or absence of registration, and 20-byte data. Area 17c for storing

(Operation) The details of the operation performed by the control unit 11 according to a predetermined program in the above configuration will be described with reference to the flowcharts shown in FIGS.

FIG. 5 is a flow chart of the main routine in which the control unit 11 normally operates. The main routine starts when the power is turned on, various constants are set by initialization at the first step S1, and the interrupt is released at the subsequent step S2. To accept the next interrupt. After that, in step S3, it is determined whether or not there is an interrupt accepted. If the determination is NO, the process returns to step S2, and the interrupt is accepted again.

If the determination in step S3 is YES, the subsequent step S
In 4 to S7, it is determined whether the interruption is magnetic card registration, registration deletion, manual locking / unlocking, or automatic card locking / unlocking. When YES in each determination, the determination in FIGS. Go to each interrupt routine, step S7
When the determination is NO, it is determined that the operation is by telephone, and the process proceeds to the interrupt routine of FIG.

(1) Registration Operation If the determination in step S4 is YES, the procedure goes to the registration interrupt routine of FIG. The determination in step S4 is made in response to the WR / VER key 18a of the operation unit 19 being pressed.

In the registration interrupt routine of FIG. 6, in the first step S401, the registration indicator 18g is turned on, the 120-second timer is activated, and the memory position indicator 18e is displayed numerically. The number displayed on the memory position indicator 18e indicates the memory position previously specified. If the registration has already been made there, the display blinks, and if it is not registered, the display is made constantly lit. ing.

Now, when the display of the memory position indicator 18e is blinking, it is determined that the memory position has already been used for registration, and an unregistered memory position is pressed by pressing the memory position designation key 18c or 18d. Look for. That is, the designated key 18c is pressed to increase the number, and the designated key 18d is pressed to decrease the number, whereby the RAM memory positions are sequentially designated, and the number is constantly illuminated. Search for memory positions. By recording the number on the display unit at an appropriate position of the magnetic card to be registered, it can be used when the registration of the magnetic card is deleted later.

After completion of step S401, the process proceeds to step S402 where it is determined whether or not the DEL / END key 18b has been operated. If the determination in step S402 is NO, in the following step S403, it is determined whether the magnetic card reader 14 is activated and the recorded contents of the magnetic card are read. This judgment is made by judging that the reading was normally performed by the read check character.

When registering the magnetic card, the magnetic card reader 14
When the opening / closing door of is opened, the door interlock switch 1
5a is turned on, but the control unit 11 uses the door interlock switch 1
In response to the turning on of 5a, the magnetic card reader 14 is turned on to enable the magnetic card reader 14, and this is notified by the lighting of the card reader indicator 15c.

If the recorded contents of the magnetic card are normally read, step S4
When the determination result in 03 is YES, the process proceeds to step S404, and a predetermined portion of the recorded content read here,
In the magnetic card of the third format, the recording portion of 8 to 27 bytes is written and stored in the designated memory position of the RAM 17 and the memory position indicator 18
e is changed from the constant lighting to the flashing lighting.

In the subsequent step S405, it is determined whether or not the timer has overflowed 120 seconds after starting. The 120-second timer specifies the memory position for storing the record of the magnetic card to be registered within 120 seconds after its activation, and ends the registration interrupt operation unless the magnetic card reader 14 finishes the normal reading of the magnetic card. This is for automatically returning to the original main routine.

When the determination in step S405 is NO, the process proceeds to step S406, and it is determined whether or not the memory position designation key 18c is operated. When the determination in step S406 is NO, the process proceeds to step S407, where the memory position designation is performed. It is determined whether or not the key 18d is operated. When the number of magnetic cards to be registered is one, the memory position is not designated by the memory position designation key 18c or 18d, and after the registration is completed, the erase / end key 18b is pressed or any operation is performed. Leave without leaving.

In the former case, when the determinations in steps S406 and S407 are NO and the process returns to step S402, the determination in step S402 is YES, and as a result, the process proceeds to step S408 where the registration indicator 18g is turned off and the subsequent step After turning off the display 18e in S409,
Returning to step S2 of the main routine, the interrupt is released.

On the other hand, in the latter case, steps S407 to S407
When 402, S403, S405 and S406 are repeatedly executed and 120 seconds have passed and the determination in step S405 becomes YES on the way, steps S408 and S409.
Return to the main routine via.

When registering a plurality of magnetic cards, after the completion of registration of the first magnetic card is known by blinking lighting of the memory position indicator 18e, the memory position for storing the recorded content of the magnetic card to be registered next is searched for. The memory position designation key 18c or 18d is pressed. Now, if the memory position designation key 18c is operated, the determination in step S406 is YES,
As a result, the process proceeds to step S410, where the number on the position indicator 18e is incremented by 1. And the next step S
At 411, the display of the memory position indicator 18e is constantly turned on or blinked depending on whether or not the memory position has already been registered, and the subsequent step S412.
At, the 120-second timer is restarted and the time required for the registration operation for the second and subsequent sheets is set. When the memory position designation key 18d is operated, the determination in step S407 is YES, and in the subsequent step S413, the number on the position indicator 18e is decremented by 1 and then step S407.
After 411 and S412, the process returns to step S402, and the above steps are executed again.

(2) Registration Confirmation Operation So far, the case of registration has been described, but the above interrupt routine can also be used when only confirming the registration of the magnetic card at each memory position. That is, WR / V
After pressing the ER key 18a, the memory position designation key 18c or 18d is operated, and the memory position display 1
It is possible to confirm whether or not the memory position is not registered by checking whether or not the display numeral 8e blinks.

(3) Erase Operation Next, if the determination in step S5 is YES, the process proceeds to the erase interrupt routine of FIG. The determination in step S5 is performed in response to the detection that the DEL / END key 18d of the operation unit 18 has been pressed.

In the erase interrupt routine of FIG. 7, in the first step S501, the erase indicator 18h is turned on, the 120-second timer is activated, and the memory position indicator 18e is displayed numerically. Then in step S502, DEL /
It is determined whether the END key 18b has been operated. If the determination in step S502 is NO, in a succeeding step S503, it is determined whether or not the WR / VER key 18a and the DEL / END key 18b for deleting registration are simultaneously operated. If this determination is YES, in the subsequent step S504, the memory position indicator 18
The stored contents of the memory position indicated by e are cleared to delete the registration and the memory position indicator 18e which is flashing and lit is constantly lit to indicate that the magnetic card is not registered at that position. .

When the determination in step S503 is NO, step S504 is skipped and the process proceeds to step S505, in which it is determined whether the timer has overflowed 120 seconds after starting. The 120-second timer is for ending the erase interrupt operation when there is no change in the memory position to be erased for 20 seconds after its activation, and automatically returning to the main routine of FIG.

When the determination in step S505 is NO, the process proceeds to step S506, and it is determined whether or not the memory position designation key 18c is operated. When the determination in step S506 is NO, the process proceeds to step S507, where the memory position designation is performed. It is determined whether or not the key 18d is operated.

For example, when the display number of the current memory position indicator 18e is "4", the memory position to be erased is "5".
, The memory position designation key 18c is "3"
, The memory position designation key 18d is operated, so that the determination in step S506 or S507 is YES, and step S508 or S50, respectively.
9, the number on the memory position indicator 18e is incremented or decremented by 1, and the process proceeds to step S510,
The presence / absence of registration is checked here, and the memory position indicator 18e is blinked or constantly illuminated depending on the result. Then, in the next step S511, the timer is restarted.

After specifying the memory position to be erased, WR / VE
The erasing operation is performed by pressing the R key 18a and the DEL / END key 18b at the same time. If this operation is performed, the determination in step S503 is YES, and in step S504, the registration is erased and the memory position indicator 18e is displayed. The display is switched to constant lighting.

When there is one memory position to be erased, the position is not designated by the position designation key 18c or 18d thereafter, and DEL / E is set after the erasing is completed.
The ND key 18b is pressed or left without any operation.

In the former case, when the determinations in steps S506 and S507 are NO and the process returns to step S502, the determination in step S502 is YES, and as a result, the process proceeds to step S512 where the erase indicator 18h is turned off, and the subsequent step After turning off the indicator 18e at 513, the process returns to step 2 of the main routine to cancel the interrupt.

On the other hand, in the latter case, steps S507 to S507
502, S503, S505 and S506 are repeatedly executed, and when the determination in step S505 becomes YES on the way, the process returns to the main routine of FIG. 5 via steps S512 and S513.

When erasing a plurality of registrations, after the completion of the first erasure is known by constantly lighting the position indicator 18e, the memory position designation key 18c or 18d is pressed to search for the memory position to be erased next. Then, the determination in step S506 or S507 and the subsequent operation are repeated.

(4) Manual locking / unlocking The main routine (Fig. 5) is determined to be YES in step S6.
In the case of S, the routine proceeds to the manual locking / unlocking interrupt routine of FIG. The determination in step S6 is performed by pressing the lock switch 16a or the unlock switch 16b provided in the house.

In the manual locking / unlocking interrupt routine of FIG. 8, in the first step S601, it is determined whether or not the operated switch is the locking switch 16a, and if YES, the process proceeds to step S602 to output the locking signal, If NO, the process proceeds to step S603, the unlocking signal is output, and then the process returns to the main routine of FIG.

The locking signal or the unlocking signal is sent to the electric lock 12, and the electric lock 12 is accordingly brought into a state corresponding to these signals. Note that, for example, even when the electric lock 12 receives a lock signal in the locked state, the electric lock 12 does not change its state.

(5) Automatic card locking / unlocking The judgment in step S7 in the main routine of FIG. 5 is YE.
In the case of S, the routine proceeds to the automatic card locking / unlocking interrupt routine of FIG. The determination in step S7 is made in response to the turning on of the door interlocking switch 15a interlocking with the opening / closing door of the magnetic card reader 14.

In the first step S701 of the automatic card locking / unlocking interrupt routine of FIG. 9, the magnetic card reader 14 is turned on, and in the subsequent step S702, the card reader indicator 15c is turned on so that the magnetic card reader 14 can read. Instruct. Then, in step S703, a 30-second timer is started.

After activating the 30-second timer, the process proceeds to step S704, where it is determined whether the magnetic card reader 14 has finished reading the magnetic card. The determination in step S704 is Y
In the case of ES, it is determined in subsequent step S705 whether or not the reading is normally performed. This determination is made based on the read check character of the magnetic card.

The reading of the magnetic card is normally performed, and step S705 is performed.
If the determination is YES, the process proceeds to step S706, and the portion of 8 to 27 bytes used as a key item for registration is extracted from the recorded contents of the magnetic card read here. The extracted items are sequentially compared with the registration data stored in the RAM 17, and it is determined in step S707 whether or not there is a match. If YES, the process proceeds to step S708, where the memory position storing the matching registration data is set to the memory position display 18
Displayed by turning on e. After that, step S
709, lock switch 15a, unlock switch 15
It is determined which of the keys b is pressed, and if it is the lock switch 15a, the process proceeds to step S710 to output the lock signal, and if it is the unlock switch 15b, the process proceeds to step S11 to output the unlock signal.

The above is the operation when the proper key card is read by the magnetic card reader 14 within 30 seconds and the lock switch 15a or the unlock switch 15b is pressed, but the magnetic card is not read within 30 seconds, Step S7
If the determination of 04 is NO, steps S713 and S71.
4, the card reader indicator 15c is turned off and the magnetic card reader 14 is turned off, and then the process returns to the main routine of FIG.

If the magnetic card reader 14 does not read the magnetic card normally and an error occurs, step S705.
The determination is NO, the process proceeds to step S715, and it is determined whether an error has occurred three times or more before that. If the error has not occurred three times and the determination is NO, the process proceeds to step S116, the error counter is incremented by 1, and the process returns to step S704. If an error occurs even after performing the reading operation four times, the determination in step S716 becomes YES, and the flow advances to step S717, where the magnetic card reader 1
4 after ejecting the magnetic card to step S713,
After S714, the process returns to the main routine of FIG.

Even if the magnetic card reader 14 normally reads the magnetic card, if there is no registration corresponding to the read magnetic card and the determination in step S707 is NO, the steps in steps S717, S713, and S714 of FIG. Return to the main routine.

(6) Telephone operation No in step S7 in the main routine of FIG. 5
In case of, the routine proceeds to the telephone operation interruption routine of FIG. This is performed because the determinations in steps S4 to S7 are all NO although the determination that there is an interrupt is performed in step S3. The determination in step S3 is made in response to the telephone interface 19 connecting the telephone line 19c to the control unit 11.

In the telephone operation interruption routine of FIG. 10, it is determined in the first step S801 whether or not a predetermined password has been input. Password is 120
If it is not input within the predetermined time of about second and the judgment is NO,
Returning to the main routine of FIG. 5 assuming that the telephone set 19b in the home is called for another purpose. If the answering machine is also used as the telephone interface 19, the password is to press the 12 numeric keys of the push-button telephone 19a in a predetermined order following the voice "Please tell us what you need. It can be input by operating.

After this password, for example, * key, # key followed by 2
An operation code is input by pressing one of the ten keys, and this is determined in steps S802 to S804.

First, in step S802, it is determined whether or not the operation code is the lock / unlock code, and if the determination is YES, the process proceeds to step S803 to determine whether or not the lock / unlock code. If the determination in step S803 is yes, a lock signal is output in step S804 and step S804.
In 805, a corresponding voice such as “locked” is set, and in the subsequent step S806, a voice signal with the set voice is output to the telephone interface 19, and then the process returns to the main routine of FIG.

If the determination in step S803 is NO, it is determined that the code is an unlock code, the process proceeds to step S807, where an unlock signal is output, and then a voice such as "unlocked" is set in step S808. Then, after step S806, the process returns to the main routine of FIG.

When the determination in step S802 is NO, the process proceeds to step S809, in which it is determined whether the code following the password is an erase code. When the determination in step S809 is YES, it is determined in step S810 whether or not the number input after the erase code is within the memory position. If YES, in step S811, the memory position corresponding to the number is determined. Clear the memory and delete the registration. In the subsequent step S812, a voice such as "The registration of the memory position ○ has been deleted" is set, and a voice signal is output in step S806 based on the set voice, and then the process returns to the main routine of FIG.

If the erase code is different, there is no corresponding memory position, or there is no registration in the specified memory position, the determinations in steps S809 and S810 are NO, and accordingly, the process proceeds to step S813 where the code or memory is stored. After the voice indicating that the position designation is erroneous is set, a voice signal based on the set voice is output in step S806, and then the process returns to the main routine of FIG.

If the control unit 11 does not have a voice signal generating function, it is possible to easily respond by a long sound or a short sound that can be used to discriminate between acceptance and rejection of the operation code.

(Modification) In the above-described embodiment, the telephone operation is performed via the telephone interface 19 provided exclusively, but as shown by the broken line in FIG. 2, many terminals use the home bus 30. Home controller 31 connected via
Telephone interface 1 if
Instead of 9, it is also possible to connect the control unit 11 to the home bus 30 via the home bus interface 32 and perform a telephone operation via the telephone interface 33 for the home controller.

FIG. 11 shows a flowchart of the operation of the control unit 11 when operating from the home bus. That is, home bus 3
When some code is input to the control unit 11 from 0, the control unit 11 jumps from the main routine to the home bus interrupt routine, and in the first step S901, the control unit 11 determines whether or not the code is the locking / unlocking code. Judgment is YES
If it is, it is determined in step S902 whether or not it is an unlock code. When the determination in step S902 is YES, the process proceeds to step S903, an unlocking signal is output here, an unlocking code for reply to the home controller is set in subsequent step S904, and this is transmitted in step S905, and then the It returns to step S2 of the main routine of FIG.

If the determination in step S902 is NO, it is determined that the code is a lock code, the process proceeds to step S906, after outputting a lock signal here, the lock code is set in the following step S907, and this is set in the home controller in step S905. Send.

When the determination in step S901 is NO, the process proceeds to step S908, where it is determined whether the code is an erase code. If this determination is YES, the process proceeds to step S909, the memory of the designated memory position is erased, then the erase code is set in step S910, and this is transmitted to the home controller in step S905.

If the determination in step S908 is NO, it is determined that the code is incorrect and an error code is set in step S911, and this is transmitted to the home controller in step S905.

In the above example, only the telephone operation is performed via the home bus, but the operation unit 18 for registration and deletion is not directly connected to the control unit 11 but is connected to the home bus 30 and the control unit 11 is also connected. It is also possible to connect to the home bus 30 via the interface so that the electric lock 12 can be locked / unlocked, registered, erased, etc. under the control of the home controller.

[Effect]

As described above, in the card-type electric lock device according to the present invention, when the registration operation means is manually operated, pre-recorded data for the bank, the credit, the post office, etc. read by the reading means is already recorded. Since it has a storage means that can store the recorded contents of the card-shaped storage medium, it becomes possible to freely register an existing card as a key card, and it is necessary to newly create a key card by also using this card. There is no need to increase the number of cards to carry around.

Further, in the device according to the present invention, the contents of the storage means stored for recording can be erased via the telephone line, so that an accident due to the loss of the key card can be prevented when the loss is noticed.

Furthermore, in the device of the present invention, since the electric lock can be unlocked through the telephone line, it is possible to prevent the lock from being lost due to the loss of the key card.
