  The door device 1 configured as described above is processed in the control device 40 as follows. The contents processed in the control device 40 will be described below with reference to the flowcharts of FIGS. FIG. 4 is a flowchart of the door body slide movement process (S10) performed by the control device 40 of the door device 1. 5 shows a flowchart of the door main body pressing process (S20), and FIG. 6 shows a flowchart of the door main body pressing restricting process (S30). These processes are performed every interrupt time (for example, 0.02 seconds).

  In the door main body slide movement process (S10) performed by the control unit 40 of the door device 1, as shown in FIG. 4, first, the control device 40 detects the door main body 10 from the external detector 45 (infrared sensor 45A). It is determined whether or not a detection signal in which a human body (in / out) is present is received (S11). In S <b> 11, if the control device 40 has not received a detection signal from the external detector 45 (infrared sensor 45 </ b> A) that there is a human body (in / out) near the door body 10 (detection contents). If it is determined, door body pressing processing (S20) is performed. Further, when the control device 40 determines from the external detector 45 (infrared sensor 45A) that it has received a detection signal indicating that a human body is present near the door body 10 (detection content), A door body pressing restriction process (S30) is performed.

  The door body pressing process (S20) is a process of bringing the closed side outer portion 10a of the door body 10 into contact with the closed side inner portion 29a of the outer frame body 29 and pressing the door body 10 into a closed doorway state. As shown in FIG. 5, first, it is determined whether or not the entrance / exit is just before the closed state (S21). Specifically, it is determined whether or not the closing side outer portion 10a of the door body 10 is approaching the closing side inner portion 29a of the outer frame body 29 to a preset distance. As this preset distance, an appropriate distance can be selected, but in this example, the closing side outer portion 10a of the door body 10 is in contrast to the closing side inner portion 29a of the outer frame body 29. When approaching to 10 mm, it is determined that the doorway is about to become a closed state. This determination (S21) is repeated every predetermined interruption time (for example, 0.02 seconds) described above until it is determined that the doorway is about to be closed.

  In S21, when it is determined that the doorway is about to enter the closed state, the control device 40 presses the closed side outer portion 10a of the door body 10 against the closed side inner portion 29a of the outer frame body 29. The drive device 30 is controlled. Specifically, the control device 40 moves the door body 10 to the outer frame by a driving force that is set to be 0.1 to 1.0 times larger than a driving force that causes the normal sliding movement of the door body 10. The drive device 30 is controlled so as to be pressed against the body 29. Thus, in this door device 1, the door body 10 is pressed against the outer frame body 29, and the space between the closed side outer portion 10 a of the door body 10 and the closed side inner portion 29 a of the outer frame body 29 is determined. In addition, a slight gap is not allowed.

  The door body pressing restricting process (S30) is a process in which the door side closed state is set in a state where the closing side outside portion 10a of the door body 10 is not pressed against the closing side inside portion 29a of the outer frame body 29 and is not pressed. Then, as shown in FIG. 6, it is first determined whether or not the entrance / exit is on the verge of closing (S31). Specifically, it is determined whether or not the closing side outer portion 10a of the door body 10 is approaching the closing side inner portion 29a of the outer frame body 29 to a preset distance. As the distance set in advance, as described above, when the closing side outer portion 10a of the door body 10 is close to the closing side inner portion 29a of the outer frame body 29 up to 10 mm, the doorway is Judged that it was close to being closed. This determination (S31) is also repeated every predetermined interruption time (for example, 0.02 seconds) described above until it is determined that the doorway is about to be closed.

In S31, when it is determined that the doorway is about to enter the closed state, the control device 40 does not press the closed side outer portion 10a of the door body 10 against the closed side inner portion 29a of the outer frame body 29. The drive device 30 to be controlled is controlled. Specifically, the control device 40 performs the sliding movement of the door body 10 when the closing side outer part a of the door body 10 approaches 10 mm with respect to the closing side inner part 29a of the outer frame body 29. The drive device 30 is controlled to stop. As a result, the door main body 10 is driven by the driving force of the driving device 30 that is set to be 0.1 to 1.0 times larger than the driving force that causes the normal sliding movement of the door main body 10. yet such is pressed against the.

The door device 1 configured as described above has the following operational effects.
That is, in the door device 1 described above, when an in / out person existing near the door body 10 is detected by the infrared sensor 45A (external detector 45), the control device 40 is closed at the entrance / exit. Immediately before entering the state, that is, when the closed side outer portion a of the door body 10 approaches 10 mm with respect to the closed side inner portion 29a of the outer frame body 29, the closed side outer portion 10a of the door body 10 is The drive device 30 is controlled so as to restrict the pressing performed by the door body 10 toward the outer frame body 29 so as to come into contact with the closed side inner portion 29 a of the outer frame body 29. As a result, the door main body 10 is not pressed against the outer frame body 29 just before the entrance / exit is closed, so that the entrance / exit existing near the door main body 10 can be moved during normal sliding movement. The door body 10 can be slid without change.
Therefore, even if the entrance / exit is likely to be closed, as long as the entrance / exit is near the door body 10, the entrance / exiter does not change the sliding movement of the door body 10 and the door body 10 is slid. Can be moved.

On the other hand, when it is detected by the infrared sensor 45A (external detector 45) that there is no entrance / exit near the door body 10, the control unit is on the verge of closing the doorway (of the door body 10). When the closing side outer part a approaches 10 mm with respect to the closing side inner part 29a of the outer frame body 29), the drive device 30 is controlled so as to press the door body 10 toward the outer frame body 29. As a result, when there is no entrance / exit who is going through the door device 1 in front of the door main body 10, the door main body 10 is pressed toward the outer frame body 29 to close the doorway.
Therefore, when the doorway is in a closed state, the outer portion 10a of the door body 10 is brought into contact with the inner portion 29a of the outer frame body 29, so that the outer portion 10a of the door body 10 and the outer frame body 29 are not spaced apart. Can be brought into close contact with each other, and it is possible to eliminate the entry of a draft or the like into the building B, which is preferable for the air conditioning in the building B.

  As described above, according to the door device 1 described above, when there is an entrance / exit in the building while being configured so that the entrance / exit can intentionally slide the door body 10, The door body 10 can be intentionally slid without changing from the normal state, and when there is no in / out person, the door body 10 is in close contact with the outer frame body 29 without any gaps, and is in a closed state suitable for air conditioning and the like. It can be made.

  The door device according to the present invention is not limited to the above-described embodiment, and can be appropriately selected and configured without departing from the spirit of the present invention. For example, the door main body provided in the door device in the above-described embodiment is composed of a single sheet. However, the door main body is not limited to this, and the doorway opens and closes by moving away from each other. Even if the door body is composed of two pieces, there is no problem.
