Has been.

The opening / closing control of the curtain in the electric curtain device configured as described above will be described below with reference to FIGS. 7 and 8.

When the push button switch 3d, which is the operation switch 3, is pressed (step 100 in FIG. 8), the main control circuit 2a of the control block 2 turns on / off the contact connection of the detection means 6 by the signal board 9. (Step 101 in FIG. 8). If the mover 5 has already reached the detection means 6, the main control circuit 2a determines that the curtain 4 has been closed and outputs a current to the mover 5 to the power supply circuit 2b to open the curtain 4. (At time A in FIG. 7),
A current flows through the coil 5b via the power supply board 8 and the brush 5e. At this time, the direction of the current flowing through the coil 5b is
This is the direction in which the mover 5 runs away from the detection means 6 (step 102 in FIG. 8). The main control circuit 2a
If the mover 5 has not reached the detection means 6, the power supply circuit 2b outputs a current so that the mover 5 travels in the direction toward the detection means 6 (at the point B in FIG. 7). An electric current is supplied to the coil 5b via the brush 5e. At this time, the direction of the current flowing through the coil 5b is the direction in which the mover 5 travels in the direction toward the detection means 6 (step 103 in FIG. 8). The mover 5 that has started running in this way continues to run with current flowing from the power supply circuit 2b until the push button switch 3d is no longer depressed, and the main control circuit 2

Step 108), when the mover 5 reaches the detection means 6 (at a point D in FIG. 7), the current supply to the power supply circuit 2b is terminated and the traveling of the mover 5 is stopped (Step 10 in FIG. 8).
9). Next, the main control circuit 2a starts a timer count in the timer section (Step 110 in FIG. 8),
A predetermined time t1 of, for example, 5 seconds is counted from the arrival detection of the mover 5 (step 111 in FIG. 8). If the main control circuit 2a detects that the push button switch 3d is turned off before the end of the counting of the predetermined time t1, the main control circuit 2a stops the timer counting in the timer section (step 112 in FIG. 8). At this time, the movable element 5 remains at the detection means 6, the contact connection of the detection means 6 remains on, and the curtain 4 is closed. If the main control circuit 2a continues to detect the ON state of the push button switch 3d by the end of the count of the predetermined time t1, the main control circuit 2a opens the curtain 4 in the same manner as in the above-described step 102, in order to open the curtain 4. Output current to the mover 5 (at the point E in FIG. 7), the power supply substrate 8 and the brush 5e.
A current flows through the coil 5b via the. Coil 5 at this time
The direction of the current flowing through b is the direction in which the mover 5 runs away from the detection means 6.

Therefore, in the electric curtain device as described above, the detecting means 6 for notifying the control block 2 of the arrival of the mover 5 is provided at a predetermined position of the curtain rail 1, and the control block 2 If a linear motor drive instruction is continuously received from the operation switch 3 while receiving the notification that the mover 5 has arrived from the means 6, the linear motor moves in the direction opposite to the direction in which it has proceeded. Since the control is performed so as to control the opening and closing of the curtain 4 with one operation switch 3, there is no need to operate a plurality of operation switches 3, and the operation is not mistaken. Also, since the operation switch 3 may be a single switch, the operation switch 3
For example, if the exposed area from the wall surface can be reduced, or if the exposed area from the mounting surface of the operation switch 3 does not need to be reduced, the area in contact with the operation switch 3 can be increased and the operability can be improved. .

The operation switch 3 gives an instruction to drive the linear motor to the control block 2 while there is an external input. The control block 2 detects the notification that the mover 5 has arrived. 6, if there is an operation input continued for a predetermined time t1 or more following the operation switch 3 after the operation switch 3, the linear motor is controlled so as to proceed in the opposite direction to the previous traveling direction. Since the curtain 4 does not open immediately upon reaching the means 6, the operation switch 3 is used to close one end of the curtain 4.
Since there is enough time to release the hand from the, the operability can be further improved. In addition, since the curtain 4 is opened and closed by continuously operating the operation switch 3, it is not necessary to intermittently input a plurality of operation inputs to the operation switch 3 and the operation is not troublesome. The end can be stopped at any position.
