Description

ASSEMBLY STRUCTURE OF RE-DEPENDABLE PROTECTIVE PANEL AND MOUNTING SHEET USING THE SAME TECHNICAL FIELD The present invention relates to a mounting structure of a re-peelable protective panel, which can mount a protective panel for use in a display window of an electronic apparatus on an exhibitor in such a way as to be removable, and also refers to a protective sheet used for such a mounting structure.

BACKGROUND OF THE INVENTION With respect to a cover used for an electronic device, such as a cell phone and a smartphone, those having a flat configuration, in which a front cover 107 and rear cover 109, made of a synthetic resin, combined together, have been generally used, and a protective panel 101 fits within the surface of the front face cover 107, so as to protect a liquid crystal display window therefrom see FIG. ). Conventionally, various modifications have been proposed in the protective panel 101. For example, Patent Document 1 has described a method in which, in order to solve the problem that the liquid crystal display is hardly discernible in a room or illuminated exteriors, due to reflection, a protective panel 101 is constituted by combining a? / 4 plate, a polarization plate and a transparent protective plate with each other. Also, this Patent Document has also described arrangements in which an additional function is imparted to the outermost surface of the protective panel 101, by preparing the transparent protective plate as a touch panel or by bonding a hard coating film or a film. from ba to reflection there. In recent years, in response to demands for more elegant electronic devices, a decorative product, such as a fringe, shown in Figure 8, has been formed on the protective panel 101 through a print. In contrast to the protective panel 101, which is supported and secured on the peripheral edge of the opening section 107c in the front face cover 107, the display 106 is attached to the upper face of the circuit substrate 108, placed inside the cover 107 of the front face and the cover 109 of the rear face; therefore, there is a distance of 0.1 to 3 mm between the back face of the protective panel 101 and the surface of the display 106. For this reason, from the viewpoint of the preventive effects of reflection, when mounting the protective panel 101 on the 106 exhibit, which. has the liquid crystal exposure window, it is preferable to join the two members together, on all their faces, within the viewing area of the display 106, in order to eliminate the air layer. However, in the case when the bonding process between the protective panel 101 and the display 106 is carried out by using only the clear adhesive layer of an acrylic adhesive agent or the like, problems arise when, due to the mixed powder or a Deviation of position in the assembly, the protective panel 101 needs to be detached and separated and this assembly process is again carried out (hereinafter, this process is referred to as a "repair process"). In other words, in an attempt to detach and separate the protective panel 101, since the transparent adhesive layer is firmly attached to both the side of the protective panel 101, and to the side of the merchandiser 106 in the same manner, the adhesive layer transparent is a separate inner layer to remain on the side of the protective panel 101, as well as on the side of the merchandiser 106, respectively, or a portion of the transparent adhesive layer will be extended to cause an irregular film thickness, with the result that it becomes difficult or impossible to carry out the repair process.

In order to solve the problem, mentioned above, with the repair process, a method for mounting the protective panel 101 on a display 106 by the use of a re-peelable mounting sheet has been proposed, and Patent Document 2 has described a process in which a panel Touch is an example of the protective panel 101, is mounted on a display 106 by using a re-detachable sheet 103 on one side. In other words, a transparent mounting sheet (sheet 102 re-peelable on one side) constituted by a plastic film core member, such as a layer of acrylic adhesive, formed on one of the faces of the core member, a first side of treatment, formed by the first treatment of the other face of the core member, and a silicone rubber sheet, which is laminated on the first treatment face, to form a re-peelable face, and the adhesive face of the sheet Mounting on the side of acrylic adhesive layer is attached to the back side of the transparent touch panel as an example of the protective panel 101, with the adhesive side of the mounting sheet on the side of the silicone rubber sheet, attached to the surface of the dispenser 106, so that this touch panel is mounted on the surface of the merchandiser 106 in a manner so as to be removable. When carrying out the repair process, this mounting sheet (re-detachable sheet 103 on one side) comes off cleanly on the side of the silicone rubber sheet in most cases, and the mounting sheet it is hardly separated.

Statement of the Invention Problems to be Resolved by the Invention However, the means used to assemble a touch panel, described in Patent Document 2, has the following problems. In other words, when assembling a cover 107 of the front face, having a protective panel 101, a circuit substrate 108, having a display 106 and the like, and a rear face cover 109, the distance between the rear face of the protective panel 101 and the surface of the display 106 tends to become different from that which has been designated, easily resulting in an error. In contrast, the sheet 102 of a re-peelable side, described in Patent Document 2, is poor in its cushioning property. Accordingly, when the distance between the back face of the protective panel 101 and the surface of the display 106 is shorter than the designated distance, the front face of the protective panel 101 tends to project from the cover. 107 of front face (see Figures 6A and 6B), or tends to be deformed in a convex configuration. In contrast, when the distance between the back face of the protective panel 101 and the surface of the exhibitor 106 is greater than the designated distance, the protective panel 101 is not sufficiently bonded to a re-peelable face of the re-peelable sheet 102 of a side, and it has to cause a high portion (see Figures 7a and 7B). Also, since the re-peelable sheet 102 on one side, described in Patent Document 2, is poor in its cushioning property, it is difficult to apply a pressure to attach the back face of the protective panel 101 to the surface of the display 106 appropriately, in a manner so as to produce bubbles gradually from the final position, resulting in a difficulty in removing these bubbles adequately. Although no bubble remains when the bonding process is carried out, in a reduced pressure atmosphere, this process requires a special installation. Therefore, in order to solve the aforementioned problems, an object of the present invention is to provide a mounting structure of a re-releasable protective panel in which, when assembling, the distance errors between the rear face of a protective panel and the surface of the merchandiser are absorbed so that a bonding process, free of bubbles, is achieved without the need to use a special installation, and a mounting sheet for use in such a mounting structure.

Means for solving the Problem In order to achieve the aforementioned objective, the present invention is provided with the following structure. In achieving these and other aspects, according to a first aspect of the present invention, there is provided a transparent mounting sheet, comprising: a re-peelable sheet on one side, comprising a core member of a plastic film. a sheet of silicone rubber, or a sheet of urethane rubber, which is laminated on a first surface treated by a surface of the core member, which has been subjected to a first treatment and capable of being brought into contact with one of a protective panel for an exposure window of an electronic apparatus and an exhibitor, and a layer of acrylic adhesive agent, which is laminated on the other surface of the core member; and a gel sheet, of at least one of the surfaces which is sequentially bonded to the layer of the acrylic adhesive agent.

According to a second aspect of the present invention, there is provided the transparent mounting sheet, as defined in the first aspect, in which the re-peelable sheet on one side joins only a first surface of the gel sheet, while the layer of the acrylic adhesive agent is laminated on the other surface of the gel sheet. According to a third aspect of the present invention, the transparent mounting sheet is provided, as defined in the first or second aspect, in which one of the outermost faces of the mounting sheet has a detachment force that is greater than the detachment force of the other, outermost face. According to a fourth aspect of the present invention, there is provided a transparent mounting sheet, as defined in any of the first to the third aspects, wherein the core member has a thickness of 12 μm or more. According to a fifth aspect of the present invention, the transparent mounting sheet is provided, as defined in any of the first to the third aspects, wherein a thickness of the silicone rubber sheet or the urethane rubber sheet, forming the re-releasable face of the mounting sheet is set to a range of 20 to 100 μm.

According to a sixth aspect of the present invention, the transparent mounting sheet is provided, as defined in any of the first to the third aspects, in which the layer of the acrylic adhesive agent has a thickness of 10 μm or more. According to a seventh aspect of the present invention, a mounting structure of a re-peelable protective panel is provided, wherein the protective panel for the exposure window of the electronic apparatus is mounted on a surface of the display. in a manner that is re-peelable, using the transparent mounting sheet, as defined in any of the first to the sixth aspects.

Effects of the Invention The present invention, which has the structure mentioned above, allows the following effects to be realized. In other words, the protective panel for an exposure window of the electronic apparatus is mounted on the surface of the merchandiser in a manner that is re-peelable through the transparent mounting sheet, formed by adding the gel sheet, which has a superior cushioning property to the removable side of one side; therefore, by preliminarily taking a range of compression of the gel sheet under consideration, the mounting sheet that is formed thicker than a distance designed between the back face of the protective panel and the surface of the merchandiser is used in a way that, even when assembling, any error occurs in the distance between the back face of the protective panel and the merchandiser surface on either side more or less, with respect to the designed distance (a cover that is shorter or longer than the distance designed), the corresponding error can be absorbed through the gel sheet. Accordingly, it is possible to prevent the front face of the protective panel from projecting out of the front face cover or from deforming into a convex configuration, and also preventing the mounting sheet from being raised from the re-releasable face, without being attached . Also, since the protective panel for an exposure window of the electronic apparatus is mounted on the surface of the merchandiser in a manner so as to be removable through the transparent mounting hoop formed by adding the gel sheet, having a superior cushioning property, to the re-peelable sheet on one side, a pressure may be applied by the fingers or the like, from the end portion of the mounting sheet, in a manner so as to gradually produce bubbles, in the union of the back face of the protective panel to the surface of the merchandiser; therefore, it is possible to carry out a bubble-free bonding process, without the need to use a special installation.

Referring to the figures, the following description will discuss embodiments of the present invention in detail.

Figure 1 is a cross-sectional view showing a mounting structure of a re-peelable protective panel, according to the first embodiment of the present invention. In this figure, the reference numeral 1 indicates a transparent protective panel, 2 indicates a transparent mounting sheet, 3 indicates a re-detachable sheet on one side, transparent, 3a indicates a transparent core member. 3b indicates a primary treatment surface, 3c indicates a transparent silicone rubber sheet, 3d indicates a layer of acrylic adhesive and 4 indicates a transparent gel sheet, respectively. With respect to a transparent touch panel ÍA, which serves as an example of the protective panel 1 of the exposure window of an electronic apparatus, for example as shown in Figure 9, a structure, which is provided with a main body. of a protective panel in plate configuration, having an upper surface on which a transparent lower electrode lid is formed, a transparent resin film Ia, having a lower surface, on which a transparent upper electrode 11b is formed, and a transparent resin cover film, with a decorative layer llh. having a transparent window portion, which is formed on at least one of its surfaces, is proposed. The main body llc of the protective panel and the transparent resin film are joined together on peripheral portions by using a double-sided tape II, with an air layer 22g being located between the upper and lower electrodes, 11b, lid, with the upper electrode 11b facing the lower electrode lid, so that the transparent resin cover film may be attached to the upper surface of the transparent resin film lia. Also, in each of the main body of the protective panel and the transparent resin film, a predetermined pattern circuit, including busbars and guide lines, is formed on the same surface as each of the lower transparent electrode lid and the transparent upper electrode 11b, and projects to the outside, for example, from the side of the transparent touch panel IA, through a film connector. Alternatively, the circuit projects outwardly from the rear surface of the touch transparent panel IA through a transverse hole formed in the main body llc of the protective panel. The portion of the transparent window of the decorative layer llh is constructed by a transparent adhesive agent llf for bonding the film of transparent resin cover film to the upper surface of the transparent resin film lia. A plurality of point spacers 11m are formed on the surface of either the upper transparent electrode 11b and the lower transparent electrode lid, so that a gap between the upper transparent electrode 11b and the lower transparent electrode ld is maintained by the spacers 11m point . With respect to the material for the main body llc of the protective panel, a material, which is superior in transparency and can protect a display,. such as a liquid crystal panel, and an organic EL damage panel is used. Examples of the material include resins for general use, such as polystyrene resin, polyolefin resin, ABS queen, AS resin, acrylic resin or A resin. Also, a general purpose engineering resin or a higher engineering resin may be used. Here, with respect to the main body llc of the protective panel, the lower transparent electrode lid can be formed through a transparent resin film, which is different from the clear resin film lia and is disposed directly on the upper surface of the main body llc of the protective panel. The thickness of the main body llc of the protective panel is preferably about 0.4 mm or greater. With regard to the material for transparent resin film, examples thereof include engineering plastics, such as those of polycarbonate, polyamide and polyether ketone type, and ream films, such as those of acrylic type, polyethylene terephthalate and polybutylene terephthalate. Each of the lower transparent electrode lid and the upper transparent electrode 11b, are made of a transparent conductive film. With respect to the material for the transparent conductive film, examples thereof include metal oxides, such as tin oxide, indium oxide, antimony oxide, zinc oxide, cadmium oxide or ITO, and metals, such as Gold, silver, copper, tin, nickel, aluminum and palladium, or a thin film of a conductive polyether can be used. With respect to the method of forming the lower transparent electrode lid and the upper transparent electrode 11b, after the conductive coating films have been formed on all the surfaces of the main body of the protective panel and the transparent resin film, using a method, such as a vacuum deposition method, an electronic deposition method, an ion plating method, a CVG method or a roller coating method, unnecessary portions are chemically treated and removed. With respect to the material for the circuit, metals, such as gold, silver, copper and nickel, or a paste having a conductive property, such as carbon, are used. The method for its formation includes: a printing method, such as a screen printing method, an offset printing method, an engraving printing method or a flexographic printing method; photo-resistive methods or a brush painting method. The end portion of the film connector is inserted between the main body llc of the protective panel, and the transparent resin film Ia and connected to the outlet and the circuit through a contact joining process. Here, when a trimming portion is formed in the main body llc of the protective panel, the film connector is more easily bent and directed to the back surface. With respect to the material for the transparent ream cover film, in the same manner as the transparent resin film, engineering plastics, such as those of polycarbonate, polyamide and polyether ketone type, and resin films, such such as those of acrylic type, polyethylene terephthalate, and polyethylene terephthalate, can be used. The decorative layer llh, which has the transparent window portion, is formed on at least one of the surfaces of the cover film of the transparent resin, and this layer IIh is placed on the upper side of the film. of transparent ream on which the transparent upper electrode 11b has been formed. One portion, covered with the decorative layer llh, forms a decorative portion 11b of the protective panel 1, and the other portion, which is not covered with the decorative layer llh, forms the transparent window portion (see Figure 4). In the cover of the protective panel 1, the decorative layer llh is normally formed as a printed layer. With respect to the material for the printed layer, a color ink, which uses resin, such as polyvinyl chloride resin, polyamide resin, polyester ream, polyacrylic resin, polyurethane ream, polyvinyl acetal resin, polyester-urethane ream, cellulose ester ream, or alkyd resin, as a binder and contains a pigment or a dye having an appropriate color as a colorant,. it is preferably used. With respect to the method of forming the printed layer, a normal printing method, such as an offset printing method, an engraving printing method, or a screen printing method,. They can be used. The printing layer can be formed over the entire portion, or it can be formed partially, depending on the desired decoration to be expressed. Here, the decorative layer llh can be prepared as a layer of thin metal film or a combined layer between the printing layer and a thin film of metal. The thin metal film that is used to apply metallic gloss as the decorative layer llh,. it is formed using a vacuum vapor deposition method, an electronic deposit method, an ion plating method or a plating method. In this case, the metal, such as aluminum, nickel, gold, platinum, chromium, iron, copper, tin, indium, silver, titanium, lead or zinc; or an alloy or a compound thereof, can be used, depending on the metallic gloss color that is conveniently expressed. The thin film metal layer is partially formed in the normal way. Also, in forming the thin metal film, a pre-anchor layer and a post-anchor layer can be placed in order to improve adhesion to the other layer. Likewise, the decorative layer lb can be formed on any of the surfaces of the transparent ream cover film, when formed as a lower surface layer, this layer can be protected by a transparent film of the ream cover. to pressing forces by fingers, feathers, or the like. The foregoing description has exemplified the panel that attaches to the front face of a main body llc of the protective panel, with a touch input function and which is a touch honeycomb A that serves as an example of the protective panel 1; however, the protective panel 1 does not intend to be limited by the structure mentioned above, which has the function of touch entry, and any other protective panel, for example, a panel that is composed of only a single transparent resin board or glass plate) known in the art, may be used. Also, different from the structure where after the protective panel 1, and the front face cover 7 are manufactured separately, the protective panel 1 is adapted to the surface of the cover 7 of the front face, as shown in Figure 4, as the protective panel 1 of the sheet 2, for assembly, according to a first embodiment of the present invention, a protective panel 71 may have a structure that forms a portion of the cover 7 of the front face, as shown in FIG. Figure 5. In other words, different from the structure in which the protective panel 1, which has been molded in a separate manner from the cover 7 of the front face and then adapted to the cover 7 of the front face, the The protective panel 71 can be molded as an integral part together with the cover 7 of the front face. The exhibition 6 represents a display of an electronic equipment input device (more specifically, a display such as an LCD or organic EELD) that includes a display of portable electronic equipment, such as a portable telephone, smart phone, portable gaming device , personal notebook computer, PDA (Personal Digital Assistant), car navigation, digital camera, video camera or equipment for service communications: and a personal computer monitor. The transparent touch panel ÍA is mounted on the surface of the merchandiser 5 and, subsequently, presses a display surface of the transparent touch panel ÍA with a pen, a finger, or the like, while viewing the display of the merchandiser 6 carrying the electrode upper 11b and the lower electrode lid in mutual contact, so that several input operations as an input device are carried out. The following description will discuss a mounting process of the protective panel 1, in which the mounting sheet 2, containing the gel ho a 4, having a cushioning property, which is a feature of the first embodiment of the present invention , is used in the display case 6. A mounting structure of a re-releasable protective panel 1, according to the first embodiment, shown in Figure 1, is designed so that a re-detachable sheet 3 on one side, is It consists of a core member 3a of a transparent plastic film, a silicone rubber sheet 3c, which is laminated on the first treated face 3b. which has been formed on one of the faces of the core member 3a through the first treatment to build an adhesive surface on a display side and a layer of 3d adhesive which is successfully laminated on the other side of the core member. . Furthermore, in the assembly structure, the re-detachable sheet 3, on one side, is joined to at least one of the faces of the gel sheet 4 by the acrylic adhesive layer 3d, so as to form the transparent mounting sheet 2 . The protective panel 1 is mounted on the surface of the merchandiser 6 with the mounting sheet 2, to form the mounting structure by the construction so that the other surface of the gel sheet 4 builds an adhesive surface on the side of the panel transparent touch The gel sheet 4 of the mounting sheet 2, constructed in such a way as to be attached to the entire face of the viewing area of the back face of the protective panel 1 (in other words, the face on the side of the panel display 6) protector 1 in this first embodiment (the lower surface of Figure 1)) and the silicone rubber sheet 3c of the removable sheet 3, on one side, of the mounting sheet 2, is brought into contact with the full surface of the display 6. The plastic film, which serves as the core member 3a, is used to support the 3d layer of the acrylic adhesive agent and the sheet 3c of slicona rubber. Likewise, since the first treatment face 3b is formed on the other surface of the plastic film, that plastic film is firmly attached to the sheet 3c of silicone rubber. Provided that the mounting sheet 2 is provided on a rear surface of a large-sized panel (eg, a 500 mm by 500 mm panel from which transparent touch panels ÍA, each measuring 100 mm by 100 mm , can be die cut) from which a member of transparent touch panels ÍA are to be obtained and are then stamped together with each touch transparent panel ia, with the provision that the first treated surface 3b on the core member, ensures a firm adhesion of the core member 3a to the silicone rubber sheet 3c, so that the silicone rubber sheet 3c of the mounting sheet 2 can be restricted from projecting from a circumference of each touch transparent panel, obtained by the die-cut With respect to the core member 3a, so as not to cause degradation in the visibility of the merchandiser 6, a material, which is of superior transparency and has a total light transmission capacity of 8% or more (JIS-K7105-1981) and has a value of impalement of 3% or less (JIS-K7105-1981) is preferably used. Also, with respect to the core member 3a, for example, a film that is transparent and has an optically isotropic property, such as a PET film (Polyethylene Terephthalate), PC (Polycarbonate), TAC (Triacetyl-Cellulose) PES ( Polys ter-Sulfone can preferably be used Here, the thickness of the plastic film forming the core material 3a is preferably set at 12 μm or more.The thickness less than 12 μm tends to cause ripples in the core member 3a when forming the coating film, making it difficult to uniformly control said thickness; therefore, the surface to form the outer face of the silicone rubber sheet 3c (in other words, the surface on the side of the merchandiser 6 of the protective panel 1 in the first embodiment) has irregularities, and tends to cause bubbles due mixed air at the time of mounting the transparent touch panel 1. The thickness of the plastic film forming the core material 3a is preferably set to 75 μm or less. Since the re-detachable sheet 3, on one side, which includes the core member 3a, joins the flexible gel ho a 4, the thickness greater than 75 μm of the core material 3a tends to damage its flexibility function , so the removable ho, 3, on one side, does not fit on the gel sheet 4. More specifically, as a numerical example, the thickness of the core member 3a is 38 μm.

In general, the first treatment, mentioned above, is a treatment in which, in order to improve the adhesion between the base member and the coating agent, an intermediate agent, which is very compatible with the two members, is applied to the base member In the broadest sense of the word, the first treatment refers to an easy bonding treatment, which includes a treatment used to increase adhesion by forming irregularities in the surface of the base member to increase the surface area and a treatment used to increase the adhesion by conducting a treatment that modifies the surface through a corona process or the like In the mounting sheet 2 of the aforementioned first embodiment of the present invention, the sheet of the silicone rubber 3c is firmly attached to the core member 3a through the first treatment so that, upon detachment of the touch panel A, this detachment may not take place between the core member 3a and the ho a 3c of the silicone rubber, or in the die-cut, the sheet 3c silicone rubber may not be displaced between the core member 3a and the silicone rubber sheet 3c so as not to project the silicone rubber sheet 3c from the circumference of the silicone rubber sheet 3c. Transparent touch. The acrylic adhesive 3d layer, which is formed by applying an adhesive agent, generally used for adhesive tapes or the like, is designed to exert a large adhesive force which is not only resistant to a separation force, which is exerted in the perpendicular direction to the forming face of the acrylic adhesive layer 3d, between the acrylic adhesive layer 3c and a gel sheet 4 and a displacement bale that is exerted in a lateral direction, along the forming face of the acrylic adhesive layer 3c, but also resistant even to the separation force that is exerted, in order to separate the re-detachable sheet 3, on one side, from the gel sheet 4 to which the sheet 3 re-detachable, on one side has been removed. joined through the acrylic adhesive 3d layer in a manner to detach the re-peelable sheet 3 from one side from the end portion, so that the re-peelable sheet on one side and the gel sheet 4 do not easily come off re yes Here, the thickness of the acrylic adhesive 3d layer is preferably set at 10 μm or more. Thickness less than 10 μm tends to unfavorably cause elevated portions to be joined, even in an attempt to bond them to the gel 4 ho. A thickness of the 3d layer of the acrylic adhesive people is preferably in the range of 10 to 50 μm. The thickness of less than 10 μm weakens the adhesive force and makes it difficult to control the mounting sheet 1 which will be left on the side of the touch transparent panel ia or on the side of the merchandiser 6 in the repair. The thickness greater than 50 μm makes the adhesion outside too large, on the contrary, and makes it difficult to remove the air bubbles even if a defoaming process is performed on the air bubbles that occurs or has occurred between the 3d layer of the acrylic adhesive agent and the gel layer 4 in the manufacture of the mounting sheet 2, for example, even if the mounting sheet 2 is pressed with a roller or the like, while the fold is rounded, so that the air bubbles they are expelled gradually from one end or even by the placement of an atmosphere of reduced pressure. The silicone rubber sheet 3c is highly resistant to a separation force exerted in the direction perpendicular to the laying face of the silicone rubber sheet (first treatment face 3b) and a displacement force exerted in a lateral direction to along the laying face, between the sheet 3c of silicone rubber and an adhesion object; however, when a separation force, which is exerted in order to separate the mounting sheet 2 from the adhesion object to which the mounting sheet 2 has been attached, through the ho 3c of silicone rubber in a way so as to detach the mounting sheet 2 from the end portion, it is exerted, the mounting sheet 2 and the adhesion object are easily detached from one another. With respect to the material for the silicone rubber sheet 3c, a silicone rubber sheet to be used as a shock absorbing agent or the like, can preferably be used. Also, with respect to the silicone rubber sheet 3c, for example, a mixture between the silicone rubber and the silicone resin is formed from an ink using a solvent, and a material to which this has been coated, and then Interlacing by using heat at the time of drying, can also be used. Here, the sheet 3c of silicone rubber, mentioned above, does not diminish its strength of assurance, even after the processes of union and detachment at any moment. The thickness of the silicone rubber sheet 3c forming the re-releasable face of the mounting sheet is preferably established in a range of 20 to 100 μm. The thickness of this sheet 3c of silicone rubber exceeding 100 μm, makes the adhesive force too large, with the result that when detaching from the protective sheet 1, it becomes difficult to separate the protective panel 1 on the face of the ho a mounting 2 on the side of the silicone rubber sheet 3c. Likewise, in the case where the thickness of the silicone rubber sheet 3c is less than 20 μm, even in the attempt to join the silicone rubber sheet 3c to an adhesion object, such as an exhibitor 7, the portions Elevations without being united tend to be generated, with the result that it is too easy (in other words, a level beyond the necessary) the detachment and separation. The gel jacket 4 is used to impart the cushioning property to the mounting sheet 2. The gel sheet 4 is obtained by molding a transparent, high molecular weight adhesive agent in a gel sheet configuration. With respect to the high molecular weight adhesive agent, for example, high molecular weight materials based on acrylic, urethane-based or natural base can be used. Here, the gel sheet 4 is used to prevent separation of the gel sheet 4 from the protective panel 1, in a state of normal use, after the assembly process. Likewise, the gel sheet 4, made of a high molecular weight adhesive agent, also serves as a shock absorbing agent, due to the elastic property inherent in the gel, in order to protect the display 6 from various impacts and deformations. The thickness of the gel sheet 4 is constructed to be larger than a designated distance, so that the gel sheet 4 can be compressed to a certain extent, when the protective panel 1 for the exposure window of the electronic apparatus is mounted on the surface of the merchandiser 6, in a manner that is re-peelable. Consequently, the total thickness of the mounting sheet 2 is greater than the designed distance between the back face of the protective panel 1 and the surface of the merchandiser 6, and thus, even when, when assembling, any error in the distance between the face occurs. of the protective panel 1 and the surface of the merchandiser 6 on the minor side with respect to the designated distance (in a case shorter than the designated distance) and the greater side with respect to the designated distance (in a case greater than the distance designated), the corresponding error can be absorbed through the gel sheet 4. The mounting sheet 2 has such excellent function as described above. The upper limit of the thickness of the gel sheet 4 can be determined arbitrarily according to the use. With taking into consideration the actual use situation, the thickness of the gel sheet 4 is preferably 10 mm. The lower limit of the thickness of the gel sheet 4 is 0.2 mm. The reason is that the lower limit of the thickness of an existing gel sheet is 0.2 mm and that the thickness less than 0.2 mm of the gel sheet damages its cushioning function and this gel sheet tends to break due to too small thickness , it results unfavorably in difficulties in the assembly. In a case where the gel sheet 4 is compressed so as to absorb any error occurring in the designated distance and thus a part of the gel sheet 4 projects in the transverse direction, it is necessary to define a space to allow the projection of the gel sheet 4 into the circumference of the gel sheet 4. As such a space, it is preferable that a space having a distance 6 equal to or greater than 50% of the thickness of the gel sheet 4 in a direction perpendicular to the direction of thickness of the ho a 4 gel is defined over the entire circumference of sheet 4 of gel. (For example, it is preferable that a space having a distance G of 5 mm or more, when the thickness of the gel sheet 4 is 10 mm is defined in the total circumference of the sheet 4) of gel. In a space where such a space is defined (at such a circumference of the gel sheet 4, although the gel sheet 4 is compressed to project a part of the gel sheet 4 in the transverse direction, the projected portion of the sheet 4 of gel is accommodated in the space having the distance corresponding to the thickness of the gel sheet 4 in the thickness direction of the gel sheet 4, and the projected part does not reach the layer (s) adjacent to it. the gel length 4. Thus, such a space can be safely prevented from causing adverse effects on the visibility of the display 6 and the operability of the entrance of the touch panel 14. In contrast, in the case where such space does not it is defined in the circumference of the gel sheet 4, although a part of the gel sheet 4 tends to project in the transverse direction, the gel sheet 4 can be projected and thus the thickness of a part of the gel sheet 4 it becomes, adversely, larger than the thickness of its other part. r of the gel sheet 4 becomes irregular, possibly resulting in adverse effects on the visibility of the display 6 and the input operability of the touch panel. Alternatively, although a part of the gel sheet 4 projects in the transverse direction from the gel sheet 4, the projected part reaches, immediately and adversely, the layer (s) adjacent to the gel sheet 4 to enter in the viewing area of the merchandiser 6, possibly resulting in the cause of adverse effects on the visibility of the merchandiser 6 and the operability of the touch panel input. In order to merely prevent such problems, as described above, the space having the distance G of 50% or more of the thickness of the gel sheet 4 is preferably defined in the total circumference of the gel sheet 4. As more specific examples, where the spaces are defined, Figures 14 to 15 show cross-sectional views, showing three examples of mounting structures of the re-detachable protective panels, according to any of the first to the fifth modalities of the present invention, in which the re-detachable protective panel and the display 6 are assembled together. Figure 13 shows an example where the space (space 50) is defined between the mounting sheet 2 and the front face cover 7. That is, in Figure 13, the protective panel 1 (alternatively, the touch panel IAA) and the mounting sheet 2 have almost the same configuration and size, and the periphery of the surface of the protective panel 1 (alternatively, the panel Touch screen) is covered with an opening forming portion 7a to form the transparent window portion of the cover 7 of the front face. Between an interval of the main body of the cover of the front face, the inner wall 7b closes to the opening forming portion 7a and the outer side surface of the gel sheet 4 of the mounting sheet 2, the space 50 for allowing the projection of the gel sheet 4 having the distance G is defined. Figure 14 shows an example where the space is defined in the mounting sheet 2 itself (in other words, in order to define the space in the mounting sheet 2, this mounting sheet 2 is smaller than the protective panel 1 ( alternatively, the touch panel ÍA). That is, in Figure 14, the mounting sheet 2 is smaller than the protective panel 1 (alternatively, the touch panel ia) and the periphery of the surface of the protection panel 1 (alternatively, the touch panel ia) is covered with the opening forming portion 7a to form the transparent window portion of the cover 7 of front face Thus, between a main body of the front face cover, the inner wall 7b closes the opening forming portion 7a and the outer side surface of the gel sheet 4 of the mounting sheet 2 and between the protective panel 1 (alternatively the touch panel IA) and the display 6, the space 50 to allow the projection of the sheet 4 of the gel, which has distance G is defined. Figure 15 shows an example where the space is defined between the mounting sheet 2 and the cover 7 of the front face, when the surface of the protective panel 1 (alternatively, the touch panel AA) and the surface of the first cover 7 of the front face are flush with each other. That is, in Figure 15, the mounting sheet 2 is smaller than the protective panel 1, 71 (alternatively, the touch panel IA) and the protective panel 1 (alternatively, the touch panel IA) is adapted in a portion 7d of aperture formation, to form the transparent window portion of the cover 7 of the front face (alternatively, the protective panel 71 and the front face case 7 are integrally molded together), the surface of the protective panel 1 , 71 (alternatively, the touch panel IA and the surface of the front face cover 7 are flush with each other.Thus, between the main body of the cover of the front face, the inner wall 7c closes the portion 7 for opening formation and the outer side surface of the gel sheet 4 of the mounting sheet 2 and between the protective panel 1, 71 (alternatively, the touch panel IAA) and the display 6, the space 50 to allow the projection of a sheet 4 of gel, which has the Elderly G was defined. Furthermore, in Figures 14 and 15, when the mounting sheet 2 is smaller than the protective panel 1, 71 (alternatively, the touch panel IAA) the size of the mounting sheet 2 is larger than the viewing area (visible area) of the display 5, so that no problems are caused. Here, of the outermost structure of the mounting sheet 2 (ie, the outer surface of the gel sheet 4 and the outer surface of the silicone rubber sheet 3c), the peeling force of one of the surfaces is it is greater than the detachment force of the other, so it is always possible to cause separation on the same side of the mounting sheet 2. For example, the detachment force of the outer surface of the gel sheet 4 is greater than the detachment force of the outer surface of the silicone rubber sheet 3c, so it is always possible to cause separation on the side between the 3c of silicone rubber and the exhibitor 6. Conversely, the detachment force of the external surface of the silicone rubber sheet 3c is greater than that of the external surface of the gel sheet 4, so that it is always possible to cause separation on the side between the gel sheet 4 and the protective panel 1. Likewise, in the coating processes, during the manufacturing process of the mounting sheet 2, that is to say in coating or coating agent. coating at the time of the first treatment, in coating an acrylic adhesive agent at the time of formation of the 3d layer of acrylic adhesive, as in the coating in forming the sheet 3c of silicone rubber, a method of coating General method, such as an engraving coating method or a die coating method can be used. According to a first embodiment, in the repair, the mounting sheet 2 is usually detached and separated in a net manner from the merchandiser 6 on the side of the sheet 3c of silicone rubber, because the force of detachment from the surface The outer part of the gel sheet 4 is larger than the detachment force of the external surface of the silicone rubber sheet 3c, so that a part of the mounting sheet 2 is rarely transferred to the display 6 or a part of the sheet Assembly 2 is separated from its other part. Also, according to a first embodiment, the protective panel 1 for an exposure window of an electronic device is mounted on the surface of the merchandiser 6 in a manner so as to be removable through the transparent mounting sheet 2, formed by adding the gel sheet 4, which has a superior cushioning property to the re-detachable sheet 3 on one side and, therefore, by preliminarily taking a compression margin from the gel sheet 4 under consideration, sheet 3 of assembly, which is formed thicker than a designated distance between the rear face of the protection panel 1 and the surface of the merchandiser 6 is used, so that, even when assembling, any error in the distance between the rear face occurs. of the protective panel 1 and the surface of the merchandiser 6 on the minor side with respect to the designated distance (in a case shorter than the designated distance) and the greater side with respect to the designated distance (in one more space) larger than the designated distance), the corresponding error can be absorbed through the gel sheet 4. Consequently, it is possible to prevent the protective front face 1 from projecting out of the front face cover 7 or from deforming into a convex configuration and also preventing the mounting sheet 2 from being raised from the re-releasable face without being attached. Also, according to a first embodiment, since the protective panel 1 for an exposure window of an electronic apparatus is assembled on the surface of the merchandiser 6 in a manner to be re-peelable through the transparent mounting sheet 2 formed adding sheet 4 of gel that has a superior cushioning property to the sheet 3 re-detachable from one side, pressure can be applied by fingers or the like, from the end portion of the sheet 4 of gel in a manner to thereby gradually produce bubbles, at the junction of the back face of the protective panel 1 to the surface of the merchandiser 6, therefore, it is possible to carry out the bubble-free bonding process, without the need to use a special installation. With reference to Figure 1, the assembly apparatus of the first embodiment has been explained; however, the present invention is not limited to this embodiment, and may be carried out in several other ways. For example, in a mounting structure of a re-peelable protective panel, according to a second embodiment of the present invention, as shown in Figure 2, a transparent mounting foil 2A, having the gel sheet 4 in which the sheets 3 re-peelable from one side (ie, first sheets 3-1 re-peelable from one side and second sheets 3-2 re-peelable from one side) are joined on both of their two sides and are use instead of transparent mounting sheet 2 of the first mode. In the mounting structure, the protective panel 1 on which the mounting sheet 2A is formed, is mounted on the surface of the merchandiser 6 so as to join the sheet 3c of the silicone rubber of the first 3-to re-peelable sheets of one side of the mounting sheet 2A over the entire face of the viewing area of the rear face of the protective panel 1 (in other words, the surface on the side of the merchandiser 6 of the protective panel 1 (the lower surface of the protective panel 1 in FIG. Figure 2) in the second embodiment and obtain the sheet 3c of silicone rubber from the second sheets 3-2 re-detachable from one side in contact with the entire surface of the merchandiser 6. In this case, it is not necessary that the sheets of silicone rubber are on the outermost faces of the leaves 3-1 and 3-2 re-detachable on one side have the same force of detachment, and making the force of detachment of a sheet 3c of silicone rubber of the faces more external than the force of contempt With the other silicone rubber sheet 3c, it is always possible to separate on the same side of the mounting sheet 2A (the outer surface side of the silicone rubber sheet 3c having the lowest release force). Also, in a mounting structure of a re-releasable protective panel 1, according to a third embodiment of the present invention, as shown in Figure 3, a transparent mounting sheet 2B having the gel ho a 4 in wherein a layer 5 of acrylic adhesive is further laminated to the unfolded surface 3 re-peelable from a side, being joined thereto is used in the placement of the transparent mounting sheet 2 of the first embodiment. In the mounting structure, the protection panel 1 on which the mounting sheet 2B is formed is mounted on the surface of the display 6 in order to join the layer 5 of the adhesive agent of the mounting sheet 2B on the entire face of the viewing area of the rear face of the protective panel 1 (in other words, the surface on the side of the merchandiser 6 of the protective panel 1 (the lower surface of the protective panel 1 in Figure 3) in the third embodiment makes the 3c of silicone rubber sheet 2B assembly this in contact with the entire surface of the exhibitor 6. With this arrangement, the adhesive forces of the surface of the sheet 4 gel without the re-detachable sheet of a side attached there, it can be improved, so that positive detachment and separation between the silicone rubber sheet 3c and the display 6, on the outermost surface of the re-peelable sheet 1 on one side, without, between the protective panel 1, is possible. and the cap to 5 of the acrylic adhesion agent is the same as that used in the 3d acrylic adhesive layer of the re-detachable sheet 3 on one side. Also, as a mounting sheet 2C, according to the fourth embodiment of the present invention, as shown in Figure 10., the mounting sheet 2 of the first embodiment of the present invention can be disposed face down to the structure of Figure 1 so that the silicone rubber sheet 3c is prepared as the adhesion face on the side of the protective panel and the gel sheet 4 was prepared as the adhesion face on the display side. In other words, the assembly can be done so that the transparent mounting sheet 2c is attached to the surface of the merchandiser 6 by its gel sheet 4 and the protective panel 1 is bonded onto the sheet 3c of silicone rubber, which is the surface of the mounting sheet 2C in the display 6. Likewise, as a 3D mounting sheet, according to a fifth embodiment of the present invention,. As shown in Figure 11, the mounting hole 2B of the third embodiment of the present invention can be disposed upside down to the structure of Figure 3, so that the silicone rubber sheet 3c is prepared as the face of adhesion on the side of the protective panel and the acrylic adhesive layer 5 is prepared as the adhesion side on the side of the merchandiser. In other words, the assembly can be performed so that the layer of acrylic adhesive 5 of the transparent mounting sheet 2D is bonded to the surface of the merchandiser 6 and the protective panel 1 is bonded onto the sheet 3 of silicone rubber of the surface of the 2D mounting sheet on the display 6.

Similarly, in the first to fifth embodiments, instead of the silicone rubber sheet 3c, a urethane rubber sheet 13c can be used to form a mounting sheet 2E. For example, as shown in Figure 12, mounting sheet 2 of Figure 9, a urethane rubber sheet 13c may be used in place of the silicone rubber sheet 3c to form a mounting sheet 2A. Since the figures of the mounting sheets use the urethane rubber sheets 12c are not different from those of the mounting sheets that use the silicone rubber sheets, representatively, only one example of a case where the rubber sheet 13c The silicone rubber used in Figure 9 is shown as Figure 12. In other figures, the silicone rubber sheets can be read as urethane rubber sheets 13c. The urethane rubber sheet 13c is highly resistant to the separation force exerted in a direction perpendicular to the disposing face of the urethane rubber sheet (first treatment face 3b) and a displacement force exerted in the lateral direction of the urethane rubber sheet. along the laying face, between the sheet 13c of urethane rubber and an adhesion object; however when a separation force, which is exerted to thus separate the mounting sheet 2 from the adhesion object to which the mounting hole 2 has been attached, through the urethane rubber sheet 13c in a manner for thus detaching the mounting sheet 2 from the end portion is exerted, the mounting sheet 2 and the adhesion object are easily detached and detached from each other. With respect to the material for the urethane rubber sheet 13c, a polyurethane-based rubber sheet will be used as a shock absorbing agent or the like, it can preferably be used. Also, as the sheet 13c of urethane rubber, for example, while the polyol and isocyanate are included as a main content, another material is added or its mixing ratio is changed to thus have various functions, such as a cushioning property, a resistance to heat, a sealing property or a resistance to shocks, in correspondence with the application, which results in obtaining a sheet based on polyurethane. Following will be explained working examples of the previous modalities.

Working Example 1 A transparent polyester film, having a thickness of 38 μm, was used as a core member, and one of its surfaces was first subjected to a surface modification treatment through the corona discharge, and a silicone rubber sheet, which has a thickness of 40 μm, was laminated there using a coating device, and on this surface, a polyester film which has been subjected to a mold release treatment, was laminated as a separator. Next, a layer of acrylic adhesive, having a thickness of 30 μm, was laminated on the other surface of the core member using a coating device, and on this surface, a polyester film, which has been subjected to a treatment of mold release, was laminated as a separator, so that a transparent, re-peelable sheet was obtained on one side, having separators formed on both surfaces. A transparent, high molecular weight adhesive based on polyurethane was formed in a gel state 1 mm thick, and separators were prepared, formed in < both of their surfaces, which carry a gel sheet, commercially available. Then, one of the separators of the gel sheet was separated, and the separator of the re-peelable sheet on one side on the side of the layer of acrylic adhesive was separated, so that the two sheets were joined together to provide a ho a montage. Next, the separator of the mounting sheet on the side of the silicone rubber sheet was separated, and the mounting sheet was attached to the entire rear face of the protective panel. Finally, the remaining separator, which is the other separator of the gel sheet, has been separated, the protective panel was attached to the entire surface of an LCD.

Working Example 2 In the same manner as in Working Example 1, two re-peelable sheets, one side, and one gel sheet, were prepared, and one of the separators of the gel sheet was separated, and the separator of the first or re-detachable, on one side, on the side of the layer of acrylic adhesive, was separated so that the two sheets were joined together. Next, the other separator of the gel sheet was separated and the separator of the second re-detachable sheet, on one side, on the side of the layer of acrylic adhesive, was separated so that the two sheets were joined together to prepare a mounting sheet. Next, the separator of the mounting sheet on the side of the silicone rubber sheet was separated, and the mounting sheet was attached to the entire rear face of the protective panel. Finally, the remaining separator, which is the other separator of the gel sheet, has been separated, the protective panel was attached to the entire surface of an LCD.

Working Example 3 A re-detachable sheet on one side, and a gel sheet, were prepared in the same manner as in Working Example 1, and one of the separators on the gel sheet was separated, and the separator the re-peelable sheet on one side, on the side of the acrylic adhesive layer, was separated so that the two sheets were joined together. Next, the other gel separator was separated, and a layer of acrylic adhesive, having a thickness of 30 μm, was laminated there using a coating device, and the polyester film which was subjected to a treatment Mold deliberation was laminated on its surface as a separate, so a mounting sheet was obtained. Next, the separator of the mounting sheet on the side of the silicone rubber sheet was separated, and the mounting sheet was attached to the entire rear face of the protective panel. Finally, the remaining separator, which is the other separator of the gel sheet, has been separated, the protective panel was attached to the entire surface of an LCD. In any of the Working Examples 1 to 3, in assembly, the distance errors between the back face of the protective panel 1 and the surface of the merchandiser 7, are absorbed by the gel sheet, so the free joining processes of Bubbles were carried out without the need for a special installation. By appropriately combining the arbitrary modalities of the various modalities, mentioned above, the effects possessed by the modalities can be produced. Although the present invention has been fully described in connection with its preferred embodiments with reference to the accompanying drawings, it will be noted that various changes and modifications are apparent to those skilled in the art. Such changes and modifications will be understood to be included within the scope of the present invention, as defined by the appended claims, unless it is mentioned that they depart from them.
