Claims

[Scope of Claim for Utility Model Registration] A machine base, a movable rail provided so as to be movable in the longitudinal direction of the machine base, and a lamp and a lamp provided on the movable rail so that its position can be freely adjusted by a light source mechanism fixing mechanism. a light source mechanism made of a light condensing mirror and having an optical axis parallel to the moving direction of the movable rail; and a light condensing lens fixing mechanism to the movable rail so as to be located on the optical axis of the light source mechanism in front of the light source mechanism. a light-condensing lens whose position can be adjusted freely; a projection lens fixed to the machine stand on the optical axis of the light source mechanism and in front of the light-condensing lens; and the light source mechanism and the light-condensing lens. A variable diaphragm mechanism having an aperture diameter adjustment handle fixed to the machine base so as to be located on the optical axis of the light source mechanism between the variable diaphragm mechanism and the lens; A link mechanism connects the two so that the movable rail moves in response to the movement, and the link mechanism is configured to move the aperture diameter adjusting handle of the variable diaphragm mechanism in a direction to reduce the aperture diameter. The movable rail is moved so that the light source mechanism approaches the variable diaphragm mechanism and the condensing lens moves away from the variable diaphragm mechanism, and the aperture diameter adjustment handle of the variable diaphragm mechanism is moved to adjust the aperture diameter. When moving in the direction of increasing the aperture, the movable rail is moved so that the light source mechanism moves away from the variable aperture mechanism and the condensing lens moves in a direction toward the variable aperture mechanism. A follow-up spot irradiation device.
