Description

[Technical field]

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

[0002] Conventionally, in order to grow and cultivate plant seeds and seedlings in a field or the like, long, narrow, linear piles of soil are made in the field or the like to form "ridges," and the plants are grown and cultivated in these ridges. Furthermore, in order to grow and cultivate seeds in fields or the like, a specific cultivation area is required for each type of seed. The growing area is a unique area in which each seedling can grow unhindered without substantial interference from adjacent seedlings. However, when arranging the seeds in the furrows, it is difficult to plant each type of seedling while securing this specific growing area, which is particularly difficult when planting seeds as a hobby in a home garden or the like.

[0003] Therefore, in order to ensure a unique growing area for each seedling in the ridges, a seedling sheet having a large number of openings, for example, circular openings, is used (for example, Patent Document 1). The size of the circular or other openings on this seed sheet is, for example, about 60 mm and is formed by perforations, etc., so that the user can remove the sheet along the perforations to create an opening for planting the seeds. Therefore, when a user plants a plant in this opening, the seedling can have a growing area that is not interfered with by other adjacent seedlings. In order to ensure a growing area for these various seedlings, it is necessary to form a gap of, for example, about 150 mm between each opening. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4202307 Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, this seed sheet is formed to fit the shape of the ridges, and the standard dimensions in the market are, for example, a strip-like 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 short side of such a seedling sheet of standard dimensions to ensure a cultivation area, the bottom area, which is the end portion of the sheet along the short side, will have less vigor. The bottom part of the seedling sheet is an important part for covering it with soil from the field, etc. when the seedling sheet is placed on the ridges, and for maintaining the agricultural sheet in an appropriately taut state. Therefore, if the bottom area is small, the seed sheet sags, making it difficult to place the seedlings in the appropriate positions. Furthermore, in order to ensure sufficient space at the bottom of the seedling sheet, it was necessary to reduce the number of openings placed along the short side of the sheet while still ensuring a growing area.However, this meant that it was not possible to place five openings along the short side of a standard-sized seedling sheet, resulting in a decrease in customer satisfaction.

[0006] Therefore, the present invention aims to provide a seed sheet, a seed sheet manufacturing device, a seed sheet manufacturing method, and a seed sheet manufacturing program that properly secures bottom area in a standard seed sheet that is a standard size on the market without reducing the number of openings in the short side direction of the sheet.

[0007] The object, according to the present invention, is to In the furrows Hem for fixing Department and , multiple for placing plant seeds Circular and a seedling growing section for growing the seedlings placed in the openings around each of the openings. Ring-shapedA belt-shaped seed sheet having a growth area and a plurality of short sides and a plurality of long sides, The openings and their growth regions are arranged in a row along the short side direction, and the rows are arranged consecutively along the long side direction starting from a first row which is the row arranged closest to one of the short sides, the growth regions in the same row are arranged at intervals from each other, the growth regions in the odd rows abut each other at their outer edges without overlapping with the growth regions in the even rows and other odd rows, and the growth regions in the even rows abut the outer edges of the growth regions in the odd rows, The distance between the openings in the column direction is of the distance between the openings in the first row and the second row is longer than the distance between the openings in the second row Distribution This object is achieved by a seed sheet, which is characterized by being placed on the seedlings.

[0008] According to the above configuration, a cultivation area for cultivating the seeds placed in the opening is formed around the opening and is positioned so as not to interfere with the cultivation areas of the seeds in other openings, so that the cultivation of the seeds planted in the opening is not hindered by the other seeds. In addition, the growth regions of adjacent openings are arranged so as to be in contact with each other, and the openings are arranged in multiple rows, with the openings in each row being arranged alternately with the openings in the adjacent rows, and within the area formed by the first row group of openings and the third row group of openings, a second row group of openings is arranged alternately with these. That is, a second row of openings is arranged in a staggered manner (e.g., staggered) 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 regions are in contact with each other.

[0009] Therefore, the openings can be arranged more efficiently than before within the same area as before, while ensuring a growing area for each opening without being affected by other seeds and seedlings. For example, whereas five openings are arranged in parallel in one row as in the conventional method, with the above-mentioned configuration, it is possible to arrange five openings in a width of three rows. Therefore, the area of ​​the fixing parts (hem parts, etc.) of the seed sheet can be increased, and the seed sheet can be positioned in a taut state on ridges, etc., so that the openings can be appropriately positioned in relation to the ridges and the seeds can be grown effectively.

[0010] Furthermore, according to the above configuration, the distance between the openings in the column direction is longer than the distance between the openings in the first column and the third column. The growth region of the openings in the first row (Z1, etc.), the growth region of the openings in the second row (W1, etc.), and the growth region of the openings in the third row (U1, etc.) are arranged so as to be in contact with each other. As a result, the distance between rows (first to third rows, etc.) can be shortened, and the seedling sheet can have the same number of openings within the same area as before, making the seedling sheet easier for users to use.

[0011] Preferably, the openings in the seed sheet are formed by cutting perforations. The perforations are formed by alternately arranging small hole portions and connecting portions, and arc-shaped removal assisting portions larger than the small hole portions are formed on the outside of the two small hole portions and the connecting portion. It is characterized by the fact that

[0012] According to this configuration, the opening can be easily formed by cutting the perforation. Also, According to the above configuration, by forming a removal auxiliary part such as a slit in addition to the perforations, even when the user cannot visually identify the position using the perforations alone, the removal auxiliary part has the effect of acting as a "marker," making it possible to visually identify the position. In addition, the "removal aid" makes it easier to cut the "perforations."

[0013] Preferably, the seed sheet is a sheet for home vegetable gardening, the short sides are configured to be 950 mm to 1350 mm, the long sides are configured to be 50 mm, the diameters of the openings and the growing areas are configured to be 60 mm and 75 mm, respectively, along the short side direction, the odd numbered rows having three openings and growing areas and the even numbered rows having two openings and growing areas are provided, the bottom parts are formed at both ends of the short sides as areas where the openings and the growing areas are not formed, and the bottom parts occupy 37.8% to 38.9% of the width of the short sides. It is characterized by the fact that Effect of the Invention

[0023] As described above, the present invention has the advantage of providing a seed sheet, a seed sheet manufacturing apparatus, a seed sheet manufacturing method, and a seed sheet manufacturing program that do not reduce the number of openings in the short side direction of a standard seed sheet that is a standard size on the market, while appropriately securing the bottom area.

[Figure 8] 6 is a schematic explanatory diagram showing the arrangement of the cutting edge of the perforation blade portion 120 and the cutting edge of the slit blade portion 130 in FIG. 5. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are imposed thereon. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is limited thereto.

[0026] (Main components of home garden sheet 1) FIG. 1 is a schematic diagram showing a "home vegetable garden sheet 1" which is an example of a seedling sheet according to the present embodiment. As shown in FIG. 1, the vegetable garden sheet 1 is, for example, a strip-shaped sheet made of polyethylene with short sides 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 home garden sheet 1 is the size that is most in demand on the market, and this size is the standard size for home garden sheets 1. The sheet 1 also has a number of openings X-U etc. that enable a user to place the sheet 1 on a "ridge," which is an example of a location for arranging vegetables in a home garden, etc., and plant seedlings of plants such as carrots and onions at appropriate intervals.

[0028] (Main configuration of opening X, etc.) FIG. 2 is a schematic enlarged view of the opening Z in FIG. As shown in Figure 2, the outline of the opening Z of the sheet 1 is formed by a perforation P, and when the user uses the sheet (for example, after laying it out taut on a ridge in a home vegetable garden), he or she can easily remove the portion of the sheet covering the opening Z (the inside of the perforation P) by pressing the perforation P or its vicinity with the user's finger.

[0029] As shown in FIG. 2, the perforation P has "small hole portions P1" and "connecting portions P2" arranged alternately, and the "small hole portions P1" are formed in an oval shape. The long side of the "small hole portion P1" of this perforation P is, for example, 3 mm, and the short side is, for example, 1 mm. Moreover, the longitudinal length of the "connecting portion P2" of the perforation P is 0.6 mm to 0.8 mm. By forming a perforation P having small hole portions P1 and connecting portions P2 in such numerical ranges in the sheet 1, the user can easily remove the sheet within the perforation P.

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

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

[0032] In addition, by forming the slits S, even when the user cannot visually identify the position of the perforations P by themselves, the slits S have the effect of providing a "marker" that allows the user to visually identify the position. 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 bottom part 1d, etc.) As shown in FIG. 1, the openings X etc. are arranged in a "staggered (eg, zigzag)" manner. As shown in FIG. 1, the sheet 1 has "hems 1d, 1e" which are an example of a fixing portion formed at both ends (left and right ends) in the direction of long sides 1b, 1c. The width of the bottom portions 1e and 1d is, for example, about 185 mm each, and the sum of the lengths of both sides is 370 mm, which is 38.9% of the width of the short side 1a of the sheet 1, which is 950 mm.

[0034] Therefore, by placing field soil on the bottom parts 1d and 1e, the sheet 1 can be placed in a taut state so as to cover the "ridges." Since the openings X and the like are appropriately positioned at predetermined positions, the user can plant the seedlings in appropriate positions.

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

[0036] In the case of a home garden sheet 1 with a short side 1000a of 950 mm, a sheet 1000 having five openings 1001a etc. arranged along the short side 1000a is in the highest demand and has become the standard. If five openings 1001a, etc. are arranged in parallel on the sheet 1000, as shown in Figure 3, the length of the bottom edges 1000d, 1000e on both sides will be a total of 290 mm, which is only about 30.5% of the width of the sheet 1000, which is 950 mm.

[0037] Even if soil is placed on the bottom portions 1000d, 1000e of such a sheet 1000, the bottom portions 1000d etc. do not function adequately as fixing portions, and the sheet 1000 cannot be sufficiently stretched over the ridges. As a result, there is a problem in that the openings 1001a etc. cannot be properly positioned over the ridges.

[0038] In this regard, in the present embodiment, the proportion of the hem portion 1d etc. shown in FIG. 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 portion is significantly improved.

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

[0040] (1st column) Specifically, as shown in FIG. 1, three openings X, Y, and Z are arranged along the short side 1a of the sheet 1, each of which is spaced apart, for example, by 260 mm, to form a first row (an example of a group of openings in the first row). Around the openings X, Y, and Z, there are formed growing areas X1, Y1, and Z1 for the seedlings planted in the openings X and the like (indicated by dashed lines in the drawing).

[0041] The cultivation area X1 etc. is a unique area in which each seedling can grow without substantial interference with other adjacent seedlings. The growth regions X1, Y1, and Z1 are regions having a radius of, for example, 75 mm from the center of the opening X, etc.

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

[0043] The openings V and openings W that form the second row also have growth regions V1 and W1 (dashed line portions) respectively, and growth region V1 etc. are arranged so as to be in contact with growth regions X1 and Y1 of the first row, and growth region W1 is arranged so as to be in contact with growth regions Y1 and Z1 of the first row.

[0044] (3rd column) Below the second row, as shown in FIG. 1, an opening S is disposed diagonally below the opening V, and an opening T is formed diagonally below the openings V and W. In addition, an opening U is formed diagonally below opening W, and openings S, T, and U form a third row (third row group of openings), with the spacing between each being 260 mm.

[0045] Growth regions S1, T1, and U1 are also formed in the openings S, T, and U forming these three rows, respectively. The growth regions S1, T1, and U1 are in contact with the growth regions X1 and the like in the first and second rows, respectively. Specifically, the growth region S1 contacts the growth region X1 in the first row and the growth region V1 in the second row, and the growth region T1 contacts the growth region Y1 in the first row and the growth regions V1 and W1 in the second row. Furthermore, the growth region U1 is in contact with the first row growth region Z1 and the second row growth region W1.

[0046] (Relationship between columns 1 to 3, etc.) In this manner, in this embodiment, the first row growth regions X1, etc., the second row growth regions V1, etc., and the third row growth regions S1, etc. are in contact with adjacent growth regions X1, etc. In other words, the growth regions X1, etc. in the first, second and third rows are disposed so as to be in contact with the growth regions X1, etc. in the other two rows, respectively. Therefore, the growth regions X1, Y1, and Z1 in the first row are in contact with the growth regions S1, T1, and U1 in the third row, respectively.

[0047] The distance (260 mm) between the openings X in the same row is longer than the distance between the openings Z, U in the first and third rows that are between different rows. Specifically, the distance between the 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 length between the openings Z, Y, etc. in the same row (first row, etc.) is longer than this length (260 mm).

[0048] Although not shown in FIG. 1 etc., the fourth row and subsequent rows are formed on the sheet 1 in the same manner as the first to third rows. In this embodiment, as described above, the growth regions X1, etc. of the openings X, etc. in the first to third rows are configured to be in contact with each other. For this reason, for example, the distance from the center of each of the openings Z to the growth region Z1 of the opening Z, the growth region U1 of the opening U, and the growth region W1 of the opening W in FIG. 1 are all 150 mm, and are the same length.

[0049] By arranging in this manner, even if the openings X, etc. are arranged in a staggered manner (alternately) as shown in FIG. 1, it is possible to ensure the growth regions X1, etc. of all the openings X, etc. without interfering with other growth regions X1, etc.

[0050] (Configuration of openings 1001a, etc. of a conventional vegetable garden sheet 1000) As shown in FIG. 3, in the conventional seed sheet 1000, five openings 1001a, etc. are arranged in a row along the short side 1000a direction, and each row is similarly arranged, so that the openings 1001a, etc. are arranged in a checkerboard pattern.

[0051] A standard seed sheet 1000 often has five openings 1001a etc. arranged along the short side 1000a, and as customers also request this configuration, there was no choice but to arrange five openings along the short side 1000a. For this reason, as described above, the area of ​​the "hem portions 1000d, 1000e" on both sides arranged along the long sides 1000c, 1000d of the sheet 1000 is narrow, and as shown in Figure 3, when the short side 1000a is the standard 950 mm, the hems 1000d, 1000e on both sides can only be secured at 145 mm each, so that even if soil is placed on the hems 1000d etc., the fixing function of the sheet 1000 is not fully exerted.

[0052] In this regard, in the present embodiment, as described above, only three or two openings X are arranged, for example, so that a sufficient "hem portion 1d, 1e" can be secured and the fixing function can be fully exerted (FIG. 1).

[0053] On the other hand, in this embodiment, since only three or two openings X, etc. are arranged in one row of the sheet 1, the number of openings X, etc. appears to be reduced compared to the case where there are five openings X, etc. in one row of the conventional example of the sheet 1000 in FIG. 3. However, as shown in FIG. 3, in the conventional sheet 1000, when the gap between the openings 1001a, etc. is taken into consideration for the growth areas as described above, a gap of, for example, 150 mm is absolutely necessary.

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

[0055] Even with this arrangement, as described above, the growth regions X1, etc. of the openings X, etc. are secured, and they do not interfere with each other. In addition, in this embodiment, by arranging the openings X, etc. as shown in FIG. 1, it is possible to arrange five openings X, etc., similar to those in the conventional method, within the length between the conventional 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 home garden sheet 1 can have the same number of openings X, etc. within the same area (between the first and second rows) as in the conventional home garden sheet 1, making the home garden sheet 1 easy for users to use.

[0056] In this embodiment, for convenience of explanation, in FIG. 1 and the like, the three openings X, Y, and Z are referred to as the first row, the two openings V and W are referred to as the second row, and the three openings S, T, and U are referred to as the third row. However, as described above, the five openings X etc. combining the first and second rows correspond to the conventional row in FIG. 3 (the five openings 1001a, 1001b, 1001c, 1001e). For this reason, in actual transactions involving the seed sheet 1, the first and second rows in this embodiment are collectively referred to as the "first row," and the third row and the fourth row below it are collectively referred to as the "second row." In this case, as shown in FIG. 1, the distances between the five openings X, V, Y, W, and Z are all 130 mm.

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

[0058] As shown in FIG. 4(a), by disposing the opening W at the midpoint between the openings Y and Z, the length of b in FIG. 4(b) becomes 130 mm. Furthermore, by arranging the growth regions Z1 of the openings Z, U, and W so that they are in contact with each other, the distance (L) between the openings W and Z also becomes "150 mm".

[0059] FIG. 5 is a schematic explanatory diagram showing a seedling sheet 50 which is another example of a seedling sheet having the same standard dimensions as the seedling sheet 1 according to the present embodiment. A seedling sheet 51 shown in FIG. 5 has many components in common with the above-mentioned seedling sheet 1, so a description of the common parts will be omitted and the differences will be mainly described. The seedling sheet 50 is formed such that the short side 51a is longer than the short side of the seedling sheet 1, which is 950 mm, at 1350 mm. Therefore, the seat 1 has four openings X, Y, Z, R, which is more than the three openings X, Y, Z in the first row of the seat 1.

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

[0061] The bottoms 51d and 51e of the sheet 50 are each 255mm, which add up to 510mm, or 37.8% of the 1350mm short side of the sheet 50. By placing soil or the like on the bottoms 51d and 51e, the sheet 50 can be placed taut to cover the ridges, just like the sheet 1 described above. In other words, the bottoms 51d and the like effectively function as fixing parts.

[0062] As described above, the seedling sheet 50 shown in FIG. 5 has the same functions and effects as the seedling sheet 1 described above, except for the length of the short sides 51a and the number of openings X. Also, similar to the above-mentioned Sheet 1, when trading seed sheet 50, the first and second rows are collectively referred to as the "first row," and the third row and the fourth row below it are collectively referred to as the "second row." In this case, as shown in FIG. 5, the distances between the seven openings X, V, Y, W, Z, Q, and R are all 130 mm.

[0063] (Configuration of the home garden sheet manufacturing device 100) FIG. 6 is a schematic diagram showing the main configuration of a "home vegetable garden sheet manufacturing apparatus 100" which is an example of a seedling sheet manufacturing apparatus. As shown in Figure 6, the home garden sheet manufacturing apparatus 100 has a cylinder portion 110, a perforation blade portion 120 for forming perforations P in the home garden sheet 1, and a blade holding portion 111 for holding the perforation blade portion 120.

[0064] The blade holding portion 111 of the manufacturing apparatus 100 is configured to hold the perforation blade portion 120 and also to be able to detachably hold a "slit blade portion 130," which is an example of a blade portion for forming a removal assist portion. Specifically, the slit blade portion 130 is fixed to the blade portion holding portion 111 by a "slit blade holding portion 140," which is an example of a protrusion position adjustment portion.

[0065] In addition, the slit blade holding portion 140 is configured so that the protruding position of the slit blade portion 130 relative to the home garden sheet 1 can be adjusted to any position by using a screw or the like (arrow h in FIG. 6).

[0066] FIG. 7 is a schematic explanatory diagram relating to the protruding position of the slit blade portion 130. As shown in FIG. As shown in FIG. 6, when the cutting edge of the slit blade portion 130 has an obtuse angle, the length l1 of the cutting edge is short, as in the slit blade portion 131 of FIG. 7, whereas when the cutting edge has an acute angle, the length l2 of the cutting edge is long, as in the slit blade portion 132 of FIG. 7. In this way, the protruding position of the blade tip of the slit blade portion 130 varies depending on the type of the blade tip.

[0067] Therefore, in this embodiment, the slit blade holding part 140 adjusts the protruding position of the slit blade part 130 depending on whether the blade tip is obtuse or acute, and can be adjusted to be the same as the perforation blade part 120. This is a highly efficient configuration (arrow h in Figure 6).

[0068] In this regard, in the conventional configuration, when the cutting edge of the slit blade portion 130 is changed, the protruding position of the slit blade portion 130 is changed, and therefore, it is necessary to adjust the protruding position of the perforation blade portion 120 in the same manner. However, in this embodiment, it is sufficient to adjust only the slit blade portion 130, and the blade tip can be easily adjusted.

[0069] Incidentally, as shown in FIG. 6, the blade of the perforation blade portion 120 is 3 mm, and the spacing between the blades of the perforation P is 0.6 to 0.8 mm. For this reason, as shown in Figure 2, the small hole portion P1 of the perforation P is formed to be 3 mm and the connecting portion 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 leaving the perforation P uncut when there is no need to cut it.

[0070] FIG. 8 is a schematic explanatory diagram showing the arrangement of the cutting edge of the perforation blade portion 120 and the cutting edge of the slit blade portion 13 in FIG. As shown in FIG. 8, the cutting edge of the perforation blade portion 120 and the cutting edge portion of the slit blade portion 13 in FIG. 6 are arranged such that their tips, for example, the cutting edges, overlap each other. Therefore, as shown in FIG. 2, the perforations P and the slits S can be formed closely to each other with high accuracy.

[0071] Unlike this embodiment, if the perforation blade portion 120 and the slit blade portion 130 are arranged so as to be in closer contact with each other, a slit S can be formed on the perforation P. As shown in FIG. 6, the home garden sheet manufacturing apparatus 100 has around six "home garden sheets 1" that form perforations P and slits S arranged thereon, and also has a "receiving table 150" which is an example of a receiving portion that receives the perforation blade portion 120 and the slit blade portion 130.

[0072] As shown in FIG. 6, the receiving base 150 has a blade receiving groove 151 which is an example of a storage portion. Therefore, when a home garden sheet 1 is placed on the device 100 in Figure 6 and the cylinder portion 110 is lowered downward from the top of Figure 6 in this state, the perforation blade portion 120 and the slit blade portion 130 come into contact with the sheet 1, forming perforations P and slits S, and are accommodated in the blade receiving groove 151 located below.

[0073] With this configuration, the perforation blade portion 120 and the slit blade portion 130 can be prevented from colliding with the receiving base 150, and deterioration of the receiving base 150 can be prevented. Furthermore, compared to the conventional case in which the perforation blade portion abuts against a receiving base to form perforations P in the sheet 1, in the present embodiment in which the perforation blade portion 120 and the slit blade portion 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 the home garden sheet manufacturing apparatus 100 in this manner, the perforations P and slits S shown in FIG. 1 and the like can be formed in the home garden sheet 1 with high precision.

[0075] In the present embodiment, the home garden sheet manufacturing apparatus 100 may be configured to include a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk, and the like, which are connected via a bus. In this case, the perforations P and slits S are formed in the home garden sheet 1 in response to instructions from a computer.

[0076] In the above-described embodiment, an example has been given in which the invention is realized as an apparatus, but the invention is not limited to this, and the invention may be distributed as a program that can be executed by a computer, stored on a storage medium such as a magnetic disk (e.g., a floppy (registered trademark) disk, a hard disk, etc.), an optical disk (e.g., a CD-ROM, a DVD), a magneto-optical disk (MO), or a semiconductor memory.

[0077] The storage medium may be any medium that can store a program and is computer readable. The storage format of the storage medium is not particularly limited.

[0078] In addition, an OS (operating system), database management software, network software, or other MW (middleware) running on a computer may execute some of the processes for realizing this embodiment based on instructions from a program installed on the computer from a storage medium.

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

[0080] Furthermore, the computer in the present 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, etc., or a system in which multiple devices are connected to a network.

[0081] In addition, the computer in this invention is not limited to a personal computer, but also includes an arithmetic processing device, a microcomputer, etc. included in information processing equipment, and is a general term for equipment or devices that can realize the functions of the present invention by a program.

[0082] The above describes the embodiments of the present invention. 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 arbitrarily combined in a manner different from the above. [Explanation of symbols]
