PURPOSE: A correcting device for a slab measuring device is provided to move a plurality of reflectors by a set distance, compares the moving distance of the reflectors with the values measured by a slab measuring device, and compensate the slab measuring device according to the comparison results. CONSTITUTION: A correcting device for a slab measuring device comprises a frame part(20), a first driving part(50), a second driving part(60), a third driving part(70), and a control part(100). The frame part is moved along a roller member(9). The first driving part is mounted on the frame part and moves a first reflector(34) in a first direction that the frame part is moved. The second driving part moves a second reflector(36) in a second direction perpendicular to the first direction. The third driving part rotates the second reflector and a third reflector(40) in a direction inclined to the second direction.
