<P>PROBLEM TO BE SOLVED: To provide a marking device capable of projecting a two-dimensional graphic at an appropriate position even when the horizontal placement of a casing is difficult. <P>SOLUTION: A marking device 1 is provided with: a projector 10 for projecting a marking graphic; a multi emission device 20 for emitting three laser beams LB1, LB2 and LB3 to horizontal rectangular two directions and down to a vertical direction; first and second inclination sensors 31 and 32; an imaging device 33; a casing 60 to which they are fixed; and a control device 50. The multi-emission device 20 is provided with: a free support member 23 for mounting an emission member 22 on the casing 60 such that its direction is variable; and a weight 29 for maintaining the direction of the emission member 22 from which the third laser beam LB3 is extended down to the vertical direction. The control device 50 is configured to correct the direction of a visible ray flux emitted from the projector 10 based on the position deviation value and rotational deviation angle of the third laser beam LB3 with respect to the reference mark of a placement face SF imaged by the imaging device 33 and the inclination of the projector 10 detected by the first and second inclination sensors 31 and 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
