Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a device for displaying an arbitrary position of a moving body, and for example, to a device for detecting and displaying the current position of a moving automobile.

(Prior art) For example, in Japanese Patent Application Laid-Open No. 58-26214, etc., the departure point, destination, and positions of transit points, etc. are input in advance, and the direction of travel at each point is determined based on the input information. A display device has been proposed. In this conventional device, the driver unfolds an atlas, measures the positions of the departure point, destination, and waypoints, and inputs the measured positions into the navigation device from a keyboard.

Further, Japanese Patent Application Laid-open No. 110190/1983 has proposed a device in which a transparent display panel is placed on top of an atlas and the current location is displayed on the transparent panel.

(Problems to be Solved by the Invention) However, in conventional navigation devices, little consideration has been given to the keyboard for inputting information manually.

When a keyboard is placed on a transparent panel, the entire transparent panel must be handled in order to input measured positions, etc., making it extremely difficult to handle in a narrow automobile.

The present invention has been made to solve these problems, and its technical object is to facilitate the handling of a keyboard in a narrow automobile.

(Structure of the invention) (Means for solving the problem) The technical means taken to achieve the above-mentioned technical means is a map that is placed on a map and fixed to the outer periphery of a transparent plate. A mobile object display device comprising a display device that displays a current position on a map using a plurality of light emitting means, a display panel that displays a direction to a destination, and a keyboard for manually setting a registered point. The device, display panel, and keyboard are configured separately.

(Function) According to the above-mentioned technical means, since the keyboard is provided separately from the display device, only the keyboard needs to be handled when inputting the measured position, etc. Since there is no need to handle a large display device in a narrow car, the keyboard becomes easier to handle.
