Route information input apparatus and method thereof
First Claim
1. An apparatus for inputting route information necessary to specify a route from one node element serving as a starting point to another node element serving as a terminal, comprising:
- (a) display means having a display screen for furnishing a user with circumstances so that said user can input route information;
(b) pointing means operated by said user to designate a position on said display screen;
(c) data processing means responsive to an input operation of said pointing means to execute a data processing in accordance with a program prepared in advance to thereby change a displayed content on said display screen;
(d) first file means for storing therein positional information necessary to draw a line diagram for designating a route on said display screen with respect to major node elements of a plurality of node elements in respective lines truly existing on an actual line map; and
(e) second file means for storing therein code information necessary to display a table of node elements on said display screen with respect to a plurality of node elements in respective lines including node elements omitted from said line diagram, whereinsaid data processing means comprises;
first means for displaying on a first area of said display screen a line diagram that is presented in a simplified form by partly omitting truly existing node elements on the basis of the positional information stored in said first file means;
second means for registering a line of interest designated by said user with said pointing means;
third means for selectively retrieving code information of a group of node elements located on said line of interest and for displaying on a second area of said display screen said group of node elements omitted from said line diagram displayed on said first area in the form of a table; and
fourth means for storing therein elements displayed within said first or second area selected by said pointing means as input information specifying a part of a route.

Abstract
A route information input apparatus for specifying a route from an entraining station to an arrival station including a pointing device operated by the user to designate a position on a display screen and a data processing apparatus for executing a data processing in accordance with a program prepared in advance each time the user operates the pointing device to thereby change a displayed content on the display screen. On the basis of positional informations of major stations stored in a first file, a line diagram presented in the simplified form in which truly existing stations are partly omitted and in which the major stations are connected by means of line segments is displayed on a first area of the display screen. A group of station name data omitted from the line diagram displayed on the first area are selectively displayed on a second area of the display screen in the form of a table. Then, stations or lines selected from the first area or from the second area by the pointing device are sequentially stored as route specifying informations. As the route is specified, a display form is sequentially changed so that a route portion that was already specified and a line portion that can be selected next can be distinguished from other line portions with ease in the line diagram displayed in the second area.

7. A route information input method for specifying a route from one node element serving as a starting point to another node element serving as a terminal in a terminal apparatus including a display screen and a pointing device, comprising the steps of:
-
(a) displaying on a first area of said display screen a line diagram presented in a simplified form where truly existing node elements are partly omitted and which is composed of a plurality of node elements and a line segment connecting said note elements; (b) designating one node element or line segment in said line diagram by said pointing device; (c) changing a display form so that the line diagram including the node element or line segment designated by said pointing device can be distinguished from other lines in said line diagram; (d) displaying on a second area of said display screen a group of node elements omitted from said line diagram displayed on said first area in the form of a table with respect to a line specified last in route elements that were already specified; and (e) designating one node element displayed on said table by said pointing device, wherein route specifying elements selected on said first or second area by said pointing device are stored as route input information in a sequential order of time series.

8. An apparatus for inputting route information necessary to specify a route from one node element serving as a starting point to another node element serving as a terminal, comprising:
-
(a) display means having a display screen,for furnishing a user with circumstances so that said user can input route information; (b) pointing means operated by said user to designate a position on said display screen; (c) data processing means responsive to an input operation of said pointing means to execute data processing in accordance with a program prepared in advance to thereby change a displayed content on said display screen; (d) first file means for storing therein positional information necessary to draw a line diagram for designating a route on said display screen with respect to major node elements of a plurality of node elements in respective lines truly existing on an actual line map; and (e) second file means for storing therein code information necessary to display a table of node elements on said display screen with respect to a plurality of node elements in respective lines including node elements omitted from said line diagram, wherein said data processing means comprises; first means for displaying on a first area of said display screen a line diagram that is presented in a simplified form by partly omitting truly existing node elements on the basis of the positional information stored in said first file means, wherein the line diagram displayed on said first area of said display screen is composed of a plurality of lines connected in a crossing or diverging fashion, and said first means includes means being responsive to a particular operation of the route information done by said pointing means to partly change the state of said line diagram displayed on said first area so that route components that were already specified and a line to be selected next can be visually distinguished from other lines.
