<P>PROBLEM TO BE SOLVED: To provide a device for controlling the opening/closing position of a curtain for greenhouse or the like which has the following mechanism: transmitting rotation of a curtain driving shaft to an intermediate measuring shaft through a speed reduction mechanism, also transmitting the rotation of the intermediate measuring shaft to a final measuring shaft through another speed reduction mechanism and integrating curtain stopping switches set at the intermediate measuring shaft and the final measuring shaft into the power source circuit to stop power supply so as to precisely stop the greenhouse curtain or the like at the set opening position or the set closing position. ??<P>SOLUTION: The device for controlling the opening/closing position of a curtain for a greenhouse or the like has the following structure: a large shaft part 80 is set up at a measuring shaft comprising the intermediate measuring shaft 45 or the final measuring shaft 49; cum members 56 and 57, or 66 and 67 having cam parts 58 and 59, or 68 and 69 are engaged with the large shaft part 80 to be fixedly positioned; and the cam parts of the cam members actuate micro switches 61 and 63, or 71 and 73 for the curtain stopping switch. ??<P>COPYRIGHT: (C)2010,JPO&INPIT ??
