Abstract

PURPOSE:To enable the switching employment of high-density printing and high- speed printing by sliding a plurality of lines of wire pin guides which are provided slidably at the end of a wire impact type printer head. CONSTITUTION:In a serial printer of wire impact dot type, a number of lines (three lines in the figure) of pin guides 5a1-5a3 each having a number of wire pin guide holes 5b are provided at the end of a printer head 5, and these guides are made slidable relatively. When high-density printing such as word processing is performed, the pin guides 5a1-5a3 are slided to increase the apparent density of pins in the vertical direction. When high-speed printing such as data processing is performed, the pin guides 5a1-5a3 are made to coincide in the horizontal direction and are operated alternately. It is suitable to employ a crank shaft 23 with crank arms 23a and 23b for sliding the pin guides 5a1-5a3.

Motokyu, carrier 131KFi
The print head 21 is installed in the ink ribbon cassette (20) with a 9-carved shape, and the print head 21 forms a print with a welfare dot. 21aii As shown in Fig. 2 and S-, core IK:! IKmm
The gamma gussets 8 are arranged so that Amate, 7
A holding s3a with a printing wire 4 attached thereto is attached to the tip of the sill, and the amatea 3 is elastically supported by a support spring 6, and one end of the support spring 6 is attached to the foot of 1.
A permanent stone 8 is sandwiched between the aKIl and bOa road portions 7m and 7b, and the core 1 and the armature 3 are arranged in a U-shape.

A Confucian bribe *yc is running out from Daihiro section 7a to Ryobi of Amatea 8, making counterfeit money through a gap. 9. When the printing magnet 21a is not operating, the magnetic force of the permanent magnet 8 causes the amateur 3 to be attached at the angle of AlI/Cl1. The print head 21 has a print head 21, as shown in FIG. The printing wire 4 is guided by the pin hole 6bK of the pin guide 61 at the tip of the center self-extruding guide 7 frame in the center, and the printing wire 4 is guided in 2 rows K as shown in #ll5llK.
There is an IE row. The Ingaku magnet stones are arranged radially together with the magnetic path section 7b as shown in the sixth section.

Since it has a configuration like O, there are 10 print magnets in the print head! laO
With the energy stored by the support lock 6, it flies upward to the side of the amateur 8 section 7a, that is, in Fig. 13.

Then, the printing wire 4% is pushed out in the direction of arrow E, and while selectively moving the plurality of printing magnets 21 & in the print head 21, the 1st K! As shown in , the print head 21 is moved along with the carrier 18 in the directions of arrows C and D to print on the print paper 11. In this case, the print quality depends on the dot 011NK. When printing a 0 character, there is a demand for high-speed printing and speedy data II & output, even if the print quality is somewhat degraded. On the other hand, Buntesha Moderation for Word Goosessing has improved printing quality and has sentence #P similar to that of major typefaces, such as matrix letters.

This marks the quality of the print as an official document from the company and makes it easy to read with a line optical character reader! #Quality is the key. In order to reduce these O conditions to 1iJ, compared to conventional data processing/MO printing, word processing printing uses a method to increase the dot writing quality by dividing characters into horizontal and vertical directions. ing. First, as a method for improving the printing quality in the horizontal direction, (1) the printing speed is omitted and printing is performed closer to the horizontal dot spacing for data gusseting. (2)

As a method of raising the printing part 11, the printing wire 40
For example, 1 column 1111 for printing with multiple columns.
It is generally known that if the first row is used to print odd numbers and the second row is used to print odd numbers, then the first row can be printed at twice the speed of the odd print head 21.

The printing wire is 40 vertically arranged (for example, the pitch is Q, about 3 to QJm/m), and the above movement amount is 8
In the case of 3 rows, α1m/al1 is O that is counted at 1/3 pitch.
Because it has such a configuration, this print head! 1, when printing for printing on the meeting word 4-, turn the lever 24 once and place it in the position of the driver, and the pin guides 1sal to 5a will move like lIIg12mcJ. , k'/hole SbK guided good printing wire 4
Since the lines are in a staggered arrangement, it is difficult to print densely in the vertical direction using the printing wire 4 in the Australian number sequence. There are 11 things to do. In other words, since vertical IFK printing is performed, there is no need for slight line breaks, and the speed is three times that of the IN layout.

! It is of course possible to move the pin guides 5 & 1651m using a magnet mechanism or a pulse controller, etc., or automatically using printer input information or switches. Although the example has been explained, there is a method in which the entire guide 7 frame 6 and the pin guide 5at to 5ml are divided into K1 parts and moved in the same way, or the printing head 21 with one row of the Hiro printing wire 4 is used.

FIG. 15 is a front view showing an example of a different application of the Figure 15 line. In the figure, lO/ is the platen, 16I to 16. The same parts as in Figure 1 are indicated by the same reference numerals.

The difference between No. 1211 and No. 1811 from the embodiment shown in Figure 11 of the 7th cabinet is the print head! It-! Im to the printing direction - perpendicular direction, 1IIKs? The print heads 311 to 21 arranged in the vertical direction can be operated at the same time since they have the following characteristics: The Shuttle P printer is capable of printing three lines at the same time and therefore enables high-speed printing.
r1nt@r), where a plurality of print heads 21 are arranged at intervals in the row direction, and if the width of the print paper 11 is narrow as in Ryobakin O, the print heads 21 cannot be used effectively and high-speed printing cannot be performed. According to the heather application example, the speed of printing is increased regardless of the width of the printing paper 11.In this case, if the individual print heads 21+-211 are configured as in the above embodiment, it will be more effective. The coming is 6° 4 is 3 above
Although the individual printing heads 31 to 21sai are mounted on L carriers 1B' and driven, as a different application example, as shown in Fig. 915, it is possible to control the space by driving each print head independently. Head 21. ~IIm
of]! can be used efficiently. The trench nine platen 10 prints flat mKS pieces, deff1ls~! 1m
#Although an example in which printing is performed horizontally and vertically is shown, it is also possible to use a round platen if the print heads 211 to 21m are arranged in an arc shape.

ω The effect is better than my WA! As explained above, according to the present invention 11, printing can be performed by changing the printing density by moving the pin guides of each row of the II number row printing wire by a predetermined amount in the row direction, so that the printing wire can be used efficiently. It can be used frequently, and has the advantage of being able to print at high speed and high quality for word processors, and for data processors to print at high speed on black pages.

Furthermore, by arranging a plurality of print heads in an aK arrangement as in the applied example, there is an effect that efficient high-speed printing can be performed regardless of the width of the printing paper.
