Description

本発明は、埃の掻き出し、捕集に好適に用いられる清掃用物品に関する。   The present invention relates to a cleaning article that is suitably used for scraping and collecting dust.

一方向に延びる繊維束を用いた清掃用物品が知られている。例えば、熱溶着性シートと該シートに接合して一方向に延びる多数の熱溶着性長繊維とからなる使い捨て拭き取り用具が提案されている(特許文献1参照)。この拭き取り用具においては、長繊維が、該長繊維と交叉する方向に延び、該長繊維の長手方向に間欠的に配設された複数の溶着線によって前記シートに接合している。   Cleaning articles using fiber bundles extending in one direction are known. For example, a disposable wiping tool composed of a heat-weldable sheet and a large number of heat-weldable long fibers bonded to the sheet and extending in one direction has been proposed (see Patent Document 1). In this wiping tool, the long fibers extend in a direction intersecting with the long fibers, and are joined to the sheet by a plurality of welding wires arranged intermittently in the longitudinal direction of the long fibers.

また、刷毛部が、軟質なシートで細長く形成された複数の短冊片と、繊維束とで形成されている清掃用物品が提案されている(特許文献2参照)。 短冊片と繊維束とは、複数の短冊片を有する少なくとも1枚のシートと、少なくとも1層の繊維束とが重ねられて部分的に接合されている。   Further, there has been proposed a cleaning article in which a brush portion is formed of a plurality of strips formed of a soft sheet and elongated and a fiber bundle (see Patent Document 2). The strip piece and the fiber bundle are partially joined by overlapping at least one sheet having a plurality of strip pieces and at least one layer of fiber bundle.

これらの清掃用物品においては、繊維間に埃を捕捉して保持するという機構で清掃が行われる。太さにもよるが、繊維は通常剛性が低い(コシが弱い)ので、これらの清掃用物品を用いて隅部に溜まった埃を除去しようとしても、繊維が屈曲してしまい隅部まで行き届かず、満足すべき清掃効果が得られない。清掃対象面にこびりついたゴミを除去することも困難である。   In these cleaning articles, cleaning is performed by a mechanism that captures and holds dust between fibers. Depending on the thickness, the fiber is usually low in rigidity (weak stiffness), so even if you try to remove dust collected in the corner using these cleaning articles, the fiber will bend and go to the corner. It does not reach, and satisfactory cleaning effect cannot be obtained. It is also difficult to remove dust stuck to the surface to be cleaned.

従って本発明の目的は、前述した従来技術が有する欠点を解消し得る清掃用物品を提供することにある。   Accordingly, an object of the present invention is to provide a cleaning article that can eliminate the drawbacks of the prior art described above.

本発明は、繊維層と縦長の掻き出し用シートとを備え、
繊維層と掻き出し用シートとは、繊維層における繊維の配向方向が、掻き出し用シートの長手方向と略直交するように積層され、且つ掻き出し用シートの長手方向にわたり接合されており、
掻き出し用シートとしてバルクソフトネスの最大荷重値が0.2〜4.0N/mmのものを用いた清掃用物品を提供することにより前記目的を達成したものである。
The present invention comprises a fiber layer and a vertically long scraping sheet,
The fiber layer and the scraping sheet are laminated so that the orientation direction of the fibers in the fiber layer is substantially orthogonal to the longitudinal direction of the scraping sheet, and are bonded over the longitudinal direction of the scraping sheet,
The object is achieved by providing a cleaning article using a scraping sheet having a maximum load value of bulk softness of 0.2 to 4.0 N / mm.

本発明によれば、特定のバルクソフトネス値を有する掻き取り用シートの作用によって、隅部に溜まった埃が容易に掻き出され、また清掃対象面にこびりついたゴミが容易に掻き取られ、繊維束からなる繊維層に絡み取られる。   According to the present invention, due to the action of the scraping sheet having a specific bulk softness value, dust accumulated in the corners is easily scraped, and dust stuck to the surface to be cleaned is easily scraped off. It is entangled in a fiber layer composed of fiber bundles.

以下本発明を、その好ましい実施形態に基づき図面を参照しながら説明する。図1には、本発明の清掃用物品の一実施形態が示されている。図2は、図1に示す清掃用物品の分解斜視図である。図1及び図2に示す清掃用物品10は全体として縦長で扁平な形状を有するものである。清掃用物品10は4層の繊維層11a,11b,11c,11dを備えている。また清掃用物品10は2枚の掻き出し用シート12,a,12bを備えている。   The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows an embodiment of the cleaning article of the present invention. FIG. 2 is an exploded perspective view of the cleaning article shown in FIG. The cleaning article 10 shown in FIGS. 1 and 2 has a vertically long and flat shape as a whole. The cleaning article 10 includes four fiber layers 11a, 11b, 11c, and 11d. The cleaning article 10 includes two scraping sheets 12, a and 12b.

繊維層は、所定の厚みをもって繊維束が配向されてなるものである。繊維束は、清掃用物品10の幅方向に配向している。   The fiber layer is formed by aligning fiber bundles with a predetermined thickness. The fiber bundle is oriented in the width direction of the cleaning article 10.

隣り合う繊維層である繊維層11aと繊維層11bとの間には、縦長矩形の掻き出し用シート12aが配されている。同様に繊維層11cと繊維層11dとの間には、縦長矩形の掻き出し用シート12bが配されている。2枚の掻き出し用シート12a,12bは同形をしている。また2枚の掻き出し用シート12a,12bはそれらの長手方向が、清掃用物品10の長手方向と一致している。更に、2枚の掻き出し用シート12a,12bは、それらの幅が、繊維層11a〜11dを構成する繊維の長さよりも短くなっている。   Between the fiber layer 11a and the fiber layer 11b which are adjacent fiber layers, a vertically long rectangular scraping sheet 12a is disposed. Similarly, a vertically long rectangular scraping sheet 12b is disposed between the fiber layer 11c and the fiber layer 11d. The two scraping sheets 12a and 12b have the same shape. Further, the longitudinal direction of the two scraping sheets 12 a and 12 b coincides with the longitudinal direction of the cleaning article 10. Further, the two scraping sheets 12a and 12b have a width shorter than the length of the fibers constituting the fiber layers 11a to 11d.

繊維層11bと繊維層11cとの間には、何れも矩形である把手装着用シート13a,13bが配されている。把手装着用シート13a,13bは、それらの長さが掻き出し用シート12a,12bの長さとほぼ同じになっている。しかし、把手装着用シート13a,13bの幅は、掻き出し用シート12a,12bの幅よりも狭くなっている。   Between the fiber layer 11b and the fiber layer 11c, handle mounting sheets 13a and 13b, both of which are rectangular, are arranged. The lengths of the handle mounting sheets 13a and 13b are substantially the same as the lengths of the scraping sheets 12a and 12b. However, the width of the grip mounting sheets 13a and 13b is narrower than the width of the scraping sheets 12a and 12b.

各繊維層11a〜11dと、各掻き出し用シート12a,12bと、各把手装着用シート13a,13bとは、各繊維層11a〜11dにおける繊維の配向方向が、掻き出し用シート12a,12b及び把手装着用シート13a,13bの長手方向と略直交するように積層されている。更に繊維層、掻き出し用シート及び把手装着用シートは、それらの幅方向中央部を一致させて、掻き出し用シート及び把手装着用シートの長手方向にわたり接合されている。接合は、所定幅をもった直線状の接合ライン14に沿って行われる。接合ライン14は、繊維層、掻き出し用シート及び把手装着用シートの幅方向中央部に形成される。接合ラインは、例えば熱融着、接着剤による接着などの公知の接合手段によって形成される。繊維層、掻き出し用シート及び把手装着用シートの何れもが熱融着性の材料から構成されている場合には、熱融着によって接合ライン14を形成することが簡便である。   Each of the fiber layers 11a to 11d, each of the scraping sheets 12a and 12b, and each of the handle mounting sheets 13a and 13b has a fiber orientation direction in each of the fiber layers 11a to 11d, and the scraping sheets 12a and 12b and the handle mounting. The sheets 13a and 13b are laminated so as to be substantially orthogonal to the longitudinal direction. Further, the fiber layer, the scraping sheet, and the handle mounting sheet are joined to each other in the longitudinal direction of the scraping sheet and the handle mounting sheet with their width direction center portions aligned. The joining is performed along a linear joining line 14 having a predetermined width. The joining line 14 is formed in the center in the width direction of the fiber layer, the scraping sheet, and the handle mounting sheet. A joining line is formed by well-known joining means, such as heat sealing | fusion and adhesion | attachment by an adhesive agent, for example. When all of the fiber layer, the scraping sheet, and the handle mounting sheet are made of a heat-fusible material, it is easy to form the joining line 14 by heat-sealing.

前記の接合ライン14による接合の他に、把手装着用シート13a,13bにおいては、それらの左右両側部も接合される。つまり把手装着用シート13a,13bにおいては、それらの幅方向中央部が、長手方向に沿って直線状に接合されると共に、それらの左右両側部が、長手方向に沿って直線状に接合される。その結果、これら2枚の把手装着用シート13a,13bによって、清掃用物品10の長手方向に延びる筒状の空間15が並列して形成される。筒状の空間15は、以下に述べる把手20が挿入可能なものである。   In addition to the joining by the joining line 14, the left and right side portions of the handle mounting sheets 13a and 13b are also joined. That is, in the handle mounting sheets 13a and 13b, their widthwise center portions are joined linearly along the longitudinal direction, and their left and right side portions are joined linearly along the longitudinal direction. . As a result, a cylindrical space 15 extending in the longitudinal direction of the cleaning article 10 is formed in parallel by the two grip mounting sheets 13a and 13b. The cylindrical space 15 can be inserted with a handle 20 described below.

把手20は把持部21と把持部の先端から二股に分岐した挿入部22,22とを備えている。把持部21と挿入部22とは所定の角度をなしている。挿入部22は細長い扁平な板状の形状をしている。挿入部22がこのような形状となっていることで、挿入部22に可撓性が付与される。このことは、曲面や凹凸を有する清掃対象面を清掃した場合に、清掃用物品10が清掃対象面に追従し易くなり、埃の除去効率が高まる観点から有利である。各挿入部22は、2枚の把手装着用シート13a,13bによって形成される空間15内にそれぞれ挿入される。挿入部22,22間には、挿入部22よりも短い長さを有するフック部23が設けられている。フック部23はその先端が所定の角度をなして上方を向いている。フック部23は、挿入部22が空間15内に挿入された状態で清掃用物品10と係合することで、挿入部22が清掃用物品10から抜けにくくする働きを有している。   The handle 20 includes a gripping portion 21 and insertion portions 22 and 22 that are bifurcated from the tip of the gripping portion. The grip portion 21 and the insertion portion 22 form a predetermined angle. The insertion portion 22 has an elongated flat plate shape. Since the insertion portion 22 has such a shape, flexibility is imparted to the insertion portion 22. This is advantageous from the viewpoint of increasing the dust removal efficiency because the cleaning article 10 can easily follow the surface to be cleaned when the surface to be cleaned having a curved surface or unevenness is cleaned. Each insertion portion 22 is inserted into a space 15 formed by two grip mounting sheets 13a and 13b. A hook portion 23 having a shorter length than the insertion portion 22 is provided between the insertion portions 22 and 22. The hook portion 23 has its tip turned upward at a predetermined angle. The hook portion 23 has a function of preventing the insertion portion 22 from coming out of the cleaning article 10 by engaging with the cleaning article 10 in a state where the insertion portion 22 is inserted into the space 15.

本実施形態の清掃用物品10においては、掻き出し用シート12a,12bとして、バルクソフトネスの最大荷重値が0.2〜4.0N/mm、好ましくは0.3〜3.0N/mmのものを使用することを特徴としている。バルクソフトネスの最大荷重値は、掻き出し用シート12a,12bの剛性の高さの尺度となるものである。バルクソフトネスの最大荷重値が大きいほど、掻き出し用シート12a,12bはその剛性が高いことを意味する。本実施形態の清掃用物品10においては、掻き出し用シート12a,12bのバルクソフトネスの最大荷重値を0.2N/mm以上とすることで、掻き出し用シート12a,12bに十分な剛性が付与され、隅部に溜まった埃を容易に掻き出すことができ、また清掃対象面にこびりついたゴミを容易に掻き取ることができる。一方、バルクソフトネスの最大荷重値を4.0N/mm以下とすることで、清掃対象面に引っ掻き傷などの損傷が発生することが効果的に防止される。   In the cleaning article 10 of the present embodiment, the maximum load value of bulk softness is 0.2 to 4.0 N / mm, preferably 0.3 to 3.0 N / mm, as the scraping sheets 12a and 12b. It is characterized by using. The maximum load value of the bulk softness is a measure of the rigidity of the scraping sheets 12a and 12b. It means that the larger the maximum load value of the bulk softness, the higher the rigidity of the scraping sheets 12a and 12b. In the cleaning article 10 of the present embodiment, sufficient rigidity is imparted to the scraping sheets 12a and 12b by setting the maximum load value of the bulk softness of the scraping sheets 12a and 12b to 0.2 N / mm or more. The dust accumulated in the corners can be easily scraped off, and the dust stuck on the surface to be cleaned can be easily scraped off. On the other hand, by setting the maximum load value of the bulk softness to 4.0 N / mm or less, the occurrence of damage such as scratches on the surface to be cleaned is effectively prevented.

バルクソフトネスの最大荷重値は次の方法で測定される。掻き出し用シート12a,12bをその長手方向に150mm、幅方向に30mmの寸法で矩形に切り出す。切り出されたシートを、その長辺が周方向となるように丸めて、高さ30mm、円周140mmの円筒を形成する。その際、ステープラーを用いて円筒形状を保持する。テンシロン引張試験器に円筒を設置し、10mm/minの圧縮モードで円筒を圧縮する。圧縮の荷重を測定し、その最大値をもってバルクソフトネスの最大荷重値とする。試験は4個の試料について行い、測定結果の平均値を算出する。   The maximum load value of bulk softness is measured by the following method. The scraping sheets 12a and 12b are cut into rectangles with dimensions of 150 mm in the longitudinal direction and 30 mm in the width direction. The cut sheet is rounded so that the long side thereof is in the circumferential direction to form a cylinder having a height of 30 mm and a circumference of 140 mm. At that time, a cylindrical shape is held using a stapler. A cylinder is installed in a Tensilon tensile tester, and the cylinder is compressed in a compression mode of 10 mm / min. Measure the compression load and use the maximum value as the maximum load value for bulk softness. The test is performed on four samples, and the average value of the measurement results is calculated.

本実施形態の清掃用物品10における埃やゴミの掻き出し・保持機構は次の通りである。図1に示すように、清掃作業前の状態の清掃用物品10においては、繊維層11a〜11dを構成する繊維はその先端部が、掻き出し用シート12a,12bにおける左右の側縁部を越えて存在している。従って、掻き出し用シート12a,12bにおける左右の側縁部は、外部に露出していない。つまり、この状態では、清掃用物品10は、繊維層11a〜11dを構成する繊維のみが外部に露出している。このような状態は、テーブルの上やテレビの画面、タンス、冷蔵庫といった比較的広い面積の部分に存する埃を、繊維間に絡めて除去するのに好適な状態である。また、掻き出し用シート12a,12bにおける左右の側縁部は、外部に露出していないので、清掃対象面に傷がつくおそれもない。   The dust / dust scraping / holding mechanism in the cleaning article 10 of the present embodiment is as follows. As shown in FIG. 1, in the cleaning article 10 in a state before the cleaning operation, the fibers constituting the fiber layers 11a to 11d have their leading ends exceeding the left and right side edges of the scraping sheets 12a and 12b. Existing. Accordingly, the left and right side edges of the scraping sheets 12a and 12b are not exposed to the outside. That is, in this state, in the cleaning article 10, only the fibers constituting the fiber layers 11a to 11d are exposed to the outside. Such a state is suitable for removing dust existing on a relatively large area such as a table, a television screen, a chiffon, and a refrigerator by entanglement between fibers. Further, since the left and right side edges of the scraping sheets 12a and 12b are not exposed to the outside, there is no possibility that the surface to be cleaned is damaged.

一方、隅部や壁と家具の間の隙間などを清掃する場合には、清掃用物品10を押し付ける動作を伴うので、清掃用物品10に或る程度の力が加わる。繊維層11a〜11dを構成する繊維は一般にコシが弱いので、加えられた力によって屈曲しやすい。これに対して、掻き出し用シート12a,12bは前述したバルクソフトネス値を有しているので、加えられた力によっても屈曲しづらい。その結果、加えられた力によって繊維層11a〜11dを構成する繊維が相対的に後退して、掻き出し用シート12a,12bにおける左右の側縁部が清掃用物品10の外部に露出する。露出した側縁部はそのバルクソフトネス値が高いので、隅部や隙間に存する埃を容易に掻き出す。掻き出された埃は繊維によって絡め取られて除去される。清掃対象面にこびりついたゴミの掻き取り、除去も同様の機構によって行われる。   On the other hand, when cleaning a corner or a gap between the wall and the furniture, etc., an operation of pressing the cleaning article 10 is involved, so that a certain amount of force is applied to the cleaning article 10. Since the fibers constituting the fiber layers 11a to 11d are generally weak, they are easily bent by the applied force. On the other hand, the scraping sheets 12a and 12b have the above-described bulk softness value, and thus are difficult to bend even by an applied force. As a result, the fibers constituting the fiber layers 11 a to 11 d are relatively retracted by the applied force, and the left and right side edges of the scraping sheets 12 a and 12 b are exposed to the outside of the cleaning article 10. Since the exposed side edge portion has a high bulk softness value, it easily scrapes off dust present in corners and gaps. The scraped dust is entangled by the fibers and removed. The same mechanism is used to scrape and remove dust stuck to the surface to be cleaned.

以上の説明から明らかなように、隅部に溜まった埃の掻き出しや、清掃対象面にこびりついたゴミの掻き取りに大きく寄与するのは、掻き出し用シート12a,12bにおける左右の側縁部の部位である。従って、側縁部の部位の剛性を、掻き出し用シート12a,12bにおける他の部位よりも高めることが一層効果的である。例えば、(イ)側縁部を折り返して二重構造にするか、(ロ)側縁部に、掻き出し用シート12a,12bの構成材料と同種又は異種の材料を貼り合わせて、側縁部の部位の剛性を高めることができる。これらの場合には、先に述べたバルクソフトネスの最大荷重値は、側縁部の剛性を高めた部位を対象として測定される。   As is apparent from the above description, the left and right side edge portions of the scraping sheets 12a and 12b greatly contribute to scraping off dust accumulated in the corners and scraping of dust stuck to the surface to be cleaned. It is. Accordingly, it is more effective to increase the rigidity of the side edge portion than the other portions of the scraping sheets 12a and 12b. For example, (a) the side edge portion is folded to form a double structure, or (b) the same or different material as the constituent material of the scraping sheets 12a, 12b is bonded to the side edge portion. The rigidity of the part can be increased. In these cases, the maximum load value of the bulk softness described above is measured for a portion where the rigidity of the side edge portion is increased.

隅部に溜まった埃の掻き出しや、清掃対象面にこびりついたゴミの掻き取り効果を一層高める観点から、掻き出し用シート12a,12bは、1枚のシート形状を保っていることが好ましい。逆に、掻き出し用シート12a,12bに、先に述べた特許文献2に記載の短冊片が形成されていることは、埃の掻き出しや、ゴミの掻き取り効果の点からはマイナスに作用する。換言すれば、掻き出し用シート12a,12bには、その幅方向に延びる短冊片が形成されるような深い切り込みが設けられていないことが好ましい。   From the viewpoint of further enhancing the effect of scraping off dust accumulated in the corners and scraping off the dust stuck to the surface to be cleaned, it is preferable that the scraping sheets 12a and 12b maintain a single sheet shape. On the contrary, the fact that the strips described in Patent Document 2 described above are formed on the scraping sheets 12a and 12b acts negatively in terms of dust scraping and dust scraping effects. In other words, it is preferable that the scraping sheets 12a and 12b are not provided with a deep notch that forms strips extending in the width direction.

隅部に溜まった埃の掻き出しや、清掃対象面にこびりついたゴミの掻き取り効果を更に一層高める観点から、図2に示すように、掻き出し用シート12a,12bにおける左右の側縁部は波形になっていることが好ましい。図2には波形の一例として、側縁部が鋸歯状になっている状態が示されている。しかし、波形の形状はこれに限られず、他の形状、例えば正弦派の形状、台形の繰り返しの形状、或いは種々の形状を組み合わせた形状であってもよい。   As shown in FIG. 2, the left and right side edges of the scraping sheets 12a and 12b are corrugated from the viewpoint of further enhancing the effect of scraping dust accumulated in the corners and scraping off dust stuck to the surface to be cleaned. It is preferable that FIG. 2 shows a state in which the side edge portion has a sawtooth shape as an example of the waveform. However, the shape of the waveform is not limited to this, and other shapes such as a sinusoidal shape, a trapezoidal repeated shape, or a combination of various shapes may be used.

前述の通り、掻き出し用シート12a,12bは、或る程度の剛性を有するものである。従って、その左右両側部だけでなく、図1及び図2に示すように、その全体が清掃用物品10の表面に露出しないことが好ましい。即ち、掻き出し用シートは隣り合う繊維層間に配置されており、清掃用物品10の表面に位置していないことが好ましい。   As described above, the scraping sheets 12a and 12b have a certain degree of rigidity. Therefore, it is preferable that not only the left and right side portions but also the entirety thereof is not exposed on the surface of the cleaning article 10 as shown in FIGS. 1 and 2. That is, it is preferable that the scraping sheet is disposed between adjacent fiber layers and is not located on the surface of the cleaning article 10.

本実施形態の清掃用物品10を構成する各部材の詳細について説明すると、各繊維層11a〜11dを構成する繊維としては、繊維長が30〜150mm、特に50〜120mmのものを用いることが、埃の絡み取り性の点から好ましい。本実施形態においては、このような繊維長を有する繊維を繊維束(トウ)の状態で用いる。その際には公知の開繊装置を用いて繊維を十分に開繊しておくことが好ましい。   The details of each member constituting the cleaning article 10 of the present embodiment will be described. As the fibers constituting the fiber layers 11a to 11d, fibers having a fiber length of 30 to 150 mm, particularly 50 to 120 mm are used. This is preferable from the viewpoint of dust entanglement. In the present embodiment, fibers having such a fiber length are used in a fiber bundle (tow) state. In that case, it is preferable to sufficiently open the fibers using a known opening device.

繊維として特に捲縮繊維を用いると、埃の絡み取り性が一層向上するので好ましい。繊維の捲縮数は1cm当たり1〜10個、特に3〜8個であることが好ましい。   It is preferable to use crimped fibers as the fibers because dust entanglement is further improved. The number of crimps of the fiber is preferably 1 to 10, particularly 3 to 8 per 1 cm.

繊維の太さは本発明において特に臨界的ではないが、埃の絡み取り性や、清掃対象面への傷付き防止性の観点から、1〜30dtex、特に2〜10dtexであることが好ましい。   The thickness of the fiber is not particularly critical in the present invention, but is preferably 1 to 30 dtex, particularly 2 to 10 dtex, from the viewpoints of dust entanglement and prevention of scratches on the surface to be cleaned.

繊維の構成材料も本発明においては特に臨界的ではない。例えば、通常用いられている熱可塑性樹脂を原料とする繊維を用いることができる。各繊維層11a〜11dを、掻き出し用シート12a,12b及び把手装着用シート13a,13bと熱融着によって接合する場合には、繊維は、芯鞘構造を有する熱融着性複合繊維であることが好ましい。   The constituent material of the fiber is not particularly critical in the present invention. For example, it is possible to use fibers that are made from a thermoplastic resin that is usually used. When each of the fiber layers 11a to 11d is bonded to the scraping sheets 12a and 12b and the handle mounting sheets 13a and 13b by heat fusion, the fibers are heat-fusible conjugate fibers having a core-sheath structure. Is preferred.

各繊維層11a〜11dの坪量はそれぞれ50〜400g/m2、特に100〜300g/m2であることが好ましい。この場合、各繊維層11a〜11dの坪量は同じでもよく、或いは異なっていてもよい。 The basis weight of each of the fiber layers 11a to 11d is preferably 50 to 400 g / m 2 , particularly preferably 100 to 300 g / m 2 . In this case, the basis weights of the fiber layers 11a to 11d may be the same or different.

実施例及び比較例で得られた清掃用物品10に、図1及び図2に示す把手20を取り付けて清掃操作を行い、清掃性を評価した。清掃性は、埃の掻き出し性及び操作性の観点からの評価とした。
[Evaluation]
A cleaning operation was performed by attaching the handle 20 shown in FIGS. 1 and 2 to the cleaning article 10 obtained in the examples and comparative examples, and the cleaning performance was evaluated. The cleanability was evaluated from the viewpoint of dust scraping and operability.

〔埃の掻き出し性〕
キーボード(HITACHI PC-KB5310)の上にコットンリンタ0.1gを均一に撒き、キーボードの溝に掻き出しシートを合わせ、長手方向に10回往復清掃をする。溝に追従してコットンリンタ(ほこり)が掻きだせたかを確認するとともに、キーボードに残ったコットンリンタの重量を測定した。残った量が、0.07g以上0.1g以下の場合は埃を掻き出せないと判定し、×とした。残った量が、0.03g以上0.07g未満の場合は埃がやや残ると判定し、△とした。残った量が、0.0g以上0.03g未満の場合は埃がきれいに掻き出せる判定し、○とした。
[Dust scavenging]
Spread 0.1g of cotton linter uniformly on the keyboard (HITACHI PC-KB5310), align the scraped sheet with the keyboard groove, and clean it 10 times in the longitudinal direction. Following the groove, it was confirmed whether the cotton linter (dust) was scraped off, and the weight of the cotton linter remaining on the keyboard was measured. When the remaining amount was not less than 0.07 g and not more than 0.1 g, it was determined that dust could not be scraped out, and x was determined. When the remaining amount was 0.03 g or more and less than 0.07 g, it was determined that a little dust remained, and was set as Δ. When the remaining amount was 0.0 g or more and less than 0.03 g, it was determined that dust could be scraped cleanly.

〔操作性〕
キーボード(HITACHI PC-KB5310)の溝に掻きだしシートが入れ易いかを確認するとともに、長手方向に10回往復させ、シートが溝から外れないか確認した。10往復させても溝からシートが外れない場合は操作しやすいと判定し、○とした。10往復を終了する前に、溝からシートが外れた場合はやや操作しやすいと判定し、△とした。溝にシートを入れるのに、手を添える必要があった場合には操作しにくいと判定し、×とした。
[Operability]
The keyboard (HITACHI PC-KB5310) was checked to see if it was easy to put the scraped sheet into the groove, and it was reciprocated 10 times in the longitudinal direction to confirm that the sheet did not come off the groove. If the sheet did not come off the groove even after 10 reciprocations, it was determined that it was easy to operate, and it was marked as ◯. When the sheet was removed from the groove before 10 round trips were completed, it was determined that the operation was somewhat easy, and the result was set as Δ. When it was necessary to put a hand to put a sheet into the groove, it was determined that the operation was difficult, and x was assigned.
