Description

[Technical Field]

[0001] The present invention relates to a template for drawing lines using a writing implement, and more particularly to a template for creating a table made up of parallel lines extending vertically and horizontally using a writing implement. [Background technology]

[0002] Tables (for example, calendars for writing schedules, various aggregated results, matrix-type thinking tools, etc.) are often created to visually display schedules, statistical results, thoughts, and various other information. When ready-made calendars or address books are not available, such tables are usually created by hand using a ruler on memo paper or notebook.

[0003] When creating such tables, if you want to create a neat table, it takes time and effort to carefully position a ruler in the correct position, or if you skip that time and create the table freehand, the table often ends up looking rough. For these reasons, templates (sometimes called template rulers) have been proposed for easily creating tables of a predetermined size, and for example, templates shown in Non-Patent Documents 1 and 2 already exist.

[0004] Such templates are typically made of a plastic sheet or cardboard about the size of a notebook or diary, with several to about ten slit holes or through holes of the same length and parallel to one another formed in the plastic sheet or cardboard of the template.

[0005] Here, in the case of the templates described in Non-Patent Documents 1 and 2, a table can be created by first drawing multiple parallel lines on a piece of paper using the template, and then using another set of multiple parallel slit holes on the same template but with an angle changed by 90 degrees, drawing new multiple parallel lines perpendicular to the initial parallel lines. [Prior art documents] [Non-patent literature]

[0006] [Non-Patent Document 1] Waki Stationery, "I made a planner template", [online], Japan, Instagram, April 12, 2019, Internet<URL:https: / / www.instagram.com / p / BwJNWScHsul / > (Retrieved April 8, 2020) [Non-patent document 2] Waki Bungu, "Waki Bungu Original Diary Template [Set of 4]", [online], Japan, https: / / www.wakibungu.com / c / diary / set-0019 (Retrieved July 29, 2024) Summary of the Invention [Problem to be solved by the invention]

[0007] However, the templates in Non-Patent Documents 1 and 2 have a set of parallel slit holes formed so that they fit within a single plastic sheet or cardboard. Therefore, the external size of the table that can be drawn is inevitably determined by the dimensions of the parallel slit holes, and the maximum size of the table is limited by the size of the plastic sheet or cardboard. Furthermore, within this dimension, the table is divided according to the number of parallel slit holes. Therefore, depending on the number of divisions, while it may be possible to write simple numbers and letters in the table, it may not be suitable for writing numbers or letters of several to several dozen characters.

[0008] On the other hand, for calendars on which schedules can be written, various types of tally results, matrix-type thinking tools, and the like, it may be desirable to be able to write, for example, a few to a dozen characters in each square. In contrast, for conventional templates, increasing the size of the template itself, i.e., the size of the plastic sheet or cardboard, can increase the size of each square in the table and the number of characters that can be written. However, in this case, the convenience of being able to easily carry the template in a small notebook (e.g., A6-sized notebook) or planner is sacrificed.

[0009] [Object of the Invention] The present invention has been made to solve the above-mentioned inconveniences, and its purpose is to provide a template that allows for the quick creation of tables divided into vertically and / or horizontally arranged squares, and also allows the table to be easily expanded as needed. [Means for solving the problem]

[0010] In order to achieve the above object, the present invention provides a template for creating a table divided into vertical and / or horizontal grids on a sheet of paper and expanding it as needed, the template comprising: A plate-shaped template body is provided, the template body includes a square central region and an outer peripheral region surrounding the square central region, and the square central region is virtually divided into N×N unit square grids by N+1 horizontal grid lines (N is an integer of 2 or greater) extending parallel to and at equal intervals in the horizontal direction and N+1 vertical grid lines the same length as the horizontal grid lines and extending parallel to and at equal intervals in the vertical direction, the size of the unit square grids corresponding to the size of the smallest square that can be represented in the table, The template body includes: N+1 slit holes arranged along the entire length of each of either the N+1 horizontal grid lines or the N+1 vertical grid lines; a rotational direction positioning means for positioning the template body at an arbitrary position on the paper surface in a new orientation when the template body is repositioned to a new orientation rotated by ±90 degrees from a current orientation around a center point of the square central region as a rotation center; and a plane orthogonal direction positioning means for positioning the template body at a new position shifted by N unit square grids from the arbitrary position in a direction in which the table is to be expanded; Equipped with The plane-orthogonal direction positioning means is configured as a template including, in the outer peripheral region, a first V-shaped groove provided at a position away from one of N+1 points distributed at equal intervals along the entire length of one outer grid line constituting one side of the periphery of the square central region, in a direction perpendicular to the one outer grid line, toward the outer periphery of the template body by a distance equivalent to one unit square grid. [Effects of the Invention]

[0011] Since the present invention is configured in this manner, first, N straight lines each having a length equivalent to N unit square grids and spaced apart by one unit square grid can be drawn using the N+1 slit holes provided in the template body, and then the template body can be repositioned by rotating it 90 degrees using the rotation direction positioning means, after which N+1 straight lines can be drawn again using the N+1 slit holes, thereby quickly creating a table having N x N squares. Furthermore, if necessary, the plane orthogonal direction positioning means can be used to reposition the template body in the direction in which the table is desired to be expanded, shifting it by N unit square grids, i.e., the length of the slit holes, and N+1 straight lines can be drawn using the N+1 slit holes.Furthermore, the rotational direction positioning means can be used again to reposition the template body in an orientation rotated 90 degrees, and then N+1 straight lines can be drawn again using the N+1 slit holes, thereby quickly expanding the initially created table with N×N squares to an N×N square next to it (in other words, an N×2N table can be quickly created). Furthermore, this expansion can be repeated as necessary, and it is possible to create not only the Nx2N tables mentioned above, but also 2Nx2N, 2Nx3N, 3Nx3N, etc. [Brief explanation of the drawings]

[Figure 10] FIG. 10 is a plan view showing the front side of a template according to a third embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] The configuration of a template 10 according to several embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the dimensions of various components and the relationships between components depicted in each drawing are not necessarily proportional to actual size, and some components may be enlarged or omitted as necessary to clearly show each characteristic part.

[0014] [First embodiment] First, a plate-shaped template 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a plan view showing the front side (surface) of the template 1.

[0015] Template 1 shown in Figure 1 is a template that allows you to create a table divided into vertically and / or horizontally arranged squares by drawing multiple parallel lines perpendicular to the vertical and / or horizontal directions on the surface of a piece of paper placed underneath it using a writing instrument (e.g., a ballpoint pen, a mechanical pencil, a lead pencil, etc.), and this table can be extended to the adjacent side as needed.

[0016] In this embodiment, the grids of the table are described as square grids, but are not limited to this. For example, two horizontally adjacent square grids may be combined into one rectangular grid by not drawing the grid boundary lines between them. In this specification, the "square grid" and the "rectangular grid" are also referred to as the "smallest grid that can be represented in a table."

[0017] Template 1 in this embodiment is described as a template that first creates a table consisting of 3 rows and 3 columns of square grids (hereinafter also referred to as a "3x3 table") and, if necessary, can expand the 3x3 table adjacent to the current (original) 3x3 table that has been created (in other words, can create a new, continuous 3x3 table), but is not limited to this. Templates according to other embodiments of the present invention may be templates for creating and expanding a table with 4 rows and 4 columns of square grids, a table with 2 rows and 2 columns of square grids, etc.

[0018] Furthermore, the template according to the present invention can be generalized to create and expand a table having a square grid of N rows and N columns. For the time being, the following description will be given in terms of a generalized table configured as a square grid of N rows and N columns, but as occasionally indicated in parentheses, this embodiment is for N=3.

[0019] The present invention can be a template for creating a table having N×N square cells when the number of square cells in the table is generalized as N (N is a natural number equal to or greater than 2. In this embodiment, N=3). However, N may have an upper limit, and for example, the upper limit of N may be determined based on the two-dimensional size of the template 1 and the minimum size of one cell (for example, the size derived from the number of characters desired to be written in the cell, for example, several to 10 or so characters per cell) (specific dimensions will be described later).

[0020] In this embodiment, the template 1 includes a thin, plate-like template body 10 having a constant thickness. The template body 10 includes a square central region (hereinafter also referred to as the "square central region") at its center and an outer periphery (hereinafter also referred to as the "outer periphery region") surrounding the square central region. The entire square central region is virtually divided into N×N unit square grids (N=3, i.e., 3×3 unit square grids) by N+1 horizontal grid lines (where N is an integer of 2 or greater; in this embodiment, N=3, i.e., 4) extending parallel to each other at equal intervals in the horizontal direction (the left-right direction on the paper in FIG. 1 ) and N+1 vertical grid lines (N=3, i.e., 4) having the same length as the horizontal grid lines and extending parallel to each other at equal intervals in the vertical direction (the up-down direction on the paper in FIG. 1 ).

[0021] Here, the square central region is the region indicated by a thick square line in the center of the template body 10 in FIG. 1. Furthermore, horizontal and vertical grid lines are represented by two-dot chain lines in FIG. 1. Note that in this specification, a "unit grid" refers to the smallest unit area (cell) surrounded by the horizontal and vertical grid lines. Furthermore, the size of one of the aforementioned "square grids" is equal to the size of one unit grid, and the size of one of the aforementioned "rectangular grids" is equal to the size of two unit grids.

[0022] The template body 10 has N+1 slit holes (N=3 in this embodiment, i.e., four slit holes) within a square central region. More specifically, the N+1 slit holes are arranged within the square central region along the entire length of each of the N+1 (four in this embodiment) grid lines of either the N+1 (four in this embodiment) virtual horizontal grid lines or the N+1 (four in this embodiment) virtual vertical grid lines. As is clear from FIG. 1 , the length of each slit hole is N unit square grids (N=3 in this embodiment, i.e., three unit square grids), and the intervals between the center lines of adjacent slit holes are equal, i.e., one unit square grid.

[0023] From here on, for simplicity's sake, we will only explain the example of this embodiment where N=3, but the following explanation can also be applied to the general case where the number of square cells in the table is N, as described above.

[0024] As described above, the template body 10 has four slits 11, 12, 13, and 14 in the central region. Each of the slits 11 to 14 has a length corresponding to three squares on the front, i.e., three unit grids. The slits 11 to 14 are arranged in parallel at equal intervals.

[0025] The above-mentioned grid is depicted as two types of grid in Fig. 1. One is a "grid grid G" of the entire area with 5 rows and 5 columns, and the other is a "grid grid G' of the central area with 3 rows and 3 columns, indicated by thick lines and located further inside the grid grid G. The former is mainly used to indicate the positions of the V-shaped grooves, which will be described later, and the latter is mainly used to explain the arrangement of the slit holes 11, 12, 13, and 14, and corresponds to the range of the central area.

[0026] As shown in the figure, the entire square grid G ​​described above is composed of six equally spaced, parallel vertical grid lines V0, V1, V2, V3, V4, and V5, each having a length equivalent to five unit square grids, extending in the vertical direction, and six equally spaced, parallel horizontal grid lines H0, H1, H2, H3, H4, H5, and H6, each having a length equivalent to five unit square grids, extending in the direction perpendicular to the plane. The smallest unit of the square grid G ​​is the smallest square grid described above. The vertical grid lines V0 to V5 and the horizontal grid lines H0 to H6 are virtual lines and do not actually need to be visibly attached to the template body 10.

[0027] On the other hand, the square grid G' is shown within a square PQRS area with vertices P, Q, R, and S. Here, point P is the intersection of horizontal grid line H1 and vertical grid line V1, point Q is the intersection of vertical grid line V1 and horizontal grid line H4, point R is the intersection of vertical grid line V4 and horizontal grid line H4, and point S is the intersection of vertical grid line V4 and horizontal grid line H1. These may be expressed in coordinate format herein as point P(V1,H1), point Q(V1,H4), point R(V4,H4), and point S(V4,H1) (the same applies when referring to points other than these points).

[0028] The central region, a square PQRS, includes four equally spaced, parallel horizontal grid lines v1, v2, v3, and v4, each having a length equivalent to three unit grid squares, and four equally spaced, parallel vertical grid lines h1, h2, h3, and h4, each having a length equivalent to three unit grid squares. Point O is indicated at the geometric center of the square PQRS. This point is also the center point of the central region. In FIG. 1, the four slit holes 11, 12, 13, and 14 are arranged along the entire length of each of the horizontal grid lines h1, h2, h3, and h4, respectively. However, this is not limiting. The four slit holes 11, 12, 13, and 14 may also be arranged along the entire length of each of the four vertical grid lines v1, v2, v3, and v4, respectively.

[0029] Next, the individual configurations of the slit holes 11, 12, 13, and 14 will be described. 1 are elongated holes that penetrate the template body 10 separately. Each of the slit holes 11, 12, 13, and 14 is defined by a pair of opposing vertical walls that extend in the length direction of the slit hole with a predetermined gap width therebetween, and end walls that are formed continuously with the vertical walls on both ends of the vertical walls. In this embodiment, the vertical walls and end walls are perpendicular to the front and back surfaces of the template body 10, and the heights of the face walls and end walls are equal to the plate thickness of the template body 10.

[0030] In addition, the end points indicating the ends of each slit hole 11, 12, 13, and 14 are respectively indicated by symbols 11a and 11c, symbols 12a and 12c, symbols 13a and 13c, and symbols 14a and 14c, and these correspond to pen tip movement restriction positions 11b and 11d, 12b and 12d, 13b and 13d, and 14b and 14d, which restrict the movement of the pen tip N of a writing instrument when inserting the pen tip N (see Figure 2(A)) into the slit hole and drawing a line.

[0031] In actual use, the pen tip N of a writing implement is inserted into each of the slit holes 11, 12, 13, and 14 in turn, and then the pen tip N is moved along the entire length of the slit hole while being in contact with at least a part of the vertical wall (for example, the upper edge of the vertical wall). This allows a straight line of a length equivalent to three square grids to be drawn.

[0032] The lengths of the slits 11, 12, 13, and 14 are preferably configured to fit within the short sides of a planner, B5 notebook, or A6 notebook, and are preferably, for example, approximately 65 mm, approximately 80 mm, or approximately 95 mm, respectively. These dimensions allow the sheet to be carried around by clipping it into a small planner or notebook, and, if necessary, it is also possible to create expanded tables such as 9x9 tables on relatively large paper or notebooks such as A4, B4, and A3 sizes.

[0033] The slit width of each of the slit holes 11, 12, 13, and 14 is the same throughout the entire length of each slit hole, and is, but is not limited to, approximately 0.8 mm to approximately 2.3 mm. This slit width may be designed based on the thickness of the template body 10 and the type of writing instrument intended for use. For example, if the template body 10 is 1 mm thick and is intended for use with a general pen, the slit width may be approximately 0.6 mm to 2.0 mm, and preferably approximately 1.0 mm to 1.2 mm. While narrowing the slit width can reduce distortion of the table to be created, in the present invention, as described below, when using the template to expand a table, it may be necessary to visually introduce some of the marks and / or lines drawn on the paper into the slit holes. Therefore, maintaining a relatively wide slit width makes it easier to capture some of the marks and / or lines, which may shorten the time required to create the table.

[0034] Next, the above-mentioned outer peripheral portion (or outer peripheral region) will be described. As shown in FIG. 1, the template body 10 has an outer peripheral portion (a region outside the square grid G' of the central region) that surrounds the central region. The outer peripheral portion includes an outer periphery 16 at its outermost portion. The outer peripheral portion also has ears in a region outside the entire square grid G. In this embodiment, the four corners of the outer periphery 16 are chamfered to form chamfered portions 17. This eliminates sharp edges from the template body 10, improving safety. However, this is not limiting. All or part of the chamfered portions 17 may be omitted (see FIG. 4(A)).

[0035] The template body 10 has V-shaped grooves 21, 22, 23, and 24 (a first V-shaped groove group), 31, 32, 33, and 34 (a second V-shaped groove group), 41, 42, 43, and 44 (a third V-shaped groove group), and 51, 52, 53, and 54 (a fourth V-shaped groove group) on the outer periphery. Each of the V-shaped grooves 21 to 24 is provided on the outer periphery 16. More specifically, each V-shaped groove 21 is smoothly connected to the outer periphery 16 by a pair of cut surfaces 21 a. However, the V-shaped grooves do not necessarily need to be smoothly connected to the outer periphery 16. The outer periphery 16 may have various other shapes, such as an irregular contour shape, as shown in FIG. 4(B), as long as the V-shaped grooves (more specifically, the valleys of the V-shaped grooves), which will be described next, are present in appropriate positions.

[0036] Next, we will first provide an overview of the locations of these V-shaped grooves. As can be seen from Figure 1, V-shaped grooves 21, 22, 23, and 24 are located at points (V0, H1), (V0, H2), (V0, H3), and (V0, H4), respectively, on one side of the left side of the square grid G ​​in a planar view. These points are located at points that are spaced outward from the four nearest points that are equally spaced along the entire length of one side of the peripheral boundary of the square central region (square PQRS) (i.e., one side of the outer grid frame of the square grid G' in the central region) PQ by a distance equivalent to one unit square.

[0037] The other V-shaped grooves 31, 32, 33, and 34, V-shaped grooves 41, 42, 43, and 44, and V-shaped grooves 51, 52, 53, and 54 are also located at points one unit grid square away from the four points located equally spaced along the entire length of each of the sides QR, RS, and SP corresponding to the nearest square PQRS (i.e., sides of the outer grid frame of the rectangular grid G' in the central region).

[0038] In particular, in this embodiment, V-grooves 21, 22, 23, and 24 lie on horizontal grid lines H1, H2, H3, and H4, respectively, and V-grooves 41, 42, 43, and 44 also lie on horizontal grid lines H1, H2, H3, and H4, respectively.

[0039] Next, the placement of each V-groove will be described in more detail. In this embodiment, for example, the V-shaped groove 21 included in the first V-shaped groove group 20 is provided at one of four points (i.e., points (V1, H1), (V1, H2), (V1, H3), and (V1, H4)) that are equally spaced along the entire length of the outer grid line PQ that constitutes one side of the outer grid frame (i.e., square PQRS) of the square grid G′ in the central region, for example, at point U(V0, H1), which is a position that is away from point (H1, V1) by a distance equivalent to one unit square square toward the outer periphery of the template body in a direction perpendicular to the outer grid line PQ (i.e., in the direction in which the horizontal grid H1 extends leftward on the paper).

[0040] The V-shaped groove 24 is provided at another one of four points that are equally spaced along the entire length of the outer grid line PQ that forms one side of the outer grid frame (i.e., the square PQRS) of the square grid G' in the central region, for example, at point V(V0,H4), which is located at a distance equivalent to one unit square toward the outer periphery of the template body in a direction perpendicular to the outer grid line PQ from point (V1,H4).

[0041] Similarly, the remaining V-shaped grooves 22 are provided at any one of the remaining four points equally spaced along the entire length of the outer grid line PQ, for example, at point V(V0,H2), which is located at a distance equivalent to one unit square toward the outer periphery of the template body in a direction perpendicular to the outer grid line PQ from point (V1,H2).

[0042] The remaining V-shaped grooves 23 are provided at the remaining one of the four points equally spaced along the entire length of the outer grid line PQ, for example, at point V(V0,H3), which is located at a distance equivalent to one unit square towards the outer periphery of the template body in a direction perpendicular to the outer grid line PQ from point (V1,H3).

[0043] In this embodiment, the first V-shaped groove group 20 includes four V-shaped grooves, but is not limited to this. Preferably, the first V-shaped groove group 20 includes two V-shaped grooves, and more preferably, these two V-shaped grooves are V-shaped groove 21 and V-shaped groove 24. This is because, when the V-shaped groove 21 and the V-shaped groove 24 function as part of the first and plane-orthogonal direction positioning means described below, the greater the distance between them, the more accurate the positioning can be.

[0044] In addition, in this embodiment, the V-shaped grooves 31 included in the second V-shaped groove group 30, the V-shaped grooves 41 included in the third V-shaped groove group 40, and the V-shaped grooves 51 included in the fourth V-shaped groove group 50 can be located at positions rotated 90 degrees, 180 degrees, or 270 degrees clockwise, respectively, from the position (point (v1, h1)) of the V-shaped groove 21 included in the first V-shaped groove group 20, with the center point O of the square grid as the rotation center.

[0045] Furthermore, the V-shaped grooves 32 included in the second V-shaped groove group 30, the V-shaped grooves 42 included in the third V-shaped groove group 40, and the V-shaped grooves 52 included in the fourth V-shaped groove group 50 can be located at positions rotated 90 degrees, 180 degrees, or 270 degrees clockwise, respectively, from the position (point (v1, h2)) of the V-shaped groove 24 included in the first V-shaped groove group 20, with the center point O of the square grid as the rotation center.

[0046] Furthermore, the V-shaped grooves 33 included in the second V-shaped groove group 30, the V-shaped grooves 43 included in the third V-shaped groove group 40, and the V-shaped grooves 53 included in the fourth V-shaped groove group 50 can be located at positions rotated 90 degrees, 180 degrees, or 270 degrees clockwise, respectively, from the position (point (v1, h3)) of the V-shaped groove 24 included in the first V-shaped groove group 20, with the center point O of the square grid as the rotation center.

[0047] Similarly, the V-shaped grooves 34 included in the second V-shaped groove group 30, the V-shaped grooves 44 included in the third V-shaped groove group 40, and the V-shaped grooves 54 included in the fourth V-shaped groove group 50 can be located at positions rotated 90 degrees, 180 degrees, or 270 degrees clockwise, respectively, from the position (point (v1, h4)) of the V-shaped groove 24 included in the first V-shaped groove group 20, with the center point O of the square grid as the rotation center.

[0048] Next, the individual structures of the V-shaped grooves will be described. Figures 4(A) to 4(E) are enlarged partial views of various types of V-shaped grooves. Below, we will explain V-shaped groove 21, but the same applies to other V-shaped grooves.

[0049] The V-shaped groove 21 shown in FIG. 3A(A) is the V-shaped groove 21 shown in FIG. 1. The V-shaped groove 21 is configured by cutting out a portion of the outer periphery 16 of the template body 10 in a V-shape. This V-shaped groove 21 has a pair of cutout surfaces 21a, 21a whose width linearly narrows from the outer periphery 16 toward the innermost side, and these cutout surfaces 21a, 21a can guide the pen tip N of the writing instrument toward the innermost side. The cutout surfaces 21a, 21a are vertical surfaces. The opening angle of the V-shaped groove is an acute angle, for example, approximately 60 degrees. At the deepest part (innermost part) of the V-shaped groove 21, there is a valley 21b where the cutout surfaces 21a, 21a intersect. This valley 21b serves as a reference point for the position of the V-shaped groove when identifying the position of the V-shaped groove.

[0050] 4(B) may have a pair of perpendicular cut surfaces 21a', 21a' with an opening angle of obtuse (e.g., about 120 degrees). This opening angle may be further widened as long as the tip of the pen tip N can be supported in a fixed position at the position of the valley 21b'.

[0051] 4(C) may have a pair of inclined cutout surfaces 21c, 21c that can guide the pen tip N, and a valley 21d where these surfaces intersect, instead of a pair of perpendicular cutout surfaces. The adoption of inclined cutout surfaces 21c, 21c has the advantage of making it easier to introduce the pen tip N.

[0052] 4(D) has a pair of vertical passage walls 21e, 21e that connect a pair of vertical cut surfaces 21f, 21f connected by a valley 21g to the outer periphery 16, 16, and these can guide the pen tip N to the innermost side. The passage walls 21e, 21e are not limited to the shape shown in the figure and may be curved and / or non-parallel.

[0053] 4(E) may have a triangular hole 21h in its outer periphery. This triangular hole 21h may have a pair of perpendicular cutout surfaces 21i, 21i that penetrate from the front surface to the back surface and that can guide the pen tip N, and a valley 21j where they intersect.

[0054] Next, the rotational direction positioning means will be described. In this embodiment, the template body 10 is provided with a rotational direction positioning means in order to create a table consisting of 3 rows and 3 columns of squares (hereinafter also referred to as a "3x3 table").

[0055] This rotational direction positioning means is a rotational direction positioning means for positioning the template body 10 at any position on the paper surface in a new orientation when the template body 10 is repositioned in a new orientation rotated ±90 degrees from its current orientation around the center point of the square central area as the rotation center.

[0056] More specifically, the rotational direction positioning means is for positioning the template body 10 in a second orientation at the first position when the template body 10 is repositioned from a first orientation at the first position before repositioning to a second orientation at the first position after repositioning so that the hole ends 11a and 11c and 14a and 14c of the two outer slit holes 11 and 14 of the four slit holes 11 to 14 of the template body 10 arranged in a first orientation at the first position move to positions rotated 90 degrees or -90 degrees in the same rotational direction with the center point O of the square grid as the rotation center (for example, hole end 11a moves to the position where hole end 14a was located immediately before repositioning, 14a moves to the position where hole end 14c was located immediately before repositioning, 14c moves to the position where hole end 11c was located immediately before repositioning, and 11c moves to the position where hole end 11a was located immediately before repositioning).

[0057] In this embodiment, the rotational positioning means is composed of two groove pairs, where one V-shaped groove of each pair is spaced apart from the other V-shaped groove at positions separated by an angular difference of 90 degrees in clockwise or counterclockwise rotation around the center point O of the square grid G.

[0058] One V-shaped groove of each groove pair is used to create a mark on the paper by placing the tip of a writing implement against it, and the other V-shaped groove of each groove pair is used to align with the created mark. Each "one V-shaped groove" is located at a position rotated 90 degrees or -90 degrees in the same rotational direction relative to the other V-shaped groove, with the center point O of the square grid as the rotation center. This allows the mark created using one V-shaped groove of the first set to be captured by the other V-shaped groove of the first set, and the mark created using one V-shaped groove of the second set to be captured by the other V-shaped groove of the second set, thereby identifying the second orientation at the second position of the template body 10 and positioning it.

[0059] 1, for example, the first V-groove is located at the position described above, and the third, fifth, and seventh V-grooves are located at positions rotated 90 degrees, 180 degrees, and 270 degrees from the first V-groove around the center point O of the grid. The second V-groove is located at the position described above, and the fourth, sixth, and eighth V-grooves are located at positions rotated 90 degrees, 180 degrees, and 270 degrees from the second V-groove around the center point O of the grid. In this case, the two groove pairs may be any two of the following: a groove pair consisting of the first and third V-shaped grooves (e.g., V-shaped grooves 21 and 31); a groove pair consisting of the third and fifth V-shaped grooves (e.g., V-shaped grooves 31 and 41); a groove pair consisting of the fifth and seventh V-shaped grooves (e.g., V-shaped grooves 41 and 51); a groove pair consisting of the seventh and first V-shaped grooves (e.g., V-shaped grooves 51 and 21); a groove pair consisting of the second and fourth V-shaped grooves (e.g., V-shaped grooves 24 and 34); a groove pair consisting of the fourth and sixth V-shaped grooves (e.g., V-shaped grooves 34 and 44); a groove pair consisting of the sixth and eighth V-shaped grooves (e.g., V-shaped grooves 44 and 54); and a groove pair consisting of the eighth and second V-shaped grooves (e.g., V-shaped grooves 54 and 24).

[0060] As a more specific example, the two groove pairs shown in FIG. 1 are as follows: Example 1: Two groove pairs including a first groove pair consisting of a V-shaped groove 21 located at point U and a V-shaped groove 31 located at point W, and a second groove pair consisting of a V-shaped groove 24 located at point V and a V-shaped groove 34 located at point X. Example 2: Two groove pairs including a first groove pair consisting of a V-shaped groove 21 located at point U and a V-shaped groove 31 located at point W, and a second groove pair consisting of a V-shaped groove 31 located at point W and a V-shaped groove 41 located at point Y. Example 3: Two groove pairs including a first groove pair consisting of a V-shaped groove 24 located at point V and a V-shaped groove 34 located at point X, and a second groove pair consisting of a V-shaped groove 31 located at point W and a V-shaped groove 41 located at point Y. Example 4: Two groove pairs including a first groove pair consisting of a V-shaped groove 21 located at point U and a V-shaped groove 31 located at point W, and a second groove pair consisting of a V-shaped groove 41 located at point Y and a V-shaped groove 51 located at point Z.

[0061] In this embodiment, the rotational direction positioning means is configured with the two groove pairs described above. However, the present invention is not limited to this. When the template body 10 is made of a transparent or translucent material, auxiliary lines for positioning may be formed on the template body 10 to serve as the rotational direction positioning means. For example, auxiliary lines may be visibly formed on the transparent or translucent template body 10 along the entire lengths of at least one, preferably at least two, grid lines PQ, P'Q', S'R', and SR that are perpendicular to the slits 11, 12, 13, and 14 of the square grid G' shown in FIG. 1 . This allows the auxiliary lines on the template body 10 to be aligned with at least one, preferably two, of the four parallel lines drawn when the template body 10 is positioned in a first orientation at a first position. This allows the rotational direction positioning means using the auxiliary lines to identify and position the template body 10 in a second orientation at the first position. These auxiliary lines for rotational direction positioning may also be used for positioning in the direction perpendicular to the plane, if necessary. For example, when a slit hole is used to capture a mark, the mark can be captured at the position of an auxiliary line, and used for positioning in the direction perpendicular to the plane.

[0062] Next, the means for positioning in the direction perpendicular to the plane will be described. The plane orthogonal direction positioning means is used to position the template body 10 at a new position (e.g., a second position) that is shifted by N unit grid squares from an arbitrary position (e.g., a first position) in the direction in which the table is to be expanded. In this embodiment, for example, after an original 3×3 table is created using the four slit holes and the rotation direction positioning means described above, in order to expand a 3×3 table adjacent to the original 3×3 table, the position of the template body 10 needs to be relocated to a new position that is shifted by three unit grid squares in the direction in which the table is to be expanded. The plane orthogonal direction positioning means according to this embodiment is used to position the template body 10 at such a new position.

[0063] The plane-orthogonal direction positioning means includes a first V-shaped groove provided in the outer peripheral region at a position away from one of N+1 points distributed at equal intervals along the entire length of one outer grid line constituting one side of the periphery of the square central region, in a direction perpendicular to the one outer grid line, toward the outer periphery of the template body by a distance equivalent to one unit square grid.

[0064] In the case of this embodiment, for example, it can be realized by combining the following configurations. Example 1: The plane orthogonal direction positioning means is composed of any one of V-shaped grooves 21, 22, 23, 41, 42, 43, and 44 provided in the template body 10, and at least one of four slit holes that can capture a portion of a created table or a table being created (for example, a frame line intersection or frame line vertex on a frame line one line inward from the outer frame line on the side where the table is to be expanded) when the template body 10 is appropriately repositioned to a predetermined position by a predetermined procedure described below. Preferably, any one of the slit holes captures, for example, a portion of the table within a hole area near the hole end of the slit hole (which may also be simply expressed as "at the hole end of the slit hole" in this specification).

[0065] Example 2: Another plane perpendicular direction positioning means is composed of any one of the V-shaped grooves 21, 22, 23, 41, 42, 43, and 44 provided in the template body 10, and any one of the slit holes 11 to 14 that can capture a mark created by placing the pen tip N of a writing instrument against any one of the V-shaped grooves used when creating the table (preferably, the V-shaped groove that will be located in the direction in which the table is to be expanded when the template body 10 is repositioned to expand the table) when the template body 10 is properly repositioned to a predetermined position by a predetermined procedure described below.

[0066] When there is only one V-shaped groove, the "slit hole capable of capturing the mark" refers to a slit hole (e.g., slit hole 14 for V-shaped groove 21) that exists at a position corresponding to the position of the V-shaped groove, with the midpoint of the outer grid line closest to the V-shaped groove as the center of symmetry. However, when there are two or more V-shaped grooves, capturing the mark is not limited to such symmetrical slit holes. For example, if marks P1 and P4 are created using V-shaped grooves 21 and 24, respectively, it can be considered that V-shaped groove 21 captures mark P1 and V-shaped groove 24 captures mark P4. Furthermore, for example, slit hole 41 can capture mark P1 created by V-shaped groove 41 (which is point-symmetric to V-shaped groove 21 with respect to origin O as the center of symmetry).

[0067] Example 3: Referring to FIG. 1, yet another orthogonal plane direction positioning means may be configured with one of the four outer slit holes and at least one V-shaped groove located on a grid line extending parallel to and closest to the slit hole. Specifically, the positioning means may be configured with one of the V-shaped grooves 51, 52, 53, or 54 and one slit hole 11 that can capture the entire outer border of the extended side of the created table when the template body 10 is properly repositioned in a predetermined position according to a predetermined procedure described below. Alternatively, the positioning means may be configured with one of the V-shaped grooves 31, 32, 33, or 34 and a slit hole 14 that can capture the entire outer border of the extended side of the created table when the template body 10 is properly repositioned in a predetermined position according to a predetermined procedure described below. This is described below in FIG. 7A(A).

[0068] Example 4: Yet another alternative positioning means in the direction perpendicular to the plane is constituted by a first V-shaped groove and a second V-shaped groove (for example, if one outer grid line is line PQ, any two of V-shaped grooves 21, 22, 23, and 24) provided at positions on the outer periphery of the template body that are separated from two of four points positioned at equal intervals over the entire length of one outer grid line (line PQ, line QR, line RS, or line SP) in a direction perpendicular to the outer grid line by a distance equivalent to one unit grid square. The above-mentioned yet another alternative positioning means in the direction perpendicular to the plane functions when the first V-shaped groove and second V-shaped groove are appropriately repositioned to predetermined positions by a predetermined procedure described below.

[0069] The above-mentioned "predetermined procedure" will become clear in the following description of how to use the template 1, which will be given with reference to Figures 5A to 7D. Figures 5A to 7D (A) show the template body 10 placed on a piece of paper (not shown), and the lines and marks created using this template body 10. Figures 5A to 7D (B) show only the lines and marks created with the template body 10 removed.

[0070] Next, with reference to FIGS. 5A to 5C, a method for using template 1 to create the first 3×3 table will be described.

[0071] In step S1, as shown in FIG. 5A(A), for example, the template body 10 is placed in a first position and a first orientation on a piece of paper (not shown), and while keeping the template body 10 stationary, the pen tip N of a writing implement (e.g., a ballpoint pen, a mechanical pencil, a pencil, etc.) is inserted sequentially into the four slit holes 11, 12, 13, and 14 and moved over its entire length to draw four parallel lines L1, L2, L3, and L4 on the paper surface. It is also possible to place the pen tip N of a writing implement on two V-shaped grooves (for example, V-shaped grooves 41 and 44) ​​to create marks P1 and P4, respectively.

[0072] Note that symbols P11 and P14 indicate the ends of line L1. P21 and P24 indicate the ends of line L2. P31 and P34 indicate the ends of line L3. P41 and P44 indicate the ends of line L4. Note that the order in which the individual tasks within step 1 are performed is free.

[0073] In step S2, as shown in Fig. 5B, the template body 10 is rotationally positioned in the second direction at the first position using a rotational positioning means. If the marks P1 and P4 have been created in step 1, this positioning can be performed simply and quickly by aligning the V-shaped grooves 31 and 34 with the marks P1 and P4.

[0074] If only one of the marks P1 and P4 is created (e.g., when the V-shaped groove 31 is simply aligned with the mark P1), one of the two points required for rotational positioning can be identified using the mark, and the other point can be identified by capturing the leading ends of the lines P11 and P41 within the hole region near the hole ends 11a and / or 11c of the slit hole 11, which are farthest from the mark P1. In this case, by first aligning the V-shaped groove 31 with the mark P1, it is easy to capture the leading ends of the lines P11 of the line L1 and P41 of the line L4 within the hole region near the hole ends 11a and / or 11c, thereby enabling rapid rotational positioning. Furthermore, P1 and 11a are separated by four unit grids, and P1 and 11c are separated by even more, which allows for more accurate rotational positioning.

[0075] Furthermore, even if marks P1 and P4 are not used, for example, if the template body 10 is made of a transparent or translucent material and has the above-mentioned auxiliary lines on the template body 10, these auxiliary lines can be used to perform rotational positioning.

[0076] Various techniques for aligning the template body 10 in the second orientation at the first position have been described above, but the present invention is not limited to these. As long as the first alignment can be achieved, the alignment may be performed using a procedure different from that described above. Furthermore, the first alignment may be performed by combining two or more of the techniques described above.

[0077] In step S3, as shown in Figure 5C, the pen tip N of the writing implement is again inserted sequentially into the four slit holes 11, 12, 13, and 14 and moved over its entire length to draw four new parallel lines L5, L6, L7, and L8 on the paper. This allows the creation of a 3x3 table as shown in Figure 5C(B).

[0078] Next, with reference to FIGS. 6A-6D, we will explain how to use Template 1 to expand the 3×3 table completed in FIG. 5C.

[0079] First, in step S4, as shown in FIG. 6A, the template body 10 is shifted from the first position (see FIGS. 5A-5C) in the direction in which the front is to be expanded. Then, the position and orientation of the template body 10 are adjusted so that, for example, the valleys 21b of V-shaped groove 21, 22b of V-shaped groove 22, 23b of V-shaped groove 23, and 24b of V-shaped groove 24 coincide with the corresponding frame line intersections P12, P23, P33, and P43 on the frame line L7, which is one line inward from the outer frame line L8 on the front expansion side. This completes the simplest and quickest alignment. Furthermore, the slit holes 11 and 14, among the four slit holes 11-14, capture the marks P4 and P1, respectively. This allows the template body 10 to more accurately position the second position and first orientation for extending a table adjacent to an existing 3x3 table (or for extending a 3x3 table adjacent to an existing 3x3 table).

[0080] Although two marks and four V-shaped grooves are used here, it is also possible to position the template body 10 at the second position using a different number of V-shaped grooves and a different number of marks. For example, even if only one mark is created, the template body 10 can be easily positioned at the second position by capturing the mark with one slit hole corresponding to the mark.

[0081] Furthermore, even if marks are not used, the template body 10 can be easily positioned in the second position by capturing a characteristic part of an existing 3x3 table, for example, a corner of the table (both or one of P14 and P44), instead of the marks, within the hole area near the hole end 11a of the corresponding slit hole 11 and / or the hole end 14a of the slit hole 14.

[0082] Furthermore, even if there is only one V-shaped groove and this V-shaped groove is used to create a mark (for example, if there is only one V-shaped groove, V-shaped groove 21, and the only mark P1 is created using V-shaped groove 21), the template body 10 can be easily positioned at the second position by having the corresponding slit hole (slit hole 14 in the previous example) capture the mark. Furthermore, even without creating mark P1, the template body 10 can be positioned at the second position by having the hole edge of one of the slit holes capture the above-mentioned characteristic portion of an existing 3 × 3 table. In other cases as well, the template body 10 can be positioned at the second position using a similar concept.

[0083] In step S5, as shown in FIG. 6B, four slit holes 11, 12, 13, and 14 are used to draw extensions of four parallel lines L1, L2, L3, and L4 (sections P14 to P17, P24 to P27, etc.).

[0084] In step S6, the template body 10 is positioned in a second position and a second orientation, as shown in Fig. 6C. This positioning can be achieved using any of the techniques described in step 2 with reference to Fig. 5B, either singly or in combination. For example, in this embodiment, by aligning at least two of the V-shaped grooves 31 to 34, for example, the two V-shaped grooves 31 and 34, with specific frame line intersections (P13 and P43 in the above example) on the frame line one border inward from the frame line on the side where the existing 3x3 table is to be expanded, the template body 10 can be easily aligned in a second orientation at a second position. Furthermore, for example, if at least one of the marks P1 and P4 has been created, alignment can also be easily achieved by capturing the created marks P1 and / or P4 with the corresponding slit holes 13, either alone or in combination with other techniques (for example, a technique using V-shaped grooves 31 and / or 34).Also, as shown in Fig. 6C(A), alignment can also be achieved by capturing the outer border line L8 of an existing table with the entire slit hole 14, either alone or in combination with other techniques. Furthermore, by capturing the respective tip portions P17 and P47 of the frame lines L1 and L4 extended in step S5 within the hole area near both ends 11a and / or 11c of the slit hole 11 in the template body 10, and combining this with other techniques (e.g., alignment means using V-shaped grooves 21 and / or 24), the template body 10 can be aligned in the second orientation at the second position with greater accuracy.

[0085] In step S7, as shown in Fig. 6D, four parallel lines L8, L9, L10, and L11 are again drawn using four slit holes 11, 12, 13, and 14. This allows a 3x6 table to be created by connecting the new 3x3 table adjacent to the original 3x3 table, as shown in Fig. 6D(B).

[0086] In this embodiment, the explanation ends with the creation of a 3x6 table, but template 1 of the present invention is not limited to this. Various tables can be created using the procedure described above, such as 6x6, 6x9, etc.

[0087] Moreover, instead of steps S4 to S7 shown in FIGS. 6A to 6D, the procedures shown in FIGS. 7A to 7D, which will be described next, may be used.

[0088] First, in step S4′, as shown in FIG. 7A, the template body 10 is shifted from the first position (see FIGS. 5A to 5C) in the direction in which the table is to be expanded. Then, the template body 10 is positioned and oriented so that at least two of the valleys 51b of V-shaped groove 51, 52b of V-shaped groove 52, 53b of V-shaped groove 53, and 54b of V-shaped groove 54 correspond to at least two corresponding points among the frame line intersections P13, P23, P33, and P43 on the frame line L7, which is one step inward from the outer frame line L8 on the expanded side of the table. This completes the simplest and quickest alignment. Furthermore, the slit hole 12 can capture the marks P4 and P1 within the hole regions near its two hole ends 12a and 12c. This allows the template body 10 to more accurately position the second position and first orientation for extending a table adjacent to an existing 3x3 table (or for extending a 3x3 table adjacent to an existing 3x3 table).

[0089] 7A, since the slit hole 11 can capture the entire straight line L8 of the existing 3x3 table, it is possible to position the template body 10 at the second position and in the first orientation by using only this or by combining this with other techniques (for example, a technique using V-shaped grooves 51, 54). In any case, the operator has multiple options for positioning the template body 10 at the second position and can select the technique that he or she thinks will provide the easiest positioning, making it even easier to use.

[0090] In step S5', three parallel lines L9, L10, and L11 are drawn using three slit holes 12, 13, and 14, as shown in FIG. 7B.

[0091] In step S6', the template body 10 is positioned in a second position and a second orientation, as shown in Figure 7C. This positioning can be achieved using any of the techniques described above in step 2 with reference to Figure 5B, either singly or in combination. For example, in the present embodiment, the template body 10 can be easily aligned in a second orientation at a second position by aligning at least two of the V-shaped grooves 21, 22, 23 and 24, for example, two locations of the V-shaped grooves 21 and 24, with specific border line intersections (P13 and P43 in the above example) on the border line one border inward from the border line on the side where the existing 3x3 table is to be expanded. Alternatively, for example, if at least one of the marks P1 and P4 has been created, the marks P1 and P4 can be captured by the slit holes 11 and 14, and the template body 10 can be easily aligned in the second orientation at the second position with greater precision, either alone or in combination with other techniques (e.g., a technique using V-shaped grooves 21 and / or 24, and a technique using auxiliary lines). Furthermore, by capturing the respective tip portions P17 and P47 of the frame lines L1 and L4 extended in step S5' within the hole area near both ends 11a and / or 11c of the slit hole 11 in the template body 10, and combining this with other techniques (e.g., alignment means using V-shaped grooves 21 and / or 24), the template body 10 can be aligned in the second orientation at the second position with greater accuracy.

[0092] In step S7', as shown in Fig. 7D, extensions of four parallel lines L1, L2, L3, and L4 are again drawn using four slit holes 11, 12, 13, and 14. This allows a 3x6 table to be created by connecting a new 3x3 table to the side adjacent to the existing 3x3 table, as shown in Fig. 7D(B). As mentioned above, it is also possible to continue expanding the table and create tables of 6x6, 6x9, etc.

[0093] In this embodiment, an example has been shown in which 16 V-shaped grooves are provided on the outer periphery of the template body 10. In the example using these 16 V-shaped grooves, at least two V-shaped grooves are provided on each of the four sides of the square grid G. This configuration has the advantage of making it easy to expand an existing 3 × 3 table in any direction. For example, even if the V-shaped grooves are V-shaped grooves 21 and 24 and V-shaped grooves 31 and 34, it is possible to expand an existing 3 × 3 table to create a 3 × 6 table. However, when expanding a table in a direction on the template body 10 where no V-shaped grooves exist, it may be necessary to rotate the template body 10 as needed to use the limited number of V-shaped grooves. In contrast, when at least two V-shaped grooves are provided on each of the four sides of the square grid G, including the example using 16 V-shaped grooves, such inconvenience does not occur.

[0094] Meanwhile, the number and layout of the V-shaped grooves provided on the template body 10 are not limited to those shown in Fig. 1. Other layouts of the V-shaped grooves are shown in Fig. 8A and Fig. 8B. Those skilled in the art should be able to easily imagine the actual positioning procedure with reference to the above description and Figs. 6 to 8.

[0095] For example, in the template 1A shown in Fig. 8A(A), the template body 10A has four equally spaced parallel slit holes 11-14 and one V-shaped groove 21. In the template 1A' shown in Fig. 8A(A'), the template body 10A' has four equally spaced parallel slit holes 11-14 and one V-shaped groove 31. The template bodies 10A and 10A' are transparent or semi-transparent and have auxiliary lines along a square grid G ​​as rotational direction positioning means. In both cases (A) and (A'), the rotational direction positioning procedure can be performed by, for example, first drawing four parallel lines using the slits 11 to 14 and aligning the auxiliary lines with these four parallel lines. Then, another four parallel lines are drawn using the slits 11 to 14 to complete the table. Furthermore, the second alignment procedure is In the case of (A), for example, first, the V-shaped groove 21 can be aligned with a specific frame line intersection of the table (one line inward from the outer frame line of the expanded side), and then, in that state, some characteristic parts of the table (for example, the frame line intersection and the frame line vertex) can be captured by at least one hole edge of the slit holes 11 to 14 (more specifically, by a hole area near the hole edge (the same applies hereinafter in this specification)). Alternatively, first, a mark can be created using the V-shaped groove 21 at some point during the creation of the initial table (for example, before or after rearrangement for rotational positioning (the same applies hereinafter in this specification)), and then, the V-shaped groove 21 can be aligned with a specific frame line intersection of the table, and then, in that state, the created mark can be captured by the slit hole 14. On the other hand, in the case of (A'), the second alignment procedure can be performed, for example, by first aligning the V-shaped groove 31 with a specific intersection of the border lines of the table, and then capturing a characteristic part of the table (here, the outer border line of the table on the side where the table is to be expanded) with the entire slit hole 14. Alternatively, for example, the second alignment procedure can be performed by creating a mark using the V-shaped groove 31 at some point during the creation of the initial table, and then aligning the V-shaped groove 31 with a specific intersection of the border lines of the table, and then capturing the created mark with the edge of the slit hole 13.

[0096] For example, in the template 1B shown in Fig. 8A(B), the template body 10B has four equally spaced parallel slit holes 11 to 14 and V-shaped grooves 21 and 24. In the template 1B' shown in Fig. 8A(B'), the template body 10B' has four equally spaced parallel slit holes 11 to 14 and V-shaped grooves 31 and 34. The template bodies 10B and 10B' are transparent or semi-transparent and have auxiliary lines along a square grid G ​​as rotational direction positioning means. In both cases (B) and (B'), the rotational direction positioning procedure can be performed by, for example, first drawing four parallel lines using the slits 11 to 14 and aligning the auxiliary lines with these four parallel lines. Then, another four parallel lines are drawn using the slits 11 to 14 to complete the table. Furthermore, the second alignment procedure is In the case of (B), for example, this can be done by aligning the V-shaped grooves 21 and 24 with a specific frame line intersection point of the table (one line inside the outer frame line of the expanded side) and, in that state, capturing some characteristic parts of the table (for example, a frame line intersection point and a frame line vertex) with the edge of at least one of the slit holes 11 to 14. Alternatively, this can be done by first creating two markers using the V-shaped grooves 21 and 24 at some point during the creation of the initial table, and then aligning the V-shaped groove 21 with a specific frame line intersection point of the table and, in that state, capturing the two created markers with the slit holes 11 and 14. On the other hand, in the case of (B'), the plane perpendicular direction positioning means can be implemented by, for example, aligning the V-shaped grooves 31 and 34 with specific intersections of the frame lines of the table, and then capturing a characteristic part of the table (here, the outer frame line of the table on the side to be expanded) with the entire slit hole 14. Alternatively, it can be implemented by first creating two marks using the V-shaped grooves 31 and 34 at any point during the creation of the initial table, and then aligning the V-shaped grooves 31 and 34 with specific intersections of the frame lines of the table, and then capturing the two created marks with both ends of the slit hole 13.

[0097] Furthermore, for example, in the template 1C shown in Fig. 8A(C), the template body 10C may have four equally spaced parallel slit holes 11-14 and V-shaped grooves 21 and 31 provided at positions that are angularly different from each other by 90 degrees around the center point of the square grid. Also, in the template 1C' shown in Fig. 8B(C'), the template body 10C' may have four equally spaced parallel slit holes 11-14 and V-shaped grooves 31 and 34 provided at positions that are angularly different from each other by 90 degrees around the center point of the square grid. Note that the template bodies 10C and 10C' may be opaque. In the case of (C), the rotational positioning procedure can be performed, for example, by first drawing four parallel lines using the slit holes 11 to 14 and creating marks using the V-shaped groove 31 (or V-shaped groove 21), then rearranging the template body 10C to align the V-shaped groove 21 (or V-shaped groove 31) with the marks, and in this state, using the edge of any of the slit holes 11 and / or 14 to capture the ends of the parallel lines.In addition, in the case of (C'), the rotational positioning procedure can be performed, for example, by first drawing four parallel lines using the slit holes 11 to 14 and creating marks using the V-shaped groove 31 (or V-shaped groove 41), then rearranging the template body 10C' to align the V-shaped groove 41 (or V-shaped groove 31) with the marks, and in this state, using the edge of any of the slit holes 11 and / or 14 to capture the ends of the parallel lines. After that, draw another four parallel lines using the slit holes 11 to 14 to complete the table. Furthermore, the positioning procedure in the direction perpendicular to the plane can be performed, for example, by aligning V-shaped groove 21 (in the case of (C)) or V-shaped groove 41 (in the case of (C')) with a specific frame line intersection point of the table (one line inside the outer frame line of the extended side) and, in that state, capturing a characteristic part of the table (for example, a frame line vertex) with the hole edge of slit hole 11 or 14. Alternatively, it can be performed by creating a single mark using either V-shaped groove at any point during the creation of the initial table, aligning V-shaped groove 21 (in the case of (C)) or V-shaped groove 41 (in the case of (C')) with a specific frame line intersection point of the table (one line inside the outer frame line of the extended side), and, in that state, capturing the single mark that has already been created with slit holes 11 and 14. Alternatively, the positioning procedure in the perpendicular plane direction can be performed, for example, by aligning the V-shaped groove 31 (in both cases (C) and (C')) with a specific intersection of the frame lines of the table, and in that state, capturing a characteristic part of the table (here, the outer frame line of the table on the side where the table is to be expanded) with the entire slit hole 14. Alternatively, for example, the procedure can be performed by creating a single mark using one of the V-shaped grooves at any point during the creation of the initial table, and then aligning the V-shaped groove 31 (in the cases (C) and (C')) with a specific intersection of the frame lines of the table, and in that state capturing the single mark that has already been created with the edge of the slit hole 13.

[0098] For example, in a template 1D shown in Fig. 8B(D), a template body 10D includes four equally spaced parallel slit holes 11-14, V-shaped grooves 21 and 31 disposed at positions that are angularly offset by 90 degrees from each other around the center of the square grid, and V-shaped grooves 24 and 34 disposed at positions that are angularly offset by 90 degrees from each other around the center of the square grid. Also, in a template 1D' shown in Fig. 8B(D'), a template body 10D' includes four equally spaced parallel slit holes 11-14, V-shaped grooves 31 and 41 disposed at positions that are angularly offset by 90 degrees from each other around the center of the square grid, and V-shaped grooves 34 and 44 disposed at positions that are angularly offset by 90 degrees from each other around the center of the square grid. In the case of (D), the rotational positioning procedure can be performed, for example, by first creating two marks using the V-shaped grooves 31 and 34 (or the V-shaped grooves 21 and 24), and then rearranging the template body 10C to align the V-shaped grooves 21 and 24 (or the V-shaped grooves 31 and 34 if the marks are created using the V-shaped grooves 21 and 24). In the case of (D'), the rotational positioning procedure can be performed, for example, by first creating two marks using the V-shaped grooves 31 and 34 (or the V-shaped grooves 41 and 44), and then rearranging the template body 10C to align the V-shaped grooves 41 and 44 (or the V-shaped grooves 31 and 34) with the two marks. Furthermore, in both the cases of (D) and (D'), more accurate positioning can be achieved by adding that the ends of the slit holes 11 and / or 14 capture the ends of the parallel lines. After that, draw another four parallel lines using the slit holes 11 to 14 to complete the table. The orthogonal plane direction positioning procedure can be performed, for example, by aligning V-shaped grooves 21 and 24 (in the case of (D)) or V-shaped grooves 41 and 44 (in the case of (D')) with a specific frame line intersection point of the table (one line inside the outer frame line of the extended side) and, in that state, capturing a characteristic portion of the table (for example, a frame line vertex) with the hole edge of slit hole 11 or 14. Alternatively, it can be performed by creating one or two adjacent marks using either of the V-shaped grooves at any point during the creation of the initial table, aligning V-shaped grooves 21 and 24 (in the case of (D)) or V-shaped grooves 41 and 44 (in the case of (D')) with a specific frame line intersection point of the table (one line inside the outer frame line of the extended side), and, in that state, capturing the created one or two adjacent marks with slit holes 11 and 14. Alternatively, the positioning procedure in the perpendicular plane direction can be performed, for example, by aligning the V-shaped grooves 31 and 34 (in the cases of (D) and (D')) with specific intersections of the frame lines of the table, and then capturing a characteristic part of the table (here, the outer frame line of the table on the side where the table is to be expanded) with the entire slit hole 14. Alternatively, for example, the procedure can be performed by creating one or two adjacent marks using any of the V-shaped grooves at any point during the creation of the initial table, and then aligning the V-shaped grooves 31 and 34 (in the cases of (D) and (D')) with specific intersections of the frame lines of the table, and then capturing the created one or two adjacent marks with the hole edges of the slit hole 13.

[0099] 8B(E), the template body 10E includes four equally spaced parallel slit holes 11-14, V-shaped grooves 21 and 41 positioned at an angle of 180 degrees from each other with the center point of the grid as the rotation center, and V-shaped grooves 24 and 44 also positioned at an angle of 180 degrees from each other. The template bodies 10B and 10B' are transparent or semi-transparent and include auxiliary lines along the grid G ​​as rotational positioning means. In both cases (E) and (E'), the rotational direction positioning procedure can be performed by, for example, first drawing four parallel lines using the slits 11 to 14 and aligning the auxiliary lines with these four parallel lines. Then, another four parallel lines are drawn using the slits 11 to 14 to complete the table. Furthermore, in the case of (E), the second alignment procedure can be performed, for example, by aligning V-shaped grooves 21 and 24 or 41 and 44 with a specific border intersection of the table (one intersection inward from the outer border of the expanded side) and, in that state, capturing a characteristic portion of the table (for example, a border vertex) with the hole edge of slit hole 11 or 14. Alternatively, for example, the second alignment procedure can be performed by creating one or two marks using one or both of V-shaped grooves 21 and 24 or one or both of V-shaped grooves 41 and 44 belonging to any V-shaped groove group at any point during the creation of the initial table, and then aligning V-shaped grooves 21 and 24 or 41 and 44 with a specific border intersection of the table and, in that state, capturing the created one or two marks with the hole edge of slit hole 11 or 14. On the other hand, in the case of (E'), for example, V-shaped grooves 31 and 34 or 51 and 54 can be aligned with a specific border intersection of the table (one intersection inward from the outer border of the expanded side), and in that state, a characteristic part of the table (here, the outer border of the table on the expanded side where the table is to be expanded) can be captured by the entire slit hole 14. Alternatively, for example, at some point during the creation of the initial table, one or two marks can be created using V-shaped grooves 31 and 34 or 51 and 54 belonging to any V-shaped groove group, and then V-shaped grooves 31 and 34 or 51 and 54 can be aligned with a specific border intersection of the table, and in that state, the one or two created marks can be captured by the edge of slit hole 13.

[0100] Furthermore, for example, in the template 1F shown in Fig. 8B(F), the template body 10F includes four equally spaced parallel slit holes 11-14, V-shaped grooves 21, 31, 41, and 51 provided at intervals of 90 degrees of rotation around the center point of the square grid G, and V-shaped grooves 24, 34, 44, and 54 also provided at intervals of 90 degrees of rotation. The template 1F in Fig. 8B(F) includes all of the components of the templates 1C, 1C', 1D, and 1D' shown in Figs. 8A(C), 8A(C'), 8B(D), and 8B(D'), and therefore the basic procedures for positioning in the rotational direction and the direction orthogonal to the plane are the same, and therefore descriptions thereof will be omitted here.

[0101] [Effects of this embodiment] (1) The template according to this embodiment is configured so that the template body has four slit holes and a rotational direction positioning means. Using these, the template according to this embodiment can quickly create a table consisting of multiple squares arranged vertically and horizontally, with at least one side of the table being sized according to the length of the four slit holes. In addition, the template according to this embodiment also includes a positioning means for orthogonal to the plane, which includes a V-shaped groove located at a distance from the slit hole equal to the length of the slit hole. Therefore, if necessary, the user can quickly expand the table to the side adjacent to the created table in the direction in which the user wants to expand the table by using the positioning means for orthogonal to the plane and the positioning means for rotation. Furthermore, by repeatedly using the positioning means for orthogonal to the plane and the positioning means for rotation, the table can be repeatedly expanded in the desired direction.

[0102] (2) Furthermore, the template body is configured to be positioned using a V-shaped groove when rearranging the template body to expand the table. This simplifies the task of aligning the characteristic parts of the template body with the characteristic parts of the target table, and allows for quick positioning, compared to positioning the template body when rearranging it without using such a V-shaped groove (for example, compared to capturing the characteristic parts of the table using only slit holes).

[0103] (3) Furthermore, during table creation, one or more marks can be created on the paper using a V-shaped groove, and these marks can be used to position the template body in a direction perpendicular to the plane, making alignment easier. For example, one of the two points required to position the template body in a direction perpendicular to the plane on the paper can be identified using a V-shaped groove, and the other point can be identified by capturing a mark near the edge of a slit hole, etc., and if the distance between the two points can be made wide, accurate positioning can be achieved.

[0104] (4) Furthermore, when there is at least one V-shaped groove pair with an angle difference of 90 degrees relative to the center point of the square central region, it becomes possible to adopt a rotational direction positioning means that uses a mark for one of the two points required for rotational direction positioning. This makes rotational direction positioning simpler and faster than performing rotational direction positioning using only the slit hole and the characteristic part of the surface without using a V-shaped groove mark. Furthermore, since the distance between the V-shaped groove (valley) and the center point can be made wider than the distance between the hole edge of the slit hole and the center point, it is possible to perform positioning with high precision.

[0105] (5) Furthermore, when there are two or more V-shaped groove pairs with an angle difference of 90 degrees relative to the center point of the central region, it becomes possible to configure a rotational direction positioning means using only two or more V-shaped groove pairs, which further speeds up the rotational direction positioning work and improves the positioning accuracy.

[0106] (6) Furthermore, the shape of the V-shaped groove itself is designed to easily accept or introduce the pen tip of a writing instrument, which also speeds up the work of rotational alignment and alignment in the direction perpendicular to the plane, thereby speeding up the creation and expansion of tables.

[0107] (7) When there is at least one V-shaped groove group on each of the four sides of the template body, the user can create the first table on paper using a V-shaped groove that is easy for the user to use, without having to worry about the orientation of the template, which speeds up table creation and improves convenience. Furthermore, when extending a table to an adjacent side, the user can create a marker using one or more V-shaped grooves located in the direction of the desired table extension, without having to worry about the position of the V-shaped groove on the template, and can use these markers to quickly expand the table, improving convenience. More preferably, when there are at least two V-shaped groove groups on each of the four sides of the template body, this further speeds up creation and improves convenience.

[0108] (8) Furthermore, when using two or more V-shaped groove pairs, the accuracy of rotational positioning can be further improved by creating two markers as far apart as possible (for example, creating two markers using V-shaped grooves at opposite positions relative to the center point of the square central area).

[0109] (9) For each of the two positioning means, multiple configurations are available that the template user can select and use at the time of use. Depending on the situation, the user can use a configuration that is easy to use, a configuration that prioritizes speed, or a configuration that allows for highly accurate positioning, which also leads to improved convenience.

[0110] (10) Since a table larger than the template can be created without increasing the dimensions of the template, a table with cells large enough to hold the desired number of characters can be created without compromising the portability of the template. Moreover, this table can be expanded from a 3x3 table to various tables such as 3x6, 3x9, 6x6, 6x9, and 9x9.

[0111] (11) When creating a table, it is possible to omit drawing some of the lines, which makes it possible to make the smallest square that makes up the table a 1 x 3 square. Similarly, when creating a table, it is possible to create a 2 x 3 table by not drawing some of the outer border lines of the table.

[0112] The above effects have been described as effects of the first embodiment, but they also apply to the second embodiment, the third embodiment, and other embodiments described below.
