Claims

[Scope of utility model registration request]

A target signal generation device that generates a target signal indicating the distance and direction of a target at an arbitrary position, a target position calculation device that calculates the position from the target signal, and a display position that converts the target position to a position on a display screen. a calculation device, a display range inside/outside discrimination device that determines whether the target is outside the display range based on the display position signal, a target marker lighting device that lights up a marker on a display screen for a target that is within the display range, and a target marker lighting device that lights up a marker on a display screen for a target that is within the display range; A target display device characterized by comprising an auxiliary display screen marker lighting device that lights up a marker on an auxiliary display screen provided around a display screen based on the direction in a certain case.
