Document Type and Number:
Japanese Patent JP2775169
Kind Code:
B2
Abstract:
PURPOSE:To perform accurately positioning of a rest body by displaying accurately the position of a standard point determined in the test body on the surface of the test body by means of a plurality of projections from specified directions. CONSTITUTION:An operator reads a coordinate (y) of a center of gravity 33 from a computer 23. A table 21 is moved in the longer direction (the direction (y)) in such a way that the position of the center of gravity 33 is equal to the position in the direction (y) of projectors 10, 11 and 12 by means of a motor 60 and a position detecting sensor 61 by operating an operator console 20 and the position is controlled. A positional relation between a test body 31 placed on the table and projectors 10, 11 and 12 are controlled by this action. The projectors 10, 11 and 12 are turned on by operating an ON/OFF switch of a controller 13 or a remote controller 29. Extensions of these light beams cross the center of gravity 33 in the concerned region 32 of the test body 31. The position of the center of gravity 33 in the concerned region 32 is accurately displayed thereby on the surface of the test body 31 by means of the light beams from both sides and the upper side.
