Patent ID: 7773073

Claim:
An operation equipment that operates by selecting either of a plurality of indication keys by a cursor with using an operation screen arranged the plurality of indication keys assigned different operations, the operation equipment comprises: an inclination angle detector that detects inclination of an equipment and outputs an posture signal; a cursor controller that makes the cursor move by specifying either of the plurality of indication keys based on the posture signal from the inclination angle detector; a rotation angle calculator that computes rotation angles of an X-axis and a Y-axis which are parallel to a main surface part and perpendicularly intersect mutually based on the posture signal from the inclination angle detector as an X-axis rotation angle and a Y-axis rotation angle, respectively; a cell information memory that memorizes a cell information provided with a plurality of cells; and a conversion table memory that memorizes a conversion table that associates each cell of the cell information memorized by the cell information memory with the indication key; is provided, wherein the cursor controller specifies either of the plurality of indication keys based on the X-axis rotation angle and the Y-axis rotation angle that are computed by the rotation angle calculator and makes the cursor move; and the cursor controller specifies the indication key associated with the current cell by using the conversion table and moves the cursor while specifying one cell in the cell information as a current cell based on the X-axis rotation angle and the Y-axis rotation angle which are computed by the rotation angle calculator.
