Claims

[Scope of utility model registration request]

(1) A horizontal guide rail arranged in the horizontal direction of a flat plate, one end of which engages with the horizontal guide rail and is movable along the horizontal guide rail in a direction substantially perpendicular to the horizontal guide rail. A rotated sphere comprising a vertical guide rail having a guide rail, an arm having one end engaged with the vertical guide rail and movable along the vertical guide rail, and disposed so as to be freely movable on a flat plate. , a first driven roller that is in contact with the rotated sphere and rotates by the rotational force of the rotated sphere, and a second driven roller that is rotated by the rotated sphere and whose axial direction is substantially perpendicular to the axial direction of the first driven roller. a driven roller; and the first driven roller.
2. The first roller detects the amount of rotation of the second driven roller, respectively.
, has an X-Y direction input device consisting of a second rotation amount detection means, this X-Y direction input device is fixed to the other end of the arm, and the X-Y direction input device is moved up and down on the flat plate. A coordinate reading device characterized by being movable left and right.

(2) A utility model registration request characterized in that the axial direction of at least one of the first and second driven rollers is parallel to at least one of the horizontal guide rail and the vertical guide rail. Coordinate reading device according to scope 1.

(3) A cursor displaying an input point is installed at the end of the X-Y direction input device, a coordinate origin is displayed on the flat plate, and the cursor can be moved to a position overlapping the coordinate origin. Utility model registration claim No. 1 characterized in that an X-Y direction input device is movably arranged on a flat plate.
) or (2).

(4) The coordinate reading device according to claim (3) of the utility model registration, characterized in that the coordinate origin is located at the upper left of the flat plate.

(5) Utility model registration claim 1, characterized in that the first and second rotation amount detection means are constituted by encoders.
