装置のクラツチ機構。[Scope of claim for utility model registration] (1) A drive motor for feeding or ejecting paper;
A sun gear that can rotate forward and backward in response to the driving force of the drive motor, meshes with the gear part of the sun gear, rotates at a predetermined angle by changing the rotation direction of the sun gear, and drives the gear on the paper feed side or the gear on the paper discharge side. In the clutch mechanism of an automatic paper feeder, the clutch mechanism of an automatic paper feeder includes a planetary gear that switches transmission, a paper feed roller that receives driving force from a gear on the paper feed side, and a paper discharge roller that receives drive force from a gear on the paper discharge side. The gear is composed of a gear part and a flange integral with the gear part, the transmission gear for transmitting the driving force and the planetary gear mesh with the gear part, and one of the gear shafts of the planetary gear is attached to the end face of the flange. It is characterized by forming an annular recessed groove that slidably supports the side, and also having a holding means that acts only when switching the drive transmission of the planetary gear and holds the planetary gear integrally with the sun gear. Clutch mechanism of automatic paper feeder. (2) The sun gear is integrally constituted by a small gear portion and a large gear portion, and a planetary gear is meshed with the small gear portion, and a transmission gear for transmitting the driving force is meshed with the large gear portion. A clutch mechanism for an automatic paper feeder according to claim 1.
