Abstract

PURPOSE:To simplify the handling operation, by setting turnably and fixably a curved surface mirror which receives laser light. CONSTITUTION:A bracket 7 is fixed to one end of a laser power source part 5 and is erected, and a curved surface mirror 9 is fixed to a channel-shaped frame rod 8 so that the curved surface of the mirror 9 faces laser light 2, and the frame rod 8 is supported pivotally in the upper part of the bracket 7 turnably and fixably. The laser light passes through a collimator incorporated in the head part of a laser tube 6 to obtain a condensed beam at the focus. The fanshaped beam reflected from the mirror 10 is moved from the horizontal direction to the zenith direction by turning of the frame rod 8. The fan-shaped beam is shown as one line having >=90 deg. opening angle, and a reference line is set easily in case of consturction of various kinds of buildings.

In 1), a bracket (8) is fixed and erected at one end of the laser power supply section (5) (tripod section omitted), and the curved surface of the curved mirror (9) is attached to the U-shaped frame rod 181 to transmit the laser beam (2). The frame rods (8) are rotatably and fixedly supported on the upper part of the bracket (1).

), and by rotating the frame rod (9), the fan-shaped beam (12) reflected from the curved mirror (10) can be moved from the horizon direction to the zenith direction.

．． 5 mm or less, and the smaller the radius of curvature of the curved mirror (10), the sharper the expansion angle of the fan-shaped beam (12) can be. If the design is such that the reflected beam of t2) does not collide with the laser tube (6), the angle can be expanded to 180 degrees.

Also, the fan-shaped beam (12) is reflected by the curved mirror (10).
) is displayed as a single straight line with an expansion angle greater than or equal to (a) degrees, making it easy to set reference lines when constructing various structures. The reference line can be freely set from the horizon direction to the zenith direction by rotating the frame rod (9) by a desired angle.
