粉体供给装置和图像形成装置
摘要：
本发明提供一种粉体供给装置和图像形成装置。所述粉体供给装置包括：第一和第二储存部，储存粉体；第一和第二搅拌部，分别配置在所述第一和第二储存部内部；驱动部，产生正向的转动力和逆向的转动力以把驱动力赋予所述第一和第二搅拌部；第一和第二传动轴，把所述驱动力传递给所述第一和第二搅拌部；以及传递切换部，把所述驱动部的所述正向的转动力所产生的所述驱动力传递给所述第一传动轴，把所述驱动部的所述逆向的转动力所产生的所述驱动力传递给所述第一传动轴和所述第二传动轴。由此，使与要使用的粉体对应的搅拌叶片转动，防止对粉体进行不必要的搅拌。
摘要（英）：

A powder supply device includes: first and second storage sections that store powder, first and second stirring sections arranged inside the first and second storage sections, a drive section that produces a forward direction rotational force and a reverse direction rotational force to apply a drive force to the first and second stirring sections, first and second transmission shafts that transmit the drive force to the first and second stirring sections, and a transmission switching section that transmits the drive force produced by the forward direction rotational force of the drive sectionto the first transmission shaft, and that transmits the drive force produced by the reverse direction rotational force of the drive section to the first transmission shaft and the second transmissionshaft.
