Coordinate-data input device for CRT display having cursor travel control means
First Claim
1. A coordinate-data input device for moving a cursor on a screen of a cathode-ray tube display which is controlled by a controller, comprising:
- a planar board having a top surface;
a manually movable unit movable on the top surface of said planar board in X-axis and Y-axis directions, said manually movable unit including detector means for detecting amounts of movement of said manually movable unit in said X-axis and Y-axis directions on said planar board;
magnification selector means for selecting one of a plurality of values of magnification; and
processing means electrically connected to said controller of the cathode-ray tube display, said detector means and said magnification selector means, for obtaining distances of movement of said cursor on the screen of said display, by multiplying the detected amounts of movement of the manually movable means by said one value of magnification selected by said selector means.

Abstract
An apparatus for entering coordinate data for moving a cursor ona screen of a CRT display in response to movements of a manually movable unit on a planar board, comprising a detecting device disposed on the manually movable unit to detect amounts of movement of the manually movable unit in X- and Y-axis directions on the planar board, a magnification selector for selecting one of plural values of magnification of the detected amounts of movement of the movable unit, and a data processor for obtaining distances of movements of the cursor on the display screen, by multiplying the detected amounts of movement of the movable unit by the selected value of magnification.

9. A coordinate-date input device for moving a cursor on a screen of a cathode-ray tube display which is controlled by a controller, comprising:
-
a planar board having a top surface; a manually movable unit movable on the top surface of said planar board in X-axis and Y-axis directions, said manually movable unit including detector means for detecting amounts of movement of said manually movable unit in said X-axis and Y-axis directions on said planar board; magnification selector means for selecting one of a plurality of magnification values of the input device; a selector switch operable between a first position and a second position; and processing means electrically connected to said controller of the cathode-ray tube display, said detector means and said magnification selector means, for obtaining distances of movement of said cursor on the screen of said display, by multiplying the detected amounts of movement of the manually movable means by the selected magnification value when said selector switch is placed in said first position, and by dividing said detected amounts of movements by said selected magnification value when said selector switch is placed in said second position. - View Dependent Claims (10, 11, 12)
