間隔で離間している。 As shown in FIG. 4, the second conduit guide 6a
The guide holes 6a-1 and 6a-2 are arranged in two vertical rows.
The number of holes 6a-1 in one row is an odd number, and the number of holes 6a-2 in the other row is an even number, and the holes in both rows are arranged close to each other, for example, in a staggered manner. . The third conduit guide 6b located between the first and second conduit guides 5, 6a has an equal angular distribution from the first conduit guide 5 as shown in FIG. 6 and is inclined at an angle α°. It serves to smoothly transform each conduit 9 that comes out into the vertical two-row arrangement of the second conduit guides 6a, for example, as shown in FIG. It has guide holes 6b-1 and 6b-2 arranged in two rows. The numbers of these guide holes 6b-1 and 6b-2 are odd and even numbers like the second conduit guide 6a, but both guide hole rows are spaced apart at appropriate intervals. There is.

全に固定するのが有利である。 Of the conduits 9 coming out of the wire guide 5a, an odd number on one side of the vertical center line Y shown in FIG. 6 passes through the conduit guide holes 6b-1 and 6a-1, and an even number on one side passes through the conduit guide hole 6b-2. and 6a-2 to terminate. The printing wires 8 coming out from the tip of each conduit 9 are placed in the lip guide 7 in order from the higher position, starting with the one that is vertically symmetrical in FIG. 6, that is, the one belonging to the right half.
are inserted into the vertically arranged guide holes 7a.
In this case, the third conduit guide 6b adjusts and fixedly supports the conduit 9 so that the tip of the printing wire 8 extending straight from the tip of the conduit 9 coincides with the position of the hole 7a of the lip guide 7. There is. Each conduit 9 is fixedly supported at the first, second and third conduit guides 5, 6a, 6b, and exits from the first conduit guide 5 to guide the second conduit guides 6a in two vertical rows. It undergoes elastic changes in the free space until it is collectively supported by the holes 6a-1 and 6a-2. In order to ensure the support of the conduit 9 by the conduit guides 6a and 6b, both guides 6 of the conduit holder 6 are
Advantageously, an adhesive 11 is placed between a and 6b to completely fix the conduit 9.

ともできる。 The holes 6b-1 and 6b2 of the third conduit guide do not necessarily need to be arranged along an arc, but may be of any shape that allows the printing wire 8 coming out of the tip of the conduit to enter the hole 7a of the tip lip guide 7 in a straight line. If solenoid 3 is attached to bracket 2.
It is possible to make any shape by changing the arrangement of the pipes 9 and the mutual spacing and arrangement of the pipes 9 taken out from the first pipe guide 5. For example, as shown in FIG. 8, the arcuate surface may be completely eliminated. Further, the third conduit guide 6b can also be configured as an adjustment guide whose position can be changed in the longitudinal direction of the conduit 9.

８をリツプガイド７の孔７ａに導いてもよい。 The printing wire 8 whose direction has been adjusted by being fixedly supported by the conduit 9 comes out from the tip opening of the conduit 9 and straightly passes through the tip lip guide 7 at an angle β with respect to the axis Z, as shown in FIG. into the hole 7a. in this case,
Considering the gap or play due to the clearance between the printing wire 8 and the guide hole 7a, this play gives an allowable angle β 0 of the angle at which the printing wire 8 enters the guide hole 7a. Therefore, even if the printing wire 8 enters the guide hole 7a at an angle β, as long as the allowable angle β is within 0 , the printing wire 8 will pass through the guide hole 7a in a hurry, and the printing operation will be adversely affected. I won't give it. This means that the arrangement and spacing of the holes 6b-1 and 6b-2 of the third conduit guide 6b can be changed within the range where the angle β into which the printing wire 8 enters falls within the allowable angle β0 . ing. Note that among the conduits 9 arranged in two vertical rows on the second conduit guide 6a, the centers of the holes of the conduits in one row are made to coincide with the axis Z, that is, β = 0, and the holes in the conduits in the other row are The printing wire 8 may be guided into the hole 7a of the lip guide 7 so that the center of the hole in the conduit forms an angle 2β with the axis Z.

イヤ８の上下方向の調整はほとんど必要なく、ま
た簡単に調整ができるものである。 The deviation or level difference of the printing wire 8 at the tip of the conduit with respect to the hole 7a of the tip lip guide 7 can be made extremely small by dividing each conduit 9 vertically around the center hole 7a of the tip lip guide. Therefore, vertical adjustment of the printing wire 8 by the third conduit guide 6b is hardly necessary and can be easily performed.

る。 For example, as shown in FIG. 1, the conduit 9 is a double conduit made of a material with a low coefficient of friction such as synthetic resin on the inside and a material with appropriate strength and flexibility such as stainless steel on the outside, The outer layer 9b is the first
The third conduit guide 5a or the third conduit guide 6b can be provided until the third conduit guide 6b is exited, and the portion beyond that point can be composed of only the inner layer 9a. In this way, the life of the conduit 9 can be extended. still,
Conduit 9 has its first and third conduit guides 5 and 6
It is also possible to fix with adhesive between b.

As described above, in the present invention, the wire guide means (rip guide 7) has different heights depending on the holes 7a provided in the vertical direction, and furthermore, Since the wire driving means (solenoid 3) is arranged at a predetermined distance from the line, the printing wire 8 does not bend and come into contact with other wires during printing operation, and as a result, deterioration in printing quality can be prevented. It became like that. Further, since the wire driving means is arranged approximately symmetrically with respect to the horizontal line (horizontal center line X) passing through the longitudinal center of the wire guiding means, each hole 7a formed in the wire guiding means The manner of contact with each wire 8 that fits into the hole 7a is vertically symmetrical with respect to the horizontal line, so that the operating state of the wire 8 can be made uniform in the vertical direction, and at the same time, the wear of each hole 7a can be reduced in the vertical direction. It can be made uniform without any variation. As a result, it is possible to prevent damage to the wire guide means over a long period of time and to ensure high quality printing with no variation in the vertical direction. Furthermore, when adjusting the printing force of each wire or when manufacturing the hole 7a portion of the wire guide means, the wires, holes, etc. on the upper side and the wires, holes, etc. on the lower side are connected to each other with the above-mentioned horizontal line as a boundary. Since they only need to be adjusted or manufactured to the same degree, work such as adjustment becomes easier.
