Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tripod seat provided in a telescope for fixing and observing the telescope. Specifically, it relates to the position of the tripod seat.
[0002]
[Prior art]
A conventional telescope equipped with a tripod seat is configured as shown in FIGS. The prior art will be described below with reference to the drawings.
FIG. 3 is a longitudinal sectional view of a conventional monocular telescope, and FIG. 4 is a diagram in which a part of a tripod is shown in a state where the conventional monocular telescope is held on a tripod.
[0003]
In FIG. 3, the monocular telescope 10 has an objective lens unit 2 disposed on the object side. The eyepiece unit 3 is disposed on the image side through the focus lens group and the relay lens system. A focus ring 6 that drives and focuses the focus lens group is fitted on the outer periphery of the substantially central portion of the monocular telescope 10 so that the movement in the direction of the optical axis is restricted and is rotatable. A tripod seat 7 is provided below the telescope main body 10 a of the monocular telescope 10 between the focus ring 6 and the eyepiece unit 3.
[0004]
The balance position (center of gravity) of the monocular telescope 10 configured in this way is the black circle mark position shown in the figure.
FIG. 4 shows a state in which the monocular telescope 10 described in FIG. 3 is fixed to the tripod 8. As shown in FIG. 4, the focus ring 6 and the balance position (center of gravity) are located farther toward the objective lens unit 2 than the support position of the tripod 8. Further, as is well known, the tripod 8 can select the observation direction of the monocular telescope 10 by loosening the pan head operation handle 8a, and can be fixed at a desired position by narrowing.
[0005]
[Problems to be solved by the invention]
In such a conventional configuration, the balance position (center of gravity) of the monocular telescope 10 and the focus ring 6 are located closer to the objective lens side than the tripod seat 7, which is inconvenient in terms of operability and holding stability. was there.
First, since the balance position (center of gravity) is on the objective lens unit 2 side, if the pan head operating handle 8a is carelessly loosened while being fixed to the tripod 8, it suddenly falls to the opposite side of the operator, that is, the front side. Therefore, it is difficult to hold the monocular telescope 10 suddenly, and there is a problem that some trouble occurs in the monocular telescope 10.
[0006]
In addition, since the focus ring 6 is located on the opposite side of the operator of the tripod 8, when performing the focusing operation, the hand must be turned to the other side of the tripod. there were.
Furthermore, since the tripod base 7 is provided on the eyepiece lens unit 3 side, the pan head operating handle 8a of the tripod 8 is positioned closer to the operator side than the eyepiece lens unit 3, so that the operator can view the eyepiece lens unit 3. When looking into the camera, there was a problem that the upper body had to bend forward and it had to be observed in an unreasonable posture.
[0007]
The present invention has been made in view of such conventional problems, and the object of the present invention is to provide a tripod seat that has good operability and can quickly cope with inadvertent operations. To provide a telescope.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides the following.
[0009]
According to a first aspect of the present invention, an objective lens, an eyepiece lens, a focus lens group installed between optical paths connecting the objective lens and the eyepiece lens, the objective lens, the eyepiece lens, and the focus lens group are provided. In the monocular equipped with the monocular main body to be accommodated, the movement in the optical axis direction that drives and focuses the focus lens group in the optical axis direction on the outer periphery of the monocular main body at the center of gravity of the monocular is restricted. A focus ring provided so as to be rotatable in a closed state, a tripod seat is provided at a lower portion of the outer peripheral portion of the monocular main body, and the installation position of the tripod seat with respect to the monocular main body is a position adjacent to the focus ring. In addition, the position of the mounting part on the tripod seat tripod in the optical axis direction is a position that does not cover the objective lens provided at the tip of the monocular glasses in the optical axis direction. Location provides monocle with a tripod mount, wherein said is substantially the same position as the installation position of the tripod for monocular body.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a monocular telescope showing an embodiment of the present invention, and FIG. 2 is a diagram omitting a part of a tripod showing a state where the monocular telescope of an embodiment of the present invention is held on a tripod. is there.
In FIG. 1, a monocular telescope 1 has an objective lens unit 2 disposed on the object side. The eyepiece unit 3 is disposed on the image side through the focus lens group and the relay lens system. A focus ring 4 that drives and focuses the focus lens group is fitted to the outer periphery of the substantially central portion of the monocular telescope 1 so that the movement in the optical axis direction is restricted and the focus ring 4 is rotatable. A tripod seat 5 is provided below the telescope main body 1 a of the monocular telescope 1 between the focus ring 4 and the eyepiece unit 3. The tripod mount 5 is arranged so as to be positioned at least on the object side, that is, on the objective lens side with respect to the focus ring 4. The balance position (center of gravity) of the monocular telescope 1 at this time is positioned closer to the image side, that is, the eyepiece side of the tripod seat 5.
[0011]
In this embodiment, the balance position (center of gravity) of the monocular telescope 1 configured in this way is the black circle mark position shown in the figure.
FIG. 2 shows a state where the monocular telescope 1 described in FIG. 1 is fixed to a tripod 8. As shown in FIG. 2, the focus ring 4 and the balance position (center of gravity) are located closer to the eyepiece unit 3 than the support position of the tripod 8. Further, as is well known, the tripod 8 can select the observation direction of the monocular telescope 1 by loosening the pan head operation handle 8a, and can be fixed at a desired position by narrowing down.
[0012]
With the above configuration, in the embodiment of the present invention, the balance position (center of gravity) and the focus ring of the monocular telescope are located closer to the eyepiece than the tripod mount, so that the operability and the stability of holding are very good. It has become.
First, since the balance position (center of gravity) is on the eyepiece unit side, even if the pan head handle 8a is carelessly loosened while being fixed to a tripod, it falls to the operator side, that is, the rear side, so that it falls to the opposite side. This makes it easier to hold the monocular telescope from accidents.
[0013]
Further, since the focus ring 4 is located on the front side of the operator of the tripod 8, when performing the focusing operation, since the obstacle due to the tripod is eliminated as in the prior art, the operation becomes very easy.
Furthermore, since the tripod mount is provided on the objective lens unit side, the tripod head operating handle is located away from the eyepiece unit with respect to the operator, so that the operator can When looking into the camera, you can observe in a natural posture.
[0014]
In this embodiment, the monocular telescope has been described. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to all telescopes provided with a tripod seat.
[0015]
【The invention's effect】
As described above, according to the present invention, since the tripod mount is arranged closer to the objective lens than the center of gravity of the telescope in the telescope provided with a tripod seat, the operability is good and the operation is not performed carelessly. Also has the effect of enabling quick response.
