  • Patent number: 5154521
    Abstract: In a printer having a platen, a print head disposed opposite to the platen, and a ribbon mask fixedly provided on the print head and having a masking plate provided with an aperture to expose only the front end of the print head to the platen, an ink ribbon is extended through a space between the platen and the print head, and the masking plate is disposed between the platen and the ink ribbon to shield a recording sheet wound round the platen from the ink ribbon. The aperture of the masking plate has inclined edges inclined to a direction perpendicular to the direction of movement of the print head so as to intersect a platen center obliquely. In case the side edge of a floating portion of the recording sheet is caught in the aperture of the masking plate while the print head is moved, the side edge slides along the inclined edge to escape from the aperture, so that the side edge is not caught in the aperture of the masking plate.

  • Patent number: 5155427
    Abstract: A drive controller of the N-phase stepping motor includes a signal generator for generating M pulse signals at such an interval that the stepping motor can be driven in response to the pulse signals so as to rotate the stepping motor through an M step angle in one direction, and a driver for determining an exciting phase which is one step ahead of the current exciting phase as a next exciting phase in response to the pulse signal generated from the signal generator and exciting the stepping motor set in the thus determined exciting phase. In the drive controller, the signal generator generates pulse signals as a pulse signal group at such an interval that the stepping motor cannot respond to the pulse signals and repeatedly generates the pulse signal group by M times at such an interval that the stepping motor can be driven in response thereto so as to rotate the stepping motor in a reverse direction.
