上げている。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
As shown in the figure, a control unit having a low component height is mounted on the boards 3 and 4, and a power unit composed of a large component is mounted on the board 5. Substrates 3-5
It has a U-shaped configuration. Then, as shown in FIG. 2, the lower end surfaces of the substrates 3 and 5 contact the inner surface of the case 7 and are fixed to the case 7 side. By abutting the end faces of the substrates 3 to 5 in this manner, useless space in the circuit of the electric curtain drive device is eliminated and the component mounting density per volume is increased.
ところで、制御部側の基板3,4の端部には切欠部8,9を形
