As shown in FIG. The wheels 41 can be inserted into the grooves 111 of the curtain rail 100 by determining the orientation of the runners 40 so that the rotation axes of the wheels 41 are aligned with the grooves 111 of the curtain rail 100 . The wheels 41 can be attached to the curtain rail 100 by rotating the runner 40 so that the rotation axis of the wheels 41 is perpendicular to the longitudinal direction of the curtain rail 100 .

Next, the other runner 40 attached to the curtain rail 100 is attached to the device main body 10 . Thereby, as shown in FIG. 13 , the curtain opening/closing device 1 is attached to the curtain rail 100 via the pair of runners 40 . When the user presses the push button 14 in the state shown in FIG. 12, the push button 14 moves upward along the guide groove 11a, and as described above, pushes a portion of the tire 30 from the upper surface of the apparatus main body 10. can be protruded. Thereby, as shown in FIG. 13 , the tire 30 can be brought into close contact with the lower surface 110 of the curtain rail 100 .

By attaching the cover 20 to the apparatus body 10 in the state shown in FIG. 13, the state shown in FIG. 14 is obtained. This completes the attachment of the curtain opening/closing device 1 to the curtain rail 100 .

In the state shown in FIG. 14, the curtain rail 100 is sandwiched between the wheel 41 of the runner 40 and the tire 30.

Since a curtain (not shown) is attached to the curtain rail 100 , the curtain can be opened and closed by moving the curtain opening/closing device 1 along the curtain rail 100 .

When cover 20 receives an external force in the direction of arrow D1 shown in FIG. When the operation switch 16 is actuated, the controller of the circuit board 50 drives the motor 61 to rotate the tire 30 in the direction of arrow R1 in FIG. Thereby, the curtain opening/closing device 1 can be moved along the curtain rail 100 in the direction of the arrow D1. That is, the curtain opening/closing device 1 can be moved in the same direction as the direction of the external force applied to the cover 20 (direction of arrow D1).

On the other hand, when cover 20 receives an external force in the direction of arrow D2 shown in FIG. When the operation switch 16 is actuated, the controller of the circuit board 50 drives the motor 61 to rotate the tire 30 in the direction of arrow R2 in FIG. Thereby, the curtain opening/closing device 1 can be moved along the curtain rail 100 in the direction of the arrow D2. That is, the curtain opening/closing device 1 can be moved in the same direction as the direction of the external force applied to the cover 20 (direction of arrow D2).

When the curtain opening/closing device 1 is moved as described above, if a force acts on the curtain opening/closing device 1 in a direction opposite to the moving direction of the curtain opening/closing device 1, an excessive load may be applied to the drive of the motor 61. In this case, the control unit can stop driving the motor 61, and can suppress excessive power consumption associated with driving the motor 61 when overloaded. Here, whether or not an excessive load is applied to drive the motor 61 can be determined based on the power supplied to the motor 61 .

According to this embodiment, as shown in FIG. 14, the curtain opening/closing device 1 can be moved along the curtain rail 100 simply by displacing the cover 20 in the direction of the arrow D1 or the direction of the arrow D2. Here, since the cover 20 covers the apparatus main body 10, the curtain opening/closing apparatus 1 can be moved simply by applying an external force in the directions of the arrows D1 and D2 to an arbitrary portion of the cover 20. FIG. As a method of applying an external force in the directions of arrows D1 and D2 to the cover 20, for example, the user can directly press an arbitrary portion of the cover 20, or the user can pull the curtain to apply the force through the curtain (not shown). can also be used to push the cover 20.

As described above, in order to move the curtain opening/closing device 1, the operation switch 16 must be pressed. The curtain opening/closing device 1 can be moved more easily than when the switch 16 is pressed directly. Moreover, by covering the device main body 10 with the cover 20, the appearance of the curtain opening/closing device 1 can be simplified.

It is displaced (rotated) from the indicated position to the position indicated by the dotted line in FIG. As a result, as described above, the projection 23a of the cover 20 pushes the operation switch 16, thereby moving the curtain opening/closing device 1 in the direction of the arrow D1.

When the curtain is moved while moving the curtain opening/closing device 1 in the direction of the arrow D1, the upper end portion of the curtain opening/closing device 1 is provided with a moving direction (the direction of the arrow D1) of the curtain opening/closing device 1 by a curtain runner or the like. A reaction force in the opposite direction may act. Here, since the position where the reaction force acts on the curtain opening/closing device 1 is above the position P of the support pin 15, the reaction force moves the cover 20 from the position indicated by the solid line in FIG. 15 to the position indicated by the dotted line in FIG. It may be displaced (rotated) in position.

In this case, the projecting portion 23b of the cover 20 does not push the operation switch 16 due to the reaction force, and the curtain opening/closing device 1 moves in the direction opposite to the original moving direction (the direction of the arrow D1 shown in FIG. 15). can be prevented. When the user moves the curtain opening/closing device 1, an external force is applied to the cover 20 at a position below the position P of the support pin 15, so that the curtain opening/closing device 1 can be moved in a desired direction. can be made
