  The device case 2 has a shape and size that can be hand-held by one hand. Specifically, as shown in FIGS. 1 and 2, the front outline shape and width that can house the feeding reel 5 and the take-up reel 6 are shown. It is made into the substantially rectangular parallelepiped shape provided with. The device case 2 is made of plastic with a two-part structure comprising a case main body 7 and a cap main body 8 which are integrally formed by injection molding or the like. A head insertion opening 9 is formed, and a protective cap 10 that covers and protects the peeling head H is detachably fitted.

  The feeding reel 5 and the take-up reel 6 are rotatably mounted on the case body 7 of the apparatus case 2, and an annular rubber member 11 as a tape interlocking means is elastically wound around both of them. Both reels 5 and 6 are configured to rotate together.

  In relation to this, the device case 2 includes an opening 2b in which a part of the feeding reel 5 or the take-up reel 6 faces the outside. The opening 2b functions as an operation window for rotating the feeding reel 5 or the take-up reel 6, and constitutes a tape feeding means for manually feeding the sampling tape T from the outside of the apparatus case 2.

  Specifically, the operation window 2b is a connection opening of an operation dial 12 to be described later. In the illustrated embodiment, the operation window 2b is provided corresponding to the shaft portion 5a of the supply reel 5. Thereby, the shaft portion 5a of the supply reel 5 faces the outside of the device case 2 through the operation window 2b, and the operation dial 12 can be rotationally engaged with the shaft portion 5a as described later. The structure allows manual feeding operation.

  As shown in FIG. 2B, the sampling tape T wound around the supply reel 5 is guided to the peeling head H through guide pins 13 and 14 provided upright on the case body 7, After being folded at the leading edge Ha of the peeling head H, it is wound around the take-up reel 6 via a guide pin 15 provided upright on the case body 7.

  The peeling head H guides the sampling tape T fed from the feeding reel 5 and also peels and feeds the sampling seal S on the sampling tape T, a function for holding the sampling seal S in a temporary peeling state, and sampling A function for positioning the seal S on the mount P for collecting material sticking (see FIGS. 7D and 7E), and a function for pressure-transferring the collecting sticker S onto the paste for mounting paste P (selective function) ) And provided at the tip 2a of the device case 2.

  As shown in FIGS. 2 to 4, the specific structure of the peeling head H is formed with guide flanges 21 and 21 for guiding the running of the sampling tape T on both side edges of the head body 20, and its base portion is It is attached and fixed to the device case 2.

  The head main body 20 has a shape suitable for effectively exerting the above three (or four) functions. Specifically, the head main body 20 has a so-called pointed shape with a pointed tip to some extent, and is thus peeled off. The head H is in the form of a pointed head.

  The head main body 20 of the illustrated embodiment is a thin plate-like body having a rectangular shape slightly wider than the sampling tape T, and has a shape that is somewhat sharp when viewed from the side, that is, gradually becomes thinner toward the tip. It has a tapered cross section, more specifically, the lower side surface 2a has a tapered cross section inclined upward toward the tip.

  The head main body 20 has flat upper and lower side surfaces 20 a and 20 b that form a tape running surface, and a leading edge thereof forms a leading edge Ha of the peeling head H. This leading edge Ha turns the leading edge of the sampling tape T to exert the peeling function of the sampling seal S (see FIG. 3A), and pressurizes the sampling tape T on the mount P for collecting material sticking. For this purpose, the tip pressurizing portion Ha is in the form of a straight edge perpendicular to the tape running direction on the tape running surfaces 20a and 20b. Further, as described above, the guide flanges 21 and 21 are formed on both side edges of the head main body 20, whereby the sampling tape T is guided by the guide flanges 21 and 21 while the tape running surface 20 a. , 20b.

  The material characteristics of the head body 20 itself are desirably set in consideration of the pressurizing action of the sampling tape T by the tip pressurizing portion Ha, and may be in the form of an elastic head or a hard head depending on the purpose. Either can be adopted.

  The collection tape T is a continuous supply of the collection seal S, and a large number of pressure-sensitive adhesive collection seals S, S,... Yes.

  In the illustrated embodiment, the sampling tape T has a cross-sectional structure as shown in FIG. 5, and a large number of sampling tapes T are provided on the surface (the lower surface in FIGS. 5B and 5C) side of the base tape 25. The sampling seals S, S,... Are detachably adhered. Note that the drawings are drawn schematically and greatly enlarged in the thickness direction, with the aim of facilitating understanding, but the thickness of the sampling tape T is actually a thin film-like one And the boundaries of each layer are not as clear as shown.

The base tape 25 functions as a support base until the sampling seal S is peeled off by the peeling head H, and is made of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene, polypropylene, or the like. It is in the form of a film-like tape made of a plastic material or a paper material, and a flexible film that does not stretch is suitably employed. A thickness t ₂₅ of the base tape 25 is set to about 6 to 38 μm.

The base tape 25 of the illustrated embodiment is made of a polyethylene terephthalate film, and has a thickness dimension t ₂₅ of 12 μm and a width dimension W ₂₅ of 10 mm.

  In addition, the surface of the base tape 25 is subjected to a surface treatment in which a light adhesion treatment layer 26 is formed, and the back surface of the base tape 25 is subjected to a surface treatment in which a release treatment layer 27 is formed. ing.

The light adhesion treatment layer 26 ensures the function as the support base material, and more specifically, the sampling seal S is stably adhered to the base tape 25 when the sampling tape T is stored. In addition to fixing, the collection seal S can be easily separated from the base tape 25 when the collection seal is peeled off. As a constituent material of the light pressure-sensitive treatment layer 26, a light pressure-sensitive adhesive composition such as an acrylic pressure-sensitive adhesive is preferably used. For example, the light pressure-sensitive adhesive plastic material is applied to the base tape 25 and then dried. The light adhesion treatment layer 26 is formed by surface treatment by sandblasting. The light-tack treatment layer 26 of the illustrated embodiment has a thickness dimension t ₂₅ set to 13 μm.

  The release treatment layer 27 provides separation or peelability from adjacent layers or materials that overlap, and more specifically, when the collection tape T is wound around a roll and stored, it adheres to the collection seal S. This is to prevent the sampling seal S from being easily peeled off from the base tape 25 and transferred. As a constituent material of the release treatment layer 27, a release agent such as a silicone release agent or a fluorine release agent is preferably used. For example, the release agent is applied to the base tape 25 and dried. Thus, the release treatment layer 27 is formed.

  The collection seal S is in the form of a rectangular strip-shaped adhesive seal. Specifically, the collection seal S is a rectangle having a shape and dimension corresponding to the application area of the collection application paste P for attaching the collected identification object O. It is formed in a strip shape.

In the illustrated embodiment, the sampling seal S is configured such that the thickness dimension t _S is 53.5 μm, the length dimension L _S is 20 mm, and the width dimension W _S is 4 mm.

  As shown in FIG. 5, the collection seal S has a structure in which a pressure-sensitive adhesive layer 29 is integrally formed on a part of the main body sheet 28, and the pressure-sensitive adhesive layer 29 will be described later. A sampling surface Sa of the sampling seal S is formed.

  The main body sheet 28 is formed by integrally laminating a surface layer 30 that forms the surface of the sampling seal S and a mark layer 31 on which marks for marks are formed.

  In the illustrated embodiment, the surface layer 30 provides the sampling seal S with a characteristic as a seal body and forms the surface layer of the sampling seal S after transfer.

  The constituent material of the surface layer 30 is an electrode made of one or more synthetic resins or natural resin materials, or these resin materials or paper materials, which can maintain toughness as a sealing body and have transparency that can be seen through. A thin film is preferably used, more preferably a polyethylene terephthalate (PET) film or a resin mixture film of a rubber-like resin and a glass-like resin. Thus, the characteristic as a sealing body can be provided to the surface layer 30 by using rubber-like resin and glass-like resin together.

  Examples of the rubber-like resin include styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butylene-styrene block copolymer (SEBS), styrene-butadiene rubber, styrene-isoprene-styrene block copolymer ( SIS), styrene-ethylene / propylene block copolymer (SEP), urethane rubber, fluoro rubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, chlorosulfonated polyethylene, cyclization One type or two or more types of normal synthetic rubber such as rubber or rubber-like resin can be used. In addition, you may use a plasticizer together as needed.

  As the glassy resin, those having a melting point or softening point of 100 ° C. or higher and high hardness are preferable, for example, saturated or unsaturated alicyclic hydrocarbon resins, styrene-acrylic copolymer resins, ketones. Resins, vinyl chloride-vinyl acetate copolymer resins, polyolefin resins such as polyethylene and polypropylene, and the like can be used.

  Further, the surface layer 30 may be blended with a light diffusing agent or a colorant (pigment or dye) to make the surface layer 30 translucent or colored. However, the entire surface layer 30 is colorless and transparent. This is also preferable from the viewpoint of ensuring the visibility when the object O is stuck and collected and the visibility of the mark layer 31.

  The layer thickness of the surface layer 30 is set to 25 to 50 μm. The layer thickness of the surface layer 30 is set in such a range as long as there is no appropriate thickness (less than 25 μm), the sampling seal S has no stiffness and the sampling tape T is peeled off as described later. The elastic recovery action of the sampling seal S itself to the flat plate state when guided back by the front edge Ha of the H becomes insufficient, the peeling from the base tape 25 is not performed reliably, and the characteristics as a seal body This is because the workability is poor because it is too soft when sticking and collecting the identification object O. On the other hand, if the thickness of the surface layer 30 is larger than 50 μm (if the thickness is too large), the collection seal S is too stiff and the thickness of the collection tape T itself increases, and the reel 5 of the collection tape T is fed out. Winding around becomes difficult. The layer thickness of the surface layer 30 in the illustrated embodiment is set to 38 μm.

  The mark layer 31 is a layer that forms a mark mark of the sampling seal S. Specifically, a part of the sampling seal S is colored, and a mark mark that visually displays a predetermined part of the sampling seal S is formed. The In the illustrated embodiment, two mark marks Ma and Mb are formed.

  One mark mark Ma is formed at the tip portion of the collection seal S to visually display the tip portion of the collection seal S, and the other mark mark Mb is formed at a non-adhesive surface portion of the collection seal S to be described later. Thus, the non-adhesive surface portion is visually displayed.

  Specifically, the mark layer 31 is formed on the surface layer 30 by a conventionally known printing technique. As the printing method of this mark layer 31, various conventionally known printing techniques, specifically, traditional printing techniques such as letterpress (letter printing) printing, offset printing, gravure printing (intaglio printing), silk screen printing, tampo printing, etc. In addition, various coaters such as reverse roll coating and direct coating, spray coating, electrostatic coating, flow coating, roller coating, dip coating, and other new printing technologies such as laser printer method, thermal transfer method, and ink jet printer method are also adopted. It is possible to select and adopt as appropriate according to the properties of the portion to be formed (the surface layer 30 in the case of illustration). As the mark layer forming ink, an ink in which a resin and a colorant are dissolved or dispersed in a solvent as required is used.

  Preferred examples of the resin include the rubber-like resins described above, that is, styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butylene-styrene block copolymer (SEBS), and styrene-butadiene. Rubber, styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene / propylene block copolymer (SEP), urethane rubber, fluororubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate copolymer, ethylene-ethyl One type or two or more types of usual synthetic rubber or rubber-like resin such as acrylate copolymer, chlorosulfonated polyethylene, and cyclized rubber can be used. You may use a plasticizer together as needed.

  Moreover, as said colorant, the well-known colorant currently used for general printing ink can be used suitably.

  The mark layer 31 is formed by printing such a printing layer forming ink on the surface layer 30 and then drying. As shown in the figure, the mark layer 31 may be printed on the back surface side (the lower surface side in FIGS. 5B and 5C) or on the front surface side. Moreover, the layer thickness of the mark layer 31 is usually 0.1 to 5 μm, and in the illustrated embodiment, it is 0.5 μm.

  The pressure-sensitive adhesive layer 29 has a function of sticking and collecting the identification object O, which is its original function, on the collection seal S and affixing and fixing the collected identification object O on the collection pasteboard P. The pressure sensitive adhesive layer 29 is formed on a part of the main body sheet 28, specifically, a predetermined length direction portion from the front edge thereof, and the sampling seal S is sampled. A surface Sa is formed.

In the illustrated embodiment, as shown in FIGS. 5 (a) and 5 (b), in the length direction of the main body sheet 28, the pressure sensitivity is within a length range L ₁ (= 14 mm) of 2/3 from the front end thereof. A pressure-sensitive adhesive layer 29 is laminated. As a result, in the sampling seal S, the pressure-sensitive adhesive layer 29 portion forms the sampling surface Sa of the sampling seal S, and the rear side of the sampling surface Sa (sampled from the rear end of the pressure-sensitive adhesive layer 29). The non-adhesive surface Sb without the pressure-sensitive adhesive layer 29 is formed up to the rear end of the seal S).

In relation to this, the mark mark Ma formed on the distal end portion of the sampling seal S is formed in a range of L ₂ = 1 mm from the distal end of the sampling seal S, and also on a non-adhesive surface portion described later on the sampling seal S. The mark Mb is formed in a range of L ₃ = 6 mm (non-adhesive surface Sb portion) from the rear end of the sampling seal S.

  As the pressure-sensitive adhesive layer 29, the pressure-sensitive adhesive layer 29 is preferably a conventionally known pressure-sensitive adhesive such as a rubber-based pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive. For example, natural rubber, isoprene rubber, styrene-butadiene rubber, etc. In addition, a rubber-based pressure-sensitive adhesive containing a tackifier (rosin-based resin, terpene-based resin, terpene-phenol-based resin, or the like) or an acrylic pressure-sensitive adhesive mainly composed of a (meth) acrylic ester is used.

  Then, the pressure-sensitive adhesive layer 29 is integrally laminated on the main body sheet 28 by coating the pressure-sensitive adhesive on the surface layer 30 provided with the mark layer 31 by a conventionally known method. The sampling surface Sa of the sampling seal S is formed. The thickness of the pressure-sensitive adhesive layer 29 is usually set to 10 to 20 μm, and is set to 15 μm in the illustrated embodiment.

  Moreover, the adhesive force of the pressure-sensitive adhesive layer 29 is set to be larger than the sticking holding force of the sampling seal S to the base tape 25. The specific adhesive force of the pressure-sensitive adhesive layer 29 is appropriately set in accordance with the type of the identification object O to be collected within a range satisfying the above conditions. For example, when the identification object O is hair, the pressure-sensitive adhesive layer 29 has an adhesive strength of 650 g / 25 mm and an inclined ball tack of 8 ball tack (all according to JIS Z 0237). ing.

  As shown in FIGS. 5 (a) to 5 (c), the sampling seal S having such a laminated structure has a peel-treated surface of the base tape 25 (FIG. 5 (b) and FIG. 5 (c). ), The lower surface on which the release treatment layer 27 is formed is adhesively held so as to be peeled through the surface layer 30 of the main body sheet 28 with a predetermined interval I. In other words, the sampling seal S is adhesively held on the base tape 25 so as to be peelable with the sampling surface Sa facing outside. In the illustrated embodiment, the predetermined interval I is set to 7 mm.

  The collection tape T configured as described above is wound around the supply reel 5 with the surface on which the collection seals S, S,... Are adhered and held outward, and is supplied from the supply reel 5. The collected tape T is guided to the peeling head H through the guide pins 13 and 14 as it is, and is turned back by the tip pressurizing portion Ha of the peeling head H, and is then passed through the guide pin 15. It is wound around the take-up reel 6.

  Then, when the sampling tape T is guided back through the tip edge Ha of the peeling head H, the sampling seal S that is stuck and held on the base tape 25 of the sampling tape T is brought into its own flat state. 4 is peeled off from the base tape 25 by the elastic return action, but in the temporary peeling state before the sampling seal S is completely peeled from the base tape 25, the sampling seal S is peeled off as shown in FIG. In this temporarily peeled state, the adhesive surface of the sampling seal S, that is, the sampling surface Sa faces downward as shown in the figure, and is in a posture suitable for sticking and collecting the object to be identified O. .

  Further, since the sampling seal S is wound around the feeding reel 5 together with the base tape 25, even if it is peeled off from the base tape 25, some curl remains as shown in the figure and it is completely flat. Although the state does not return, the state of being curved in an arc shape is preferable because it is in a posture suitable for sticking and collecting the object of discrimination O.

  The operation dial 12 constitutes a tape feeding means for manually feeding the sampling tape T from the outside of the device case 2 as a component of the sampling device 1, and includes a device main body (device case 2) and Is a separate product, and is configured to be used in combination with the main body of the apparatus when the object to be identified O is collected.
