Claims

[Scope of utility model registration request]

(1) A graphic that shows the passing range of the headlight main optical axis inspection and a symbol that shows the center position of the main optical axis are displayed as images on the CR'l' screen, and the symbols can be used to adjust the headlight position. In a display device for inspecting the main optical axis of a headlight that is displayed by moving the headlight to follow the direction, the headlight includes a setting device for setting coordinate data for specifying a shape indicating the passing range for each vehicle type, and A main optical axis measurement device that outputs a signal indicating the coordinates of the center position of the main optical axis of the headlight through image processing from the light irradiation pattern, a video RAM that stores image data and color information, and a manual inspection device for main optical axis inspection. The operated vehicle type selection switch and the coordinate data indicating the passing range of the vehicle to be inspected designated by the vehicle type selection switch among the coordinate data indicating the passing range of each vehicle inputted by the setting device are stored in the video RAM. a CRT controller for transmitting to the video RAM image data and color information for displaying an image of a symbol indicating the center position of the main optical axis based on the output signal of the main optical axis measuring device; a color CRT that displays the figures and symbols in color based on stored image data and color information;
A display device for inspecting the main optical axis of a headlight, characterized by comprising:

(2) The CRT controller changes the color of the symbol indicating the center position of the main optical axis of the headlight in the figure indicating the passing range displayed on the screen of the color CRT depending on whether or not there is a symbol indicating the center position of the main optical axis of the headlight. The display device for inspecting the main optical axis of a headlight as set forth in claim (1) of the utility model registration, characterized in that color information for identifying the difference is sent to the video RAM.
