[Table 1]

Chip storage case K As shown in FIGS. 1 and 2, this chip storage case K
A main body 1 that forms a rectangular box that opens upward, a chip holding plate 2 that is fitted on the opening edge of the main body 1 and that has a chip holding hole; And a lid 3 which is attached and opened with a one-sided opening action, and has a rectangular parallelepiped shape as a whole. Thus, the chip T is held via the chip holding hole 5 formed in the chip holding plate 3. The main body part 1, the chip holding plate 2, and the lid part 3 are made of synthetic resin, and polypropylene (PP) is selected as a suitable material, but other synthetic resin materials are not excluded.

Hereinafter, a detailed configuration of each part will be described. Main Body 1 (See FIGS. 1 and 2) The main body 1 forms a rectangular box that opens upward from the four surrounding walls 10 and the bottom plate 11. An opening edge 12 is formed at an upper portion of the surrounding wall 10 of the main body 1 with a predetermined height and retreated from a surface of the surrounding wall 10 through a step having a predetermined width. 12a is an outer surface of the opening edge portion 12, and 12b is a step portion thereof. The width of the step portion 12b at the front and rear portions of the opening edge portion 12 is larger than the width of both side portions. A vertical groove 13 is formed in the center of the outer surface of the opening edge 12, and a horizontal groove 14 is formed in the lower end. The vertical groove 13 and the horizontal groove 14 both have a curved cross-sectional shape and communicate with each other. In addition, this main body 1
It is composed of the upper surrounding wall portion 1A and the bottom plate portion 1B and can be disassembled and assembled. However, it is needless to say that they may be integrated. The body 1 further has a notch 16 formed at the rear of the side surface of the surrounding wall 10, and a pin hole 17 is formed in the notch 16 in a penetrating or blind hole shape.

Chip holding plate 2 (see FIGS. 1 to 7) The chip holding plate 2 is mounted on the opening edge 12 of the main body 1 in a fitting manner, and has a flat plate shape and holds a large number of chips. The main body is a holding plate body 20 having a certain thickness and having a hole 5, and a flange 21 which is stretched vertically and vertically at the front and rear edges of the holding plate body 20 with the same height. The vertical ridge 23 is formed vertically in the center on the side surface.
Further, a horizontal ridge 24 is provided on the upper and lower edges with a predetermined length.

A detailed configuration of the chip holding plate 2 will be described with reference to FIGS. (Holding plate body 20 and chip holding hole 5) The holding plate body 20 has a rectangular flat plate shape with a constant thickness, and the distance in the left-right direction, that is, the width is substantially equal to the width of the opening edge portion 12, and the front-back direction. Is substantially equal to the vertical width of the opening edge 12. The chip holding hole 5 is provided in the holding plate body 2.
Many are drilled at predetermined intervals at zero. In this embodiment, they are arranged in 12 columns and 8 rows, and adopt a standard mode. However, the present invention is not limited to the number and arrangement. The chip holding hole 5 is formed in the chip holding plate 20 in a circular and penetrating shape.
However, a small diameter portion 7 is drilled through the shoulder 8 on the back surface side. On the small-diameter portion 7 side, that is, on the back surface of the chip holding plate 20, ribs 26 are provided so as to project perpendicularly in the vertical and horizontal directions. The rib 26 is omitted as appropriate. Holding plate body 2
An intermediate portion of the total thickness of the thickness 0 and the thickness of the rib 26 forms the center plane of the chip holding plate 2. Therefore, when the rib 26 is omitted, the intermediate portion of the holding plate body 20 forms the center plane of the chip holding plate 2. FIG. 6A shows an enlarged cross section of the chip holding hole 5. Here, Φ indicates the diameter of the large diameter portion 6 and φ indicates the diameter of the small diameter portion 7. Here, assuming that Φ is 6.45 mm and φ is 4.85 mm, No. 2 and No.
Nos. 4 and 7 are inserted from the large-diameter portion 6 on the front side and held and held. No. 1, No. 3, No. 5, and No. 6 are inserted from the small-diameter portion 7 with the chip holding plate 2 turned over. Is held and held. Fig. 6 (b)
Shows another embodiment of the chip holding hole 5A, in which a large diameter portion and a small diameter portion are tapered and continuous.

(Flange 21) The flange 21 is stretched vertically and vertically at the front and rear edges of the holding plate main body 20 and over the same height, and the height matches the height of the opening edge 12. The outer surface 21a of the flange 21 is formed as a curved surface having a large radius of curvature, that is, a gentle curved surface. On the inner surface, as described above, the vertical ridge 23 is provided at the center in the vertical direction, and the horizontal ridge 24 is provided at the upper and lower edges in the horizontal direction. The vertical ridge 23 and the horizontal ridge 24 both have a convex curved surface. Thus, the vertical ridge 23 is formed on the opening edge 12
And the horizontal ridges 24 are slidably fitted into the horizontal grooves 14. In the flange 21,
An important property is that a slight elasticity is imparted. This elasticity can be given to the flange 21 itself,
Alternatively, elasticity is imparted to the entire chip holding plate 2 including the holding plate main body 20, and either or both of them are adopted.

Next, with reference to FIG.
The dimensional relationship between the grooves 13 and 14 and the engagement between them will be described in detail. FIG. 7 shows the schematic structure, and (a)
The figure shows the external configuration of the inner part of the flange 21 of the chip holding plate 2, and (b), (c), (d) the figure is bb, cc, d in the figure (a).
4 shows an enlarged cross section taken along line -d. As shown in the figure, the protrusion height t1 of the vertical protrusion 23 and the protrusion height t2 of the horizontal protrusion 24 are:
The heights are almost the same, and r1 is larger than r2 for each of the radii of curvature r1 and r2 on the outer surfaces of the vertical ridge 23 and the horizontal ridge 24. In other words, the outer curved surface of the vertical protrusion 23 is a curved surface that is looser than the outer curved surface of the horizontal curved surface 24. Furthermore,
In the length a of the vertical ridge 23 and the length b of the horizontal ridge 24,
The overall length (2b) of the horizontal ridge 24 is sufficiently larger than the length a of the vertical ridge 23. It should be noted that shallow cut grooves 26 are formed on both sides of the vertical ridge 23 in parallel with the vertical ridge 23.
7E and 7F, the ridges 23 and 24 and the grooves 13 and 1 are shown.
4 shows an engagement relationship with the fourth embodiment. That is, the vertical ridge 23 and the vertical groove 1
3 is looser than the engagement between the lateral protrusion 24 and the lateral groove 14. Further, the vertical ridge 23 and the vertical groove 13
The engagement length between the lateral protrusion 24 and the lateral groove 14 is sufficiently longer than the engagement length between the horizontal protrusion 24 and the lateral groove 14. Therefore, when a certain force is applied, the engagement between the vertical ridge 23 and the vertical groove 13 is more likely to be disengaged than the engagement between the horizontal ridge 24 and the horizontal groove 14.
That is, when the flange 21 of the chip holding plate 2 is fitted into the opening, it exhibits a high resistance to upward pulling, a small resistance to being pulled out in the horizontal direction, and can be easily pulled out in the horizontal direction. . In addition, the cut groove 26 adds elasticity in the vicinity including the vertical ridge 23. Furthermore, these dimensional relationships are not essential, and the point is that
It is essential to have a relationship sufficient to perform the function, and various designs can be changed depending on the material and other factors.

The structure of the flange 21 is not limited to the illustrated example.
It can be modified within the scope of the essential matter. That is, the outer side surface 21a has a linear shape, and the height of the flange 21 does not necessarily need to match the height of the opening edge portion 12, and may be higher or lower than the opening edge portion 12.
When the height of the flange 21 is low, the lateral groove 14 of the opening edge 12 is moved upward. The lateral protrusion 24 may be moved upward in the flange 21. In this case, of course, the position of the lateral groove 14 is changed correspondingly.

The lid 3 the lid 3 is, without a rectangular box-like shape which opens with a the enclosure 30 and the top plate 31 of the four circumferential downward, vertically wings 32 at the rear portion of the enclosure 30 on both sides are downwardly A pin 33 protrudes inward from the inner surface of the wing portion 32. Thus, the wing portion 32 fits into the cutout recess 16 of the main body portion, and the pin 3
3 is inserted into the pin hole 17. When the lid 3 is in the closed position, the inner surfaces of the front and rear portions of the surrounding wall 30 are on the outer surface of the flange 21 of the chip holding plate 2 and
Are located on the side surfaces of the opening edge 12 of the main body 1 with a margin. Further, the lid 3 does not hinder the pulling-out operation of the chip holding plate 2 in the lateral direction at the fully opened position (FIG. 2).

Other Configuration FIG. 8 shows a joint between the upper surrounding wall 1A of the main body 1 and the bottom plate 1B. The lower end of the surrounding wall portion 1A is made thinner, and a ridge 35 is formed on the outer surface of the outer wall portion so as to bulge continuously in four rounds.
An upper groove 36 and a lower groove 37 are recessed around the periphery of the bottom plate portion 1B over four circumferences, and the upper groove 36 receives the lower end portion of the surrounding wall portion 1A together with the ridge 35. The ridge 35 fits into the concave portion 36a on the inner wall surface of the upper groove 36 to keep watertight. Upper groove 3
6 is widened by a wide portion 36 b facing the inner chamber side of the main body 1, and the upper surrounding wall portion 1 </ b> A fitted into the upper groove 36.
A sub-groove 38 is formed with the inner wall surface. This sub-groove 38 stores water droplets that are condensed on the inner wall of the upper surrounding wall 1A. Lower groove 37
Imparts appropriate elasticity to the bottom plate 1B, and facilitates the fitting operation of the upper surrounding wall 1A into the upper groove 36.

(Operation / Effect of the Embodiment) The chip storage case of the embodiment configured as described above is used and exerts the following effects. (Assembling) Assembly and removal of the present chip storage case K composed of the main body 1, the chip holding plate 2, and the lid 3 will be described. <Assembling and Opening / Closing Operation of the Lid 3 to the Main Body 1> The wings 32 of the lid 3 are pushed into the cutout recesses 16 of the main body 1 with a pushing force, and the pins 33 are inserted into the cutout recesses 16. Into the pin hole 17 of FIG. When the wings 32 are fitted, the wings 32 are slightly elastic and thus are pushed out and returned to the original state with the fitting of the pins 33.
There is no extraction of 3. The assembled lid 3 is a pin 33
It is opened and closed around. In the open state, the rear surface of the lid portion 3 abuts against the rear edge of the main body portion 1 and stops at the maximum opening (FIG. 2).
reference). <Assembly and Removal of the Chip Holding Plate 2 from the Main Body 1> When the chip holding plate 2 is mounted on the opening edge 12 of the main body 1, the vertical projection 23 at the center of the flange 21 below the chip holding plate 2 is used. Is inserted into the vertical groove 13 of the opening edge portion 12 and pushed in with its guiding action. Since the flange 21 has some elasticity, the lateral protrusion 24 on the lower edge of the flange 21 is allowed to spread and spread, and the horizontal protrusion 24 on the lower edge of the flange 21 is fitted into the lateral groove 14 of the opening edge 12 and mounted. Is done. At this time, if the upper flanges 21 of the chip holding plate 2 are squeezed with a predetermined force, the spreading action of the lower flange 21 is promoted and the mounting action is facilitated. The flange 21 returns to its original state with the fitting of the lateral protrusion 24 into the lateral groove 14, and the chip holding plate 2 is pressed against the opening edge 12 by the elastic action of the flange 21, and there is no play. When the chip holding plate 2 is to be removed from the main body 1, the lid 3 is opened to the maximum opening, and the chip holding plate 2 is pulled out along the lateral groove 14 with a predetermined force. At this time, the lid 3 does not hinder the chip holding plate 2 from coming out.
3 is easily disengaged from the vertical groove 13, the elastic force of the flange 21 is small, and the chip holding plate 2 can be easily pulled out by the elastic action of the flange 21.
The mounting of the above-mentioned chip holding plate 2 exerts the same effect in any state of the chip holding plate 2 in the forward position and the reverse position. Further, when a lifting force acts on the chip holding plate 2, the chip does not easily come off within the range of the predetermined force due to the engagement of the lateral ridges 24 with the lateral grooves 14.

(Method of Loading Chip T) Next, a method of loading the chip T using the chip storage case K will be described. FIG. 9 shows how to carry out the first loading method. FIG. 9A shows the forward position of the chip holding plate 2.
The chip T is inserted from the large-diameter hole 6 side of the chip holding hole 5, and the step portion 104 is locked on the surface of the chip holding plate 2,
The tip 102 of the chip T is loaded through the large-diameter hole 6 and the small-diameter hole 7. FIG. 9B shows the chip holding plate 2 in the reverse position, in which the chip T is inserted from the small-diameter hole 7 side of the chip holding hole 5 and the step portion 104 is locked on the surface of the chip holding plate 2. Will be loaded. Thus, the chip holding plate 2 can correspond to two types of chips T having different outer diameters and inner diameters of the step portion 104. In another chip holding plate 2, the large diameter holes 6 and the small diameter holes 7 of the chip holding holes 5 are formed with different diameters. Thereby, the other two types of chips T
Can respond to. In this manner, a plurality of types 2
One chip holding plate 2 can deal with each type. Then
If this chip storage case K is used, a conventional chip T
The types of chip holding plates manufactured for each type can be halved.

FIG. 11 shows still another chip loading method. In this embodiment, a thin plate 4 separate from the chip holding plate 2 is prepared. That is, the thin plate, that is, the chip holding thin plate 4 keeps the same phase as the chip holding hole (first chip holding hole) 5 of the chip holding plate 2 and has a smaller diameter than the minimum hole diameter of the first chip holding hole 5. The thin plate 4 has a second chip holding hole 9 and is used by being superposed on the chip holding plate 2. The chip holding plate 2 may be at either the forward position or the reverse position. FIG. 11 (b) shows the overall configuration of the chip holding thin plate 4, 4a is a main body portion in which the second chip holding hole 9 is opened, 4b is a flange portion stretched on the front and rear edges,
The chip holding thin plate 4 is fixed to the chip holding plate 2 by bringing the flange portion 4b into contact with the inner surface of the flange 21 of the chip holding plate 2. Then, this chip holding thin plate 4
Is used for loading chips T that are not applicable to the chip holding plate 2 described above. According to this, it is possible to cope with three types of chips T together with the chip holding plate 2 described in the above embodiment.

Another usage of the chip holding thin plate 4 will be described.
That is, a plurality of chip holding thin plates 4 having different diameters of the second chip holding holes 9 are prepared, and are used by being superposed on the chip holding plate 2. In this case, the diameter of the chip holding hole 5 of the chip holding plate 2 may be one, and the diameter may be sufficiently large. All chips T are supported by the chip holding thin plate 4. The chip holding thin plate 4 is a thin plate, is easy to manufacture, and the manufacturing cost can be further reduced.

The present invention is not limited to the above embodiment, and various design changes can be made within the scope of the basic technical concept of the present invention. That is, the following embodiments are included in the technical scope of the present invention. In the present embodiment, the flange 21 is shown to be stretched up and down, but may be a flange only below. FIG. 12 shows another configuration of the main body 1 of the chip storage case. In this embodiment, the main body 1 is integrally formed, and the surrounding wall 10 has a cavity 40 that opens downward. The cross-sectional shape of the chip holding hole 5 is different from the circular shape of the embodiment.
Any suitable shape such as a polygon, a quadrangle or more, a polygon or an ellipse can be used.

The types of application can be expanded, the types of chip storage cases can be reduced, and the manufacturing cost can be reduced. In addition, the chip holding plate is pressed against the opening of the case body by the elasticity of the flange, so that there is no backlash,
The chip is held stably. In the vertical engagement between the opening of the main body and the flange of the chip holding plate, the tip holding plate is easily attached to the opening of the main body by its guiding action,
The flange is deformed by its elasticity and does not hinder the mounting operation. Further, the lateral engagement between the opening of the main body and the flange of the chip holding plate resists upward pulling, and fixes the chip holding plate. A lateral force is applied to the chip holding plate, and the chip holding plate is pulled out from the opening of the main body with a guiding action of the lateral engagement. At this time, the longitudinal engagement is easily released by the elasticity of the flange, and does not hinder the pulling operation. This facilitates the work of mounting the chip holding plate, and improves work efficiency.
