The instrument section 3 02 is provided on the display surface 3 04, and includes a digital speed display section 05, an analog engine speed display section 3 06, and various alarm display sections 307. In the above-mentioned instrument section 302, as the information of the locomotive, speed, engine revolutions, and various kinds of information can be obtained. Although these information are collectively displayed on a 1 display section, for drivers, the information with a higher priority is conveyed in the information 'need to be designed to change its color or display method, etc., sometimes) ¾ # f ϋ 高. In order to obtain a rear field of view which is information at the rear of the vehicle body, in order to see the left and right rear-view mirrors 3 and 5 and 3, the line of sight must be shifted to the left and right. If the rear field of vision can be confirmed at the same position as the instrument section 302 1238789 (2), the movement of the line of sight can be reduced, and information can be easily obtained. And 'can be obtained as other information at the same position as the instrument section 302, such as' various information of the engine, information about navigation devices, traffic information, etc.', and if the priority order can be clearly displayed, a lot of information can be obtained instantly Information. [Summary of the Invention] A problem to be solved by the stomach] The first invention is a locomotive provided with a display device having a display section for displaying information such as driving status on the front of the vehicle body, and is characterized in that the display device S ' The lens surface of the display unit is a type in which the meter @ case, which is different from that of the display unit, is protruded toward the driver side, and is arranged so as to extend into the lens surface. Closer to the driver ’s side. If information with a higher priority is displayed on the display section closer to the driver ’s side, the driver does not need to design the color or display method specifically, so that the driver can easily recognize the concentrated information. The second invention uses a rear view screen 'for monitoring the rear of the locomotive as the display portion. The display section is a rear view screen for monitoring the rear of the locomotive. Compared with the case of using a rearview mirror, it can reduce the movement of the line of sight, and can obtain the rear view of the locomotive together with other information. The third invention is a speedometer in which the meter section is formed. If the instrument department is made into a speedometer, it can be obtained together with other information: to speed -5- 1238789 (3) information. According to a fourth invention, an analogue type is used for the speedometer. A speed number is displayed inside and along the outer edge of the speedometer, and a tachometer with an appearance smaller than the analogue type of the speedometer is placed on the speedometer. In addition to the speed information, you can get the engine revolution information together with other information. The fifth invention is "the upper part of the leg shield covering the front of the driver's feet". The rear view screen for obtaining information behind the vehicle body is set to protrude upward, and the meter is partially overlapped. The meter section is arranged on the upper part of the rear view screen. The meter section is composed of an analogue speedometer and an analogue tachometer arranged inside the speedometer and having an analogous shape similar to the speedometer. The upper space of the leg shield can be effectively used to centrally arrange the rear view screen and the instrument section, and a large amount of information can be easily and instantly obtained. A sixth invention is a display unit having a function as an engine monitor for displaying an operating state of an engine when the locomotive is stopped. The display unit functions as an engine monitor and can obtain a large amount of information with one display unit. [Effects of the Invention] According to the first invention, the display device is configured to protrude into the lens surface with respect to the lens surface of the display portion by projecting a housing of the instrument portion different from the individual toward the driver's side. The display section of the housing is arranged closer to the driver than the -6-1238789 (4) display section, so if the higher priority information is displayed on the display section closer to the driver, the color or display method need not be displayed. The special design allows the driver to easily recognize the concentrated information. The second invention uses a rear-view screen to monitor the rear of the locomotive as a display. To confirm the rear situation, compared with the case of using the rearview mirror, the sight line movement can be reduced, and the rear view of the locomotive can be obtained easily and quickly together with other information. According to the third invention, the speed information can be obtained together with other information by making the meter section a speedometer. According to a fourth invention, an analogue type is used for the speedometer. A speed number is displayed inside and along the outer edge of the speedometer, and a tachometer with an appearance smaller than the analogue type of the speedometer is placed on the speedometer. The inside of the outer edge of the engine, so in addition to the speed information, you can get engine revolution information together with other information. According to a fifth invention, a rear view screen for obtaining information behind the vehicle body is provided on the upper part of the leg shield covering the front of the driver's feet so as to protrude upward, and the meter is partially overlapped. The meter section is arranged on the upper part of the rear view screen. The meter section is composed of an analog speedometer and an analog tachometer which is arranged inside the speedometer and has a shape similar to the speedometer. The upper space of the leg shield can be effectively used to centrally arrange the rear view screen and the instrument section, and a large amount of information can be easily and instantly obtained. -7- 1238789 (5) In the sixth invention, the display unit has a function as an engine monitor for displaying the operating state of the engine when the locomotive is stopped, so that a large amount of information can be efficiently obtained by one display unit.
