Document Type and Number:
Japanese Patent JP7036093
Kind Code:
B2
Abstract:
To provide a shape measurement device, shape measurement method, steel sheet shape correction device, steel sheet shape correction method, steel sheet manufacturing device, and steel sheet manufacturing method that include a laser scan type laser distance meter having an inexpensive dust-proof mechanism enabling an optical system to be protected from dust without lowering measurement accuracy.SOLUTION: A shape measurement device 8 comprises a laser distance meter 20 that measures a distance to a detection point P on a measurement object S by laser light 23. The laser distance meter 20 comprises: a laser light emitting unit 21 and a laser light reception unit 22; a reflection mirror 25; a revolving platform 26 that supports the laser light emitting unit 21, the laser light reception unit 22, and the reflection mirror 25 and, in measuring, forms a gap 34 through which the laser light 23 radiated from the reflection mirror 25 and the laser light 23 reflected from the detection point P pass; and a dust-proof mechanism 50 that includes a wall part 51 caulking the gap 34 when the revolving platform 26 is located at a prescribed revolution angle in a measurement standby state.SELECTED DRAWING: Figure 10
