[0010] (First embodiment) Hereinafter, a heating device 100 according to a first embodiment of the present invention and a cooking device 101 including the same will be described with reference to the drawings. Hereinafter, three orthogonal axes are set as shown in FIG. 1 etc. One side in the X-axis direction is designated as "front" and the other side as "rear", and the X-axis direction is also referred to as the "front-rear direction". One side in the Y-axis direction is designated as "left" and the other side as "right", and the Y-axis direction is also referred to as the "left-right direction". One side in the Z-axis direction is designated as "up" and the other side as "down", and the Z-axis direction is also referred to as the "up-down direction". In this embodiment, the Z-axis direction (up-down direction) is parallel to the vertical direction.

[0011] Cooking apparatus 101 is an automatic cooking apparatus for cooking ingredients. Specifically, cooking apparatus 101 is installed in, for example, a store, and cooks (stews) ingredients (meat, fish, vegetables, etc.) to provide the dish. In addition to stewing, cooking apparatus 101 may also be used for cooking other methods such as stir-frying, steaming, boiling, or deep-frying. The following description will be given taking as an example a case where the food to be cooked is a stewed meat dish such as a beef bowl. A stewed meat dish is cooked by stewing ingredients together with a sauce.

[0012] As shown in FIGS. 1 and 2, cooking device 101 includes pot 1 as a cooking vessel into which food to be cooked is placed, and heating device 100 for heating pot 1.

[0013] As shown in Figures 1 to 3, pot 1 has main body 2, which is a box-shaped container with a bottom and an opening at the top, and a partition plate 9 that divides the inside of main body 2 into two spaces. Main body 2 and partition plate 9 are both made of metal.

[0014] As shown in Figure 3, the main body 2 has a bottom wall 3 that is approximately rectangular when viewed from below in the vertical direction, and four side walls 4L, 4R, 4F, and 4B that extend upward from each side of the rectangular shape of the bottom wall 3.

[0015] Bottom wall 3 is formed in a flat plate shape perpendicular to the vertical direction. Hereinafter, the direction perpendicular to bottom wall 3 will also be referred to as the depth direction of pot 1. Pot 1 is placed in housing 10 of heating device 100 (described later) so that its depth direction coincides with the vertical direction.

[0016] A drain hole 3a is formed in bottom wall 3 for draining the contents of pot 1 (see Figure 1). A pipe P is connected to drain hole 3a, allowing the remaining contents and the like to be drained from pot 1 through pipe P. Furthermore, by providing drain hole 3a and pipe P, pot 1 can be washed and the water used for washing can be drained from pot 1 without removing pot 1 from housing 10.

[0017] 1 to 3, each side wall 4L, 4R, 4F, 4B has a tapered portion 5L, 5R, 5F, 5B that is inclined relative to the direction perpendicular to the bottom wall 3 (the up-down direction), and an upper wall portion 6L, 6R, 6F, 6B that is provided parallel to the up-down direction. A substantially rectangular opening is formed by the upper wall portions 6L, 6R, 6F, 6B of each side wall 4L, 4R, 4F, 4B. The upper wall portions 6L, 6R, 6F, 6B of each side wall 4L, 4R, 4F, 4B are connected to the bottom wall 3 by the tapered portions 5L, 5R, 5F, 5B of each side wall 4L, 4R, 4F, 4B.

[0018] As shown in Figure 1, the tapered portions 5F, 5B of the front and rear side walls 4F, 4B are inclined so that they extend front to back, away from the bottom wall 3 as they extend upward. As shown in Figure 2, the tapered portions 5L, 5R of the left and right side walls 4L, 4R are inclined so that they extend left to right, away from the bottom wall 3 as they extend upward. Therefore, in the area surrounded by the tapered portions 5L, 5R, 5F, 5B within the pot 1, the capacity per unit height decreases as it extends downward. Therefore, even when the content volume decreases, the liquid level can be kept high, making it easy to remove the contents.

[0019] Furthermore, the tapered portions 5B, 5L, 5R of the rear and left and right side walls 4B, 4L, 4R have the same inclination angle relative to the bottom wall 3. The tapered portion 5F of the front side wall 4F is formed to have a smaller inclination angle relative to the bottom wall 3 than the tapered portions 5B, 5L, 5R of the other three side walls 4B, 4L, 4R. In other words, the tapered portion 5F of the front side wall 4F is more gentle relative to the bottom wall 3 than the tapered portions 5B, 5L, 5R of the other three side walls 4B, 4L, 4R. The heights (vertical distances) from the bottom wall 3 of the tapered portions 5L, 5R, 5F, 5B of each side wall 4L, 4R, 4F, 4B are the same.

[0020] The partition plate 9 is detachably attached to the inside of the main body 2. The partition plate 9 is a plate-shaped member perpendicular to the front-to-rear direction and is provided inside the main body 2 across the entire vertical direction. By attaching the partition plate 9 to the main body 2, the internal space of the main body 2 is divided into two spaces (hereinafter also referred to as the "front space FS" and the "rear space BS") aligned in the front-to-rear direction. The partition plate 9 is also provided slidably inside the main body 2 along the front-to-rear direction. This allows the sizes of the front space FS and the rear space BS to be adjusted. The partition plate 9 is provided with one or more through holes 9a, and the two spaces separated by the partition plate 9 are connected via the through holes 9a of the partition plate 9.

[0021] The heating device 100 has a housing 10 that forms a storage space AS for storing the pot 1, a heating unit 20 that heats the pot 1 stored in the storage space AS, a temperature sensor 40 as a detection means for detecting the volume of the contents (food to be cooked) of the pot 1, and a control device 50 that controls the heating unit 20.

[0022] The housing 10 is a rectangular box, and inside the housing 10, a bottom support wall 11 and side support walls 12 are provided to support the main body 2 of the pot 1. The pot 1 is placed on the bottom support wall 11. The side support walls 12 support the top walls 6L, 6R, 6F, and 6B of the side walls 4L, 4R, 4F, and 4B of the main body 2 of the pot 1, surrounding them from the outside. The pot 1 is positioned within the housing 10 by the main body 2 coming into contact with the bottom support wall 11 and the side support walls 12. In this way, a storage space AS capable of storing the main body 2 of the pot 1 is formed inside the bottom support wall 11 and the side support walls 12. The storage space AS is open to the top plate of the housing 10, and the pot 1 can be stored in the storage space AS through the opening.

[0023] As shown in Figures 4 and 5, heating section 20 has a bottom wall heating section 22 that heats bottom wall 3 of main body 2 of pot 1, and a side wall heating section that heats side walls 4L, 4R, and 4B of main body 2. In the following, the configuration of heating section 20 will be described by setting an imaginary reference plane RP that passes through pot 1 and is perpendicular to the front-to-rear direction at approximately the center of pot 1 in the front-to-rear direction, as shown in Figures 4 and 5. In this embodiment, divider plate 9 of pot 1 is located at approximately the same position as reference plane RP.

[0024] Bottom wall heating unit 22 is a heating coil that heats pot 1 by electromagnetic induction. Bottom wall heating unit 22 is embedded in bottom support wall 11 of housing 10. As shown in FIG. 5 , bottom wall heating unit 22 is formed in a substantially oval shape when viewed from below. Bottom wall heating unit 22 is provided across substantially the entire width of bottom wall 3 in the left-right direction, but is not provided in a portion of the front side of bottom wall 3 in the front-rear direction. Bottom wall heating unit 22 is provided across the entire bottom wall 3 behind reference plane RP and a portion of the front side near reference plane RP. From another perspective, bottom wall heating unit 22 has its center C1 located rearward of the center C2 of the rectangular shape of bottom wall 3 in the front-rear direction. In this way, bottom wall heating unit 22 is positioned biased rearward in the front-rear direction, heating only a portion of the rear side of pot 1 without heating a portion of the front side.

[0025] As shown in Figure 4, the sidewall heating section includes a first sidewall heating section 23 and a second sidewall heating section 24, which is located closer to the bottom wall (lower) than first sidewall heating section 23 in the vertical direction. That is, in the vertical direction, first sidewall heating section 23, second sidewall heating section 24, and bottom wall heating section 22 are arranged in this order from top to bottom. First sidewall heating section 23 and second sidewall heating section 24 are each electric heaters that generate heat when electricity is applied. First sidewall heating section 23 and second sidewall heating section 24 contact main body 2 of pot 1 housed in casing 10 from the outside of main body 2.

[0026] As shown in Figure 5, first sidewall heating section 23 and second sidewall heating section 24 are each formed in a generally U-shape with an opening between both circumferential ends. First sidewall heating section 23 has a first base 23a extending across the entire left-right area of ​​rear sidewall 4B of main body 2 of pot 1, and a pair of first arms 23b and 23c extending forward from the end of first base 23a. First base 23a contacts sidewall 4B to heat it. First arm 23b contacts sidewall 4R, and first arm 23c contacts sidewall 4L to heat sidewalls 4R and 4L, respectively.

[0027] Second sidewall heating section 24 is formed in the same manner as first sidewall heating section 23. Second sidewall heating section 24 has second base section 24a extending across the entire left-right area of ​​rear sidewall 4B of main body 2 of pot 1, and a pair of second arms 24b, 24c extending from the ends of second base section 24a.

[0028] The pair of first arms 23b, 23c of the first sidewall heating unit 23 and the pair of second arms 24b, 24c of the second sidewall heating unit 24 are each provided only on a portion of the rear side in the front-to-rear direction, and not on a portion of the front side. In this way, the sidewall heating units are biased toward the rear side in the front-to-rear direction, heating a portion of the rear side of the pot 1 without heating a portion of the front side. In this embodiment, the pair of first arms 23b, 23c of the first sidewall heating unit 23 are provided to extend forward from the first base 23a to a position where their front-to-rear position approximately coincides with the reference plane RP. Similarly, the pair of second arms 24b, 24c of the second sidewall heating unit 24 are provided to extend forward from the second base 24a to a position where their front-to-rear position approximately coincides with the reference plane RP.

[0029] As described above, heating unit 20 is positioned toward the rear in the front-to-rear direction. Therefore, heating unit 20 is configured to be asymmetric with respect to reference plane RP. In this embodiment, the front-to-rear direction corresponds to a predetermined direction perpendicular to the depth direction of pot 1.

[0030] As shown in FIG. 1, temperature sensor 40 is inserted into rear space BS of pot 1 so as to extend in the depth direction (vertical direction) of pot 1. Temperature sensor 40 can measure the temperature inside pot 1 at multiple locations in the vertical direction. Normally, a temperature difference occurs between the contents placed in pot 1 and the air. Therefore, by measuring the temperature inside pot 1 with temperature sensor 40, it is possible to determine whether or not contents are present inside pot 1.

[0031] In this embodiment, temperature sensor 40 measures the temperature at three different positions (heights) in the vertical direction. Hereinafter, these will be referred to as "first measurement point P1," "second measurement point P2," and "third measurement point P3," in order from lowest to highest. By measuring the temperatures at three different heights in the depth direction using temperature sensor 40, the height of the contents inside pot 1 (mainly the liquid level of the sauce), and therefore the volume of the contents, can be detected.

[0032] In this embodiment, the volume of the contents of pot 1 is detected using three levels: "small," "medium," and "large." "Small" is a volume where the height of the contents of pot 1 is equal to or greater than the height of the first measurement point P1 of temperature sensor 40, but lower than the height of the second measurement point P2. "Medium" is a volume where the height of the contents of pot 1 is equal to or greater than the height of the second measurement point P2 of temperature sensor 40, but lower than the height of the third measurement point P3. "Large" is a volume where the height of the contents of pot 1 is higher than the height of the third measurement point P3. The volume where the height of the contents of pot 1 is equal to the height of the first measurement point P1 of temperature sensor 40 corresponds to the "first threshold," the volume where the height of the contents of pot 1 is equal to the height of the second measurement point P2 corresponds to the "second threshold," and the volume where the height of the contents of pot 1 is equal to the height of the third measurement point P3 corresponds to the "third threshold."

[0033] The control device 50 is configured by a computer including an arithmetic processing device such as a CPU, a storage device, a network connection device, etc. The storage device stores programs, applications, etc. in advance, and the CPU executes these programs to perform the various functions of the control device 50 described in this specification. The control device 50 may be configured as a single device, or may be divided into multiple devices and configured so that each control is distributed among the multiple devices.

[0034] When an operator operates the cooking button (not shown) on the operating device (not shown), the control device 50 detects the volume of the contents in the pot 1 based on the temperature measured by the temperature sensor 40, and outputs a control signal (current) to the heating unit 20 according to the volume, thereby activating the heating unit 20.

[0035] Next, a cooking method using the cooking apparatus 101 of this embodiment will be described.

[0036] In cooking apparatus 101, pot 1 is divided by divider plate 9 into a front space FS and a rear space BS. Heating unit 20 is located biased toward the rear in the front-to-rear direction. As a result, the amount of heat applied to pot 1 from heating unit 20 is greater toward the rear than toward the front in the front-to-rear direction. Thus, rear space BS of pot 1 is used for cooking, where food is heated and cooked, and front space FS of pot 1 is used for keeping the cooked food warm.

[0037] The cooking method will be specifically described below.

[0038] First, an operator places food to be cooked before cooking into the rear space BS of pot 1, which is used for cooking. When cooking meat, sauce and ingredients are placed into pot 1. The sauce placed in rear space BS of pot 1 also moves into front space FS through the through-hole 9a of partition plate 9. The ingredients cannot pass through through-hole 9a of partition plate 9 and therefore remain in rear space BS. In other words, through-hole 9a of partition plate 9 is sized to prevent ingredients from passing through.

[0039] Next, the operator presses the cooking button, which causes cooking device 101 to automatically cook the food to be cooked.

[0040] When the cooking button is pressed, a cooking start signal that starts automatic cooking is input to the control device 50. When the cooking start signal is input, the control device 50 acquires the temperature measured by the temperature sensor 40 and detects the volume of the contents in the pot 1 based on the temperature.

[0041] If the temperature sensor 40 detects the presence of contents at the first measurement point P1 but does not detect contents at the second measurement point P2 or the third measurement point P3, the capacity is determined to be "small." If contents are detected at the first measurement point P1 and the second measurement point P2 but not at the third measurement point P3, the capacity is determined to be "medium." If contents are detected at all of the first measurement point P1, the second measurement point P2, and the third measurement point P3, the capacity is determined to be "large."

[0042] Next, control device 50 supplies current to heating unit 20 according to the detected capacity of pot 1. If the capacity is "small" or "medium," a predetermined amount of current is supplied to bottom wall heating unit 22 and second side wall heating unit 24, and no current is supplied to first side wall heating unit 23.

[0043] When the capacity of pot 1 is "large," a predetermined amount of current is supplied to bottom wall heating section 22, first side wall heating section 23, and second side wall heating section 24.

[0044] In this way, the larger the content of pot 1 (in other words, the higher the liquid level), the more pot 1 is controlled to be heated by heating unit 20 located at a higher depth. Therefore, even if the content of pot 1 changes, the food to be cooked can be cooked automatically.

[0045] Furthermore, because heating unit 20 is positioned toward the rear in the front-to-rear direction, when heating unit 20 is activated by control device 50, the amount of heat applied from heating unit 20 to pot 1 is greater at the rear than at the front in the front-to-rear direction. This results in a relatively high temperature in rear space BS and a relatively low temperature in front space FS. Therefore, an operator can heat and cook ingredients in rear space BS of pot 1 and keep them warm by moving the cooked ingredients from rear space BS to front space FS.

[0046] According to the above embodiment, the following advantageous effects are achieved.

[0047] Heating device 100 is configured so that the amount of heat applied to pot 1 from heating unit 20 is greater on the rear side than on the front side. This allows food to be kept warm on the front side of pot 1 and cooked on the rear side, so that both keeping food warm and cooking can be performed in the same pot 1. This improves work efficiency and reduces costs compared to when keeping food warm and cooking are performed using separate devices.

[0048] Furthermore, in the heating device 100, the area for keeping the food warm and the area for cooking are separate within the same pot 1, so food that has been cooked can be easily moved to the area for keeping warm. This allows additional cooking to be performed without further simmering the already cooked food, and food can always be served in good condition.

[0049] Furthermore, in heating device 100, heating section 20 is positioned biased toward the rear in the front-to-rear direction. Therefore, by simply performing ON-OFF control to activate or stop heating section 20, control device 50 can control heating section 20 so that the amount of heat applied from heating section 20 to pot 1 is greater at the rear. In this way, heating device 100 does not require complex control by control device 50, and the device configuration can be simplified.

[0050] Furthermore, in heating device 100, the content volume of pot 1 is detected by measuring the temperature inside pot 1 using temperature sensor 40. Control device 50 controls heating unit 20 based on the content volume, so that the food to be cooked can be automatically heated and cooked according to the content volume.

[0051] (Second embodiment) Next, a heating device 200 according to a second embodiment of the present invention will be described with reference to Fig. 6. The following description will focus on differences from the first embodiment, and the same components as those in the first embodiment will be denoted by the same reference numerals and will not be described again.

[0052] In the first embodiment described above, the heating section 20 is positioned biased toward the rear in the front-to-rear direction, and the control device 50 controls the heating section 20 to turn on and off, so that the amount of heat applied to the pot 1 from the heating section 20 is greater at the rear in the front-to-rear direction than at the front.

[0053] In contrast, in the second embodiment, the heating section 20 is not arranged biased in the front-to-back direction, but the heating section 120 is controlled by the control device 50 so that the amount of heat applied to the pot 1 from the heating section 120 is greater at the rear side in the front-to-back direction than at the front side.

[0054] 6, the heating section 120 of the second embodiment has a front heating section 125 as a first heating section that heats the front side of the pot 1 in the front-to-back direction, and a rear heating section 121 as a second heating section that heats the rear side of the pot 1. Specifically, the front heating section 125 and the rear heating section 121 are arranged so as to be approximately symmetrical with respect to the reference plane RP.

[0055] Front heating section 125 has front bottom wall heating section 26 that heats bottom wall 3 of pot 1, and front side wall heating sections that heat side walls 4L, 4R, 4F of pot 1 (see FIG. 1).

[0056] Front bottom wall heating unit 26 is a heating coil that heats an object by electromagnetic induction. Front bottom wall heating unit 26 is provided on bottom support wall 11 (see FIG. 1) so as to face the front portion of bottom wall 3 of pot 1, which is forward of reference plane RP, and heats the front portion of bottom wall 3 of pot 1.

[0057] The front sidewall heating section includes a first front sidewall heating section 27 and a second front sidewall heating section 28 that is provided closer to the bottom wall 3 in the up-down direction than the first front sidewall heating section 27. The first front sidewall heating section 27 and the second front sidewall heating section 28 are each an electric heater that generates heat when electricity is applied. The first front sidewall heating section 27 and the second front sidewall heating section 28 are each formed in a U-shape, similar to the first sidewall heating section 23 and the second sidewall heating section 24 of the first embodiment.

[0058] First front sidewall heating section 27 has first base 27a extending across the entire left-right area of ​​main body 2 of pot 1, and a pair of first arms 27b, 27c extending rearward from the end of first base 27a. Similarly, second front sidewall heating section 28 has second base 28a and a pair of second arms 28b, 28c extending rearward from the end of second base 28a.

[0059] Rear heating section 121 has rear bottom wall heating section 22a that heats bottom wall 3 of pot 1, and rear side wall heating section 22a that heats side walls 4L, 4R, 4B of pot 1.

[0060] Rear bottom wall heating unit 22a is a heating coil that heats an object by electromagnetic induction. Rear bottom wall heating unit 22a is provided on bottom support wall 11 so as to face the rear half of bottom wall 3 of pot 1, which is located rearward of reference plane RP, and heats the rear portion of bottom wall 3 of pot 1.

[0061] The rear sidewall heating section has a first rear sidewall heating section 23 and a second rear sidewall heating section 24. The rear sidewall heating section has the same configuration as the sidewall heating section (first sidewall heating section 23, second sidewall heating section 24) in the first embodiment, and therefore a detailed description thereof will be omitted.

[0062] Control device 50 is configured to proportionally control the magnitude of the current supplied to heating unit 120. For example, control device 50 controls heating unit 120 so that it supplies a predetermined amount of current to front heating unit 125 and supplies a larger current to rear heating unit 121 than to front heating unit 125. In this way, control device 50 controls the operation of heating unit 120 so that the amount of heat applied to pot 1 from rear heating unit 121 is greater than the amount of heat applied to pot 1 from front heating unit 125.

[0063] In the second embodiment described above, the amount of heat applied to pot 1 from heating unit 120 is greater on the rear side than on the front side, so both keeping food warm and cooking can be performed within the same pot 1. This improves work efficiency and reduces costs compared to when keeping food warm and cooking are performed using separate devices.

[0064] Furthermore, in the second embodiment, front heating section 125 is provided to heat the front side of pot 1, so the warming temperature can be freely controlled by controlling the amount of heat generated by front heating section 125. In other words, according to the second embodiment, the warming temperature and the cooking temperature can be controlled separately, which increases the degree of freedom in cooking.

[0065] Next, modifications of each embodiment will be described.

[0066] In the first embodiment, the bottom wall heating unit 22 heats both the front and rear sides of the bottom wall 3 relative to the reference plane RP, while the first sidewall heating unit 23 and the second sidewall heating unit 24 heat only the rear sides of the sidewalls 4L and 4R, not the front sides relative to the reference plane RP. Alternatively, the bottom wall heating unit 22 may heat only the rear side of the bottom wall 3, while the first sidewall heating unit 23 and the second sidewall heating unit 24 heat a portion of the front side and the entire rear side of the sidewalls 4L and 4R. In other words, the first sidewall heating unit 23 and the second sidewall heating unit 24 may be configured so that the pair of first arms 23b, 23c and the pair of second arms 24b, 24c extend forward beyond the reference plane RP. Alternatively, one of the first sidewall heating unit 23 and the second sidewall heating unit 24 may be configured to heat both the front and rear sides of the pot 1, while the other heats only the rear side. Thus, in the first embodiment, the configuration of the heating section 20 is not limited to the configuration described in the above embodiment, and various forms can be adopted as long as the heating section 20 is positioned biased toward the rear in the front-to-rear direction and configured to apply more heat to the pot 1 at the rear side than at the front side.

[0067] In the first embodiment, the case where the control device 50 performs ON-OFF control on the heating unit 20 has been described. However, the control of the heating unit 20 by the control device 50 is not limited to ON-OFF control. For example, in the first embodiment, the control device 50 may control the heating unit 20 by proportional control, which proportionally controls the amount of current supplied.

[0068] In the second embodiment, the front heating section 125 and the rear heating section 121 are provided so as to be substantially symmetrical with respect to the reference plane RP on the front and rear sides in the front-to-rear direction, but the present invention is not limited to this configuration. The front heating section 125 and the rear heating section 121 may be different in arrangement or shape. Even in this case, the front heating section 125 and the rear heating section 121 can be individually controlled by the control device 50 to achieve the same effects as those of the above embodiment.

[0069] In the second embodiment, front heating section 125 and rear heating section 121 may share a common heating section. For example, a common bottom wall heating section may be provided to heat the entire bottom wall 3 of pot 1. In this case, front heating section 125 is composed of front sidewall heating sections (first front sidewall heating section 27, second front sidewall heating section 28), and rear heating section 121 is composed of rear sidewall heating sections (first rear sidewall heating section 23, second rear sidewall heating section 24).

[0070] In addition, in each of the above embodiments, the heating units 20, 120, i.e., the bottom wall heating unit 22, the rear bottom wall heating unit 22a, and the front bottom wall heating unit 26, are configured with heating coils that heat the pot 1 by induction heating. The first side wall heating unit 23 (first rear side wall heating unit 23), the second side wall heating unit 24 (second rear side wall heating unit 24), the first front side wall heating unit 27, and the second front side wall heating unit 28 are configured with electric heaters. In contrast, the heating units 20, 120 can use any heating method as long as they can heat the pot 1. For example, the heating unit that heats the bottom wall 3 may be an electric heater, and the heating units that heat the side walls 4L, 4R, 4F, and 4B may be induction heating coils. Furthermore, the heating method may be gas heating or the like.

[0071] Furthermore, in each of the above embodiments, the detection means was temperature sensor 40, but is not limited to this. The detection means may be, for example, a level gauge that detects the liquid level of the contents using a method other than temperature, or a weighing scale that measures the weight of the contents of pot 1. Furthermore, while temperature sensor 40 in each of the above embodiments measures the temperature of the contents of pot 1, it may instead measure the temperature of main body 2 of pot 1. Because the temperature of pot 1 itself changes depending on whether or not there is content, it is possible to detect the volume of the contents by measuring the temperature of pot 1. Furthermore, even when measuring the temperature at multiple locations, the detection means is not limited to a single temperature sensor 40, and may be composed of, for example, multiple temperature sensors.

[0072] In each embodiment, the control device 50 may be configured as a cloud server, partly or entirely, in a cloud environment.

[0073] The series of processes performed by the control device 50 described above may be provided as a program for causing a computer to execute the processes.

[0074] Furthermore, a program for executing the above-described series of processes is provided by a storage medium readable by the control device 50. Furthermore, the program may be provided to the control device 50 via a network line.

[0075] The various programs executed by the control device 50 may be stored in a non-transitory recording medium such as a CD-ROM.

[0076] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
