Claims

[Scope of utility model registration request]

(1) A feed roller that is rotationally driven in a predetermined direction and conveys the paper, a separation opening nib that cooperates with the feed roller to nip and convey the paper, and a separation roller that is rotated in the opposite direction to the paper conveyance direction (this rotation is driven A torque limiter for a paper feeding device equipped with a drive shaft, which connects the drive shaft and separation roller to apply a constant torque to the separation roller, and separates the separation roller when a load greater than the torque is applied to the separation roller. A torque limiter in which the roller is rotatable independently of the drive shaft, characterized in that the constant torque applied to the separation roller is adjustable.

(2) The torque limiter is provided between the separation roller and the drive shaft and has a latch spring that is fixed to one of them and is slidable from the other, and by changing the effective number of turns on the sliding side of the clutch spring. Utility model registration claim 1 characterized by adjusting torque
Torque limiter as described in section.

(3) A fixing screw member that is fixed on the drive shaft and has a screw on its outer periphery extending in the axial direction of the axis of the drive shaft, and a screw that engages with the screw of the fixing screw member, and by tightening or loosening the screw. The clutch spring has a hub that is movable on the fixed screw member in the axial direction and engages with the sliding side of the clutch spring, and the effective number of turns of the clutch spring is changed by moving the hub in the axial direction. Scope of claim for utility model registration No. 2
Torque limiter as described in section.
