Present position display device
First Claim
1. A present position display device adapted to be mounted in a vehicle and comprising:
- (a) a head member having light-emitting indication means;
(b) an elongated carriage mounting said head member;
(c) first driving means for moving said head member in an Y-axis direction coinciding with the longitudinal direction of said carriage;
(d) holding means mounting said carriage;
(e) second driving means for driving said carriage on said holding means in an X-axis direction perpendicular to said Y-axis direction;
(f) third means for driving said second driving means and said first driving means in a manner corresponding to the travel of said vehicle;
(g) a sheet pack disposed above and close to a plane where said head member moves;
(h) an indicating window means provided in said sheet pack for rendering said light emitting indication means visible to an operator of said vehicle;
(i) a plurality of maps in said sheet pack each consisting of a transparent or translucent flexible member on which map information is printed;
(j) means for selectively transferring one of said maps to said indicating window means; and
(k) accommodating means within said sheet pack for winding and accommodating maps other than the map positioned in alignment with said indicatint window means.

Abstract
A present position display device suitable for use on automobiles or the like vehicles, having a head member provided with a light-emitting element and a light-receiving element; a driving mechanism for driving the head member in the directions of an X and Y-axes; a mechanism for rotationally driving the driving mechanism; a sheet pack detachably mounted in the vicinity of and in parallel with the plane of movement of the head member; and a map transferrably disposed in the sheet pack; whereby the present position of the vehicle is indicated by the light coming from the light-emitting element on the map. Means are provided to read codes of specific positions marked on the map and to make an indication of the specific position as desired.

12. A present position display device adapted to be mounted in a vehicle and comprising:
-
(a) a head member provided with a light-emitting element for emitting light and a light-receiving element; (b) means for moving said head member within a plane and in a manner corresponding to the movement of said vehicle; (c) means including a half mirror disposed in a plane parallel to and above the plane of movement of said head member so as to cover the region of movement of said head member for reflecting a part of the light element so as to transmit a part of the light from said light emitting element to make it visible; and (d) means including a map disposed between said head member and said half mirror and consisting of a light permeable sheet, said map having map information printed by a visible material, for enabling said light-receiving element to receive information as differences in intensity of said light. - View Dependent Claims (13, 14)

- 15. A display device for indicating the position of a vehicle, including means for holding a map in a viewing position within said vehicle, said map being formed from a material allowing light to pass therethrough and having opaque portions defining information on said map, means including a half-mirror mounted over the portions of said map viewed by the operator of said vehicle for enabling a portion of light directed from behind said map to pass through to said operator while reflecting a portion of said light back behind said map, a head member mounted for movement behind said map and carrying means for emitting light towards said map and means for receiving reflected light to produce a signal corresponding to information on said map, and means connected to said head member for moving it behind said map as a function of the movement of said vehicle.

18. A display device for indicating the position of a vehicle, including means for holding a plurality of maps attached together serially in a viewing position within said vehicle, said maps each being formed from a material allowing light to pass therethrough and having opaque portions defining information on the respective maps;
- said holding means forming a unitary container for said maps and including a central window portion for viewing a map therebelow, means on respective sides of said control window for storing maps and drive means for advancing said maps serially beneath said central window;
scan means including a head member mounted movably beneath said container and carrying means for emitting light through said central window portion and said map therebelow for illuminating selected areas of said map, said scan means including means for moving said head member beneath said central window portion as a function of movement of said vehicle. - View Dependent Claims (19, 20, 21, 22, 23)
