ABSTRACT:
A recording apparatus of the type using a roll of recording paper in which recording paper unrolled from the roll is cut by a rotary cutter after completion of a recording operation and thereby a section of recording paper on which recording has been effected is cut from the roll is discharged into a tray. The apparatus includes at least one transporting roller before the cutter. The cutter also includes a rotary blade and a stationary blade. The recording apparatus further comprises guide plates which include an upper guide plate and lower guide plate, in order to guide the recording paper to the cutter. The upper guide plate corresponds to the rotary blade and the lower guide plate corresponds to the stationary blade. The cutter and the guide plates are arranged so as to leave a gap between a shearing edge of the stationary blade and a guiding surface of the lower guide plate. When recorded paper is discharged into the tray, there may be a bend in the recording paper that could cause a rearmost end of the cut recording paper to enter into the cutter. However, even if the rearmost end does enter into the cutter and remains on the stationary blade, a foremost end of the next section of recording paper to be cut is transported above the rearmost end due to the gap. Therefore, the likelihood of interference between the recording paper and recording paper that has been cut is greatly reduced.
