  According to the automatic door device 1 according to an embodiment of the present invention, power is supplied from the first battery 21 to the drive unit 5 in the event of a power failure, so that the door body 3 can be opened and closed even in the event of a power failure. By decelerating the speed of the door body 3 at the time from the normal time, the safety of the user M at the time of power failure is suppressed and the danger when the user M uses it is ensured. can do.

  Further, according to the automatic door device 1, the opening / closing speed of the door body 3 at the time of a power failure is adjusted based on the set value of the speed setting switch 15, so that the door body 3 can be opened / closed at a speed suitable for the situation. The safety of the user M can be improved.

  According to the automatic door device according to the present invention, the LED light 25 that illuminates the floor surface in the vicinity of the door body 3 is turned on at the time of a power failure, so that even if the floor surface or the like cannot be illuminated by another lighting tower, the user It is possible to ensure safety by suppressing the danger to M. Further, when the door body 3 is opened and closed, the safety of the user M is improved by increasing the illuminance of the LED light 25 as compared with when the door body 3 is stopped. Moreover, the 1st battery 21 can be used for a long time by making illumination intensity low at the time of a stop.

  Further, according to the automatic door device 1, since the opening / closing speed of the door body 3 is adjusted based on the set value of the speed setting switch 15 at the time of a power failure, the door body 3 can be opened / closed at a speed suitable for the situation, The safety of the user M can be improved.

  Further, according to the automatic door device 1, the door body 3 is unlocked by the electric lock 55 at the time of a power failure. For example, when the IC tag is misplaced and the IC tag detection sensor 14 cannot detect the IC tag. However, if necessary, rescuers can enter and evacuate people inside.

Further, according to the automatic door device 1, when the first battery 21 becomes lower than the set voltage during a power failure and the power supply to the drive unit 5 is switched from the first battery 21 to the second battery 22, a fire detection signal is input. In the case of being fired, the door main body 3 is moved to the open end 2B and stopped, so that the user M can secure an evacuation route without manually opening and closing the door main body 3 in the event of a fire. You can evacuate.
On the other hand, when the power supply to the drive unit 5 is switched from the first battery 21 to the second battery 22, if the smoke detection signal is input together with the fire detection signal, the door body 3 is moved to the closed end 2A. Therefore, it is possible to prevent the smoke from diffusing and filling through the opening 2H.

In addition, about the technical matter described in said embodiment, it is possible to add a various change in the range which does not deviate from the meaning of invention.
For example, in the above-described embodiment, the automatic door apparatus 1 includes the speed setting switch 15 and the case where the opening / closing speed of the door body 3 can be adjusted at the time of a power failure has been described, but the speed of the door body 3 is not adjusted. It is good also as a structure.

The movable LED light 25 is described. However, whether the LED light 25 is provided, whether the LED light 25 has either the fixed LED light 25A or the movable LED light 25, Whether or not the movable LED lights 25B are arranged on both side surfaces of the door body 3 can be arbitrarily set.

  Further, when the LED light 25 is turned on, when the door body 3 is opened and closed, the illuminance is higher than when the door body 3 is stopped by increasing or decreasing the number of light emission of the LED light emitters constituting the LED light 25. However, it is possible to arbitrarily set whether or not the illuminance of the LED light 25 can be changed and whether the illuminance change is based on increase or decrease in the number of light emission of the LED light emitters or current value. Further, a display panel or an audio output may be output together with the LED light 25 or instead of the LED light 25.

  In the above embodiment, the automatic door device 1 includes the electric lock 55. In the normal operation mode, when the IC tag detection sensor 14 detects the IC tag, the electric lock 55 is released, and the first battery mode and Although the case where the electric lock 55 is released in the second battery mode has been described, the electric lock 55 may not be provided, and the electric lock 55 may be provided in either or both of the first battery mode and the second battery mode. It is good also as composition which does not cancel. Moreover, although the case where the unlocking condition detecting means is the IC tag detection sensor 14 has been described, the unlocking condition detecting means may be constituted by other unlocking means such as a card reader or a cylinder key.

  In the above embodiment, the automatic door apparatus 1 includes the second battery 22 and switches to the second battery mode based on the voltage of the first battery 21 detected by the first battery voltage detection unit 42A at the time of a power failure. Although described, a configuration without the second battery mode may be adopted. In addition, when the second battery mode is provided, the use limit of the first battery 21 may be determined based on other indicators such as the electric capacity of the first battery 21 instead of the voltage of the first battery 21. Good.

  Moreover, in the said embodiment, although the automatic door apparatus 1 demonstrated the case where the stop position of the door main body 3 in a 2nd battery mode was set based on the detection of the fire alarm 16 and a smoke detection sensor, fire notification Whether or not to use the detection result of the detector 16 and the smoke detection sensor can be arbitrarily set where the predetermined stop position of the door body 3 is set. For example, it is good also as a structure which moves and stops the door main body 3 to the predetermined stop position (an open end, a closed end, a middle position, etc.) set beforehand, without using any detection result of a fire alarm and a smoke detection sensor. . Moreover, it is good also as a structure based on the detection result of any one of a fire detection means and a smoke detection sensor, or a structure which adds detection results other than a fire detection means and a smoke detection sensor, and sets a stop position.

  Moreover, in the said embodiment, although the 1st sensor was set to the fire alarm 16 and the 2nd sensor was a smoke detection sensor, it replaced with the fire alarm 16 and the smoke detection sensor, for example, temperature. Various sensors including a sensor may be applied.

  Moreover, in the said embodiment, although the automatic door apparatus 1 demonstrated the case where the door main body 3 opens automatically at the time of the bidirectional | two-way movement of the outer area 10 and the inner area 20, from one of the outer area 10 and the inner area 20 You may apply to the thing which the door main body 3 opens automatically, only when moving to the other.

  In the above embodiment, the proximity switch 11 includes the sensor switch 12 and the auxiliary sensor 13, and the sensor switch 12 includes, for example, the non-contact sensor 12A and the automatic door sensor 12B. The configuration can be set arbitrarily.

  Moreover, in the said embodiment, although the control part 40 demonstrated opening / closing operation | movement of the door main body 3 based on the flowchart shown in FIGS. 4-8, opening / closing of the door main body 3 based on algorithms other than the above was demonstrated. An operation may be performed.

  According to the automatic door device of the present invention, even when the supply of power is stopped due to a power failure, the user's safety is reduced while ensuring the user's convenience, and the user's safety is reduced. Therefore, it can be used industrially.
