Abstract

PURPOSE:To perform a high-quality color recording without mixed colors by a method in which a plural rows of projections are elastically supported on a rotary drum in the printing direction, a specific color of ink is supplied, and a striker is moved and struck in the direction of printing. CONSTITUTION:In dot printing of black color, a rotary drum 8 travels with a printing head 15 and an ink roller 18 to the position of recording, and the printing head 15 moves in the drum 8 so that the printing hammer 16 is faced to the projection 14 of the arm of the black section 8a. In the recording position, the rotary drum 8 is turned while being coated with different inks by sections 18a- 18d of the ink roller 18 so that the arms of projections 13 to be recorded come to the front of recording. By striking of the arm projection 14 of the printing hammer 16, the projection is moved forwards by elastic deformation of the arm, and dots are transferred to a recording paper 2 on a platen 7 by the projection 13. The operations are repeated for other colors for color recording. A high- quality recording without mixed colors can thus be obtained.

At the same time, the recording paper 2 is moved in the direction of arrow B by a distance equal to the moving distance of the print head 15 within the rotating drum 8, and the arm portion 11 of the yellow part 8c having the protrusion 13 corresponding to the next dot to be recorded is placed in front of the recording surface. After the rotary drum 8 is rotated in the direction indicated by the arrow, the print head 15 is driven once and the print hammer 16 hits its arm 11, so that the protrusion 13 coated with yellow ink is recorded. The paper 2 is struck, and yellow dots are transferred onto the recording paper 2.

If yellow dots are to be superimposed on the black dots recorded earlier, without rotating the rotating drum 8,
It is sufficient to hit the arm portion 11 of the yellow portion 8c directly below the arm portion 11 of the black portion 8a that was hit earlier. In this way, by overlapping a plurality of colors on the same dot, dots of colors other than the above four colors can be formed. For example, if you overlap a dot of f ink on a yellow dot, you will get a red dot.

In the above embodiment, recording was performed using an ink roller, but other ink supply media such as an ink ribbon may also be used. Further, although the number of rows of protrusions on the rotating drum is four, and color recording is performed using four colors as a base, the number of rows and base colors is not limited to this. Further, in the above embodiment, recording was performed by hitting four rows of protrusions with one hitting means (print head), but it is of course possible to use a hitting means with multiple waves.
