Claims

[Scope of utility model registration request]

A slide head is attached to a column erected on the side of the bed so as to be able to move up and down, and a cross-movement table movable in orthogonal directions in a horizontal plane is installed on the bed. An alignment line is engraved in a direction perpendicular to the direction of movement, and a subject is placed thereon, while a bracket is attached to a horizontal mount plate attached to the slide head so as to be rotatable and fixed in a horizontal plane. A vertical mount plate is tiltably supported by the bracket via a horizontal hinge pin, and an adjustment bolt is interposed between the vertical mount plate and the bracket to tilt and fix the vertical mount plate. The vertical mount plate is provided with a light cutting mechanism in which a projector that obliquely projects slit light onto the subject and an imaging device that captures a cross-sectional image using the slit light are arranged axially symmetrically. A shape measuring device using an optical cutting method, characterized in that a method measuring instrument body is installed.
