Description

本発明は、粘着性と剥離性を有する粘着剤層を備えた支持体を、装着した携帯用消しゴムであり、ノートや手帳の任意の紙面に、本携帯用消しゴムを貼り付けるという保持形態を、提案することを、目的とする。 The present invention aims to propose a portable eraser equipped with a support provided with an adhesive layer that has adhesive properties and releasability, and a holding form in which the portable eraser can be attached to any page of a notebook or planner.

消しゴムを携帯し、字消しを行う方法として、特開２０１１－３１４２４号公報のように、クリップ付きの消しゴム付筆記具を利用する方法や、特開２０１７－１５９５２５号公報のように、クリップ付きの消しゴムホルダーを利用する方法があり、これらの方法は、消しゴムを携帯し、字消しを行うのには十分であった。 Methods for carrying an eraser and erasing include using a writing implement with an eraser attached to a clip, as in JP 2011-31424 A, and using an eraser holder with a clip, as in JP 2017-159525 A. These methods are sufficient for carrying an eraser and erasing.

しかし、これらの方法に代表される従来の消しゴムの携帯方法は、消しゴムを、保持する特定の保管場所の提案を行うものではなく、字消し作業開始において、消しゴムを探す手間が、発生し、時間がかかる場合があるという、問題があった。 However, these and other conventional methods of carrying an eraser do not suggest a specific storage location for the eraser, which can result in the time-consuming and time-consuming effort of searching for the eraser when starting to erase.

特開２０１７－１５９５２５号公報Japanese Patent Application Laid-Open No. 2017-159525

消しゴムの携帯において、その保管場所を探す手間を省き、字消し作業の利便性を、向上させることが、第一の課題である。 When carrying an eraser, the first challenge is to eliminate the hassle of searching for a place to store it and improve the convenience of erasing.

この、第一の課題の、解決手段に用いる、粘着性と剥離性を有する粘着剤層を備えた携帯用消しゴムが、携帯時に、その重量により、被着面から、脱落することを、防止することが、第二の課題である。 The second challenge is to prevent a portable eraser, which is used as a solution to the first challenge and has an adhesive layer with adhesive and releasability, from falling off from the surface to which it is attached due to its weight when carried.

第二の課題において、消しゴムの軽量化は、字消しを行う消しゴム部分を、少なくするため、字消し機能に不利に働き、また、消しゴムの重量に対する支持体（ＳＰ）の粘着力の強化は、剥離性機能に不利に働く。 In the second issue, reducing the weight of the eraser reduces the part of the eraser that erases, which is detrimental to the erasing function, and strengthening the adhesive strength of the support (SP) relative to the weight of the eraser is detrimental to the releasability function.

これらの、構成部分毎の対応策は、互いの機能に不利に働き、相反するため、構成部分相互の機能の、最適な形態を、見出すことが、必要であった。 These countermeasures for each component part were detrimental to each other's functions and contradicted each other, so it was necessary to find the optimal form for the mutual functioning of the components.

粘着性と剥離性を、備えた粘着剤層を有する粘着面（ＡＳ）を消しゴムに装着した、携帯用消しゴムの、形態を利用して、ノートや手帳の、任意の紙面（ＴＰ）との間においての、携帯用消しゴムの保持形態（ＨＳ）を、構成する。ノートや手帳に、限らず、複数の紙面が綴られたものにおける、任意の紙面（ＴＰ）との間においても、携帯用消しゴムの保持形態（ＨＳ）を、構成できる。 The portable eraser has an adhesive surface (AS) with an adhesive layer that has both adhesiveness and releasability attached to it, and by utilizing this, the portable eraser's holding form (HS) can be configured between any page (TP) of a notebook or planner. The portable eraser's holding form (HS) can also be configured between any page (TP) of a notebook or planner, not just a notebook or planner, but also a book with multiple pages bound together.

この、携帯用消しゴムの保持形態（ＨＳ）は、ノートや手帳を、開いた時の、保持形態（ＨＳ１）と、ノートや手帳を、閉じた時の、保持形態（ＨＳ２）の、二つの形態を有するものとする。 This portable eraser has two holding forms (HS): a holding form (HS1) when the notebook or planner is open, and a holding form (HS2) when the notebook or planner is closed.

保持形態（ＨＳ１）は、前述の任意の紙面（ＴＰ）の側面（ＮＷ）の外側に、消しゴムを、配置するように、支持シート部分（ＳＳ）の、粘着面（ＡＳ）を、任意の紙面（ＴＰ）に、貼り付ける形態とする。 The holding form (HS1) is a form in which the adhesive surface (AS) of the support sheet portion (SS) is attached to any paper surface (TP) so that the eraser is positioned on the outside of the side (NW) of the aforementioned any paper surface (TP).

保持形態（ＨＳ１）により、ノートや手帳の、任意の紙面（ＴＰ）を、携帯用消しゴムの、使用場所で、かつ保管場所とすることにより、消しゴムを探す手間を省くことが、できる。この、保持形態（ＨＳ１）が、第一の課題の解決手段である。 The storage form (HS1) allows any page (TP) in a notebook or planner to be used and stored as the place to use the portable eraser, eliminating the need to search for the eraser. This storage form (HS1) is a solution to the first problem.

消しゴムを、任意の紙面（ＴＰ）の、外側に配置する，保持形態（ＨＳ１）において、ノートや手帳を閉じて、携帯用消しゴムを紙面と紙面の間に挟み、粘着面（ＡＳ）を密着させて、保持形態（ＨＳ２）を、構成することにより、携帯用消しゴムを携帯できる。 In the holding form (HS1) where the eraser is placed on the outside of any paper surface (TP), the notebook or planner can be closed and the portable eraser sandwiched between the pages, with the adhesive surface (AS) pressed against the paper, forming the holding form (HS2), allowing the portable eraser to be carried around.

この、保持形態（ＨＳ２）により、消しゴムの重量による、支持シート部分（ＳＳ）を、紙面から剥す力よりも、粘着面（ＡＳ）の、粘着力を、強くして、携帯用消しゴムの、脱落防止ができる。この保持形態（ＨＳ２）が、第二の課題の解決手段である。 This holding configuration (HS2) makes the adhesive strength of the adhesive surface (AS) stronger than the force that peels the support sheet portion (SS) from the paper due to the weight of the eraser, preventing the portable eraser from falling off. This holding configuration (HS2) is a means of solving the second problem.

保持形態（ＨＳ２）により、脱落防止をして、携帯用消しゴムを携帯できる。 The holding configuration (HS2) prevents the eraser from falling out, allowing you to carry it with you.

ノートや手帳の、任意の紙面を、携帯用消しゴムの使用場所で、かつ、保管場所とすることにより、消しゴムを探す手間を省き、字消し作業が、すぐにできる。 By using and storing your portable eraser on any page in your notebook or planner, you can eliminate the hassle of searching for the eraser and start erasing immediately.

保持形態（ＨＳ１）や保持形態（ＨＳ２）において、ノートや手帳の側面で、消しゴムの、重量を支え、携帯用消しゴムの、脱落防止ができる。 In the holding form (HS1) and holding form (HS2), the side of the notebook or planner supports the weight of the eraser, preventing the portable eraser from falling off.

保持形態（ＨＳ２）により、粘着面（ＡＳ）を、紙面と紙面の間に挟み、密着させて、携帯用消しゴムを携帯できる。 The holding configuration (HS2) allows the adhesive surface (AS) to be sandwiched between two pieces of paper, allowing the portable eraser to be carried around.

本携帯用消しゴムが、 ノートや手帳の、使用場所の目印となり、複数の、携帯用消しゴムを、ノートや手帳の、任意の紙面に、貼り付けることができる。 This portable eraser can be used as a marker to mark the location of a notebook or planner, and multiple portable erasers can be attached to any page in a notebook or planner.

Ｚ方向で、上から順に、支持版（ＳＵ）部分の上面と、重なり部分（ＬＶ１）と、消しゴムと、底板（ＳＢ）を、Ｚ方向で上下に、指で挟んで字消しを行うときや、携帯用消しゴムを、任意の紙面から剥がす時の、消しゴムの湾曲を、本携帯用消しゴムの支持版部分で支える形態により、消しゴムの割れを防ぐことができる。 When erasing by pinching the top surface of the support plate (SU), overlapping portion (LV1), eraser, and bottom plate (SB) with your fingers from top to bottom in the Z direction, or when peeling the portable eraser off any paper, the support plate of this portable eraser supports the eraser's curve, preventing the eraser from cracking.

前述の、Ｚ方向で、上から順に、支持版（ＳＵ）部分の上面と、重なり部分（ＬＶ１）と、消しゴムと、底板（ＳＢ）を、Ｚ方向で上下に、指で挟むことにより、携帯用消しゴムを、保管場所から、取り出して、字消しを行い、その後、携帯用消しゴムを、保管場所に保管するという、一連の作業が、円滑にできる。 By pinching the top surface of the support plate (SU), the overlapping portion (LV1), the eraser, and the bottom plate (SB) with your fingers from top to bottom in the Z direction, as mentioned above, you can smoothly perform the series of steps of taking the portable eraser out of its storage location, erasing, and then storing it back in its storage location.

図１に、ノートや手帳が開いているときの、請求項１に記述の、保持形態（ＨＳ１）を示す。片面に粘着面を有する支持シート部分（ＳＳ）と支持版部分（ＳＵ）を、装着した携帯用消しゴムの、消しゴム（ＥＲ）が、ノートや手帳の、側面（ＮＷ）の外側になるように、任意の紙面（ＴＰ）に、支持シート部分（ＳＳ）を貼り付けた形態である。この形態は、消しゴム（ＥＲ）の重量により、支持版（ＳＵ）が湾曲して、消しゴム（ＥＲ）を、ノートや手帳の、側面（ＮＷ）で、支えるという特徴を有する。また、この携帯用消しゴムを貼り付けた、任意の紙面（ＴＰ）が、本携帯用消しゴムの保管場所（ＨＰ）であり、使用場所（ＵＰ）となる。図２に、ノートや手帳を閉じているときの、請求項１に記述の、保持形態（ＨＳ２）を示す。ノートや手帳を閉じる時には、支持シート部分（ＳＳ）の、粘着面（ＡＳ）を任意の紙面（ＴＰ）に密着させて、ノートの端の外側に消しゴム部分を配置して、携帯できる。 Figure 1 shows the holding form (HS1) described in claim 1 when the notebook or planner is open. This form is a portable eraser equipped with a support sheet portion (SS) and a support plate portion (SU) with an adhesive surface on one side, with the support sheet portion (SS) attached to any paper surface (TP) so that the eraser (ER) is on the outside of the side (NW) of the notebook or planner. This form has the characteristic that the support plate (SU) curves due to the weight of the eraser (ER), supporting the eraser (ER) on the side (NW) of the notebook or planner. Furthermore, the any paper surface (TP) to which this portable eraser is attached is the storage location (HP) and use location (UP) of this portable eraser. Figure 2 shows the holding form (HS2) described in claim 1 when the notebook or planner is closed. When closing the notebook or planner, simply press the adhesive surface (AS) of the support sheet (SS) against any paper surface (TP) and place the eraser part on the outside edge of the notebook for easy portability.

図３と図４と図５と図６に、請求項１に示す、携帯用消しゴムの実施例１を示す。図３では、支持体（ＳＰ）の構成部分である支持シート部分（ＳＳ）と、支持版部分（ＳＵ）の部分を、説明のため、区分して表示している。 Figures 3, 4, 5, and 6 show Example 1 of the portable eraser set forth in claim 1. In Figure 3, the support sheet portion (SS) and support plate portion (SU), which are components of the support body (SP), are shown separately for ease of explanation.

図４において、支持シート部分（ＳＳ）と、支持版部分（ＳＵ）を区分して表示しない、一体化された支持体（ＳＰ）を表示している。 In Figure 4, the support sheet portion (SS) and the support plate portion (SU) are not shown separately, but rather as an integrated support body (SP).

図３に示す、支持版部分（ＳＵ）は、消しゴム（ＥＲ）の一部分を覆う形態を有する。また、図３と図６に示すように、ＸＹＺ座標のＺ方向において、支持版部分（ＳＵ）は、消しゴム（ＥＲ）の、上面の一部分との間に、灰色の部分で示す、重なり部分（ＬＶ１）を有する。これにより、消しゴム（ＥＲ）を、支える形態である。 The support plate portion (SU) shown in Figure 3 has a configuration that covers part of the eraser (ER). Also, as shown in Figures 3 and 6, in the Z direction of the XYZ coordinate system, the support plate portion (SU) has an overlapping portion (LV1), shown as a gray area, between it and part of the top surface of the eraser (ER). This allows it to support the eraser (ER).

図５に示す、支持シート部分（ＳＳ）の片面にある粘着層（ＡＳ）が、前述の図１のように、ノートや手帳の、任意の紙面（ＴＰ）に、貼り付けられる。 The adhesive layer (AS) on one side of the support sheet portion (SS) shown in Figure 5 is attached to any paper surface (TP) of a notebook or planner, as shown in Figure 1 above.

図６は、Ｚ方向の下方向から見た図であり、消しゴム（ＥＲ）を除いて表示し、かつ、支持版部分（ＳＵ）の側面（ＳＷ１）と側面（ＳＷ２）と底板（ＳＢ）の部分を透明にして、重なり部分（ＬＶ１）を灰色で示している。この灰色部分が、支持版部分（ＳＵ）と消しゴム（ＥＲ）の重なり部分（ＬＶ１）である。 Figure 6 is a view from below in the Z direction, with the eraser (ER) removed, and the sides (SW1), (SW2) and bottom plate (SB) of the support plate portion (SU) being transparent, with the overlapping portion (LV1) shown in gray. This gray portion is the overlapping portion (LV1) of the support plate portion (SU) and the eraser (ER).

図７に、請求項２に記述の、支持シート部分（ＳＳ）の、短手方向（ＤＳ）と、長手方向（ＤＬ）の形態を示す。支持シート部分（ＳＳ）の、短手方向（ＤＳ）に、支持版（ＳＵ）に支えられる、消しゴム（ＥＲ）が位置する形態である。 Figure 7 shows the configuration of the support sheet portion (SS) in the short-side direction (DS) and long-side direction (DL) as described in claim 2. In this configuration, the eraser (ER) supported by the support plate (SU) is located in the short-side direction (DS) of the support sheet portion (SS).

図７と図８に、請求項４に記述の、重なり部分（ＬＶ２）の形態を示す。支持シート部分（ＳＳ）の、長手方向（ＤＬ）の一端と、支持版部分（ＳＵ）とが、Ｚ方向に対して、重なる部分が、重なり部分（ＬＶ２）である。 7 and 8 show the configuration of the overlapping portion (LV2) described in claim 4. The overlapping portion (LV2) is the portion where one end of the support sheet portion (SS) in the longitudinal direction (DL) and the support plate portion (SU) overlap in the Z direction.

図８に、請求項３に記述の、支持シート部分（ＳＳ）の粘着面（ＡＳ）の粘着剤層が、ＸＹ平面上に、間欠的に複数個形成される形態を示す。短手方向（ＤＳ）の個々の、粘着剤層の間隔が、長手方向（ＤＬ）の個々の、粘着剤層の間隔よりも広いという形態である。 8 shows a configuration in which a plurality of adhesive layers are formed intermittently on the XY plane on the adhesive surface (AS) of the support sheet portion (SS) as described in claim 3. In this configuration, the spacing between the individual adhesive layers in the short direction (DS) is wider than the spacing between the individual adhesive layers in the long direction (DL).

図９に、請求項３と請求項４に記述の、形態を示す。支持シート部分（ＳＳ）を透明にして、粘着面（ＡＳ）を灰色で示している。また、支持シート部分（ＳＳ）の粘着面（ＡＳ）を、意図的に剥す方向（ＤＲ）が、長手方向（ＤＬ）に対して、斜めである様子を示す。また、剥す部分の粘着面（ＡＳ）と任意の紙面（ＴＰ）との間の接触部分（ＬＣ）は、支持シート部分（ＳＳ）を剥した部分と、剥していない部分との境界上にある部分を示すものとする。接触部分（ＬＣ）の方向は、短手方向（ＤＳ）と長手方向（ＤＬ）に対して、斜めであるため、短手方向（ＤＳ）の個々の粘着剤層の間隔が広い分、この接触部分（ＬＣ）が、少なくなる。その分、任意の紙面（ＴＰ）から、支持シート部分（ＳＳ）を、剥がす力が、弱くなり、意図的に支持シート部分（ＳＳ）を剥す場合は、支持シート部分（ＳＳ）を、任意の紙面（ＴＰ）から剥しやすくなる。一方、この形態における、消しゴム（ＥＲ）の重量による、支持シート部分（ＳＳ）を、紙面から剥す力に対しての、粘着面（ＡＳ）の粘着力への影響は、短手方向（ＤＳ）が、任意の紙面（ＴＰ）の側面（ＮＷ）の方向にあり、この（ＮＷ）方向への、粘着面（ＡＳ）の面積は広くとれるため、少なくできる。 Figure 9 shows the configurations described in claims 3 and 4. The support sheet portion (SS) is shown transparent, and the adhesive surface (AS) is shown in gray. It also shows how the intentional peeling direction (DR) of the adhesive surface (AS) of the support sheet portion (SS) is oblique to the longitudinal direction (DL). The contact portion (LC) between the adhesive surface (AS) of the peeling portion and an arbitrary paper surface (TP) indicates the portion on the boundary between the peeled and unpeeled portions of the support sheet portion (SS). Because the direction of the contact portion (LC) is oblique to the transverse direction (DS) and the longitudinal direction (DL), the wider the spacing between the individual adhesive layers in the transverse direction (DS), the smaller the contact portion (LC). Therefore, the force required to peel the support sheet portion (SS) from any paper surface (TP) is weakened, and when intentionally peeling the support sheet portion (SS), it becomes easier to peel the support sheet portion (SS) from any paper surface (TP). On the other hand, in this form, the influence of the weight of the eraser (ER) on the adhesive strength of the adhesive surface (AS) against the force required to peel the support sheet portion (SS) from the paper surface is reduced because the short side direction (DS) is in the direction of the side (NW) of the any paper surface (TP), and the area of the adhesive surface (AS) in this (NW) direction can be made wider.

図１０に、請求項５に記述の、形態を示す。請求項１と、請求項２に記述の、支持版部分（ＳＵ）の、側面（ＳＷ１）と、側面（ＳＷ２）と、底板（ＳＢ）が、削除される形態を有し、支持版部分（ＳＵ）と消しゴム（ＥＲ）の上面との間の重なり部分（ＬＶ１）を灰色で示しており、この部分に、接着層（ＡＳ２）を有し、この部分で、支持版部分（ＳＵ）と消しゴム（ＥＲ）とが、接合される形態である。 Figure 10 shows the configuration described in claim 5. This configuration has the same configuration as claims 1 and 2, in which the side surfaces (SW1), (SW2), and bottom plate (SB) of the support plate portion (SU) are removed. The overlapping portion (LV1) between the support plate portion (SU) and the top surface of the eraser (ER) is shown in gray. This portion has an adhesive layer (AS2), and this portion is where the support plate portion (SU) and the eraser (ER) are joined.

The adhesive surface (AS) of the support sheet portion (SS) is tightly attached between the overlapping and closed paper surfaces to form the eraser (ER). ) the adhesive strength of the adhesive surface (AS) is stronger than the force required to peel the support sheet part (SS) from the paper due to the weight of the paper, preventing the portable eraser from falling off and allowing the portable eraser to be carried around; in this holding form (HS1) and holding form (HS2), any paper surface (TP) to which the portable eraser is attached becomes the place of use (UP) and storage place (HP) for the portable eraser, eliminating the need to search for the eraser when starting to erase. 請求項１において、支持シート部分（ＳＳ）が、短手方向（ＤＳ）と、長手方向（ＤＬ）を有する形態を有し、また、 請求項１に、記載の支持版部分（ＳＵ）で支えられている、消しゴム（ＥＲ）が、支持シート部分（ＳＳ）の、短手方向（ＤＳ）に、位置するという、形態を有し、この、形態により、請求項１の、保持形態（ＨＳ１）において、支持シート部分（ＳＳ）の、粘着面（ＡＳ）の短手方向（ＤＳ）に、任意の紙面（ＴＰ）の側面（ＮＷ）が、位置するため、この、側面（ＮＷ）方向への、粘着面（ＡＳ）の面積が増えるという、特徴を有し、このため、消しゴム（ＥＲ）の重量による、支持シート部分（ＳＳ）を、紙面から剥す力に対しての、粘着面（ＡＳ）の粘着力が、より強くなり、消しゴムの脱落を防ぐという特徴を有する携帯用消しゴム。 A portable eraser as claimed in claim 1, characterized in that the support sheet portion (SS) has a configuration with a short side direction (DS) and a long side direction (DL), and the eraser (ER) supported by the support plate portion (SU) as claimed in claim 1 is positioned in the short side direction (DS) of the support sheet portion (SS). Due to this configuration, in the holding configuration (HS1) of claim 1, the side surface (NW) of any paper surface (TP) is positioned in the short side direction (DS) of the adhesive surface (AS) of the support sheet portion (SS), thereby increasing the area of the adhesive surface (AS) in this side (NW) direction. Therefore, the adhesive strength of the adhesive surface (AS) is stronger against the force exerted by the weight of the eraser (ER) to peel the support sheet portion (SS) from the paper surface, preventing the eraser from falling off. 請求項２において、支持シート部分（ＳＳ）の粘着面（ＡＳ）の粘着剤層が、 ＸＹ平面上に、間欠的に複数個形成される形態を有し、短手方向（ＤＳ）と長手方向（Ｄ Ｌ）の個々の粘着剤層の間隔が、等しい形態（ＥＳ）に対し、短手方向（ＤＳ）の個々の 粘着剤層の間隔が、長手方向（ＤＬ）の個々の粘着剤層の間隔に対して広いという形態（ ＷＳ）を有し、この形態（ＷＳ）において、支持シート部分（ＳＳ）を剥した部分と、剥 していない部分との境界上の、任意の紙面（ＴＰ）と粘着面（ＡＳ）との間の接触部分（ ＬＣ）は、意図的に、粘着面（ＡＳ）を剥す方向（ＤＲ）が、前述の長手方向（ＤＬ）に 対して、斜めである場合に、前述の形態（ＥＳ）のときの、接触部分（ＬＣ）に比べて、 少なくなり、任意の紙面（ＴＰ）から、支持シート部分（ＳＳ）を、剥す力を弱くでき、 剥しやすくなるという、特徴を有する携帯用消しゴム。 In claim 2, the adhesive layer of the adhesive surface (AS) of the support sheet portion (SS) has a form in which a plurality of adhesive layers are formed intermittently on the XY plane, and the distance between the individual adhesive layers in the lateral direction (DS) and the longitudinal direction (DL ) is equal to that of the form (ES), the distance between the individual adhesive layers in the lateral direction (DS) is wider than the distance between the individual adhesive layers in the longitudinal direction (DL), and in this form (WS) , a contact portion ( When the direction (DR) in which the adhesive surface (AS) is peeled off is intentionally oblique to the longitudinal direction (DL), the contact portion (LC ) becomes smaller than the contact portion (LC) in the aforementioned form (ES) , and the force required to peel the support sheet portion (SS) from any paper surface (TP) can be weakened, making it easier to peel off. This portable eraser has the characteristic that the contact portion (LC) becomes smaller than the contact portion (LC) in the aforementioned form (ES), making it easier to peel off . 請求項３において、前述の、支持シート部分（ＳＳ）の、長手方向（ＤＬ）の一端と、 支持版部分（ＳＵ）と、Ｚ方向に対して、重なり部分（ＬＶ２）を有し、任意の紙面（Ｔ Ｐ）から、支持シート部分（ＳＳ）を、剥がす力が、重なり部分（ＬＶ２）に、加わるこ とにより、この、剥がす力による、支持シート部分（ＳＳ）の破れに対する強度が、向上 するという、特徴を有する携帯用消しゴム。 In claim 3, the portable eraser has the feature that one end of the support sheet portion (SS) in the longitudinal direction (DL) and the support plate portion (SU) overlap with each other in the Z direction, and when a force to peel the support sheet portion (SS) from any paper surface (TP) is applied to the overlapping portion (LV2) , the strength of the support sheet portion (SS) against tearing due to this peeling force is improved . 請求項１と、請求項２において、支持版部分（ＳＵ）の、側面（ＳＷ１）と、側面（ＳＷ２）と、底板（ＳＢ）が、削除される形態を有し、請求項１に示す、重なり部分（ＬＶ１） に、接着剤層（ＡＳ２）を有し、支持版部分（ＳＵ）と消しゴム（ＥＲ）の上面とが、接着剤層（ＡＳ２）で、接合される形態を有する携帯用消しゴム。 In claims 1 and 2, the side (SW1), side (SW2) and bottom plate (SB) of the support plate portion (SU) are deleted, and the overlapping portion (LV1) shown in claim 1 has an adhesive layer (AS2), and the support plate portion (SU) and the top surface of the eraser (ER) are joined by the adhesive layer (AS2) .
