ある。 Next, for comparison with the present invention, the conventional eye structure of this type of thin plate member will be explained with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing the process of attaching the paper guide 2 of the paper guide plate to the side plate 3, which forms part of the frame of a small-sized printer, with the aid of the fingers. It is an enlarged explanatory diagram of the main part.

材である。 In the figure, a notched recess 3b is provided on the upper side of the side plate 3 (first member) made of a thin steel plate, and a protruding piece 3a is formed at the bottom of the notched recess 3b. As shown in the second figure, the height of the protruding piece 3a is formed slightly lower than the upper side of the side plate 3. In addition, a paper guide 2 made of thin plate stainless steel, etc.
(The second member) is formed with a convex portion 2b that matches the notch recess 3b, and a hole 2a for inserting the protrusion 3a is bored in the convex portion 2b. 4. A jig for minimizing changes in the shape of the parts during fitting. 1 is a punch with two prongs at the tip, that is, a fitting member.

実に結合する。 In addition, in Fig. 2, L P is the fit pitch of the fitting member 1, L W is the width of the protruding piece 3a, L N is the width of the hole 2a,
These are in the relationship L P <L W <L N. Figure 2 shows a state in which these dimensional relationships are manufactured according to the initial machining accuracy, and when the locking member 1 is pushed down from the state shown in Figure 2, the locking member 1 is moved as shown in Figure 3. The shoulder portion 3a-1 of the protruding piece 3a is pushed apart, and the deformed shoulder portion 3a-1' is inserted into the hole 2 of the paper guide 2.
It covers over the a edge and reliably connects the side plate 3 and paper guide 2.

ため、通常、突片３ａと孔２ａとに若干のクリア
ランスを持たせて寸法設定を行ない、突片３ａと
孔２ａとが嵌合不能になるという事態を回避して
いた。 By the way, press parts such as the side plate 3 or the paper guide 2 are generally prone to dimensional errors that are difficult to avoid during manufacture. Therefore, if the width L W of the protruding piece 3a and the width L N of the hole 2a are in the relationship L W =L N or L N <L W , the protruding piece 3a cannot be inserted into the hole 2a. The dimensions of the protruding piece 3a and the hole 2a are set with a slight clearance, thereby avoiding a situation where the protruding piece 3a and the hole 2a cannot be fitted together.

変形させる恐れがあつた。 However, due to dimensional errors that are difficult to avoid during manufacturing, when the paper guide 2 and the side plate 3, which are manufactured so that the width of the hole 2a is larger and the width of the protrusion piece 3a is smaller, are combined, the protrusion as shown in the fourth figure is produced. The clearance between the piece 3a and the hole 2a becomes larger. When the locking member 1 is pressed down in the state shown in the fourth figure and the locking is performed as shown in the fifth figure, the shoulder 3a-1' (deformed part) of the protruding piece 3a is pushed out onto the edge of the hole 2a of the paper guide 2. This resulted in a significant decrease in bond strength and decreased reliability of the printer as a whole. (The two-dot chain line in FIG. 5 shows the vertical vibration caused by the vibration of the paper guide 2.) In addition, in order to increase the strength of the lock, the amount by which the lock member 1 is pushed down is increased, and the shoulder portion 3a-
If the paper guide 1 is greatly deformed, the side plate 3 will buckle and deform, and the shoulder portion 3a-1 will be deformed non-uniformly, leading to bending, cracking, and possibly deforming the paper guide 2.
この事態を避ける為、部品加工精度の向上を企

つた。 In order to avoid this situation, attempts were made to improve the accuracy of parts processing, but the management of mold accuracy, press processing, etc. became difficult and complicated, resulting in a significant drop in productivity and high costs.

番号を付し、その詳細は省略する。 The present invention has been made in view of the above points, and details of the present invention will be explained below with reference to an embodiment shown in FIGS. 6 to 9. Similar to the prior art described above, this embodiment shows a structure in which a side plate 3 of a small printer and a paper guide 2 fit together, and the same parts as in the prior art are given the same numbers and the details thereof are omitted.

図参照）。 In the figure, a 6-fit punch has a second punch part (second jaw part) 8 with a forked tip, and a second punch part 8 with a forked tip.
The first punch part (first eye part) 7 is slidably held in the vertical groove 10 of the punch part 8 so as not to fall off. The first punch portion 7 is always pressed downward in the drawing by a spring 9 housed in the vertical groove 10, and during the tightening operation, the tip of the first punch portion 7 is connected to the second punch portion. 8 protrudes downward in the figure by a predetermined amount (7th

となつた場合を示している。 7 to 9 are enlarged explanatory views of the main parts, and in each of these figures, the thin plate-like protrusion 3a of the side plate 3 (first member) and the hole of the paper guide 2 (second member) are shown. 2a is the fourth and fifth clearance of the conventional example mentioned above.
As in the figure, this shows the case where the maximum value is due to dimensional errors that are unavoidable in manufacturing.

With the top of the protruding piece 3a protruding from the upper surface of the paper guide 2, insert the punch 6.
When you press down, the first punch part 7 first hits the protrusion 3a.
As shown in FIG.
A first stage bulging shoulder portion 3a-s1 is formed. At this time, the first punch portion 7 resists the spring 9 and presses the vertical groove 1.
It has slightly fallen to 0.

る。 If you press down the punch 6 further from this state,
The first punch part 7 is completely retracted into the vertical groove 10, and the second punch part 8 comes into contact with the first stage bulging shoulder part 3a-s1 and presses it apart, thereby forming a second punch part 7.
A step bulge shoulder 3a-s2 is formed, and the second step bulge shoulder 3a-s2 is placed over the upper edge of the hole 2a of the paper guide 2. As a result, the side plate 3 and paper guide 2
Since the shoulder parts 3a-s are reliably connected to each other and have a second stage configuration, the shoulder parts 3a-s are easily deformed, and there is no possibility of cracking or breaking. Since there is no need to increase the amount of deformation of 3a-s, the side plate 3
Moreover, there is no possibility that the paper guide 2 will be buckled or deformed. In addition, in FIGS. 7 to 9, the protrusion 3a and the hole 2a
The case where the clearance between the
If the clearance is smaller than this, it will be determined in the same process as above, and the strength of the joint will be further improved.

Although the structure of the paper guide 2 is taken as an example, the present invention is not limited to this, and the present invention is not limited to this. It is applicable if it is fitted with the members of
In addition, the protruding piece and the first member do not need to be of the same thickness or made of the same material; almost any material that can be fitted with the protruding piece can be used. Further, in the embodiment described above, the first punch portion 7 (first eye member) presses the central portion of the protruding piece 3a, including the vicinity of the shoulder portions 3a-s of the protruding piece 3a. However, it is also possible to press only the vicinity of the shoulder portions 3a-s with the first punch portion 7 to form the first stage bulging shoulder portions 3a-s1.

供可能となり、その産業的価値は大きい。 As described above, according to the present invention, the second punch portion having a bifurcated tip and the first punch portion held inside the second punch portion so as to be slidable and not fall off. Using the preparation member, first spread out the shoulders of the protrusions with the first eye member, and then spread out the expanded shoulders (first stage bulging shoulders) with the second eye member. Since this method is used to further expand and cover the periphery of the hole or notch in the second member, the strength of the fit is stable even if the clearance between the protrusion and the hole (or notch) becomes somewhat large. Therefore, even if attempts are made to reduce the accuracy of parts processing, it is possible to provide a structure that is always stable, and it is possible to provide a low-cost, highly reliable product, which has great industrial value.
