PURPOSE:To flexibly carry out addition of a new shutter device or changing of the mounting position of a controller while the burden upon wiring is reduced in a motor-driven shutter device including a plurality of shutters connected in series on one and the same transmission path. CONSTITUTION:A plurality of blind devices are successively connected by wiring 6. In the case of addition of a blind device due to a function in which each of the blind devices can transmit signals in both direction to the upstream and downstream parts, it is sufficient to connect a blind device 33 or 11 through the intermediary of the wiring 6. Further, since controllers 1 to 3 are not attached to the wiring 6 but to control parts of the respective blind devices, the mounting position of a controller may be changed with no wiring work. |
