  Further, connection cords 14a to 14c are extended from the motor unit 7b, and connectors 15a to 15c are connected to tips of the connection cords 14a to 14c, respectively. The connection cord 14a is connected to the controller 16 which will be described later, the connection cord 14b is connected to the remote control light receiving section, and the connection cord 14c is attached to the hanger rail 1 in the vicinity of the motor unit 7b.

  As shown in FIG. 5, a controller 16 and a power supply unit 17 are disposed in the housing portion 1 c of the hanger rail 1. The power supply unit 17 supplies DC power to the controller 16, the tilt motor 8 and the transfer motor 13.

  As shown in FIG. 1, a pressing piece 18 protruding upward in a mountain shape is attached to the top of the top runner 2a. At one end of the hanger rail 1, that is, in the vicinity of the motor unit 7a, a first limit switch 19 is attached to the housing portion 1b, and a detector 19a of the first limit switch 19 is disposed in the rail portion 1a. It protrudes to the movement locus of the pressing piece 18.

Accordingly, when the leading runner 2a moves to one end of the hanger rail 1, the detector 19a of the first limit switch 19 is pressed upward.

Therefore, when the leading runner 2a moves to the other end of the hanger rail 1, the detector 20a of the second limit switch 20 is pressed upward.
Next, the electrical configuration of the electric vertical blind control device will be described with reference to FIG. The controller 16 includes a switch command signal input / output unit 21, a microcomputer (control unit, processing means) 22, a remote control signal input circuit 24, and a motor drive circuit 25.

  The switch command signal input / output unit 21 mediates communication between the microcomputer 22 and the operation switch (operation means) 23, and outputs an operation signal output from the operation switch 23 to the microcomputer 22.

The remote control signal input circuit 24 receives the infrared signal output from the remote control (operation means) 26 by the light receiving unit and outputs the received signal to the microcomputer 22.
The microcomputer 22 operates based on a preset processing program. The microcomputer 22 receives the pressing signals (detection signals) of the first and second limit switches 19 and 20. A motor drive circuit 25 is connected to the microcomputer 22, and the motor drive circuit 25 drives the tilt motor 8 and the transfer motor 13 forward and backward based on a control signal output from the microcomputer 22.

  Further, a dip switch (setting means) 27 is connected to the microcomputer 22. The dip switch 27 is a switch for selecting whether to operate the microcomputer 22 as a right-handed specification or a left-handed specification, and a setting signal thereof is output to the microcomputer 22. The dip switch 27 is exposed on the lower surface of the housing portion 1c of the hanger rail 1 and can be operated from the outside of the hanger rail 1.

  The microcomputer 22 switches the control based on the pressing signals of the first and second limit switches 19 and 20 by the switching operation of the dip switch 27. Note that the microcomputer 22 is set to recognize the right fit specification when the DIP switch 27 is in the on state and to recognize the left fit specification when the dip switch 27 is in the off state.

  FIG. 1 shows the case of the right fit specification, but when the vertical blind is set to the left fit specification, the pressing piece 18 is attached with the runner closest to the motor unit 7b as the leading runner 2b. Further, it is necessary to configure the leading runner 2 to move in the reverse direction by rotating the transfer motor 13 in the same direction with the spiral groove of the slat transfer shaft 5 as the reverse direction.

Next, the operation of the control device configured as described above will be described with reference to FIGS.
When power is supplied to the controller 16 (step 1), the microcomputer 22 determines whether or not the dip switch 27 is on (step 2). Here, if the DIP switch 27 is in the ON state, the microcomputer 22 recognizes that the specification is right-handed.

  Next, the microcomputer 22 determines whether one of the first and second limit switches 19 and 20 is pressed (step 3), and determines that the second limit switch 20 is pressed (step 3). Steps 4, 5) and Step 6 are performed. At this time, the vertical blind is in a state of being folded rightward as shown in FIG.

  Next, in step 6, it is determined whether or not an operation command signal is input from the operation switch 23 or the remote control 26, and if the movement of the slat 4 in the folding direction (OPEN) is commanded (step 7), it is more. Therefore, the transfer motor 13 is not operated, and the process returns to step 6.

  Further, when the transfer of the slat 4 in the pull-out direction (CLOSE) is commanded (step 8), the transfer motor 13 is operated in the slat pull-out direction, and the leading runner 2a is moved to one end side of the hanger rail 1, that is, the motor unit. The slats 4 are moved in the pulling direction by moving to the 7a side (step 9).

  When the operation command in the pull-out direction is stopped and the operation in step 9 is completed, the process proceeds to step 3. Further, when the leading runner 2a presses the first limit switch 19 during the operation of step 9, as shown in FIG. 7, since the slats 4 are all pulled out, the microcomputer 22 operates the transfer motor 13. Stop and go to step 3.

  In step 5, if the first limit switch 19 is pressed, the process proceeds to step 10 to determine whether or not an operation command signal is input. When the transfer in the slat folding direction is instructed, the transfer motor 13 is operated in the slat folding direction (steps 11 and 12), and the process returns to step 3.

  In step 10, if an operation command signal in the slat pulling direction is input, no more slats can be pulled out, so the process returns from steps 11 and 13 to step 10.

  If an operation command signal for rotating the slat in step 10 to adjust the angle is input, the process proceeds to step 15 through steps 11 to 14, the tilt motor 8 is operated, and the slat 4 is rotated. Thereafter, the process returns to step 3.

  When the first and second limit switches 19 and 20 are not pressed in step 4, that is, when the leading runner 2a is positioned between the first and second limit switches 19 and 20, Transition. In this state, the slat 4 can be folded and pulled out and the angle can be adjusted.

When an operation command signal in the slat folding direction is input, the transfer motor 13 is operated in the slat folding direction to fold the slat 4 (steps 17 and 18).
When an operation command signal in the slat pulling direction is input, the transfer motor 13 is operated in the slat pulling direction to pull out the slat 4 (steps 19 and 20).

  When an operation command signal for adjusting the angle of the slat is inputted, the tilt motor 8 is operated to rotate the slat 4 (steps 21 and 22). And after each operation | movement is complete | finished, it returns to step 3.

  In step 2, if the dip switch 27 is in the OFF state, the microcomputer 22 recognizes the left fit specification and proceeds to step 23. Next, the microcomputer 22 determines whether one of the first and second limit switches 19 and 20 is pressed (step 23), and determines that the second limit switch 20 is pressed (step 23). Steps 24 and 25) and Step 26 are entered. At this time, the vertical blind is in a state where all the slats 4 are pulled out and the second limit switch 20 is pressed by the leading runner 2b as shown in FIG.

  Next, in step 26, it is determined whether or not an operation command signal is input, and when the movement of the slat 4 in the folding direction is commanded (step 27), the transfer motor 13 is operated in the slat folding direction. The leading runner 2b is moved to one end side of the hanger rail 1, that is, the motor unit 7a side. Then, as shown in FIG. 9, each slat 4 is moved in the convolution direction (step 28).

  If the transfer of the slat 4 in the pull-out direction is instructed (step 29), no further pull-out is possible, so the transfer motor 13 is not operated and the process returns to step 26.

When the operation command in the convolution direction is stopped and the operation in step 28 is finished, the process proceeds to step 3.
In step 25, when the first limit switch 19 is pressed, the process proceeds to step 30 to determine whether or not an operation command signal is input. When the transfer in the slat convolution direction is instructed, no further slat convolution can be performed, and the process returns from step 31 to step 30.

  When an operation command signal in the slat pulling direction is input in step 30, the transfer motor 13 is operated in the slat pulling direction (steps 32 and 33), and the process returns to step 3.

  If an operation command signal for adjusting the angle by rotating the slat in step 30 is input, the process proceeds to step 35 through steps 31 to 33, the tilt motor 8 is operated to rotate the slat 4, Thereafter, the process returns to step 3.

  In step 24, when neither of the first and second limit switches 19, 20 is pressed, that is, when the leading runner 2b is located between the first and second limit switches 19, 20, the slat 4 Since any of convolution, drawer, and angle adjustment is possible, the process proceeds to step 16 and the same processing as in steps 16 to 22 is performed.

In the control device for an electric blind configured as described above, the following operational effects can be obtained.
(1) When the right limit specification is set by the dip switch 27, when the first limit switch 19 is pressed, that is, when all the slats 4 are pulled out, the pulling operation of the slats 4 is stopped and the slats 4 The folding operation of the slats is allowed, and the rotating operation of the slats 4 is allowed. Further, when the second limit switch 20 is pressed, that is, when all the slats 4 are folded, the folding operation and the pivoting operation of the slats 4 are stopped, and the pulling operation of the slats 4 is allowed.

  On the other hand, when the dip switch 27 is set as a left-fitting specification, when the first limit switch 19 is pressed, that is, when all the slats 4 are folded, the slat 4 is allowed to be pulled out, and the slat 4 The folding operation and the rotating operation are stopped. When the second limit switch 20 is pressed, that is, when all the slats 4 are pulled out, the pulling-out operation of the slats 4 is stopped, and the folding operation and the rotating operation of the slats 4 are allowed.

Therefore, based on the setting of the dip switch 27 and the program stored in the microcomputer 22, the right fit specification can be obtained without changing the connection between the first and second limit switches 19, 20 and the microcomputer 22 and the connection of the motor. It is possible to switch between left-handed specifications.
(2) The motor units 7a and 7b can be used in common for the right fit specification and the left fit specification.
