[0022]
The magnetic card reader 1 inserts a card on which a magnetic recording signal is recorded into the slit 2, slides the card in the longitudinal direction of the slit, and reads the magnetic recording signal by a built-in magnetic head.
[0023]
Although this is not an essential configuration of the present invention, when a magnetic card reader is used for registering a card, the card is inserted and the slide operation is performed twice.
[0024]
The address number designation device 3 is provided with push buttons 3a for each digit of the arithmetic number of the address number, and pushes each push button by the number of digits for each digit, and determines the number of times the push button 3a is pressed. It is displayed on the display 3b and input.
[0025]
In the method of inputting the address number, in addition to the method described above, a rotary knob is provided for each digit of the address number. Each rotary knob is rotated within 360 degrees, and the number and the rotation angle are set. Although there is a method of inputting a number according to the correspondence relationship with the above, the method of inputting an address number is not the gist of the present invention, and does not prevent any method.
[0026]
In FIG. 2, the right side of the chain line indicates the indoor side controller 5, which is installed, for example, inside a common doorway such as an administrator room. In the figure, the decorative cover is removed so that the inside can be seen, and the internal structure is also shown in a schematic block diagram.
[0027]
The switching device 6 selects the card registration when the registration start button 7 is pressed, and selects the electric lock control if the registration start button 7 is not pressed once or is pressed twice in succession. Act on.
[0028]
First, the case of card registration, which is the first selection, will be described.
[0029]
By pressing the registration activation button 7 once, the switching device 6 selects the card registration.
[0030]
Subsequently, the card is inserted into the upper part of the slit 2 of the magnetic card reader 1 and slides downward. The card is once pulled out of the slit, inserted again into the upper part of the slit 2, and slid downward.
[0031]
The registration controller 8 stores the read magnetic recording signal in a built-in buffer memory and waits for designation of an address number.
[0032]
Next, the holder of the card presses the push button 3a for each digit of the address number designation device 3 a required number of times to display a three-digit number on the display 3b. For example, if the address number is 724, the hundred digit push button is pressed seven times, the ten digit push button is pressed twice, and the one digit push button is pressed four times.
[0033]
After confirming that the numbers on the display 3b are correct, the user presses the registration button 4 to transfer the address number to the registration controller 8.
[0034]
The registration controller 8 checks whether the designated and transferred address number is the same as an already registered address number, and if there is no problem, accepts the address number and transfers it to the magnetic recording signal storage device 9.
[0035]
The magnetic recording signal storage device 9 stores the read magnetic recording signal in a storage area frame set in advance in a one-to-one correspondence for each address number.
[0036]
Although not shown, when deleting a registered card, after specifying an address number, the delete button built in the registration controller 8 is pressed to generate a delete signal, and the address number is deleted. Card registration can be deleted.
[0037]
Further, in the above description, the operation of reading the card is performed first, and then the operation of designating the address number is performed. However, either of the two operations may be performed first.
[0038]
Next, the case of the electric lock control, which is the second selection of the switching device 6, will be described.
[0039]
In the case of the electric lock control, there is no difference from the electric lock control method using a normal card lock, and it is not the gist of the present invention.
[0040]
If the registration start button 7 is not pressed, the switching device 6 is set to the electric lock control mode. If the registration start button is pressed by mistake, the electric lock control is selected by pressing it again.
[0041]
A person who puts the electric lock in the common door and tries to enter the inside of the building inserts the card into the upper part of the slit of the magnetic card reader 2 and slides the card downward. Thus, the magnetic recording signal is read from the card.
[0042]
Then, the signal match determination device 10 compares the read magnetic recording signal of the card with the magnetic recording signal stored and accumulated for each address number in the magnetic recording signal storage device 9. This comparison operation is performed for the address numbers of all registered cards.
[0043]
As a result of the comparison, if there is a match, the read card is recognized as a registered card, so an unlock signal is sent to the electric lock 11 and the electric lock is unlocked.
[0044]
In the present invention , the registration start button 7 is provided on the indoor controller 5. This is Ru der order to prevent the outsiders to register without permission card.
