2. Description of the Related Art Conventionally, when a magnetic tape used for a tape cassette for audio, video, etc. is transported between factories or internationally, it is simply cut into a product width from a raw material and cut into a length as a finished product. They are wrapped around a core called a hub, packaged, and transported or stored in their former long state.
Such a roll of long magnetic tape is usually called a pancake, and its tape width is about 4 to 15 mm, and its length varies depending on its thickness. In general, the winding diameter is about Φ300 mm. To In the hub around which the magnetic tape is wound, the inner diameter of the hole at the center of the hub is approximately Φ76 mm, and the outer diameter is approximately Φ114 mm. Then, in order to transport by normal distribution at the time of transportation or the like, various packaging forms are applied to the wound magnetic tape.

For example, as shown in FIG. 5, several windings of a magnetic tape are sandwiched between foamed cushioning materials 2 and the core 3 is inserted into hub holes and the like to be accumulated. Rigid side plates 4 are arranged on both sides of the stack, bound by a binding tool 5 such as a PP band, and stored in one or a plurality of external cardboard boxes (not shown). Packaged.
Also, as shown in FIG. 6, a foamed cushioning material 2 is adhered to the front and back sides of a tray 6 foamed and molded to a size suitable for storing the magnetic tape wound body 1, and the magnetic tape wound body 1 is placed thereon.
Is stacked for several times, and only the same tray 6 is stacked as a lid on top of it, tied with a tying tool 5 such as a PP band, and then one or more cardboard boxes for exterior use Etc. and packaged. Reference numeral 7 denotes a support formed integrally with the tray 6 that fits into the hub hole of the magnetic tape roll 1.

Further, as shown in FIG. 7, a bent portion 9 is formed at the center of one base plate 8 to divide the base plate 8 into two equal parts, and a magnetic tape winding body is provided at substantially the center of one of the sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the attached FIGS. FIG. 1 is a perspective view showing a state in which a magnetic tape winding body is arranged at a predetermined position on the inner surface of a base plate of a magnetic tape winding body packaging body to which the present invention is applied.
FIG. 4 is a developed view showing a state in which an adhesive member and a cushioning member are fixed to predetermined positions on the inner surface of the base plate, respectively. The magnetic tape roll package 16 is intended for packaging an audio pancake, and has a basic structure substantially the same as that of the conventional magnetic tape roll package 14. However, in the conventional packaging body 14 for a magnetic tape roll, the base plate 8 and the support portion 10 that fits into the hub hole of the magnetic tape roll 1 are formed as separate members.
The same member is used in the magnetic tape wound package 16. Therefore, the same reference numerals are given to the portions common to the conventional magnetic tape wound package 14, and the magnetic tape wound package 16 will be described in detail below.

The package 16 for the magnetic tape wound body also has
A rectangular base plate 8 is used.
A card board of about mm or a plastic sheet, cardboard or the like having a rigidity corresponding to the card board is adopted. If the base plate is thin, bending occurs, the magnetic tape winding body is easily deformed, and a step-down which is a poor quality of the magnetic tape winding body occurs. Further, the external force is concentrated on a part of the magnetic tape, so that the magnetic tape is easily damaged. Then, the center of the base plate 8 is formed into a bent portion 9, and the base plate 8 is divided into two by the bent portion 9, and the two side sections 17 (17 a, 17 b) are made equal.
The vicinity of the center of each section 17 is formed as a punched portion 18 (18a, 18b) for forming the support portion 10.

However, such a base plate 8 is subjected to necessary printing before punching, and a sheet-like cushioning material 2 (2a) made of polyethylene, polyurethane or the like having a thickness of about 3 mm is provided at the center of each section 17. , 2b), and an adhesive member 11 (11a,..., 11e) such as a magic tape (registered trademark) or a double-sided adhesive tape is attached to the four corners, and they are respectively fixed first. Therefore, a bending line 15 (1) is formed in the bent portion 9 of the base plate 8 by creasing.
5a, 15b) are applied in parallel, and in each punching portion 18, a part of the base plate 8 is punched into a semicircular shape having substantially the same diameter as the inner diameter of the hub 12 of the magnetic tape winding body 1, and furthermore, each semicircle Both ends of the punching line 19 (19a, 19b) having a shape are extended and punched out linearly in a length of about 2 to 4 mm.
Further, the extended opposing linear punching lines 20 (20a,
20b) and 21 (21a, 21b) on the straight line connecting both ends thereof, bending lines 22 (22a, 22b), 23 (23)
a, 23b) are applied by perforation or creasing, respectively.

Each punched portion 1 thus punched out
8 is bent at lines 22 and 23, respectively. Then, the elongated rectangular portion of each punched portion 18 stands upright on the inner surface of the base plate 8, and the semicircular portion is overlapped on the inner surface of the base plate 8 and adhered and fixed with an adhesive. Then, the both punched portions 18 integrally connected to the base plate 8 protrude from the vicinity of the center of the inner surface of each section 17 on both sides of the base plate 8 in a semi-circular shape facing each other. Therefore, both punched portions 18 fit into the hub holes of the magnetic tape roll 1 and can be used as the semicircular support portions 10 (10a, 10b) that come into contact with the inner surface thereof, and the constituent members Inexpensive package 16 for magnetic tape rolls with less cost is completed. In addition, 24 (2
4a and 24b) are window holes formed at the original positions of the punched portions 18.

The magnetic tape roll 1 is placed on the cushioning material 2a fixed to one side of the open base plate 8, for example, the inner surface of the right section 17, and the support portion 10a is fitted into the hub hole. Then, the support portion 10a
The side surface of the magnetic tape 12 fitted on the outside contacts the cushioning material 2a. Therefore, the base plate 8 is folded in two by using the bent portion 9 and overlapped, the other support portion 10b is fitted in the corresponding space in the hub hole, and the cushioning material 26 is overlaid on the other surface of the magnetic tape wound body 1. The base plate 8 is closed by bonding the corresponding bonding members 11 to each other. Then, the magnetic tape winding body 1 is sandwiched between the base plate 8 bent into two and the two cushioning members 2 receiving the adhesive force, fitted into the hub hole from the opposite direction, and provided integrally with each section 17 of the base plate 8. The magnetic tape winding body 1 can be satisfactorily supported by the supporting action by the cooperation of the two supporting portions 10. Therefore, when the package 16 is applied to the magnetic tape roll 1, the same handling as the case where the conventional package 14 is applied becomes possible.

FIG. 4 is a perspective view showing a state in which the optical disk is arranged at a predetermined position on the inner surface of the base plate of the optical disk package to which the present invention is applied. The packaging target of the optical disk package 25 is the optical disk 26, and the structure of the above-described magnetic tape roll package 16 and the package 25 are the same. The reason is that the optical disk 26 is also a recording medium, has a hub hole 27 at the center thereof, and has an external appearance similar to that of the magnetic tape wound body 1, and a similar solution is required. Therefore, the same reference numerals are given to the portions of the optical disk package 25 common to the magnetic tape roll package 16. However, the dimensions of each part are
It must be changed appropriately according to the shape, size, etc. For example, the bending portion 9 is provided with only one bending line 15. The optical disk 2 depends on the material of the base plate 8.
If there is no fear that the recording surface of No. 6 will be scratched, the buffer material 2 may not be provided.

In the above embodiment, the base plate 8 is punched into a semicircular shape to form a semicircular support portion 10 and the support portion 1
Although the contact area with the inner surface of the hub hole of No. 0 was increased to prevent rattling during transport of the magnetic tape roll or the optical disk,
Of course, the support portion can be formed by punching into another shape, for example, a semi-elliptical shape or a mountain shape. Further, in the above embodiment, the support portions 10 are formed in the respective sections on both sides of the base plate 8, but the support portions may be formed and used in only one of the sections. Further, in the above embodiment, the adhesive member 11 is applied to each of the four corners of the base plate 8 and both ends of the base plate 8 are bonded and sealed. One end may be extended and folded, and the extended portion may be inserted inside the vicinity of the other end of the base plate and sealed with a button-shaped stopper.
