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.
