Claims

[Scope of utility model registration request]

A rotary shaft that has an annular groove on its outer periphery and rotates in appropriate conjunction with a paper feeding mechanism of a paper supply destination, and an elastic engagement portion that fits into the annular groove and rotatably fits on the outer periphery of the rotary shaft. The clutch has a substantially annular engaging member, an elastic retaining portion that engages with the engaging member, and a clutch element accommodating portion on the inner peripheral portion, and is rotatably fitted to the outer periphery of the rotating shaft. , a paper feed roller that is engaged with an engaging member in an elastic retaining portion and rotates integrally with the engaging portion; and a paper feeding roller that is housed in the clutch element housing portion and that rotates only when the rotating shaft rotates in one direction. A paper feed roller attachment mechanism for a paper feeding device, characterized by comprising a clutch element for transmitting information to the paper feed roller.
