Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a container for magnetic tape cassettes in which a plurality of main body parts such as cassette halves and guard panels of magnetic tape cassettes are housed and transported side by side.

(Prior Art) For example, the upper and lower cassette halves of a magnetic tape cassette are manufactured during the manufacturing process of video tape cassettes.
For example, a large quantity of cassettes may be transported from the cassette half manufacturing department to the cassette assembly department. Conventionally, the container for transporting the cassette halves in such cases has been a foamed resin container or cardboard which can tightly accommodate the cassette halves. However, with the above-mentioned foamed resin container, it is difficult to finish the space for accommodating the cassette halves to highly accurate dimensions, and since the dimensions of this space change over time, it may be difficult to insert and remove the cassette halves. Furthermore, the surface of the cassette half was often scratched by the wall surface of the container during transportation and loading/unloading operations.

In particular, if the cassette half of a video cassette has the above-mentioned scratches on the face of the product, it has become a problem because the product value is almost completely lost.

On the other hand, when using a cardboard box, paper or the like is placed between adjacent cassette halves to prevent the large number of cassette halves packed together into the cardboard box from rubbing against each other and causing damage. This increases the number of man-hours required for loading and unloading cassette halves. In this case, it becomes extremely difficult to automate the work of loading and unloading the cassette halves.

The present invention was devised to solve these problems, and provides a container for magnetic tape cassettes in which cassette halves can always be taken in and out easily, and there is no risk of the surface of the cassette halves being scratched by the container walls. The purpose is to provide

(Means for Solving the Problems) The container for magnetic tape cassettes of the present invention is a container for storing and transporting a plurality of angular main body parts such as cassette halves and guard panels side by side. a bottom wall covering the bottom of the
It consists of a pair of opposing side walls rising upward from the bottom wall on both sides of the side-by-side parts, and the intersection of the bottom wall and both side walls is in line contact with the ridgeline of the lower side edge of the part. It is characterized by being formed into a curved shape that supports the component.

(Function) When a component such as a cassette half is placed in the magnetic tape cassette container configured as described above, this component has a curved shape, and the lower side edge of the component is located at the intersection of the container bottom wall and both side walls. They are supported by this intersection in line contact. Therefore, even if the above-mentioned parts move slightly due to vibration when they are stored in a container and transported, the side and bottom surfaces of the parts are not in surface contact with the side walls and bottom walls of the container, so that the surface of the parts will not be affected. There is little risk of scratches. Further, the intersection portion is formed in the above-mentioned curved shape, for example, a rounded shape, and a gap is formed between the container side wall and the side surface of the component and between the container bottom wall and the bottom surface of the component. Therefore, it is extremely easy to take the component in and out of the container, and there is no risk of the surface of the component rubbing against the wall surface of the container and causing scratches when taking it in and out of the container.

(Example) An example of the present invention will be described below with reference to the drawings.

1 and 2 show a part of a magnetic tape cassette container according to an embodiment of the present invention, which is mainly used for storing and transporting both upper and lower cassette halves 1 of a video cassette. This container is formed into a substantially box-like shape by a front wall 2, a rear wall 3, left and right side walls 4, 5, and a bottom wall 6 made of non-foaming material such as acrylic resin, and is spaced at equal intervals between the left and right side walls 4, 5. The interior is divided into a plurality of accommodating portions 8 by a plurality of central side walls 7 arranged therein. Also, in each housing section 8, the housed cassette half 1
A plurality of pairs of ribs 9 are formed to extend vertically from the side walls 4, 5, and 7.

FIG. 3 shows a part of the cross-sectional view taken along the line A-A in FIG. This tape cassette 1 is shown arranged so that the lower side edges of the tape cassette 1 are in contact with each other. That is,
The tape cassette 1 comes into contact with the container wall only at both lower side edges, so even if the tape cassette 1 is subjected to some vibration during container transportation, the upper side edges will not slide up or down along the curved surface of the intersection. Since the cassette half 1 only slides down and comes into contact with the wall of the container only at the lower side edge, the relationship between the side and bottom walls of the cassette half 1 and the container wall remains the same, causing scratches due to the side and bottom walls of the cassette half 1 rubbing against the container wall. There is no. Further, the side wall of the tape cassette 1 housed in the container and the container side walls 4 and 5 are set to have a predetermined angle α (for example, about 3 degrees), and the bottom wall of the tape cassette 1 and the bottom wall of the container 6 is set to have a predetermined angle β (for example, about 5 degrees), so that even if the lower side edge of the tape cassette 1 moves to some extent along the curved surface 10 of the container, the wall surface of the tape cassette 1 will be aligned with the container wall surface. 4, 5, 6, and 7 are designed to avoid scratches caused by rubbing against each other. The radius of curvature R of the curved surface 10 is, for example, approximately 12 mm.

FIG. 4 is a partially enlarged plan view showing the rib 9 shown in FIG. 1. FIG. This rib 9 is designed such that both its front and rear wall surfaces have an inclination such that the thickness of the rib becomes thinner as it goes toward the tip of the rib (toward the center of each housing), and the cross section is arranged along the center line of the rib. It is formed so as to have line symmetry with respect to. The angle γ formed between both wall surfaces and the center line 11 is set to, for example, about 2°. As a result, the tape cassette 1 housed in the container comes into line contact with the wall surface of the rib 9 at the side edges of the front and rear walls, and the front and rear wall surfaces of the tape cassette 1 come into surface contact with both the front and rear wall surfaces of the rib 9. It is possible to prevent a situation where the parts are scratched by rubbing against each other.

In addition, the side walls 4, 5, 7 and the bottom wall 6 of the container
Since the above-mentioned R is provided at the intersection of the tape cassette half and the rib 9 is formed into the above-mentioned tapered shape, the lateral and front-back dimensions of the accommodating section 8 are equal to the dimensions of the tape cassette half. There is no need to take this into account and set the settings so strictly, making it easier to manufacture the container.

In addition, although the above-mentioned embodiment accommodates both the upper and lower tape cassette halves 1 which are combined, the parts to be accommodated are not limited to this, and either one of the upper or lower tape cassette halves or the guard panel may be accommodated. It is possible to accommodate various parts of the angular main body, such as (or a lid). However, if the guard panel is housed in a container with its top facing upward, only the wall surface of the rib 9 facing the front surface of the guard panel may be tilted in the same way as the rib 9 in the above-described embodiment, and the guard panel The wall surface of the rib 9 on the side not facing the front surface does not need to be particularly inclined. In this case, the radius of curvature R of the curved surface 10 at the intersection of the side walls 4, 5, 7 and the bottom wall 6 of the container may be set to an appropriate value depending on the size of the guard panel, for example, 10 mm. Further, in this case, the angles formed between the container side walls 4, 5, 7 and the side wall of the guard panel, and between the container bottom wall 6 and the bottom wall of the guard panel are each about 5 degrees, for example.

In addition, if an opening extending from the front wall 2 to the rear wall 3 is provided in the center part of the bottom wall 6 in each accommodating part 8, the housing in one accommodating part 8 can be made by inserting a protrusion jig through this opening. Since it is possible to simultaneously and smoothly take out all the parts such as the cassette halves that have been placed, the parts can be taken out at high speed automatically and can be taken out without damaging the surfaces of the parts.

Further, the members forming the bottom wall 6, side walls 4, 5, 7, ribs 9, etc. are not limited to those of the above-mentioned embodiments, but may be formed of various other members such as plastic resin. However, it is preferable to use a soft material that does not easily damage the surface of the guard panel when it rubs against the surface of the guard panel, and it is more preferable to use a material whose hardness is lower than that of the guard panel forming member.

Note that the curved shape of the intersection of the bottom wall 6 and the side walls 4, 5, and 7 does not necessarily have to be the above-mentioned cylindrical shape. Various curved shapes capable of supporting the component are possible.

(Effects of the invention) According to the magnetic tape cassette container of the present invention, as described above, the intersection of the bottom wall and both side walls constituting the container has a predetermined curved shape, and the lower side edge of the accommodated part This housing component is supported only by the ridgeline to prevent the wall surface of this component from coming into surface contact with the wall surface of the container, which will cause scratches on the wall surface of the component when transporting the container or loading and unloading the component into the container. There is no fear.
