PURPOSE:To obtain a small-sized printing device fitted for output of a computer and the like by providing a type wheel whereon a type belt is wound, a hammer built in the type wheel and a plurality of ink rollers provided on the outer periphery of the type wheel on a base cylinder having a plurality of small holes. CONSTITUTION:A printing paper sheet P is fed upward every one line. The hammer H is built inside the type wheel D prepared by winding a rubber type belt G provided with a plurality of printing types C1-C4 on the base cylinder K, and the inside projections GT of the rubber type belt are struck by the hammer to make one of the types C1-C4 of the rubber type belt G project onto the sheet P. Since black ink of a black-ink roller 11 is applied to the type C1, red ink of a red-ink roller to the types C2 and C3 and white ink of a white-ink roller 13 to the type C4, for instance, type patterns can be transferred onto the printing paper sheet P with respective colors. |
