Embodiments for Carrying Out the Invention

[0011] An embodiment of the present invention will be described with reference to FIGS. 1 to 12.

[0012] Reference numeral 1 in the figure is a remote control operation device which is an operation device for an agricultural work machine used in an agricultural work machine. This remote control operation device 1 can be commonly used for a plurality of types of agricultural work machines connected to the rear part of a tractor which is a traveling vehicle.

[0013] That is, the remote control operation device 1 for an agricultural work machine can be commonly used for a plurality of types, that is, for example, two types of agricultural work machines, a ridging machine and a weeding machine, which can be connected to the three-point link at the rear part of the tractor.

[0014] The state shown in FIG. 1 is a state when remotely operating a ridging machine which is one agricultural work machine (a state when in use for the ridging machine), and the state shown in FIG. 9 is a state when remotely operating a weeding machine which is another agricultural work machine (a state when in use for the weeding machine). And in any case, the remote control operation device 1 for an agricultural work machine is electrically connected to a control unit (which may be a control unit of the tractor) of the corresponding agricultural work machine which is a remote control object, either by wire or wirelessly, and is arranged at a position where an operator sitting on the driver's seat of the tractor can operate it.

[0015] The remote control operation device (operation box) 1 is electrically connected to the control unit of the agricultural work machine to be operated, and includes a device main body 2 that can communicate with the control unit, and a plurality of types (for example, two types) of detachable bodies 3 and 4 that are detachable from the device main body 2 and correspond to a plurality of types (for example, two types) of agricultural work machines, namely, a ridging machine and a rotary cultivator. Note that the detachable body 3 shown in FIG. 1 is for the ridging machine, and the detachable body 4 shown in FIG. 9 is for the rotary cultivator.

[0016] The detachable bodies 3 and 4 have a three-dimensional shape that bulges convexly toward the side opposite to the device main body 2 at least when attached to the device main body 2 (see FIGS. 3, 10, etc.).

[0017] That is, the detachable bodies 3 and 4 are formed of, for example, an elastically deformable soft synthetic resin into a three-dimensional shape that bulges convexly (for example, a curved shape convex forward) toward the front, which is the side opposite to the device main body 2, at least in the state of being attached to the device main body 2. That is, each of the detachable bodies 3 and 4 is not a flat plate, but a three-dimensional resin part (replacement part) having a three-dimensional shape such as an arch shape.

[0018] The device main body 2 includes a rectangular main body part 11 when viewed from the front, a plurality (for example, 21 in total, arranged in 3 rows and 7 columns) of circular push-button type switch parts 13 protruding in a matrix shape on the planar front surface (switch surface that is the front) 12 of the main body part 11, a waterproof sheet 14 that is a waterproof means attached to the front surface 12 of the main body part 11 so as to cover these plurality of switch parts 13, and a color liquid crystal display part 15 that is an information display means protruding from the upper part of the main body part 11.

[0019] The liquid crystal display part 15 displays predetermined information including, for example, information about the agricultural work machine to be operated and information about the operation content. Thereby, even when the detachable bodies 3 and 4 are replaced, it is easy to understand, and it is possible to prevent incorrect operations by the operator.

[0020] Furthermore, a rectangular, annular mounting portion 16 is provided projecting forward from the outer periphery of the front surface 12 of the main body 11. The detachable parts 3 and 4 are detachable (fittable) from the mounting portion 16 of the device body 2. The switch portion 13 provided on the front surface 12 of the main body 11 has different functions depending on the type of agricultural machine it corresponds to, for example.

[0021] The detachable body 3 for the ridge-forming machine consists of a plurality (for example, three) of detachable members that can be individually attached to and detached from the mounting portion 16 of the device body 2, namely the first detachable member 21, the second detachable member 22, and the third detachable member 23 arranged in the vertical direction.

[0022] In other words, the detachable body 3 consists of detachable members 21, 22, and 23, which are divided into three parts vertically, and each of these detachable members 21, 22, and 23 is integrally formed from a flexible synthetic resin that is elastically deformable. Furthermore, these three detachable members 21, 22, and 23 include, for example, members of different colors. That is, for example, the first detachable member 21 is blue, the second detachable member 22 is yellow, and the third detachable member 23 is red.

[0023] The first detachable member 21 has a detachable main body 31 that is elongated in the left-right direction, and a plurality of (for example, seven) operating parts 32 (32a to 32g shown in Figure 6) integrally provided on the detachable main body 31. When the detachable main body 31 is attached to the device body 2, these plurality of (for example, seven) operating parts 32 are positioned in close proximity to a plurality of switch parts 13 located on the upper part of the front surface 12 of the main body 11. As a result, the operator can operate the switch part 13 corresponding to the operating part 32 by pressing and operating the operating part 32 of the first detachable member 21.

[0024] The detachable main body 31 has a pair of opposing plates 33 that are spaced apart from each other and bent front plate 34 that connects the front ends of these opposing plates 33, and a plurality of (for example, seven) operating parts 32 are provided on this front plate 34.

[0025] The front plate 34 has a central parallel plate portion 35 positioned parallel to the front surface 12 of the main body portion 11 of the device body 2, and left and right inclined plate portions 36 positioned inclined with respect to the front surface 12. The inclined plate portions 36 are inclined so that the inner end side, which is on the parallel plate portion 35 side, is positioned further forward. In other words, when the first detachable member 21 is attached to the device body 2, the distance between the front surface 12 of the main body portion 11 and the inclined plate portion 36 gradually increases from the outer end to the inner end of the inclined plate portion 36.

[0026] Furthermore, of the front plate 34 of the detachable main body 31 of the first detachable member 21, for example, three operating parts 32 are provided on the central parallel plate portion 35, for example, two operating parts 32 are provided on the left inclined plate portion 36, and for example, two operating parts 32 are provided on the right inclined plate portion 36. Note that the operating parts 32 provided on the inclined plate portion 36 may have their front surfaces formed inclined relative to the front surface of the inclined plate portion 36.

[0027] Each operating section 32 (32a to 32g) has a forward-projecting portion (protruding button portion) 37 that protrudes forward from the front plate 34 of the detachable main body 31, and a rear-projecting portion 38 that protrudes rearward from the front plate 34 of the detachable main body 31. The front surface of the forward-projecting portion 37 is marked with an indication of the contents of the operating section 32 (for example, the words or figures "Multiple," "Shallow," "Mode," "Recent Operation," and "Previous Operation"). The rear-projecting portion 38 has a contact portion 39 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0028] The second detachable member 22 is similar to the first detachable member 21, and has a detachable main body 41 that is elongated in the left-right direction, and a plurality of (for example, six) operating parts 42 (42a to 42f shown in Figure 6) integrally provided on the detachable main body 41. When the detachable main body 41 is attached to the device body 2, these plurality of (for example, six) operating parts 42 are positioned in close proximity to a plurality of switch parts 13 located in the vertical center of the front surface 12 of the main body 11. As a result, the operator can operate the switch part 13 corresponding to the operating part 42 by pressing the operating part 42 of the second detachable member 22.

[0029] The detachable main body 41, like that of the first detachable member 21, has a pair of opposing plates 43 that are spaced apart from each other and a bent front plate 44 that connects the front ends of these two opposing plates 43, and a plurality of (for example, six) operating parts 42 are provided on this front plate 44.

[0030] The front plate 44 has a central parallel plate portion 45 positioned parallel to the front surface 12 of the main body portion 11 of the device body 2, and left and right inclined plate portions 46 positioned inclined with respect to the front surface 12. The inclined plate portions 46 are inclined so that the inner end side, which is on the parallel plate portion 45 side, is positioned further forward. In other words, when the second detachable member 22 is attached to the device body 2, the distance between the front surface 12 of the main body portion 11 and the inclined plate portions 46 gradually increases from the outer end to the inner end of the inclined plate portions 46.

[0031] Furthermore, of the front plate 44 of the detachable main body 41 of the second detachable member 22, for example, three operating parts 42 are provided on the central parallel plate portion 45, for example, one operating part 42 is provided on the left inclined plate portion 46, and for example, two operating parts 42 are provided on the right inclined plate portion 46.

[0032] Each operating section 42 (42a to 42f), like that of the first detachable member 21, has a forward-projecting portion (protruding button portion) 47 that protrudes forward from the front plate 44 of the detachable main body 41, and a rear-projecting portion 48 that protrudes rearward from the front plate 44 of the detachable main body 41. The front surface of the forward-projecting portion 47 is marked with an indication of the content of the operating section 42 (for example, the words or figures "Water Spray", "Confirm", "On", and "Out"). The rear-projecting portion 48 has a contact portion 49 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0033] The third detachable member 23 is similar to the first detachable member 21, and has a detachable main body 51 that is elongated in the left-right direction, and a plurality of (for example, five) operating parts 52 (52a to 52e shown in Figure 6) integrally provided on this detachable main body 51. When the detachable main body 51 is attached to the device body 2, these plurality of (for example, five) operating parts 52 are positioned in close proximity to a plurality of switch parts 13 located at the lower part of the front surface 12 of the main body 11. As a result, the operator can operate the switch part 13 corresponding to the operating part 52 by pressing the operating part 52 of the third detachable member 23.

[0034] The detachable main body 51, like that of the first detachable member 21, has a pair of opposing plates 53 that are spaced apart from each other and a bent front plate 54 that connects the front ends of these opposing plates 53, and multiple (for example, five) operating parts 52 are provided on this front plate 54.

[0035] The front plate 54 has a central parallel plate portion 55 positioned parallel to the front surface 12 of the main body portion 11 of the device body 2, and left and right inclined plate portions 56 positioned inclined with respect to the front surface 12. The inclined plate portions 56 are inclined so that the inner end side, which is on the parallel plate portion 55 side, is positioned further forward. In other words, when the third detachable member 23 is attached to the device body 2, the distance between the front surface 12 of the main body portion 11 and the inclined plate portion 56 gradually increases from the outer end to the inner end of the inclined plate portion 56.

[0036] Furthermore, of the front plate 54 of the detachable main body 51 of the third detachable member 23, for example, two operating parts 52 are provided on the central parallel plate portion 55, for example, two operating parts 52 are provided on the left inclined plate portion 56, and for example, one operating part 52 is provided on the right inclined plate portion 56.

[0037] Each operating section 52 (52a to 52e), like that of the first detachable member 21, has a forward-projecting portion (a protruding button portion) 57 that protrudes forward from the front plate 54 of the detachable main body 51, and a rearward-projecting portion 58 that protrudes rearward from the front plate 54 of the detachable main body 51. The front surface of the forward-projecting portion 57 is marked with an indication of the content of the operating section 52 (for example, the words or figures "Low", "Deep", "Set", and "Store"). The rearward-projecting portion 58 has a contact portion 59 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0038] The first detachable member 21, the second detachable member 22, and the third detachable member 23 are then attached to the main body 2 so as to cover the front surface 12 of the main body portion 11, thereby forming a curved (including substantially curved) detachable body 3 that bulges out in a convex shape toward the front. In other words, this detachable body 3 consists of a combination of the three detachable members 21, 22, and 23.

[0039] As shown in Figure 1, the detachable body 3 is for a ridge-forming machine and has multiple operating parts (buttons) 32, 42, 52 on its bulging front surface, corresponding to the multiple switch parts 13 of the main body of the device 2, namely, for example, 18 buttons.

[0040] Here, the multiple operating units 32, 42, and 52 (hereinafter sometimes collectively referred to as "operating unit group 3a") include those with different forward protrusion heights (protrusion dimensions) from the front plates 34, 44, and 54 of the detachable main body units 31, 41, and 51, depending on predetermined conditions (for example, frequency of operation, operation content, position, etc.).

[0041] In other words, for example, among the operating parts group 3a, those that are operated relatively frequently have forward-projecting portions 37, 47, and 57 that protrude at a first projection height A, while those that are operated relatively infrequently have forward-projecting portions 37, 47, and 57 that protrude at a second projection height B that is lower than the first projection height A (see Figure 8(b), etc.).

[0042] In the example shown in Figure 6, for example, a plurality of buttons, including the "Confirm" button 42c and the four directional pad buttons 32d, 42b, 42d, 52c located around it, for example, nine buttons 32b, 32d, 42b, 42c, 42d, 42e, 42f, 52b, 52c, are tall buttons (buttons with a large protrusion dimension that are easy to press) having a first protrusion height A, while the others are low buttons (buttons with a small protrusion dimension that are difficult to press) having a second protrusion height B. Note that the system is not limited to these two types of protrusion heights; for example, there may be three or more types of protrusion heights, buttons with zero protrusion height may be included, or all buttons may have the same protrusion height.

[0043] Furthermore, the multiple operating parts 32, 42, and 52 include those with different shapes for the forward-protruding portions 37, 47, and 57 depending on predetermined conditions. For example, the forward-protruding portions 37, 47, and 57 are formed in a circular, rectangular, or triangular shape.

[0044] The detachable body 4 for the puddling machine consists of a plurality of detachable members (for example, three) that can be individually attached to and detached from the mounting portion 16 of the device body 2, namely the first detachable member 61, the second detachable member 62, and the third detachable member 63, which are arranged in the left-right direction.

[0045] In other words, the detachable body 4 consists of detachable members 61, 62, and 63, which are divided members, for example, into three parts, left and right. Each of these detachable members 61, 62, and 63 is integrally formed from a flexible synthetic resin that is elastically deformable (the same material as detachable members 21, 22, and 23). Furthermore, these three detachable members 61, 62, and 63 include, for example, members of different colors. That is, for example, the first detachable member 61 is blue, the second detachable member 62 is yellow, and the third detachable member 63 is red.

[0046] The first detachable member 61 has a rectangular detachable body portion 71 in front view, and a plurality of (for example, six) operating portions 72 (72a to 72f shown in Figure 11) integrally provided on the detachable body portion 71. When the detachable body portion 71 is attached to the device body 2, these plurality of (for example, six) operating portions 72 are positioned in close proximity to a plurality of switch portions 13 located on the left side of the front surface 12 of the main body portion 11. As a result, the operator can operate the switch portion 13 corresponding to the operating portion 72 by pressing the operating portion 72 of the first detachable member 61.

[0047] The detachable main body 71 has a pair of opposing plates 73 that are spaced apart from each other, an inclined front plate 74 that connects the front ends of both opposing plates 73, and a side plate 70 that connects the right ends of both opposing plates 73. Multiple (for example, six) operating parts 72 are provided on the inclined front plate 74. The front plate 74 is also inclined so that the right end, which is on the side of the second detachable member 62, is positioned further forward. In other words, when the first detachable member 61 is attached to the device body 2, the distance between the front surface 12 of the main body 11 and the front plate 74 gradually increases from the left end to the right end of the front plate 74.

[0048] Furthermore, the front plate 74 of the attachment / detachment main body 71 of the first attachment / detachment member 61 is provided with a plurality of operation parts 72 arranged in a matrix, for example, in a 3x2 arrangement, totaling 6 operation parts 72.

[0049] Each operating section 72 (72a to 72f) has a forward-projecting portion (protruding button portion) 77 that protrudes forward from the front plate 74 of the detachable main body 71, and a rear-projecting portion 78 that protrudes rearward from the front plate 74 of the detachable main body 71. The front surface of the forward-projecting portion 77 is marked with a display indicating the function of the operating section 72 (for example, the words "Open," "Close," "Plowing," and "Earth Pulling"). The rear-projecting portion 78 has a contact portion 79 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0050] The second detachable member 62 has a detachable main body 81 that is elongated in the left-right direction, and, for example, one operating part 82 integrally provided in the left-right center of the detachable main body 81. When the detachable main body 81 is attached to the device body 2, the operating part 82 is positioned in close proximity to a switch part 13 located in the upper center of the front surface 12 of the main body 11. As a result, the operator can operate the switch part 13 corresponding to the operating part 82 by pressing the operating part 82 of the second detachable member 62.

[0051] The detachable main body 81 has a pair of opposing plates 83 that are spaced apart from each other, a front plate 84 that connects the front ends of both opposing plates 83, and left and right side plates 80 that connect the left and right side ends of both opposing plates 83, and an operating section 82 is provided on the front plate 84.

[0052] Since the front plate 84 is positioned parallel to the front surface 12 of the main body 11 when the second detachable member 62 is attached to the device body 2, the distance between the front surface 12 of the main body 11 and the front plate 84 is constant. An operating section 82 is provided in the center of the front plate 74 in the left-right direction.

[0053] The operating section 82 has a forward-projecting portion (a protruding button portion) 87 that protrudes forward from the front plate 84 of the detachable main body 81, and a rear-projecting portion 88 that protrudes rearward from the front plate 84 of the detachable main body 81. The front surface of the forward-projecting portion 87 is marked with an indication of the contents of the operating section 82 (for example, a graphic indicating that it is a power button). The rear-projecting portion 88 has a contact portion 89 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0054] The third detachable member 63 is similar to the first detachable member 61, and has a rectangular detachable body portion 91 in front view, and a plurality (for example, six) of operating portions 92 (92a to 92f shown in Figure 11) integrally provided on this detachable body portion 91. When the detachable body portion 91 is attached to the device body 2, these plurality (for example, six) of operating portions 92 are positioned in close proximity to a plurality of switch portions 13 located on the right side of the front surface 12 of the main body portion 11. As a result, the operator can operate the switch portion 13 corresponding to the operating portion 92 by pressing the operating portion 92 of the third detachable member 63.

[0055] The detachable main body 91 has a pair of opposing plates 93 that are spaced apart from each other, an inclined front plate 94 that connects the front ends of both opposing plates 93, and a side plate 90 that connects the left ends of both opposing plates 93. Multiple (for example, six) operating parts 92 are provided on the inclined front plate 94. The front plate 94 is also inclined so that the left end, which is on the side of the second detachable member 62, is positioned further forward. In other words, when the third detachable member 63 is attached to the device body 2, the distance between the front surface 12 of the main body 11 and the front plate 94 gradually increases from the right end to the left end of the front plate 94.

[0056] Furthermore, the front plate 94 of the attachment / detachment main body 91 of the third attachment / detachment member 63 is provided with a plurality of operation parts 92 arranged in a matrix, for example, in a 3x2 arrangement, totaling six operation parts 92.

[0057] Each operating section 92 (92a to 92f) has a forward-projecting portion (protruding button portion) 97 that protrudes forward from the front plate 94 of the detachable main body 91, and a rear-projecting portion 98 that protrudes rearward from the front plate 94 of the detachable main body 91. The front surface of the forward-projecting portion 97 is marked with a display indicating the contents of the operating section 92 (for example, the words "Open," "Close," "Close Simultaneously," and "Open Simultaneously"). The rear-projecting portion 98 has a contact portion 99 at its rear end that contacts the switch portion 13 via the waterproof sheet 14.

[0058] The first detachable member 61, the second detachable member 62, and the third detachable member 63 are then attached to the main body 2 so as to cover the front surface 12 of the main body portion 11, thereby forming a curved (including substantially curved) detachable body 4 that bulges out in a convex shape toward the front. In other words, this detachable body 4 consists of a combination of the three detachable members 61, 62, and 63.

[0059] As shown in Figure 9, the detachable body 4 is for a rice paddy tilling machine and has multiple operating parts (buttons) 72, 82, 92 on its bulging front surface that correspond to multiple switch parts 13 of the main body of the device 2, namely, for example, 13 buttons.

[0060] Furthermore, the multiple operating parts 72, 82, and 92 (hereinafter sometimes referred to collectively as "operating part group 4a") also include those with different protruding heights and shapes (for example, at least one of the protruding height, shape, and color) according to predetermined conditions, similar to the operating part group 3a of the detachable body 3 shown in Figure 1.

[0061] In other words, for example, in the example shown in Figure 11, of the group of operating parts 4a, eight operating parts 72a, 72b, 72c, 72d, 92a, 92b, 92c, and 92d are tall buttons with a first protrusion height A, while the others are short buttons with a second protrusion height B.

[0062] Furthermore, when attaching the detachable members 61, 62, and 63 that constitute the detachable body 4 for the plowing machine to the main body 2 of the device, a cover body 100 is detachably attached to cover the unused switch section (a group of unused switch sections consisting of multiple adjacent unused switch sections) 13 that are not used when operating the plowing machine.

[0063] The cover body 100 is integrally formed from, for example, a hard synthetic resin (a different material from the detachable bodies 3 and 4), and has a pair of opposing plates 101 that are spaced apart from each other, a front plate 102 that connects the front ends of both opposing plates 101, and left and right side plates 103 that connect the left and right side ends of both opposing plates 101. The front plate 102 of the cover body 100 does not have an operating section (button), and the front surface of the front plate 102 is a flat surface.

[0064] Next, we will explain the operation of the remote control device 1.

[0065] For example, when performing levee plastering work by connecting a levee plastering machine to the rear of a tractor, as shown in Figure 1, the detachable body 3 for the levee plastering machine is attached to the main unit 2 of the device, and with the main unit 2 and the control unit of the levee plastering machine electrically connected, the operator operates the group of control units 3a of the detachable body 3 as appropriate while viewing the information displayed on the liquid crystal display unit 15.

[0066] For example, pressing the "Settings" control panel 52d (settings button) will enter editing mode for the offset and tillage depth settings. In this editing mode, you can change the settings using the left and right control panels 42b and 42d of the directional pad, change items (change pages) using the up and down control panels 32d and 52c of the directional pad, and confirm and finish editing by pressing the "Confirm" control panel 42c (confirm button) in the center.

[0067] Furthermore, by operating the "Mode" control unit 32e, for example, it is possible to select between a manual mode in which the movable part of the agricultural implement is moved to a set value by continuously pressing the control unit, or an automatic mode in which the movable part is moved to the set value automatically with a single push.

[0068] On the other hand, for example, when a puddling machine is attached to the rear of a tractor to perform puddling work, as shown in Figure 9, the detachable body 4 for the puddling machine is attached to the main unit 2 of the device, and with the main unit 2 and the control unit of the puddling machine electrically connected, the operator operates the group of control units 4a of the detachable body 4 as appropriate while looking at the information displayed on the liquid crystal display unit 15.

[0069] Furthermore, according to the remote control operating device 1 described above, the detachable bodies 3 and 4, which are made of elastically deformable three-dimensional resin parts, have a three-dimensional shape that bulges out toward the opposite side from the device body 2 when attached to the device body 2. Therefore, compared to conventional remote control operating devices, the operating parts 32, 42, 52, 72, 82, and 92 are easier to operate, the display on the front of the operating parts is also easier to see, improving operability, and moreover, it allows for greater design freedom and improved aesthetics.

[0070] Furthermore, since the detachable body 3 consists of multiple detachable members (divided members) 21, 22, 23 that can be individually attached to and detached from the main body 2, and the detachable body 4 consists of multiple detachable members (divided members) 61, 62, 63 that can be individually attached to and detached from the main body 2, for example, if one of the multiple members needs to be replaced due to damage or deterioration, only that detachable member needs to be replaced with a new one, thus reducing maintenance costs.

[0071] Furthermore, since the multiple operating parts constituting the operating part groups 3a and 4a of the detachable bodies 3 and 4 include those with different forward protrusion heights from the main body of the detachable body (protrusion dimensions on the opposite side from the main body of the device) depending on predetermined conditions, operability is further improved, and errors by the operator can be prevented.

[0072] Furthermore, since the main unit 2 of the device has a liquid crystal display unit 15 that displays various information, it can more effectively prevent operator errors.

[0073] Here, Figure 13 is an example of a screen displayed on the liquid crystal display unit 15, and the screen shown in Figure 13 is, for example, a pairing setting screen. As shown in Figure 13, this pairing setting screen has a display unit 10 that displays side by side the names of agricultural machines that can be paired (wirelessly connected) with the remote control operating device 1 and the ID numbers corresponding to each agricultural machine.

[0074] Then, the operator selects and confirms the agricultural machine to be paired (for example, the "harrow" to which it will be connected) by appropriately operating the control panel, such as the directional keys and the select button, while looking at the display unit 10.

[0075] At this time, if the agricultural machine to be paired is within a predetermined distance from the remote control device 1 (if it is not present, an error message will be displayed and an alarm will sound), the pairing setup will be completed, and the function (role) of the switch section 13 on the main unit 2 will switch to that of the paired machine. That is, for example, the function of the up button on the directional pad for a levee plastering machine will switch to the function of the power button for a puddling machine.

[0076] In the above embodiment, a remote control device for agricultural machinery that can be used in common for multiple types of agricultural machinery was described. However, a dedicated control device that can be used for only one type of agricultural machinery (for example, a levee-forming machine) may also be used.

[0077] Furthermore, if the operating device is usable for multiple types of agricultural machinery (an operating box compatible with multiple models), it is not limited to the two types of levee-forming machines and puddling machines mentioned above, but may also be used for, for example, a brush cutter, a sprayer, a ditch-digging machine, a crop harvester, etc., and may be used for three or more types. The multiple types of agricultural machinery that can be connected to the operating device are displayed, for example, on the display unit of the device itself.

[0078] Furthermore, the detachable body is not limited to having multiple detachable members that can be individually attached to and detached from the main body of the device; for example, it may consist of only one detachable member.

[0079] Furthermore, when the detachable body is composed of multiple detachable members (divided members), it may be composed of multiple detachable members divided in both the vertical and horizontal directions, for example, and the method of division is arbitrary. Also, for example, the multiple detachable members may include some that are commonly used for multiple types of agricultural machinery.

[0080] Furthermore, the detachable body only needs to have a three-dimensional shape when attached to the main body of the device. For example, it may have a shape that bulges concavely toward the opposite side of the main body when attached, or a dome-shaped bulge. Alternatively, it may not have a three-dimensional shape in its state before elastic deformation (before attachment), but may take on a three-dimensional shape when elastically deformed and attached to the main body of the device.

[0081] Furthermore, the forward-protruding portion of the operating section is not limited to having a fixed thickness and a predetermined protruding height; for example, it may have a thickness that gradually changes.

[0082] Furthermore, it is preferable that the front surface of the forward-protruding portion of the control unit has an indicator to show the operation content. However, it is also possible to indicate the operation content by the shape of the control unit itself (for example, the arrow shape of a directional pad) without adding an indicator.

[0083] Furthermore, the mounting portion of the device body to which the detachable parts are attached may be, for example, a grid-like mounting portion to which each detachable member is individually attached.

[0084] Furthermore, the method of attaching the detachable body to the main body of the device (attachment means) is arbitrary. For example, it may be fixed with double-sided tape that can be repeatedly attached, with a snap-in member (not shown), with a suction cup, with screws, with a magnet, with hook-and-loop fastener, etc., and multiple attachment methods may be combined as appropriate.
