Abstract

PURPOSE:To provide the subject system in which a distance between adjacent trains of pin wires aligned in a plurality of trains is set to a size except that which is an integral number times as long as a distance between dots being printed, the number of electromagnets simultaneously energized reduces sharply, and an interference between the electromagnets reduces. CONSTITUTION:A distance P between pin wire trains L1 and L2 is set to a size except that which is an integral number times as long as a distance (p) between dot trains, and the wire pins L1 and L2 are normally kept from being simultaneously present on trains l1-l5, being printed, on a recording medium. The wire pins in the two trains L1 and L2 may be alternately driven, and when driven alternately, the drive signal of the wire p in the train L1 is prevented from overlappig with that of the wire pin in the train L2. An effective current and a peak current of a power source reduce.

One of the printing methods of this wire dot printer is to arrange the bin wires in multiple rows.
This is printed by selectively driving the dots at predetermined intervals. There is a way to do it. -Is diagram 1 an example of a printing plate used in such a printing method? FIG.

This print head is of the so-called open type, and the armature breather 3 is normally moved between the magnetic core 2 by the magnetic force of the permanent magnet 2.
However, by energizing the coil 22, the magnetic field of the permanent magnet 2 is canceled out, and the restoring force of the bar 4 releases arches I and A3 from the magnetic core 21. At this time, the bin wire S is guided by the blur guides 31 to 33 and the bin guide 6, is projected from the pin guide 6, and strikes the ink ribbon 7, print medium 8, and platen 9, so that dots are printed on the print medium.

FIG. 3 is a standard diagram for explaining the relationship. In this case, the odd numbered dots in each column of dot arrays 11 to 13 are printed by the bin wire in column L1, and the even numbered dots are printed by the bin wire in column L2. In other words, when the bin wire moves to the right (arrow) with respect to the medium, first when the bin wire of column L2 passes column 11 on the medium, it prints the even-th mark dot, and then column L1 prints the dot of column 11Q.
When passing, all odd-numbered dots are printed to complete the printing of row 11.

(3) Prior Art and Problems In the printing system described above, the interval P between the rows L1 and L2 of the bin wires is conventionally designed to be an integral multiple of the interval p between each row of dots. Therefore, in FIG. 3, if Pkp is twice, the bin wire of column L1 is on column ll on the medium? At the time of passing, the bin wire of row L2 reaches above row 13 on the media, and the bin wires of two rows L1 and L2 are driven simultaneously to the even numbered dot of row 11 and the even numbered dot of row 13, respectively. is printed. Each bin wire is driven by an independent electromagnet, and when the number of bin wires is 24 pins, 24 electromagnets are used. When a large number of these electromagnets are operated simultaneously, a phenomenon occurs in which they interfere with each other. When such interference occurs, there is a problem in that printing energy decreases and effective current increases. The decrease in printing energy results in a decrease in the stroke amount of the bin wire, resulting in a total decrease in print density and an increase in the yield and sound length of the 9114 product, which has a narrow tolerance range such as the distance between the pin guides 21277. Furthermore, there is a problem that the peak current of the power supply increases as the number of electromagnets that operate simultaneously increases.0(4) Purpose of the Invention The purpose of the present invention is to reduce interference between each electromagnet, thereby improving printing quality. It is an object of the present invention to provide a printing method that can increase the speed and reduce the effective current.

Another object of the present invention is to provide a printing method capable of reducing the peak current of a power supply for driving bottle wires. In the printing method of a printing erodible dot printer, by selectively driving the bin wire at a predetermined dot interval while moving the bin wire relative to the printing medium, the interval between the rows of the bin wire is set to the interval between the printed dots. 0(6) Embodiment of the Invention Next, an embodiment of the present invention will be described in Example 11 using the print heads shown in Figures @1 and 1I2.

FIG. 4 is a diagram for detailed explanation of the present invention 011
In Figure 4, the white circles placed on columns L1 and L2 indicate the position of the bin wire, and the black circles on columns 11 to 15 are printed by the bin wire and are marked on the return medium. What if all the bin wires in each row are printed at the same time for convenience? However, in reality, the bin wires in each column are selectively driven depending on the type of characters or graphics to be printed. Furthermore, in this embodiment, the interval between the two rows L1 and L2 of the bin wires is 2.5 times the interval between the rows 11 to 15 of the dots. The condition at the time of passing the upper column #2 indicates 0 At this point, the bin wire of column L2 is recorded on the medium L 0 0 which exists between the two columns I4 and 15 Therefore, at this point only the wire bin of column L1 Just drive it.

The i ear is located midway between the two a rows 12 and 13 on the recording medium. Therefore, at this point, it is sufficient to drive only the wire bins in row L2.

In this way, the two rows of wire bins L1 and L2 #i are never simultaneously present on the column to be printed on the printing press, and therefore the wire bins of the two rows L1 and L2 are alternately driven. In addition, during this alternate driving, it is necessary to make the drive signal for the wire bin in row 1 and the drive signal for the wire bin in row L2 at one angle so that they do not overlap.

(7) Effects of the Invention As is clear from the above embodiments, the printing method of the present invention significantly reduces the number of electromagnets that must be energized at the same time, which not only reduces the peak current of the power supply. In addition, interference between the electromagnets is improved, and there is more leeway in setting the distance between the bin guide and the platen, and the effective current for driving the electromagnets is also reduced.
