Patent ID: 8270883

Claim:
A powder carrying apparatus comprising: a driving gear to which the drive is carried from a drive source capable of rotating positive and negative; a rocking gear capable of rotating around a rolling shaft which is movably supported along a rocking guide portion installed in a frame, wherein the rocking gear is engaged with the driving gear, when the drive source rotates positive, the rocking gear is moved to a prescribed first rocking position along the rocking guide portion, and when the drive source rotates negative, the rocking gear is moved to a second rocking position different from the first rocking position along the rocking guide portion; a first intermediate transmission system having at least one or more gears including a first intermediate gear engaged with the rocking gear that has been moved to the first rocking position; a first powder carrying member to which the rotation is carried from the first intermediate transmission system to carrying the powder; a first regulating gear capable of rotating around a first regulating shaft which is movably supported along a first regulating guide portion installed in the frame, wherein when the drive source rotates positive, the first regulating gear is moved to a first release position separated from the first fixing teeth installed in the frame, and when a force in a direction in which the drive source rotates negative acts on the first powder carrying member, the first regulating gear is moved to a first regulating position in which the first regulating gear is engaged with the first fixing teeth to regulate the rotation of the first intermediate gear; a second intermediate transmission system having at least one or more gears including a second intermediate gear engaged with the rocking gear that has been moved to the second rocking position; a second powder carrying member to which the rotation is carried from the second intermediate transmission system to carry the powder; and a second regulating gear capable of rotating around a second regulating shaft which is movably supported along a second regulating guide portion installed in the frame, wherein when the drive source rotates negative, the second regulating gear is moved to a second release position separated from the second fixing teeth installed in the frame, and when a force in a direction in which the drive source rotates positive acts on the second powder carrying member, the second regulating gear is moved to a second regulating position in which the second regulating gear is engaged with the second fixing teeth to regulate the rotation of the second intermediate gear.
