PROBLEM TO BE SOLVED: To mount a hologram on a mounting position horizontally by grasping the hologram from its side surface with first, second fingers in the state that the upper surface of the hologram is abutted horizontally on an abutment part with a hologram grasp hand horizontally moving, vertically moving and horizontally rotating the hologram. SOLUTION: The hologram grasp hand for moving the hologram in the X axial, Y axial directions and rotating in the biaxial direction abuts horizontally on the upper surface of the hologram with the abutment parts 47, 48 of respective lower surfaces of abutment plates 45, 46. In such a state, the hologram is grasped from its side surfaces with V grooves 43, 44 of an immovable and movable fingers 35, 36 moving integrally with she substrate 34 of the hologram grasp hand and in the direction of the arrow 39. The V grooves 43, 44 are provided on the immovable and movable fingers 35, 36 at respective opening angles 90 deg., and hold the movable finger 36 with linear sliders 37, 38 to be pushed out with a piston 42. Thus, the hologram is fixed to the mounting position while horizontally keeping it. |
