Description

  The present invention relates to a size allocation apparatus for tatami mats, and more specifically, room dimension data measured using a dimension measuring instrument, tatami laying patterns suitable for the dimension data are allocated, and the standard dimensions of the allocated tatami mats and the The present invention relates to a tatami mat size assigning apparatus that adjusts tatami mat dimensions by comparing room dimension data.

Conventionally, in the tatami mat industry, a unit of sizing basket has been used as a length unit from the measurement of tatami mats to the production of tatami mats, and a sizing basket has been used as a length unit in automated tatami mat machines.
Naturally, the length and the habit value measured in Patent Document 1 are also in units of size. However, in recent years, the number of tatami craftsmen has decreased, and on the other hand, the number of amateurs making tatami mats at home centers and the like has increased.

  In addition to the standard tatami mats such as 58, 36 and Honma from ancient times in Japan, the size of tatami mats is 1 meter x 2 meter standard tatami mats and small tatami mats laid out in the ocean Tatami) is also increasing.

  Due to the diversification of these needs, there has been a desire to use millimeter units as the length unit from measuring to tatami mat manufacturing. In addition, there has been a need to use a conventional unit of metric parts and millimeters. The reason for this is that you want to use different units according to the order status, such as whether the tatami you are going to make is a traditional tatami mat, such as Sanroku or Honma, or a new tatami mat (metric tatami mat). This is because there is a request. A tatami size allocation system that can achieve this has not yet been put into practical use.

  Therefore, a tatami store that has received an order from a construction store in millimeter units manufactures tatami mats by converting dimensional data into 厘 units. Also, if a new person joins the tatami store and doesn't know the shankuki method, then it is necessary to explain the shankuki method, and it will take time to become full.

A conventional tatami mat size assigning apparatus will be described below with reference to FIG.
FIG. 10 shows a state where an eight-tatami Japanese-style room is measured with a dimension measuring instrument. The dimension measuring instrument described in Japanese Patent No. 2684139 (Patent Document 1) developed by our company is used.

  Place a measuring instrument almost in the middle of the room, enter the site information of this room and the size standards of the tatami mats to be installed, “Goha”, “Sanroku”, “Honma” Then, the probe 13a is sequentially applied to the length data and the angle data for each measurement point. A mark is a measurement point, and a deviation value calculated from length data and angle data is stored for each measurement point.

As described in the specification of Japanese Patent No. 2684139, the deviation value is obtained by reading the dimension data of each room from the dimension measuring device, referring to the laying pattern for the read dimension data of the room, and making the size almost equal. For tatami mats that are allocated by proportionally allocating or by allocating multiple tatami mats by pillar-based allocating based on pillars, and for tatami mats that touch the sill, calculate the deviation of the lower and front tatami mats, and the tatami floor of the standard dimensions along with the tatami number Is obtained as deviation data by assigning a tatami number to each tatami floor.
For example, as shown in FIG. 11, the tatami floor of the rectangle ABCD composed of the upper front (AD), the lower front (BC), the left stile (AB), and the right stile (CD) indicated by dotted lines is used as a reference. When the other three sides touch the sill, the deviations Xa, Xb, Xc, Xd in the length direction of the points Aa, Ba, Ca, Da corresponding to the sill are measured, respectively, and further, the lower end B Then, the width-direction deviations Yb, Ye, and Yc at the center E and the other end C are measured, and a tatami floor indicated by solid lines Aa, Ba, Ea, Ca, and Da is designed. When the left and right stiles touch other tatami mats, the deviations Xa, Xb and Xc, Xd are set to zero. The deviation measured by the above method is a habit value.

Explanatory drawing of the deviation of a measurement point.

Embodiments of the present invention will be described below.
1 to 4 will be described in detail.
Fig. 1 shows the coordinates of each measurement point of the tatami in millimeters as the distance (absolute value) from the center of the dimension measuring device developed by our company that irradiates light in four directions at right angles. The circle mark indicates the starting point for measuring the dimension, and the numerical value indicates the length from the starting point to the tip of the arrow in mm.
For example. 1757.5 indicates the length from the starting point of 3 to the tip of the arrow 1 and 878.5 indicates the length from the starting point of 14 to the tip of the arrow 1.

FIG. 2 is a diagram in which measurement points measured by a room size measuring instrument are represented by XY coordinates.
As described in paragraphs [0018] to [0022] of the above-mentioned Japanese Patent No. 2684139, the measurement of the dimensions of the room is performed by converting data obtained in polar coordinates from the length and angle to the measurement point of the room into an orthogonal coordinate system. Dimension data is calculated.

In the upper left of FIG. ▲ is a measurement point.
The position represented by coordinates 0.0 and 0.0 in the upper left of the figure is the origin (dimension reference (measurement point 1)). Draw a dotted line (referred to as the upper virtual line) to the right from the origin 0.0, and set the line extending on the upper virtual line as the X axis, and the dotted line downward from the origin 0.0 (referred to as the left virtual line) And the line extending on the left-side virtual straight line is defined as the Y-axis. The numbers on the upper side are numerical values on the X and Y coordinates (X and Y coordinates). The same applies to the bottom, left, and right sides.

  2 will be described in more detail. For example, the numerical value displayed in FIG. 2 indicates deviation data in the X or Y axis direction of each measurement point 1 to 14, and the number indicated on the upper side, the Y coordinate at the measurement point 2 -1.5 indicates that it is 1.5 mm inside from the upper virtual line. In addition, the Y coordinate of 0.0 at the measurement point 3 indicates that it exists on the upper virtual line, and the +1.5 of the Y coordinate at the measurement point 4 exists 1.5 mm outside the upper virtual line. Is shown.

  Similarly, for example, +1.5 of the X coordinate at the measurement point 14 on the left side indicates that the left side is 1.5 mm outside the virtual straight line on the left side. The measurement point 13 is the same.

Further, for example, the X coordinate 3518.0 at the measurement point 5 on the right side indicates a distance of 3518.0 mm in the horizontal direction from 0.0 (measurement point 1), and the measurement point 7 is the same.
For example, the Y coordinate 2637.5 at the measurement point 8 on the bottom side indicates that the distance is 2637.5 mm in the vertical direction from 0.0 (measurement point 1), and the measurement point 9 is the same.

  In the present invention, the dimensions of the room converted into XY coordinates are represented by the deviation from the upper virtual line for the upper side, the deviation from the virtual virtual line for the left side, the distance from the virtual virtual line for the right side, and the bottom side. Is expressed by the distance from the upper virtual line.

  FIG. 3 is a diagram for explaining the concept of the equally divided calculation method, in which the lengths of the room in the vertical direction and the horizontal direction are adjusted to be equal for each tatami mat. The sill of the room where the tatami is laid has a bend rather than the standard dimension, so the size of the tatami is adjusted to match the bend and the actual size of the room. FIG. 3 illustrates a case of a 6-tatami room, and three short sides of the tatami are laid down in the vertical direction of the room. In the horizontal direction, four short sides of the tatami are laid, but the vertical direction shown in FIG. 3 is the portion I, and the horizontal direction is the portion II, and the dimensions of the short or long sides of the tatami are uniform. If it is, the aesthetics are good when tatami is laid, and the tatami is often laid with the dimensions calculated in this way. As dimension allocation calculation methods other than equal division, there are known width equalization, entry criteria, column criteria, and the like, but explanations thereof will be omitted.

  4 is an explanatory diagram in which a room of 6 tatami mats is divided equally, FIG. 4 (a) is the dimension data of the room, and FIG. 4 (b) is the length of each of the tatami mats (1) to (6) in the short side direction. The length dimension and the length dimension in the long side direction are shown.

A method for equally dividing a 6-tatami room will be described with reference to FIGS.
In FIG. 4A, H is a value obtained by measuring a dimension at each of the measurement points 1 to 14 shown in FIG.
The dimension data H is measured by obtaining a measurement dimension on the XY coordinates with the measurement point 1 as the origin at each measurement point.

  Since there are no standard dimensions such as 58 and Honma in millimeter units, the coordinate distance between two points is measured as the room dimension. That is, H1 to H14 have the X coordinate and Y coordinate of measurement point 1 in FIG. 2 as H1 (origin), the Y coordinate of measurement point 2 is H2, the Y coordinate of measurement point 3 is H3, and the Y coordinate of measurement point 4 is Is H4, and the X and Y coordinates of the measurement point 5 are H5. Therefore, at the measurement point corresponding to the corner of the room as in H1 above, the two data of the X coordinate and the Y coordinate are used properly depending on the direction. X coordinate of measurement point 6 is H6, X coordinate of measurement point 7 is H7, X coordinate and Y coordinate of measurement point 8 are H8, Y coordinate of measurement point 9 is H9, Y coordinate of measurement point 10 is H10, Measurement point The Y coordinate of 11 is H11, and the X and Y coordinates of the measurement point 12 are H12. The X coordinate of the measurement point 13 is H13, and the X coordinate of the measurement point 14 is H14.

  In FIG. 4B, W indicates allocation data, and W is a value calculated using the equal allocation calculation method of FIG. W1 to W15 are the lengths of the short sides of each tatami, and Wt1 to Wt10 are the lengths of the long sides of each tatami.

Equal allocation is a vertical line that hangs down from the front passing through the measurement reference point by obtaining allocation data for each tatami mat whose size is predetermined based on the dimension data of the room and dimension data H1 to H14 measured in advance. And dividing the line segment to the bottom by the number of tatami mats laid there.
FIG. 4C shows the actual size value of the allocation data.
The deviation data S shown in FIG. 4 (d) has the measurement point 1 as the origin, the upper side is the deviation in the Y-axis direction from the X-axis, and the lower side is the reference length x the number of short sides of the tatami mat laid from the X-axis ( (Varies depending on the number of tatami mats in the room) as the standard dimension, the difference from the standard dimension as the deviation, the left side as the deviation in the X-axis direction from the Y axis, and the right side as the standard length of the short side of the tatami mat laid from the Y axis The size x number of sheets is set as a reference dimension, and a difference from the reference dimension is set as a deviation.

  The measurement reference point is a point located inside the room on the upper side of the tatami laid in a direction transverse to the room. A person who uses a measuring scale is installed by installing a device that irradiates a laser beam on the cross. This is the point where the cross points are aligned. When measurement is performed using the dimension measuring instrument described in Patent Document 1, the dimension measuring instrument is installed in the center of the room for measurement, and no measurement reference point is used. However, when calculating the even division, the allocation data is first obtained from the measurement points on the measurement reference point. For example, in the case of 3 tatami mats, the upper front corner of the tatami laid in the horizontal direction and the vertical In the case of 6 tatami mats, the point where the upper front corners of two tatami mats laid in the horizontal direction are the measurement reference points.

  In the following description, the lower front refers to the side where the long side of the tatami is in contact with the sill, and the upper front refers to the side where the long side of the tatami is in contact with the tatami.

  In this description, as described above, it is assumed that room dimension data is acquired using the dimension measuring instrument described in Japanese Patent No. 2684139 already filed by the present applicant. By using the dimension measuring device, the measurement data of FIG. 4A can be easily obtained, and the measurement method is described in paragraphs [0028] to [0031] of the patent publication.

Next, a method for equally dividing calculation using a heel unit will be described with reference to FIG.
The procedure for obtaining the dimension of the short side of the tatami mat by the length in the Y-axis direction of the line segment passing through the measurement reference point will be described. In the case of a 6 tatami room, the measurement reference point is the position of Δ in FIG. In the equal division, the dimensions of the three tatami mats (1), (3), and (4) are allocated so that the dimensions in the short side direction are the same. When allocating in this way, a method is adopted in which the room deviation data Hm and Hn are not used but the respective deviations are set to Sm and Sn, and equal division is performed from the deviation data. The allocation data equally divided by the room dimension data is data obtained by adding the magnitude of the deviation to the reference dimension.

  The sum of the short side dimensions of tatami mats (1), (3), and (4) is obtained by the following formula: standard dimension x 3 sheets + tatami mat (1) deviation + tatami mat (3) deviation + tatami mat (4) deviation formula Divide evenly to find the dimensions of the tatami mat.

The size of the tatami obtained by dividing equally and finding the deviation is the same. Since there are three tatami mats (1), (3), and (4) in the vertical direction, the dimension Wn in the width direction of the tatami mat is the lower side corresponding to the deviation data Sm on the upper side and the dimension data on the upper side in the vertical direction. The dimension data Sn is added, and the number t in the width direction existing between Sm and Sn is calculated by the following equation [1].
Deviation of Wn = (Sm + Sn) / t ... [1]
At this time, Sm and Sn used for the calculation are deviations from the standard size of the tatami, and the first decimal place of Wn is rounded down. Deviation of Wn = K.

Next, a specific calculation method in the case of 6 tatami mats will be described. First, a procedure for obtaining W3 by the above calculation and obtaining W6 and W7 using W3 will be described. The short side length W3 of the upper tatami mat (1) shown in Fig. 4 (b), the short side length W6 of the middle tatami mat (3), and the short side length W7 of the lower tatami mat (4). Since the upper front measurement point H3 shown in FIG. 4 (a) is 0, the bottom measurement point H10 = 10, and the number of tatami mats to be laid is 3, the length of the short side of the upper tatami (1) W3
Deviation of W3 = (0 + 10) / 3
= 3.333
Truncate after decimal point
≒ 3
It becomes. For example, in the case of a 58 tatami mat with a short side reference dimension of 2 9 inches, W3 is 2 9 inches 3 inches. Expressed as deviation from the reference dimension.

After obtaining W3, the allocation data is calculated in order from top to bottom. When the line from the bottom to the bottom and the base line is subtracted by W3 obtained above and divided by the number of tatami mats, the deviation of the short side length W6 of the middle tatami (3) is
Deviation of W6 = (deviation of S3 + S10−W3) / 2 = (0 + 10-3) / 2
= 3.5
It becomes. Truncate after decimal point
≒ 3
It becomes. W6 becomes 2 scales, 9 dimensions and 3 inches when the deviation of 3 inches is added to the standard dimension (2900).
The length W7 of the short side of the lower tatami (4) can be obtained by subtracting the perpendicular line and the line segment from the bottom front to the bottom side with W3 and W6 obtained above.
Deviation of W7 = (0 + 10)-(3 + 3)
= 4
It becomes.

  For W7, when the deviation of 4mm is added to the standard dimension, it becomes 2x9x4cm. The widths of the three tatami mats are W3, W6, W7, 2 scale 9 inch 3mm, 2 scale 9 inch 3mm, 2 scale 9 inch 4mm, and they are almost uniform with a difference of 1mm.

On the other hand, the conventional calculation method based on the shankuki method is converted into numbers in millimeters and calculated as follows. That is, in the example of 6 tatami mats shown in FIG. 2, the measurement point H3 before the upper side is H3 = 0, the measurement point H10 is 2639.0 on the bottom side, and it is divided by 3 of the number of tatami mats to lay.
W3 = (0 + 2639.0) / 3
= 879.666. Rounded down decimals ≒ 879.0
It becomes. W3 is 879.0 mm.
After calculating W3, the allocation data is calculated in order from top to bottom, and the vertical line and the line segment from the bottom to the bottom are subtracted by W3 calculated above and divided by the number of tatami mats 2 and the middle. The short side length W6 of the tatami mat (3) is
W6 = (0 + 2639.0-879.0) / 2
= 880.0
It becomes. W6 is 880.0 mm.
The length W7 of the short side of the lower tatami (4) can be obtained by subtracting the perpendicular line and the line segment from the bottom front to the bottom side with W3 and W6 obtained above.
W7 = (0 + 2639.0) − (879.0 + 880.0)
= 880.0
It becomes. Comparing the width of three tatami mats, there is a difference of 1.0mm between W3 and W7, which is not even.

  Since the length W3 of the short side of the upper tatami mat (1) shown in FIG. 4 (b) is obtained by the above equation [1], the next method for calculating W1 of the tatami mat (1) and other W is as follows. explain. Since the upper front side where the tatami mat (1) touches the tatami mat (3) and the tatami mat (5) is a straight line, the length of W1 is the length from the point where the perpendicular drawn from W3 to W1 intersects to the point where it touches the sill.

  Since the deviation of the Y-axis coordinates of H1 and H3 is zero, the lengths of W1 and W3 are the same. The length of the short side is to obtain the length from top to bottom for each measurement point, but it is the same even if the length is calculated by comparing the difference in deviation for each measurement point.

Using W3 obtained by the above method, the deviation of the short side lengths W1, W2, W4, W5 in the tatami mats (1), (2), that is, the deviation of the tatami mat located on the upper side of the room is obtained. When W1 to W5 are located on the upper side and W3 is obtained, W1, W2, W4, and W5 are obtained by comparing deviation values with W3. The calculation for determining the allocation data based on the difference in the upper side deviation is expressed by an expression in which the allocation data Wj is added to the difference between the upper side deviation data Sj and the deviation data Si,
Wi = Si-Sj + Wj ・ ・ ・ [2]
It becomes.
Since the calculation result is the same whether the deviation value includes the reference dimension or only the deviation value, W1, W2, W4, and W5 are calculated using Equation [2].
W1 deviation = S1 Y deviation-S3 + W3 deviation = 0-0 + 3 = 3
W2 deviation = S2 -S3 + W3 deviation = -5-0 +3 = -2
Deviation of W4 = S4 -S3 + W3 deviation = 5-0 + 3 = 8
W5 deviation = S5 Y deviation-S3 + W3 deviation = 0-0 +3 = 3
It becomes.

Next, W7 is obtained by the same calculation method as described above, and the short side lengths W8 and W9 of the tatami (4) on the lower side of the room are obtained using W7. When W8 and W9 are located on the bottom side and W7 is obtained, W8 and W9 are obtained by comparing deviation values with W7. Since the calculation result is the same whether the deviation value includes the reference dimension or only the deviation value, the calculation is performed using Equation [2].
Deviation of W8 = S11-S10 + W7 deviation = 10-10 + 4 = 4
Deviation of W9 = S9 -S10 + W7 deviation = 5-10 + 4 = -1
It becomes.

Next, the long side lengths Wt8 and Wt9 in the tatami mats (5) and (6) are obtained using W6 and W8 and W9 obtained by the above calculation method. At the point where the long side tatami and the two short side tatamis contact each other like the measurement point 11, the long side assignment data Wti is the sum of the two short side assignment data Wi and Wj.
Wti = Wi + Wj [3]

Since the sum of the deviation of the long side of tatami (5) and the short side of tatami (3) and tatami (4) is the same at measurement point 11, express as Wt8 deviation = W6 deviation + W8 deviation. Can do.
The deviation of Wt8 = 3 + 4 = 7.
In addition, the sum of the deviations of the long side of the tatami mat (6) and the short side of the tatami mat (3) and the tatami mat (4) at the measurement point 9 is the same.
Deviation of Wt9 = deviation of W6 + deviation of W9 = 3-1 = 2.

Next, the long side lengths Wt7 and Wt10 in the tatami mats (5) and (6) are obtained using Wt8 and Wt9. Wt7 and Wt10 are calculated using Equation [2].
Wt7 deviation = S12 Y deviation-S11 + Wt8 deviation = 15-10 + 7 = 12
Wt10 deviation = S8 Y deviation-S9 + Wt9 deviation = 5-5 + 2 = 2
It becomes.

Next, a procedure for obtaining the dimension of the short side of the tatami by the length in the X-axis direction of the line passing through the measurement reference point will be described. Above, tatami (5) (6) short side dimension + tatami (4) long side dimension sum = short side standard dimension x 2 sheets + long side standard dimension x 1 sheet + tatami (5) The dimension of the short side of the tatami can be obtained from the equation of deviation + deviation of the tatami mat (6) + deviation of the tatami mat (4). The size of the tatami is the same by dividing equally and finding the deviation. The dimension Wtn in the width direction of the tatami is equivalent to the half tatami mat corresponding to the width direction existing between Sm and Sn by adding the deviation data Sn on the right side corresponding to the deviation data Sm on the left side and the dimension data on the right side in the horizontal direction. The number s to be calculated is calculated as in equation [4].
Deviation of Wtn = (Sm + Sn) / s ... [4]
In this case, Sm and Sn used for the calculation are calculated only by the deviation from the standard size of the tatami.
Round off the first decimal place of Wtn, Wtn deviation = K

Next, a procedure for obtaining W10 and obtaining W13 and Wt5 using W10 will be described. The length W10 of the short side of the tatami mat (5) shown in FIG. 4 (b), the length Wt5 of the long side of the tatami mat (3), the length W13 of the short side of the tatami mat (6), The measurement point H14 = 5 on the left side, the measurement point H6 = 15 on the right side, and the number of half tatami mats to be laid is 4, so the length W10 of the short side of the tatami mat (5) is
Deviation of W10 = (5 + 15) / 4
= 5.0
Truncate after decimal point
≒ 5
It becomes. For example, in the case of a tatami mat with a standard dimension of 58, W10 has a length of 2 9 inches and 5 inches, and is represented by a large or small deviation from the 2 dimensions 9 dimensions which is the reference dimension of the short side.

After obtaining W10, it calculates in the order of W13 and Wt5. The length W13 of the short side of the tatami mat (6) is obtained by subtracting the line passing through the measurement reference line in the horizontal direction by the W10 obtained above and dividing it by the number of tatami mats (3). The deviation of length W13 is
Deviation of W13 = (deviation of S6 + S14-W10) / 2 = (5 + 15-5) / 3
= 5.0
It becomes.
W13 is 2 scales, 9 dimensions and 5 inches when the deviation is added to the standard dimensions. The length Wt5 of the long side of the tatami mat (3) is obtained by subtracting the line segment passing through the measurement reference line in the horizontal direction by W10 and W13 obtained above. Deviation of Wt5 = (5 + 15)-(5 + 5)
= 10
It becomes.
Wt5 is 5 scales, 8 dimensions, and 1 minute when the deviation of 10 mm is added to the standard dimension (5800). The three tatami mats are W10, W13, Wt5, 2 scales, 9 dimensions, 5 inches, 2 dimensions, 9 dimensions, 5 dimensions, 5 dimensions, 8 dimensions, 1 minute (2 dimensions, 9 dimensions, 5 dimensions).

  The side where the tatami mat (3) and the tatami mat (4) are in contact is a straight line, and the corner is also a right angle, so that the deviation of Wt6 = deviation of Wt5 = 10.

Since the allocation data Wt2 is the value obtained by dividing the tatami mat (1) and the tatami mat (2) into two equal parts, the deviation of S14 = 5 and the deviation of S6 on the right side = 15 are divided by 2 tatami mats.
Deviation of Wt2 = (5 + 15) / 2 = 10

The allocation data Wt1 is obtained by calculation using the equation [2] from the previously obtained Wt2. Further, the allocation data W11 and W12 are obtained by calculation from the previously obtained W10.
Deviation of Wt1 = S1 -S14 + Wt2 = 0-5 + 10 = 5
Deviation of W11 = S13 -S14 + W10 = 10-5 + 10 = 15
W12 = Y deviation of S12-S14 + W10 deviation = 10-5 +10 = 15

  With respect to the allocation data Wt4, Wt3, W14, and W15, the allocation data can be obtained using the above method.

Next, an even division calculation method using millimeter units will be described.
Even when tatami mats are evenly allocated in millimeter units, they are calculated by the same calculation method as the method for equally dividing cocoon units. In that case, the timing at which the fraction processing with the first decimal place is performed is an important requirement for uniformly determining the width of the tatami mat.

  However, when calculating evenly in millimeters, the data is handled without providing standard tatami mat dimensions such as Gohachi and Saburoku as in the case of the Shakanuki method. , The data are not deviations but are calculated with the actual size data H.

  Hereinafter, the process of performing the even division calculation in millimeter units will be described with reference to FIG. First, the length component Hm in the Y-axis direction at the point on the upper side where the perpendicular in the Y-axis direction intersects the threshold from the measurement reference point, the length component Hn in the Y-axis direction on the lower side, t is the number of tatami mats, and an arbitrary constant c, where the value obtained by multiplying the allocation data by c is J, J is 1 in STP2) J = c (Hm + Hn) / t (5) The value of J is obtained by [5].

Next, the decimal part of J obtained by the above calculation in 2) is rounded down to obtain the integer part K of J. Next, in 3), by dividing K by c again, J / c≈K / c = Wn, that is, allocation data is obtained.
The reason why an arbitrary constant c of c is used as in 1) to 3) above is that when the allocation data is rounded down by a multiple of a certain decimal 1 / c, the allocation data is obtained by multiplying by the reciprocal c of the previous decimal. The value after the decimal point is incremented by one, c times, and the first decimal place is rounded down and divided by 1 / c, resulting in the same value as the allocated data rounded down by 1 / c. .

  When rounding down at a multiple of 1 / c, it is easy to cut down at 1 / c times by multiplying by c first. Even if c is a decimal, the same calculation result is obtained. For example, since a scale that can be read by a person using a scale is about 0.5 mm, a case where data is handled in units of 0.5 mm will be described. If the fraction of the allocation data of 0.6 or 0.7 exceeding 0.5 is rounded down to 0.5, the width of the tatami mat will be close.

  The above 1) is an arbitrary constant value obtained by adding the room dimension data at the point where the dimension data of the room at the lower front corner and the room dimension data at the lower front corner intersect with the base and dividing by the number of tatami mats. It is a thing multiplied. The above 2) is expressed as J = K + Δ using an integer K obtained by rounding down J to the first decimal place and a decimal point Δ.

Next, a procedure for calculating W3 in millimeter units and a procedure for obtaining W6 and W7 using W3 will be described. The short side length W3 of the upper tatami mat (1) shown in Fig. 4 (b), the short side length W6 of the middle tatami mat (3), and the short side length W7 of the lower tatami mat (4). 2, the length on the Y-axis of the measurement point H3 before and below the upper side shown in FIG. 4A from the length on the XY coordinates of each measurement point shown in FIG. The length of the measurement point H12 on the Y axis is 2639.0, and from the above equation [5], the short side length W3 of the upper tatami mat (1) is the number of tatami mats passing through the line segment of the room dimension data. Divide by 3, double by any constant,
J = 2 (0 + 2639.0) /3=1759.332.
J is divided into an integer and a decimal, and J = 1759 + 0.332.
W3 is divided by half of the reciprocal of the doubled number,
W3 = 1759/2
= 879.5.

W3 is 879.5 mm. After obtaining W3, the allocation data is calculated in order from top to bottom. The length W6 of the short side of the middle tatami (3) is drawn by dividing the room dimension data line by the length of W3 and dividing it by the number of tatami mats to pass through. Is doubled by an arbitrary constant,
J = 2 (0 + 2639.0-879.5) /2=1759.5, J is divided into an integer and decimal, J = 1759 + 0.5, and divided by an arbitrary constant c = 2 obtained by doubling the integer part of W6, W6 = 1759/2 = 879.5. Of course, the value of C may be another numerical value.

W6 is 879.5 mm.
The length W7 of the short side of the lower tatami (4) is obtained by subtracting the length of the vertical line and the line segment from the bottom front to the bottom with W3 and W6 obtained above,
W7 = (0 + 2639.0)-(879.5 + 879.5)
= 880.0.
W7 is 880.0 mm.
The width of three tatami mats is 879.5mm, 879.5mm, and 880.0mm for W3, W6, and W7.

Next, the short side lengths W1, W2, W4, and W5 in the tatami mats (1) and (2) are obtained using W3 obtained by the calculation method. When W1 to W5 are located on the upper side and W3 is obtained, W1, W2, W4, and W5 are obtained by comparing W3 and the dimension data of the room at each measurement point.
For example, the calculation for obtaining the allocation data Wi by the difference in the dimension data of the upper side room is the same as the room dimension data Hi ( dimension data in the Y-axis direction at the measurement point) , the dimension data Hj (Y passing through the measurement reference point ) of the upper side room. (Axial dimension data) difference is expressed by adding the standard allocation data Wj,
Wi = Hi-Hj + Wj ・ ・ ・ [6]
It becomes.

W1, W2, W4, and W5 are calculated using Equation [6].
W1 = H1 Y coordinate-H3 + W3 = 0-0 + 879.5 = 879.5
W2 = H2 -H3 + W3 = -1.5-0 + 879.5 = 878.0
W4 = H4 -H3 + W3 = 1.5-0 + 879.5 = 881.0
W5 = Y coordinate of H5-H3 + W3 = 0-0 + 879.5 = 879.5
It becomes.

Next, the short side lengths W8 and W9 in the tatami (4) on the lower side of the room are obtained using W7.
When W8 and W9 are located on the bottom side and W7 is obtained, W8 and W9 are calculated using the above equation [6] by comparing W7 and the dimension data of the room at each measurement point.
W8 = H11-H10 + W7 = 2639.0-2639.0 + 879.5 = 879.5
W9 = H9 -H10 + W7 = 2637.5-2639.0 + 879.5 = 878.0
It becomes.

Since the sum of the dimension data of the long sides of the tatami (5) and the short sides of the tatami (3) and tatami (4) is the same, it can be expressed as Wt8 = W6 + W8. Wt8 = W6 + W8 = 879.5 + 879.5 = 1759.0
Since the sum of the dimension data of the long side of the tatami (6) and the room on the short side of the tatami (3) and tatami (4) is the same,
Wt9 = W6 + W9 = 879.5 + 878.0 = 1757.5.

Next, the long side lengths Wt7 and Wt10 in the tatami mats (5) and (6) are obtained using Wt8 and Wt9. Wt7 and Wt10 are calculated using Equation [6].
Wt7 = Y coordinate of H12-H11 + Wt8 = 2640.5-2639.0 + 1759.0 = 1760.5
Wt10 = Y coordinate of H8-H9 + Wt9 = 2637.5-2637.5 + 1757.5 = 1757.5
It becomes.

With the above calculation, the length of each side of the tatami mat placed in the room can be obtained.
Next, the length of each side of the tatami mat placed in the room is determined.

The left side point where the perpendicular in the X-axis direction from the measurement reference point intersects the threshold is Hm, the right side point is Hn, the number of half tatami mats corresponding to the width direction of the tatami existing between Hm and Hn (the above Hm, Hn The number obtained by dividing the length by the length in the width direction of the tatami) is s (for example, 4 in FIG. 4A), an arbitrary constant is c, and a value J obtained by multiplying the allocation data by c is used. In STP4, J = c (Hm + Hn) / s ... [7] is used to obtain the value of J, and then the decimal part of the quotient obtained from [7] in 2) is rounded down to obtain the integer part K of J Next, in 3), again, K is divided by c again to obtain J / c≈K / c = Wn, that is, the allocation data.
The above 2) can be expressed by using an integer K and a decimal point Δ that are rounded down to the first decimal place.
J = K + Δ.

The short side length W10 of the tatami mat (5) shown in FIG. 4 (b), the long side length Wt5 of the tatami mat (3), the short side length W13 of the tatami mat (6), FIG. 2 and FIG. The length component in the X-axis direction of the measurement point H14 on the left side shown in a) = 1.5 and the length component W13 in the X-axis direction of the measurement point H6 on the right side = 3519.5, and using the above 1) to 3), H _{14 dividing} the ingredients between H ₆ by the length W1 0 of the short side of the X-axis direction length tatami (5), and twice with arbitrary constant,
Determined from J = 2 (1.5 + 3519.5) /4=1760.5,
J is divided into an integer and a decimal, and J = 1760 + 0.5.
W10 is divided by an arbitrary constant c = 2 that doubles the integer part of the doubled number,
W10 = 1760/2 = 880.0.

W10 is 880.0 mm.
After obtaining W10, calculate in the order of W13, Wt5. The length W13 of the short side of the tatami mat (6) is obtained by subtracting the line passing through the measurement reference line in the horizontal direction by W10 obtained above, dividing by the number of tatami mats 3, and doubling by an arbitrary constant.
J = 2 (1.5 + 3519.5-880.0) /3=1760.666
J is divided into an integer and a decimal, and J = 1760 + 0.666.
W13 is divided by an arbitrary constant c = 2 that doubles the integer part of the number,
W13 = 1760/2 = 880.0.
Of course, the value of C may be another numerical value.

W13 is 880.0 mm.
The length Wt5 of the long side of the tatami mat (3) is obtained by subtracting the line segment passing through the measurement reference line in the horizontal direction by W10 and W13 obtained above.
Wt5 = (1.5 + 3519.5) − (880.0 + 880.0) = 1761.0.
Wt5 is 1761.0 mm.
The three tatami mats are 880.0mm, 880.0mm, and 1761.0mm (880.5mm in half) at W10, W13, and Wt5, and are evenly spaced by 0.5mm.

Since the allocation data Wt2 is a value obtained by dividing the tatami mat (1) and the tatami mat (2) into two equal parts, dividing the H14 room dimension data = 1.5 and the H6 room dimension data = 3519.5 by the number of tatami mats 2
Wt2 = (1.5 + 3519.5) /2=1760.5
Wt1 = H1 -H14 + Wt2 = 0-1.5 + 1760.5 = 1759.0
W11 = H13 -H14 + W10 = 3.0-1.5 + 880.0 = 881.5
W12 = Y coordinate of H12-H14 + W10 = 3.0-1.5 + 880.0 = 881.5
It becomes.

  With respect to the allocation data Wt4, Wt3, W14, and W15, the allocation data is obtained using the above method.

Next, conversion between 厘 units and millimeter units will be described with reference to FIG.
The first unit is 0.303 mm, and the unit of millimeter and unit is not an integer multiple, so once converted to millimeters / units by an electronic computer and then returned to the original unit, an error will occur. (10 ÷ 33 = 0.303 and × 3.3 cannot be returned to 1), and the error increases if this is repeated.

  As a method that does not cause an error, the converted value (MZ in Fig. 7) when converting from an absolute value to 厘 is expressed as an actual dimension converted from an absolute value to 厘, and a converted value from a deviation value to an absolute value (Fig. The occurrence of an error can be suppressed by expressing the MH) of 7 as an actual dimension obtained by adding the reference dimension to the deviation value.

This will be described with reference to FIG. 7. The tatami diagram in FIG. 7 (a) is obtained by rotating the tatami (1) in FIG. Reference numerals 1 to 7 in FIG. 7B are allocation data of the tatami mat (1) obtained by the equal allocation calculation method.
1 is a reference, 2 is a deviation from 1, 3 is Wt2, 4 is Wt1, 5 is W3, 6 is W2, and 7 is W1.

Mz = Wmm × 33/10
<SQ2> The value obtained by rounding up the converted value Mz to the first decimal place is N.
2. When calculating in millimeters,
Truncated at <SP3>.
The value of SP4 in millimeter units is smaller than the SP1 unit of MH.
In the calculation for the 厘 unit, rounding up makes the N value of the 厘 unit of SQ2 the same as the 値 unit value of SP1.
<SQ3> Subtract the reference dimension from the rounded value N to obtain the deviation value Wr.
Wr = N-Reference dimension

SQ1 to SQ3 will be described using the value of number 3.
<SQ1>
When converted to absolute value 1760.5, Mz = 1760.5 × 33/10 = 5809.65.
<SQ2>
The converted value Mz is rounded up to the first decimal place, and N is set to 5810.
The value of N in SQ2 and the value of MH in SP1 are the same.
<SQ3>
The deviation value Wr becomes Wr = 5810-5800 = 10 by subtracting the reference dimension 5800.
10mm is 10mm larger than the standard dimension.

Next, the case of inverse conversion from 厘 units (Wr) to metric units (Wmm) will be described.
The direction when converting from 厘 units (Wr) to millimeter units (Wmm) is B.
Conversion is performed by the method of SP1 to SP4.
<SP1> The value obtained by adding the reference dimension to the deviation value Wr is defined as MH as a conversion value.
MH = Wr deviation + reference dimension <SP2> conversion value MH is converted to mm (10/33), and a value obtained by multiplying C by a coefficient is L.
L = C × MH × 10/33
<SP3> L is divided into an integer K and a decimal point Δ.
L = K + Δ
<SP4> Divide integer K by coefficient C to obtain absolute value Wmm in millimeters.
Wmm = K / C

SP1 to SP4 will be described using the value of number 3.
<SP1>
The standard dimension 5800 is added to the deviation value 10 so that MH = 10.00 + 5800.00 = 5810.00.
<SP2>
Convert the converted value to MH in mm and multiply by C by the coefficient.
Since the unit is 0.5 mm, C is set to 2.
L = 2 × 5810.00 × 10/33 = 3521.21
<SP3>
If L is divided into an integer K and a decimal point Δ, and L = 3521 + 0.21, K becomes 3521.
<SP4>
The absolute value Wmm is K divided by 2, Wmm = 3521/2 = 1760.5, and the absolute value is 1760.5mm.

In STP1, the length and angle from a certain reference point are measured, the shape of the room is obtained by polar coordinates, and converted into XY coordinates as shown in FIG. 2, or inside the room as shown in FIG. The shape of the room is determined based on the length of the line segment obtained by drawing two lines perpendicular to the measurement reference point to the threshold of the room, and it is determined whether the unit of W is to be a ridge unit or a millimeter unit.
By measuring the dimensions of the room, the deviation at each measurement point is obtained in the unit of heel, and the length component on the coordinates at each measurement point is obtained in the unit of millimeter.

In STP2, in the case of 6 tatami mats, a perpendicular line is drawn from the point that bisects the upper side in the Y-axis direction, and the line segment between the upper side point and the lower side point that touches the sill is

  In STP6, the unit of W is determined. If the unit of W is in millimeters, the process proceeds to STP7. When the unit of W is the 厘 unit, the process proceeds to STP8.

  In STP7, if the unit of W is in millimeters in STP6, the tatami mats (1) to (6) are displayed in millimeter units Wmm. In STP6, when the unit of W is the 厘 unit and is switched to the millimeter unit, the converted value MH is calculated in STP9 and the tatami mats (1) to (6) are displayed in millimeter units Wmm using the formulas SP1 to SP4. .

In STP8, when converting from millimeter units to ８ units, the conversion value Mz = Wmm × 33/10 is calculated, and the actual length converted to 厘 units is obtained.

In such a case, at the measurement point where the step is generated (measurement point 3 in FIG. 6), two data are provided at one measurement point, such as H3a and H3b, as shown in the left figure. In this way, the tatami mats can be allocated by giving data by performing the measurement in the same manner as described above. Also in the places other than those shown in FIG. 6, there are cases where there is a step at a plurality of places instead of one place, so the measurement point where the tatami and the tatami are in contact is one measurement regardless of the number of tatami mats.
