【Example】

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a card-type electric lock 1 provided on the outside of a door a, which has a card insertion slot (hereinafter referred to as an insertion slot) 2 above it and A first light emitting element for displaying blue (hereinafter referred to as LED) and a second light emitting element for displaying red (hereinafter referred to as LED) for displaying the validity or invalidity of the insertion card are arranged side by side. A lever 3 used when opening the door a is provided below the electric lock 1. Like the well-known electric lock structure, the lever 3 can be rotated downward as indicated by an arrow when the key card inserted into the insertion slot 2 is authentic, and when the door a is pulled in this state ( Or, if pushed), the door can be opened. FIG. 2 is a block diagram showing an electrical configuration inside the electric lock 1, which is a central processing unit (CPU) that performs arithmetic processing using a system program stored in the ROM 11 and a working program stored in the RAM 12. ) 13 and this CPU
Card reader 15, which is connected to 13 via I / O unit 14,
It is composed of an LED driver 16 and a lock driver 17. The card reader 15 corresponds to an input means, and is composed of a magnetic head (not shown) provided so as to face the insertion slot 2, and is recorded on the inserted key card and a registration deletion card and a numerical card described later. It is configured to read magnetic data. When the data reading from the card such as the key card inserted into the insertion slot is completed, the LED driver 16 drives the LED to indicate that, and the data reading of the inserted card such as the key card is not possible. It is configured to drive the LEDs to flash when complete. Like the well-known card type electric lock, the lock driver 17 is configured such that when a genuine key card is inserted into the insertion slot 2, a solenoid (not shown) is actuated to rotate the lever 3. ing. In addition to the card reader 15 and the like described above, the I / O unit 14 is also connected with a sensor or the like (not shown) for detecting the open / closed state of the door a, but this is omitted because it is not directly related to the description of the present invention. There is. FIG. 3 shows a card used to delete the registration of the lost key card when the key card is lost. The registration deletion card (hereinafter referred to as deletion card) b and the numerical values 1 to 0 are used.
It is composed of ten numeric cards c _{1 to} c ₀ having the data of. The erasure card b and the numeric cards c _{1 to} c ₀ are set for each room having the door a. That is, when the room having the door a is one room in an office building and there are a plurality of occupants in the room, each occupant owns a key card having an individual registration number and One of them, for example, the manager in charge of the room stores the erasure card b and the numerical cards c _{1 to} c ₀ . The deregistration operation will be described with reference to the fourth flowchart. Now, assume that the key card with the registration number "123" is lost. Therefore, the current registration area of RAM12 is "123".
The registration number of is registered. Door a based on the declaration of the owner of the lost keycard
First, the manager in charge of the room inserts the erasure card b into the insertion slot 2 (step 100). And the erasure card b
When the data of the above is read by the card reader, the CPU 13 switches from the conventional entry control mode to the erasure mode, and that effect is displayed by lighting the LED (step 102: Yes, 10
4) Then, the erasure card b is pulled out from the insertion hole 2, and the erasure mode setting is completed (step 106). In addition, when the erasure card b is not normally inserted into the insertion slot 2 and the data of the erasure card b cannot be read for other reasons, the LED blinks and the fact is displayed. Therefore, in this case, the erasure card b is again used.
Is inserted (No at step 102, 108, 106). Next, a numeric card is inserted, but in this case, the registration numbers are inserted in order from the largest digit. That is, the numeric card c ₁ is inserted into the insertion slot 2 and when the data is read, the next numeric card c ₂ is inserted (steps 100, 112, 114, 116). Even when this numeric card is inserted, the reading state is notified as in the case of steps 104 and 108 (steps 114 and 118). When the insertion of all the numeric cards is completed, the erase card is inserted again into the insertion slot and read, and the data to be erased is set. That is, the data "123" is stored in the erased data area of the RAM 12 (Yes at step 120). Then, based on the insertion of the erasure card b again, it is checked whether or not there is registration data (“123” in this case) that matches the data stored in the deletion data area in the registration data area. The registration data is deleted. As a result, the erasure mode ends and the entry control mode is set again (step 122 positive, 124 positive, 126, 12
8). After that, entry with a key card with this deleted registration number will be refused. It should be noted that the state of insertion and reading of the erasure card b is also notified in the same manner as in steps 104, 108, 114 and 118 described above (step 12
6,128). In the device of this embodiment, the registration number can be easily erased by simply inserting the erasing card b and the numerical cards c _{1 to} c ₀ into the insertion opening 2 provided in the door a, so that the key card can be lost. It can respond promptly and can improve the security management of entry. Incidentally, in the above-mentioned embodiment, after the insertion of the numerical card,
Although the erasure card b is inserted again, this may be omitted. That is, the registration data may be deleted when the reading of the numerical value card having a predetermined number of digits is performed. However, if the erasing card is inserted again as in this embodiment, the erasing operation can be performed carefully.

[Effect of device]

In the device of the present invention, the registration number can be easily erased by simply inserting an erasure card and a numeric card into the door or the insertion port provided near the door, so that it is possible to respond immediately to the loss of the key card and to secure the entry security. Management can be improved.
