  • Patent number: 4615630
    Abstract: An impact printer having a roll platen on which a continuous paper is set and fed by the rotation of the roll platen rotated by a first motor, and a cut sheet is fed on the continuous paper by a feeding mechanism which includes feed rollers rotated by a second motor. When information is printed on the cut sheet, a controller drives a second motor and a first motor so as to feed the cut sheet and the continuous paper in the same direction. Since the continuous paper is fed synchronously when feeding the cut sheet during printing on the cut sheet, print elements impact on different positions of the continuous paper and the roll platen. Accordingly, impact traces on specific areas of the continuous forms and wearing of specific areas of the platen are prevented.
