When the setting button 38f is pressed for a long time, the operation input unit 44 processes it as an instruction to switch the display between the information display mode 70 and the selection mode 74 described later. That is, long pressing of the confirmation button 38e is a specific operation according to the present invention.

However, the specific operation is not limited to long pressing of the set button 38e. For example, it may be continuous hitting of the confirmation button 38e, or simultaneous short pressing of the confirmation button 38e and other buttons, or a certain button provided on the operating tool 38 may be pressed in a predetermined rhythm, A combination thereof may be used.

In addition, when the operation input unit 44 continues to press the confirmation button 38e, for example, for 1 to 2 seconds or more (hereinafter referred to as "long press"), an information display mode 70 described later and specified mode 84 (see FIG. 20) as an instruction to switch the display. When the setting button 38f is pressed for a long time, the operation input unit 44 processes it as an instruction to switch the display between the information display mode 70 and the selection mode 74 described later.

The operation for switching the display between the information display mode 70 and the specific mode 84 is not limited to long pressing of the set button 38e. For example, it may be continuous hitting of the confirmation button 38e, or simultaneous short pressing of the confirmation button 38e and other buttons, or a certain button provided on the operating tool 38 may be pressed in a predetermined rhythm, A combination thereof may be used.

The operation tools 38 are arranged inside the trapezoidal opening 31c, and the operation surfaces of the operation button groups 38a to 38d and the operation surfaces of the setting buttons 38f are concave from the surface of the housing 31. placed in position. The risk of misoperation of the operating tool 38 when the worker unintentionally touches the display device 30 is reduced.

[Display control device]

The display control device 40 includes a screen control unit 41, a display communication unit 42, a display storage unit 43, an operation input unit 44, and emission control units 45 and 46, and is operated from the operation unit 33. The display device 30 is controlled based on a signal or various types of information obtained from the gas control device 20 . The display control device 40 is composed of a microcomputer in which a CPU, ROM, RAM, I/O, and the like are mounted on a board 36.

The screen control unit 41 displays predetermined characters, images, etc. on the screen unit 34 in a predetermined manner. In the display storage unit 43, background images according to various kinds of information are stored. The screen control unit 41 calls the background image stored in the display storage unit 43, and also includes a graph-type image whose length changes according to various types of information, a scale plate area in which unit scales are arranged in an arc shape, and various Depending on the information, a tachometer as a meter-type image composed of pointers indicating values according to various types of information may be displayed on the screen unit 34 by rotating around the center of the scale plate area as a rotation axis.

Further, the graph-type image may be one whose length changes step by step or linearly according to various types of information, and is configured so that segments are stacked along a predetermined direction. For example, the graph-type image may be a bar graph configured such that unit scales are arranged along the curved vertical direction and a predetermined display color is displayed between unit scales according to various information. In addition, the predetermined display color may be one color or a plurality of colors. In addition, a stepwise change in color tone, contrast, or the like is included. Therefore, in the following description, the case where the graph-type image is a bar graph will be described. At this time, the screen control unit 41 is configured to display the segments with different weights (weights), for example, to display them with different intervals between unit scales of the bar graph.

2 , on the screen unit 34, travel speed, automatic vehicle speed control state, zip processing state (cutter, dropper), auxiliary transmission state, harvesting height, type of object to be harvested, barrel load level, sheave Information images such as load level, taste, water quantity, engine rotation speed, water temperature, remaining amount of element SCR, radio wave reception strength, driving time, GPS positioning status and date and time are displayed.

Even if the same information is provided day and night, the screen control unit 41 increases the brightness during the day and displays it as an information image based on white, for example, as shown in FIG. 2, and lowers the brightness at night. As shown in , for example, it is possible to display an information image based on black, and its visibility is enhanced by display according to day and night. Incidentally, such switching is configured to be possible by an operation in a setting mode 80 described later, but it may be configured so that the switching is performed automatically depending on the time zone.

Hereinafter, various images displayed on the screen portion 34 will be described.

The screen control unit 41 divides the screen unit 34 up and down in a horizontal direction by a straight boundary. In this embodiment, as shown in FIG. 2 , the upper side is the main area 50 and the lower side is the sub area 51 . In addition, the boundary between the main area 50 and the sub area 51 just needs to be defined by the screen control unit 41, and does not necessarily have to be a clearly recognizable aspect for humans. The same applies to each other area described below.

[Main area]

In the main area 50, since information images according to main information among various types of information related to the machine of the combine 1 or the setting or status for work by the combine 1 are displayed, most of the screen portion 34, In this embodiment, about 90% of the space is allocated.

The main information includes driving speed, automatic vehicle speed control status, zip processing status (cutter, dropper), auxiliary transmission status, mowing height, type of mowing object, barrel load level, sheave load level, seasoning, quantity, Various notification information such as engine rotation speed, water temperature, remaining amount of urea SCR, fuel level, radio wave reception strength, and the like are included. In addition, the display area for radio wave reception strength is fixedly provided in the lower right corner of the main area 50 .

The screen controller 41 is configured by dividing the main area 50 into a fixed display area 52 and a variable display area 53.

In the fixed display area 52, a specific information image corresponding to specific information is displayed at least among various types of information related to the body of the combine 1 or the setting or status of work by the combine 1. Specific information is information that is preferably displayed at all times during operation of the combine 1, travel speed, state of automatic vehicle speed control, state of zip processing (cutter, dropper), state of auxiliary transmission, height of mowing, object to be mowed The type of and rotational speed of the engine are included.

The fixed display area 52 is arrange|positioned at the position slightly right of the center among the main area 50, and the travel speed of the combine 1 is displayed by the numerical value in the center of the fixed display area 52.

Regarding the travel speed of the combine 1, the machine control device 20 calculates the travel speed calculated from the travel speed detected by the travel speed sensor 1a provided in the travel section and the time-lapse position based on the GPS signal. The amount of change is compared, and when the two do not match (when they diverge by more than a predetermined threshold value), it is determined that slip or failure has occurred in the combine 1, and travel speed calculated from the amount of change in position over time based on the GPS signal is transmitted to the display control device 40, and this is displayed on the screen unit 34.

On the other hand, the machine control device 20 is a case where the travel speed calculated from the amount of change in position over time based on the GPS signal exceeds the maximum speed at which the combine 1 can travel, or a combine where a change in speed over time is normally expected If it is out of the behavior of (1), it is conceivable that the GPS positioning state is not good, so the travel speed detected from the travel speed sensor 1a provided in the travel section is transmitted to the display control device 40, This is displayed on the screen portion 34.

That is, the screen control unit 41 includes a plurality of detection means (traveling speed sensor 1a and GPS receiver Based on each detection result by (25)), it is configured so that a predetermined status information image according to predetermined status information (traveling speed) can be displayed on the screen portion 34.

Under the information image corresponding to the traveling speed, the state of straw processing (dropper), the state of the auxiliary transmission (section H), the height of harvesting (example L), and the type of object to be harvested (rice) are displayed by characters or icons.

In addition, when the automatic vehicle speed control is functioning, that is, the reaping unit 2 or the threshing unit 3 or the like is in an overloaded state, and the vehicle speed is automatically lowered than the traveling speed according to the operation amount of the main gear lever 14, When there is, "Decelerating" is displayed by text on the upper right side of the information image corresponding to the traveling speed.

During deceleration of the vehicle speed by the automatic vehicle speed control, the display of "during deceleration", for example, lights up for 1 second and turns off for 1 second repeatedly. This makes it easy for the worker to confirm that the vehicle speed is automatically decelerated and controlled. Even when the vehicle speed is being automatically decelerated controlled, if the automatic vehicle speed control function is turned OFF, the deceleration control is stopped. Then, the body is increased to the original traveling speed according to the operation amount of the main gear lever 14. The possibility of occurrence of such a situation can be alerted to the worker.

The rotational speed of the engine is displayed by a tachometer around the numerical value representing the traveling speed of the fixed display area 52 . The tachometer is composed of a scale plate area in which unit scales are arranged in an arc shape, and a guide that rotates according to the rotation speed of the engine around the center of the scale plate area as a rotation axis to indicate a value corresponding to the rotation speed.

In this way, by arranging the fixed display area 52 near the center of the screen portion 34, visibility and design of various information displayed on the screen portion 34 are improved.

In this embodiment, the screen control unit 41 sets the variable display area 53 at two places on the left and right of the fixed display area 52, and has an arbitrary shape along the outer circumference of the scale area of the fixed display area 52. It is divided into display areas 53a to 53d.

The screen control unit 41 displays a selection information image according to information selected based on an artificial instruction from among various types of information in each of the arbitrary display areas 53a to 53d, or an information image according to a certain information based on an artificial instruction. It is constituted so that setting is not also displayed.

The selected information that can be displayed on the arbitrary display areas 53a to 53d includes at least numerical information indicating settings or states by numerical values, and increase/decrease information indicating settings or states by at least bar graphs.

As numerical information, taste, quantity, and fuel level can be exemplified, and as increase/decrease information, quantity, load level of a sieve, water temperature, remaining amount of urea SCR, and fuel level can be exemplified. The specific information about the specific information image displayed on the fixed display area 52 and the information about the selection information image that can be displayed on the variable display area 53 are different. Information displayed in the fixed display area 52 and the variable display area 53 is not covered.

Taste, quantity, and fuel level as numerical information are classified into "taste/quantity (statistics)", "taste/quantity", "taste", and "quantity/fuel", and as increase/decrease information, quantity and sieve load level , water temperature, remaining amount of urea SCR, and fuel level are classified into "rice level", "sieve level", "remaining amount of urea SCR", "fuel level", and "water temperature".

In the screen portion 34 shown in Fig. 2, an arbitrary display area 53a displays an image of selection information according to "taste/quantity (statistics)" … (%), average moisture... … (%), and integrated heavy weight... … Images including letters and numbers are displayed, such as (kg).

In the screen portion 34 shown in Fig. 2, an image including an icon representing the water temperature and a curved bar graph is displayed as a selection information image according to "water temperature" in the arbitrary display area 53b. The bar graph displays the water temperature by displaying figures of a predetermined size and a predetermined display color between predetermined unit graduations arranged along the vertical direction. In this embodiment, the number of graduations is 8, and the upper one among them is set as the threshold level.

In the screen portion 34 shown in Fig. 2, an image including an icon representing the rice level and a curved bar graph is displayed as a selection information image according to "rice level" in the arbitrary display area 53c. In the bar graph, the rice level is displayed by displaying figures of a predetermined size and a predetermined display color between predetermined unit scales arranged along the vertical direction. In this embodiment, the number of graduations is 10, and the upper two of them are set as threshold levels.

The screen controller 41 is configured to make the number of scales different according to the type of object to be harvested. In this embodiment, since the type of object to be harvested is "rice" and has a calibration curve, the calculation part can calculate the yield of rice from the weight of the storage part 5 detected by the weight sensor 5b. Since the weight of the reservoir 5 can be calculated linearly, the resolution is high. In this case, the screen control unit 41 displays the selection information image according to "rice level" in detail using a bar graph having a scale of 10.

Moreover, if the type of object to be harvested is a grain which does not have a calibration curve, a calculation part cannot calculate the yield of rice from the weight of the storage part 5 detected by the weight sensor 5b. In this case, the storage height of rice stored in the reservoir 5 is directly detected by the level sensor 5c. However, the reservoir height can only be detected when rice is brought into contact with the level sensor 5c. Between the level sensors 5c provided at positions with different heights, the reservoir height cannot be detected. However, since the detected result is the storage height of actually stored rice, reliability is high. In such a case, the screen control unit 41 roughly displays the result of the selection information image according to the "rice level" using a bar graph having a scale of 4.

In addition, the number of graduations such as 10 or 4 is an example, and may be appropriately set in advance, or may be arbitrarily set by an operator, or may be automatically or manually switched depending on a working machine in which the display device 30 is provided. The selection information image related to "rice level" is a predetermined state information image.

In the screen portion 34 shown in FIG. 2, an image including an icon representing the sieve level and a curved bar graph is displayed as a selection information image according to "sieve level" in an arbitrary display area 53d. . In the bar graph, the sheave level is displayed by displaying a figure of a predetermined size and a predetermined display color between predetermined unit graduations arranged along the vertical direction. In this embodiment, the number of graduations is 5, and the upper one among them is set as the threshold level.

The screen control unit 41 calls a background image according to various types of information from among the background images stored in the display storage unit 43, and displays, for example, a predetermined display color between numerical values, characters, and predetermined scales. , an information image corresponding to each of the various types of information is formed and displayed on the screen unit 34 according to an aspect according to the various types of information.

Here, as shown in Fig. 6, when the screen portion 34 is in the information display mode 70, when the setting button 38f of the operating tool 38 is pressed and held, as shown in Fig. 6, an arbitrary display area ( 53a to 53d), transition is made to the selection mode 74 in which information corresponding to the information image to be displayed can be selected.

In this selection mode 74, a drum roll type selection image 53e is arranged at a location corresponding to the fixed display area 52. By briefly pressing the up button 38a or the down button 38c of the control tool 38, the selection image 53e rotates up or down, and when the set button 38e is briefly pressed on a predetermined item, it is arbitrarily Among the display areas 53a to 53d, information corresponding to the information image to be displayed is displayed in an arbitrary display area that is a target of switching. Further, in the selection mode 74, by briefly pressing the left button 38b or the right button 38d, among the arbitrary display areas 53a to 53d, the information corresponding to the information image to be displayed is displayed at an arbitrary target of switching. area can be switched.

As information that can be switched, as described above, numerical information classified into items such as "taste/quantity (statistics)", "taste/quantity", "taste", and "quantity/fuel", "rice level", Increase/decrease information classified into items such as "sieve level", "residual amount of element SCR", "fuel level", and "water temperature" exists.

When "taste/quantity" is selected, as a selection information image corresponding to this, protein... … (%), moisture… … (%), and rice... … An image including letters and numbers, such as (kg), is displayed.

When "Gourmet" is selected, as a selection information image corresponding to this, protein... … (%), and moisture... … An image including characters and numerical values is displayed as in (%).

As a selection information image according to "amount of water and fuel", rice . . . … (kg), fuel consumption quantity… … As shown in (L), an image including characters and numerical values is displayed.

As the selection information image according to the "remaining amount of element SCR", an image including an icon indicating remaining amount of element SCR and a curved bar graph is displayed. The bar graph displays the element SCR remaining amount by displaying a figure of a predetermined size and a predetermined display color between predetermined unit scales arranged along the vertical direction. In the present embodiment, the number of scales is 1, and the threshold level is set from 0 level to about 10 to 20% of the full tank level side of the full tank level.

As the selection information image according to "fuel level", an image including an icon indicating the fuel level and a curved bar graph is displayed. Further, the bar graph displays the fuel level by displaying figures of a predetermined size and a predetermined display color between predetermined unit scales arranged along the vertical direction. In this embodiment, the number of graduations is 1 from the 0 level to the full tank level, and the threshold level is set at about 10 to 20% of the full tank level side from the 0 level to the full tank level.

The screen control unit 41 displays numerical information images according to numerical information, that is, "taste/quantity (statistics)", "taste/quantity", "taste" and "quantity/fuel" in a plurality of arbitrary display areas 53a. to 53d), it is configured to be displayed only in the arbitrary display area 53a located at the leftmost side of the screen unit 34.

Therefore, in the leftmost arbitrary display area 53a, "taste/quantity (statistics)", "taste/quantity", "taste", "quantity/fuel", "rice level", "sieve level", It is structured so that any item can be selected from 10 items of "Element SCR remaining amount", "Fuel level", "Water temperature", and "None" which means that no information image corresponding to any information is displayed.

For example, as shown in FIG. 6 , information corresponding to a selection information image to be displayed can be switched from “taste/quantity (statistics)” to “element SCR remaining amount” in an arbitrary display area 53a. .

As shown in Fig. 6, when displaying numerical information, here, a numerical information image based on "taste/quantity (statistics)" in the arbitrary display area 53a, an information image based on the "taste/quantity (statistics)" The arbitrary display area 53a to display is expanded and displayed in the arbitrary display area 53a, rather than when displaying the increase/decrease information, here, the increase/decrease information image according to the "element SCR remaining amount".

In numerical information images such as "taste/quantity (statistics)" and increase/decrease information images such as "element SCR remaining amount", the numerical information images require a wider space to display. As described above, when a numerical information image corresponding to numerical information is displayed, the visibility of numerical information is improved by allocating a sufficient space.

Further, in the selection mode 74, as shown in Fig. 7, the information corresponding to the selection information image to be displayed is changed from "taste/quantity (statistics)" to "none" for the arbitrary display area 53a. can switch

At this time, the screen control unit 41 is configured so that the selection information image for "water temperature" displayed in the arbitrary display area 53b is extended to the arbitrary display area 53a side and displayed.

Specifically, the display storage unit 43 stores background images with different widths even if the same information, here, is an information image according to "water temperature", and the screen control unit 41 stores the wider background image. In addition to displaying, by displaying a predetermined display color on the scale, an information image according to "water temperature" is formed, and this is displayed on the screen portion 34.

The screen control unit 41 displays "rice level", "sieve level", "urea SCR remaining amount", "fuel level", "water temperature", It is structured so that any item can be selected from among 6 items of "none".

In addition, even if the same information, for example, the same "fuel level" information, the screen control unit 41 converts the information image into an arbitrary display area 53a, an arbitrary display area 53b, and an arbitrary display area 53c. and the arbitrary display area 53d is configured to be displayed in a different manner, for example, by making the shape of an image to be displayed different.

Specifically, the display storage unit 43 stores the same information, for example, a background image inverted left and right even if it is an information image according to "fuel level", and the screen control unit 41 displays It is configured to display a background image having a shape corresponding to the selected arbitrary display area and display a predetermined display color on the grid. In this way, various kinds of information can be displayed in a way that improves designability without adversely affecting visibility by making various information different according to the shape of the arbitrary display areas 53a to 53d to be displayed on the screen portion 34. .

In the above-described embodiment, the case where the information to be displayed in the arbitrary display areas 53a to 53d is different has been described, but it is not limited to this. The screen control unit 41 can display an information image corresponding to the same information in all of the arbitrary display areas 53a to 53d, or, for example, only one item "rice level" among the arbitrary display areas 53a to 53d. It is also possible to display an information image according to the above, and not display an information image according to the item "none", that is, according to any information, in other arbitrary display areas.

In addition, the screen control unit 41 displays the information image according to the "rice level" in the arbitrary display areas 53a to 53d, the quantity of rice based on the stored amount of rice detected by the level sensor 5c is displayed in the arbitrary display area 53c, for example, in the form of a bar graph having a scale of 4, and at the same time, as described above, the storage part 5 detected by the weight sensor 5b The yield of rice calculated from the weight can also be displayed in, for example, an arbitrary display area 53d in the form of a bar graph having a scale of 10 (see Fig. 19).

As shown in Fig. 8, the display control device 40 displays a plurality of patterns of screen states selected for information to be displayed in arbitrary display areas 53a to 53d among various types of information, and three patterns in this embodiment. (43), and the screen control unit 41 displays the screen state to be displayed on the screen unit 34 among the screen states of the three patterns stored in the display storage unit, based on an artificial instruction, for example By briefly pressing the left button 38b and the right button 38d of the operating tool 38, it is configured to scroll and switch.

The three-pattern screen states are internally identified in the display storage unit 43 by numbering, for example, screen number 71, screen number 72, screen number 73, and the screens of each screen number 71, 72, and 73. When returning to the information display mode (70) after transitioning from the state to the setting mode (80), screen states according to screen numbers 71, 72, and 73 immediately before the transition to the setting mode (80) are displayed.

Moreover, at the time of start-up of the combine 1, the screen state corresponding to the screen number displayed just before stop of the combine 1 is displayed. That is, when the combine 1 is stopped last time at the time of start-up of the combine 1, since the screen state which the worker was watching last is displayed, it is easy to use.

However, it is not limited to the configuration in which the screen state corresponding to the screen number displayed immediately before the stop of the combine 1 is displayed when the combine 1 is started, and when the combine 1 is started, a screen number specified each time It may be configured so that the screen state of (eg 71) is displayed. In addition, at the time of starting the combine 1, whether to display the screen state according to the screen number that was displayed immediately before the stop of the combine 1, or to display the screen state corresponding to a specific screen number is configured to be settable There may be.

As shown in Fig. 9, in the setting mode 80, items related to setting are grouped and divided into a work tab 81, a meter tab 82, and a PF tab 83 for display.

In the work tab 81, each item of maintenance time, alarm history, and user can be selected. In the item "user", registration of a plurality of users, for example, six users, and switching thereof are possible. In the item "alarm history", it is possible to store and display a predetermined number of histories, for example, the most recent 7 records. Further, the notification information may be divided into categories that can be confirmed by the worker and categories that cannot be confirmed.

In the meter tap 82, each item of anti-theft, day/night mode, luminance adjustment, clock, language and camera display can be selected.

Moreover, in the PF tab 83, each item of yield measurement history, work start, fuel consumption amount reset, grain weight warning, yield sensor 0-point correction, and protein display can be selected as demonstrated below.

In the item "quantity measurement history", the most recently erased grain weight and dry weight are displayed. Even if the quantity measurement is reset, the quantity measurement before the reset can be confirmed in the quantity measurement history.

In the item "work start", the worker can determine whether or not to reset the integrated values of food and quantity. It is possible to determine, for example, for each package, at an arbitrary timing, that the integrated value of taste and quantity is reset, and measurement of the integrated value of taste and quantity is newly started.

In the item "Fuel Consumption Reset", the worker can determine whether or not to reset the fuel consumption amount. It is possible to determine, for example, every day at an arbitrary timing to reset the fuel consumption amount and start measurement of the fuel consumption amount anew.

In the item "grain weight warning", a worker can decide whether to display a warning when the threshold value of a grain weight and this threshold value are exceeded.

In the item "0-point correction of yield sensor", the worker can determine whether or not to correct the 0-point of the yield sensors for detecting the yield of rice, that is, the weight sensor 5b and the level sensor 5c.

In the item "protein display", the operator can change the moisture conversion value when performing the moisture conversion display while being able to switch between the dry standard display and the moisture conversion display. Further, in the PF tab 83 of Fig. 9, a state in which the item "protein display" is selected is shown.

The moisture and protein content of the rice stored in the reservoir 5 is detected by the taste sensor 5a, but when displaying the protein content, in the dry standard display, the protein of the entire grain excluding moisture The content rate is displayed, and in the moisture conversion display, the content rate of protein of the whole grain including the moisture set arbitrarily is displayed.

In addition, when it is set to display a selection information image according to "taste/quantity (statistics)" in the arbitrary display area 53a on the screen portion 34, "average protein..." is an item. … (%)”, “Protein… … The value of "(%)" is calculated and displayed depending on the selection of dry standard display or moisture conversion display.

By the way, about the item "quantity measurement history", "work start", "fuel consumption amount reset", and "grain weight warning" in the PF tab 83, there is a case where you want to display it every now and then during harvesting work. However, the PF tap 83 first shifts to the setting mode 80 by briefly pressing the setting button 38f to display the work tap 81, and then displays the meter tap by briefly pressing the right button 38d. (82) is barely displayed.

Since such multiple operations are cumbersome, when a long press of the set button 38e is accepted by the operation input unit 44, the screen control unit 41 displays information, not as a confirmation instruction such as a short press of the operation. It is processed as an instruction for transition from mode 70 to specific mode 84. That is, the screen control unit 41 performs a long press, which is a specific operation different from a short press, which is a normal operation, on the confirmation button 38e, and causes the screen unit 34 to display a specific specific operation that cannot be pressed by a short press. It is structured so that display by the specific mode 84 which is a display is made.

In the PF tab 85 in the specific mode 84, as shown in Fig. 20, among the six items displayed on the PF tab 83 in the setting mode 80, "quantity measurement history", "work Only four items of "start", "fuel consumption reset", and "grain weight warning" are displayed.

In the specific mode 84, if a long press of the set button 38e is accepted by the operation input unit 44, the screen control unit 41 ends the specific mode 84, and displays information on the screen unit 34. (70) is displayed.

In addition, in the PF tab 85 in the specific mode 84, four items of "quantity measurement history", "work start", "fuel consumption reset", and "grain weight alarm" are displayed in advance. The configuration is not limited, and the configuration may be such that the operator can arbitrarily set the items to be displayed on the PF tab 85. At that time, the items that can be set are not limited to the items in the PF tab 83, but may be configured to be selectable from each item in the work tab 81 and the meter tab 82. In that case, the display control device 40 may be configured to be able to store settings of items to be displayed on the PF tab 85 in the specific mode 84 for each user.

In this embodiment, the combine 1 is a sensor 5a (see Fig. 4) for detecting the moisture and protein content of rice, a weight sensor capable of detecting the weight of rice stored in the reservoir 5 ( 5b) (see Fig. 4), the screen control unit 41 displays the PF tab 83 in the setting mode 80. In the case where the combine 1 has a structure not provided with the taste sensor 5a or the weight sensor 5b, the display control device 40 does not display the PF tap 83 in the setting mode 80. At this time, the display control device 40 is configured to widen the width of the work tap 81 and the meter tap 82 compared to when they are displayed along with the PF tap 83.
