SOLUTION: In the flexible pole, an elevating/lowering cylinder is housed to elevate/lower in a fixed cylinder that is erected, and the elevating/lowering instrument that rotates and faces upward/downward by a servo motor is mounted on an upper end of the elevating/lowering cylinder. A battery is mounted on the elevating/lowering cylinder, and the elevating/lowering instrument is placed on the battery. COPYRIGHT: (C)2011,JPO&INPIT |
