As shown in FIGS. 2 and 3, the housing 31 is formed by, for example, resin injection molding, and has a horizontally long rectangular shape with rounded corners. The surface is formed in a shape that rises while being inclined toward the front side with respect to the surface of the display section 32 . With such a shape, the operating portion 33 side can be brought closer to the operator, so that the operator's finger can easily reach the operator and the operability is good.

The thickness of the housing 31 at least on the side of the operation unit 33 is such that it can be grasped by a worker's hand. ing. When operating the operation unit 33 with the thumb, the worker can support the housing 31 by wrapping his/her fingers other than the thumb around the rear surface of the housing 31 . Therefore, reliable operation is possible even in a situation where the machine body shakes, such as when the combine 1 is running.

The housing 31 is configured in a shape in which a lower corner on the operation unit 33 side is cut off when viewed from the front. Therefore, when the worker gets on and off or sits down, the worker's legs, especially the knees, are less likely to hit. Therefore, it is difficult for the operator to get in and out of the machine, and the operator can take a stable posture with his legs slightly spread when he is seated. Further, when the operator holds the operation unit 33, the operation tool 38, which is provided in the operation unit 33 and will be described later, can be easily reached by the operator's fingers, so the operability is good.

The housing 31 is provided with a panel body 31d on the rear surface of the rectangular opening and the elongated opening when viewed from the front.

In this embodiment, the screen unit 34 is composed of a color liquid crystal monitor having a horizontally long rectangular display area. A color liquid crystal monitor preferably has a size of about 7 inches from the viewpoint of visibility, space saving, price, and the like.

The screen unit 34 is controlled by the display control device 40 and is capable of displaying at least an information image corresponding to various information relating to the machine body of the combine harvester 1 or the setting or state of the work performed by the combine harvester 1 .

The panel body 31d is made of a resinous flat plate, and is configured to have light transmittance at a portion corresponding to the display area of the screen portion 34. As shown in FIG.

When viewed from the front of the housing 31, between the screen portion 34 and the operation portion 33, there is a space between the screen portion 34 and the work load level of the combine harvester 1, in this embodiment, the load representing the load state of the engine. A display unit 35 is provided.

The state of the engine load as the work load level of the combine harvester 1 is information of high importance from the viewpoint of continuation of appropriate work, and such information of high importance is displayed separately from the screen section 34. Visibility is enhanced by displaying the load display section 35 provided closer to the worker than the section 32 separately from other various information. In addition, operability is enhanced by arranging the operation unit 33 near the operator.

If an image representing the level of the workload is displayed in the same display area of the screen section 34, a program for representing the level of the workload will be required, or the space for displaying other information images will be reduced. Therefore, in order to improve visibility, the screen section 34 having a larger display area is required. A color LCD monitor with a larger display area requires a larger housing and is more expensive. By separating the screen part 34 and the load display part 35, the screen part 34 having a large display area and a program for displaying the work load level are not required.

The panel body 31d has light transmittance at the portions where the segments 35a to 35e are arranged, and the portions corresponding to the segments 35a to 35c are colored green, the portions corresponding to the segments 35d are colored orange, and the segments 35e are colored. are colored in red.

Each LED element is light-emission-controlled from segment 35a to segment 35e according to the level of the workload. increases and all segments 35a-35e are illuminated at the highest level of workload.

The load display unit 35 has segments 35a to 35e arranged vertically along one side on the right side of the screen unit 34. When the work load level is the highest, the uppermost segment 35e is lit. is configured to Therefore, the higher the workload, the easier it is to attract the worker's attention.

The rectangular opening 31a and the elongated opening 31b have the same length in the vertical direction, and the load display section 35 has segments 35a to 35e arranged over substantially the same length as the elongated opening 31b in the vertical direction. It is Therefore, the load display portion 35 is longer than the right side of the screen portion 34, and is the length of the rectangular opening 31a in the vertical direction, i. It has the same length as length.

A sign 37c that lights up when there is an abnormality, a sign 37d that lights up when an abnormality occurs in the engine, a sign 37e that lights up when the parking brake is applied, and a sign 37e that lights up when the remaining amount of fuel is low. A sign 37f, a sign 37g that lights up when there is an abnormality in the urea water quality, a sign 37h that lights up when an abnormality occurs in the urea SCR system, a sign 37i that lights up in sync with the lighting of the work light, and a blinker lamp 19. There is provided a sign 37j that blinks in synchronism with the blinking of .

The panel body 31d has optical transparency at the locations where the markers 37a to 37j are arranged, and the locations corresponding to the markers 37a and 37j are colored green, and the markers 37b, 37c, 37d, 37e, and 37h are colored green. The corresponding portions are colored red, the portions corresponding to the markers 37f are colored yellow, and the portions corresponding to the markers 37i are colored blue.

As shown in FIG. 3, on the substrate 36, a plurality of white LED elements 37z are mounted as light emitting portions at positions corresponding to the signs 37a to 37j. Light emission of each LED element is controlled in response to occurrence of an event corresponding to each of the signs 37a to 37j, so that each of the signs 37a to 37j lights up or blinks.

In this manner, the housing 31 can be made compact even though the sign placement portion 37 is provided separately from the screen portion 34 . By arranging the screen portion 34, the load display portion 35, and the sign placement portion 37 in a rectangular shape as a whole, the design of the display portion 32 is enhanced.

The operation unit 33 is located on the right side of the display unit 32 and is used by the operator to operate information images displayed on the screen unit 34. The operation unit 33 is provided with an operation tool 38 for receiving operations by the operator. The operation tool 38 is arranged on the upper end side of the center in the vertical direction when the housing 31 is viewed from the front. Since the operation tool 38 is arranged at a position close to the operator and can be easily reached by a finger, the operability is good.

The operation tool 38 includes a group of operation switches 38a to 38d that enable scrolling of information images displayed on at least the screen section 34. Specifically, an upper switch 38a, a left switch 38b, a lower switch 38c, a right switch 38d, a screen An information display mode 70 in which an information image corresponding to various information is displayed on the screen portion 34 and a confirmation switch 38e for confirming the contents displayed on the screen portion 34, and a setting mode in which a setting screen regarding display on the screen portion 34 is displayed. 80 (see FIG. 8).

The setting switch 38f is arranged closer to the display section 32 than the group of operation switches 38a to 38d, specifically, to the lower left of the left switch 38b and the lower switch 38c. The setting switch 38f is operated less frequently than the operation switch group 38a-38d. Therefore, by arranging the setting switch 38f at a position farther from the group of operation switches 38a to 38d, the possibility of erroneously operating the setting switch 38f is reduced.

The operation tool 38 is arranged inside the trapezoidal opening 31c, and the operation surface of the operation switch groups 38a to 38d and the operation surface of the setting switch 38f are arranged at positions recessed from the surface of the housing 31. .
