Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a plate attachment part provided in an equipment case.

For example, in an electronic device such as an electronic cash register, a plate indicating the manufacturer, model name, model number, etc. is attached to the device case. Normally, in order to attach a plate to an equipment case, the plate is attached to a recess formed on the outer surface of the equipment case using adhesive or adhesive tape.

Generally, device cases are made of synthetic resin, and when the device case is formed using a mold, recesses for attaching the case are formed in each case.
A conventional case pasting recess has the form shown in FIG. In this case, a recess 2 whose periphery is closed is formed in a vertical wall 1 of the case in accordance with the shape and size of the plate 3. In this form, when the recess 2 is formed by directly forming the convex part for forming the recess in the mold for forming the case, the protrusion fits into the recess 2 when the mold is removed, and the mold is divided into parts, for example, in the vertical direction and opened. Therefore, it is necessary to specially provide a recess-forming slide core in the mold to enable the mold to be removed, which complicates the mold structure and significantly increases the mold cost. In addition, as another form, the second
As shown in the figure, there is a case in which a recess 5 is formed in an inclined wall 4 of the case. In this form, since the wall portion is inclined, even if the recess 5 is formed directly with the mold, the mold can be opened by dividing it into upper and lower parts, for example, and the mold structure is simple. It is necessary to widen the upper side of the recess 5 along the mold cutting direction to prevent an undercut when opening vertically. For this reason, the gap between the upper side of the recess 5 and the plate 3 attached here becomes wide, and dust accumulates in this gap, contaminating the plate 3, and also inserts fingernails etc. into the gap. There is a drawback that 3 can be easily peeled off.

By the way, in an equipment case, due to structural and assembly problems such as making it possible to store or take out each part provided inside the case, the case is divided into at least two case bodies in the vertical or horizontal direction. These case bodies are joined together to form a case.

The present invention was developed in view of the above circumstances, and it is an equipment case that solves the conventional problem with the mold and recess shape by providing a plate attachment recess using the two case bodies that make up the equipment case. This provides the structure of the plate attachment part.

Embodiments of the present invention will be described below with reference to drawings.

3 to 5 show an embodiment of the present invention, and FIG. 3 shows a case of an electronic cash register as an example of a device case provided with the plate attachment part of the present invention. FIGS. 4 and 5 are enlarged views of the plate mounting portion. In the figure, 11 is an equipment case, and this equipment case 1
Reference numeral 1 indicates an upper case 12 (one case body) made of synthetic resin for forming the upper part, and a lower case 13 made of synthetic resin for forming the lower part.
(the other case body).
The front part of the upper case 12 is an operation panel 14 having a keyboard and a display part, and the rear part and both sides are walls 12a extending in the vertical direction, and the lower part is open. Lower case 13
The peripheral wall is a rising wall portion 13a, and the upper portion is open. The edge surface of the lower open part of the upper case 12, that is, the joint end surface 12b, and the lower case 1
The edge surfaces of the upper open parts of 3, that is, the joint end surfaces 13b are abutted against each other, and the two joint end surfaces 12b and 13b are tightened and fixed with a screw member (not shown) to join and fix both cases 12 and 13. . In addition, 18 in the figure
is Droa.

The plate attachment portions are provided at the rear of the device case 11, that is, at the rear of the wall 12a of the upper case 12 and at the rear of the wall 13a of the lower case 13.
A rectangular case attachment recess 15 is formed in the lower part of the outer surface of the wall portion 12a at the rear of the upper case 12 in accordance with the shape of the plate 17 to be attached. In addition, it has dimensions slightly larger than the plate 17 so that there is a small gap between the periphery of the recess 15 and the periphery of the plate 17 so that a fingernail or the like cannot be inserted. The upper side and both sides of the recessed part 15 are formed by the wall part 12a and are closed. Recess 1
The lower side of 5 coincides with a straight joint end surface 12b of the lower open portion of the upper case 12, and is opened at this joint end surface 12b to form an open end 15a. That is, the recess 15 is located in the upper case 1.
Joint end surface 1 that joins with the lower case 13 in 2
It was opened in 2b. The depth of the recess 15 is preferably larger than the sum of the thickness of the plate 17 and the adhesive or adhesive tape to which it is attached, and in this embodiment, the upper case 12 is formed. As a draft for extracting the mold (lower mold), the bottom surface of the recess 15 is inclined so that the depth increases toward the open end 15a. In addition, the wall portion 1 at the rear of the lower case 13
A rib 16 is formed on the joint end surface 13b of the upper case 12 to protrude outward at a location opposite to the open end 15a of the recess 15 in the upper case 12. The rib 16 has a length and width corresponding to the length and depth of the open end 15a, and closes the entire open end 15a of the recess 15. That is, the open end 15a of the recess 15 is closed by the joint end surface 13b of the lower case 13. Therefore, the open end 15a of the recess 15 is closed by the rib 16 of the lower case 13, that is, the joint end surface 13b, so that the recess 15 is surrounded and becomes a closed recess. The plate 17 is, for example, in the shape of a rectangular plate, and the manufacturer, model name, model number, etc. of the registered machine are written on its outer surface. The plate 17 is fitted into the recess 15 and attached with adhesive, adhesive tape, or the like. For this reason,
The plate 17 is surrounded on three sides by the upper side and both sides of the recess 15, and surrounded on one side by a rib 16, that is, the rib 16 of the joint end surface 13b, when attached.

A case in which the upper case 12 having the recess 15 is formed using a mold will now be described. The mold for forming the upper case 12 is composed of an upper mold and a lower mold. The upper mold forms the upper part of the wall 12a that does not include the recess 15 of the upper case 12, and the lower mold forms the lower part of the wall 12a that includes the recess 15. It has a convex portion having a shape corresponding to 15. . The joining line where the upper die and the lower die are joined to each other is located at a location corresponding to the upper side of the recess 15 or at a location higher than that. Then, when the upper mold and the lower mold are combined and the upper case 12, that is, the wall portion 12a is formed of synthetic resin, the wall portion 12a and the recessed portion 15 are formed. When cutting the mold, both molds are opened up and down, and the upper mold is pulled upward to be removed, and the lower mold is pulled downward to be removed. In other words, the upper mold and the lower mold are opened along the direction perpendicular to the open end 15a of the recess 15, that is, the joint end surfaces 12b and 13b of the cases 12 and 13, and are extracted. In this case, since the convex part forming the concave part 15 in the lower mold has a shape in which the concave part 15 has an open lower side, this open part 15a serves as an outlet for extracting the convex part. Therefore, when the lower die is extracted downward, the convex portion can also be extracted downward from the open end 15a of the recess 15, and the lower die having the convex portion can also be extracted. In this way, the mold directly creates the recess 1.
5, it is possible to divide the mold into upper and lower parts, open the mold, and extract the mold. Therefore, there is no need to use a conventional slide core or the like in the mold to form the recess 15, and the recess 15 can be formed directly with the mold, so the structure of the mold is simple and the mold Cost is low. Moreover, the upper mold and the lower mold are pulled out in the same direction as the wall 12a while being moved in parallel along the wall 12a, and the convex part of the lower mold is also removed from the wall 12a.
It can be extracted by moving in the same direction as a, and the convex portion of the lower mold is extracted from the open end 15a of the recess 15. Therefore, in order to extract the protrusion of the lower mold from the recess 15, there is no need to incline and widen the upper and lower sides of the recess 15 outward. Therefore, the gap between the plate 17 and the upper side and both sides of the recess 15 surrounding the plate 17 can be made small, and it is possible to prevent the plate 17 from becoming dirty due to dust adhering to and accumulating in this gap. It becomes impossible to peel off the plate 17 by inserting a fingernail into the plate 17.

Furthermore, FIG. 6 shows the joint end surface 1 of the lower case 13.
Open end 1 of recess 15 formed in upper case 12 with only joint end surface 13b without forming rib 16 on 3b
A configuration in which 5a is closed is shown.

It should be noted that the case body that constitutes the equipment case may be joined to the left and right sides instead of the top and bottom; in this case, a recess that opens at the joint end is formed in either the left or right case body, and the other case body is joined to the left and right sides. Close the open end of the recess at the joint end of the body. The case bodies used are those that constitute the equipment case and are joined together. The size and shape of the recess may be set according to the size and shape of the plate, and the location where it is formed may be on the side or front of the device case. The shape of the joint end surface of the other case body that closes the open end of the recessed portion is not limited to that in the embodiment, and any shape may be used as long as it is a joint end surface with one case body. The opening direction of the mold forming one case body may be the left-right direction depending on the position of the recess.

As explained above, the structure of the plate attachment part of the device case of the present invention is such that a plate attachment recess is formed in one case body that is open at the joint end surface thereof, and the open end of the recess is closed by the joint end surface of the other case body. Therefore, a slide core etc. is not used to form the case body, the structure of the mold is simple and mold costs can be reduced, and the gap between the recess and the plate is small. The plate cannot be easily peeled off with a fingernail or the like, and the plate is not stained.
