Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording paper roll storage case for storing a recording paper roll in use.

[0002]

2. Description of the Related Art There is a color thermal printer which uses a recording paper roll obtained by winding a color thermal recording paper in a roll shape. There are various types of color thermal recording paper, such as those with different width dimensions, those with printing on the back for use as a postcard, and those for sticker printing. The paper rolls are used by being appropriately replaced.

The recording paper roll in use, which is taken out from the color thermal printer to replace the recording paper roll, is stored in a light-shielding bag or the like. When stored in this light-shielding bag, a tape is attached between the tip of the color thermosensitive recording paper and the outer peripheral surface of the recording paper roll, or a ring having elasticity on the outer periphery of the recording paper roll (Japanese Patent Laid-Open No. 10-203057). ) Is attached to prevent loosening.

[0004]

However, it is troublesome to attach a tape or attach a ring when the recording paper roll is stored. In addition, the tape holding the front end of the color thermosensitive recording paper may be peeled off or the ring may be removed, which may cause misalignment or looseness of the recording paper roll in the light-shielding bag.

Furthermore, since the light-shielding bag cannot protect the recording paper roll from impact or pressure, the edge portion of the recording paper roll may be damaged or a pressing mark may be generated. Further, the mouth of the light-shielding bag may be opened, the color thermosensitive recording paper may be fixed by the outside light, and the color density may be changed by the humidity.

The present invention has been made to solve the above problems, and does not require work for preventing winding looseness, and can protect a recording paper roll from impact, external light, moisture and the like. It is intended to provide a storage case for rolls.

[0007]

In order to solve the above problems, a recording paper roll storage case according to the present invention is fitted into a case body for accommodating the recording paper roll and an opening of the case body. A case lid that seals the inside of the case body, a positioning protrusion that is provided inside the case body and the case lid, and that fits into the core to position the recording paper roll, and along the radial direction of the recording paper roll. It is supposed to be movable,
And a contact member that contacts the outer peripheral surface of the recording paper roll to prevent loosening of the recording paper roll.

Further, the case body and the case lid are formed of a material having a light-shielding property and a moisture-proof property.

1 is a perspective view showing the outer appearance of a recording paper roll 2 and a storage case 3 for accommodating the recording paper roll 2. As shown in FIG. The recording paper roll 2 is formed by winding a long color thermosensitive recording paper 4 around a cylindrical core 5.

As is well known, the color thermosensitive recording paper 10 has a cyan thermosensitive coloring layer, a magenta thermosensitive coloring layer and a yellow thermosensitive coloring layer which are sequentially laminated on a support. The yellow thermosensitive coloring layer, which is the uppermost layer, has the highest heat sensitivity and develops yellow with a small amount of heat energy. The cyan thermosensitive coloring layer, which is the lowermost layer, has the lowest thermal sensitivity and develops cyan with a large amount of heat energy. The yellow thermosensitive coloring layer has a thickness of 420 nm.
When it is irradiated with the near-ultraviolet rays, the coloring ability disappears. The magenta thermosensitive coloring layer, which is the second thermosensitive coloring layer, develops magenta with heat energy in the middle of those of the yellow thermosensitive coloring layer and the cyan thermosensitive coloring layer, and loses its coloring ability when irradiated with ultraviolet rays of 365 nm. .

The storage case 3 has a cylindrical case body 7 for accommodating the recording paper roll 2 and an opening 8 in the case body 7.
