Description

Technical Field

[0001] The present invention relates to, for example, a seedling sheet used when planting seedlings in a field or the like, a seedling sheet manufacturing apparatus, a seedling sheet manufacturing method, and a seedling sheet manufacturing program.

Background Art

[0002] Conventionally, in order to grow and cultivate plant seedlings in a field or the like, a "ridge" is made by raising soil in a long and straight shape in the field or the like, and plants are grown and cultivated on this ridge. In addition, in order to grow and cultivate seedlings in a field or the like, a unique growth area corresponding to each type of seedling is required. This growth area is a unique area in which each individual seedling can grow without substantial interference from other adjacent seedlings as it grows. However, when arranging seedlings on the ridge, it is difficult to plant each seedling while ensuring this unique growth area. Particularly, when planting seedlings as a hobby in a home garden or the like, it has been particularly difficult.

[0003] Therefore, in this ridge, a seedling sheet having a large number of openings such as circular shapes is used to ensure the unique growth area of each individual seedling (for example, Patent Document 1). The size of the openings such as circular shapes arranged in this seedling sheet is, for example, about 60 mm, and is formed by perforations or the like. When the user removes the sheet along the perforations, an opening for planting seedlings is formed. Therefore, when the user plants a plant in this opening, the seedling can ensure a growth area where it is not interfered with by other adjacent seedlings. In order to ensure the growth areas of these various seedlings, it is necessary to form a gap of, for example, about 150 mm between each opening.

Patent Document 1

[0005] On the other hand, these seedling sheets are formed to match the shape of the ridges, and the standard dimensions in the market are, for example, a strip shape with a short side of 950 mm and a long side of 50 m, with five openings formed along each short side. If five openings are formed in parallel along the shorter side of a standard-sized seedling sheet to secure a growing area, the area at the bottom edge of the sheet along the shorter side will inevitably become smaller. The bottom edge of the seedling sheet is an important part that, when placed on a ridge, is covered with soil from the field or other area to maintain the agricultural sheet in a properly stretched state. Therefore, if the area at the bottom of the sheet is small, the seedling sheet will sag, making it difficult to place the seedlings in the correct position. Furthermore, in order to ensure sufficient space at the bottom edge of the seedling sheet, it was necessary to reduce the number of openings placed along the shorter side of the sheet while securing the growing area. This meant that it was not possible to place five openings along the shorter side of a standard-sized seedling sheet, which led to a decrease in customer satisfaction.

[0006] Therefore, the present invention aims to provide a seedling sheet, a seedling sheet manufacturing apparatus, a seedling sheet manufacturing method, and a seedling sheet manufacturing program that, in a standard type seedling sheet of a standard size in the market, appropriately secures the area of ​​the bottom portion while not reducing the number of openings in the short side direction of the sheet.

[0007] The above objective is achieved by a seedling sheet according to the present invention, which has a fixing part for fixing to a placement location and a plurality of openings for arranging plant seedlings, each of the openings forms a growing area around it for growing the seedlings placed in the opening, and is arranged so as not to interfere with the growing areas of the seedlings in other openings, the growing areas of adjacent openings are arranged to be in contact with each other, the openings are arranged in a plurality of rows, the openings in each row are arranged alternately with the openings in other adjacent rows, the second row of openings is arranged alternately with the first row of openings and the third row of openings which are groups of openings in the same row, the distance between the openings in the row direction is longer than the distance between the openings between the first row and the third row, and the growing areas of the openings in the first row, the second row of openings and the third row of openings are arranged to be in contact with each other.

[0008] According to the above configuration, a cultivation area for growing seedlings placed in the opening is formed around it, and is arranged so as not to interfere with the cultivation areas of seedlings in other openings. Therefore, the growth of seedlings planted in the opening is not hindered by other seedlings. Furthermore, the growing areas of adjacent openings are arranged to be in contact with each other, and multiple openings are arranged in rows. The openings in each row are arranged alternately with the openings in other adjacent rows, and the group of openings in the second row, which is arranged alternately with the first group of openings and the third group of openings, is located within the area formed by these two groups. In other words, the second row of openings is arranged in an alternating pattern (such as a staggered pattern) in the region between the first row of openings and the third row of openings, and the openings are densely arranged so that their growth areas are in contact with each other.

[0009] Therefore, without being affected by other seedlings, it is possible to secure the growing area for each opening while arranging the openings more efficiently within the same area as before. For example, while conventional designs arrange five openings in parallel in a single row, the above configuration makes it possible to arrange five openings across the width of three rows. Therefore, the area of ​​the fixed portion (such as the bottom edge) of the seedling sheet can be increased, and the seedling sheet can be placed in a state where it is stretched tightly over ridges, etc., so that the openings can be appropriately positioned relative to the ridges, and seedlings can be grown effectively.

[0010] Furthermore, according to the above configuration, the distance between openings in the row direction is longer than the distance between openings between the first row and the third row. Furthermore, the growth regions of the openings in the first row (Z1, etc.), the growth regions of the openings in the second row (W1, etc.), and the growth regions of the openings in the third row (U1, etc.) are arranged to be in contact with each other. Therefore, the distance between rows (such as the first to third rows) can be shortened, and the same number of openings can be secured within the same area as conventional seedling sheets, resulting in seedling sheets that are easy for users to use.

[0011] Preferably, the opening of the seedling sheet is formed by cutting along perforations.

[0012] According to the above configuration, an opening can be easily formed by cutting along the perforations.

[0013] Preferably, the seedling sheet is characterized in that a removal assist portion is formed on the outside of or on a part of the perforations.

[0014] According to the above configuration, by forming a slit or other removal aid in addition to the perforations, even when the user cannot visually confirm the position using only the perforations, the removal aid makes it visible, thus providing a "marker" effect. Furthermore, the "removable support section" makes it easier to cut along the "perforations."

[0015] According to the present invention, the above object is achieved by a cylinder part having a sewing machine blade part for forming a sewing line of an opening of a seedling sheet, and a receiving part for receiving the sewing machine blade part, wherein the receiving part is formed with a receiving part for accommodating the sewing machine blade part after the sewing line is formed on the seedling sheet by the sewing machine blade part, and is characterized by a seedling sheet manufacturing apparatus.

[0016] According to the above configuration, since the receiving part (such as a receiving base) has a receiving part (such as a blade receiving groove) for accommodating the sewing machine blade part after the sewing line is formed on the seedling sheet by the sewing machine blade part, when forming the sewing line on a plurality of seedling sheets simultaneously, the sewing line can be formed evenly.

[0017] Preferably, a blade part for forming a removal auxiliary part is detachably arranged on the cylinder part of the seedling sheet manufacturing apparatus, and is characterized by having a protruding position adjusting part capable of adjusting the blade part for forming the removal auxiliary part to an arbitrary position.

[0018] According to the above configuration, when only the blade of the blade part for forming the removal auxiliary part is changed to an acute angle, an obtuse angle, etc., while the sewing machine blade part remains as it is, the blade can be changed only by adjusting with the protruding position adjusting part, and there is no need to change the protruding position of the entire blade as in the prior art, etc., and the changing operation, etc. becomes easy.

[0019] Preferably, the blade part for forming the removal auxiliary part of the seedling sheet manufacturing apparatus is arranged adjacent to the sewing machine blade part, and at least in the adjacent region between the blade part for forming the removal auxiliary part and the sewing machine blade part, the tip of the cutting edge of the sewing machine blade part and the tip of the cutting edge of the blade part for forming the removal auxiliary part are arranged to overlap.

[0020] According to the above configuration, in the adjacent region between the blade part for forming the removal assisting part and the perforation blade part, the tip of the blade tip part of the perforation blade part and the tip of the blade tip part of the blade part for forming the removal assisting part (such as a slit blade part) are arranged to overlap. Therefore, an auxiliary removal part can be accurately formed adjacent to the perforation or on a part of the perforation in the seedling sheet.

[0021] According to the present invention, the object is achieved by a method for manufacturing a seedling sheet, which includes a cylinder part having a perforation blade part for forming a perforation in an opening of the seedling sheet, and a receiving part for receiving the perforation blade part. After forming the perforation in the seedling sheet with the perforation blade part, the perforation blade part is accommodated in the accommodation part of the receiving part.

[0022] According to the present invention, the object is achieved by a seedling sheet manufacturing program for a seedling sheet manufacturing apparatus, which includes a cylinder part having a perforation blade part for forming a perforation in an opening of the seedling sheet, and a receiving part for receiving the perforation blade part. After forming the perforation in the seedling sheet with the perforation blade part, the function of accommodating the perforation blade part in the accommodation part of the receiving part is realized.

Advantages of the Invention

[0023] As described above, the present invention has the advantage of providing a seedling sheet, a seedling sheet manufacturing apparatus, a seedling sheet manufacturing method, and a seedling sheet manufacturing program that can appropriately secure the area of the hem part while reducing the number of openings in the short side direction of the sheet in a standard-sized seedling sheet in the market.

[Figure 2] It is a schematic enlarged view of the opening Z in FIG. 1. [Figure 3]This is a schematic diagram showing a conventional home garden sheet 1000. [Figure 4] (a) is a schematic diagram showing the relationship between openings Y, Z, W, and U in Figure 1, and (b) is a schematic diagram showing the relationship between the center points of openings Z, U, and W. [Figure 5] This is a schematic diagram showing a seedling sheet 50, which is another example of a seedling sheet with standard dimensions similar to the seedling sheet 1 according to this embodiment. [Figure 6] This is a schematic diagram showing the main components of "Home Garden Sheet Manufacturing Device 100," which is an example of a seed and seedling sheet manufacturing device. [Figure 7] This is a schematic diagram illustrating the protruding position of the slit blade portion 130. [Figure 8] Figure 5 is a schematic diagram showing the arrangement of the cutting edges of the perforation blade 120 and the slitting blade 130. [Modes for carrying out the invention]

[0025] Hereinafter, preferred embodiments of this invention will be described in detail with reference to the accompanying drawings and other materials. The embodiments described below are preferred examples of the present invention and are subject to various technically preferred limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise stated in the following description.

[0026] (Main components of home garden sheet 1) Figure 1 is a schematic diagram showing "Home Garden Sheet 1," which is an example of a seedling sheet according to this embodiment. As shown in Figure 1, the home garden sheet 1 is, for example, a strip-shaped sheet made of polyethylene, with a short side 1a of, for example, 950 mm, long sides 1b and 1c of 50 mm, and a thickness of 0.02 mm to 0.03 mm.

[0027] This garden sheet 1 is the most in-demand size on the market, and this size is the standard size for garden sheet 1. Furthermore, Sheet 1 has multiple openings X to U, etc., which allow the user to place it on a "ridge," which is an example of a location for a home garden, and plant seedlings of plants such as carrots and onions at appropriate intervals.

[0028] (Main components of opening X, etc.) Figure 2 is a schematic enlarged view of the opening Z in Figure 1. As shown in Figure 2, the opening Z of the sheet 1 is formed by perforations P, and the sheet portion covering the opening Z (inside the perforations P) can be easily removed by pressing the perforations P or the vicinity thereof with the user's fingers when using it (for example, after stretching it out on the furrows of a home garden).

[0029] As shown in Figure 2, this perforation P has alternating "small holes P1" and "connecting parts P2," and the "small holes P1" are formed in an oval shape. The length of the "small hole P1" of this perforation P is, for example, 3 mm, and the length of the short side is, for example, 1 mm. Furthermore, the longitudinal dimension of the "connecting portion P2" of the perforation P is 0.6 mm to 0.8 mm. By forming perforations P on the sheet 1, which have small holes P1 and connecting parts P2 within a specified numerical range, the sheet can be easily removed by the user through the perforations P.

[0030] (Main components of Slit S) Furthermore, in this embodiment, as shown in Figure 2, a "slit S," which is an example of a removal assist part, is formed on the outside of or on a part of the perforation P. As shown in Figure 2, in this embodiment, the slit S is an arc-shaped elongated hole adjacent to the outside of the perforation P, with a length of approximately 1 mm in the short direction and approximately 15 mm in the long direction, which is significantly larger than the 3 mm small hole P1 of the perforation P.

[0031] Furthermore, as shown in Figure 1, when the sheet 1 is positioned with the short side 1a in the vertical direction and the long sides 1b and 1c in the horizontal direction, it is preferable to form the "slit S" above the perforation P of the opening X, etc. In this way, by placing the "slit S" adjacent to the outside of the "perforation P," the user can easily cut the perforation P by pressing their finger on the area where the slit S is located, and the user can more easily form an opening X, etc.

[0032] Furthermore, by forming the slit S, even when the user cannot visually confirm the position of the perforation P alone, the slit S makes it visible, thus providing a "marker" effect. Unlike this embodiment, if the "slit S" is formed as part of the "perforation P", the "perforation P" can be cut more easily.

[0033] (Main components of the hem section 1d, etc.) As shown in Figure 1, the openings X, etc., are arranged in an alternating pattern (e.g., staggered). As shown in Figure 1, "hem portions 1d and 1e," which are examples of fixing portions, are formed on both ends (left and right ends) in the direction of the long sides 1b and 1c of the sheet 1. These hems 1e and 1d each have a width of approximately 185 mm, for example, and the sum of the lengths on both sides is 370 mm, which is 38.9% of the width of the short side 1a of sheet 1, which is 950 mm.

[0034] Therefore, by placing field soil at these lower edges 1d and 1e, the sheet 1 can be positioned to cover the "ridges" while being stretched taut. Furthermore, since the openings X, etc., are appropriately positioned in the predetermined locations, the user can plant the seeds and seedlings in the correct locations.

[0035] Figure 3 is a schematic diagram showing a conventional home garden sheet 1000. As shown in Figure 3, the home garden sheet 1000, like the home garden sheet 1 of this embodiment, has a short side 1000a with a length of 950 mm and long sides 1000b and 1000c with lengths of 50 m. Conventionally, five openings 1001a, 1001b, 1001c, 1001d, and 1001e are arranged in parallel along the short side 1000a of such a home garden sheet 1000.

[0036] In the case of a home garden sheet 1 with a short side of 1000a measuring 950mm, the most in-demand and standard sheet 1000 has five openings 1001a etc. arranged along the short side 1000a. Then, when five openings 1001a, etc., are arranged in parallel on the sheet 1000, as shown in Figure 3, the total length of the hems 1000d and 1000e on both sides is "290 mm", which is only about "30.5%" of the sheet 1000's width of 950 mm.

[0037] Even when soil is placed on the bottom edges 1000d and 1000e of the sheet 1000, the bottom edges 1000d, etc., do not function sufficiently as fixing points, making it impossible to stretch the sheet 1000 tightly over the ridge. As a result, there was a problem in that the openings 1001a, etc., could not be properly positioned on the ridge.

[0038] In this respect, in this embodiment, the proportion of the hem portion 1d, etc., shown in Figure 1 is "38.9%", which is significantly larger than the "30.5%" of the conventional hem portion 1000d, etc., and the function of the hem portion 1d, etc., as a fixing part is greatly improved.

[0039] (Specific configuration of the arrangement of openings X, etc.) In this embodiment, as shown in Figure 1, openings X, etc., are arranged alternately (in a staggered pattern) in the region sandwiched between the hems 1d and 1e of the sheet 1.

[0040] (1st column) Specifically, as shown in Figure 1, three openings X, Y, and Z are arranged in the direction of the short side 1a of the sheet 1, each spaced, for example, 260 mm apart, to form the first row (an example of the group of openings in the first row). Then, around each of these openings X, Y, and Z, growth areas X1, Y1, and Z1 are formed for the seedlings planted in opening X, etc. (shown by dashed lines in the figure).

[0041] This cultivation area X1, etc., is a unique area where individual seedlings can grow without significant interference from neighboring seedlings. Furthermore, the growth areas X1, Y1, and Z1 are each regions with a radius of, for example, 75 mm from the center of the opening X, etc.

[0042] (2nd column) Below this first row, opening V is located diagonally below openings X and Y, between openings X and Y, and opening W is formed diagonally below openings Y and Z, between openings Y and Z. The distance between these openings V and W is 260 mm, forming a second row (an example of a group of openings in the second row).

[0043] Growth regions V1 and W1 (dashed lines) are also formed in the openings V and W that make up the second row, respectively. Growth regions V1, etc. are positioned to be in contact with growth regions X1 and Y1 of the first row, and growth region W1 is positioned to be in contact with growth regions Y1 and Z1 of the first row.

[0044] (3rd column) Below these second rows, as shown in Figure 1, an opening S is positioned diagonally below opening V, and an opening T is formed diagonally below openings V and W. Furthermore, an opening U is formed diagonally below the opening W, and these openings S, T, and U constitute a third row (a group of openings in the third row), with each opening spaced 260 mm apart.

[0045] Furthermore, growth regions S1, T1, and U1 are formed in the openings S, T, and U that make up these three rows, respectively. These growth regions S1, T1, and U1 are adjacent to the growth regions X1, etc., in the first and second columns, respectively. Specifically, training area S1 is adjacent to training area X1 in the first column and training area V1 in the second column, while training area T1 is adjacent to training area Y1 in the first column and training areas V1 and W1 in the second column. Furthermore, development area U1 is adjacent to development area Z1 in the first column and development area W1 in the second column.

[0046] (Relationship between columns 1, 2, and 3, etc.) Thus, in this embodiment, the first growth area X1, the second growth area V1, and the third growth area S1 are in a relationship where they are adjacent to each other. In other words, the growth regions X1 etc. in the first, second, and third columns are arranged so as to be adjacent to the growth regions X1 etc. in the other two columns. Therefore, the growth regions X1, Y1, and Z1 in the first column and the growth regions S1, T1, and U1 in the third column are all adjacent to each other.

[0047] Furthermore, the distance between openings X, etc. in the same row (260 mm) is longer than the distance between openings Z, U, etc. in different rows, such as the first row and the third row. Specifically, the distance between openings Z, U, etc. in the first and third rows is the same as the length of one growth area Z, etc. (150 mm), and the distance between openings Z, Y, etc. in the same row (first row, etc.) (260 mm) is longer than this length.

[0048] Although not shown in Figure 1, etc., the fourth column and subsequent columns of Sheet 1 are formed in the same way as the first to third columns. In this embodiment, as described above, the growth areas X1, etc., of each opening X in the first to third rows are configured to be in contact with each other. Therefore, for example, in Figure 1, the growth area Z1 of opening Z, the growth area U1 of opening U, and the growth area W1 of opening W are all the same length, with the distance from the center of each opening being 150 mm.

[0049] By arranging them in this way, even if the openings X etc. are arranged in a staggered pattern (alternating) as shown in Figure 1, it is possible to secure the growth areas X1 etc. for all openings X etc. without interfering with other growth areas X1 etc.

[0050] (Conventional home garden sheet 1000, including the opening 1001a, etc.) As shown in Figure 3, in the conventional seedling sheet 1000, five openings 1001a, etc., are arranged in a row along the shorter side 1000a direction, and each row is arranged similarly, so the openings 1001a, etc., are arranged in a grid pattern.

[0051] In standard seedling sheets 1000, five openings 1001a, etc., are often arranged in the direction of the shorter side 1000a, and customers also request this configuration, so we had no choice but to arrange five openings in the direction of the shorter side 1000a. Therefore, as described above, the areas of the "hem portions 1000d and 1000e" on both sides, which are positioned along the long sides 1000c and 1000d of the sheet 1000, are narrow. As shown in Figure 3, when the short side 1000a is the standard 950 mm, only 145 mm can be secured for the hem portions 1000d and 1000e on both sides. As a result, even if soil is placed on the hem portions 1000d, the fixing function of the sheet 1000 is not fully realized.

[0052] In this respect, in this embodiment, as described above, since only three or two openings X are arranged as an example, a sufficient "hem portion 1d, 1e" can be secured and the fixing function can be fully performed (Figure 1).

[0053] On the other hand, in this embodiment, since only three or two openings X etc. are arranged in a row of the sheet 1, the number of openings X etc. appears to be reduced compared to the conventional example in Figure 3 where there are five openings X etc. in a row of the sheet 1000. However, as shown in Figure 3, the conventional sheet 1000 requires, for example, "150 mm" between each opening 1001a, etc., considering the growth area as described above.

[0054] In this respect, in this embodiment, even if there are three openings X etc. in the first row, by arranging two rows of openings V etc. (second row) in the intermediate region between the next three rows of openings U etc. (third row) arranged at 150 mm intervals in the long sides 1b and 1c directions of the sheet 1, it is possible to arrange the same five openings X etc. as in the conventional method at 150 mm intervals.

[0055] Furthermore, even with this arrangement, as described above, the growth areas X1 of each opening X are secured, and the configuration ensures that they do not interfere with one another. Furthermore, in this embodiment, as shown in Figure 1, by arranging the openings X, etc., it is possible to arrange five openings X, etc., similar to those in the conventional design, within the length between the first and second rows. In other words, in this embodiment, the distance between rows (the first to third rows, etc.) can be shortened, and the same number of openings X, etc. can be secured within the same area as conventional home garden sheets 1 (between the first and second rows), resulting in a home garden sheet 1 that is easy for the user to use.

[0056] In this embodiment, for the sake of explanation, the three openings X, Y, and Z in Figure 1, etc., are referred to as the first row, the two openings V and W as the second row, and the three openings S, T, and U as the third row. However, as described above, the five openings X, etc., in the first and second rows combined correspond to the conventional single row in Figure 3 (five openings 1001a, 1001b, 1001c, and 1001e). Therefore, in actual transactions of the seedling sheet 1, the first and second columns of this embodiment are collectively referred to as "the first column," and the third column and the fourth column below it are collectively referred to as "the second column." In this case, as shown in Figure 1, the lengths between the five openings X, V, Y, W, and Z will all be the same, "130 mm".

[0057] (Theoretical explanation of the arrangement of openings X, etc.) Figure 4 is a schematic diagram illustrating the theory of the arrangement of openings X, etc., in this embodiment. Figure 4(a) is a schematic diagram showing the relationship between openings Y, Z, W, and U in Figure 1, and Figure 4(b) is a schematic diagram showing the relationship between the center points of openings Z, U, and W.

[0058] As shown in Figure 4(a), by positioning the opening W midway between openings Y and Z, the length of b in Figure 4(b) becomes 130 mm. Furthermore, by arranging the growth areas Z1 of openings Z, U, and W so that they are adjacent to each other, the distance (L) between opening W and opening Z will also be 150 mm.

[0059] Figure 5 is a schematic diagram showing a seedling sheet 50, which is another example of a seedling sheet with standard dimensions similar to the seedling sheet 1 according to this embodiment. The seedling sheet 51 shown in Figure 5 shares many components with the seedling sheet 1 described above. Therefore, the explanation of the common parts will be omitted, and the explanation will focus on the differences. Seedling sheet 50 has a shorter side 51a of "1350 mm", which is longer than the shorter side of sheet 1, which is "950 mm". Therefore, it has more openings than the three openings X, Y, Z in the first row of sheet 1, and has four openings X, Y, Z, and R.

[0060] Furthermore, it has more openings than the two openings V and W in the second row of the same sheet 51a, and has three openings V, W, and Q. Furthermore, it has more openings than the three openings S, T, U in the third row of sheet 1, and has four openings S, T, U, O. Furthermore, the length of each of these openings X, etc., is the same as that of sheet 1, "130 mm".

[0061] Furthermore, the hems 51d and 51e of the sheet 50 are each 255mm long, and when added together they make 510mm, which is 37.8% of the sheet 50's short side of 1350mm. Similar to the sheet 1 described above, by placing soil or other material on the hems 51d and 51e, the sheet 50 can be positioned to cover the "ridges" while being stretched taut. In other words, the hems 51d, etc., function effectively as fixing points.

[0062] As shown in Figure 5, the seedling sheet 50 is configured to produce the same effects and benefits as the seedling sheet 1 described above, except that the length of the short side 51a and the number of openings X differ from those of the sheet 1. Also, similar to the aforementioned Sheet 1, in the trading of Seedling Sheet 50, the first and second columns are collectively referred to as "Column 1," and the third column and the fourth column below it are collectively referred to as "Column 2." In this case, as shown in Figure 5, the lengths between the seven openings X, V, Y, W, Z, Q, and R are all the same, "130 mm".

[0063] (Configuration of the home garden sheet manufacturing device 100) Figure 6 is a schematic diagram showing the main components of "Home Garden Sheet Manufacturing Device 100," which is an example of a seed and seedling sheet manufacturing device. As shown in Figure 6, the home garden sheet manufacturing apparatus 100 includes a cylinder section 110, a perforation blade section 120 for forming perforations P in the home garden sheet 1, and a blade section holder section 111 for holding the perforation blade section 120.

[0064] The blade holder portion 111 of the manufacturing apparatus 100 is configured to hold the perforation blade portion 120 and to detachably hold a "slit blade portion 130," which is an example of a blade portion for forming a removable auxiliary portion. Specifically, the slit blade portion 130 is fixed to the blade portion holder portion 111 by a "slit blade holding portion 140," which is an example of a protruding position adjustment portion.

[0065] Furthermore, the slit blade holder 140 is configured such that the position of the slit blade 130 protruding from the home garden sheet 1 can be adjusted to any desired position by using screws or the like (arrow h in Figure 6).

[0066] Figure 7 is a schematic diagram illustrating the protruding position of the slit blade portion 130. As shown in Figure 6, when the cutting edge of the slit blade portion 130 is obtuse, the length l1 of the cutting edge is short, as shown in the slit blade portion 131 in Figure 7. On the other hand, when the cutting edge is acute, the length l2 of the cutting edge is long, as shown in the slit blade portion 132 in Figure 7. Thus, the position of the protruding cutting edge changes depending on the type of cutting edge of the slit cutting edge portion 130.

[0067] Therefore, in this embodiment, the slit blade holder 140 adjusts the protruding position of the slit blade portion 130 depending on whether the blade tip is obtuse or acute, so that it can be adjusted to be the same as the perforation blade portion 120. It has a functional configuration (arrow h in Figure 6).

[0068] In this respect, with the conventional configuration, changing the cutting edge of the slit blade portion 130 would change its protruding position, so the perforation blade portion 120 also needed to have its protruding position adjusted accordingly. However, in this embodiment, adjustment of only the slit blade portion 130 is sufficient, making it easy to adjust the cutting edge.

[0069] By the way, as shown in Figure 6, the blade portion of the perforation blade 120 is 3 mm, and the spacing between the blade portions of the perforation P is formed to be 0.6 to 0.8 mm. Therefore, as shown in Figure 2, the perforation hole P1 of the perforation P is formed to be 3 mm, and the connecting part P2 is formed to be 0.6 mm to 0.8 mm, making it easy for the user to cut the perforation P, while at the same time, when there is no need to cut the perforation P, it remains as is without being cut.

[0070] Figure 8 is a schematic diagram illustrating the arrangement of the cutting edges of the perforation blade portion 120 and the slit blade portion 13 in Figure 6. As shown in Figure 8, the cutting edge of the perforation blade 120 and the cutting edge of the slit blade 13 in Figure 6 are arranged so that their tips, for example, the cutting edges, overlap each other. Therefore, as shown in Figure 2, the perforations P and slits S can be formed in close proximity with high precision.

[0071] Unlike this embodiment, if the perforation blade portion 120 and the slitting blade portion 130 are arranged to be in closer contact, a slit S can be formed on the perforation P. Furthermore, as shown in Figure 6, the home garden sheet manufacturing apparatus 100 has, for example, about six "home garden sheets 1" on which perforations P and slits S are formed, and also has a "receiving stand 150" which is an example of a receiving part that receives the perforation blade 120 and the slit blade 130.

[0072] As shown in Figure 6, this support base 150 has a "blade receiving groove 151", which is an example of a housing section. Therefore, when the gardening sheet 1 is placed on the device 100 in Figure 6, and the cylinder part 110 moves downward from above in Figure 6, the perforation blade part 120 and the slit blade part 130 come into contact with the sheet 1, forming perforations P and slits S, and are then housed in the blade receiving groove 151 located below them.

[0073] This configuration prevents the perforating blade 120 and the slitting blade 130 from colliding with the support base 150, thereby preventing deterioration of the support base 150. Furthermore, compared to the conventional method where the perforating blade contacts a support base to form perforations P in the sheet 1, in this embodiment, where the perforating blade 120 and the slitting blade 130 are housed in the blade receiving groove 151, perforations P and slits S can be formed evenly on multiple, for example, six, home garden sheets 1.

[0074] By operating such a home garden sheet manufacturing apparatus 100, perforations P and slits S shown in Figure 1 and other figures can be formed accurately on the home garden sheet 1.

[0075] Furthermore, in this embodiment, the home garden sheet manufacturing apparatus 100 may be equipped with a computer having a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a hard disk, etc., and may be configured to be connected via a bus. In this case, the configuration is such that perforations P and slits S are formed in the home garden sheet 1 according to computer instructions.

[0076] In the embodiments described above, the example given was that the invention is implemented as a device. However, the present invention is not limited thereto, and the invention may be stored and distributed as a program that can be executed by a computer on a storage medium such as a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a magneto-optical disk (MO), or a semiconductor memory.

[0077] Furthermore, the storage medium only needs to be capable of storing programs and be readable by a computer. The storage format of the storage medium is not particularly limited.

[0078] Furthermore, an operating system (OS) running on a computer, or middleware (MW) such as database management software or network software, may execute some of the processes necessary to realize this embodiment based on instructions from a program installed on the computer from a storage medium.

[0079] Furthermore, the storage medium in this invention is not limited to a medium independent of the computer, but also includes a storage medium that stores or temporarily stores programs that have been downloaded via a LAN, the Internet, or the like.

[0080] Furthermore, the computer in this invention only needs to execute each process in this embodiment based on a program stored in a storage medium, and may be a device consisting of a single personal computer or the like, or a system in which multiple devices are connected via a network.

[0081] Furthermore, the term "computer" in this invention is not limited to personal computers, but also includes arithmetic processing units, microcontrollers, and the like included in information processing equipment, and refers collectively to any equipment or device capable of realizing the functions of this invention through a program.

[0082] Embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or combined in any way different from those described above. [Explanation of symbols]
