また基体10の中央部は適当に開口16され、重量が軽減されるようにすると共に、把持し易くしている。
The two sides 11 and 11 of the base body 10 are defined such that the side surfaces 11a and 11a intersect at right angles with the corner portion 13 as a vertex.
Further, the central portion of the base 10 is appropriately opened 16 so as to reduce the weight and facilitate gripping.

前記基体10の各辺11、11の先端付近に前記レーザー光源20、20が設けられている。
レーザー光源20、20は、それぞれ辺11、11に平行で、且つ前記照準点15を含む平面上にレーザー光が照射されるように配置されている。
またレーザー光源20、20は、単純には、基体10に固定して、レーザー光が辺11、11に平行で且つ基体10が当てがわれる床や壁にも平行となるような方向に照射されるようにすることができる。しかし本実施形態では、各レーザー光源20、20は、軸17によって、基体10の表面10a及び裏面10bに垂直な面上、即ち基体10が当てがわれる床や壁に垂直な面上において、首振り乃至回転できるように構成されている。
The laser light sources 20 and 20 are provided near the tips of the sides 11 and 11 of the base 10.
The laser light sources 20 and 20 are arranged so as to be irradiated with laser light on planes parallel to the sides 11 and 11 and including the aiming point 15, respectively.
In addition, the laser light sources 20 and 20 are simply fixed to the base 10 and irradiated in a direction such that the laser light is parallel to the sides 11 and 11 and also to the floor or wall to which the base 10 is applied. Can be. However, in this embodiment, each laser light source 20, 20 swings on the surface perpendicular to the front surface 10 a and the back surface 10 b of the base 10, that is, on the surface perpendicular to the floor or wall to which the base 10 is applied, by the shaft 17. It is configured to rotate.

また基体10には、各レーザー光源20、20の電源となる電池を取り替え自在に収納した電源部18、18と、該電源部18、18による各レーザー光源20、20への電力供給をオン、オフさせるスイッチ部18a、18aが設けられている。   Further, the base 10 is provided with power supply units 18 and 18 in which batteries serving as power sources of the laser light sources 20 and 20 are slidably stored, and power supply to the laser light sources 20 and 20 by the power supply units 18 and 18 is turned on Switch portions 18a and 18a to be turned off are provided.

前記透視用穴部14、電源部18、スイッチ部18a、レーザー光源20等は、何れも基体10の表・裏面10a、10bから突出しないように構成することができるが、本実施形態では透視用穴部14、電源部18、スイッチ部18aは基体10の表面10aに多少突出した状態で構成されている。また基体10の裏面10bには、ごく小さな脚19が突出して設けられている。   The fluoroscopic hole portion 14, the power source portion 18, the switch portion 18a, the laser light source 20, and the like can be configured so as not to protrude from the front and back surfaces 10a and 10b of the base body 10, but in this embodiment, for fluoroscopic purposes. The hole 14, the power supply unit 18, and the switch unit 18 a are configured to protrude slightly from the surface 10 a of the base body 10. A very small leg 19 protrudes from the back surface 10 b of the base 10.

図2を参照して、本実施形態に係るレーザー式墨出し具1の使用例を説明する。この使用例は壁や柱等の測量基準面SFに対する直角方向に墨出しする使用例である。
即ち、壁Wや柱等の測量基準面SFに対して基体10の一辺11を当てがった状態で、他方の辺11側にあるレーザー光源20をスイッチオン状態とすることで、レーザー光Lが測量基準面SFに直角な方向に照射される。このとき、前記測量基準面SF上の所定の測量基準点SPに照準点15を合わせることで(図4参照)、該測量基準点SPにおける測量基準面SFに直角な方向にレーザー光Lが照射されことになる。
With reference to FIG. 2, the usage example of the laser-type marking device 1 which concerns on this embodiment is demonstrated. This usage example is a usage example in which marking is performed in a direction perpendicular to the surveying reference surface SF such as a wall or a column.
In other words, the laser light source 20 on the other side 11 side is switched on in a state in which one side 11 of the base 10 is applied to the surveying reference surface SF such as the wall W or the column, so that the laser light L Is irradiated in a direction perpendicular to the surveying reference plane SF. At this time, by aligning the aiming point 15 with a predetermined surveying reference point SP on the surveying reference surface SF (see FIG. 4), the laser beam L is irradiated in a direction perpendicular to the surveying reference surface SF at the surveying reference point SP. Will be.

図3を参照して、前記レーザー式墨出し具1を、床F面付近に配置できる場合は、レーザー光源20のレーザー光Lの方向を床Fにほぼ平行に照射することで、床F面に沿った墨出しを行うことができる。
また前記レーザー式墨出し具1を、床F面より上方の位置の壁Wに配置する必要がある場合には、レーザー光源20を軸17の周りで傾けることにより、レーザー光Lを傾斜方向に照射して、床F面に所定のポイントPを照射点として墨出しすることができる。
Referring to FIG. 3, when the laser marking device 1 can be arranged near the floor F surface, the direction of the laser light L of the laser light source 20 is irradiated almost parallel to the floor F, so that the floor F surface You can make inking along.
In addition, when it is necessary to dispose the laser marking tool 1 on the wall W at a position above the floor F surface, the laser light source 20 is tilted around the axis 17 so that the laser light L is tilted. Irradiation can be performed on the floor F surface with a predetermined point P as an irradiation point.

図4を参照して、本実施形態に係るレーザー式墨出し具1の他の使用例を説明する。この使用例は、床F等の測量基準面SF上にレーザー式墨出し具1の裏面10bを接地して当てがい、レーザー式墨出し具1の照準点15を前記測量基準面SFの測量基準点SPに一致するように位置決めして、測量基準点SPを中心とした直角方向の墨出しを行う例である。
即ち、レーザー式墨出し具1の基体10の裏面10bをその脚19で床F面である測量基準面SFに当てがい、この状態で基体10の照準点15を、測量基準面SFの測量基準点SPに対し、透視用穴部14を通して視認しながら相互に重ね合わせる。そして基体10の一方のレーザー光源20から照射されるレーザー光Lを測量基準面SF上等の所定の基墨Q(基準線、基準点を意味する)に一致させることで、この基墨Q方向に対して直角な方向を他方のレーザー光源20からのレーザー光Lによって墨出しすることができる。この場合、レーザー光源20、20の照射角度を調整することで、床F上に直角方向のポイントPを照射点として墨出しができる。
With reference to FIG. 4, another example of use of the laser-type marking device 1 according to this embodiment will be described. In this use example, the back surface 10b of the laser marking device 1 is grounded and applied to the surveying reference surface SF such as the floor F, and the aiming point 15 of the laser marking device 1 is set as the surveying standard of the surveying reference surface SF. This is an example in which positioning is performed so as to coincide with the point SP, and marking is performed in a perpendicular direction with the surveying reference point SP as the center.
That is, the back surface 10b of the base body 10 of the laser marking device 1 is applied to the surveying reference surface SF which is the floor F surface with the legs 19, and in this state, the aiming point 15 of the base body 10 is set to the surveying reference surface of the surveying reference surface SF. The points SP are overlapped with each other while being visually recognized through the fluoroscopic hole 14. The laser beam L emitted from one laser light source 20 of the base 10 is made to coincide with a predetermined ink Q (which means a reference line or a reference point) on the surveying reference surface SF, etc. The direction perpendicular to the direction can be marked by the laser light L from the other laser light source 20. In this case, by adjusting the irradiation angle of the laser light sources 20 and 20, the ink can be drawn on the floor F with the point P in the perpendicular direction as the irradiation point.

上記において、墨出し動作する各平面M1、M2は、基体10の照準点15及びそれに位置合わせした測量基準点SP上で直交し、基体10の互いに直角な2辺11、11に平行で、且つ基体10の表・裏面10a、10bに直交する向きとなる。この結果、例えば基体10をその床Fに置いて測量基準点SPに照準点15を位置合わせした図4の状態では、測量基準点SPにて直交する2つの鉛直な平面M1、M2上での墨出し動作が正確にできる。
勿論、上記のような床F上での墨出し動作は、壁Wなどの垂直面でも行える。
In the above, each of the planes M1 and M2 on which the marking operation is performed is perpendicular to the aiming point 15 of the base 10 and the surveying reference point SP aligned therewith, parallel to the two sides 11 and 11 perpendicular to each other, and The orientation is perpendicular to the front and back surfaces 10a and 10b of the substrate 10. As a result, for example, in the state shown in FIG. 4 in which the base 10 is placed on the floor F and the aiming point 15 is aligned with the surveying reference point SP, the measurement is performed on two vertical planes M1 and M2 orthogonal to the surveying reference point SP. Accumulation operation can be performed accurately.
Of course, the marking operation on the floor F as described above can also be performed on a vertical surface such as the wall W.

本実施形態によれば、レーザー式墨出し具1が簡単な構成で、且つ扁平で小型であり、従って使い易く、また携帯し易くて安価なものとなる。
またレーザー式墨出し具1をその基体10で種々の測量基準面SPに当てがい、或いは更に測量基準点SPに対して照準点15を位置合わせすることも簡単に精度よくでき、直角測量はもとより、2つのレーザー光源20、20の首振り、又は回転角度を簡単に調整することで、測量基準点SPにて直交する2つの平面上M1、M2での墨出し動作による墨出しが正確にできる。
また基体10の一対の辺11、11の側面11a、11aの頂角の角度を90以外の角度に設定することで、直角以外の墨出し作業もできる。
また基体10やレーザー光源20の外筒はアルミニウム製とすることによって、軽量で更に取り扱い易くて錆び難く、寿命の長いものとなる。
また基体10自体を透明なものとすれば、照準点15を測量基準点SPに位置合わせするための特別な透視用穴部14は不要となる。
またレーザー光源20、20の首振りや回転の角度を記す目盛りを設けておくと便利である。
According to the present embodiment, the laser marking device 1 has a simple configuration, is flat and small, and is therefore easy to use, easy to carry, and inexpensive.
Further, the laser marking tool 1 can be applied to various surveying reference planes SP with the base 10 or the positioning of the aiming point 15 with respect to the surveying reference point SP can be easily performed with high accuracy. By simply adjusting the swivel or rotation angle of the two laser light sources 20, 20, the inking by the inking operation on the two planes M1 and M2 orthogonal to the surveying reference point SP can be accurately performed. .
Further, by setting the apex angle of the side surfaces 11a, 11a of the pair of sides 11, 11 of the base body 10 to an angle other than 90, it is possible to perform a marking operation other than a right angle.
Further, the outer cylinder of the substrate 10 and the laser light source 20 is made of aluminum, so that it is lightweight, easy to handle, hardly rusted, and has a long life.
If the base body 10 itself is transparent, a special fluoroscopic hole 14 for aligning the aiming point 15 with the surveying reference point SP is not necessary.
In addition, it is convenient to provide a scale for indicating the angle of swinging and rotation of the laser light sources 20 and 20.

勿論、既述したように、レーザー式墨出し具1は、その2辺11、11が規定する角度を90度に固定する他、これに限られることはなく、基体10の2辺11、11がなす角度を直角以外の角度に切り換え、又は変更できる手段として、ヒンジ構造を有したものとすることもできる。これによって2つのレーザー光源20、20が墨出し動作する2つの平面が測量基準点SPでなす交差角度を90度以外に設定でき、測量環境への対応幅が拡大する。この場合、2辺11、11間が規定する角度を読み取る目盛りや目盛機構を備えるようにすることで、角度調整が便利になる。   Of course, as described above, the laser-type marking tool 1 is not limited to the angle defined by the two sides 11 and 11 and is not limited to this, and the two sides 11 and 11 of the substrate 10 are not limited thereto. As a means for switching or changing the angle formed by the angle to an angle other than a right angle, a hinge structure may be used. As a result, the crossing angle formed by the surveying reference point SP between the two planes on which the two laser light sources 20 and 20 perform the marking operation can be set to other than 90 degrees, and the corresponding range to the surveying environment is expanded. In this case, the angle adjustment is convenient by providing a scale or a scale mechanism for reading an angle defined between the two sides 11 and 11.
