2. Description of the Related Art Conventionally, measuring instruments such as a shape measuring instrument and a surface roughness measuring instrument for displaying measured results in a graph on a display screen are known. For example, in the case of a surface roughness shape measuring instrument, as shown in FIG. 7, the shape (cross-sectional curve) of the surface of the measured object with respect to the measurement direction is displayed as a continuous graph. Conventionally, when reading the amplitude value of a desired measurement position of the cross-sectional curve, the cursor is moved to a reading position by pressing a cursor movement switch (←, →). When connected to a computer such as a personal computer, a mouse is used to move the cursor by dragging the mouse cursor to the tag displayed on the cursor.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a measurement data processing device which can easily set a cursor on a screen to a desired position.

[0005]
