Reference numeral 13 denotes a registration information holding unit that holds, as registration information, information corresponding to the recorded contents of the magnetic card as a key card read by the magnetic card reader 11.

The information held in the registration information holding unit 13 is registered in advance by the device manufacturer and set by an EPROM, a fuse ROM, a Samir switch or the like. The information to be set includes a customer code, a basic code including a serial number, and a family code given in card units. For example, two pieces of first and second information are prepared. For a family of four, make two sets of magnetic cards, each consisting of four sheets, and
A family code consisting of 15 numbers is given to each card, and the first information corresponding to the contents recorded on the card of one set and the second information corresponding to the contents recorded on the other set. And are registered in the registration information storage unit 13, respectively.

Reference numeral 14 denotes an information selection circuit that selects and outputs the first and second information held in the registered information holding unit 13 according to the states of the switches 15a to 15b, and only the first information when the switch 15a is on. When the switch 15b is on, only the second information is output. When both the switches 15a and 15b are off, the first and second information are output.
When both 15b are on, the first and second information excluding the family code is output, and when the switch 15c is on, neither the first nor the second information is output.

Reference numeral 16 compares the recorded content read with the information whether or not the information corresponding to the recorded content of the magnetic card 12 read by the magnetic card reader 11 is selected by the selection circuit 14 and input from the registered information holding unit 13. This is a comparison / determination unit for making a determination. A lock switch 17a and an unlock switch 17b provided outside the house adjacent to the magnetic card reader 11 are connected to the comparison / decision unit 16, and when the comparison / decision result is YES, the magnetic card reader 11 detects the magnetic field. A lock signal or an unlock signal is output according to the switch 17a or 17b operated before and after reading the card 12.

Reference numeral 18 denotes an electric lock driving unit that drives the electric lock 19 to be locked / unlocked in response to a locking signal or an unlocking signal from the comparison / determination unit 16. Manual locking / unlocking switches 20a and 20b for manually locking / unlocking the electric lock 19 are connected to the electric lock drive unit 18 without using the magnetic card 12. The manual lock / unlock switches 20a and 20b are provided in the house.

The above components also include a conventional card-type electric lock device. When the magnetic card 12 is inserted into the card insertion slot of the magnetic card reader 11 and read, and the lock switch 17a or the unlock switch 17b is operated, the read operation is performed. The recorded contents of the magnetic card 12 thus obtained and the information from the registered information holding unit 13 are compared by the comparison / judgment unit 16 to judge whether or not there is information having a predetermined relationship. When there is corresponding information, the comparison determination unit 16 outputs a locking signal or an unlocking signal, and the electric lock driving unit 18 operates the electric lock 19 based on the signal.

Reference numeral 22 is a telephone interface for controlling the apparatus by an arbitrary telephone 25 via a telephone line 23 and a telephone station 24. The interface 22 is an arbitrary telephone 2

With the above configuration, when a person who possesses a magnetic card as a key card notices that it has been lost, call the home or office where an electric lock that can be unlocked with the card is installed by the nearest telephone. If there is a person at home or at home, ask them to take measures to prevent the card from unlocking. This processing can be performed by selectively turning on the switches 15a to 15c connected to the selection circuit 14. For example, when the lost card has a recorded content corresponding to the first information, the switch 15 for selecting the second information by the selection circuit 14 so as to prohibit the unlocking by the first information.
It suffices to set a and 15b. Alternatively, it can be dealt with by disabling only the information corresponding to the family code of the lost card.

If the family member does not answer the phone after three ringing tones,
The following measures are taken to make it impossible to unlock the lost card by telephone when it is judged to be absent.

First, a predetermined secret code is input by operating the push button diaphragm key, and then a predetermined control code is also input by operating the push button dial key. When the push-button dial keys are pressed, frequency signals corresponding to the respective keys are generated and input to the telephone interface 22 via the telephone line 23 and telephone station 24.

When the telephone interface 22 recognizes the personal identification code input after the three ringing tones, the telephone interface 22 inputs the subsequent control code to the telephone information control 27. Telephone information control unit 2
Reference numeral 7 decodes the control code and generates a signal according to the control code. When the key card is lost, the switch 15a and the switch 15a are set so that the registration information corresponding to the key card is not input to the comparison / determination unit 16 through the selection circuit 14 for the processing for prohibiting the unlocking by the card. When the one selected by 15b is the first information, the control code for switching to the second information, the control code for excluding only the family code of the key card from the first information, or the registration information Enter the control code that disables all of the above.

After that, when returning home and unlocking, enter the secret code and the control code for unlocking by pressing the push-button dial key on the telephone near your home, unlock the electric lock 19, and then enter another person. You should hurry back before you do.

For registration information that you lost your key card and cannot use it, replace the fuse ROM with a new one.
A magnetic card corresponding to the new ROM can be used as a key card. Therefore, it is desirable to prepare in advance a pair of magnetic card and ROM with new registration information in consideration of the case where the card is lost.

In the above-mentioned embodiment, when it is worried whether or not the lock is made when going out, the lock can be made by entering the personal identification code and the control code from the destination by telephone. Therefore, the user is relieved from forgetting to lock and spending anxiety while going out.
