る給紙装置。 A power transmission gear, a partially toothed gear that is provided at a position where it can mesh with the power transmitting gear and is always biased to rotate in one direction, and a paper feeding gear that is coaxially fixed to the partially toothed gear. The recording paper path is opened and closed by a half-moon roller, an electromagnetically biased drive source, a lever that is rotated by the drive source to take two positions, and an elevating member provided on a part of the lever. and a shutter, wherein when the lever assumes the first position, unidirectional rotational biasing of the partially toothed gear is prevented, the partially toothed gear and the power transmission gear do not mesh, and the shutter is is opened and the lever assumes the second position, the partially toothed gear is urged to rotate in one direction, and as a result engages with the power transmission gear and rotates approximately once, then is prevented from rotating and the shutter is closed. A paper feeding device characterized in that it is configured to be
