DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for illuminating black ink in civil engineering, construction, and other fields that can display horizontal and vertical lines.

[0002]

2. Description of the Related Art In recent years, a blackout device using a laser beam has been used for leveling and verticalizing a building and the state of building construction, and for checking the horizontal and vertical state of the building.

[0003] In this ink-marking device, a laser beam irradiating part is turned around an installation axis of a tripod stand or the like to irradiate horizontally to a predetermined position on a wall surface of a building, respectively, so as to black-out, or in a dirt or ceiling. There has been known an apparatus in which marking is performed by irradiating a laser beam onto a marking section such as a marking section to perform a blackout operation.

[0004] However, in these blackout means,
Although it is disclosed that the laser light is swirled horizontally, it is merely a manual swirl so that the laser light can be irradiated to a predetermined horizontal position, and the laser light can be displayed horizontally in a continuous line state. It took a lot of time to get the ink out.

[0005]

For this reason, there has been known an apparatus which can easily display a horizontal blackout line as a continuous line by rotating a laser light source unit, but cannot perform a vertical line. A means that can easily mark both the horizontal and vertical directions has been desired.

The rotation motor for the vertical line is set to 100 r. p. m or more, preferably 200 to 400 r.
p. m and at the same time or higher.

The main body 2 of the illuminating device 3 and the side surfaces of the illuminating device 3 of the illuminating devices 4 and 5 which are driven to rotate in this manner are made of a transparent material, or a slit or the like is opened at a predetermined position. Light beams such as laser beams emitted from the illuminators 4 and 5 can be displayed as horizontal or vertical marking lines in a continuous line on the wall surface of a building or the like.

In the illumination device 3 described above, the rigid mounting base 11 is supported by a shaft support member 23 and a motor shaft 16 as shown in FIGS. 1 and 2, and is mounted on the mounting base 11 as shown in FIG. A tilting lever 25 is lockably fitted in the required arcuate guide groove 24 provided, and the illuminating devices 4 and 5 are tilted to a required angle so that an oblique blackout line can be displayed. .

The bottom of the black-out lighting device 1 is
The leg 26 is erected to make it easier to install at a predetermined location. If necessary, instead of the above-mentioned gyro mechanism, the illuminating device 3 can be placed horizontally on a level (not shown) by making the legs 26 adjustable up and down.

mm accuracy.

In the above description, two rays are radiated radially around the rotation axis. However, it is also possible to radiate three, four, etc. rays radially. It can be appropriately adopted so that the light beam looks like a continuous line.

As the light beam, a laser beam is preferable since the spread of the light beam is small. However, a light beam such as a white light beam or a light emitting diode can be used, and these light beams can be irradiated via an optical fiber.
