    • A driving apparatus of a curtain includes a field portion disposed in a curtain rail containing a curved portion. The field portion includes a yoke and a magnet group having magnetic poles disposed along the yoke alternately so that adjacent poles are different from each other and which is preferably formed of a flexible rubber magnet. There is provided a movable portion guided on the curtain rail movably and including a core base opposed to the magnet group, a plurality of cores project from the core base toward the magnet group and are integrally formed in the core base and coils are wound on a plurality of cores. Further, a commutator which switches the polarity for the movable portion is provided to form a linear motor and thereby the polarity of a dc power source for energizing the commutator is switched so that the curtain attached, at an end thereof, to the movable portion is moved along the curtain rail in one direction and the opposite direction to open and close the curtain.
    • 帘幕的驱动装置包括设置在包含弯曲部分的帘子轨道中的场部分。 场部包括磁轭和具有沿着磁轭交替设置的磁极的磁体组,使得相邻的磁极彼此不同,并且优选地由柔性橡胶磁体形成。 提供了一种在幕轨上可移动地引导的可移动部分,并且包括与磁体组相对的芯基,多个芯从芯基部朝向磁体组突出,并且一体地形成在芯基部中,线圈缠绕在 多个核心。 此外,设置切换可动部的极性的换向器以形成线性马达,从而切换用于对换向器通电的直流电源的极性,使得在其一端附接到可动部的帘幕是 沿着一个方向沿着窗帘轨道移动,并且相反的方向打开和关闭窗帘。
