Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a storage case used as a chassis or the like for storing plate-like objects such as printed circuit boards.

[Technical background of the invention]

2. Description of the Related Art Conventionally, a case having a structure as shown in FIG. 1 has been used as a case for storing a plate-like object, for example, a chassis for storing a printed circuit board.

That is, guide parts 2, 2 spaced apart in the vertical direction are attached in parallel to the inner surfaces of the left and right side plates 1a, 1a of the box-shaped chassis 1. The shape of this guide part 2 is as shown in FIG.
It has a channel shape in which a guide groove 5 opening inward of the chassis 1 is formed between the lower guide 4 and the lower guide 4. To fit the printed circuit board 6 into the chassis 1, insert both ends of the printed circuit board 6 into the guide grooves 5, 5 of the guide parts 2, 2 installed at the same height positions on the left and right side plates 1a, 1a. , I try to push it in as is.

[Problems with background technology]

A printed circuit board 6 is attached to the guide portion 2 having the shape as described above.
When inserting the guide part 2, since the end face shape of the guide part 2 is simply a channel shape, the printed circuit board 6 cannot be inserted unless it is properly aligned, resulting in extremely poor work efficiency. Also, if you force it in even though it is not properly aligned, you may damage the printed circuit board.

It is also conceivable to form an inwardly inclined tapered surface on the end surface of the guide portion 2 shown in FIG.
Although this makes it easier to insert the printed circuit board to some extent, it is not sufficient as the entrance is only slightly wider.

[Purpose of the invention] The present invention was made in order to improve the above-mentioned conventional problems, and provides a storage case that is equipped with a guide part that allows plate-like objects such as printed circuit boards to be easily inserted and that has a simple structure. The purpose is to

[Summary of the idea]

In order to achieve the above object, the storage case according to the present invention includes a guide section that is attached to the inner surfaces of the left and right side plates of the case, and includes an upper guide and a lower guide. In addition to forming a guide groove into which the side end of the upper guide is inserted, the tip of the upper guide is retracted further into the case than the tip of the lower guide. The bottom guide has a tapered or curved surface facing downward at the distal end thereof, and the lower guide width of the lower guide is larger than the upper guide width of the upper guide.

[Example of idea]

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

FIG. 3 is an enlarged perspective view of the main parts of the case according to the present invention, in which a guide section 40 attached to the case side plate 1a is shown.
An upper guide 42 and a lower guide 43 are provided to protrude inward from the upper and lower edges of the elongated guide body 41, and an opening is opened toward the case between the upper guide 42 and the lower guide 43. Guide groove 44
is formed. Then, the tip of the upper guide 42 is retracted inward from the case, that is, in the depth direction, than the tip of the lower guide 43, and the guide main body 4
1. A large receiving portion 45 is formed by the distal end of the upper guide 42 and the distal end of the lower guide 43. Furthermore, tapered surfaces 41a, 42a, and 43a that spread outward are formed at the tip of the upper guide 42, the tip of the lower guide 43, and the inner side of the guide body 41, which form the receiving portion 45, respectively. I am trying to expand it further.

Furthermore, the guide part 40 has a lower guide width 43b of the lower guide part 43 larger than an upper guide width 42b of the upper guide 42, so that it can easily receive the printed circuit board and can prevent the board from warping.

Alternatively, the tip of the upper guide 42 may be curved upward to form a curved surface to widen the receiving portion 45 for a plate-shaped object such as a printed circuit board, or the tip of the lower guide 43 may be curved downward. Furthermore, it is easy to insert printed circuit boards, etc. moreover,
The guide portion 40 may be formed in the case side plate 1a itself.

Further, the upper guide and the lower guide of the guide portion may be separate bodies.

Alternatively, the upper guide may be made to protrude both left and right from the upper edge of the guide body, and the lower guide may be made to protrude from the lower edge to both left and right, so that the center of the case 1 can also serve as a partition when the inside of the case 1 is divided into two left and right chambers. Alternatively, the intermediate portions of the upper guide and the lower guide may be omitted to save material.

[Effect of idea]

As explained above, the case related to this invention is
A plurality of guide parts are provided in parallel on side plates facing each other, and the tips of the upper guides of these guide parts are retracted further into the case than the tips of the lower guides, so that a tapered surface is formed at each tip. west,
The lower guide width of the lower guide is larger than the upper guide width of the upper guide, so when inserting a plate-shaped object such as a printed circuit board, the receiving part is large, and it is easy to check the position of the lower guide while being guided by the receiving part. Since printed circuit boards and the like can be inserted into the grooves of the guide section, they can be easily stored. Furthermore, when inserting a plate-like object, since the guide width of the lower guide is wide, it is possible to insert the plate-like object after completely placing it on the guide part, making it possible to insert the plate-like object easily and without damaging it. Can be stored,
Moreover, when multiple guide sections are provided, plate-like objects can be inserted using the wide lower guide as a guide, eliminating the possibility of inserting the object into the wrong position.The structure is also simple, and can be used as a chassis for printed circuit boards. In addition to being extremely convenient, it can also be used as a letter case, parts shelf, etc., and has many effects.

Claims (1)

[Scope of utility model registration request] By providing a plurality of guide parts spaced apart in the vertical direction on the left and right inner surfaces, and having these left and right guide parts hold the side edges of plate-like objects such as printed circuit boards, it is possible to move the plurality of plate-like objects in the vertical direction. In the case which is arranged to be stored separately, the guide part consists of an upper guide part and a lower guide, a guide groove is formed between the upper guide and the lower guide, and the tip of the upper guide is connected to the lower guide. The upper guide has a tapered surface or curved surface facing upward, and the lower guide has a tapered surface or curved surface facing downward. What is claimed is: 1. A storage case for plate-like objects, further comprising a lower guide width of the lower guide being larger than an upper guide width of the upper guide.
