Abstract
PURPOSE:To accomplish the detection of the level of powder in response to electric signals with the use of a simple and small device by generating output signals in accordance with the angle or velocity of rotations of a stirring rod, which is determined by the quantity of the powder. CONSTITUTION:A stirring rod 4, which is made rotatable about a shaft 3, is inserted into a powder box 1, in which toners for use in a copier for zerog-aphy are accommodated. The shaft 3 is driven by a motor 5 through drive gears 6 and 7, and the variation in the driving force is taken out as the variation in stress in the form of electric signals by means of strain gauge 8. Thus, the level of the toners 2 can be detected in accordance with the duration of the output signals from the strain gauge 8, which have relation with the angle of rotations of the stirring rod 4 in the toners 2.
