っているのが常であった。Conventional technology Conventionally, in order to know the vertical point in the fields of architecture and civil engineering, Part 9
1! A plumb bob like ii is used. However, plumber swings sway due to the influence of the wind, and new plumbers have a strong twisting force on the thread that makes them difficult to stop, so great efforts have been made to find the vertical point. Also, it is extremely rare that there is no wind at a construction site.
Most of the time, the hammer did not stop, and the verticality was often quite off.
そのため最新の高層ビルといえども上層では５０センチ
も１メートルも鉛直度がずれ、そのずれを内装で苦労し
て補うといった場合がほとんどである。As a result, even in the latest high-rise buildings, the verticality of the upper floors can vary by as much as 50 centimeters or even 1 meter, and in most cases, this discrepancy must be compensated for by the interior design.
上記の様な課題を解決するために第８図に示す様に鉛直

により上端から鉛直のレーザ光が出射されることを同層
したものである。In order to solve the above problems, a vertical pointing device as shown in FIG. 8 was developed. Hereinafter, the explanation will be given with reference to FIG. 1iii, 25 is a helium/neon gas laser, and the laser beam is always adjusted to the center of the earth by a gimbal 26. Also, 27 is a focusing lens for the laser beam. vK of the vertical indicator in the same figure The principle is that by setting the lower end of the straight laser beam emitted from both ends of a helium-neon gas laser at a certain reference point on the trajectory, a vertical laser beam is emitted from the upper end.

といった課題もあった。With this method, a vertical line can be obtained without being affected by the wind or the return of the thread. However, the above configuration has various problems as follows. First of all, in order to move the main body so that the laser beam from the bottom end matches the point underground,
Helium gas lasers inevitably oscillate. In addition, it is necessary to wait for the main body to come to a standstill and then move the main body again to correct the misalignment, and if you move one main body, it is necessary to repeat the process of waiting for the main body to come to a standstill again, which requires considerable effort. In addition, in order to focus the laser beam from the top, it is necessary to move the focusing lens up and down, but if the lens is even slightly tilted due to processing precision, the optical axis will shift significantly just by changing the focus. was there. Furthermore, since the method moves the point on the floor upward, when building an indoor building with several stories, it is necessary to set a vertical indicator on the frame on the intermediate floors, but in this case a helium/neon laser is used. However, with a conventional device, it is inevitably large and heavy, and it cannot be placed on a thin frame.Also, due to the weight, a large load is placed on the support pin in a gimbal structure, which increases the hysteresis caused by friction, making it difficult to improve accuracy. There were also issues such as:
そこで本発明は、上記の課題を一挙に解決すべく、屯に
、基ａポイントを床上に置くだけで精度よく。Therefore, in order to solve the above-mentioned problems all at once, the present invention can be used with high accuracy simply by placing the base point a on the floor.

Another object of the present invention is to provide a vertical/horizontal indicator that is equipped with a mirror that directly reflects the laser beam and has the function of indicating the watercolor line.

Since it is built into the main laser head, only two power supply lines are required.The power supply line is supplied from close to the gimbal fixing pin, and is a flexible thin wire, so the movement of the laser head is controlled. It is possible to obtain a highly accurate vertical line with a small influence on the vertical line. In addition, since a fixed lens is used, the optical axis does not shift due to lens movement, and the semiconductor laser focuses the light with a single convex lens, and is equipped with an output nozzle with a diameter of 1 mm to 2 mm. As a result, even at a distance of 10 meters, there is a 1 mm to 3
5mm to 10m as a strong core of light with a diameter of mm appears.
The weak light of mfii & degree is convenient for finding the position of the marker, the 1mm to 3mm lead can be used to find marks with high precision, and a simple configuration can provide a great effect.
With the above configuration, the main body can be moved in a small amount, so in the case of the first invention, if the levelness of the floor is not too out of order, simply setting the line on the case to the reference point on the floor will allow the main body to move on the floor with high accuracy. The reference point can be moved vertically upward using laser light. Further, the vertical indicator of the present invention according to the invention of FF12 can be made small and lightweight and can be attached to a thick steel pole, and the vertical laser beam from the vertical indicator can be attached to the steel pole so as to avoid misalignment with the mark that should originally receive it. By changing the inclination of the steel column, it is easy to make the steel column vertical. Further, according to the third invention, a horizontal line can be easily obtained by simply attaching a reflecting mirror to the laser head.

ＩＥシてもよい。The light receiving plate 17 of Embodiment (1) is made of a transparent or opaque material, and a scale is carved on a line 19 perpendicular to the magnet 20 and a line 21 parallel to the magnet 20. Note that the distance to the intersection (d) of 19 and 21 and the positional relationship and distance from (c) to (b) of the main body 1 are set to be equal. The light receiving plate is equipped with a magnet like the main body, so when setting it on the iron pole, the main body 1 and the light receiving plate 1
