Although not shown in the drawing, a label sticker can be attached to the lower surface (lower cassette shell 1b) of the tape cassette 1 in the same manner. In addition, the attachment part of the label seal 100 in the cassette shell is formed in a concave shape in advance.

The label seal 100 has a luminous property, on which title characters and the like can be freely written.

In the tape cassette 1 to which the label seal 100 is attached, when the periphery becomes dark, the label seal 100 shines in the dark as shown in FIG. 2, and the letter a such as a title written on the label cassette 100 emerges. Become. Therefore, a desired tape cassette can be easily found even at night.

FIG. 3 shows a cassette storage case for storing the tape cassette 1. The cassette storage case 10 is composed of a case main body 11 made of, for example, PS (polystyrene) and a lid 12. The lid 12 is pivotally attached to the case main body 11 via a shaft fulcrum 13 so as to be able to open and close. Are linked. When the tape cassette 1 is not used, the tape cassette 1 is exposed in the front opening 3 of the tape cassette 1 by storing the tape cassette 1 in the accommodating portion 11a of the case body 11 with the lid 12 closed. The magnetic tape T is protected from dust and the like.

In the cassette storage case 10, both the case body 11 and the lid 12 are formed transparent so that the tape cassette 1 stored therein can be visually recognized from the outside. Reference numeral 14 denotes an index card (a card for writing titles, music pieces, and the like) inserted into the cassette storage case 10 together with the tape cassette 1.

A label sticker 100 having a light-emitting property is attached to a predetermined portion of the surface of the cassette storage case 10, that is, the upper surface and the rear surface of the lid 12 in this embodiment.

Also in the cassette storage case 10 to which the label seal 100 is attached, when the surroundings become dark, the label seal 100 shines in the dark as shown in FIG. 4, and the letter a such as a title written thereon appears. Since it is raised, it is possible to easily find a desired tape cassette even at night.

An embodiment of the label sticker 100 to be attached to the tape cassette 1 and the cassette storage case 10 will be described in detail with reference to FIG.

FIG. 5 is a plan view showing the entire label seal 100, and FIG. 6 is a sectional view thereof.

In FIG. 1, reference numeral 101 denotes a seal board. The seal board 101 is formed of a paper material or a resin sheet, and has a seal surface coated with an adhesive on the back surface (lower surface).
On this sealing surface, the tape cassette 1 and the cassette storage case 10 can be attached. The color of the sticker sheet 101 is white in order to obtain a high reflectance.

Then, luminous ink is printed on a part of the surface of the seal board 101 to form a luminous portion 102 such as a line or a character as shown in FIG.

The luminous ink used for printing the luminous light emitting portion 102 is a general printing ink based on an ink, which is mixed with a luminous material.

As the luminous material, a high-luminance luminous material which emits light for a long time by storing light for a short time is suitable, and a long afterglow phosphor "N night light" (Nemoto Special Chemical ).

This is a material obtained by mixing high-purity alumina as a raw material, mixing rare earth elements and sintering at about 1300 ° C.
It is a luminous material that maintains the luminance of the light emission level that can be visually recognized for more than 8 hours with one light storage. Further, since this material does not contain a radioactive substance, it can be used safely from the viewpoint of environmental protection.

As a printing method of the luminous ink, silk screen printing is preferable in order to increase the printing thickness, and the printing thickness is optimally about 0.1 mm.

Although the luminous ink is more expensive than the general ink, the luminous light emitting portion 102 is provided on a part of the surface of the seal board 101 in this example, so that the amount of the luminous ink used is small. Printing at low cost.

FIG. 7 shows an example in which the surface of the seal mount 101 is entirely covered with the resin film 103 including the luminous portion 102.

The resin film 103 is made of acrylic or PE
It is made of a material having good translucency, such as T (polyethylene terephthalate), and has a thickness of about 10 μm or more.

The surface of the resin film 103 is subjected to a matting process having fine irregularities of about several μm. By this matting process, the resin film 103
Surface can be made writable, that is, an oil-based pen,
Writing with any writing implement such as a water-based pen, a ball-point pen, and a pencil becomes possible.

Instead of this matting process, an ink having a so-called writing property may be applied to the surface of the resin film 103.

As the ink having the writability, an acrylic ink or the like having good translucency containing calcium carbonate or various protein fine particles (protein powder) is used. In other words, by including calcium carbonate in the ink, the surface to which the ink is applied is formed into a moderately rough surface, so that it is possible to write here with an oil-based pen, a ballpoint pen, a pencil, etc., in the same manner as paper, By including the protein microparticles, the hydrophilic group of the protein microparticles enables good writing to be obtained even with an aqueous pen without the aqueous ink floating.

FIG. 8 shows the principle of reflection in the example of FIG. In the dark, the light emitted from the night light emitting unit 102 is radiated to the surroundings, and a part of the light is reflected by the white seal mount 101 having a high reflectance. Thereby, the entire label seal 100 shines efficiently. Therefore, even if the luminous intensity of the luminous light emitting unit 102 is small, the character a written on the surface of the resin film 103 clearly emerges in the dark and becomes visible.

Further, since the resin film 103 is made of a material having good translucency, the entire label seal 100 is efficiently illuminated even by light propagating inside the resin film 103, and the character a is clearly visible. Becomes

Further, the character a can be visually recognized by illuminating the character a with the light that directly reaches from the night light emitting unit 102.

FIG. 9 shows an example in which the resin film 103 has a two-layer structure. That is, in this example, the resin film 103
Has a two-layer structure consisting of an upper film 103A and a lower film 103B.

Each of the upper film 103A and the lower film 103B is made of a material having good translucency such as acrylic or PET, and has a thickness of about 10 μm or more.

The surface of the upper film 103A of the resin film 103 is subjected to a matting process having fine irregularities of about several μm, and the matting process allows the surface of the upper film 103A to be written. You can have.

Instead of this matting process, an ink having so-called writability (described above) may be applied to the surface of the upper film 103A.

On the other hand, the upper surface of the lower film 103B, that is, the bonding surface with the upper film 103A, is provided with a coating 104 having a high reflectance in order to efficiently reflect light. That is, the resin film 103 of this example has the coating layer 104 with high reflectance between the upper film 103A and the lower film 103B.

FIG. 10 shows the reflection principle in the example of FIG. The light emitted from the luminous light emitting part 102 in the dark and reflected by the white seal board 101 is transmitted through the two-layer resin film 103 as it is, and the inside of the lower film 103B has a high reflectance. The light is split into light that spreads while repeating multiple reflections between the coating layer 104 and the white seal mount 101.

The light that spreads while repeating the multiple reflections ensures a sufficient amount of light even at a position distant from the night light emitting section 102, and the entire label seal 100 can be made to emit light more efficiently.
Even if the light emission amount of No. 2 is small, the letter a written on the surface of the upper layer film 103A clearly emerges in the dark and becomes visible.

In the above embodiment, the seal board 10
Although the case where the surface of No. 1 is covered with a resin film 103 having good translucency is shown, as a method of covering the surface of the seal board 101, an acrylic ink or the like having good translucency other than the resin film 103 is used. May be used. In this case, a so-called writable ink (described above) is used as the ink, and the ink is printed on the surface of the seal board 101.

When the surface of the seal board 101 is covered with the ink having good translucency and writing properties as described above,
Almost the same effects as in the example shown in FIG. 7 can be obtained.

11 and 12 show another example of the shape of the night light emitting portion 102 of the label seal 100. FIG. 11 shows a case where the night light emitting portion 102 is formed in a frame shape, and FIG. This is a case where two lines are formed in parallel. By forming the luminous light emitting portion 102 in such a shape, the entire label seal 100 can be illuminated widely and uniformly, so that the visibility effect in the dark can be further enhanced.

[0048]

As is clear from the above description, by attaching the label seal of the present invention to a tape cassette or the like, the visibility in the dark is improved, and the handling becomes easy. The label seal of the present invention can be provided at low cost and inexpensive because the amount of luminous ink used can be reduced by providing the luminous light emitting part on a part of the seal mount. By making the color of the seal mount white and covering the surface of the seal mount with a resin film, etc., the entire label seal can be illuminated efficiently even with a small amount of light emitted from the luminous light emitting part, so that the visual effect in the dark is sufficient. Is secured. Further, in the present invention, there is also an effect of protecting the luminous light emitting portion by covering the surface of the seal mount with a resin film or the like.
