[Background Technique vM1 Conventionally, in this type of electric lock unlocking device, a dedicated card (for example, a magnetic card) is created separately for each product, and a different card is used to perform the unlocking operation for each product. Ta. In this way, if a special card is created for each product, the number of cards that are currently being issued generally, such as bank cards (cash cards) and credit cards, which tend to be large, will increase even further. There is,
It becomes inconvenient for users to carry their phones, and it becomes difficult to recognize which card is for which purpose.
There was a problem that made me feel very inconvenienced.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned points, and its object is to provide an unlocker for an electric lock that can be unlocked with a general card used for other purposes. The purpose of the present invention is to provide a locking device.

[Disclosure of the Invention] (Structure) The present invention includes a card reading unit that reads the identification code of a general card such as a bank card written with an identification code that identifies the card, and an identification code in which the identification code is stored in advance. an identification code comparison section that compares the identification code of the card read by the memory and the card reading section with the data stored in the comparison data memory and outputs a signal for unlocking the electric lock when they match; , an identification code registration switch that is finally operated when a new card is registered as a card for unlocking an electric lock, and an identification code read by the card reader when this separate code registration switch is operated. The present invention is equipped with an identification code registration section for registering in an identification code memory, and is capable of recording and reproducing the identification code of a new card in the identification code memory, so that the electric lock can be unlocked with this card.

(Embodiment 1) FIG. 1 is a diagram showing an embodiment of the present invention, and in this embodiment, an electric lock is unlocked using a card written with an identification code that specifies the card.

The electric lock unlocking device of this embodiment includes a card reading section 1 that reads the identification code of the card, an identification code memory 3 in which the identification code is stored in advance, and the card reading section 1.
an identification code comparison section 2 that compares the identification code of the card read by the card with the data stored in the identification code memory 3 and outputs a signal for unlocking the electric lock when they match; an identification code registration switch 4 that is operated when registering the code as a card for unlocking the electric lock;
An identification code '! which registers the identification code read by the card reading section 1 in the identification code memory 3 when the identification code registration switch 4 is operated! Consists of 1 recording part 5. Conventionally, the identification code memory 3 uses a ROM memory so that the stored data cannot be rewritten, but in this embodiment, it is configured as a RAM memory so that the data can be rewritten.

The operation will be explained below. First, the operation of registering the identification code of a new card into which the identification code for identifying the card is written in the identification code memory 3 will be explained. First, the identification code registration switch 4 is turned on. Then, by inserting the card into a card insertion slot or the like of the card reading section 1, the card reading section 1 reads the identification code written on the card. The identification code read by the card reading section 1 is registered, that is, written, in the identification code memory 3 by the register *11F55. Thereafter, when the identification code registration switch 4 is turned off, the identification code read by the card reading section 1 is input to the identification code comparison section 2, and compared with the identification code written in the separate code comparison section 3. By the way, 1! Determine whether the card inserted into the card reading unit 1 to unlock the electric lock is a registered card, and if the card is registered, output a signal to unlock the electric lock. It is. In this way, the identification code registration switch 4 and the identification code registration section 5
By making it possible to replace the data stored in the identification code memory 3, there is no need to create a dedicated card for each product (the identification code of a general card, such as a bank card, can be stored in the identification code memory 3). 3, the bank card and the card for unlocking the electric lock can be used in common, making it possible to reduce the number of cards and making it easier for the user to use. If you want to erase the identification code of a card that was recorded in this way, for example, you may want to use another card as a card for unlocking an electric lock, in this case, you can erase the identification code memory 3 as follows. The data stored in the electric lock can be erased. First, turn off the power switch (not shown) that supplies power to the electric lock unlocking device. In this state, turn off the identification code registration switch 4. By turning it on and then turning off the power switch, you can erase the data stored in the identification code memory 3. Since you can easily erase the registered data in the identification code memory 3 in this way, you can avoid losing your card. You can quickly respond to such situations.

In addition, when using a card that has a horizontal redundancy check code (LRC code) in a predetermined byte (for example, a bank card has a horizontal redundancy check code in the 72nd byte), ensure that the card identification code is registered. can be done. In other words, when the above identification code registration switch is operated and a new card is registered as an unlocking card, the value obtained by exclusive ORing the data up to one predetermined byte and the above horizontal redundancy check code are used. By providing the identification code registration unit 5 with a function of registering the identification code read by the card reading unit 1 in the identification code memory 3 when the values match, the identification code read from the card by the card reading unit 1 It is possible to determine whether or not the code is an error using the identification code registration g5, and the identification code can be registered in the identification code memory 3 only when the identification code is read correctly.

Furthermore, if the following display section is provided so that the operating state of the electric lock unlocking device can be accurately determined, the operation can be performed more reliably. The display section uses a red light emitting diode and a green light emitting diode, and when the identification code g and recording switch 4 are on, both light emitting diodes light up, and when a registerable card is inserted, the light lights up green. If you make the light emitting diode blink for 5 seconds, and if you insert a card that cannot be registered, the red light emitting diode will blink for 5 seconds, then you can accurately check by n* whether the card can be registered or not. It becomes like this. Furthermore, if you erase the data on the B-specific code (S3), when the power switch of the unlocking device is turned on, the red and green surface-emitting guides will light up because the identification code registration switch 4 is on. It can be seen that the registered data in memory 3 has been deleted from the identification code.Also, when an electric lock is unlocked by inserting a card that has already been registered, the identification code comparison section that occurs when it is determined that the card is correct. The green light emitting diode may be dimmed for 2 seconds at the 2nd output, and if the card is incorrect, the red light emitting diode may be lit for 2 seconds.

(Embodiment 2) FIG. 2 is a diagram showing another embodiment of the present invention, and this embodiment prevents crime by verifying the identification code of the card and the password code input using the numeric keypad 6. This is an attempt to improve the safety of the above.

Therefore, the electric lock unlocking device of this embodiment has a numeric keypad 6 for inputting a password for identifying the user of the card, and the dark BiE after the circuit described in the first embodiment.
A pin code memory 8 in which a code is stored in advance, and an identification code memory 3 in which the identification code is sent to an identification code comparing section 2.
When the data match, the data stored in the rril certificate code memory 8 is compared with the input code entered using the numeric keypad 6, and when they match, the signal to unlock the electric lock is sent. A pin code comparison unit 7 to output, a pin code registration switch 11 operated when registering a new card as a card for unlocking an electric lock, and a pin code registration switch 11 operated when the pin code registration switch 11 is operated. Numeric keypad 6
The password code registration section 9 registers the password entered in the password code memory 8 in the password code memory 8. In addition, in the above-mentioned embodiment, when erasing the registered data stored in the identification code memory 3, the registration switch 4 and the power switch were used, but in this embodiment, the numeric keypad 6, the identification code memory 3 and the power switch are used. The pin code memory 8 is connected to the erase switch 12 and the erase switch 12 through the erase switch 13, respectively.
．． The registered data can be erased by closing 13 and inputting a special erasure code using the numeric keypad 6. In addition, the pin code comparison section 7 output is used to unlock the electric lock and the output section 1 is used to control the operation of the display section.
0 is the default.

The operation will be explained below. First, the case of registering a new card will be explained. Then, the identification code of the card is registered in the identification code memory 3 as explained in the first embodiment.

Next, the user turns on the password code registration switch 11 and inputs an appropriate password to be attached to the card using the numeric keypad 6. The input code input using the numeric keypad 6 is written into the password code memory 8 by the password code registration section 9. This allows the electric lock to be unlocked using the card and the numeric keypad 6. If the card is now inserted into the card reading section 1 and the identification code is correct, that is, the card is correct, then the password code is input using the numeric keypad 6. For example, if the PIN code is not entered using the numeric keypad 6 for a long time (for example, 20 seconds) after the card is inserted, it is not desirable from the viewpoint of security, so please input the PIN code within 20 seconds. 6
If you do not repeat the above, the numeric keypad 6 input will be passed to the PIN code comparison section 7.
However, the reception is not attached. Like this numeric keypad 6
The period during which input is accepted is indicated to the user by turning off the green light emitting diode of the first embodiment for 20 seconds, thereby indicating to the user the period during which input is possible using the numeric keypad 6.

The input code input using the numeric keypad 6 is compared with certain data registered in the password code register 8 in the password code comparison section 7. When the password codes match, the output section 10 unlocks the electric lock based on the output of the password code comparison section 7. Further, when the PIN codes do not match, the output section 10 blinks a red light emitting diode for 5 seconds in accordance with the output of the PIN code comparison section 7, thereby informing the user that the PIN code is incorrect. The registered data in the identification code memory 13 can be deleted by turning on the deletion switch 13 and, for example, inputting 9" into all digits using the numeric keypad 6. This can be done quickly if the card is lost. I can handle it.

[Effects of the Invention] As described above, the present invention includes a card reading unit that reads the identification code of a general card such as a bank card written with an identification code for identifying the card, and an identification code in which the identification code is stored in advance. Identification code comparison that compares the identification code of the card read by the code memory and the card reading section with the data stored in the identification code memory and outputs a signal to unlock the electric lock when they match. Department and
The identification code registration switch that is operated when registering a new card as a card for unlocking an electric lock, and the identification code read by the card reader when this identification code registration switch is operated are used as identification codes. Since it is equipped with an identification code registration section for registering in the memory, it is possible to turn on the identification code registration switch and use the identification code registration section to rewrite the data stored in the identification code memory.
Therefore, there is no need to create a special card for each product.
By registering the identification code of a general card, such as a bank card, in the identification code memory, the bank card and the card for unlocking electric locks can be used in common, making it possible to reduce the number of cards. As a result, the number of cards to be carried is reduced and the effort required to identify which card unlocks which electric lock is reduced, resulting in improved usability for the user. Furthermore, for the product manufacturer, there is no need to create an identification code memory with a different identification code for each product, which facilitates manufacturing.
