Description

[Technical Field]

[0001] The present invention relates to a width ruler that guides a cutter that cuts the edge of an adhesive sheet, leaving a predetermined width from the ridge of a surface member. [Background technology]

[0002] BACKGROUND ART Conventionally, a cutter guide that guides a cutter that cuts a sheet member to be attached to a building material has been known (Patent Document 1). This cutter guide has a first guide member for guiding the cutter, a second guide member that is slidable relative to the first guide member, and a fixing device that secures the first guide member and the second guide member to each other, wherein the first guide member has a cutter guide surface for guiding the cutter, and the second guide member has a slide guide surface for contacting the building material or the sheet member, and the angle formed by the cutter guide surface and the slide guide surface is within the range of -1° or more and 1° or less before and after the second guide member slides relative to the first guide member.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-189280 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in the cutter guide described in Patent Document 1, as disclosed in FIGS. 2, 8 to 13 and the like, the distance between the cutter guide surface and the slide guide surface can be freely adjusted by the scale portion. However, although the distances frequently used at actual work sites are limited to 5 mm, 10 mm, 15 mm, etc., when using the cutter guide described in Patent Document 1, regardless of the distance, the guide members cannot be fixed together without checking the scale each time, which means that checking the scale requires extra work time and effort, reducing work efficiency.

[0005] Furthermore, as also shown in Figures 2, 8 to 13, etc., the cutter guide described in Patent Document 1 has only one slide groove that allows the first guide member to slide relative to the second guide member, and unless there is a slight gap between the first guide member and the second guide member, the first guide member cannot slide, so the first guide member will sway (rattle) slightly around the fixing device that fixes the first guide member at a predetermined position in the slide groove. Generally, in construction materials, sheet members are often attached to surface members such as wall surfaces, ceiling surfaces, floor surfaces, and door surfaces, and naturally, large sheet members need to be attached to these surface members. However, when using the cutter guide described in Patent Document 1 to cut a large sheet material with a cutter roughly along the horizontal direction, for example, if the user is right-handed, the cutter will press against the left side of the first guide member to make the cut immediately after cutting begins, causing the first guide member to swing to the left.However, just before cutting ends, the cutter will press against the right side of the first guide member to make the cut, causing the first guide member to swing to the right (causing the first guide member to wobble), and the distance between the cutter guide surface and the slide guide surface will strictly change between just after cutting begins and just before cutting ends, resulting in the problem that the sheet material cannot be cut straight.

[0006] Therefore, the purpose of this invention is to provide a width ruler that can achieve ``improved workability'' and ``reduced rattling'' by having two or more slide groove portions with recesses that position abutment bodies, etc. at predetermined intervals. [Means for solving the problem]

[0007] The width ruler 1 according to the present invention is a width ruler that guides a cutter C when an adhesive sheet S is attached from a surface M1 of a surface member M across a ridge line MR to a side edge surface M2, and the edge of the adhesive sheet S attached to the side edge surface M2 is cut with the cutter C, leaving a predetermined width W from the ridge line MR. The width ruler comprises a guide body 2 having a guide surface 2a that can guide the cutter C, an abutment body 3 having an abutment surface 3a that is movable relative to the guide surface 2a and can abut on the surface M1 side, and an adjustment mechanism that adjusts the surface distance W' between the abutment surface 3a and the guide surface 2a. 4, and a surface distance W' adjusted by the adjustment mechanism 4 becomes approximately equal to the predetermined width W when the abutment surface 3a abuts on the surface M1 side, and the adjustment mechanism 4 includes a slide groove portion 5 provided in the guide main body 2 and sliding the abutment body 3 approximately along the normal direction of the guide surface 2a, positioning recesses 6 provided at predetermined intervals in the slide groove portion 5 and positioning the abutment body 3, and a fixing device 7 provided in the slide groove portion 5 and capable of fixing the abutment body 3 at any position, and the number of the slide groove portions 5 is two or more.

[0008] A second feature of the width ruler 1 according to the present invention is that, in addition to the first feature, the number of the fixing devices 7 is two or more.

[0009] The third feature of the width ruler 1 of the present invention is that, in addition to the first feature, the adjustment mechanism 4 is equipped with a slide restraint section 8 that restrains the sliding of the abutment body 3 approximately along the normal direction of the guide surface 2a.

[0010] The fourth feature of the width ruler 1 of the present invention is that, in addition to the first feature, the planar shape of the guide body 2 is approximately rectangular, and the corners of the approximately rectangular guide body 2 are cut out at an angle.

[0011] The fifth feature of the width ruler 1 of the present invention is that, in addition to the first feature described above, it has a holder member 10 that can hold the width ruler, and the holder member 10 has a holder main body portion 11 that detachably holds the guide body 2 of the width ruler, and a hook portion 12 attached to the rear side of the holder main body portion 11.

[0012] The sixth feature of the width ruler 1 of the present invention is that, in addition to the fifth feature, it is provided with a main body magnet 11A that can magnetize the holder main body portion 11 and the width ruler side, and / or the hook portion 12 is approximately U-shaped when viewed from the side, and is provided with a hook magnet 12A that can magnetize the tip ends of the two arms of the hook portion 12 that is approximately U-shaped when viewed from the side.

[0013] The seventh feature of the width ruler 1 of the present invention is that, in addition to the fifth feature, the holder member 10 is equipped with a connector 13 that detachably connects the hook portion 12 to the holder main body portion 11.

[0014] The eighth feature of the width ruler 1 according to the present invention is that when an adhesive sheet S is attached from the surface M1 of a surface member M across the ridge line MR to a side edge surface M2, the width ruler guides the cutter C when the edge of the adhesive sheet S attached to the side edge surface M2 is cut with the cutter C, leaving a predetermined width W from the ridge line MR. The width ruler includes a contact body 22 having a contact surface 22a that contacts the surface M1, a guide body 23 having a guide surface 23a that is movable relative to the contact surface 22a and guides the cutter C, and an adjustment mechanism for adjusting the surface distance W' between the guide surface 23a and the contact surface 22a. 24, and a surface distance W' adjusted by the adjustment mechanism 24 becomes approximately equal to the predetermined width W when the abutment surface 22a abuts on the surface M1 side, and the adjustment mechanism 24 includes slide groove portions 25 provided on the abutment main body 22 and sliding the guide body 23 approximately along the normal direction of the abutment surface 22a, positioning recesses 26 provided at predetermined intervals in the slide groove portion 25 and positioning the guide body 23, and fixing devices 27 provided in the slide groove portion 25 and capable of fixing the guide body 23 at any position, and the number of the slide groove portions 25 is two or more.

[0015] The ninth feature of the width ruler 1 of the present invention is that, in addition to the eighth feature, the abutment body 22 is a substantially rectangular plate-shaped material, and the abutment surface 22a is provided on one side end face 22A of the abutment body 22, which is a substantially rectangular plate-shaped material, and the squeegee portion 28 is provided on the side end face 22C opposite to the one side end face 22A.

[0016] A tenth feature of the width ruler 1 of the present invention is that, in addition to the eighth feature, the abutment body 22 is a substantially rectangular plate-shaped material, and the abutment surface 22a is provided on each of two adjacent side end faces 22A, 22B of the abutment body 22, which is a substantially rectangular plate-shaped material, and each of the slide groove portions 25 is formed in a shape that allows the guide body 23 to slide approximately along the normal direction of each of the two side end faces 22A, 22B.

[0017] Due to these features, the width ruler 1 that guides the cutter C that cuts the edge of the adhesive sheet S from the ridge line MR of the surface member M, leaving a predetermined width W, moves relative to the guide main body 2 with the guide surface 2a of the cutter C and has an abutment body 3 with an abutment surface 3a that contacts the surface member M, and the slide groove portion 5 is provided with positioning recesses 6 that position the abutment body 3 at predetermined intervals. Therefore, unlike Patent Document 1, if the positioning recesses 6 are provided every 5 mm, etc., even if the predetermined width W is 5 mm, 10 mm, 15 mm, etc., which are frequently used at work sites, the cutter C can be immediately guided by the guide main body 2 at the desired surface distance W' (predetermined width W) by simply fitting the abutment body 3 into the positioning recess 6 without checking the scale, and the work time and effort can be reduced and workability improved by the amount that the scale is not checked ("improved workability"). In addition, by providing two or more slide groove portions 5, the rocking (rattle) of the abutment body 3 relative to the guide body 2 is minimized ("rattle suppression") compared to when there is only one slide groove, as in Patent Document 1. Therefore, even when attempting to cut a large sheet material approximately horizontally with a cutter, the surface distance W' (i.e., the predetermined width W) between the contact surface 3a and the guide surface 2a can be kept approximately constant from immediately after cutting begins to immediately before cutting ends, making it easier to cut the adhesive sheet S straight. The width ruler 1 can be said to be a "cutter guide."

[0018] In addition, by providing two or more fixing devices 7 that fix the abutment body 3 at any position, or by providing a slide restraint section 8 for the abutment body 3, the oscillation (rattle) of the abutment body 3 relative to the guide body 2 can be further suppressed (further ``rattle suppression'' can be achieved). Furthermore, by cutting out the corners of the approximately rectangular guide body 2 at an angle, it is possible to cut the adhesive sheet S at an angle by running a cutter C along the corners, or if the corners are cut at a 45° angle, it can be used for finishing work on wood, etc. (a process in which surfaces cut at a 45° angle (end and fore edges) are butted together to create a 90° frame).

[0019] Furthermore, the holder member 10 is provided with not only the holder main body portion 11 that detachably holds the guide main body 2 of the width ruler 1, but also the hook portion 12, so that the width ruler 1 held by the holder member 10 can be attached to a waist tool, belt, etc. of the user via the hook portion 12. Furthermore, by providing a main body magnet 11A that can magnetize the holder main body 11 and the width ruler 1 side (at least a part of it), and by providing a hook magnet 12A that can magnetize the tip ends of each arm of the hook portion 12 that is approximately U-shaped when viewed from the side, it becomes difficult for the width ruler 1 to come off from the holder main body 11, and the hook portion 12 to come off from the user's waist tool, belt, etc., thereby preventing the width ruler 1 and holder member 10 from falling or being lost. Furthermore, by providing a connector 13 that can detachably connect the hook portion 12 and the holder main body portion 11, it is possible to provide a case member that can be detachably attached to the connector 13 between the hook portion 12 and the holder main body portion 11, and store specified items (other tools, writing utensils, memo paper, portable devices, etc.) inside the case member, thereby expanding the variety of uses.

[0020] In addition, the width ruler 1 may be not only the first embodiment having the guide body 2, the contact body 3, and the adjustment mechanism 4 described above, but also the second embodiment having the contact body 22, the guide body 23, and the adjustment mechanism 24. The width ruler 1 of this second embodiment has a guide body 23 with a guide surface 23a for the cutter C that moves relative to the contact body 22 with a contact surface 22a for the surface member M, and positioning recesses 26 that position the guide body 23 at predetermined intervals are provided in the slide groove portion 25, thereby achieving "improved workability" and "reduced rattling" as in the first embodiment, and making it easier to cut the adhesive sheet S straight even when trying to cut a large sheet member approximately along the horizontal direction with the cutter. In addition, by providing a squeegee portion 28 on the side opposite to the contact surface 22a of the contact body 22, which is a substantially rectangular plate-like material, the width ruler 1 can also be used as a squeegee. In addition, the contact surfaces 22a are provided on two adjacent side end surfaces 22A and 22B (which are perpendicular to each other across a ridge line) of the contact body 22, which is a substantially rectangular plate-like material, and the slide grooves 25 are formed in a shape that allows the guide body 23 to slide substantially along the normal direction of each of the contact surfaces 22a. This makes it possible to "slide obliquely" the guide body 23 in the longitudinal direction and the lateral direction (two directions that are perpendicular to each other) of the substantially rectangular contact body 22, and for example, it is possible to slide the guide body 23 obliquely in the inside corner of a wall surface (wall surface, etc. Even when cutting the end of the adhesive sheet S with a cutter C, leaving a predetermined width W in two directions, at the side end faces (end grain and fore edge) of the surface parts M of the board (the recessed corner formed when the surface parts M are joined inward), by using this width ruler 1 which can be "slid diagonally", it is possible to complete the work with a single contact by sliding the ruler a predetermined surface distance W' in both the longitudinal and lateral directions and bringing the two contact surfaces 22a into contact with the two surfaces M1 that are joined inward. [Effects of the Invention]

[0021] According to the width ruler of the present invention, by providing two or more slide groove portions with recesses that position abutment bodies, etc. at predetermined intervals, it is possible to achieve ``improved workability'' and ``reduced rattling.''

DETAILED DESCRIPTION OF THE INVENTION

[0023] <Width ruler 1 according to the first embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 5 illustrate a width ruler 1 according to a first embodiment of the present invention. The width ruler 1 of the first embodiment is a ruler that guides the cutter C when the adhesive sheet S is attached from the surface M1 of the surface member M across the ridge line MR to the side end surface M2, and when the edge of the adhesive sheet S to be attached to the side end surface M2 of the surface member M is cut with the cutter C, leaving a predetermined width W from the ridge line MR of the surface member M. It can also be said to be a tool or jig. The width ruler 1 according to the first embodiment has a guide body 2, a contact body 3, and an adjustment mechanism 4, which will be described later. Moreover, the width ruler 1 according to the first embodiment may have a holder member 10, which will be described later, and may also have a connecting plate 9, which will be described later.

[0024] The materials for the guide body 2 and the abutment body 3 in the width ruler 1 according to the first embodiment are not particularly limited, and may be, for example, acrylonitrile butadiene styrene (ABS) resin, polylactic acid (PLA) resin, polyester resins such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyolefin resins such as polypropylene (PP) and polyethylene (PE), polyethylene terephthalate glycol (PETG), polyethylene terephthalate glycol (TPU) resin, thermoplastic elastomer (TPE), polystyrene (PS) resin, so-called engineering plastics such as epoxy resin, acrylic resin, polyurethane (PU) resin, silicone resin, polyacetal (POM) resin, polycarbonate (PC) resin, nylon (polyamide) resin, modified polyphenylene ether (m-PPE) resin, or other materials such as metal, wood, stone, or the like, which may be used alone or in combination. On the other hand, the material of the parts of the width ruler 1 in the first embodiment other than the guide body 2 and the abutment body 3 may be metal, wood, stone, etc., or may be the same material as the guide body 2 and the abutment body 3 described above, such as resin. Below, the surface member M, adhesive sheet S, cutter C, and predetermined width W, which are the objects to be worked on with the width ruler 1, will first be described.

[0025] <Face member M, its surface M1, side end surface M2, ridge line MR> As shown in FIG. 1, the surface member M is a member such as a panel material or a roughly plate-shaped material, and is used, for example, for wall surfaces, ceiling surfaces, floor surfaces, door surfaces, other interior surfaces, and also for constructing tables (tops) and furniture. The surface member M has a predetermined width and a predetermined thickness, such as a wall surface, and its widest and most visible surface is referred to as the surface M1. Note that the surface M1 is also called the main surface. Furthermore, in the surface member M, the four faces that surround the surface M1 and indicate the thickness are called side end faces M2. If the shape of the surface member M in a plan view is, for example, approximately rectangular, the faces along the longitudinal direction (length direction) (long or wide side end faces) are also called small edges, and the faces along the lateral direction (width direction) (short or narrow side end faces) are also called edges. These small edges and small edges are all referred to as side end faces M2.

[0026] The width of the side end surface M2 (i.e., the thickness of the surface member M) is not particularly limited, but may be, for example, 5 mm or more and 100 mm or less, and more specifically, the lower limit may be 5 mm or more, preferably 10 mm or more, and more preferably 15 mm or more, and the upper limit may be 100 mm or less, preferably 80 mm or less, and more preferably 60 mm or less (e.g., 40 mm). Each lower limit value of the thickness of the surface member M may be combined with any of the upper limits. In such a surface member M, the line (corner line) between the surface M1 and the side end surface M2 is the ridge line MR, and the adhesive sheet S described below is attached from the surface M1 of the surface member M across the ridge line MR to the side end surface M2.

[0027] <Adhesive Sheet S> 1, the adhesive sheet S is a sheet-like object in which an adhesive is applied to one side (rear side) of a sheet substrate, making the rear side an adhesive surface, and the adhesive surface may be covered with release paper. The adhesive sheet S is also called a DI-NOC (registered trademark) sheet, a DI-NOC (registered trademark) film, a decorative sheet, a cutting sheet, etc. The specific configuration of the adhesive sheet S is not particularly limited, but for example, the sheet substrate may be an acrylic resin, a polyester resin such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), a polyolefin resin such as polypropylene (PP) or polyethylene (PE), polyvinyl chloride (PVC) resin, polyvinylidene chloride (PVDC) resin, polyvinyl alcohol (PVA) resin, polystyrene (PS) resin, polycarbonate (PC) resin, polyurethane (PU) resin, or the like, made into a sheet or film using any of these alone or in combination, or other paper such as high-quality paper, glassine paper, or coated paper.

[0028] The adhesive material is not particularly limited, and may be, for example, an acrylic resin, a polyester resin such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), a polyolefin resin such as polypropylene (PP) or polyethylene (PE), or a rubber-based adhesive or a silicone-based adhesive, which may be used alone or in combination. The surface (design surface) of such an adhesive sheet S is not particularly limited, but may have, for example, a wood grain pattern, a marble or other stone pattern, or a geometric figure, letter, symbol, abstract pattern, landscape, character, or other image.

[0029] <Cutter C> As shown in FIG. 1, the cutter C is a tool that cuts the above-described adhesive sheet S while being guided by the width ruler 1 according to the first embodiment (substantially along the width ruler 1). The specific configuration of the cutter C is not particularly limited, but it may be, for example, a cutter knife, or other cutting tools such as a rotary cutter or a design knife, and its size may range from large to medium to small. Hereinafter, the cutter C will be mainly described as a cutter knife.

[0030] <Predetermined width W> 1, the predetermined width W is the width of the adhesive sheet S at the end portion from the ridge line MR of the surface member M when the end portion of the adhesive sheet S to be attached to the side end surface M2 of the surface member M is cut with the cutter C, leaving a portion from the ridge line MR of the surface member M. It can also be called the predetermined cutting width W. If such an adhesive sheet S of a predetermined width W is left on the side edge M2 of the surface member M, and the adhesive sheet S is cut at the edge (i.e., the ridge line MR) of the surface M1 of the surface member M, there is a risk that the adhesive sheet S will peel off from the edge from the surface M1 of the surface member M after installation, so it can be said that it is necessary to leave the end of the adhesive sheet S on the side edge M2 of the surface member M by the predetermined width W. The value of this predetermined width W is not particularly limited, but may be, for example, 5 mm or more and 100 mm or less, and more specifically, the lower limit may be 5 mm or more, preferably 10 mm or more, and more preferably 15 mm or more, and the upper limit may be 100 mm or less, preferably 80 mm or less, and more preferably 60 mm or less (it may be a delimiting value such as 5 mm, 10 mm, 15 mm, or 20 mm, but may also be 6 mm, 7 mm, 13 mm, etc.). Note that each lower limit value of this predetermined width W may be combined with any of the upper limits.

[0031] <Guide body 2> As shown in FIGS. 1 to 5, the guide body 2 is a member that serves as the base of the width ruler 1 according to the first embodiment, and is a portion that has a guide surface 2a that can guide the cutter C described above. It can be said that the guide body 2 is provided with an adjustment mechanism 4 (slide groove portion 5 and the like) which will be described later. The overall shape of the guide body 2 is not particularly limited, but it may be a plate-like body, and its planar shape may be, for example, approximately rectangular, approximately square, or other approximately polygonal shapes such as approximately hexagonal or approximately triangular, or may be approximately circular or approximately elliptical as long as it has a guide surface 2a described below. In addition, the guide body 2 may be approximately rectangular, cubic, or polygonal such as a hexagonal or triangular prism, or may be approximately spherical or ellipsoidal, as long as it has a guide surface 2a described below. Hereinafter, the guide body 2 will be mainly described as being a substantially rectangular plate-like body.

[0032] The guide body 2, which is a roughly rectangular plate-like body, may have at least one corner portion cut out at an angle, and the angle of the cutout is not particularly limited, but may be, for example, 45°, or other angles such as 30° or 60°. Furthermore, if two or more of the four corners of the guide body 2, which is an approximately rectangular plate-shaped body, are cut out, the cut-out angles of each corner may all be approximately the same, but it is also acceptable for some of the two or more corners to have different angles.

[0033] <Guide surface 2a> As shown in Figures 1 to 5, the guide surface 2a is a surface provided on the above-mentioned guide body 2, and the above-mentioned cutter C (particularly, the cutting edge) abuts against this guide surface 2a, and the cutter C moves approximately along the guide surface 2a while cutting with this cutting edge (this cutting while moving approximately along the guide surface 2a is called guiding). The guide surface 2a guides the cutter C, which cuts the edge of the adhesive sheet S leaving a predetermined width W, so that the cutter C cuts mainly in a straight line, and in this case, the guide surface 2a can be said to be approximately flat (approximately planar). Furthermore, as long as the edge of the adhesive sheet S can be cut with a certain width, it is not necessary to cut it in a straight line with the cutter C (for example, it can be cut in a curved line, such as a wavy or slightly inclined shape), and in this case the guide surface 2a can be a curved surface (for example, a wavy surface or a slightly inclined surface).

[0034] Such a guide surface 2a may be provided at any position on the guide body 2, but for example, any of the side end faces (particularly any of the side end faces on the two long sides) of the four sides (side end faces) of the guide body 2, which is an approximately rectangular plate-like body, may be the guide surface 2a, or two or more guide surfaces 2a may be provided on one guide body 2, such as any of the side end faces on the two short sides, both of the side end faces on the two long sides, or the side end faces on the long and short sides. The guide surface 2a may be subjected to a surface smoothing treatment such as polishing or lapping, a hardening treatment such as hard chrome plating or nitriding, or a fluororesin coating.

[0035] <Abutting body> As shown in FIGS. 1 to 5, the contact body 3 is a part that is movable relative to the above-mentioned guide surface 2a (guide main body 2) and has a contact surface 3a that can contact the surface M1 side of the plane member M. The overall shape of the abutment body 3 is not particularly limited, but it may be a rod-like body, and its cross-sectional shape may be, for example, approximately square (i.e., approximately rectangular), approximately rectangular, or other approximately polygonal shape such as approximately hexagonal or approximately triangular, or may be approximately circular or approximately elliptical as long as it has the abutment surface 3a described below. In addition, the abutment body 3 may have a shape other than a rod-like body (more block-like), for example, an approximately rectangular parallelepiped shape or an approximately cubic shape, or may have an approximately spherical shape or an approximately ellipsoid shape as long as it has the abutment surface 3a described below. Hereinafter, the contact body 3 will be mainly described as being substantially in the shape of a square bar.

[0036] The specific configuration of the abutment body 3, which is approximately square rod-shaped, is not particularly limited, but it may, for example, have an abutment base portion 3A which is a rod-shaped body that is approximately rectangular in cross section, and an abutment slide portion 3B which is also a rod-shaped body that is approximately rectangular in cross section. The contact base portion 3A may include a base fixing insertion hole (not shown) through which a fixing shaft portion 7b of a fixing tool 7 described later is inserted, a slide insertion hole 3A1 through which a restraining shaft portion 8a of a slide restraining portion 8 described later is inserted, and a protruding portion 3A2 surrounding the slide insertion hole 3A1. In addition, a bearing member (not shown) that receives the restraining shaft portion 8a may be built into the protruding portion 3A2, and the bearing member may be made of a material that can be magnetized by a main body magnet 11A in a holder main body portion 11 of a holder member 10 described later (for example, a metal that is attracted to a magnet, such as iron, nickel, or cobalt, or the magnet itself). Furthermore, the length of the abutment base portion 3A may be approximately the same as the length of the guide main body 2 in the longitudinal direction, and the base fixing insertion hole may be approximately elongated. As a result, regardless of which of the positioning recesses 6 provided on both sides of the slide groove portion 5 (described later) the fixed shaft portion 7b moves within the approximately elongated base fixing insertion hole, so that the longitudinal position of the abutment base portion 3A relative to the guide main body 2 does not change (the side end faces (small edges) at both ends of the length of the abutment base portion 3A can be kept approximately flush with the side end faces at both ends of the length of the guide main body 2).

[0037] The contact slide portion 3B may have a slide fixing insertion hole 3B1 through which a fixing shaft portion 7b of a fixture 7 described later is inserted, and a fixing recess 3B2 into which a fixing fastener portion 7c of the fixture 7 is fitted. Here, the length of the abutment slide portion 3B may be shorter than the length of the abutment base portion 3A (for example, shorter by approximately the same length as the length of the above-mentioned substantially elongated base fixing insertion hole). As a result, regardless of which of the positioning recesses 6 provided on both sides of the slide groove portion 5 described below the fixed shaft portion 7b fits into, the fixed shaft portion 7b moves within the substantially elongated base fixing insertion hole, and the abutment slide portion 3B also moves together with the movement of the fixed shaft portion 7b, so that the abutment slide portion 3B can slide relative to the abutment base portion 3A. Both ends of the contact slide portion 3B in the length direction may be cut out obliquely in a direction in which the length of the contact slide portion 3B increases as it approaches the contact base portion 3A.

[0038] <Abutment surface 3a> As shown in FIGS. 1 to 5, the contact surface 3a is a surface provided on the contact body 3 described above, and this contact surface 3a comes into contact with the surface M1 side of the planar member M described above. Here, "contacting the surface M1 side of the surface member M" means that since the surface M1 of the surface member M is covered with the adhesive sheet S, the contact surface 3a cannot directly contact the surface M1, but it can be said that it is in contact with the surface M1 via the adhesive sheet S (over the adhesive sheet S), and that this state is possible. Since the surface M1 of the plane member M is usually substantially flat (substantially planar), the contact surface 3a can be said to be substantially flat (substantially planar) even when the contact is made through the adhesive sheet S. Furthermore, if the surface M1 of the surface member M has unevenness, protrusions, or a wavy shape, a curved surface corresponding to the unevenness, protrusions, wavy shape, etc. may also be formed on the abutment surface 3a.

[0039] Such a contact surface 3a may be provided at any position on the contact body 3, but for example, in a substantially square bar-shaped contact body 3, the surface on the same side as the guide surface 2a of the above-mentioned guide main body 2 (strictly speaking, the side end surfaces on the same sides as the guide surface 2a of the above-mentioned contact base portion 3A and contact slide portion 3B) may be the contact surface 3a. Also, the contact surface 3a may be substantially parallel to the guide surface 2a in three-dimensional space. Furthermore, since the abutment surface 3a may slide along the surface M1 of the surface member M (strictly speaking, the surface of the adhesive sheet S), the material on the abutment surface 3a side may be a relatively soft polyolefin resin such as polypropylene (PP) or polyethylene (PE), but the same material may also be used for the abutment body 3 (the abutment base portion 3A and the abutment slide portion 3B) including the abutment surface 3a side.

[0040] <Adjustment mechanism 4> As shown in FIGS. 1 to 5, the adjustment mechanism 4 is a mechanism for adjusting the surface distance W' between the guide surface 2a of the guide main body 2 and the contact surface 3a of the contact body 3. The adjustment mechanism 4 includes a slide groove portion 5, a positioning recess 6, and a fixture 7, which will be described later. The adjustment mechanism 4 may include a slide restraint portion 8, which will be described later. First, the relationship between the surface distance W' adjusted by the adjustment mechanism 4 and the predetermined width W described above will be described.

[0041] <Relationship between surface distance W' and specified width W> As shown in Figure 1 (particularly Figure 1(b)), when the contact surface 3a of the contact body 3 in the width ruler 1 according to the first embodiment contacts the surface M1 side of the surface member M, the surface distance W' can be said to be approximately equal to the above-mentioned predetermined width W. Here, "surface distance W' is approximately equal to the predetermined width W" can be said to mean the case where the thickness of the adhesive sheet S attached to the surface member M is very thin and can be ignored (for example, the thickness of the adhesive sheet S is approximately 0.2 mm), and the surface distance W' is equal to the predetermined width W. Note that, because the actual adhesive sheet S has a predetermined thickness, strictly speaking, it can be said that (surface distance W') = (predetermined width W) + (thickness of the adhesive sheet S), and cases where the thickness of the adhesive sheet S is 1.0 mm or less are also included in the case where "surface distance W' is approximately equal to the predetermined width W."

[0042] <Slide groove 5> As shown in Figures 1 to 5, the slide groove portion 5 is a groove (groove portion) provided in the above-mentioned guide main body 2, and is a groove portion that allows the above-mentioned abutment body 3 to slide approximately along the normal direction of the guide surface 2a (in other words, the direction in which the abutment body 3 moves toward or away from the guide surface 2a). The number of slide groove portions 5 in one width ruler J according to the first embodiment is two or more, and may be only two, or may be three or more. A positioning recess 6, which will be described later, is formed in such a slide groove portion 5, and a fixing shaft portion 7b of a fixing device 7, which will be described later, is inserted slidably through the slide groove portion 5 approximately along the groove length direction.

[0043] The slide groove portion 5 may be provided anywhere in the guide body 2, but for example, if the guide body 2 is a roughly rectangular plate-like body, a total of two may be provided near each end in the longitudinal direction (on the left and right of the slide restraint portion 8 described later), and in this case, the groove length direction of the slide groove portion 5 can be said to be roughly along the short direction of the guide body 2, which is a roughly rectangular plate-like body. In this case, the distance between these two slide grooves 5 (the distance between the center lines of the grooves) is approximately equal to the distance between the two slide fixing insertion holes 3B1 or the distance between the two fixing recesses 3B2 in the contact slide portion 3B of the contact body 3 described above, or it can be said to be approximately equal to the distance between the centers of the two approximately elongated base fixing insertion holes in the contact base portion 3A of the contact body 3. Furthermore, the two slide grooves 5 may be provided not near the ends in the longitudinal direction of the guide body 2, which is a substantially rectangular plate-like body, but near the center in the longitudinal direction (at a position that does not overlap with the slide restraint portion 8 in the approximately left-right center). In addition, as long as the distance between the two slide groove portions 5 is approximately equal to the distance between the two slide fixing insertion holes 3B1, the distance between the two fixing recesses 3B2, or the distance between the centers of the two approximately elongated base fixing insertion holes, the two slide groove portions 5 may be positioned overall to either side in the longitudinal direction of the guide main body 2, which is an approximately rectangular plate-like body (i.e., to the left or right), and as a result, the distances from each longitudinal edge of the guide main body 2, which is an approximately rectangular plate-like body, of the two slide groove portions 5 may be different on the left and right.

[0044] There is no particular limitation on the groove length of each slide groove portion 5 (the length in the short direction of the guide body 2, which is an approximately rectangular plate-like body), but it can naturally be said that it is shorter than the length in the short direction of the guide body 2, which is an approximately rectangular plate-like body.This means that the slide groove portion 5 extends to a position a predetermined distance away from each edge in the short direction of the guide body 2, which is an approximately rectangular plate-like body. The groove width of each slide groove portion 5 is not particularly limited, but may be, for example, a width that allows the fixed shaft portion 7b of the fixing device 7 described later to move within each slide groove portion 5 approximately along the normal direction of the guide surface 2a of the guide main body 2 (the short side direction of the guide main body 2, which is an approximately rectangular plate-shaped body) (specifically, a groove width slightly wider than the diameter of the fixed shaft portion 7b).

[0045] <Positioning recess 6> As shown in FIGS. 1 to 5, the positioning recesses 6 are portions (recessed portions) provided at predetermined intervals in the slide groove portion 5, and serve to position the contact body 3 described above. Here, the "predetermined intervals" when the positioning recesses 6 are provided in the slide groove 5 are not particularly limited, but basically mean that they are provided at equal intervals, and the intervals may be, for example, 5 mm as described above, or may be 1 mm or more and 20 mm or less. More specifically, the lower limit may be 1 mm or more, preferably 2 mm or more, and more preferably 4 mm or more, and the upper limit may be 20 mm or less, preferably 15 mm or less, and more preferably 10 mm or less (a definite value such as 5 mm or 10 mm, or conversely, a small value such as 1 mm or 2 mm). Note that each lower limit of this interval may be combined with any of the upper limits.

[0046] Furthermore, the positioning recesses 6 provided at predetermined equal intervals may be provided alternately (in a zigzag pattern) on one side and the other side of the groove width direction of one slide groove portion 5. In this case, if the positioning recesses 6 are provided at equal intervals of, for example, 10 mm on only one side or the other side of the groove width direction of the slide groove portion 5, and the positioning recesses 6 are provided at equal intervals of 10 mm on the opposite side, shifted by 5 mm in the groove length direction, then it can be said that by using the positioning recesses 6 on both sides in the groove width direction, one slide groove portion 5 has positioning recesses 6 provided at equal intervals of 5 mm. In addition, the spacing between the positioning recesses 6 in the slide groove 5 does not have to be equal. In this case, for example, if a positioning recess 6 is provided on either one side or the other side of the slide groove 5 in the groove width direction at a distance of 7 mm from the end of the slide groove 5 closer to the guide surface 2a in the groove length direction, and a positioning recess 6 is provided on the opposite side at a distance of 12 mm from the end closer to the guide surface 2a, then although the spacing is 7 mm and 5 mm and not equal, it can be said that for special uses, it is easily possible to achieve a surface distance W' (predetermined width W) of 7 mm and 13 mm.

[0047] The shape of such a positioning recess 6 is not particularly limited, but for example, the planar shape may be approximately U-shaped (a shape combining an approximately semicircular portion and an approximately square portion (or an approximately rectangular portion)), and in this case, the diameter of the approximately semicircular portion or the width of the approximately square portion may be approximately the same as or slightly larger than the diameter of the fixing shaft portion 7b of the fixing device 7 described later. Furthermore, the shape of the positioning recess 6 in plan view may be only a substantially semicircular portion or only a substantially square portion, or the shape in plan view may be substantially V-shaped. On the other hand, the side view shape of the positioning recess 6 (as viewed from the side) is not particularly limited, but for example, the planar view shape of the positioning recess 6 may be approximately the same across the thickness direction of the plate-shaped guide body 2 (in other words, it may be formed straight approximately along the thickness direction of the guide body 2), or the size of the positioning recess 6 in plan view may increase (i.e., become flared) or decrease (i.e., become tapered) as it goes from the top surface to the bottom surface of the plate-shaped guide body 2.

[0048] <Fixing fixture 7> As shown in FIGS. 1 to 5, the fixing device 7 is a part provided in the slide groove portion 5, and is a part that can fix the contact body 3 at any position. The specific configuration of the fixing device 7 is not particularly limited, but may include, for example, a fixing screw head 7a that can be gripped and rotated by the user, a fixing shaft portion 7b that extends downward from approximately the center of the underside of the fixing screw head 7a and has a male screw thread formed on the circumferential surface, and a fixing fastener portion 7c such as a hexagonal nut or square nut that can be threaded onto the fixing shaft portion 7b. In this case, by rotating the fixing screw head 7a and tightening the fixing shaft portion 7b and the fixing fastener portion 7c, the movement of the fixing shaft portion 7b within the slide groove portion 5 is restricted (i.e., the movement of the abutment body 3 relative to the guide body 2 is restricted), and the abutment body 3 can be fixed at any position (any surface distance W').

[0049] Alternatively, the fixing device 7 may be fixed at any position not by tightening a screw (no male threads are formed on the circumferential surface of the fixing shaft portion 7b), but by pressing the fixing shaft portion 7b against the inner groove surface of the slide groove portion 5 or the inner recess surface of the positioning recess 6 by operating a cam lever, thereby restricting the movement of the fixing shaft portion 7b within the slide groove portion 5, or in any other manner. The number of such fixing devices 7 is not particularly limited, but may be, for example, two or more, and more specifically, may be provided in each of two or more slide groove portions 5 (i.e., the number of fixing devices 7 may be the same as the number of slide groove portions 5, and one fixing device 7 may be provided in each slide groove portion 5).

[0050] <Slide restraint section 8> As shown in FIGS. 1 to 5, the slide restraining portion 8 is a portion that restrains the slide of the contact body 3 substantially along the normal direction of the guide surface 2a of the guide body 2 described above. The specific configuration of the slide restraint portion 8 is not particularly limited, but may include, for example, a restraint shaft portion 8a that is inserted into the slide insertion hole 3A1 of the above-mentioned abutment body 3 (abutment base portion 3A), a restraint notch portion 8b along which the protruding portion 3A2 surrounding the above-mentioned slide insertion hole 3A1 can move approximately along the longitudinal direction of the restraint shaft portion 8a, and an axis fixing portion 8c that fixes each longitudinal end of the restraint shaft portion 8a on the inner side surface of each longitudinal end of the restraint notch portion 8b. Furthermore, one part of this shaft fixing portion 8c may be a square nut or the like, and the other part may be a screw head. In this case, the part where the other part of the shaft fixing portion 8c and the restraining shaft portion 8a are combined may be a single screw body, and a male screw thread may be formed on the circumferential surface of the restraining shaft portion 8a.

[0051] Alternatively, the slide restraint portion 8 may have any configuration, such as no male threads formed on most of the circumferential surface of the restraint shaft portion 8a (male threads may be formed only near a square nut, which is one part of the shaft fixing portion 8c), or polygonal flange portions such as square or hexagonal flange portions may be provided at both ends of the length of the restraint shaft portion 8a, which has no male threads formed on its circumferential surface at all. The number of such slide restraint portions 8 is not particularly limited, and may be, for example, one or two or more.

[0052] <Connecting plate 9> As shown in FIGS. 1 to 5, when the number of the above-mentioned fasteners 7 is two, the connecting plate 9 is a plate material that connects the fasteners 7 together. The specific configuration of the connecting plate 9 is not particularly limited, but for example, the connecting plate 9 is a plate material having a longitudinal direction, and each end of the longitudinal direction may be formed to be rounded (approximately semicircular) when viewed in a plane, or may be angular. Furthermore, each longitudinal end of the connecting plate 9 may have a through hole formed therein for inserting the fixing shaft portion 7b of the fixing device 7 described above. In this case, when the fixing shaft portion 7b inserted into each through hole moves within the slide groove portion 5 (in other words, when the fixing device 7 itself or the abutment body 3 moves), the connecting plate 9 will also move in accordance with this movement. In this way, by connecting the left and right fixing devices 7 with the connecting plate 9, it can be said that the oscillation (rattle) of the abutment body 3 relative to the guide body 2 can be suppressed ("rattle suppression") compared to when there is only one slide groove, as in Patent Document 1.

[0053] Such connecting plate 9 may be made of a material that can be magnetized by main body magnet 11A in holder main body 11 of holder member 10 (for example, a metal that is attracted to a magnet such as iron, nickel, or cobalt, or the magnet itself). In addition, the connecting plate 9 may have an insertion hole formed at each end in the longitudinal direction, as well as an insertion hole at the middle in the longitudinal direction for inserting the fixed shaft portion 7b. As described above, this insertion hole at the middle portion allows the fixed shaft portion 7b of the fixing device 7 provided in each slide groove portion 5 to be inserted even when the two slide groove portions 5 are provided approximately toward the center in the longitudinal direction of the guide main body 2, which is an approximately rectangular plate-shaped body. In this case, too, it can be said that "rattle suppression" can be achieved.

[0054] <Holder member 10> As shown in FIGS. 4 and 5, the holder member 10 is a member capable of holding the width ruler 1 according to the first embodiment described above. The holder member 10 includes a holder main body 11, which will be described later, and a hook portion 12, which will be described later. The holder member 10 may be provided with a connector 13, which will be described later.

[0055] <Holder main body 11> As shown in FIGS. 4 and 5, the holder main body 11 is a portion that detachably holds the guide main body 2 of the width ruler 1 according to the first embodiment described above. The holder main body 11 may be provided with a main body magnet 11A, which will be described later. The specific configuration of the holder main body 11 is not particularly limited, but for example, it may be a plate-shaped material as a whole, and its planar shape may be, for example, approximately rectangular, approximately square, or other approximately polygonal such as approximately hexagonal or approximately triangular, or may also be approximately circular or approximately elliptical. Alternatively, the guide body 2 may be in the shape of a substantially rectangular parallelepiped, a substantially cubic, a substantially polygonal prism such as a substantially hexagonal prism or a substantially triangular prism, a substantially spherical shape, or a substantially ellipsoid shape. Hereinafter, the holder main body 11 will be mainly described as being a substantially rectangular plate-shaped material.

[0056] The holder main body 11, which is an approximately rectangular plate-shaped material, may have an upper claw portion 11a formed at its upper end portion that hooks onto and holds the upper end portion of the guide main body 2 of the width ruler 1 in the first embodiment from above, and one or more upper claw portions 11a may be formed. On the other hand, the lower end of the holder main body 11, which is a substantially rectangular plate-shaped material, may be formed with a lower claw 11b that hooks onto and holds the lower end of the guide main body 2 of the width ruler 1 according to the first embodiment from below, and one or more lower claws 11b may be formed. It can be said that the lower claw 11b and the above-mentioned upper claw 11a clamp the width ruler 1 (its guide main body 2) from above and below. Furthermore, this lower claw portion 11b may be formed thinner (i.e., more flexible) than the upper claw portion 11a, and it can be said that the flexibility of this lower claw portion 11b makes it possible to hold (remove) the guide body 2 of the width ruler 1 in the first embodiment.

[0057] Furthermore, a holder opening 11c may be provided through the holder main body 11, which is a substantially rectangular plate-shaped material, from approximately the center in the vertical direction to the bottom of the holder main body 11. The shape of this holder opening 11c is not particularly limited, and it may be, for example, substantially rectangular. By providing this holder opening 11c, the entire substantially plate-shaped holder main body 11 becomes more flexible, and it can also be said that this holder opening 11c makes it easier to hold (detachably attach) the guide main body 2 of the width ruler 1. Furthermore, the left and right ends of the holder main body 11, which is a substantially rectangular plate-like material, may be cut out from near the top end to near the bottom end (to have left and right holder cutouts 11d), and the portions where these left and right holder cutouts 11d are located are narrower than other portions of the holder main body 11, which is a substantially rectangular plate-like material, and can be said to provide a barrier to the two fixing devices 7 in the width ruler 1 according to the first embodiment. Note that the holder main body 11, which is a substantially rectangular plate-like material with such left and right holder cutouts 11d, can also be said to have a substantially L-shaped planar shape. Furthermore, when the width ruler 1 of the first embodiment is held in the holder main body 11, which is an approximately rectangular plate-shaped material, the upper surface side of the width ruler 1 is held in an orientation in which it abuts against the front surface of the holder main body 11, which is an approximately rectangular plate-shaped material.

[0058] Additionally, the holder main body 11, which is a substantially rectangular plate-like material, may be provided with a notched rail portion 11e for connection with a connector 13, which will be described later. The specific configuration of the notched rail portion 11e is not particularly limited, but for example, the notched rail portion 11e may be formed by cutting out a substantially rectangular portion downward from approximately the center in the left-right direction of the upper edge of the holder body 11, and the periphery of this notched rail portion 11e (a pair of left and right edge portions of the notched rail portion 11e) may be formed thinner (to form a pair of thin portions 11f) than other portions of the holder body 11, which is a substantially rectangular plate-shaped material. This pair of thin portions 11f will be inserted into a pair of connecting grooves 13e in the connector 13, which will be described later. Furthermore, a predetermined holder recess (e.g., approximately hexagonal or circular) 11h may be formed in the holder main body 11, which is a substantially rectangular plate-shaped material, approximately in the center in the left-right direction below the cutout rail portion 11e, and a holder magnet (neodymium magnet, ferrite magnet, etc.) 11A, which will be described later, may be fitted into this holder recess 11h.

[0059] <Main body magnet 11A> As shown in Figures 4 and 5, the main body magnet 11A is a magnet provided in the holder main body 11 described above, and is capable of magnetizing the width ruler 1 side (in other words, at least some of the components or parts of the width ruler 1) according to the first embodiment described above. At least some of the members or portions of the width ruler 1 that can be magnetized by the main body magnet 11A may be, for example, the above-mentioned connecting plate 9, or may be a bearing member built into the protruding portion 3A2.

[0060] The specific configuration of the main magnet 11A is not particularly limited, but for example, its planar shape may be approximately disk-shaped or approximately hexagonal, and the main magnet 11A may be fitted into the holder recess 11h described above. When the width ruler 1 according to the first embodiment is held in the holder main body 11, which is an approximately rectangular plate-shaped material, this main body magnet 11A can also be said to be in a position corresponding to the connecting plate 9 in the width ruler 1 or the bearing member built into the protruding portion 3A2. Here, if the connecting plate 9 etc. in the width ruler 1 of the first embodiment is made of a metal that is attracted to a magnet, such as iron, the north and south poles can be facing in either direction, but if the connecting plate 9 etc. is also a magnet, when the width ruler 1 is held in the holder main body 11, the main magnet 11A will be inserted in a direction that magnetizes them (so that the surfaces facing each other become north and south poles, or south and north poles).

[0061] <Hook part 12> As shown in FIGS. 4 and 5, the hook portion 12 is a hook-shaped portion attached to the rear side of the holder main body 11 (the side that does not hold the width ruler 1 according to the first embodiment). The hook portion 12 may be substantially U-shaped in side view, and may have a hook magnet 12A, which will be described later. Here, "the hook portion 12 is approximately U-shaped when viewed from the side" does not only mean that the shape of the hook portion 12 when viewed from the side is strictly U-shaped, but also means that of the two ends (arms) 12a, 12b of the U-shape, one arm 12a is slightly longer than the other arm 12b, or the shape of one arm 12a is different from the shape of the other arm 12b (one arm may be slightly bent in the middle or approximately crank-shaped), or the curve of one arm 12a is different from the curve of the other arm 12b, etc. Additionally, when there is a large difference in length between one arm 12a and the other arm 12b, the hook portion 12 can be said to be substantially J-shaped when viewed from the side. Hereinafter, the hook portion 12 will be mainly described as being substantially U-shaped in side view.

[0062] The specific configuration of the hook portion 12, which is approximately U-shaped when viewed from the side, is not particularly limited, but for example, the hook portion 12 may have one or more hook protrusions 12c that protrude inward in the form of horizontal stripes on the inside of each of the two arms 12a, 12b of the approximately U-shaped hook portion 12 when viewed from the side, and it can be said that these hook protrusions 12c prevent the hook portion 12 from slipping out when hooked. Furthermore, in one hook portion 12, one or more hook fixing holes 12d for fixing to the connecting device 13 described later may be provided on the front surface of the hook portion 12 (the side closer to the width ruler 1 of the first embodiment to be held).For example, if four hook fixing holes 12d are provided at equal intervals, it can be said that the relative position of the connecting device 13 to the hook portion 12 can be changed depending on which of the four hook fixing holes 12d the connecting fixing hole 13c in the connecting device 13 is fixed to with the fixing means 13d. These hook fixing holes 12d are provided on one arm portion 12a, and the other arm portion 12b may have a hook insertion hole 12e, through which a tool such as a screwdriver can be inserted, at a position corresponding to the hook fixing hole 12d on the one arm portion 12a.

[0063] In addition, at least one of the tip portions of the two arms 12a, 12b of the hook portion 12 may have an uneven surface (i.e., an anti-slip surface) formed on the inside, and this uneven surface may be in the form of multiple continuous triangular peaks or an approximately semicircular arc. Furthermore, a predetermined hook recess 12f (e.g., approximately hexagonal or approximately circular) may be formed on the outer surface of one or both of the two arms 12a, 12b of the hook portion 12, or a hook gap 12h may be formed on one side end face of the tip, and a hole (so-called air vent hole 12j) may be formed at the bottom of the hook gap 12h that penetrates to the other side end face. A hook magnet 12A, which will be described later, may be fitted into these hook recesses 12f and hook gaps 12h.

[0064] <Hook magnet 12A> As shown in FIGS. 4 and 5, the hook magnet 12A is a magnet that can magnetize the tip ends of two arms 12a and 12b of the completed hook portion 12 that is roughly U-shaped when viewed from the side. The specific configuration of the hook magnet 12A is not particularly limited, but for example, its planar shape may be approximately disk-shaped or approximately hexagonal, and the hook magnet 12A may be fitted into the hook recess 12f or hook gap 12h described above. These hook magnets 12A may be fitted in a direction that magnetizes the tips of the two arms 12a, 12b of the hook portion 12 (so that the surfaces facing each other become north and south poles, or south and north poles), which makes it difficult for the hook portion 12 to come off when attached to a waist tool, belt, etc. by the user.

[0065] <Connector 13> As shown in FIGS. 4 and 5, the connector 13 is provided on the holder member 10 and is a tool for detachably connecting the hook portion 12 to the holder main body 11. The specific configuration of the connector 13 is not particularly limited, but may be, for example, a member that is approximately T-shaped in cross section and has a roughly rectangular flat plate portion 13a and a roughly rectangular narrow flat plate portion 13b that is narrower than the flat plate portion 13a and is stacked approximately in the center of the width of the flat plate portion 13a. In addition, the connector 13 may have holes (connection fixing holes 13c) that are formed through the flat plate portion 13a and the narrow flat plate portion 13b, at approximately the center of the width of the flat plate portion 13a and the narrow flat plate portion 13b, at a predetermined interval, and the connector 13 may be fixed to the front side of the hook portion 12 by using fixing means (such as flat head screws, bolts, nuts, etc.) 13d for the connection fixing holes 13c and the hook fixing holes 12d of the hook portion 12.

[0066] In this way, by fixing the connector 13 to the front side of the hook portion 12, a pair of connection grooves 13e are formed between the flat portion 13a of the connector 13 and the front surface of the hook portion 12, and a pair of thin-walled portions 11f of the holder main body portion 11 described above are inserted and removed into these pair of connection grooves 13e, allowing the hook portion 12 to be freely connected to and detached from the holder main body portion 11. Furthermore, the connector 13 may be fixed to the hook portion 12 by adhesive, welding, fitting, etc. without using the fixing means 13d, and in this case, the connector 13 and the hook portion 12 do not need to have the fixing holes 12d, 13c.

[0067] <Width ruler 1 according to the second embodiment> 6 and 7 show a width ruler 1 according to a second embodiment of the present invention. The biggest difference between the width ruler 1 of this second embodiment and the width ruler 1 of the first embodiment is that it has an abutment surface on the main body side and a guide surface on the object side that moves relative to the main body. In more detail, the width ruler 1 of the second embodiment has an abutment body 22 with an abutment surface 22a that abuts on the surface M1 side of the surface member M, a guide body 23 that is movable relative to the abutment body 22 (abutment surface 22a) and has a guide surface 23a that guides the cutter C, and an adjustment mechanism 24 that adjusts the surface distance W' between the abutment surface 22a of the abutment body 22 and the guide surface 23a of the guide body 23. Furthermore, in the width ruler 1 of the second embodiment, when the abutment surface 22a of the abutment body 22 in the width ruler 1 abuts on the surface M1 side of the surface member M, it becomes approximately equal to the above-mentioned specified width W, and the number of grooves is two or more, which is the same.

[0068] Other differences include that the slide groove 25, unlike the slide groove 5 in the width ruler 1 according to the first embodiment, is a groove provided in the contact body 22 and allows the guide body 23 to slide approximately along the normal direction of the contact surface 22a; the positioning recesses 26 are recesses provided at predetermined intervals in the slide groove 25 and position the guide body 23; and the fixing device 27 is a device provided in the slide groove 25 and can fix the guide body 23 at any position. Furthermore, the width ruler 1 according to the second embodiment may have three slide groove portions 25, and may also have one fixing device 27 (or only one fixing screw head 27a but three fixing shaft portions 27b and fixing fastener portions 27c), or the corners of the approximately rectangular guide body 2 may not be cut out diagonally, or there may be no slide restraint portion 8, or there may be no holder member 10, or there may be no connecting plate 9, etc. On the other hand, the width ruler 1 according to the second embodiment is provided with a squeegee portion 28 (described later) that was not present in the width ruler 1 according to the first embodiment, and the guide body 23 (described later) is capable of "sliding diagonally." Therefore, in the following, the squeegee portion 28 and the "diagonal slide" will be mainly explained assuming that the contact body 22 is a substantially rectangular plate-shaped material.

[0069] <Squeegee part 28> As shown in Figures 6 and 7, the squeegee portion 28 is a portion provided on the side end surface 22C opposite to the side end surface 22A on which the abutment surface 22a is provided, of the abutment body 22, which is a substantially rectangular plate-shaped material. The squeegee portion 28 can be said to be a part used as a squeegee or spatula, which is used to press the adhesive sheet S approximately uniformly when attaching the adhesive sheet S to the surface member M, and to push out any air bubbles that have become trapped between the adhesive sheet S and the surface member M. The specific configuration of the squeegee portion 28 is not particularly limited, but for example, the tip (opposite side end surface 22C) of the squeegee portion 28 may be formed thinner than other parts of the abutment body 22, or a felt fabric may be attached to the tip side. As a result, the width ruler 1 of the second embodiment can be used not only as a cutter guide (to guide the cutter C, which cuts the edge of the adhesive sheet S leaving only a specified width W), but also as a squeegee, allowing the user to perform a series of tasks without the need to change hands.

[0070] <"Diagonal slide" of guide body 23> As shown in Figures 6 and 7, in the width ruler 1 according to the second embodiment, a slide groove portion 25 is formed so that the guide body 23 can slide in both the longitudinal and lateral directions of the abutment body 22, which is a substantially rectangular plate-shaped material. The premise is that the abutment body 22, which is an approximately rectangular plate-shaped material, has abutment surfaces 22a on each of two adjacent side end faces 22A, 22B (i.e., two side end faces sandwiching a corner of the abutment body 22, which is an approximately rectangular plate-shaped material). The guide body 23 is slidable substantially along the normal directions of the two contact surfaces 22a.

[0071] Incidentally, the specific configuration of the slide groove portion 25 is not particularly limited, but for example, one or more of the positioning recesses 26 provided in the slide groove portion 25 extend a predetermined distance in a direction approximately perpendicular to the groove length direction of the slide groove portion 25 (forming orthogonal positioning recesses 26'), and the fixed shaft portion 27b of the fixing device 27 (the part corresponding to the fixed shaft portion 7b in the fixing device 7 described above) is inserted into this orthogonal positioning recess 26', and when this is inserted and tightened with the fixing device 27, the movement of the fixed shaft portion 27b (i.e., the movement of the guide body 23 relative to the abutment body 22) is restricted, so that the guide body 23 slides a predetermined surface distance W' in the longitudinal direction relative to the abutment body 22, which is an approximately rectangular plate-shaped material, and also slides a predetermined surface distance W' in the short direction thereof. As a result, it can be said that the guide body 23 slides diagonally relative to the abutment body 22, which is an approximately rectangular plate-shaped material.

[0072] <Other configurations> The other configurations, effects, and usage modes of the width ruler 1 of the second embodiment are basically the same as those of the width ruler 1 of the first embodiment described above, but the following will particularly mention the object side (i.e., the guide body 23) that moves relative to the main body. 6 and 7, the guide body 23 is an object that is movable relative to the contact surface 22a of the contact main body 22 and has a guide surface 23a that guides the cutter C. There are no particular limitations on the specific configuration of the guide body 23, but the entire body may be a thin plate made of metal such as iron. Although the guide body 23 is a thin plate, because it is made of metal, it can be said that there is no problem in guiding the cutter C. Furthermore, when comparing the second embodiment with the first embodiment, although the abutment surface 22a is provided on either the main body or an object that moves relative to the main body, it can be said to be similar to the first embodiment in terms of the abutment surface 3a of the above-mentioned abutment body 3, the fact that it "abuts on the surface M1 side of the plane member M," whether it is substantially flat, the material of the abutment surface, etc. Similarly, when comparing the second embodiment with the first embodiment, although there is a difference in whether the guide surface 23a is provided on the main body or on an object that moves relative to the main body, it can be said that it is similar to the first embodiment in terms of whether the guide surface 2a of the above-mentioned guide main body 2 is approximately flat or not, the number of guide surfaces provided on one guide body 23, and the fact that if the guide body 23 is made of metal, the guide surface 23a can be said to have been hardened, etc.

[0073] <Other> The present invention is not limited to the above-described embodiment. The individual components of the width ruler 1 and the overall structure, shape, and dimensions can be modified as appropriate in accordance with the spirit of the present invention. Regardless of whether the width ruler 1 is the first embodiment or the second embodiment, the following can be said. The number of fixing devices 7 may be one. The adjustment mechanism 4 does not necessarily have to include the slide restraint portion 8. The shape of the guide body 2 in plan view does not have to be substantially rectangular, and the corners of the guide body 2 do not have to be cut out obliquely. The width ruler 1 does not necessarily have to have the holder member 10, and even if it has the holder member 10, the holder member 10 does not necessarily have to have the holder main body portion 11 or the hook portion 12. The holder main body 11 may not be provided with a main body magnet 11A, or the hook portion 12 may not be approximately U-shaped when viewed from the side, or may not be provided with a hook magnet 12A even if it is approximately U-shaped when viewed from the side. The holder member 10 does not necessarily have to include the connector 13 .

[0074] The contact body 22 does not have to be a substantially rectangular plate-shaped material, and even if it is a substantially rectangular plate-shaped material, it does not have to be provided with a squeegee portion 28, or the slide groove portions 25 may not be formed in a shape that allows the guide body 23 to slide substantially along the two normal directions.
