[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 shows an appearance of a first embodiment of the present invention, and FIG. 2 shows a cross section of the first embodiment taken along line # 2 as viewed in the direction of the arrow. In these figures, arms 16 and 18 are formed to protrude from longitudinal ends of a pendulum weight 14 in which laser pointers 10 and 12 are built. The optical axes of the laser pointers 10 and 12 are coincident, and are in ± X directions. The optical axis and the arms 16 and 18 are also orthogonal to each other, and are in the ± Y direction. The arms 16 and 18 are rotatably supported by bearings 24 and 26 at the ends of the sleeves 20 and 22. The sleeves 20 and 22 extend in parallel from a support table 28, and the support table 28 is rotatably supported on a base 30 by a bearing 32. The rotation axes of the arms 16 and 18 by the bearings 24 and 26 and the rotation axes of the sleeves 20 and 22 by the bearing 32 are orthogonal to each other.

The laser pointers 10 and 12 are provided with a semiconductor laser element and a drive power supply, and press the exposed portions to output parallel light of a visible laser. I have. In the illustrated example, two laser pointers are provided to output laser beams vertically and vertically, but one may be omitted if not necessary. The pendulum weight 14, the sleeves 20, 22 and the support 28 are made of a metal material such as stainless steel, for example, and the base 30 is made of a magnet. As the bearings 24, 26 and 32, general bearings such as ball bearings can be used. Since a magnet is used for the base 30, a material that is not affected by magnetism is used as a material of each part.

As described above, the pendulum weight 14 is formed longitudinally along the shape of the laser pointers 10 and 12 built in the center, and the longitudinal direction is the laser light emission of the laser pointers 10 and 12. The direction is the optical axis. A pair of arms 16 and 18 are provided at a longitudinal end of the pendulum weight 14 in a direction perpendicular to the longitudinal direction. The arms 16 and 18 are supported by sleeves 20 and 22 so as to rotate about a first rotation axis in the Y direction orthogonal to the laser light emission optical axis direction of the laser pointers 10 and 12. . The support base 28 of the sleeves 20 and 22 is provided on the base 30 so as to rotate on a second rotation axis in the X direction orthogonal to the first rotation axis.

Next, the operation of the present embodiment will be described with reference to FIG. For example, the magnet of the base 30 is attached to a side surface of a steel frame or the like. Then, due to the weight of the pendulum weight 14, the sleeves 20, 22 rotate in the direction of arrow FA, and the pendulum weight 14 rotates in the direction of arrow FB, and swings like a pendulum. This swinging is immediately settled by the friction of the bearing part. Considering the stationary state, the laser light emission direction of the laser pointers 10 and 12 is vertical according to the same principle as the downward swing. Even if the surface on which the base 30 is attached is tilted from the vertical, the tilt is absorbed by the rotating part, and the laser light emission direction is the vertical direction. As described above, according to the present embodiment, even in a narrow place or an unstable place, blackout in the vertical direction can be easily performed in a short time.

Next, another embodiment of the present invention will be described with reference to FIG. This embodiment is different from the above embodiment in that laser beams are output in the horizontal direction by providing laser pointers on the arms 16 and 18. In the figure, the above-described pendulum weight 14 is attached to the coupling block 50 so as to face downward in the figure. Arms 52 and 54 are attached to the connecting block 50 in the left-right direction in the figure.

In the present embodiment, the arms 52 and 54 also incorporate laser pointers 56 and 58. The optical axes LA, LB of these laser pointers 56, 58 coincide with each other and are in the ± Y direction. The optical axis and the optical axes LC and LD of the laser pointers 10 and 12 of the pendulum weight 14 are orthogonal to each other, and are in the ± X direction. The arms 52, 54 are rotatably supported at the ends of the sleeves 60, 62 via bearings (not shown). The sleeves 60 and 62 are symmetrically extended from the support base 64 in an L-shape, and the support base 64 is rotatably supported on the base 66 by a bearing (not shown). Thus, except that the laser pointers 56 and 58 are provided on the arms 52 and 54 that support the pendulum weight 14, the configuration is almost the same as that of the above-described embodiment.

The operation of this embodiment is the same as that of the above embodiment. Even when the base 66 is in contact with the inclined surface, the rotation of the sleeves 60 and 62 and the rotation of the pendulum weight 14 maintain the posture of the pendulum weight 14 so that the longitudinal direction is vertical. Therefore, laser beams are output from the laser pointers 10 and 12 in the vertical direction, and laser beams are output from the laser pointers 56 and 58 in the horizontal direction.

There are many embodiments of the present invention, and various modifications can be made based on the above disclosure. For example, various laser pointers have already been put into practical use, and any of them may be used. In the above embodiment, a plurality of pointers are used. However, a plurality of laser beams may be obtained by optically dividing laser light output from one laser oscillator.

Further, in the above-described embodiment, the base is configured by a magnet, but a magnet may be provided on a part of the base. Further, instead of the magnet, the operator may hold it by hand or attach it with a string, belt, screw, clip, or the like. The mounting surface does not need to be flat. Further, an optical element such as a mirror or a prism is provided on the laser light emitting side of any one of the laser pointers, thereby converting the optical axis of the laser light, and outputting the laser light not only horizontally and vertically but also in various directions. You may do so.

Further, in the above embodiment, the pendulum weight is rotatably supported by the bearing, but a magnet may be used instead of the bearing. FIG. 5 shows a main part of the embodiment using a magnet. FIG. 3A shows a cross section of a supporting portion of the arm 18, and a magnet 70 is provided at the tip of the arm 18. On the other hand, a magnet 74 that repels the magnet 70 is provided in the hole 72 of the sleeve 22 so as to face the same. The magnet 74 is fixed in the hole 72 by a cap 76. That is, the inside of the hole 72 and the outer periphery of the cap 76 are threaded, and the magnet 74 is pressed into the hole 72 by screwing the cap 76 into the hole 72. The same applies to the opposite arm 16 side. Since the magnets 70 and 74 are repelled in both the arms 16 and 18, the pendulum weight 14 is satisfactorily rotatably supported on the sleeves 20 and 22.

Next, FIG. 5B shows a cross section of a support portion of the support base 28, and the base 30 is provided with a projection 80 corresponding to the center of the rotation axis. At the tip of the projection 80, a magnet 82 is provided. On the other hand, magnets 84 and 86 that repel the magnet 82 are provided on the support base 28 so as to face each other with the magnet 82 interposed therebetween. Of these, the magnet 84 is fixed to the bottom of the concave portion 88 provided on the support 28, and the magnet 86 is fixed in the concave portion 88 by the cap 90. That is, the inside of the concave portion 88 and the outer peripheral side of the cap 90 are threaded, and the magnet 86 is pressed into the concave portion 88 by screwing the cap 90 into the concave portion 88. Since the magnet 82 on the side of the base 30 repels the magnets 84 and 86 on the side of the support 28, the support 28 is satisfactorily rotatably supported on the base 30.
