[0014] The present invention will be described below with reference to the figures. In this embodiment, the ruler (130) of the present invention is typically used to cut styrene board (S), which is used in the production of architectural models, to a predetermined width. However, the use of the ruler (130) of the present invention is not limited to the production of architectural models, and it may be used for other purposes. Furthermore, the ruler (130) of the present invention is not limited to cutting board materials such as styrene board (S), but may also be used to cut sheet materials such as leather, paper, film, felt, or carpet.

[0015] As shown in Figures 1, 12, 13, 14, 15, 16, and 17, the ruler (130) of the present invention is obtained by combining one or more of several types of notched rulers (140, 150, 160, 170). In the embodiment shown in the figures, the ruler (130) is placed on the styrene board (S) to be cut and used in conjunction with the stopper (110).

[0016] The marking rulers consist of a group of millimeter marking rulers (140), a group of comma marking rulers (150), a group of centimeter marking rulers (160), and a 10-centimeter marking ruler (170).

[0017] As shown in Figure 2, the millimeter-marked ruler group (140) is a set of nine marking rulers (141, 142, 143, 144, 145, 146, 147, 148, 149) with widths in 1 mm increments. Specifically, they are formed to have widths of 11 mm (141W), 12 mm (142W), 13 mm (143W), 14 mm (144W), 15 mm (145W), 16 mm (146W), 17 mm (147W), 18 mm (147W), and 19 mm (149W).

[0018] Each of the millimeter-marked rulers (141, 142, 143, 144, 145, 146, 147, 148, 149) has a different width, but the other components are the same. Therefore, the following explanation will focus on the 11mm-marked ruler (141). The 11mm-marked ruler (141) is plate-shaped, with a length (141L) of 150mm, a width (141W) of 11mm, and a thickness of 2mm. Since the 11mm-marked ruler (141) is linearly extended with a uniform width, a pair of parallel long sides (141a, 141b) are provided. The 11mm-marked ruler (141) has width dimension indicators (141D) in four locations: two at each end, on the front and back surfaces, where the width dimension is displayed numerically.

[0019] As shown in Figure 3, the comma-marked ruler group (150) is a set of nine marking rulers (151, 152, 153, 154, 155, 156, 157, 158, 159) with widths in 0.1 mm increments. Specifically, they are formed to have widths of 10.1 mm (151W), 10.2 mm (152W), 10.3 mm (153W), 10.4 mm (154W), 10.5 mm (155W), 10.6 mm (156W), 10.7 mm (157W), 10.8 mm (158W), and 10.9 mm (159W).

[0020] Each of the comma-marked rulers (151, 152, 153, 154, 155, 156, 157, 158, 159) has a different width, but the other components are the same. Therefore, the following explanation will focus on the 10.1 mm wide ruler (151). The 10.1 mm ruler (151) is plate-shaped, with a length (151L) of 150 mm, a width (151W) of 10.1 mm, and a thickness of 2 mm. Since the 10.1 mm ruler (151) is linearly extended with a uniform width, a pair of parallel long sides (151a, 151b) are provided. The 10.1mm increment ruler (151) has width dimension indicators (151D) in four locations: two at each end, on the front and back surfaces, where the width dimension is displayed numerically.

[0021] As shown in Figure 4, the centimeter-marked ruler group (160) is a set of five marking rulers (161, 162, 163, 164, 165) with widths in 10 mm increments. Specifically, they are formed to have widths of 10 mm (161W), 20 mm (162W), 30 mm (163W), 40 mm (164W), and 50 mm (165W).

[0022] Each of the centimeter-marked rulers (161, 162, 163, 164, 165) has a different width, but the other components are the same. Therefore, the following explanation will focus on the 10mm wide ruler (161). The 10mm wide ruler (161) is plate-shaped, with a length (161L) of 150mm, a width (161W) of 10mm, and a thickness of 2mm. Since the 10mm wide ruler (161) is extended linearly with a uniform width, a pair of parallel long sides (161a, 161b) are provided. The 10mm wide ruler (161) has width dimension indicators (161D) in four locations: two at each end, on the front and back surfaces, where the width dimension is displayed numerically.

[0023] As shown in Figure 5, the 10-centimeter marking ruler (170) is a set of marking rulers (140, 150, 160, 170) formed so that the width dimension (170W) is 100 mm. The 10-centimeter marking ruler (170) is plate-shaped, with a length (170L) of 150 mm, a width (170W) of 100 mm, and a thickness of 2 mm. Since the 10-centimeter marking ruler (170) is extended linearly with a uniform width dimension, a pair of long sides (170a, 170b) are provided parallel to each other. The 10-centimeter marking ruler (170) has width dimension indicators (170D) in four locations, two at each end of the front and back surfaces, where the width dimension is displayed numerically.

[0024] First, with reference to Figures 10 and 11, we will explain how to obtain a ruler (130) of the desired dimensions.

By bringing the long sides of these notched rulers (140, 150, 160, 170) into contact, a ruler (130) with the desired width dimension can be obtained. In this case, if the desired dimension can be obtained with a single notched ruler (140, 150, 160, 170), then only one notched ruler (140, 150, 160, 170) may be selected.

[0025] For example, if the desired width dimensions of the ruler (130) are 13mm, 26mm, 81mm, and 177mm, and further, if the desired width dimensions of the ruler (130) include a tenth, such as 22.8mm, 58.4mm, 77.7mm, and 183.8mm, the combinations of the notched rulers (140, 150, 160, 170) will be explained below based on Figures 10 and 11.

[0029] <Ruler with a width of 177mm (130)> As shown in Figure 10(d), if you want a ruler (130) with a width dimension (304) of 177 mm, select a 17 mm marked ruler (147) from the millimeter marked ruler group (140), a 10 mm marked ruler (161) and a 50 mm marked ruler (165) from the centimeter marked ruler group (160), select a 10 centimeter marked ruler (170), and bring the long sides of each marked ruler (147, 161, 165, 170) into contact with each other.

[0030] <Ruler with a width of 22.8mm (130)> As shown in Figure 11(a), if a ruler (130) with a width dimension (305) of 22.8 mm is desired, select a 10.8 mm marked ruler (158) from the comma marked ruler group (150) and a 12 mm marked ruler (142) from the millimeter marked ruler group (140), and bring the long sides of each marked ruler (158, 142) into contact with each other.

[0031] <Ruler with a width of 58.4mm (130)> As shown in Figure 11(b), if you want a ruler (130) with a width dimension (306) of 58.4 mm, select a 10.4 mm ruler (154) from the comma ruler group (150), an 18 mm ruler (148) from the millimeter ruler group (140), and a 30 mm ruler (163) from the centimeter ruler group (160), and bring the long sides of each ruler (154, 148, 163) into contact with each other.

[0032] <Ruler with a width of 77.7mm (130)> As shown in Figure 11(c), if you want a ruler (130) with a width dimension (307) of 77.7 mm, select a 10.7 mm ruler (157) from the comma ruler group (150), a 17 mm ruler (147) from the millimeter ruler group (140), and a 50 mm ruler (165) from the centimeter ruler group (160), and bring the long sides of each ruler (157, 147, 165) into contact with each other.

[0033] <Ruler with a width of 183.8mm (130)> As shown in Figure 11(d), if you want a ruler (130) with a width dimension (308) of 183.8 mm, select a 10.8 mm ruler (158) from the comma ruler group (150), a 13 mm ruler (143) from the millimeter ruler group (140), a 10 mm ruler (161) and a 50 mm ruler (165) from the centimeter ruler group (160), and then select a 10 centimeter ruler (170), and bring the long sides of each ruler (158, 143, 161, 165, 170) into contact with each other.

[0034] By aligning the long side of the ruler (130) with the desired dimensions obtained by the above procedure with the straight end formed on the side of the styrene board (S) to be cut, the opposite side of the long side of the ruler (130) can indicate a cutting position of the desired width on the styrene board (S) to be cut.

[0035] Used in the method for manufacturing a ruler of the present inventionMultiple notched rulers with different widths (140, 150, 160, 170) have parallel, predetermined dimension values ​​set on a pair of long sides. Therefore, when a user needs to determine a desired dimension, they can simply select the necessary notched ruler (140, 150, 160, 170) and then combine the selected notched rulers (140, 150, 160, 170) to obtain a ruler of the desired width (130). This allows the user to accurately obtain the desired dimension without incurring errors caused by visually reading the scale and manually adjusting the cutting position, which are necessary in cutting work based on the markings of a ruler.

[0036] The method for manufacturing the ruler (130) of the present invention at By combining marking rulers with different widths (140, 150, 160, 170), it is possible to obtain rulers (130) of any dimension in increments of one-tenth of a millimeter.

[0037] According to the manufacturing method of the ruler (130) of the present invention, it can be used as an unchanging dimensional reference in cutting work, so when performing multiple cuts of the same dimensions, the user only needs to cut based on the same ruler (130), and multiple cuts of the same dimensions can be performed accurately and efficiently without causing errors that occur due to visual reading of scales and manual adjustment of the cutting position, which are necessary in cutting work based on the scale of a ruler.

[0038] In the ruler (130) of the present invention, the group of marking rulers (140, 150, 160, 170) is a group of millimeter marking rulers (140), a group of comma marking rulers (150), a group of 1 centimeter marking rulers (160), and a 10 centimeter ruler (170). use However, depending on the implementation situation, the notched rulers (140, 150, 160, 170) may be replaced with just the millimeter notched rulers (140).

[0039] Alternatively, depending on the implementation, the notched rulers (140, 150, 160, 170) may consist only of the millimeter notched rulers (140) and the comma notched rulers (150).

[0040] Alternatively, depending on the implementation, the notched rulers (140, 150, 160, 170) could consist only of the millimeter notched rulers (140) and the centimeter notched rulers (160).

[0041] Alternatively, depending on the implementation situation, the notched rulers (140, 150, 160, 170) can be replaced with just the millimeter notched rulers (140) and the 10 cm ruler (170).

[0042] The group of marking rulers in this embodiment (140, 150, 160, 170) consists of four types: a millimeter marking ruler group (140), a comma marking ruler group (150), a centimeter marking ruler group (160), and a 10 centimeter marking ruler (170). use However, the types of notched rulers (140, 150, 160, 170) are not limited.

[0043] Furthermore, the multiple groups of marking rulers (140, 150, 160, 170) consist of 9 marking rulers in the millimeter group (140), 9 marking rulers in the comma group (150), 5 marking rulers in the centimeter group (160), and a 10 centimeter marking ruler (170). use However, the number of items belonging to each group of notched rulers (140, 150, 160, 170) is not limited.

[0044] As shown in Figures 2, 3, 4, and 5, the marking rulers (140, 150, 160, 170) of the present invention are formed with a length (141L, 151L, 161L, 171L) of 150 mm, but the length (141L, 151L, 161L, 171L) of the marking rulers (140, 150, 160, 170) may be 150 mm or more.

However, the position and number of width dimension indicators (141D, 151D, 161D, 171D) are not limited, and if they are not convenient, the width dimension indicators (141D, 151D, 161D, 171D) do not need to be provided.

[0049] This invention In the method of manufacturing a ruler, The notching rulers (140, 150, 160, 170) are made of metal, but any material suitable for cutting by guiding a blade along the ruler (130) does not need to be metal.

[0050] Next, referring to Figures 22 to 24, we will discuss the maximum and minimum dimensions obtained by combinations of marking rulers (140, 150, 160, 170). This invention describes a method for using a sheet-like material cut using a ruler obtained by the ruler manufacturing method of the present invention as a cutting ruler.

[0051] Multiple rulers of the same dimensions as the ruler (130) obtained by the manufacturing method of the present invention If necessary, A sheet-like material cut using a ruler (130) manufactured by the manufacturing method of the present invention It can be used as a notched ruler (140, 150, 160, 170) or as a spacer (232b, 232c).

[0052] Firstly, In the method for manufacturing a ruler of the present invention The method for addressing the maximum dimensional limits of the manufactured ruler (130) will be explained based on Figure 22.

[0053] In this invention, the notched rulers (140, 150, 160, 170) have a predetermined width and number, and therefore, by combining the notched rulers (140, 150, 160, 170) Manufactured Ruler (130) Width dimension There is a maximum limit to this. If you need a ruler with a width exceeding that maximum, the following options are available.

[0054] In the above case, By using a sheet-like material cut with a ruler (130) obtained by the manufacturing method of the present invention as a cutting ruler, the width dimension of the ruler obtained by the manufacturing method of the present invention can be increased.

[0055] In the example shown in Figure 22, a sheet-like material (S) is prepared, then a 100 mm notched ruler (170) is prepared, and then a ruler (130) with a width of 100 mm is manufactured by placing the 100 mm notched ruler (170) on the sheet-like material (S). Next, the sheet-like material (S) is cut using the ruler (130) to obtain a sheet-like material (S) with a width of 100 mm. Next, the 100 mm notched ruler (170) and the sheet-like material (S) cut to a width of 100 mm are placed side by side on the sheet-like material (S) with their longitudinal directions, and then the sheet-like material (S) cut to a width of 100 mm and the 100 mm notched ruler (170) are brought into contact to obtain a ruler with a width of 200 mm.

[0056] Secondly, a method for addressing the minimum dimensions obtainable by combining marking rulers (140, 150, 160, 170) will be explained based on Figures 23 and 24.

[0057] In the method for manufacturing a ruler of the present invention Among the marking rulers (140, 150, 160, 170), the one with the smallest width is the marking ruler (161) with a width of 10 mm, which belongs to the centimeter marking ruler group (160). Therefore, by combining the marking rulers (140, 150, 160, 170) Obtainable The minimum width dimension of ruler (130) is 10 mm.

[0058] Also, In the method for manufacturing a ruler of the present invention The comma-marked ruler (150) with the smallest width dimension is the 10.1 mm width ruler (151), and the millimeter-marked ruler (140) with the smallest width dimension is the 11 mm width ruler. of This is a notched ruler (141). Therefore, the dimensions include both the tenths place and the ones place, and are obtained by a combination of notched rulers (140, 150, 160, 170). Obtainable The minimum width dimension of ruler (130) is 21.1 mm.

[0059] In the method for manufacturing the ruler (130) of the present invention, both the tenths digit and the ones digit are included, and by a combination of marking rulers (140, 150, 160, 170) Obtainable Ruler (130), minimum width dimension of 21.1 mm or less When you need a ruler that can cut sheet material to a specific width, for example,If you require a cutting dimension of 17.4 mm About This will be explained based on Figure 23.

[0060] In the example shown in Figure 23, a styrene board (S) is used as the sheet material (S). As shown in Figure 23, a sheet material with a width of 10 mm is obtained by cutting the styrene board (S) using a ruler (130) obtained by placing a 10 mm wide notched ruler (161) on the styrene board (S).

[0061] Next, a ruler with a width of 17 mm (147) is selected from the millimeter-marked ruler group (140), and a ruler with a width of 10.4 mm (154) is selected from the comma-marked ruler group (150). The long sides of the two rulers (147, 154) are brought into contact with each other to manufacture a ruler (130) with a width of 27.4 mm (237).

[0062] Next, a stopper (110) is prepared. The purpose of the stopper (110) is to align the long side of the ruler (130) with the straight end formed on the side of the styrene board (S) to be cut, by bringing the long side of the ruler (130) into contact with one end face of the styrene board (S).

[0063] As shown in Figure 23, there is a width of 10 mm between the stopper (110) and the straight end formed on the side of the styrene board (S). Sheet material cut into pieces The spacer (232b) is positioned so as to abut the long side of the stopper (110) and the ruler (130). This creates a 10 mm gap (238) between the stopper (110) and the styrene board (S).

[0064] Next, a ruler (130) with a width dimension of 27.4 mm (237) is placed on the spacer (232b) and the styrene board (S), and the long side of the ruler (130) is brought into contact with the stopper (110). The opposite side of the long side of the ruler (130) points to a position 27.4 mm (239) from the contact surface of the stopper (110).

[0065] In the above state, a gap of 10 mm (238) is provided between the stopper (110) and the straight end formed on the side of the styrene board (S) by the spacer (232b). Therefore, when the long side of the ruler (130), which has a width of 27.4 mm (237), is in contact with the stopper (110), the opposite side of the long side shows a width of 17.4 mm (239) from the straight end formed on the side of the styrene board (S).

[0066] In the above state, by following the ruler (130), which has a width dimension of 27.4 mm (237), with a cutting tool and cutting, the user can obtain a cutting result (239) of 17.4 mm from the styrene board (S).

[0067] Next, as an example of a case where a cutting dimension of 10 mm or less is desired, we will explain the case where a cutting dimension of 8.2 mm is desired, based on Figure 24.

[0068] Following the procedure described above, a 20mm spacer (232c) is used to create a 20mm gap (243) between the stopper (110) and the styrene board (S) to be cut. The width dimension of the ruler (130), which is a combination of an 18mm wide marking ruler (148) and a 10.2mm wide marking ruler (152), is reduced by the 20mm gap (243). As a result, the 28.2mm wide ruler (130) shows a dimension of 8.2mm (244) relative to the styrene board (S). By following the ruler (130) with a cutting tool and cutting, the user can obtain a cut result (244) of 8.2mm from the styrene board (S).

[0069] The method for manufacturing a ruler of the present invention is used to produce Regarding the maximum and minimum dimensions of the ruler (130), as stated above, Obtained by the manufacturing method of the present invention Using a ruler (130) Cut sheet material This can be addressed by using it as a notched ruler (140, 150, 160, 170) or as a spacer (232b, 232c).

[0070] Alternatively, for minimal cuts, it is also effective to pre-cut the material to be cut using a ruler (130) of any desired size, and then cut it using a ruler (130) of the same size as the desired size.

[0071] Ruler manufactured by the ruler manufacturing method of the present invention The ruler (130) of the present invention is The dimensions that can be accommodated are There is no theoretical maximum limit, and similarly, the theoretical minimum limit is 0.1 mm.

[0072] Next, the stopper (110) will be described with reference to Figures 6 to 9. The stopper (110) is made of metal. The stopper (110) is in contact with one end face of the styrene board (S) and the long side of the ruler (130), and the user will use it. Ruler manufactured by the ruler manufacturing method of the present invention By using (130) and the stopper (110) together, the styrene board (S) can be cut to a more precise width.

[0073] As shown in Figures 6 and 7, the stopper (110) comprises a main body (111) and a slide plate (112). The main body (111) comprises a base (113) and a protrusion (114). The bottom (245) of the protrusion (114) and the bottom (246) of the slide plate (112) are treated with a non-slip finish, such as knurling.

[0074] As shown in Figure 8, the base (113) extends horizontally (126) so that the end face of the styrene board (S) can come into contact with it.

[0075] As shown in Figure 9, specifically, the base (113) is formed such that the cross section perpendicular to the horizontal direction (126) (vertical cross section) is trapezoidal, and comprises a bottom (115), a vertical wall surface (116) which serves as a second contact surface, another vertical wall surface (117), an inclined portion (118), and an upper surface (119). The bottom (115) is formed in a rectangular shape when viewed from the bottom. One vertical wall surface (116) is erected from one side of the bottom (115). Another vertical wall surface (117) is erected from the other side of the bottom (115). The other vertical wall surface (117) is set higher than the first vertical wall surface (116), and the inclined portion (118) and the upper surface (119) are provided from the upper end of the first vertical wall surface (116) toward the upper end of the other vertical wall surface (117).

[0076] At the bottom (115) of the base (113) described above, a protrusion (114) is provided on the other side. As shown in Figure 9, the protrusion (114) is a portion that protrudes vertically downward from the bottom (115) with a uniform thickness, and as shown in Figure 8, it is formed along the longitudinal direction (126) of the base (113). As shown in Figure 8, the longitudinal dimension (113L) of the base (113) and the protrusion (114) is 200 mm. As shown in Figure 9, the width dimension (115w) of the bottom (115) is 60 mm. The width dimension (114w) of the protrusion (114) is 15 mm. Therefore, the width dimension (122) of the bottom part other than the protruding part (114) is 45 mm. The height dimension (114b) of the protrusion (114) is 1.8 mm. Although the dimensions are as described above in this embodiment, the dimensions are not limited to these.

[0077] As shown in Figure 8, the slide plate (112) is a plate-like body extending in the longitudinal direction (126) of the base (113), and as shown in Figure 9, it is positioned on one side (116) of the bottom (115) of the base (113) of the main body (111). The slide plate (112) has screw holes (123) and is fixed to the main body (111) by bolts (124) inserted from the inclined portion (118) side of the main body. In this fixed state, the end face of the slide plate (112) located below one vertical wall surface (116) of the main body (111) functions as the first contact surface. As shown in Figure 8, the length dimension (112L) of the slide plate (112) is 202 mm. As shown in Figure 9, the width dimension (112w) of the slide plate (112) is 35 mm. The thickness dimension (112b) of the slide plate (112) is 1.8 mm. Although the dimensions are as described above in this embodiment, the dimensions are not limited to these.

[0078] As shown in Figure 9, the main body (111) has an elongated hole (125) through which a bolt (124) is inserted, extending from the inclined portion (118) to the bottom portion (115). The elongated hole (125) is formed to be long in the width direction (127) of the base portion (113), and the fixing position by the bolt (124) can be adjusted in the width direction. The bolt (124) inserted through the elongated hole (125) is screwed into the screw hole (123) of the slide plate (112), thereby fixing the slide plate (112) to the bottom portion (115) of the main body. In this embodiment, the slide plate (112) is fixed so that its position can be changed by 1 mm in the width direction (127) relative to the main body.

[0079] Next, referring to Figures 12 to 18, Obtained by the method for manufacturing a ruler of the present invention This section explains how to address errors caused by the blade thickness (214) of the cutting tool (K) used when cutting styrene board (S) using a ruler (130).

[0080] As shown in Figure 12(a), as an example, to align the long side of a ruler (130) consisting of a 30 mm wide notched ruler (163) with a straight end formed on the side of a 2 mm thick styrene board (S), the styrene board (S) and the ruler (130) consisting of the notched ruler (163) are brought into contact with the vertical wall surface (215) of a rectangular block (211), and the cutting is performed with a blade (K) with a blade thickness (214) of 0.4 mm, as shown in Figure 12(b).

[0081] This block (211) has a long side dimension (211a) of 200 mm, a short side dimension (211b) of 30 mm, and a vertical wall height dimension (211c) of 15 mm.

[0082] As shown in Figure 12(b), after the styrene board (S) is brought into contact with the vertical wall surface (215) of the block (211), a marking ruler (163) with a width of 30 mm is placed on the styrene board (S). By arranging these elements, a ruler with a width of 30 mm is manufactured. When a ruler (130) consisting of the notched ruler (163) is brought into contact with the same vertical wall surface (215) as the styrene board (S), and a blade (K) with a blade thickness (214) of 0.4 mm is cut along the ruler (130) consisting of the notched ruler (163), as shown in Figure 13, the tip of the blade (K) is located in the center of the blade thickness (214). Therefore, the cut styrene board (S) has a dimension (216) of 0.2 mm, which is half the blade thickness (214), added to the width dimension (30 mm) of the ruler (130) consisting of the notched ruler (163), resulting in a dimension (217) of the cut material of 30.2 mm.

[0083] As described above, there are three ways to address the added dimension due to the blade thickness (214) and obtain the desired cutting result.

[0084] The first method is to manufacture a ruler (130) with a value obtained by subtracting the dimension added by the blade thickness (214) from the desired dimension.

[0085] In the example above, if you want to cut a 30mm length with a blade (K) with a blade thickness (214) of 0.4mm, you can use a 29.8mm ruler (130) to cut, subtracting the 0.2mm dimension (216) added by the blade thickness (214). This will cancel out the added 0.2mm dimension (216).

[0086] Specifically, a 10.8mm wide ruler (158) from the comma-marked ruler group (150), and a 19mm wide ruler (149) from the millimeter-marked ruler group (140). Select , Next, the notched ruler (158) and notched ruler (149) are placed on the styrene board, and then the long sides of the notched ruler (158) and notched ruler (149) are brought into contact to produce a ruler (130) with a width of 29.8 mm. Then, this ruler (130) is used to cut the styrene board. By cutting, the 0.2 mm dimension (216) added by the blade thickness (214) is offset by a negative value of 0.2 mm due to the ruler's width dimension (130) being 29.8 mm, relative to the desired dimension of 30 mm, allowing the user to obtain a cutting result of 30 mm.

[0087] The second method involves first cutting the styrene board (S) to be cut using a ruler (130) of any desired size, and then cutting it using a ruler (130) with the desired size subtracted from the cut size.

[0088] If you require a 30mm cutting dimension as in the example above, for example, you would need to use the 50mm wide marking ruler (165) from the centimeter marking ruler group (160). Select, then place a 50mm wide notched ruler (165) on a styrene board (S) to manufacture a 50mm wide ruler, and then this ruler By using this to cut the styrene board (S), a styrene board (S) with dimensions of 50.2 mm can be obtained. Place it there. Next, The styrene board (S) Up 20mm wide ruler (162) By arranging these elements to manufacture a ruler (130) with a width of 20 mm, and then using this ruler (130) to cut the styrene board (S), Subtracting 20.2mm from 50.2mm, the user can obtain a cutting result of 30mm.

[0089] The third method involves offsetting the contact surface of the styrene board (S) and the contact surface of the ruler (130) by creating a step as a protrusion on the first contact surface where the styrene board (S) abuts and the second contact surface where the ruler (130) abuts, which are located on the side of the stopper (110), thereby correcting the dimension added by the blade thickness (214).

[0090] Next, the details will be explained below based on Figures 14, 15, 16, 17, and 18.

[0091] As shown in Figures 14 and 15, the stopper (110) is formed by combining the main body (111) and the slide plate (112), resulting in a stepped structure with protrusions on one vertical wall (219) of the lower slide plate (112), which serves as the first contact surface against which the styrene board (S) comes into contact, and on one vertical wall (116) of the upper main body (111), which serves as the second contact surface against which the ruler (130) comes into contact.

[0092] As shown in Figures 16(a) and 16(b), after bringing a styrene board (S) with a thickness of 2 mm into contact with the stopper (110), on the styrene board (S) By positioning a 30mm wide notched ruler (163) and bringing the notched ruler (163) into contact with a stopper (110), the ruler (130) is manufactured. The styrene board (S) is in contact with one vertical wall portion (219) of the slide plate (112) located at the bottom of the stopper (110), and the ruler (130) consisting of the notched ruler (163) is in contact with one vertical wall surface (116) of the main body (111) located at the top of the stopper (110).

[0093] As shown in Figure 17, in the stopper (110), a step is formed between the two contact surfaces (219, 116).

[0094] After bringing the styrene board (S) into contact with one of the vertical walls (219) of the slide plate (112) located at the bottom of the stopper (110), a 30mm wide marking ruler (163) is selected on the styrene board (S), and then the 30mm wide marking ruler (163) is placed on the styrene board (S) to manufacture a 30mm wide ruler (130), and this The long side of the ruler (130) , on one vertical wall surface (116) of the main body (111) located above the stopper (110) When brought into contact, Ruler with a width of 30mm (130) The opposite side of the long side is on the styrene board (S) In, This shows the value (225) after subtracting the offset value (221) due to the step difference. That will happen.

[0095] In this case, if the offset value of the step (221) is set to half the blade thickness (214) of the cutting tool (K) used for cutting, then when cutting with the cutting tool (K), a value (221) equal to the dimension (216) added by the blade thickness (214) of the cutting tool (K) is subtracted by the step. As a result, the user can obtain a cutting result (226) that is equal to the width dimension of the ruler (130) consisting of the marking ruler (163) selected as the desired dimension.

[0096] As an example, the case of using a stopper (110) to cut a styrene board (S) with a thickness of 2 mm to a desired dimension of 30 mm using a blade (K) with a blade thickness of 0.4 mm (214) will be explained below based on Figure 17.

[0097] First, at the contact surfaces (219, 116) of the stopper (110), the offset value (221) due to the step formed by one vertical wall portion (219) of the slide plate (112) and one vertical wall surface (116) of the main body (111) is set to 0.2 mm, which is half the blade thickness of the cutting tool (K), 0.4 mm (214).

[0098] After placing a styrene board (S) with a thickness of 2 mm against the stopper (110), a marking ruler (163) with a width of 30 mm is placed on the styrene board (S). Select this, then place a 30mm wide notched ruler (163) on a styrene board (S) to manufacture a 30mm wide ruler (130), and this The long side of the ruler (130) , on one vertical wall surface (116) of the main body (111) located above the stopper (110) When brought into contact, the styrene board (S) comes into contact with one vertical wall portion (219) of the slide plate (112) located at the bottom of the stopper (110), and the ruler (130) comes into contact with one vertical wall surface (116) of the main body (111) located at the top of the stopper (110).

[0099] The One vertical wall surface (116) of the upper body (111) to which the ruler (130) makes contact is offset (221) by 0.2 mm in the negative X-axis direction from one vertical wall portion (219) of the lower slide plate (112) to which the styrene board (S) makes contact. The ruler (130) isThe value obtained by subtracting the offset value (221) of 0.2 mm due to the step from the width dimension of 30 mm. That is The dimension of 29.8 mm is indicated on the styrene board (S).

[0100] In this state, when the styrene board (S) is cut vertically with a blade (K) having a blade thickness (214), the 0.2 mm dimension (216) added by the blade thickness (214) of the blade (K) is offset by a 0.2 mm dimension (221) due to the stopper's step, allowing the user to obtain a cut result of the desired dimension of 30 mm (226) using a 30 mm wide ruler (130).

[0101] Furthermore, the method described above, which compensates for the added dimension (216) due to the blade thickness (214) by using the step provided on the contact surface (219, 116) of the ruler (130) at the contact surface of the stopper (110), is only effective when the thickness (222b) of the styrene board (S) is greater than the thickness (112b) of the lower slide plate (112). When the thickness (222b) of the styrene board (S) is less than the thickness (112b) of the slide plate (112), the ruler (130), which consists of a notched ruler (163) placed on the styrene board (S), also contacts one of the vertical walls (219) of the lower slide plate (112) in the same way as the styrene board (S). Therefore, the set offset value (221) does not work effectively, and it is not a suitable method for dealing with the added dimension (216) due to the blade thickness (214).

[0102] If the thickness (222b) of the styrene board (S) is less than the thickness (112b) of the slide plate (112), then the first or second method described above for obtaining the desired cutting result is effective.

[0103] Next, referring to Figures 19 to 21, the procedure for adjusting the offset value (221) of the step formed by one vertical wall surface (116) on the main body (111) and one vertical wall portion (219) on the slide plate (112) of the stopper (110) will be explained using the marking rulers (140, 150, 160, 170).

[0104] Figure 19(a) shows the back side of the stopper (110). As shown in Figures 19(a) and 19(b), the stopper (110) comprises a slide plate (112) and a main body (111), the main body (111) comprising a base (113) and a protrusion (114). The slide plate (112) is fixed to the bottom (115) of the base (113) by a bolt (124) inserted through an elongated hole (125) from the inclined portion (118) side of the main body (111) into a screw hole (123). The elongated hole (125) has an adjustment range of 1 mm in the width direction of the base (113), and the fixing position of the slide plate (112) can be adjusted within a range of 1 mm in the width direction relative to the main body.

[0105] As shown in Figures 20(a) and 20(b), the width dimension (122) of the bottom (115) of the base (113), excluding the protrusion (114), is 45 mm. The width dimension (112w) of the slide plate (112) is 35mm, so the difference (229) between the width dimension (122) of the base (113) excluding the protrusion (114) at the bottom (115) is 10mm.

[0106] Therefore, when the distance (229) between the protrusion (114) and the slide plate (112) at the bottom (115) of the base (113) is 10 mm, the combined dimension (229) and the width dimension (112w) of the slide plate (112), which is 35 mm, is 45 mm. This is equal to the width dimension (122) of the bottom (115) of the base (113) other than the protrusion (114), which is 45 mm. As a result, no step is formed between one vertical wall portion (219) of the slide plate (112) and one vertical wall surface (116) of the main body, and the two contact surfaces (218) to which the styrene board (S) and the ruler (130) come into contact are on the same plane.

[0107] Therefore, if a gap (229) of 10 mm or more is provided between the protrusion (114) and the slide plate (112), the combined dimension (229, 112w) of the slide plate (112) and the width dimension (112w) of the slide plate (112), which is 35 mm, will be 45 mm or more. The portion of the base (113) bottom (115) that exceeds the width dimension (122) of 45 mm other than the protrusion (114) will be formed as a step between one vertical wall portion (219) of the slide plate (112) and one vertical wall surface (116) of the main body at the two contact surfaces (218) where the styrene board (S) and the ruler (130) come into contact.

[0108] As an example, the adjustment procedure for when an offset value of 0.2 mm is desired for the step difference between one vertical wall portion (219) of the slide plate (112) and one vertical wall portion (116) of the main body at two contact surfaces (218) where the styrene board (S) and ruler (130) come into contact is described below with reference to Figures 21(a) and 21(b).

[0109] From the comma-marked ruler group (150), the 10.2 mm marking ruler (152) is placed in the area between the convex part (114) and the slide plate (112) at the bottom (115) of the base (113), and both long sides (152a, 152b) of the 10.2 mm marking ruler (152) are placed in the convex part (114) and the slide plate (112), respectively. When manufacturing a ruler (130) by bringing them into contactThe distance (230) between the protrusion (114) and the slide plate (112) is 10.2 mm, and when combined with the width dimension (112w) of the slide plate (112) which is 35 mm, the combined dimension (230, 112w) is 45.2 mm.

[0110] The dimensions of the part in question (230, 112w) are such that the dimensions of the part exceeding 45 mm, which is the width dimension (122) of the bottom (115) of the base (113) excluding the protrusion (114), are 0.2 mm. At the two contact surfaces (218) where the styrene board (S) and the ruler (130) come into contact, a step with an offset value (221) of 0.2 mm is formed between one vertical wall portion (219) of the slide plate (112) and one vertical wall surface (116) of the main body.

[0111] In the above state, the slide plate (112) is fixed by screwing a bolt (124), which is inserted through an elongated hole (125) made in the main body (118), into a screw hole (123) in the slide plate (112), and a stopper (110) with a step of 0.2 mm is set on the two contact surfaces (218) that the styrene board (S) and the ruler (130) come into contact with.

[0112] In this way, the user can use the following methods to determine the offset value (221) between the two contact surfaces (218) where the styrene board (S) and the ruler (130) are in contact: one vertical wall portion (219) of the slide plate (112), one vertical wall portion (116) of the main body, and the notched ruler (140, 150, 160, 170). A ruler (130) manufactured using It allows for precise adjustments.

[0113] Also, By using a ruler (130) with a comma-marked ruler (150) to set the offset value (221) at the two contact surfaces (218) where the styrene board (S) and the ruler (130) come into contact, Adjustments can be made in 0.1mm increments.

[0114] In the embodiment of the present invention, the stopper (110) is made of metal, but it does not have to be made of metal.

[0115] As shown in Figure 7, the stopper (110) of the embodiment of the present invention has a bottom portion (245, 246) that is processed to prevent slipping, such as knurling. However, the means of preventing slipping is not limited to anti-slip processing, and if it is not convenient, anti-slip measures may not be provided.

[0116] As shown in Figure 9, in this embodiment, the width dimension (112w) of the slide plate (112) constituting the stopper (110) is 35 mm, and the adjustment range of the fixed position by the elongated hole (125) formed in the main body (111) is 1 mm. Therefore, the adjustable numerical range of the step difference between the first contact surface and the second contact surface is from 0 mm to 1 mm. However, the adjustment range provided in the elongated hole (125) is not limited to 1 mm, and the width dimension (112w) of the slide plate (112) is not limited to 35 mm, so the adjustable numerical range of the step difference is not limited to 0 mm to 1 mm.

[0117] The step difference between the first contact surface and the second contact surface provided on the stopper (110) of the present invention is not limited to the purpose of correcting the additional dimension (216) caused by the blade thickness (214) of the cutting tool (K) used, but may also be used to set other correction values ​​for desired dimensions.

[0118] Although the slide plate (112) in this embodiment is a plate-like body, as shown in Figure 18, a recess may be provided on the upper side of the slide plate end (112d), and the thickness of the end (112d) may be reduced. As a result, even if the thickness (223b) of the styrene board (S) is thinner than the thickness of the slide plate base (112b), if the thickness (223b) of that part is greater than or equal to the thickness (112c) of the end (112d) of the slide plate, the notched ruler (163) in Figure 18 Manufactured using As shown by the ruler (130), the ruler (130) does not come into contact with one vertical wall portion (219) of the slide plate (112), but rather with one vertical wall surface (116) of the main body (111), allowing the offset value (221) set for the stopper (110) to function effectively.

[0119] If the user does not need to correct the dimensional values ​​due to the steps provided on the two contact surfaces (219, 116) of the stopper (110), the user may use the other vertical wall surface (117) that is erected from the other side of the protrusion (114) on the bottom (115) of the main body (111) of the stopper (110) as the contact surface between the ruler (130) and the styrene board (S), as shown in Figure 9.

[0120] The body (111) of the stopper (110) in the embodiment of the present invention is provided with an inclined portion (118) extending from a vertical wall surface (116) to the upper surface (119). However, the dimensions and angle of this portion are not limited, and the inclined portion (118) may be omitted if it is not convenient for the cutting operation, in which the ruler (130) and the styrene board (S) to be cut are held down and fixed from above by hand. [Industrial applicability]

[0121] The ruler (130) of the present invention is typically used to cut styrene board (S), which is used in the production of architectural models, to a predetermined width. However, the instrument (100) of this embodiment is not limited to cutting styrene board (S), and may also be used to cut other sheet materials such as paper, cloth, film, cellophane sheets, cutting color sheets, wood, wood sheets, design sheets, wood grain sheets, rubber sheets, plastic sheets, corrugated plastic, polyvinyl chloride sheets, acrylic sheets, polycarbonate sheets, fluororesin sheets, polypropylene resin sheets, leather sheets, synthetic leather sheets, felt sheets, magnetic sheets, carpets, masking tape, adhesive tape, etc.

[0122] The ruler (130) of the present invention can be used not only for cutting but also for marking lines and other line drawing tasks.

[0123] The ruler (130) of the present invention can be used, for example, when determining the spacing or position of components of a device, by using the ruler (130) itself or a copy of the ruler (130) as a spacer. [Explanation of Symbols]
