Abstract

The invention provides a dot-line printer enables realize a highly accurate image quality while enhancing the print speed. The printer has a puns P of respective print hammers are shifted by dot pitch in the longitudinal direction. A print head HX must be moved two times when a longitudinal dot is printed. When the interval of a hammer pin is set equal to the interval of longitudinally decimated dot, printing speed is enhanced by a factor of two for longitudinal decimation and when it is combined with lateral decimation, a printer having a 4 * print speed mode is obtained.

Description

Dot-line printer

The present invention is applicable to the printhead of dot matrix printer, by pulling out print point between type between using, when can realizing existing flying print speed, under the situation of a printing, also can obtain high-precision print quality.

Fig. 1 is with the literal " A " with the some matrix representation of indulging 24 of 24 horizontal strokes, the detailed view that adopts existing dot-line printer to print, the left and right directions of figure is that the moving direction along printhead carries out parallel moving, and the above-below direction of figure is to carry out vertical moving along the moving direction of printing.Fig. 2 be expression with the literal of Fig. 1, in the perpendicular direction of the moving direction of printhead, promptly on the above-below direction of figure, with between pull out type and come diagrammatic sketch that the literal of printing " A " is represented, but omit the print point of even number line.

Fig. 3 is existing dot-line printer print head structure and the printing type that expression prints literal shown in Figure 1 " A ", printhead is the printhead H that adopts 12 pins, the printing pin that each printing hammer is set, be with literal each dot spacing with vertical 24 and horizontal 24 s' some matrix representation, make it on the vertical direction of printhead moving direction, be arranged in order mutually and stagger, carry out 12 printing by once moving of printhead, by the mobile printing of carrying out 24 literal " A " of twice printhead.

Between using, pull out the type mode under the situation of pulling out literal " A " and printing,, make print pulling out state at vertical 24 by an action of pulling out printing hammer as Fig. 2.In this case, its printhead H moves, and is identical with a situation of pulling out, and also needs twice.

As mentioned above, existing dot-line printer, printhead H prints pin P only printhead H moving down once with each, only arrange simultaneously printable counting, be to use gapless arrangement and print pin P, with regard to pulling out type between using vertically, on the mobile side and vertical direction of printhead H, even pull out between printhead carried out, also with to improve print speed irrelevant.And under the situation of between carrying out, pulling out, can reduce the quality of printing.

The invention provides a kind of print speed that improves, and can realize the dot-line printer of high accuracy print quality.

The present invention is for addressing the above problem, the feature of the dot-line printer of first invention, be on the dot-line printer that matrix print head prints by swinging, make the printing pin of printhead, by once moving of printhead, the point that is printed, on the perpendicular direction of printhead moving direction, with arranged with the spacing more than the point in adjacent o'clock, when when dialing seal in the ranks with the perpendicular direction of printhead moving direction is enterprising, it pulls out the arrangement of left point and the arrangement of printing pin between not, has identical distance.

The feature of the dot-line printer of second invention, be on the dot-line printer that matrix print head prints by swinging, be provided with by the moving an of printhead, with the perpendicular direction of moving direction on carry out the printhead printed more than two points, literal with the vertical direction that is printed forms a plurality of points in length and breadth respectively simultaneously, be provided with a gap printhead in vertical direction, and between point, be provided with the not printing part more than the point.

The feature of the some bar printer of the 3rd invention, be on the dot-line printer of relevant first invention, by moving of a printhead, and carrying out two printings more than the point with the perpendicular direction of moving direction, the literal that will be printed vertical direction simultaneously forms a plurality of points respectively at portraitlandscape, and after being provided with the printing action in a gap in vertical direction, the printing action by follow-up partly prints the not printing of putting more than 1 between point.

The dot-line printer that has printhead according to the present invention when printing by the printing curve that pulls out between pulling out quilt, owing to can make the number of times that swings of head be lower than half of existing printhead, therefore can be realized flying print.And pulling out between usefulness under the situation that type prints, not only can the printing curve that pull out between quilt be printed, again owing to not identical with existing printing action, also can print simultaneously, therefore can realize high-precision print quality by a reciprocal printing action by a printing curve that pulls out.

Fig. 1 is for representing the diagrammatic sketch of literal " A " with vertical 24 points, horizontal 24 dot matrix;

Fig. 2 is for to pull out the diagrammatic sketch of situation with the literal of Fig. 1 between the above-below direction of figure carries out;

Fig. 3 is for once moving the plane of available 12 existing print head structures that print by printhead;

Fig. 4 is for using existing printhead, the printing type diagrammatic sketch that the literal of Fig. 2 is printed;

Fig. 5 once moves the plane of available 12 print head structures of the present invention that print for expression by printhead;

Fig. 6 represents to use printhead of the present invention, the printing type diagrammatic sketch that the literal of Fig. 2 is printed;

Fig. 7 represents to use the literal of Fig. 1 of printhead of the present invention, the diagrammatic sketch that pulls out between the figure left and right directions carries out;

Fig. 8 represents the literal of Fig. 7 is dialed the diagrammatic sketch of seal between the above-below direction of figure carries out again.

Fig. 5 is illustrated in once moving down of printhead, can carry out the structure of the printhead HX in the embodiment of the invention of 12 dot printings, use common font will pull out the printing type diagrammatic sketch that literal " A " (Fig. 1) prints continuously, printing hammer is the printing pin P of each printing hammer to be arranged mutually in the vertical spacing of each point stagger, for vertical 24 are printed, moving of its printhead HX is identical with existing printhead, also needs twice.

Fig. 6 is an expression printhead of the present invention, pulls out type between use to pulling out the printing type diagrammatic sketch that literal " A " (Fig. 2) prints, and pulls out between vertical 24 quilts and forms 12 points, because its point at interval and to print pin identical at interval, therefore the mobile of head also can carry out once.This situation because the mobile number of times of head only is existing printer half, therefore can make print speed improve 1 times.

Fig. 7 is a moving direction of representing the literal of Fig. 1 is parallel to printhead, promptly pulls out the diagrammatic sketch that type prints between using on the left and right directions of figure, and Fig. 1 only omits the point on right side among the point of left and right directions two points arranged side by side.Usually because its corresponding speed always has the upper limit, therefore, as adopt this mode of pulling out in hammering into shape, the translational speed of its printhead can improve 1 times.

Fig. 8 is expression is moved the literal of Fig. 7 perpendicular to printhead a direction, promptly pulls out the diagrammatic sketch of type between the above-below direction of figure uses, and the print point of even number line is omitted.When it being printed, with regard to Fig. 7, can get 2 times print speed, and with regard to Fig. 1, can obtain 4 times print speed with this printhead.

The feature of printhead of the present invention, be with vertically between the identical at interval hammer pin of the point that pulls out part at interval, pull out 2 times print speed between can improving vertically thus, as take with horizontal between pull out and usefulness, then can obtain the dot-line printer of 4 times of print speed patterns.And can realize high-precision print quality by printing type simply.
