Bearing concave grooves 5 facing each other on the upper surfaces of 31e and the partition and 31f.
6 and 57 are formed, and the rolling wheel shafts 46b and 46c of the operation rolling wheel 46 are fitted into these bearing concave grooves 56 and 57 so as to be dropped.
なお、操作転輪46の組み込みは左右の光学系機構を組み
付け後に行なう。The operation wheel 46 is incorporated after the left and right optical system mechanisms are assembled.
既に述べたように、操作転輪46には螺子杆47、移動体4
9、連動腕48a、48bが一体的に連結してあるので、これ
らの各部品が操作転輪46を上記のように組み込むことに
よって共に組み込まれる。As described above, the operation wheel 46 has the screw rod 47 and the moving body 4
9. Since the interlocking arms 48a and 48b are integrally connected, each of these parts is incorporated together by incorporating the operation roller 46 as described above.
この場合、連動腕48aは第４図から分かる通り、切欠孔3
1a1、33aの上方から入って対物レンズ鏡筒32の凹溝32a
内に達する。In this case, as shown in FIG. 4, the interlocking arm 48a has the cutout 3
1a 1 and 33a enter from above and the concave groove 32a of the objective lens barrel 32
Reach in.
右側の連動腕48bについても同様である。The same applies to the right interlocking arm 48b.
上記の如く嵌合させた転輪軸46b、46cは第１の内室54と
第２の内室55とを被蓋する蓋体58を被着することにより

着剤による固着によって被着させてもよい。The lid 58 is provided with a window hole 58a for partially protruding the operation wheel 46, and is attached using a locking mechanism provided between the lid 58 and the binocular body 31. It may be applied by fixing with an adhesive.
上記構成の双眼鏡は、肉眼間隔に合わせるようにして接
眼レンズ鏡筒35を旋回操作すると、この鏡筒35が軸筒33
を回動軸とし、小球45を支点として旋回する。In the binoculars having the above-mentioned configuration, when the eyepiece lens barrel 35 is pivotally operated so as to be aligned with the naked eye distance, the barrel 35 causes the barrel 33 to move.
Is used as a rotation axis, and the small ball 45 is used as a fulcrum to turn.
右側の接眼レンズ鏡筒53についても同様に旋回操作すれ
ば、一例として第２図に仮線をもって示したように眼幅
調節することができる。If the eyepiece lens barrel 53 on the right side is similarly rotated, the interpupillary distance can be adjusted as shown by a phantom line in FIG. 2 as an example.
この眼幅調節の際には、軸筒33の切欠孔33aが逃げ孔、
対物レンズ鏡筒32の凹溝32aが逃げ溝となるため、連動
腕48aには何等影響しない。At the time of this interpupillary adjustment, the notch hole 33a of the shaft tube 33 is an escape hole,
Since the concave groove 32a of the objective lens barrel 32 serves as an escape groove, the interlocking arm 48a is not affected at all.
この点は右側の光学系機構50についても同様となる。This also applies to the optical system mechanism 50 on the right side.
フォーカシングに当っては、操作転輪46を回転操作す

操作転輪46の左回転または右回転にしたがい螺子杆47が
前後方向に移動し、これに伴って連動腕48a、48bも同方
向に移動する。According to the left rotation or right rotation of the operation wheel 46, the screw rod 47 moves in the front-rear direction, and accordingly, the interlocking arms 48a, 48b also move in the same direction.
なお、この動作時の螺子杆47の回動は移動体49が２つの
案内凸条部31c、31dに嵌合していることによって防止さ
れており、また、連動腕48aは切欠孔31a1及び33a内を移
動するため、軸筒33には影響しない。The rotation of the screw rod 47 during this operation is prevented by the moving body 49 being fitted into the two guide ridges 31c and 31d, and the interlocking arm 48a has the cutout hole 31a 1 and the interlocking arm 48a. It does not affect the barrel 33 because it moves inside the 33a.
対物レンズ鏡筒32は連動腕48aの移動によって駆動さ
れ、軸筒33内を摺動し、左側の光学系機構36の焦点を整
合させるように働く。The objective lens barrel 32 is driven by the movement of the interlocking arm 48a, slides in the barrel 33, and works to align the focus of the left optical system mechanism 36.
右側の光学系機構50は連動腕48bによって連動されて同
様に焦点が整合する。The optical system mechanism 50 on the right side is interlocked by the interlocking arm 48b, and the focus is similarly adjusted.

み込みに便利な生産し易い双眼鏡が提供できる。This simplifies the configuration of the interpupillary adjustment mechanism and the focus matching mechanism, and also reduces the number of parts. In particular, the focus matching parts are assembled in advance as first and second integrated parts. It is possible to provide binoculars which are easy to produce because they can be incorporated into the inner chamber of the vehicle, and these components are attached only by covering them.
