Abstract
Official abstract text for this publication.
A removable device is to be detachably attached to an apparatus main body. The removable device includes a conveying drive gear attached to a first rotational shaft, an agitating drive gear attached to a second rotational shaft, and a torque transmission gear attached to a third rotational shaft. When an addendum circle diameter of the conveying drive gear is A, and an addendum circle diameter of the agitating drive gear is B, B>A is satisfied. The torque transmission gear moves around the conveying drive gear to access the agitating drive gear.
First claim
Opening claim text (preview).
The invention claimed is: 1. A removable device to be detachably attached to an apparatus main body, the removable device comprising: a conveying drive gear attached to a first rotational shaft; an agitating drive gear attached to a second rotational shaft; and a torque transmission gear attached to a third rotational shaft, wherein when an addendum circle diameter of the conveying drive gear is A, and an addendum circle diameter of the agitating drive gear is B, B>A is satisfied, and the torque transmission gear moves around the conveying drive gear to access the agitating drive gear. 2. The removable device according to claim 1 , wherein the torque transmission gear is interlocked with movement of an external shutter to approach the agitating drive gear, and wherein, after the torque transmission gear approaches the agitating drive gear, among an axis of the conveying drive gear, an axis of the agitating drive gear, and an axis of the torque transmission gear, the axis of the torque transmission gear is located at a highest position. 3. The removable device according to claim 1 , wherein, among an axis of the conveying drive gear, an axis of the agitating drive gear, and an axis of the torque transmission gear, the axis of the torque transmission gear is located at a highest position, prior to movement of an external shutter, after the movement of the external shutter, and during the movement of the external shutter. 4. The removable device according to claim 1 , wherein, when an external shutter is opened, the torque transmission gear moves toward the agitating drive gear. 5. The removable device according to claim 1 , wherein, when an external shutter is opened, a contacted part moves upward beyond an axis of the conveying drive gear. 6. The removable device according to claim 1 , wherein an external shutter and a contacted part are integrally formed. 7. The removable device according to claim 1 , wherein a contacted part extends from an external shutter, and the contacted part is formed by bending.
