Will always be pulled tight.

On the contrary, in order to remove the torsion bar 30 attached to the wall surface, the above-described operation may be repeated.

9 is a remote drive control motor driving circuit capable of receiving a wirelessly controlled signal to change the rotation direction of the motor. First, when AC power is applied to the circuit part of the device, the signal of the reset unit 65 is applied. By this, when it is input to the reset terminal of CPU 68, it will be in an initial state.

Reference numeral 62 is a sensor input unit which receives a signal output from a remote controller (not shown) by a user's operation by the infrared sensor 66 to operate the remote control IC 67.

Reference numeral 61 denotes a main control unit, which is divided into a pulse signal input to terminal 12 of the CPU 68, i.e., reverse rotation (closed), forward rotation (open), stop (STOP), and the like.

The CPU 68, which receives any of the signals described above, outputs the address of IC2 69 for the output from terminal 32 to terminal 39, and at terminal 10 to terminal 10 of the ROM 70, _In order to designate the address number received from ₂ (69), feed back the output from the 11th terminal to the 19th terminal of ROM 70 to prevent error, and the 3rd terminal of IC ₂ (69) mentioned above. After inputting to the terminal 18, the control from the above-described internal program of the ROM 70 is sent back to the terminal 29, terminal 30 of the CPU 68.

The CPU 68, which receives the above-described data values, has a signal of "HIGH" or "LOW" as the terminal 1 to operate the motor in the open direction (forward rotation) or the close direction (reverse rotation). The output is output to the motor driver 63. When the terminal 1 and the terminal 2 of the CPU 68 are both "low" or "high" as described above, the motor stops. .

That is, when any one of two terminals 1 and 2 of the CPU 68 is "high", the motor starts to operate, and both terminals 1 and 2 of the CPU 68 are "high". When it is low or high, the motor stops.

Therefore, the opening / closing operation according to the rotation of the motor will be described in more detail. First, when the motor (not shown) is stopped, a signal in which the comparison detected signal from the CPU 68 is simultaneously applied to the first and second terminals is output. When both signals are "low" or "high", a trigger current does not flow through the gates G of the triacs TA1 and TA2, and thus the motor is in a stopped state (standby state).

In the case where the motor reverses (curtains closed) in such a state, a "high" signal is applied to the first terminal of the CPU 68 and a "low" phase signal is applied to the second terminal. On the NOT gate (NOT1) and (NOT2) output sides, the states "low" and "high" are displayed.

At this time, the phototriac PT2 is turned on by the signal of the "high" state shown at the output terminal of the NOT gate NOT2.

Therefore, a signal flows through the gate terminal G of the triac TA2, and the triac TA2 is "turned", so the curtain is closed as the motor reverses.

At this time, if the stop signal is input while the curtain is closing, the motor stops and the curtain is closed, and immediately after the vaccine is input to the motor for 2 seconds according to the instruction of the program, the motor rotates forward for 2 seconds and the transmission gear (9) is engaged with the driven gear 10, and the initial state is released.

Next, a description will be given of a case in which the motor rotates forward. The signal "low" is applied to the first terminal of the CPU 68 and the "high" state is applied to the second terminal. In this case, the NOT gate (NOT1) is applied. ). At the output of (NOT2), "high" and "low" signals are displayed respectively.

At this time, the phototriac PT1 is turned on as a "high" state signal displayed at the output terminal of the NOT gate NOT1, and a signal flows to the gate G terminal of the triac TA1. Tonon ", so the motor rotates forward to open the curtain.

At this time, as described above, when the motor stops, when the vaccine signal is input to the motor for 2 seconds according to the instruction of the program, the motor rotates backward for 2 seconds to release the engagement of the transmission gear 9 and the driven gear 10 to the initial stage. It is in a state.

In addition, (64) is a sensor unit for detecting the rotation state of the motor, the sensor that operates only when the motor is driven from the signal input from the initial remote control, or the rotation of the motor, that is, the curtain is fully opened or closed. Although not necessary during the operation of the motor, light is generated and reflected only when the motor rotation is overloaded (when the motor is rotating but the curtain is open or closed to the end). It is a sensor unit which is input to the terminal No., reads, and outputs a stop signal to terminals 1 and 2 of the CPU 68 to completely stop the rotation of the motor.

In this way, the present invention receives the radio-controlled signal to change the rotation direction of the motor, the curtain can be opened and closed automatically, and the transmission gear is installed on the rotating shaft of the motor to transmit power to the pulley, couple Anti-vibration rubber and anti-vibration rubber plate are inserted at the edge of the ring box to prevent shaking. The cable torsion bar always pulls the towing wire tightly, and it is easy to attach using a spring pusher. It can be installed vertically or horizontally in the direction of.
