Claims

[Scope of utility model registration request]

(1) The first for the paper feed roller that contacts the surface of the copy paper.
The rotating shaft is connected to the second rotating shaft via a power transmission means, and a one-way clutch is interposed between the paper feeding roller and the first rotating shaft to transmit power from the first rotating shaft to the paper feeding roller, or One way of transmitting power from the power transmission means to the first rotation shaft between the first rotation shaft and the power transmission means;
A latch is interposed, and power is transmitted from the power source to the second rotating shaft via a spring clutch, and the spring clutch is connected to an input shaft that surrounds the second rotating shaft and is rotated by the power source, and to the second rotating shaft. a boss provided integrally with the shaft; a coil spring wrapped around the input shaft and the boss and having one end fixed to the boss; and a coil spring surrounding the coil spring and having the other end fixed. The coil spring includes a mold wheel and a pawl that can be connected to and detached from the mold wheel, the coil spring has a winding direction that tightens the input shaft and the boss in the rotational direction of the input shaft, and the pawl tightens the mold wheel in the rotational direction of the input shaft. 1. A copy paper feeding device, wherein the power transmission means connects the first and second rotary shafts by making the second rotary shaft reciprocatingly angularly displaceable by a predetermined angle.

(2) The power transmission means includes a power transmission pin fixed to one of the first and second rotating shafts and extending perpendicularly to the axis thereof, and connected to the other of the first and second rotating shafts. and a rotating member in which a power transmission recess is formed that fits into a power transmission pin and allows relative angular displacement with the power transmission pin. Copy paper feeding device as described in Section 1.

(3) The power transmission means includes a rotating member connected to either one of the first and second rotating shafts, and a power transmitting pin fixed to the rotating member and extending perpendicularly to its axis. An insertion hole through which the power transmission pin is inserted is formed perpendicularly to the axis on the other of the first and second rotating shafts, allowing for relative angular displacement of the power transmission pin with the other one. A copy paper feeding device according to claim 1 of the claimed utility model registration.
