The user (for example, a returnee) hits the numeric keypad of the numeric keypad input device 21 in front of the door 13 (step 100) or uses the remote control 22 (step 1).
01) The control unit 16 inputs a door open / close control signal corresponding to its own ID code.

The CPU 45, which is in the sleep state to save power, is released from the sleep state by the ten-key input and enters the operating state (step 102).
Confirms the ID code. At this time, even when there are a plurality of users, the control unit 16 sets the ID code (No.
1 to No. 3) can be confirmed (step 1)
03-105). When the confirmation of the ID code is completed, the unlocking sound generation device 53 outputs a notification sound (for example, P (No. 1), P (P. 2),
P.P.P. (No.3)) (Steps 106-
108), the person in the room can be notified of who has returned home. When the electromagnetic solenoid 28 is energized, the plunger 29 retreats from the plunger lock hole 30, and the door 13 is unlocked (step 109).

When a person opens the door 13, a door closing detection sensor 50
Is turned off (Step 110Y), and in this state, when a continuous unlocking operation command from the continuous unlocking operation switch 51 provided for a case where a plurality of users continuously enter the room is not input. (Step 111N), and when the OFF state of the door closing detection sensor 50 continues, the user opens the door 13 and enters the room (Step 112). 1
After a lapse of 0 seconds (step 113), the door closing detection sensor 50
Then, it is detected whether or not the door 13 is closed (step 114), and if the door 13 is not in the closed state again, the defective closing buzzer 52 sounds (step 115).

When the door is closed, the closed state is 1.5
After a lapse of seconds (step 116Y), the electromagnetic solenoid 2

17). In step 110, the user sets the door 1
If 10 seconds have not elapsed after opening 3 (step 110N) and the current has passed for 10 seconds (step 118), the energization of the electromagnetic solenoid 28 is stopped, the plunger 29 is inserted into the plunger locking hole 30, and the door 13 is locked. (Step 117).

In step 111, when a continuous unlocking operation command from the continuous unlocking operation switch 51 is input (step 111Y), the CPU 45 sleeps (step 119) and the door 13 is continuously operated. Until the unlocking instruction is issued (Step 120Y), the unlocked state is maintained.

As shown in FIGS. 7 and 8, when a door open / close control signal is input by the remote controller 22 (step 101Y), the receiver 18 receives the door open / close control signal (step 121). After that, in the same manner as when the door opening / closing control signal is given by the ten-key input device 21,
After releasing the CPU 45 from the sleep state (step 1)
22), the control unit 16 checks the ID code (steps 123 to 125). At this time, even when there are a plurality of users, the ID codes (No. 1 to No. 3) of each person can be confirmed. After that, the numeric keypad input device 21
Thus, the unlocking / locking operation of the door 13 can be performed through the same steps 106 to 120 as when the door open / close control signal is input.

In this embodiment, the unlocking / locking operation can be performed by operating the lock switch 44 from the indoor side. That is, in FIG. 7 and FIG. 8, when the lock switch 44 is pressed (step 126Y), the CPU
45 is released from the sleep state (step 127),
The unlocking sound generating device 53 emits an unlocking sound (step 12).
8). After that, the ten-key input device 21 and the remote control 22
As in the case where a control signal for opening and closing the door is input to the control unit 16, the door 13 can be unlocked and locked through steps 109 to 120.

Further, in the present embodiment, a control signal for opening and closing the door is input to the control unit 16 by the ten-key input device 21 or the remote controller 22, and after confirming the user's ID code (steps 103 to 105, 123 to 103). 125), when the ID code stored in the ROM 46 of the control unit 16 does not match the door open / close control signal (steps 103N to 103N).
05N, steps 123N to 125N), and if the above-described input operation is not completed even after 30 seconds or more (steps 129Y and 130Y), it is determined that the input is invalid and an alarm sound is generated by a predetermined alarm device. At the same time, input operations by the ten-key input device 21 or the remote controller 22 thereafter are not accepted (steps 131 and 132). It should be noted that the alarm may be generated by a predetermined alarm device when the above-described unauthorized input operation is performed four times, for example. In the case of input by the remote controller 22, the receiver 18 is set to intermittent reception (step 133). Then, the numeric keypad input device 2
1 or the input operation by the remote controller 22,
In order to save power, the CPU 45 is put into the sleep state again (step 134), and waits for the input of the next door opening / closing control signal.

As described above, the present invention has been described with reference to one embodiment. However, the present invention is not limited to the configuration described in the above embodiment, and is described in the claims. It also includes other embodiments and modifications that can be considered within the scope of the matters described. For example, the control unit:
