In other weights be the opposition side of lens barrel 15, trailing arm 5 and transverse arm 6, even if specially set counterweight can also seek
The weight balancing of the left and right centered on rack body 3.
Therefore, even if rack body 3 is not large-scale and solid device, it is also possible to stabilization state support lens barrel 15 and
20 liang of sides of monitor apparatus.Further, since the rack body 3 of the supporting grade of lens barrel 15 and monitor apparatus 20 can be relative to pedestal
2 are rotated freely centered on vertical axis V1, even if rotating rack body 3, the weight balancing of left and right is also constant, therefore lens barrel 15
Deng and monitor apparatus 20 stabilization bearing state it is constant.
Further, since trailing arm 5 and transverse arm 6 are the balances that balance is kept by the weight of counterweight W counteracting lens barrels 15
Formula structure, is not only left and right directions, and fore-and-aft direction can also seek the weight balancing centered on rack body 3, holder device 1
As more stable state.
In addition, monitor apparatus 20 when not in use, conveying when, arm 19 can be allowed to fold and become close to rack body 3
Receiving state.
In implementation state above by taking the monitor apparatus 20 for wearing special eye observation as an example, but this is not limited only to,
Can be the monitor apparatus of bore hole stereovision.
Technology according to the present invention aspect, trailing arm, transverse arm and mirror are provided with the one side of the left and right directions of rack body
Cylinder, and monitor apparatus are arranged at the top of the arm that opposite side in the lateral direction extends, thus can seek with rack body be
The weight balancing of the left and right at center, even large-scale monitor apparatus, it is also possible to evolved with less rack body and supported.By
Rotated freely centered on vertical axis relative to pedestal in rack body, even if so the weight for making rack body rotate left and right is put down
Weighing apparatus is also constant.
Further, since trailing arm and transverse arm are the balance type structure of the weight that lens barrel is offset by counterbalance, therefore can seek
Weight balancing before and after asking centered on rack body, holder device turns into more stable state.
Further, since arm is folded freely in the horizontal direction, therefore the position of monitor apparatus can be carried out by folding degree
Put, the adjustment in direction, and when not in use, conveying when arm is folded, make monitor apparatus become close to rack body storage
State.
And then, because the angle of lighting unit and the optical axis of objective lens optical system are inconsistent, therefore in visual area reflection just
Reflex components are difficult to be returned directly to objective lens optical system, can avoid the harmful effect to image unit.
