The pulleys 6 and 7 are in such a relationship that the left and right doors 1 are driven in opposite directions by the pulley 5 which is in contact with the door opening/closing drive motor 4. Each of the doors 1 is provided with a current collector 19 at its upper end that conducts electricity to the liquid crystal layer 15, and this current collector 19 is formed in a band shape between the door panels to prevent a person from entering the door when the door 1 is open. It has enough time to supply power to the liquid crystal layer 15 until it reaches a position where it is opened to a width that allows it to pass through, and the power supply body 20 is brought into contact with and slides on this current collector 9 to supply power, and the power supply body 20 is placed at a position where a power supply state is obtained. It is arranged. 2 is a first detection device installed in front of the door to detect a user. This first detection device 2 is a motor control device M3 that controls power for opening/closing commands to the drive motor 4.
and are connected by two signal lines. 23 is motor control device W3
This is a power line that supplies electric power that provides rotational force to the drive motor 4 based on commands from the drive motor 4. 16 is installed above the door l! ! A second detection device (such as a wall of a building) measures the speed of movement of a user coming toward the door 1, and is composed of, for example, an ultrasonic device using the Doppler effect.

Then, the first detection device! 2 outputs the detection signal, which is transmitted to the motor control device 3 via a signal line 22. Motor control bag! 3 supplies power to the drive motor 4 through the power line 23, and the drive motor 4 begins to rotate in the direction of opening the door, rotating the pulleys 6 and 7 via the pulley 5. Then, the chains 10 and 11 stretched by pulleys 6.7 and 8.9 move in opposite directions, and the door 1 is opened. When the door opens, the motor control device operates based on a signal from a position detection device (not shown)! 3
stops supplying power to the drive motor 4, and the drive motor 4

The motor control bag [3 supplies power in the direction of closing the door to the drive motor 4 based on the signal, and the door closes. This is detected by a position detection device (not shown).

。Next, when the user comes towards the door 1 at a speed faster than normal walking speed, the second detection device 116 measures the user's speed, and the value is transmitted to the arithmetic processing device 17 through the signal line 24. It will be done. If the arithmetic processing unit 17 estimates that there is a risk of the user colliding with the door before the door 1 opens when the user activates the first detection bag w2 from the measured value of the traveling speed, the signal is is transmitted to the power supply control device 18.

確保できる効果がある。In order to receive the signal from the first detection device 2, the arithmetic processing unit 17 reads out whether or not a command to open the door 1 has been issued to the motor control bag M3, and uses this read signal and the first detection bag. A command to control the power supply control device 18 is issued to the power supply control device 118 based on the signal from WL2. The power supply control device 18 continues to supply power to the power supply body 20 based on the command, and even if the motor control device 3 supplies power for opening the door to the drive motor 4 and the door 1 is opened, the current collector 19 As a result, power from the power supply body 20 is applied to the liquid crystal layer 15, and the door 1 changes from a closed state to an opaque state until it reaches a width that allows a visitor to pass through, thereby making it possible for the user to notice that the door 1 is present. . This makes it possible to reliably prevent users who approach the door at a pace much faster than normal walking speed from colliding with door 1, which has good transparency, due to the illusion that door 1 is not there or that it is open. It has the effect of ensuring safety.
なお、本実施例では人体の荷重によって出力信号を出す
マッドスイッチを使用しているが、超音波センサや赤外
線センサを用いてもよい。Although this embodiment uses a mud switch that outputs an output signal depending on the load of the human body, an ultrasonic sensor or an infrared sensor may also be used.
