Fig. 2 is the skeleton view of expression according to the tape housing for storing cases of embodiments of the invention uncap; And

Fig. 3 is that expression is closed the skeleton view of tape housing for storing cases under the situation according to embodiments of the invention at its lid.

It below is DETAILED DESCRIPTION OF THE PREFERRED.

Embodiment of the present invention describe hereinafter with reference to the accompanying drawings.

Fig. 1 of accompanying drawing expresses the example of a plastic-backed magnetic tape box (that is, recording compact cassetter) as the tape cassete that is used for holding therein a record carrier.As shown in Figure 1, tape cassete 1 is made of fastening a pair of upper and lower tape cassete half housing 1a, 1b, and each housing is made with ABS (acrylonitrile-butadiene-styrene copolymer) resin.A pair ofly be housed in the inside of tape cassete 1 around top left and right spool wheel hub 2a, 2b, so that can freely rotate by tape T.The tape T that comes out from this wheel hub 2a, 2b exposes by the opening portion 3 of front.Wheel hub driving shaft (not shown) is inserted among patchhole 4a, the 4b of wheel hub driving shaft.The driving wheel (not shown) is inserted among patchhole 5a, the 5b of driving wheel, at patchhole 5a, 5b place near driving wheel, form the position of decision hole 6a, 6b respectively, precalculated position on the tape cassete surface, promptly, position at the upper and lower surperficial position of tape cassete 1, after wheel hub driving shaft patchhole 4a, 4b forms one and writes zone 10, the title of the musical works that can write tape T thereon and recorded or other similar content etc.In addition, sign 12 is printed on and the surface portion of writing zone 10 identical tape cassetes 1.

Fig. 2 and Fig. 3 express an example of the plastic-backed magnetic tape housing for storing cases 7 of depositing tape cassete shown in Figure 11.As shown in Figures 2 and 3, accommodation box deposit shell 7 by for example PS (polystyrene) resin make shell body 7a and lid 7b form.For this lid can freely be opened and closed with respect to shell body 7a,, will cover 7b by pivot and link to each other with shell body 7a by hinge fraction 8.Depositing in the shell 7 of accommodation box, shell body 7a and lid have at least one to manufacture with transparent material among the 7b, so that the user with the naked eye just can recognize the tape cassete 1 shell 7 deposited that is received or is stored at accommodation box from the outside.

When tape cassete 1 time spent not, just tape cassete 1 is put in the holding portion 11 of tape cassete of tape housing for storing cases 7, under the situation of closing cap 7b; this tape cassete obtains preserving; thus, the tape T that is installed in the tape cassete 1 can be protected, and avoids being made dirty by dust or analog.Precalculated position on the surface of depositing shell of accommodation box promptly, forms at the top of lid 7b and front side surface position and to write zone 10, can write the musical works that is recorded on the tape T or the similar title of content thereon.In addition, although do not draw, on the similar face of writing zone 10, can form other printing, as sign, pattern or similar item etc.

The writing zone 10 and can adopt direct printing process to form on the shell 7 of depositing of tape cassete 1 and accommodation box, as serigraphy, contaminate printing (pad printing) or similar approach etc.In the case, if use printing ink (the inorganic filler CaCO that contains coarse material that forms rough surface ₃) print and write zone 10, on this surface, can write pattern or similar content etc., can keep being equivalent to the lettering feature of paper so for oil base pen, ball pen, pencil or similar pen etc.Yet under the situation of water base pen, the water-based ink of water base pen adheres to, and its lettering feature is quite bad.When water-based ink is not dried in addition, during with the finger touch, easily darkened.Consider the diversity that is used for forming the printing-ink material of writing the zone, to also can write pattern or similar content etc. on this zone even with water base pen, be subjected to significant attention as the key component of this printing ink with the protein powder of natural collagen protein.So employing contains the surface that the printing ink of such protein powder prints tape cassete 1 and tape housing for storing cases 7 as printer's ink, form thus and write zone 10.

Be used to form the printing-ink that to write the zone, as the printing ink solvent, adopt common screen printing ink or contaminate printing-ink (macromolecular resin, as polyvinyl chloride-based resin, rubber-based resin, polyester base resin, cellulose base resin or similar resin etc. are used as bonding agent, aryl solvent, ketone-based solvent, alcohol-based solvent, ether solvent, ester group solvent or similar solvent are used to do main solvent or thinning agent, wherein also add an amount of pigment or supplement, for example titanium dioxide, lime carbonate, carbon black or analog.Secondly, contain commercially available natural collagen protein and add among this printing ink solvent an amount of as the protein powder of key component.

For containing the protein powder of natural collagen protein as key component, for example average powder size is 5 μ m, and (manufacturing of bright dipping (IDEMITSU) petro chemical industry company limited) just can calculate the SF grade.

Protein powder is original just not mixed mutually.So when protein powder was added in the printing ink solvent as mentioned above like that, protein powder can easily evenly mix in the printing ink solvent.In addition, between the powder of protein powder, can produce suitable space, so water constituent can be filled up among this space.

When the printing-ink that is containing above-mentioned protein powder is write on the zone 10 so that printing process constituted, when writing some items with water base pen, because the hydrophilic base of protein powder, can keep enough moist, the feasible water-based ink that comes out from water base is not floated.Therefore, the zone of writing of the present invention can present satisfied lettering feature and drying property to water-based ink.And even when making oil base pen, ball pen, pencil or similarly pen etc. is write, the zone of writing of the present invention can provide and in fact is equivalent to the common writing ink and the lettering feature of paper.

Be used for forming the printing-ink of writing the zone according to of the present invention, under the situation that the content of protein powder increases, lettering feature and drying property result are gratifying.From another point of view, on the print surface of tape cassete 1 and tape housing for storing cases 7, can not keep printing-ink desired such as basic physical characteristics such as adhesion strength, wearing quality, anti-scratch trace or similar characteristics.So preferable is that when the printing ink solvent was white, the content of the protein powder in printing-ink will be selected less than 30wt%, when the printing ink solvent is other printing ink, be chosen as 40wt%.When the printing ink solvent was white ink and other color ink, the appropriate content of protein powder was different, and its reason will be described hereinafter.That is exactly, and white ink is compared with other color ink more pigment, and promptly resinous principle is few.Therefore, if worsened for fear of the basic physical property of printing ink, amount of resin that need be bigger than constant, when the printing ink solvent is white ink, the content of essential compression protein matter powder.

Adopt under the situation of the printing-ink printing contain an amount of protein powder writing zone 10, can obtain satisfied writing quality and drying property.In the case, provide following method in order to improve these performances.

Printing-ink for the printing that is used to write zone 10 except protein powder above-mentioned, also can contain an amount of inorganic pigment, and its powder size is greater than the pigment granularity that contains in this pigment, or greater than the granularity of protein powder.For the inorganic pigment that big powder size is arranged, it is suitable using lime carbonate.Generally speaking, in the printing ink solvent, when the powder size of lime carbonate had 5-30 μ m big, the powder size of pigment was 1 μ m, and the powder size of protein powder is 5 μ m or less than 5 μ m.Lime carbonate is added in the printing ink solvent with protein powder.In the case, the content to protein powder and lime carbonate will be illustrated.That is exactly that when the printing ink solvent was white ink, the content of protein powder+lime carbonate was less than 40wt%.And when the printing ink solvent was other color ink, the content of protein powder+lime carbonate was less than 50wt%.

Adopting the printing-ink that also contains lime carbonate outside the isolating protein powder to print formed writing on the zone 10, the pigment in the powder size of lime carbonate and the above-mentioned printing ink solvent or the granulometric facies of protein powder relatively are big.So, on the surface of the printing-ink that prints, produce suitable space.Therefore, when writing with water base pen when writing some item on the zone 10, the water-based ink of water base pen is infiltrated in this space, obtains higher lettering feature and higher drying property thus.In addition, write on the zone 10 at this, because lime carbonate makes rough surface, so that the anti-scratch trace that is reached when writing some thing with pen improves.That is to say, write, further improved the performance of writing thus with suitable anti-scratch trace performance.

For the inorganic pigment of its powder size, except that lime carbonate, also can utilize zinc paste, zinc carbonate, aluminium oxide, alumina silicate, barium sulphate or analog greater than the protein powder granularity.And, form the tape cassete 1 of printing zone and tape cassete case 7 thereon and be not limited to cited those of embodiment, and similarly can be applied to by all plastics ABS for example PS, the depositing on the shell 7 of tape cassete 1 that PP or similar material etc. makes and accommodation box.

As mentioned above, according to the shell of depositing of record carrier accommodation box of the present invention and accommodation box, because formation thereon can be write the zone and can be obtained following effect.

Owing to be different from prior art, do not use label made of paper, such write zone even can write the zone in changes in environmental conditions or with the finger scratching, is avoided being torn off.When writing the zone little the time, it is obvious especially that such effect just seems.

Forms with printing owing to writing the zone, just can form the zone of writing of composite structure that common label do not accomplish.

Because the present invention does not utilize the paper source, the present invention can make contributions to earth environment protection.

Can be formed by a kind of typography simultaneously with other printing (sign and such as the design of similar pattern) owing to can write the zone, this just causes the reduction of expense.In addition, in the manufacture process of tape cassete, the operation that label is inserted that also need not be common, so that the substandard products percent of product can obtain descending.

In addition, can write the zone, no longer need the required catalogue card of common tape housing for storing cases owing on the tape housing for storing cases, forming with typography.Therefore, the depositing shell and can be miniaturized of accommodation box, and can prevent that the recorded information of being write from being lost.

Although as the description to aforementioned record carrier accommodation box, the record carrier accommodation box is not limited to tape cassete with the description of tape cassete (recording compact cassetter), also be applicable to disk cartridge or similar box.

In addition,, the invention is not restricted to this, can write the zone and also can form at the inside surface of depositing shell of accommodation box though can write on the outside surface of depositing shell that the zone is formed in aforesaid accommodation box.

With reference to description of drawings the preferred embodiments of the present invention, be appreciated that the present invention is not limited to those preferred embodiments, those skilled in the art, under the situation that does not break away from the appended invention spirit and scope that claim limited, can also realize various variations and remodeling.
