【産業上の利用分野】この考案は、少なくとも２本の杆
部材を連結して使用する測量杆に関するものである。[Industrial application] This invention has at least two rods.
The present invention relates to a surveying rod that is used by connecting members .
【０００２】[0002]

異なる複数の杆部材が順次多段に嵌合連結されてなり、

して使用している。2. Description of the Related Art A general structure of a conventional surveying rod is a structure in which a plurality of rod members having different diameters are sequentially fitted and connected in multiple stages,
The scales provided on the surface of each of the rod members are arranged to be continuous with each other when the surveying rod is extended. And
At the time of surveying, the rod member is fitted and connected, and the surveying rod is used in an extended state.
【０００３】ところで、電車の線路上や道路上、あるい
は下水道の中等、昼間測量を行うためには交通を遮断し

でも薄暗い場所で測量を行わなければならないことがし
ばしばあるが、上記のように構成された測量杆では、そ
のような場所での測量にあっては、杆部材の表面に施さ
れた目盛を読み取ることが困難となる。By the way, in order to carry out daytime surveys, such as on train tracks, on roads, in sewers, etc., traffic must be cut off. Although often necessary, it is difficult for the surveying rod configured as described above to read the scale provided on the surface of the rod member during surveying in such a place.
【０００４】そこで、従来このような場所で測量を行う
場合には、目盛の部分に懐中電灯等でライトを当てる
等、外部から目盛部分に光を当てた上で測量を行ってい
た。Therefore, conventionally, when surveying is performed in such a place, the scale is calibrated by illuminating the scale with light from the outside, for example, by illuminating the scale with a flashlight or the like.
【０００５】また近頃では、上述のような測量杆を用い
た測量方法に代わって、レーザー光線等を利用した光波
距離測定装置を用いた測量が行われることもある。Recently, instead of the above-mentioned surveying method using a surveying rod, surveying using a lightwave distance measuring device utilizing a laser beam or the like may be performed.

【０００７】すなわち、目盛の部分に外部から光を当て
て測量を行うものでは、高い位置となる測量杆の表面が
十分明るくできず、しかも明るさにムラができ、見難
い。That is, in the case where surveying is performed by shining light on the scale portion from the outside, the surface of the surveying rod at a high position cannot be sufficiently bright, and the brightness is uneven, which is difficult to see.
【０００８】一方、レーザー光線等を利用する光波距離
測定装置は、装置自身の構成が複雑であり、製造単価が
高い。したがって、これを比較的簡易な測量に使用する
ことは、測量にかかるコストの（従来の測量杆を用いる
方法に比べて）上昇を招くことになる。On the other hand, the light-wave distance measuring device using a laser beam or the like has a complicated structure and has a high manufacturing cost. Therefore, using this for a relatively simple survey leads to an increase in the cost of the survey (compared to the conventional method using the survey rod).
【０００９】本考案はかかる従来の問題点に鑑みてなさ

する。The present invention has been made in view of the above conventional problems, and in a surveying rod having a multi-stage structure,
It is an object of the present invention to provide a surveying rod that can be used even at night and the like and can be manufactured at low cost by raising the scale by illuminating the surveying rod from the inside.

杆部材自身が発光する。(1) The rod member that constitutes the surveying rod has a light-transmitting property, and since the rod member has the reflector and the light emitter over the entire internal length, by making the light emitter emit light,
The rod member itself emits light.

放出する。(2) The rod member constituting the surveying rod has a light-transmitting property and is connectable in a multi-step manner so that it can be extended and contracted freely. The rod member has a reflecting member, a light-emitting body and a light diffusing member, The reflecting member is attached to the entire length of the inside of the rod member so as to penetrate through the rod member in the axial direction, and the light emitters are arranged at intervals over the entire length of the reflecting member.
Since the light diffusing member has a light-transmitting property and is provided so as to be interposed between the inner surface of the rod member and the luminous body, when the luminous body emits light, the light emitted by the luminous body emits light. It is diffused by passing through the diffusion member and is emitted to the outside.

する。Therefore, when the surveying rod is viewed from the outside in a state where the luminous body emits light, the entire rod member appears to shine brightly. In other words, the scale attached to the surface of the rod member is entirely raised by the light emitted from the light emitting body.
Further, by interposing a light shielding member between the light emitter and the inner surface of the light diffusing member, the light emitted from the inside does not appear as dots on the rod member, and the whole looks uniformly bright and the scale is clearly read. You can Furthermore, by using white for the reflecting member, the light emitted by the light emitting body is reflected by the reflecting member and emitted to the outside, which makes the scale easy to read.
