  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a schematic perspective view illustrating a system configuration of the first embodiment. FIG. 2 is a functional block diagram of a computer that controls this system.
This system is used in the process of attaching the joint hardware 14 to the precut material 12 for construction. The pre-cut material 12 is disposed on the work table 21 for attaching the joint hardware 14.

  The joint hardware 14 is stocked in the joint hardware component shelf 24. The joint hardware 14 is picked up by the pickup device 25 and delivered to the hardware supply device 26. The hardware supply device 26 travels along the hardware supply base 22 and pushes the joint hardware 14 to a designated place. In this embodiment, the metal fitting supply device includes a metal joint component shelf 24, a pickup device 25, and a metal supply device 26. The attachment operator 23 takes the joint hardware 14 and attaches it to the precut material 12. The display device 27 displays the mounting method. In addition, when the attachment operator 23 can directly take out the joint hardware 14 from the hardware supply device 26, the hardware supply device 26 can function as the hardware supply base 22. In other words, the joint hardware supply device can also serve as the hardware supply base. A plurality of hardware supply devices 26 may be provided. That is, the joining hardware supply device can take various forms.

  The computer 32 assists the attachment work of the joint hardware 14 by the attachment worker 23. When the joint hardware 14 is supplied all at once on the hardware supply base 22, the mounting operator 23 must select the joint hardware 14 to be operated next from the plurality of joint hardware 14. It has been found that the operation of selecting a corresponding one from a plurality of types of joint hardware 14 takes more time than expected. Therefore, in this system, the metal joints 14 are separately supplied with a set time in order of attachment.

  For this purpose, the computer 32 first determines all the metal fittings 14 to be attached to the precut material 12 arranged on the work table 21. Next, the attachment position of each joint hardware 14 to the precut material 12 is detected. Furthermore, the attachment order of the joint hardware 14 is determined for each precut material 12 in accordance with a predetermined condition. One set of the joint hardware 14 is used for mounting at a time. The hardware supply stand 22 is disposed adjacent to the precut material 12 as shown in the figure. Under the control of the computer 32, the metal joints 14 are separately supplied one by one to the hardware supply base 22 in the order of attachment already determined. The attachment worker 23 performs the attachment work of the joint hardware 14 in the supplied order.

  As shown in FIG. 2, the computer 32 includes an arithmetic processing device 34 and a storage device 36. The arithmetic processing unit 34 executes a computer program, thereby allowing the precut material selection means 13, the joining hardware determination means 16, the attachment position detection means 18, the attachment order determination means 20, the joining hardware supply control means 28, It functions as the precut material identification means 30.

  The storage device 36 stores CAD data 37 used for building design. In addition to this, various data are stored in the storage device 36, which will be described in order.

  The precut material 12 for construction is measured and preprocessed based on CAD data 37 created for designing a building. The CAD data 37 holds all the data such as the type and size of building materials of the building, the mounting position of the joint hardware, the size and position coordinates of the pre-processed portion for mounting. Each building material is pre-cut so that all the joint hardware can be attached. Wood attribute data 40 is assigned to each precut material thus obtained. Also, hardware identification data 42 is given to the joint hardware attached to the precut material. All of them are configured with numerical values and symbols, for example.

  The pre-cut material 12 is carried into a building site after being attached with a metal fitting 14 for joining with various other building materials. For example, there are several dozen to hundred types of joint hardware 14 used for the precut material 12 of a detached house, and one selected based on the CAD data 37 is attached. In the step of attaching the metal joint 14, the precut material 12 is disposed on a work table 21 provided for the work of attaching the metal joint 14.

  Bolt holes and mounting holes are formed in the precut material 12 in advance at locations where the joint hardware 14 is to be mounted. The attachment position of the joint hardware 14 is not necessarily the end of the precut material 12. In addition, in the case of a horizontal member having a square cross section, the bonding hardware 14 may be attached to, for example, two surfaces, three surfaces, or four surfaces in addition to one surface. The precut material 12 has various lengths such as about 1 m, 2 m, 4 m, and 6 m in total length. The attachment worker 23 repeats the work of attaching the metal joint 14 to the corresponding portion of the precut material 12 with the metal joint 14 in hand.

  In the present invention, one set is handed over in the order in which the metal fittings 14 are attached to the attachment operator 23 by computer control. As a result, the time required for the attachment operator 23 to search the metal fitting 14 from the parts shelf and move it to the attachment position is greatly reduced. For this purpose, a hardware supply device 26 is provided, and for the control thereof, an arithmetic processing unit 34 of the computer 32 is used to detect the metal fitting determination means 16, the attachment position detection means 18, the attachment order determination means 20, and the joint hardware supply control means. 28 is realized.

FIG. 3 is an external perspective view showing a specific example of the precut material 12.
The description will be made with reference to FIGS. At the start of work, the installation worker 23 takes out one precut material 12 from a material storage area (not shown) and places it on the work table 21. If the precut material 12 is placed in the order of removal, the attachment operator 23 takes out the precut material 12 in that order. Thus, the state shown in FIG. 1 is obtained. As shown in FIG. 3, the wood material data 38 is printed on the precut material 12. When this is read by the scanner 15, read data is transmitted to the computer 32. The wood identification data 38 is a barcode of a label that is printed or affixed. Alternatively, an IC tag may be used.

  The storage device 36 (FIG. 2) stores the wood identification data 38 and the wood attribute data 40 for all the precut materials 12. The wood attribute data 40 includes hardware identification data 42, attachment position data 44, attachment order data 46, attachment surface data 48, and supply location data 50 of all the joint hardware 14 attached to the precut material 12. Yes. When the precut material identification means 30 acquires the wood identification data 38, it passes the wood attribute data 40 of the corresponding wood identification data 38 to the joint hardware determination means 16. The joint hardware determination means 16 can determine the types of all joint hardware by acquiring the hardware identification data 42. In the example of FIG. 3, the hardware identification data 42 is printed for each place where the metal joint 14 on the side surface of the precut material 12 is attached. Note that an IC tag may be attached to the precut material 12 and the hardware identification data 42 of all the joint hardware 14 may be written on the IC tag.

  The attachment position detection means 18 has a function of detecting the attachment position of the metal joint 14 to the precut material 12. The hardware identification data 42 is attached with, for example, attachment position data 44 indicating that the joining hardware 14 is attached to a location of how many centimeters from one end of the precut material 12. Further, attachment surface data 48 indicating which surface of the precut material 12 is attached is also attached. The attachment position detection means 18 acquires the attachment position data 44 and the attachment surface data 48 for all the metal joints 14.

  The attachment order determining means 20 has a function of determining the attachment order of all the precut materials 12 according to predetermined conditions. For example, conditions such as attaching in order from the end of the pre-cut material, or attaching the same type of joint hardware at any place without changing the tool may be determined. In many cases, the metal joint 14 is, for example, a set of metal fittings and mounting screws or bolts. Therefore, the attachment order is determined for each of the joint hardwares 14, with each joint hardware 14 being used as a set for attachment. Accordingly, the attachment order determining means 20 generates data relating the wood identification data 38, the hardware identification data 42, the attachment position data 44, and the attachment order data 46. A calculation method for determining the mounting order will be described later.

  The hardware supply device 26 separately supplies the bonding hardware 14 one by one on the hardware supply table 22 in the mounting order determined by the mounting order determination means 20. The joint hardware supply control means 28 has a function of controlling the hardware supply device 26. The precut material 12 is disposed on the work table 21. The hardware supply table 22 is disposed adjacent to the precut material 12 on the work table 21. The metal joint 14 is automatically supplied onto the hardware supply base 22. Furthermore, the workability can be further improved by supplying the joint hardware 14 near the hardware mounting position of the precut material 12.

  The reason why the metal fitting 14 is supplied on the metal supply table 22 in order to eliminate the trouble of the installation operator selecting one set from a plurality of metal fittings. There are many similar shapes of joint hardware, and when many are arranged, it takes time other than the work of selecting one of them. This is solved here. It is not necessary to supply a plurality of sets of joint hardware simultaneously. Any structure may be used as long as it is supplied from the metal supply device 26 to the installation worker one by one in the order of installation. The pre-cut material 12 is disposed on the work table 21 for attaching the joint hardware 14. If it supplies on the metal supply stand 22 arrange | positioned adjacent to this precut material 12, a movement of an installation worker can be minimized. The hardware supply table 22 may not be in contact with the work table 21. Most preferably, it is adjacent to a place where the attachment worker can receive the joint hardware 14 by reaching out.

FIG. 4 is an explanatory diagram of processing for determining the supply position of the metal joint.
The hardware supply base 22 is divided into a plurality of regions as viewed in the longitudinal direction of the precut material 12. In the example of the figure, there are four sections. The above-mentioned joining hardware supply control means 28 controls so that the joining hardware 14 is supplied one by one to an area close to its mounting position. In the example shown in the figure, the joint hardware 14 is attached at a location close to the leftmost segment, the right adjacent segment, and the rightmost segment. Therefore, for example, the joining hardware 14 is supplied to these sections sequentially from the left side. Thereby, it is possible to automatically reduce the time for the attachment operator to move the attachment hardware to the attachment position.

  It is preferable that the metal supply table 22 has approximately the same length as the maximum length of the precut material 12 and is arranged in parallel to the work table 21 on which the precut material 12 is arranged. The hardware supply base 22 may be divided into a plurality of regions when viewed in the longitudinal direction of the pre-cut material 12, and one of the sections may be selected and controlled so as to supply the joint hardware 14 near the center of the section. The supply location data 50 may be generated in advance as described later. The number of sections may be freely determined according to the length of the precut material 12. When the precut material 12 is short, only one section may be used.

  In FIG. 1, a pickup device 25 picks up one set of bonding hardware one by one from a component shelf 24 that stocks the bonding hardware by type, and passes the picked-up hardware to a hardware supply device 26. The hardware supply device 26 travels in the longitudinal direction of the hardware supply base 22 and supplies the joint hardware 14 to a designated section on the hardware supply base 22. As the structure of the pickup device 25, a structure known in automatic warehouse related technology is adopted. The metal fitting supply control means 28 requests the pickup device 25 to pick up the metal fittings 14 one after another. Further, the joint hardware supply control means 28 controls the computer 32 to receive the joint hardware 14 one by one from the pickup device 25 in order and supply them to the hardware supply base 22. In this way, since the joint hardware is automatically picked up and supplied to the hardware supply table one by one, the workability of the installation worker can be improved.

FIG. 5 is an operation flowchart of processing for determining the mounting order.
Hereinafter, an embodiment of a computer program for realizing the system of the present invention will be described. The schematic operation of the main means described with reference to FIG. 2 will be described with reference to the flowcharts of FIGS. A more specific mounting order calculation processing method will be described below with reference to FIG.

  For example, first in step S11, the precut material selection means 13 acquires the wood identification data 38 of the precut material 12 to be worked on. The wood identification data 38 is listed in the precut material processing order data 52 in the processing order. It is assumed that the precut material selection means 13 operates so as to sequentially acquire the wood identification data 38 of the precut material 12 with reference to the precut material processing order data 52.

  It is preferable to generate precut material processing order data 52 by generating data in which precut material identification information is arranged in the order of stacking when precut materials are stacked, packaged and shipped. That is, it is preferable that the work of attaching the joint hardware to the precut material is performed in the order of the arranged wood identification data 38, and the precut material selection means 13 determines the precut material to be selected next. The precut material that has been attached to the joint hardware is packed and shipped to the construction site. If the selection order of the pre-cut materials is set in the packing order, they can be stacked and packed as they are.

  In the flowchart of this figure, for example, a process for determining the order in which the metal fittings are attached to all the precut materials 12 for one building is executed. In step S12, the acquired wood identification data 38 is set as a key, and the CAD data 37 of the corresponding precut material 12 is read. Next, in step S <b> 13, the joint hardware determination unit 16 reads the hardware identification data 42 of all joint hardware attached to the precut material 12. In step S14, the attachment position detection means 18 reads the attachment position data 44 of each metal joint. In step S15, the attachment surface data 48 of each joint hardware is read.

  In step S <b> 16, the attachment order determination means 20 performs an operation for determining the attachment order. The contents of this process will be described with reference to FIG. When the attachment order data 46 is determined, the attachment order data 46 is stored in the storage device 36 in step S17. Thus, with respect to one precut material 12, preparations for supplying the joint hardware one by one in an optimal order are completed. In step S18, it is determined whether or not the calculation for all the precut materials 12 has been completed. If the result of this determination is yes, the process ends. If no, the process returns to step S11.

FIG. 6 is an operation flowchart of the attachment order determining means 20.
When the calculation order is started, the attachment order determination means 20 first acquires the attachment position data 44 of all the joint hardware 14 in step S21. Next, in step S22, a closed loop candidate is generated. The closed loop refers to a path that returns from the reference position on the precut material 12 to the original reference position through all attachment positions. The reference position is set at one end of the precut material 12, for example. In step S23, the cumulative value of the movement distance (time) is calculated. In step S24, storage is performed when the accumulated value is smaller than the above candidate. The operation is to find a closed loop having the minimum value while detecting all candidates and comparing their accumulated values. Alternatively, as will be described later, the traveling salesman problem may be solved and solved.

  In step S25, it is determined whether there are other closed-loop candidates. If the result of this determination is yes, the process proceeds to step S22, and the processes from step S22 to step S25 are repeated. If no, the process proceeds to step S26. Here, the closed loop having the minimum value stored in step S24 is selected. In step S27, the attachment order of the metal fittings is determined according to the closed loop, and the attachment order data 46 is stored in the storage device.

  In the example of FIG. 6, focusing on only the movement distance (time) of the worker, the attachment order of the joint hardware capable of performing the work most quickly is obtained. To be precise, after placing the precut material 12 on the work table 21, go to the hardware supply table 22 to receive the joint metal 14, return to the corresponding part of the precut material 12, attach the joint metal 14, and again The cumulative value of the movement distance of the installation worker when the work of going to the hardware supply table 22 is repeated is obtained.

  This calculation can be adopted when the time required for the attachment work is almost the same for any joint hardware. However, among various types of metal fittings, there are some that take a relatively long time for attachment work, and some that can be attached in a very short time. Accordingly, using the attachment positions and the attachment times of all the joint hardware as parameters, the cumulative movement time and the cumulative attachment work time from the start to the end of the attachment work of all the joint hardware are obtained. It is good to determine the attachment order of the joint hardware which shows this accumulation time showing the minimum value. If the accumulated time obtained by adding the accumulated movement time and the accumulated mounting work time is obtained, the work efficiency can be more accurately evaluated. The travel time can be obtained by simply multiplying the travel distance by a certain number.

  In addition, there is a case where the moving distance may be increased for the joint hardware 14 that is more efficient when working together without changing the mounting tool. Even if the mounting position is close, the work efficiency decreases if the work of moving the pre-cut material 12 and replacing the joint hardware mounting surface is repeated.

  Therefore, the cumulative mounting work time includes the time for the mounting operator to move the joint hardware to the mounting position, the time for the mounting operator to change the mounting tool for the joint hardware, and the time for replacing the joint mounting surface of the precut material. Etc. should be included. This time may not be taken into account as long as the process of replacing the joint hardware attachment surface of the precut material is automated. A more specific calculation example will be described later with reference to FIG.

FIG. 7 is an operation flowchart of the metal joint supply control means 28.
In step S31, the precut material processing order data 52 stored in the storage device is read. In step S32, the precut material 12 to be worked is selected. In this example, it is assumed that the order of the precut materials 12 to be worked on is determined in advance in consideration of the order of packing after the attachment hardware is attached. Further, it is assumed that the precut material 12 is automatically supplied onto the work table 21 in this order. Accordingly, in step S33, the appearance of the next work precut material 12, the wood identification data 38, and the like are displayed on the display device 27 monitored by the installation worker 23.

  In step S <b> 34, the attachment operator 23 reads the wood identification data 38 of the precut material 12 using the scanner 15. In step S35, it is determined whether or not the precut material 12 matches the next work precut material 12. This is a process for preventing an erroneous conveyance of the precut material 12 and the like. If the result of this determination is yes, the process proceeds to step S36, and if no, the process returns to step S34. When returning to step S34, another precut material is placed on the work table 21 and the wood identification data 38 is read again.

  In step S36, a work start message is displayed on the display device 27. In step S37, the attachment order data 46 is displayed on the display device 27. For example, the contents of what kind of metal fittings are attached to the precut material 12 and the order of the attachments are as described above are displayed. This is to encourage the work preparation by the installation worker 23. In step S38, the joint metal fitting operation for the precut material 12 is actually controlled. This will be described with reference to FIG. In step S39, since the processing of the corresponding precut material 12 in step S38 is completed, the record is stored in the storage device. In step S40, it is determined whether or not the processing has been completed for all the precut materials 12. If the result of this determination is yes, the process is terminated. If no, the process returns to the process of step S31, and the process proceeds to the fitting attachment work for the next pre-cut material 12.

FIG. 8 is a specific operation flowchart of step S38 in FIG.
This process will be described with reference to FIG. In step S <b> 41, the joint hardware supply control unit 28 reads the attachment order data 46 of the joint hardware 14. In step S <b> 42, the joining hardware 14 corresponding to the pickup device 25 is acquired from the joining hardware component shelf 24 according to the mounting order. In step S43, the data of the joint hardware inventory management data 60 of the storage device is updated. In step S44, the hardware supply device 26 receives the metal joint 14 from the pickup device 25, and starts transporting. In step S45, the supply position on the metal supply stand 22 of the metal joint 14 is selected. Then, the hardware supply device 26 stands by at the supply position.

  In step S46, it is detected whether or not the work start button is depressed by the installation worker 23. The work start button may be displayed on the screen of the display device 27. The depression of the work start button is transmitted from the touch panel of the display device 27 to the computer 32. In step S47, an external view of the metal fitting 14 and an installation instruction are displayed on the display device 27. For example, information indicating the attachment position of the corresponding metal fitting to the precut material may be displayed in characters or graphics. The display screen may be generated by reading the CAD data by the joint metal supply unit. Further, for example, the attachment position of the next metal fitting may be notified by irradiating the precut material with a laser pointer. A plurality of laser pointers may be arranged on the hardware supply base 22, and each may irradiate the hardware mounting position of the precut material in order.

  The installation worker 23 proceeds with the installation work with reference to the display. In step S <b> 48, the hardware supply device 26 pushes the corresponding bonding hardware 14 onto the hardware supply base 22. The attachment operator 23 picks up the joining hardware 14 from the hardware supply base 22 and attaches it to the precut material 12.

  In step S49, the attachment completion record 54 of the metal joint 14 is created and stored in the storage device. When the metal joint 14 is pushed out onto the hardware supply base 22, this process may be executed with the logic that the metal joint always completes the mounting. Then, in step S50, it is determined whether or not the attachment of all the joint hardware 14 has been completed. When the result of this determination is yes, the processing of this flowchart is terminated. Then, the process proceeds to step S39 in FIG. If no, the process returns to the process of step S41 to proceed with the attachment control of the remaining joint hardware.

  In this embodiment, the worker 23 is made to operate the work start button. The button may be operated at the end of the work, not at the start of the work. By operating this button, the work acquisition means 31 can acquire and record the attachment work start time or attachment work end time of a set of metal fittings. Further, for example, when the hardware supply stand 22 is omitted and the mounting operator 23 directly takes out the tray on which the joint hardware is placed from the hardware supply device 26, a sensor is attached to the hardware supply device 26 and the tray is taken out. It is also possible to acquire the start time of the attachment work when it is done.

  For example, a voice switch or the like may be used to acquire the time when the attachment work starts or when the attachment work ends. However, the touch panel of the display device 27 formed of a tablet or the like may be used. For example, when the attachment operator 23 starts the attachment work of the next metal fitting 14, if the button displayed on the display device 27 is operated, the next set of metal fittings 14 is supplied onto the work table 21. Like that. The hardware supply device 26 may receive the joint hardware 14 to be attached next in advance from the pickup device 25 and wait in the vicinity of the work table 21. Alternatively, the work table 21 may be provided with a tray, a drawer, or a shelf for taking out the joint hardware 14 one by one in order. This specific time chart will be described later with reference to FIG.

FIG. 9 is a process flowchart after completion of attachment of all the precut materials.
First, in step S61, the processing completion record 56 of the precut material 12 stored in the storage device is read. In step S62, a daily work report 58 is generated. In step S63, the inventory management data 60 is read. In step S64, the metal joint 14 having a small stock quantity is detected. In step S65, the purchase order 62 for the corresponding joint hardware 14 is created. The above processing is automatically performed, and the result is displayed on the display device 27 to allow the installation operator 23 to confirm, or to be sent to a terminal of a manager in charge (not shown) and simultaneously stored in the storage device. By these treatments, it is possible to greatly speed up the work of attaching the metal joint to the precut material.

FIG. 10 is a time chart showing the relationship between the pickup of the joint hardware and the mounting operation.
As shown in the figure, the pick-up device 25 picks up the joint hardware 14 one by one from the joint hardware component shelf 24 in the order of attachment and stores them in a tray or the like (not shown). Then, the tray is placed in a standby place where the hardware supply device 26 arrives. After that, the next set of joining hardware may be picked up without waiting for the hardware supply device 26 to arrive.

  The hardware supply device 26 moves to the standby position, and takes in the tray in which the joint hardware is stored in the order of attachment. Then, the supply location of the joint hardware is read from the storage device and moved to the supply location. Here, the operation start button operation signal reception is awaited. Then, when the operation start button is operated, the tray in which the joint hardware is stored is pushed onto the hardware supply base 22. After that, it moves again to the standby position and takes in the tray in which the next metal fitting is accommodated. This operation is repeated. It is only necessary that the next tray is prepared by the pickup device 25 while the hardware supply device 26 returns to the standby position. The pickup device 25 operates at such timing.

  When the operator operates the work start button, there is no waiting time because the tray storing the joint hardware is pushed out from the hardware supply base 22 immediately. When the attachment work is started and the attachment work is completed, the operator operates the work start button again. In response to this, the tray in which the next joint hardware is stored from the hardware supply device 26 is pushed out onto the hardware supply base 22. The hardware supply device 26 may be controlled so that the tray is prepared and moved to the joint hardware supply location until the installation operator 23 next operates the operation start button.

FIGS. 11-14 is explanatory drawing of the example of a concrete arithmetic processing of a joining metal fitting attachment order.
First, as shown in FIG. 11, the positions for supplying hardware are set to (i), (b), (c), and (d) from the joint metal mounting position of the precut material. In the part indicated as the hardware set, the type of the joint hardware and the number of parts attached to each place are displayed. The part names of the joint hardware are shown in the margin on the right side of the figure.

FIG. 12 is a plan view showing the relationship between the attachment position of the precut material and the attachment surface.
The pre-cut material has a square cross section, and each surface is indicated as P, Q, R, S surface. For example, on the P surface, a metal joint is attached at the position (c).

FIG. 13 is an explanatory diagram of an arithmetic processing table.
Thus, the moving time table, the wood rotation time table, the tool setup replacement time table, and the attachment time table are created for the arithmetic processing. The origin was set at the left end of the precut material in FIG. 12, and the travel time from the origin to each joint fitting mounting position was displayed in the travel time table. The wood rotation time is the time from when the surface enumerated and displayed in the column direction is up to when the surface displayed in the row direction is up.

  In addition, if the attachment of all the metal fittings to a precut material is completed, after that, a precut material will be moved as it is, without rotating. Further, it was assumed that the pre-cut material was always supplied with a certain surface up (mounting work surface).

The tool setup change time table indicates the time required to change the tool necessary for the attachment of the joint hardware at the attachment position of each joint hardware. It was assumed that this time was always required when the first fitting was attached.

The attachment time table indicates the attachment time of each joint hardware at each attachment position . The total time table shows the total required time at each joint hardware mounting position . Looking at this table, it can be seen from what position to which position the next joint hardware is attached and what the total of the moving time, the time for rotating the wood, the time for changing the tool, and the attaching time will be.

FIG. 14 is an explanatory diagram for obtaining the order of the shortest time from the above total time table.
For example, (a) is an order in which the work is started from the state where the worker is at the origin, and the corresponding joint hardware is attached while moving in the order of (a) (b) (c) (d) and then returned to the origin. Indicates. At this time, “19” from the origin to (b), “14” from (b) to (b), “24” from (b) to (c), and (c) from (d) ) And “16” from (d) to the origin are added to calculate the accumulated time “102”.

  In the same manner, the cumulative time is calculated and compared for all the mounting orders. In this case, if a well-known solution of the traveling salesman problem is used, an answer can be obtained without listing all the mounting orders obtained as combinations. Therefore, this is a reasonable calculation method. As a result, the work is started from the state where the worker is at the origin, and the order of attaching the corresponding joint hardware and returning to the origin while moving in the order of (b) (b) (d) (c) is the shortest. It was. This calculation example is an example, but a simple calculation process can be performed by preparing a calculation table as shown in FIG.

  Note that the computer program executed by the arithmetic processing unit may be modularized in units illustrated in functional blocks, or may be integrated by combining a plurality of functional blocks. Further, the above computer program may be used by being incorporated into an existing application program. The computer program for realizing the present invention can be recorded on a computer-readable recording medium such as a CD-ROM and installed in any information processing apparatus for use.
