Description

本発明は、レーザー墨出し器の受光器に関するものである。  The present invention relates to a light receiver for a laser marking device.

レーザー墨出し器は、建物の内装工事や建築工事の現場で、レーザー可視光線を発射し、対象物体に水平ラインと垂直ラインを表示し、当該工事における水平・垂直出し作業を行なう装置である。従来、レーザー墨出し器を使用してレーザー光線を室内の壁などに当てて、建具などの取付箇所の位置決めをするときに、壁などに当たったレーザー光線が水平又は垂直の直線状に明るく光るのが容易に視認できる。レーザー墨出し器のレーザー可視光線は、通常、波長６３５ｎｍ前後の赤色半導体レーザー光線、又は、５３２ｎｍ前後の緑色半導体レーザー光線であって、これが壁などに反射することにより、その部分が赤色又は緑色に明るく光るので、容易に視認できるのである。しかし、屋外の直射日光下でレーザー墨出し器を使った場合、そのレーザー光線が構造物に当たっても、その色は太陽光のスペクトルの一部として吸収され、レーザー光線が反射して生じる水平ライン、垂直ラインの視認が困難であった。  The laser marking device is a device that emits laser visible light at the site of building interior construction or construction work, displays a horizontal line and a vertical line on a target object, and performs horizontal and vertical ejection work in the construction. Conventionally, when a laser marking device is used to place a laser beam on an indoor wall, etc., when positioning the attachment point such as joinery, the laser beam hitting the wall shines brightly in a horizontal or vertical straight line. Easy to see. The laser visible light of the laser marking device is usually a red semiconductor laser beam having a wavelength of about 635 nm or a green semiconductor laser beam having a wavelength of about 532 nm, and when this is reflected on a wall or the like, the portion shines brightly in red or green. Therefore, it is easily visible. However, when using a laser marking device under outdoor direct sunlight, even if the laser beam hits the structure, the color is absorbed as part of the sunlight spectrum, and the horizontal and vertical lines generated by the reflection of the laser beam. Was difficult to see.

また、市販のレーザー墨出し器では、屋外で使用する場合に、レーザー発光部の出力を大きくすることにより明るいレーザー光線を発射し、構造物に反射させたときの視認性を高めることができるが、人間の目に対する安全性の問題から制限があった。そこで、レーザー墨出し器のレーザー光線に対してのみ反応するセンサー（レーザー受光器）が、レーザー墨出し器と組み合わせて使用されている。市販のセンサーでは、レーザー光線を感知したときだけブザー音とランプの点滅により、センサーへの入光を知らせるのみで、レーザー光線の発射方向が、センサーの位置から外れている場合は、センサーで感知することができず、レーザー墨出し器及びレーザー受光器の位置決め自体が難しいという問題があった。  In addition, with a commercially available laser marking device, when used outdoors, it is possible to increase the visibility when emitting a bright laser beam by reflecting the structure by increasing the output of the laser emission part, There were limitations due to safety issues with the human eye. Therefore, a sensor (laser receiver) that reacts only to the laser beam of the laser marking device is used in combination with the laser marking device. With a commercially available sensor, only when a laser beam is detected, the buzzer sound and the flashing of the lamp only notify the light entering the sensor. If the direction of the laser beam is off the sensor position, the sensor should detect it. There is a problem that positioning of the laser marking device and the laser receiver itself is difficult.

本発明は、上述のような問題点に鑑みてなされたもので、レーザー墨出し器の受光器として、レーザー墨出し器から発射されたレーザー光線を、明るい場所でも視認できるようにしたレーザー受光器を提供することを目的とする。  The present invention has been made in view of the above-described problems, and a laser receiver capable of visually recognizing a laser beam emitted from a laser inking device as a light receiving device in a laser inking device.

本発明の実施の形態を、代表的な実施例に基づいて図を用いて説明する。図１は、本発明のレーザー受光器１０の構造を示す斜視図である。図１において、筐体１１はステンレスなどの金属製の立方形のケースであり、一面が入光口として開口し、その左右部に扉１３ａ，１３ｂがヒンジ１５ａ，１５ｂ，１５ｃ，１５ｄによって開閉自在に取り付けられ、また、上部には庇１４がヒンジ１５ｅによって開閉自在に取り付けられている。入光口の対面側には受光面１２が位置し、入光口から入射したレーザー光線の水平ライン・垂直ラインを映し出すようにしてある。
受光面１２は、入光口に対して凹の円弧状の曲面をなすように形成され、レーザー墨出し器から発射されるレーザー光線の色（波長）とほぼ同色に着色してある。また、筐体１１の、受光面１２を除く内面側は、つや消しの黒色に着色してある。Embodiments of the present invention will be described with reference to the drawings based on typical examples. FIG. 1 is a perspective view showing the structure of a laser receiver 10 of the present invention. In FIG. 1, a casing 11 is a cubic case made of a metal such as stainless steel, and one side opens as a light entrance, and doors 13a and 13b can be opened and closed by hinges 15a, 15b, 15c and 15d on the left and right sides thereof. In addition, a flange 14 is attached to the upper part by a hinge 15e so as to be freely opened and closed. The light receiving surface 12 is located on the opposite side of the light entrance, and the horizontal and vertical lines of the laser beam incident from the light entrance are projected.
The light receiving surface 12 is formed so as to form a concave arcuate curved surface with respect to the light entrance, and is colored in substantially the same color as the color (wavelength) of the laser beam emitted from the laser marking device. Moreover, the inner surface side except the light-receiving surface 12 of the housing | casing 11 is colored matte black.

図２（Ａ）は、本発明のレーザー受光器の使用状態を示す説明図であって、レーザー受光器１０は、扉１３ａ，１３ｂと庇１４を開いた筐体１１の右側面方向から見た状態を示している。レーザー受光器１０を使用するときは、レーザー墨出し器２０から発射されたレーザー光線３０がレーザー受光器１０の受光面１２に映るように、それぞれの設置位置を調整する。
図２（Ｂ）は、扉１３ａ，１３ｂと庇１４を開いた筐体１１の入光口方向から見た状態を示し、本図では、筐体１１の入光口の対面側に、レーザー光線の波長色と同色に塗装着色した平板状の受光面１２を取り付けた例を示している。図２（Ｂ）において、水平ライン３３は入射したレーザー光線３０が受光面１２上に反射した水平の軌跡であり、垂直ライン３４は入射したレーザー光線３０が受光面１２上に反射した垂直の軌跡である。水平ライン３３又は垂直ライン３４は、受光面１２にレーザー光線３０が当たった部分が線状に明るく光って、明確に視認できるものである。レーザー光線３０が受光面１２に当たったとき、受光面１２は、そのレーザー光線の波長色とほぼ同色に着色されているので、レーザー光線が当たった部分だけが線状に反射して明るく輝くのである。FIG. 2 (A) is an explanatory view showing the use state of the laser receiver of the present invention, and the laser receiver 10 is viewed from the right side surface direction of the housing 11 with the doors 13a and 13b and the collar 14 opened. Indicates the state. When the laser receiver 10 is used, the respective installation positions are adjusted so that the laser beam 30 emitted from the laser marking device 20 is reflected on the light receiving surface 12 of the laser receiver 10.
FIG. 2 (B) shows a state seen from the light entrance direction of the housing 11 with the doors 13a, 13b and the collar 14 opened. In this figure, the laser beam is seen on the opposite side of the light entrance of the housing 11. The example which attached the flat light-receiving surface 12 painted and colored by the same color as a wavelength color is shown. In FIG. 2B, the horizontal line 33 is a horizontal locus where the incident laser beam 30 is reflected on the light receiving surface 12, and the vertical line 34 is a vertical locus where the incident laser beam 30 is reflected on the light receiving surface 12. . The horizontal line 33 or the vertical line 34 is a portion where the laser beam 30 hits the light receiving surface 12 shines brightly in a linear shape and can be clearly recognized. When the laser beam 30 strikes the light-receiving surface 12, the light-receiving surface 12 is colored in substantially the same color as the wavelength of the laser beam, so that only the portion irradiated with the laser beam is reflected linearly and shines brightly.

図３（Ａ）は、平板状の受光面１２にレーザー光線３０が当たって反射する様子を示す説明図である。受光面１２のほぼ正面から入射したレーザー光線は、入射角＝反射角となるので、あまり拡散せず入射してきた方向に反射する。したがって、受光面１２の正面方向での視認性がよい。
図３（Ｂ）は、凸の円弧状の曲面に形成された受光面１２にレーザー光線３０が当たって反射する様子を示す説明図である。受光面１２のほぼ正面から入射したレーザー光線は、入射角＝反射角となって、拡散して反射する。したがって、受光面１２の正面から比較的広い範囲まで視認性がよくなる。
図３（Ｃ）は、凹の円弧状の曲面に形成された受光面１２にレーザー光線３０が当たって反射する様子を示す説明図である。受光面１２のほぼ正面から入射したレーザー光線は、入射角＝反射角となって、入射してきた方向に集中して反射する。したがって、受光面１２の正面の比較的狭い範囲で視認性がよくなる。但し、レーザー光線の反射光の拡散や集中の程度は、上記の凸又は凹の円弧状の曲面の曲率によって異なり、受光面１２の形状は、レーザー受光器の使用場所や目的に応じて最適のものを選択することが好ましい。
なお、図３（Ａ）〜（Ｃ）の各図は、レーザー光線３０が受光面１２の形状によって反射する様子を概念的に説明したものであって、本実施例の実際の寸法を正確に縮尺して描いたものではない。FIG. 3A is an explanatory view showing a state in which the laser beam 30 strikes the flat light-receiving surface 12 and is reflected. The laser beam incident from almost the front surface of the light receiving surface 12 has an incident angle = a reflection angle, and therefore reflects in the incident direction without being diffused so much. Therefore, the visibility in the front direction of the light receiving surface 12 is good.
FIG. 3B is an explanatory diagram showing a state in which the laser beam 30 strikes the light receiving surface 12 formed in a convex arcuate curved surface and is reflected. The laser beam incident from almost the front surface of the light receiving surface 12 is diffused and reflected with an incident angle = reflection angle. Therefore, the visibility is improved from the front surface of the light receiving surface 12 to a relatively wide range.
FIG. 3C is an explanatory view showing a state in which the laser beam 30 strikes the light receiving surface 12 formed in a concave arcuate curved surface and is reflected. The laser beam incident from almost the front surface of the light receiving surface 12 has an incident angle = reflection angle, and is concentrated and reflected in the incident direction. Therefore, the visibility is improved in a relatively narrow range in front of the light receiving surface 12. However, the degree of diffusion and concentration of the reflected light of the laser beam varies depending on the curvature of the convex or concave arcuate curved surface, and the shape of the light receiving surface 12 is optimal depending on the place and purpose of use of the laser receiver. Is preferably selected.
3A to 3C conceptually illustrate how the laser beam 30 is reflected by the shape of the light receiving surface 12, and the actual dimensions of the present embodiment are accurately scaled. It was not drawn.

図４は、平板状の受光面１２に、水平目盛１６及び垂直目盛１７を設けたことを示す説明図である。各目盛は最小目盛が１ｍｍで、１ｃｍ毎に大目盛と数値を記入してある。数値は中央を０とし、上下又は左右に１ｃｍ毎に記入している。通常、レーザー光線の反射軌跡である水平ライン又は垂直ラインの線幅が約１ｍｍ程度あるので、最小目盛は１ｍｍ又は２ｍｍとするのが適当である。本図では、平板状の受光面に目盛を設けた例を示したが、受光面１２が凸又は凹の円弧状の曲面を形成するタイプのものであっても、同様に目盛を設けることができる。  FIG. 4 is an explanatory diagram showing that a horizontal scale 16 and a vertical scale 17 are provided on the flat light-receiving surface 12. Each scale has a minimum scale of 1 mm, and a large scale and a numerical value are written every 1 cm. The numerical value is 0 at the center and entered every 1 cm vertically or horizontally. Usually, since the line width of the horizontal line or vertical line, which is the reflection locus of the laser beam, is about 1 mm, the minimum graduation is suitably 1 mm or 2 mm. In this figure, an example in which a scale is provided on a flat light receiving surface is shown, but even if the light receiving surface 12 is of a type that forms a convex or concave arcuate curved surface, a scale may be provided similarly. it can.

本実施例では、レーザー受光器１０の筐体１１は、薄いステンレス鋼板製で、高さ約２０ｃｍ、幅約６ｃｍ、奥行き約５ｃｍ、重さ約２５０ｇである。受光面１２は、平板状のものにあっては筐体の内面側をそのまま、レーザー墨出し器の発射するレーザー光線の波長色と同色に塗装しても良い。受光面１２が凸又は凹の円弧状の曲面を形成するタイプのものは、平板を曲面加工して塗装した上で筐体１１の内面に取り付けてもよい。受光面１２の塗装後の表面は、できる限り滑らかな面であることが望ましい。筐体は、工事現場で使用するので、軽量小型で丈夫であることが望ましい。図示しないが、三脚やパイプ、板体などに保持できるような取付具を備えることが望ましい。また、レーザー受光器自体の水平設置のために水準器を備えてもよい。  In this embodiment, the housing 11 of the laser receiver 10 is made of a thin stainless steel plate, and has a height of about 20 cm, a width of about 6 cm, a depth of about 5 cm, and a weight of about 250 g. If the light receiving surface 12 is a flat plate, the inner surface side of the housing may be coated as it is with the wavelength of the laser beam emitted by the laser marking device. A type in which the light receiving surface 12 forms a convex or concave arcuate curved surface may be attached to the inner surface of the housing 11 after a flat plate is curved and coated. The coated surface of the light receiving surface 12 is desirably as smooth as possible. Since the casing is used at a construction site, it is desirable that the casing is lightweight, small and strong. Although not shown, it is desirable to provide a fixture that can be held on a tripod, pipe, plate or the like. Moreover, you may provide a level for horizontal installation of laser receiver itself.
