Claims (1)

[Scope of Claim for Utility Model Registration] A pair of copy paper ejection rollers disposed in the traveling direction of copied copy paper, and a pair of copy paper ejection rollers disposed downstream of the paper ejection roller pair with respect to the traveling direction, a first storage section that stores the copy paper discharged from the pair of rollers; and a first storage section provided near the downstream side of the pair of paper discharge rollers that guides the copy paper discharged from the pair of paper discharge rollers to the first storage section. a copy paper path switching member placed at a first position; a copy paper length detection device that detects the length of the copy paper until the leading edge of the copy paper reaches a pair of paper ejection rollers; The paper length detection device is energized when copy paper of a different size from the copy paper is detected, and moves the copy paper path switching member from the first position to move the copy paper to the first storage section. a solenoid for switching to a second position for guiding the copy paper in the reversing direction; a second storage section disposed in the reversing direction and storing the reversely guided copy paper; and a second storage section for discharging the copy paper only from the first storage section. A manual release switch for selectively disabling excitation of the solenoid in order to store the paper.
