Abstract
The present invention relates to a coordinate input device that enables coordinates to be input onto the display screens of various types of terminals, such as portable information terminals, through an operation of scrubbing or rubbing two opposite flat plates that are so small that they can be held between two fingers such as the thumb and the index finger or between three fingers, so that it can be easily and stably used even in an extremely restrictive environment such as a narrow space or a mobile situation. The finger mouse-type coordinate input device according to the present invention can detect a signal corresponding to the vertical movement or lateral rotation of two opposite flat plates in response to the application of a drive signal.

28. A coordinate input device, comprising:
-
a parallel resistor board configured to have parallel resistors oriented upward or downward; a cross conductor board disposed in contact with the resistors over or under the parallel resistor board; and a lever configured such that a protrusion sequentially passes through central holes of the parallel resistor board and the cross conductor board and is engaged with the parallel resistor board and the cross conductor board, and configured to have a predetermined flat surface. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

36. A coordinate input device comprising:
-
a lower plate combined with a circuit board including an optical sensor; and an upper plate configured such that a protrusion is inserted into a guide recess or hole and is moved vertically or rotated laterally; wherein the optical sensor detects a signal corresponding to a moving location of the upper plate while radiating light onto a lower surface of the upper plate through a through hole of the lower plate. - View Dependent Claims (37, 38, 39, 40)
