従来、測距装置には図４に示すものがあった。図において、１は制御部、２は レーザ送信部、３はレーザ発射指令信号、４は送信光軸、５はレーザ発射信号、 ６は受信光軸、７は受信光学系、８は光検出器、９はレーザ受信信号、１０は受 信光学系に設けた送信部取り付け座、１９は取り付け角度調整機構である。 Conventionally, there is a distance measuring device shown in FIG. In the figure, 1 is a control unit, 2 is a laser transmission unit, 3 is a laser emission command signal, 4 is a transmission optical axis, 5 is a laser emission signal, 6 is a reception optical axis, 7 is a reception optical system, and 8 is a photodetector. Reference numeral 9 is a laser reception signal, 10 is a transmitter mounting seat provided in the reception optical system, and 19 is a mounting angle adjusting mechanism.
【０００３】 次に、動作について説明する。制御部１からのレーザ発射指令信号３により、 送信部２が動作し、レーザ光を発射すると同時にレーザ発射信号５を制御部１へ 送る。送信光軸４の方向に発射されたレーザ光は、目標物で反射し、受信光軸６ の方向から戻ってくるレーザ光は受信光学系７で集光され、光検出器８で検出さ れる。レーザ光が検出されると、レーザ受信信号９が制御部に送られる。制御部 １では、レーザ発射信号５とレーザ受信信号９の時間間隔から、目標物までの距 離を求める。Next, the operation will be described. The transmitter 2 operates according to the laser emission command signal 3 from the controller 1 and emits a laser beam and at the same time sends a laser emission signal 5 to the controller 1. The laser light emitted in the direction of the transmission optical axis 4 is reflected by the target object, and the laser light returning from the direction of the reception optical axis 6 is condensed by the reception optical system 7 and detected by the photodetector 8. .. When the laser light is detected, the laser reception signal 9 is sent to the control unit. The control unit 1 obtains the distance to the target object from the time interval between the laser emission signal 5 and the laser reception signal 9.
【０００４】 測距装置において高い測距能力を得るには、目標からの反射光を効率的に受信 する必要がある。送信部２は、受信光学系７に設けた取り付け座１０に対し、角 度調整機構１９を介して取り付けられており、角度調整機構１９を調整すること により、送信光軸４の方向と受信光軸６の方向を一致することができる。In order to obtain a high distance measuring ability in the distance measuring device, it is necessary to efficiently receive the reflected light from the target. The transmitter 2 is attached to the mounting seat 10 provided in the receiving optical system 7 via the angle adjusting mechanism 19. By adjusting the angle adjusting mechanism 19, the direction of the transmitting optical axis 4 and the receiving optical axis 4 are adjusted. The directions of axis 6 can be matched.

従来の測距装置は以上のように構成されているので、送信光軸と受信光軸の方 向を一致させるために角度調整機構を設けているが、光軸を三次元的に同方向に するには、あおり機構と回転機構を組み合わせた直交する二方向の角度調整機構 を設ける等複雑な角度調整機構を設ける必要があった。調整機構が複雑であると 、コストが高くなる、調整が面倒である、調整状態の維持が困難であるなどの問 題があった。 Since the conventional distance measuring device is configured as described above, an angle adjusting mechanism is provided to match the directions of the transmitting optical axis and the receiving optical axis. To do so, it was necessary to provide a complicated angle adjustment mechanism such as an angle adjustment mechanism in two orthogonal directions that combines a tilt mechanism and a rotation mechanism. If the adjustment mechanism is complicated, there are problems such as high cost, troublesome adjustment, and difficulty in maintaining the adjustment state.
【０００６】 この考案は上記のような問題点を解消するためになされたもので、送信光軸と 受信光軸を一致させる機構が簡単であり、調整および調整状態の維持の容易な測 距装置を提供することを目的とする。The present invention has been made in order to solve the above-mentioned problems, and has a simple mechanism for aligning the transmission optical axis and the reception optical axis, and it is easy to perform adjustment and maintenance of the adjustment state. The purpose is to provide.

【００１３】 次に動作について説明する。測距装置としての動作は従来技術と同様である。 取り付け座１０と送信部２の結合方法としては、取り付け座１０側にねじ穴Ｈ1 を設け、送信部２側にばか穴Ｈ2 を設け、取り付け座面１０面内での送信部２の 取り付け角度を調整しながらねじＮでねじ止めする。取り付け角度を調整するこ とにより、送信光軸４は図１の紙面に垂直方向に動く。図２において、送信光軸 方向は、標準位置Ｔを挟んで軌跡１３に示すように直線状動く。Next, the operation will be described. The operation as the distance measuring device is similar to that of the conventional technique. As a method of connecting the mounting seat 10 and the transmitting unit 2, a screw hole H 1 is provided on the mounting seat 10 side and a fool hole H 2 is provided on the transmitting unit 2 side, and the transmitting unit 2 is mounted within the surface of the mounting seat surface 10. Screw with screw N while adjusting the angle. By adjusting the mounting angle, the transmission optical axis 4 moves in the direction perpendicular to the paper surface of FIG. In FIG. 2, the transmission optical axis direction linearly moves across the standard position T as shown by a locus 13.
【００１４】 図１において、光学楔１２は受信光軸６を中心に回転する光学楔保持機構１１ に取り付けられており、光学楔１２は受信光軸６を中心に回転する。光学楔１２ を回転させると、受信光軸は前方正面から一定の角度をなして回転する。図２に おいて、受信光軸方向は、標準位置Ｒを中心とし軌跡１４に示すように円状に動 く。In FIG. 1, the optical wedge 12 is attached to an optical wedge holding mechanism 11 that rotates about the reception optical axis 6, and the optical wedge 12 rotates about the reception optical axis 6. When the optical wedge 12 is rotated, the reception optical axis rotates at a constant angle from the front front. In FIG. 2, the receiving optical axis direction moves in a circle around the standard position R as shown by a locus 14.
【００１５】 図２において、送信光軸と受信光軸がそれぞれ軌跡１３と軌跡１４の交点Ｓの 方向になるよう調整することにより、図１の送信光軸４の方向と受信光軸６の方 向を一致させることができる。In FIG. 2, the transmission optical axis and the reception optical axis are adjusted so as to be in the directions of the intersections S of the trajectories 13 and 14, respectively, so that the directions of the transmission optical axis 4 and the reception optical axis 6 in FIG.

Reference numeral 16 is an O-ring, 17 is a holding ring, and 18 is a distance measuring device case.
【００１７】 次に動作について説明する。測距装置ケース１８の送信部２の前方に平行平板 １５がＯリング１６と押え環１７で取り付けられている。平行平板１５は送信部 から出るレーザ光を方向を変えずに透過する。また、平行平板１５と測距装置ケ ース１８の間にはＯリング１６があるので気密を維持できる。測距装置ケース１ ８の受信光学系７の前方に光学楔１２がＯリング１３と押え環１４で取り付けら れている。光学楔１２は楔角の大きさと楔の方向により受信光軸方向を変化させ る。また、光学楔１２と測距装置ケース１８の間にはＯリング１３があるので気 密を維持できる。光学楔１２は押え環１４を緩めることにより受信光軸を中心に 回転することができ、取り付け座１０に対する送信部２の取り付け角度の調整と 、光学楔１２の回転角度調整により、実施例１と同様に送信光軸方向と受信光軸 方向を一致させることができる。光学楔１２の楔角は、通常１分程度で十分であ るので、平行平板と同様の固定が可能であり、気密保持も可能である。Next, the operation will be described.

Similarly, the transmitting optical axis direction and the receiving optical axis direction can be matched. Since the wedge angle of the optical wedge 12 is usually about 1 minute, it can be fixed in the same manner as a parallel plate and can be kept airtight.
【００１８】 なお、上記実施例１では光学楔１２を受信光学系側に設けたが、送信部２側に 設けても良い。また、実施例２も同様に平行平板１５を受信光学系７に光学楔１ ２を送信部２側に設けても良い。Although the optical wedge 12 is provided on the receiving optical system side in the first embodiment, it may be provided on the transmitting unit 2 side. Similarly, in the second embodiment, the parallel plate 15 may be provided in the receiving optical system 7 and the optical wedge 12 may be provided in the transmitting unit 2 side.

異常のように、この考案によれば、受信光学系取り付け座１０に対する送信部 ２の取り付け角度調整と、光学楔１２の回転角度調整により光軸整合を行うので 、複雑な角度調整機構が不要となる。また、複雑な角度調整機構を使わないので 光軸整合および整合状態の維持が容易となる。 Like the anomaly, according to the present invention, since the optical axis alignment is performed by adjusting the mounting angle of the transmitting unit 2 with respect to the receiving optical system mounting seat 10 and adjusting the rotation angle of the optical wedge 12, a complicated angle adjusting mechanism is unnecessary. Become. Moreover, since a complicated angle adjusting mechanism is not used, it is easy to maintain the optical axis alignment and alignment.
