(Configuration - Opening/closing control system - First obstacle detection section)
The first obstacle detection unit 61 detects obstacles (for example, people, animals, objects, etc., hereinafter simply referred to as "obstacles") that obstruct the opening/closing movement of the first opening/closing body 20a or the second opening/closing body 20b. This is an obstacle detection means that detects obstacles. This first obstacle detection unit 61 is a known detection sensor that can set a plurality of planar obstacle detection areas in setting areas according to the open/closed states of the first opening/closing body 20a and the second opening/closing body 20b. (for example, an area sensor), etc., and as shown in FIG. 1, it is provided on the first opening/closing body 20a and is fixed to the first opening/closing body 20a with a fixture or the like. Here, in the embodiment, the "setting area" includes a fully closed setting area A1 which is an obstacle detection area in a fully closed state, and a fully open setting area A2 which is an obstacle detection area in a fully open state. It will be done.

Although the method for installing the first obstacle detection unit 61 is arbitrary, in the embodiment, as shown in FIGS. 2 and 3, the door edge side portion ( Specifically, the location is at a predetermined height (for example, about 300 mm, etc.) above the lower end of the door end side portion of the door end side opening/closing member main body 30b of the first opening/closing member 20a (on the outdoor side of the building). It is set up in With such installation, a planar obstacle detection area substantially along the horizontal direction can be set only at the predetermined height position. Furthermore, since it is not necessary to separately provide the first obstacle detection section 61 on a special support means (for example, a pole, etc.) located near the opening 3, the ease of installation of the first obstacle detection section 61 can be ensured. . Furthermore, compared to the case where the first opening/closing body 20a is provided at the door end side portion of the protruding side surface, it is possible to avoid difficulty in detecting obstacles in the fully open state, and it is possible to ensure accuracy in detecting obstacles.

Further, the setting area of the first obstacle detection unit 61 can be set in any manner, but in the embodiment, the setting area is set as follows.

That is, the fully closed setting area A1 approximately corresponds to the locus of the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b from the fully open state to the fully closed state (the trajectory shown by the imaginary line in FIG. 3(b)). It is set so as to include at least an area where the locus overlaps with the locus (that is, an area that substantially overlaps with the trajectory when viewed from the plane). Specifically, it is set with the position of the first obstacle detection unit 61 in the fully closed state as the starting point, and includes an area corresponding to the first opening/closing body 20a and the second opening/closing body 20b in the fully closed state. It is set so that there is no More specifically, as shown in FIG. 7, a detection area (not shown) of the first obstacle detection unit 61 (for example, within a predetermined distance (for example, about 8 m) from the position of the first obstacle detection unit 61) Within the detectable area (detectable area), the sensor is set to be located slightly outside the building than the opening 3, and closer to the building than the road located near the building. Further, the length of the fully closed setting area A1 in the left-right direction is approximately the same as the length from the left end of the left vertical frame member 11 to the right end of the right vertical frame member 12, and the front and rear of the fully closed setting area A1 are The length in the direction is set to be approximately the same length as the length in the front-rear direction of the first opening/closing body 20a (or second opening/closing body 20b) in the fully open state.

Further, the fully open setting area A2 is a different area from the fully closed setting area A1, and approximately corresponds to the trajectory of the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b from the fully open state to the fully closed state. It is set to include at least the area. Specifically, the position of the first obstacle detection unit 61 in the fully open state is set as the starting point (a position different from the position of the first obstacle detection unit 61 in the fully closed state), and the position of the first obstacle detection unit 61 in the fully open state is set as the starting point. It is set so as not to include the area corresponding to the first opening/closing body 20a and the second opening/closing body 20b. More specifically, as shown in FIG. 8, within the detectable area of the first obstacle detection unit 61, the sensor is located slightly inward in the left-right direction than the first opening/closing body 20a and the second opening/closing body 20b in the fully open state. It is set to be located slightly outside the building from the opening 3 and closer to the building than the road located near the building. Further, the length of the fully open setting area A2 in the left and right direction is shorter than the length of the first opening and closing body 20a and the second opening and closing body 20b in the left and right direction in the fully closed state, and the length of the fully open setting area A2 in the front and rear direction The length is set to be approximately the same as the length in the front-rear direction of the first opening/closing body 20a (or second opening/closing body 20b) in the fully open state.

By setting the setting area as described above, it becomes easier to detect obstacles that may collide with the first opening/closing body 20a or the second opening/closing body 20b in the fully closed state and the fully open state. The accuracy of detecting obstacles can be improved. In addition, in the fully closed state and the fully open state, it is possible to avoid detecting the first opening/closing body 20a, the second opening/closing body 20b, and passersby on the road as obstacles, and the first opening/closing body 20a and the second opening/closing body 20b can be prevented from being detected as obstacles. It is possible to prevent the opening/closing movement of the door from being obstructed. Furthermore, since it becomes easier to set the obstacle detection area of the first obstacle detection unit 61 according to the fully closed state and the fully open state, it becomes easier to further improve the accuracy of detecting obstacles in the fully closed state and the fully open state.

Regarding the detection operation when the first obstacle detection section 61 is an area sensor, for example, the laser light emitted from the first obstacle detection section 61 is reflected by the obstacle, and the reflected laser light is When the first obstacle detection unit 61 receives the light, it outputs a signal (hereinafter referred to as a “first obstacle detection signal”) including information indicating that an obstacle has been detected.

(Opening/closing process)
Next, the opening/closing process executed by the control section 74 of the control unit 70 in the opening/closing device 1 configured as described above will be explained. In the following description, each step is abbreviated as "S" in the description of each process shown in FIGS. 9 to 12.

The opening/closing process is a process for controlling the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b. The opening/closing process may be executed at any timing, but in the embodiment, the opening/closing process will be described as being started after the opening/closing device 1 is powered on. Note that, as described above, the first locking section 53a and the second locking section 53b perform the locking or unlocking operation based on the presence or absence of the input of the fully closed state signal or the open signal by the control unit 70. will be omitted for the sake of explanation.

When the opening/closing process is started, as shown in FIG. 9, in SA1, the opening/closing control unit 74a determines whether the opening/closing state of the first opening/closing body 20a and the second opening/closing body 20b is a fully closed state.

Although the method for determining whether or not the fully closed state is determined is arbitrary, in the embodiment, the determination is made based on whether or not the input unit 71 receives the input of the fully closed state signal, and the fully closed state is If the input of the signal is accepted, it is determined that the fully closed state is present, and if the input of the fully closed state signal is not accepted, it is determined that the fully closed state is not present.

Then, when it is determined that the opening/closing control unit 74a is in the fully closed state (SA1, Yes), the opening/closing control unit 74a shifts to fully closed state processing (SA2) (note that the first opening/closing body 20a and the second opening/closing body 20b are If the opening/closing movement is in progress, the opening/closing movement is stopped and then the process moves to fully closed state processing (SA2). If it is determined that the door is not in the fully closed state (SA1, No), the process moves to SA3. Further, after the fully closed state processing of SA2 is executed, the opening/closing control section 74a shifts to SA1. Note that the details of the fully closed state processing will be described later.

At SA3, the opening/closing control unit 74a determines whether the opening/closing states of the first opening/closing body 20a and the second opening/closing body 20b are fully open.

Although the method for determining whether the fully open state is in the fully open state is arbitrary, in the embodiment, the determination is made based on whether or not the input section 71 accepts the input of the fully open state signal, and If the input of the fully open state signal is accepted, it is determined that the fully open state is present, and if the input of the fully open state signal is not received, it is determined that the fully open state is not present.

Then, when it is determined that the opening/closing control unit 74a is in the fully open state (SA3, Yes), the opening/closing control unit 74a shifts to fully open state processing (SA4) (note that the first opening/closing body 20a and the second opening/closing body 20b move to open/close). If it is inside, the opening/closing movement is stopped and then the process moves to fully open state processing (SA4)), and if it is determined that it is not in the fully open state (SA3, No), the process moves to half open state processing (SA5). . Furthermore, after the fully open state processing of SA4 is executed, the opening/closing control section 74a shifts to SA1, and after the half open state processing of SA5 is executed, the opening/closing control section 74a shifts to SA1. The details of the fully open state process and the half open state process will be described later.

(Open/close processing - fully closed state processing)
Next, the fully closed state processing of SA2 in FIG. 9 will be explained. The fully closed state process is a process for controlling the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b corresponding to the fully closed state.

When the fully closed state processing is started, as shown in FIG. 10, at SB1, the switching unit 74b sets the obstacle detection area of the first obstacle detection unit 61 to the fully closed setting area A1 in FIG. , switching to the fully closed setting area A1 between the fully closed setting area A1 and the fully open setting area A2). Thereby, it becomes possible for the first obstacle detection unit 61 to detect an obstacle present in the fully closed setting area A1.

At SB2, the opening/closing control section 74a determines whether the input section 71 has accepted the input of the opening signal. Then, the opening/closing control unit 74a waits until it is determined that the input of the open signal is accepted (SB2, No), and when it is determined that the input of the open signal is accepted (SB2, Yes). moves to SB3.

At SB3, the opening/closing control section 74a determines whether or not an obstacle is detected based on the detection results of the first obstacle detection section 61 and the second obstacle detection section 62.

Although the method for determining whether or not this obstacle has been detected is arbitrary, in the embodiment, whether or not input of the first obstacle detection signal or the second obstacle detection signal is accepted by the input unit 71 is determined. If the input of the first obstacle detection signal or the second obstacle detection signal is accepted, it is determined that the obstacle has been detected, and the first obstacle detection signal and the second obstacle detection signal are detected. If the input of the detection signal is not accepted, it is determined that the faulty part has not been detected (the same applies to the process of SC3, which will be described later).

Then, when it is determined that an obstacle has been detected (SB3, Yes), the opening/closing control section 74a moves to SB4, and when it is determined that no obstacle has been detected (SB3, No). moves to SB5.

At SB4, the opening/closing control unit 74a continues to stop the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b regardless of whether or not the opening signal is input. After that, the opening/closing control unit 74a moves to SB2, and repeats the processing from SB2 to SB4 until it is determined in SB3 that no obstacle is detected.

At SB5, the opening/closing control unit 74a opens and moves the first opening/closing body 20a and the second opening/closing body 20b, and then ends the fully closed state process.

Although the method for controlling this opening movement is arbitrary, in the embodiment, it is controlled as follows (note that the processing at SC5 and SD4, which will be described later, is also substantially the same).

That is, when the input of the open signal is accepted at SB2, the opening movement of the first opening/closing body 20a and the second opening/closing body 20b is performed even if the reception of the input of the opening signal is not continued, and the opening movement of the first opening/closing body 20a and the second opening/closing body 20b is performed. The first opening/closing body 20a and the second opening/closing body 20b are closed until the input of a stop signal or a closing signal is accepted in the subsequent processing, or until the process of stopping the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is performed. (performing so-called "self-holding control"). As a result, when the input of the opening signal is accepted at SB2, the opening movement of the first opening/closing body 20a and the second opening/closing body 20b is performed only while the input of the opening signal is being accepted (so-called The first opening/closing body 20a and the second opening/closing body 20b can be opened/closed more easily than the "control by push-off operation"). However, the present invention is not limited to this, and control may be performed by, for example, a push-off operation.

Further, during the processing of SB2, if the input unit 71 does not accept the input of the first deceleration signal and the second deceleration signal, the first opening/closing body 20a and the second opening/closing body 20b are moved open at the normal speed. , when the input of the first deceleration signal or the second deceleration signal is accepted, the first opening/closing body 20a and the second opening/closing body are operated at a speed lower than the normal speed (for example, half the normal speed, etc.). 20b is moved open. This makes it easier to ensure safety during opening movement of the first opening/closing body 20a and the second opening/closing body 20b, and also allows the first opening/closing body 20a, the second opening/closing body 20b, the first opening/closing drive part 52a, and the second opening/closing body 20a, the second opening/closing body 20b, The load on the opening/closing drive section 52b can be reduced.

Through such fully closed state processing, the obstacle detection area of the first obstacle detection section 61 can be switched to the fully closed setting area A1, and obstacles can be detected according to the fully closed state. Therefore, obstacles can be accurately detected without hindering the opening movement of the first opening/closing body 20a and the second opening/closing body 20b.

(Open/close processing - fully open state processing)
Next, the fully open state processing of SA4 in FIG. 9 will be explained. The fully open state process is a process for controlling the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b corresponding to the fully open state.

When the fully open state process is started, as shown in FIG. (Switch to the fully open setting area A2 between the closed setting area A1 and the fully open setting area A2). Thereby, it becomes possible for the first obstacle detection unit 61 to detect an obstacle present in the fully open setting area A2.

At SC2, the opening/closing control section 74a determines whether the input section 71 has accepted the input of a closing signal. Then, the opening/closing control unit 74a waits until it is determined that the input of the closing signal is accepted (SC2, No), and when it is determined that the input of the closing signal is accepted (SC2, Yes). moves to SC3.

At SC3, the opening/closing control section 74a determines whether or not an obstacle is detected based on the detection results of the first obstacle detection section 61 and the second obstacle detection section 62. Then, the opening/closing control unit 74a shifts to SC4 when it is determined that an obstacle has been detected (SC3, Yes), and when it is determined that no obstacle has been detected (SC3, No). moves to SC5.

At SC4, the opening/closing control unit 74a continues to stop the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b, regardless of whether or not a closing signal is input. Thereafter, the opening/closing control unit 74a moves to SC2 and repeats the processing from SC2 to SC4 until it is determined in SC3 that no obstacle is detected.

At SC5, the opening/closing control unit 74a moves the first opening/closing body 20a and the second opening/closing body 20b to close, and then ends the fully open state processing.

Through such fully open state processing, the obstacle detection area of the first obstacle detection unit 61 can be switched to the fully open setting area A2, and obstacles can be detected according to the fully open state. Therefore, obstacles can be accurately detected without interfering with the closing movement of the first opening/closing body 20a and the second opening/closing body 20b.

(Opening/closing process - half-open state process)
Next, the half-open state processing of SA5 in FIG. 9 will be explained. The half-open state process is a process for controlling the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b corresponding to the half-open state (half-open/open moving state, half-open/closed moving state, or half-open/stop state).

When the half-open state process is activated, as shown in FIG. 12, the opening/closing control unit 74a in SD1 determines whether or not an obstacle is detected based only on the detection result of the second obstacle detection unit 62. do.

Although the method for determining whether or not this obstacle has been detected is arbitrary, in the embodiment, it is determined whether or not the input unit 71 receives the input of the second obstacle detection signal, and the second obstacle is detected. If the input of the object detection signal is accepted, it is determined that the obstacle is detected, and if the input of the second obstacle detection signal is not accepted, it is determined that the obstacle is not detected. judge.

Then, when it is determined that an obstacle has been detected (SD1, Yes), the opening/closing control section 74a shifts to SD2, and when it is determined that no obstacle has been detected (SD1, No), the opening/closing control section 74a shifts to SD2. moves to SD2.

In SD2, the opening/closing control unit 74a stops the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b, regardless of whether a closing signal or an opening signal is input. Specifically, when in the half-open/open movement state or the half-open/close movement state, the opening movement or closing movement of the first opening/closing body 20a and the second opening/closing body 20b is stopped, and when in the half-open/stopped state, Stopping the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is continued. After that, the opening/closing control unit 74a shifts to SD1 and repeats the processing of SD1 and SD2 until it is determined that no obstacle is detected in SD2.

In SD3, the opening/closing control section 74a determines whether the input section 71 has received an input of a closing signal, an opening signal, or a stop signal. When the opening/closing control unit 74a determines that input such as a closing signal is being accepted (SD3, Yes), the process proceeds to SD4. On the other hand, if it is determined that the input such as a closing signal is not accepted (SD3, No), the process moves to SD5.

In SD4, the opening/closing control unit 74a moves the first opening/closing body 20a and the second opening/closing body 20b to close or open based on the closing signal, opening signal, or stop signal input in SD3, or moves the first opening/closing body 20a and the second opening/closing body 20b to close or open, or The opening/closing movement of the body 20a and the second opening/closing body 20b is stopped (For example, when an input of an opening signal is received in the half-open/open movement state, the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is continued.) That is, when receiving an input of an operation signal corresponding to a moving state, the moving state is continued).

In SD5, the opening/closing control unit 74a determines whether the opening/closing state of the first opening/closing body 20a and the second opening/closing body 20b is a half-open state.

Although the method for determining whether the state is half-open is arbitrary, in the embodiment, the determination is made based on whether or not input of a fully closed state signal and a fully open state signal is received by the input unit 71, If the input of the fully closed state signal or the fully open state signal is not accepted, it is determined that the state is half open, and if the input of the fully closed state signal or the fully open state signal is accepted, it is determined that the state is not half open. do.

When it is determined that the opening/closing control section 74a is in the half-open state (SD5, Yes), the opening/closing control section 74a moves to SD1, and thereafter repeats the processing from SD1 to SD5 until it is determined in SD5 that it is not in the half-open state. On the other hand, if it is determined that it is not in the half-open state (SD5, No), the half-open state processing is ended.

With such half-open state processing, the first opening/closing body 20a and the second opening/closing body 20b can be opened and closed regardless of the detection result of the first obstacle detection unit 61 in the half-open state. Therefore, it is possible to prevent the first opening/closing body 20a and the second opening/closing body 20b from being detected as obstacles by the first obstacle detection unit 61 in the half-open state, and the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is prevented. can be prevented from being inhibited.

Through the opening/closing process as described above, the obstacle detection area of the first obstacle detection section 61 can be switched to one of a plurality of setting areas according to the opening/closing state of the first opening/closing body 20a and the second opening/closing body 20b. Therefore, it is possible to detect obstacles according to the open/closed states of the first opening/closing body 20a and the second opening/closing body 20b. Therefore, obstacles can be accurately detected according to the open/closed states of the first opening/closing body 20a and the second opening/closing body 20b without obstructing the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b. The usability of the opening/closing control system 60 can be improved.

The obstacle detection area of the first obstacle detection unit 61 can be switched to one of a plurality of setting areas depending on the open/close state of the first open/close body 20a and the second open/close body 20b. It is possible to detect obstacles such as Therefore, obstacles can be accurately detected according to the open/closed states of the first opening/closing body 20a and the second opening/closing body 20b without obstructing the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b. The usability of the opening/closing control system 60 can be improved.

Furthermore, since the fully closed setting area A1 and the fully open setting area A2 include at least an area that substantially corresponds to the locus of the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b from the fully open state to the fully closed state, Since it becomes easier to detect obstacles that may collide with the first opening/closing body 20a or the second opening/closing body 20b in the fully open state and the fully open state, it is possible to improve the accuracy of detecting obstacles in the fully closed state and the fully open state.

Further, the fully closed setting area A1 is an area that does not include the area corresponding to the first opening/closing body 20a and the second opening/closing body 20b in the fully closed state, and the fully open setting area A2 is an area that does not include the area corresponding to the first opening/closing body 20a and the second opening/closing body 20b in the fully closed state. 20a and the second opening/closing body 20b, it is possible to avoid detecting the first opening/closing body 20a and the second opening/closing body 20b as obstacles in the fully closed state and the fully open state. It is possible to prevent the opening/closing movements of the first opening/closing body 20a and the second opening/closing body 20b from being obstructed.

Further, the first obstacle detection section 61 is provided in the first opening/closing body 20a and the second opening/closing body 20b, and the fully closed setting area A1 is set with the position of the first obstacle detecting section 61 in the fully closed state as a starting point. Since the fully open setting area A2 is set using the position of the first obstacle detection unit 61 in the fully open state as the starting point, the obstacle detection area of the first obstacle detection unit 61 according to the fully closed state and the fully open state is set as the starting point. Since it is easier to set, it becomes easier to further improve the accuracy of detecting obstacles in the fully closed state and fully open state.

Further, the first opening/closing body 20a is an opening/closing body for a folding door, and the first obstacle detection unit 61 is provided on the door edge side portion of the protruding side surface of the first opening/closing body 20a. Since there is no need to separately provide the first obstacle detection section 61 on a special support means (for example, a pole, etc.) located near the opening 3, the ease of installation of the first obstacle detection section 61 can be ensured. Furthermore, compared to the case where the first opening/closing body 20a is provided at the door end side portion of the protruding side surface, it is possible to avoid difficulty in detecting obstacles in the fully open state, and it is possible to ensure accuracy in detecting obstacles.

In addition, since the opening/closing control unit 74a opens and closes the first opening/closing body 20a and the second opening/closing body 20b in the half-open state, regardless of the detection result of the first obstacle detection unit 61, the first obstacle Regardless of the detection result of the detection unit 61, the first opening/closing body 20a and the second opening/closing body 20b can be opened and closed.

(About the setting area)
In the above embodiment, it has been explained that the fully open setting area A2 and the fully closed setting area A1 are set to be different from each other, but the invention is not limited to this. For example, they may be set in the areas shown in FIG. 8.

Further, in the above embodiment, regarding the fully closed setting area A1, the length of the fully closed setting area A1 in the horizontal direction is approximately the length from the left end of the left vertical frame member 11 to the right end of the right vertical frame member 12. The lengths are the same, and the length of the fully closed setting area A1 in the front and rear direction is approximately the same as the length of the first opening and closing body 20a and the second opening and closing body 20b in the front and rear direction in the fully open state. Although it has been explained that it is set, it is not limited to this. For example, the length of the fully closed setting area A1 in the left-right direction may be set to be shorter than the length from the left end of the left vertical frame member 11 to the right end of the right vertical frame member 12. Further, the length of the fully closed setting area A1 in the front and rear direction may be set to be longer than the length of the first opening and closing body 20a (or the second opening and closing body 20b) in the front and rear direction in the fully open state.

Further, in the above embodiment, it has been explained that the fully open setting area A2 is set to be located slightly closer to the outside of the building than the opening 3, but the invention is not limited to this. For example, it may be set to include an area on the outdoor side of the building with respect to the opening 3 and an area of the opening 3 or an area on the indoor side of the building with respect to the opening 3. In addition, it was explained that the length of the fully open setting area A2 in the front and back direction is set to be approximately the same length as the length of the first opening and closing body 20a (or the second opening and closing body 20b) in the front and back direction in the fully open state. However, the length is not limited to this, and may be set to be longer than the length of the first opening/closing body 20a (or the second opening/closing body 20b) in the front-rear direction when the opening/closing body 20a is fully open, for example.

Further, in the above embodiment, it has been explained that the setting area includes the fully closed setting area A1 and the fully open setting area A2, but the setting area is not limited to this. A half-open setting area A3, which is an object detection area, may be included. In this case, the setting method of the half-open setting area A3 is arbitrary, but it is desirable to set it so as not to obstruct the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b. For example, the fully closed setting area A1 (or the fully open setting area A2). As an example, as shown in FIG. 13, the length in the longitudinal direction of the half-open setting area A3 is set to less than half the length in the left-right direction of the fully closed setting area A1 (or the fully open setting area A2), and the half-open setting area A3 The length in the lateral direction may be set to less than half the length in the front-rear direction of the fully closed setting area A1 (or fully open setting area A2). In the half-open state process, after the switching unit 74b sets the obstacle detection area of the first obstacle detection unit 61 to the half-open setting area A3 in FIG. 13, the processes from SD1 to SD5 are executed, and in SD1 Based on the detection results of the first obstacle detection section 61 and the second obstacle detection section 62, it may be determined whether an obstacle is detected.

Further, in the above embodiment, when an obstacle is detected in the fully closed setting area A1 (or fully open setting area A2), the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is stopped. Although explained above, it is not limited to this. For example, the fully closed setting area A1 or the fully open setting area A2 may be divided into a plurality of sections, and the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b may be controlled differently depending on each division. As an example, if an obstacle is detected in a region corresponding to the locus of opening/closing movement of the first opening/closing body 20a and second opening/closing body 20b in the fully closed setting area A1, the first opening/closing body 20a and the second opening/closing body 20b are The opening/closing movement of the opening/closing body 20b is stopped. On the other hand, if an obstacle is detected in an area that does not correspond to the locus of opening/closing movement of the first opening/closing body 20a and second opening/closing body 20b in the fully closed setting area A1, the first opening/closing body 20a and the second opening/closing body Although the opening/closing movement of the body 20b continues, the speed of the opening/closing movement may be reduced from the normal speed.

(About opening/closing process)
In the above embodiment, it has been explained that SD1 and SD2 are performed, but SD1 and SD2 may be omitted.

Further, in the above embodiment, it has been explained that the opening/closing movement of the first opening/closing body 20a and the second opening/closing body 20b is stopped at SB4, SC4, and SD2, but the present invention is not limited to this. For example, in addition to such processing, information indicating that an obstacle has been detected may be output by an output means (not shown) (display means or audio output means).

Therefore, obstacles can be accurately detected according to the open/closed state of the opening/closing body without interfering with the opening/closing movement of the opening/closing body, and the usability of the opening/closing control system can be improved.

According to the opening/closing control system described in Appendix 2, the fully closed setting area and the fully opening setting area include at least an area substantially corresponding to the locus of the opening/closing movement of the opening/closing body from the fully open state to the fully closed state, so that the fully closed state is Alternatively, since it becomes easier to detect obstacles that may collide with the opening/closing body in the fully open state, it is possible to improve the accuracy of detecting obstacles in the fully closed state and the fully open state.

According to the opening/closing control system described in Appendix 3, the fully closed setting area is an area that does not include the area corresponding to the opening/closing body in the fully closed state, and the fully open setting area corresponds to the opening/closing body in the fully open state. Since the area does not include any area, the opening/closing body can be prevented from being detected as an obstacle in the fully closed state and the fully open state, and the opening/closing movement of the opening/closing body can be prevented from being obstructed.

According to the opening/closing control system described in Appendix 4, the obstacle detection means is provided in the opening/closing body, the fully closed setting area is set using the position of the obstacle detecting means in the fully closed state as a starting point, and the fully open setting area is set as a starting point. Since the position of the obstacle detection means in the fully open state is set as the starting point, it is easier to set the obstacle detection area of the obstacle detection means according to the fully closed state and the fully open state. This makes it easier to further improve the accuracy of detecting obstacles.

According to the opening/closing control system described in Appendix 5, the opening/closing body is an opening/closing body for a folding door, and the obstacle detection means is provided on the door edge side portion of the protruding side surface of the opening/closing body, so that, for example, Since there is no need to separately provide the obstacle detection means on special support means (for example, a pole, etc.) located near the opening, ease of installation of the obstacle detection means can be ensured. Further, compared to the case where the opening/closing body is provided at the door end side portion of the protruding side surface, it is possible to avoid difficulty in detecting obstacles in the fully open state, and to ensure accuracy in detecting obstacles.

According to the opening/closing control system described in Appendix 6, the opening/closing control means opens and closes the opening/closing body regardless of the detection result of the obstacle detection means in the half-open state, so that the opening/closing control means opens and closes the opening/closing body regardless of the detection result of the obstacle detection means in the half-open state. Regardless of the situation, the opening/closing body can be opened and closed. Therefore, in the half-open state, the opening/closing body can be prevented from being detected as an obstacle by the obstacle detection means, and the opening/closing movement of the opening/closing body can be prevented from being obstructed.
