DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic structure is the same as the conventional structure shown in FIG. 4, and an operation terminal 32 and a control terminal 33 are provided.
Are connected to the main control unit 31 via a two-wire type signal line LN, and a transmission terminal Vs sent from the main control unit 31 to the signal line LN causes a terminal 32 for operation and a terminal 33 for control. The data is transmitted by a time division multiplex transmission method between the two.
The control terminal 33 is a motor M for opening / closing the blind BL as an opening / closing body for opening / closing the opening of the building.
To control.

As shown in FIG. 2, the operation terminal 32 has a signal processing unit 11 which includes a microprocessor and is connected to the signal line LN via the transmission / reception unit 12. A storage unit 13 is connected to the signal processing unit 11, and address data is stored in the storage unit 13. When the signal processing unit 11 receives the transmission signal Vs via the transmission / reception unit 12, the address data stored in the storage unit 13 is transferred to the transmission signal Vs.
The control data of the transmission signal Vs is received when the two match with the address data of s. The operation terminal 32 includes four switches S _{1 to} S ₄
Equipped with. That is, the open switch S ₁ that specifies the rotation direction of the motor M to open the blind BL and the stop switch S ₂ that specifies to stop the rotating motor M.
And a closing switch S ₃ for designating the rotation direction of the motor M so as to close the blind BL, and a speed switch S ₄ for designating the rotation speed of the motor M. The rotation speed of the motor M can be set in 6 steps by the speed switch S ₄ , and the set rotation speed is displayed on the speed display unit 14a in which six light emitting diodes (for example, red) are arranged in a line. The operation terminal 32 includes an open / close display unit 14b that constitutes the display unit 14 together with the speed display unit 14a.
4b includes a light emitting diode (for example, green) that lights when the blind BL is completely closed, and a light emitting diode (for example, red) that lights when the blind BL is not completely closed.

On the other hand, as shown in FIG. 3, the control terminal 33 is provided with a microprocessor, which is connected to the signal line LN via the transmitter / receiver 22 and a memory in which address data is stored. And a section 23. When the transmission signal Vs including the control data corresponding to the operation data generated in the operation terminal 32 is transmitted from the main control device 31, the signal processing unit 21 causes the forward / reverse switching unit 24 or the speed control unit 25 to operate. The motor M is controlled through. Forward / reverse switching unit 2
4 operates in response to the operation of the open switch S ₁ , the stop switch S ₂ , and the close switch S ₃ , and rotates the motor M in one direction so as to open the blind BL when the open switch S ₁ is operated, When the closing switch S ₃ is operated, the motor M is rotated in the reverse direction so as to close the blind BL, and when the stop switch S ₂ is operated, the motor M is rotated.
The rotation of the blind BL is stopped to stop the blind BL at that position. The speed control unit 25 changes the rotation speed of the motor M by operating the speed switch S ₄ . The motor M is a stepping motor, and the speed control unit 25 adjusts the width of the pulse given to the motor M so as to correspond to the speed designated by the speed switch S ₄ . Full-closed data from the limit switch LS as a full-closed detection unit that detects that the blind BL is completely closed is also input to the control terminal 33. That is, the limit switch LS detects that the blind BL is closed without a gap, and the fully closed data is transmitted as operation data as in the case where the switches S _{1 to} S ₄ are operated by the operation terminal 32. It is transmitted to the main control device 31 in synchronization with the signal Vs, and is transmitted as control data to the corresponding operation terminal 32. In the operation terminal 32 that has received the control data corresponding to the fully closed data, the open / close display unit 14b
One of the two light emitting diodes is turned on to indicate that the blind BL is completely closed.

With the configuration described above, the operation terminal device 3
In FIG. 2, when the open switch S ₁ or the close switch S ₃ is operated to rotate the motor M, the blind BL is opened and closed. The rotation speed of the motor M at the time when the blind BL starts opening and closing is fixed, and the motor BL rotates at the minimum speed that can be set by the speed switch S ₄ . Here, each time the speed switch S ₄ is operated once, the rotation speed of the motor M is increased by one step, and the blind BL can be opened and closed at a desired opening / closing speed. Speed switch S ₄
When the maximum speed and the minimum speed of the rotation speed of the motor M are set, it is desirable that the direction of speed change be reversed in the next operation. That is, when the rotation speed of the motor M is the highest, the speed is decreased by one step from the next operation, and when the rotation speed of the motor M is the lowest, the speed is increased by one step from the next operation. So that Also, since there is only one speed switch S _{4, the} speed is set to the lowest speed first, and the speed is gradually increased each time the speed switch S ₄ is operated once. It is also possible to provide a pair of two switches, that is, a switch designated to the above and a switch designated to slow down the speed so that the rotation speed of the motor M can be arbitrarily adjusted. The rotation speed of the motor M thus set is displayed on the speed display unit 14a.

When it is desired to stop the blind BL at a desired position, the stop switch S ₃ may be operated. When the blind BL is completely closed, the light emitting diode of the open / close display section 14b is turned on in response to the output of the limit switch LS. To do. Further, the limit switch LS is a blind B.
It may be provided so as to detect the fully open state and the fully closed state of L respectively, and it is desirable to automatically stop the motor M when either state is detected by the limit switch LS.

In the above configuration, the limit switch LS is used to detect that the blind BL is completely closed. However, other means such as an optical sensor may be used as the full-closed detection section. Further, not only the opening / closing of the blind BL but also the opening / closing angle of the slat provided on the blind BL may be controlled, and the opening / closing body may be a curtain, a shutter, a shutter, a window or the like in addition to the blind BL. Further, the technical idea of the present invention can be applied to any device other than the opening / closing body as long as the device remotely controls the motor M.
