Reference numeral 13 denotes a code registration unit that holds a registration code corresponding to the key code picked up by the pink-up device 11. The code registration unit 13 is composed of an EPROM, a fuse ROM, a Samir switch, etc., and the code registration is performed using an electric lock. This is done in advance by the device manufacturer and the key member 1
Supplied in pairs with 2. The registration code is composed of, for example, a customer code, a basic code consisting of a manufacturing number, and a family code assigned to each key member, and the family code is assigned, for example, as a serial number of 1 to 15.

14 compares the key code of the key member 12 pink-amplified by the pickup device 11 with the code registered in the code registration section 13, and determines the validity of the key member 12 by determining whether or not the two have a predetermined correspondence relationship. This is a comparison/judgment unit that determines. The comparison/judgment section 14 includes a lock switch 15 provided outdoors adjacent to the pickup 11.
a and the unlock switch 15b are connected. The lock switch 15a and the unlock switch 15b are operated before and after the pick amplifier device 11 pinks up the key code of the key member 12. When the comparison and determination section 14 determines that the key member 12 is valid, the comparison and determination section 14 switches the switch 15.
A locking signal or an unlocking signal is output in response to the operations of a and 15b.

Reference numeral 16 denotes an electric lock driving section that locks and unlocks the electric lock 17 in response to a locking signal or an unlocking signal from the comparison/judgment section 14. A manual locking switch 18a and a manual unlocking switch 18b for manually locking and unlocking the electric lock 17 without using the key member 12 are connected to the electric lock driving section 16. The manual lock/unlock switches 18a and 18b are provided inside the house.

The above components also include a conventional electric lock device.
Insert the key member 12 into the insertion slot of the pickup device 11, pick up the key code, and lock the lock switch.
When a or unlocking switch 15b is operated, the picked up key code and the registered code from the code registration unit 13 are compared in the comparison determination unit 14, and the validity of the key member is determined depending on whether there is a predetermined relationship between the two. A determination is made.

If there is a corresponding registration code, a locking signal or an unlocking signal is output from the comparison/determination section 14, and the electric lock 17 is operated by the electric lock driving section 16 based on the signal.

20 is a telephone interface for controlling the apparatus with an arbitrary telephone 23 via a telephone line 21 and a telephone office 22. The interface 20 generates a pin code by the dial tone generated by operating the pushbutton dial key of the arbitrary telephone 23 after the ring tone generated by calling the home telephone 24 from the arbitrary telephone 23 is generated three times. In response to this input, the telephone 23 is connected to the telephone information control section 25 via the telephone line 21 and the telephone office 22. The telephone information control unit 25 identifies and decodes the control code entered manually following the password code, and generates a lock signal or an unlock signal.

In addition, 26 is a power supply circuit, which rectifies and smoothes the commercial power supply AC100 to supply a stable DC voltage to each part, and is equipped with a battery 26a as a backup power supply so that the electric lock 17 will not become impossible to lock and unlock in the event of a power outage. There is.

In the above configuration, if you are worried about whether or not you have locked the door when you go out, you can call your home from the nearest telephone 23 when you are out, and after three rings, you will receive a predetermined PIN code and the control for locking the door. The code is input by operating the pushbutton dial keys of the telephone 23. When a pushbutton dial key is operated, a frequency signal corresponding to the key is generated, and this is transmitted to the home telephone 24 and the telephone interface 20 through the telephone port vA21 and the telephone office 22.

When the telephone connected to the home telephone 24 rings three times, the telephone interface 20 holds the telephone line 21 for a certain period of time in response to this and waits for the next password to be input. When a predetermined password code is input during this fixed period of time, a circuit to the telephone code control section 25 is formed in response to this, and the subsequently input control code for treatment is directly sent to the telephone code control section 25. do.
