PURPOSE:To cool the inside of a box body, to reduce the cost of a product largely, to lower extremely noises during cooling operation and to minimize power consumption by turning a windmill through a gear and a shaft by receiving the driving force of a driving source loaded on an electronic device. CONSTITUTION:When printing operation is started, a shaft 17 is rotated by a carrier motor 21, and a belt 18 begins to be moved in the direction of the arrow A of a solid line. Since the belt 18 and a carriage 19 are coupled mutually, the carriage 19 is begins to be naturally shifted in the same direction as the belt 18. When a recording device starts printing, a gear 4 is turned. Since a gear 9 is directly coupled with the gear 4, the gear 9 is revolved naturally in the direction A. Consequently, an arm 16 is energized by the revolution of the gear 9 and moved in the direction A, thus fitting a planet gear 10 to a gear 14. Since a gear 6a is integrally molded with a shaft 6, revolving torque is transmitted over a shaft 7 from the shaft 6, and lastly a windmill 1 is rotated in the direction of a solid line. |
