The free end of the roller raising lever on the paper feed roller shaft side is brought into contact with the cam surface of the second cam pivotally mounted on the machine frame side, and the small diameter portion of the cam surface is attached to the roller raising lever by the return spring. A rotational force is applied to the second cam in the direction of bringing the cam surfaces into contact with each other, and a gap is provided between both large and small diameter portions of the cam surface of the second cam and both rotational ends of the lifting lever, and the large diameter portion of the cam surface By setting the spring force so that the rotation of the second cam is restricted when it comes into contact with the paper lifter lever, the paper feed roller can move without being hindered by the second cam during paper feeding. Since the paper is sent out by moving up and down, the original function of the paper feeding device is maintained, and the paper feeding roller can be raised and stopped at that position by operating the handle, improving operability. Furthermore, when the machine is restarted with the paper feed roller raised, the return spring automatically lowers the paper feed roller and brings it into pressure contact with the paper feed roller, preventing incorrect paper from coming out and reducing the amount of paper waste. decreases.
