As is well known, binoculars are used, for example, for watching sports and observing birds. In such a case, the spectator and the observer often encounter a scene that they want to record as a photograph, but it is easily conceivable to miss the shutter chance while switching the binoculars to the camera. Therefore, it has already been proposed to mount a camera on the optical observation device so that the optical observation device can immediately perform shooting without missing a shutter chance during watching or observing.

Conventionally, there has been disclosed binoculars with a photographing function of a type in which a camera section is simply mounted on the upper part of the binoculars (for example, see Patent Document 1). Naturally, such a pair of binoculars with a photographing function is provided with a pair of observation optical systems for magnifying and observing an observation object, and a photographing optical system for photographing the observation object. Since such a binocular with a photographing function is simply configured by adding a camera to the binocular, the entire configuration becomes bulky.

On the other hand, in order to give the binoculars with a photographing function a sufficient function as a binocular and a sufficient function as a camera, not only the focusing mechanism of the pair of observation optical systems but also the focusing mechanism of the photographing optical system. However, although the above-mentioned publication mentions such necessity, it does not disclose any specific configuration thereof. Further, in general, binoculars require adjustment of the distance between the optical axes of a pair of observation optical systems, so-called pupil distance adjustment, but the above publication discloses nothing about such pupil distance adjusting mechanism. Not not.

In short, in order to give the binoculars with a photographing function a sufficient function as a binocular and a sufficient function as a camera, the entire mechanism can have a complicated structure. In order to manufacture the binoculars with a photographing function having such a complicated mechanism as compactly as possible and at low cost, sufficient consideration must be given so that the assembling can be simplified as much as possible.

When the lower frame structure 10 and the upper frame structure 12 are assembled as shown in FIG. 2, the central main body portion of the upper frame structure 12, that is, the photographing section 12C, is the support plate structure 16 of the lower frame structure 10. It is fixed to the rectangular plate 16A. For such fixing, as shown in FIG. 3, a pair of holes 79a and 79b are formed along the front side edge of the rectangular plate 16A, and a pair of holes 79a and 79b are formed along the rear side edge of the rectangular plate 16A. Holes 80a and 80b are formed. On the other hand, as best shown in FIG. 8, a pair of columnar elements 81a and 81b are provided in a pair of holes 79a and 79b from the front bottom of the imaging unit 12C of the upper frame structure 12.
And a pair of columnar elements 82a and 82b from the rear bottom of the imaging unit 12C of the upper frame structure 12 and a pair of holes 80a and 80b.
It is projected as a fixed part at the same interval as. A screw hole 83 is formed in each columnar element, that is, the fixing portion (81a, 81b; 82a, 82b) from the end face side thereof, and as shown in FIGS. 2 and 9, a set screw 84 is provided in each screw hole 83. It is screwed through (79a, 79b, 80a, 80b), which achieves the fixing of the upper frame structure 12 to the rectangular plate 16A of the support plate structure 16.

When the lower frame structure 10 and the upper frame structure 12 are assembled as shown in FIG.
The tip of the tongue piece 65 of the annular body 62 is fitted into the hole 54 of the rod member 52R of the connecting means 52 as best shown in FIG. Therefore, as described above, the rolling wheel cylinder 60 is rotated by the rolling wheel portion 60, and the annular body 62 is moved to the rolling wheel cylinder 57.
When the ring-shaped body 62 is moved along the central axis of the right mount plate 34R and the left mount plate 34R.
L is also moved in synchronization. That is, the rotation of the wheel unit 60 adjusts the distances between the objective lens systems 31R and 31L and the eyepiece lens systems 33R and 33L, and thus the focusing operation of the pair of observation optical systems 30R and 30L is performed. Become.

With the tip of the tongue piece 65 fitted in the hole 54, the photographing section 12C has a pair of observation optical systems 30R.
And 30L, and is housed in a recess formed between the two. Further, in this state, the optical axis OS of the photographing optical system 67 is set at a position close to the plane P including the optical axes OR and OL of the observation optical systems 30R and 30L, that is, at substantially the same height position.

In this embodiment, a pair of observation optical systems 30R is used.
And 30L, for example, the objective lens systems 31R and 3R for the eyepiece lens systems 33R and 33L, respectively.
When the distance of 1L is the shortest, it is designed to obtain the focus of the observation object from 40 mail to infinity, and when observing the observation object from 2 meters to 40 meters, the eyepiece lens The observation object image is focused by separating 33R and 33L from the objective lens systems 31R and 31L, respectively. Of course, when the eyepiece lens systems 33R and 33L are separated from the objective lens systems 31R and 31L by the maximum distance, the focus of the observation object image 2 meters ahead is obtained.

In short, in the binoculars with a photographing function according to the present invention, the rotational movement of the roller wheel barrel 57 is compared with the pair of observation optical systems 30.
A part of the motion converting mechanism for converting into the focused motion of R and 30L is provided on the lower frame structure 10 side, and the other part is provided on the upper frame structure 12 side, and the lower frame structure 10 and the upper frame structure 12 are provided. At the time of assembling (FIGS. 2 and 9), both of these parts are engaged with each other, and thereby the motion converting mechanism is operated.

It is premised that the photographing optical system 67 has a pan-focus design so as to obtain a focus from a foreground subject at an appropriate distance to a distant object at infinity, and that photographing is performed only within the focusable range. If so, it is not necessary to incorporate a focusing mechanism in the lens barrel 58. However, in the present embodiment, the binoculars with a photographing function are photographed, for example, for the foreground subject two mail ahead, as in the case of a normal camera.
A focusing mechanism is also required for the lens barrel 58.

Therefore, in this embodiment, a helicoid screw is formed as a female screw on the inner peripheral wall surface of the roller wheel cylinder 57.
On the other hand, on the outer peripheral wall surface of the lens barrel 58, a helicoid screw that is screwed with the inner wall surface of the wheel barrel cylinder 57 is formed as a male screw. When the wheel barrel 57 rotates, the lens barrel 5
Since the rotation of 8 is blocked by the engagement of the key grooves (68a, 68b) and the pin elements (70a, 70b) as described above, the lens barrel 58 moves along the optical axis of the taking lens system 67. The moving direction depends on the rotating direction of the wheel cylinder 57. In short, both helicoid screws formed between the inner wall surface of the wheel barrel 57 and the outer wall surface of the lens barrel 58 convert the rotational movement of the wheel barrel 57 into a linear movement, that is, a focusing movement of the lens barrel 58. It will form a motion conversion mechanism for conversion.

The helicoid screw 61 formed on the outer peripheral wall surface of the wheel shaft barrel 57 and the helicoid screw formed on the inner wall surface thereof are opposite to each other, so that the wheel shaft barrel 57 mounts the eyepiece lens systems 33R and 33L. When rotated so as to be separated from the objective lens systems 31R and 31L, respectively, the lens barrel 58 is moved away from the CCD image pickup device 75, so that the light receiving surface of the CCD image pickup device 75 can be moved to a subject in a relatively short distance. It can be imaged in focus. Of course, the helicoid screw pitch on the outer peripheral wall surface of the wheel shaft cylinder 57 and the helicoid screw pitch on the inner peripheral wall surface thereof differ depending on the optical characteristics of the pair of observation optical systems 30R and 30L and the optical characteristics of the photographing optical system 67. It is supposed to be

In the above-described embodiment, in order to make the entire structure of the binoculars with a photographing function as compact as possible, the photographing optical system 67 is installed in the wheel wheel barrel 57, but in the present invention, the photographing optical system is used. 67 does not necessarily have to be installed in the wheel shaft cylinder 57, and in that case, the wheel shaft cylinder 57 can be configured as a slender solid wheel shaft.

As is apparent from the above description, in the assembling structure of the binoculars with a photographing function according to the present invention, a pair of observation optical systems is incorporated in the lower frame structure side, while one in the upper frame structure side. Since the imaging unit is incorporated, it is possible to assemble the lower frame structure and the upper frame structure independently for each function, and then by assembling the lower frame structure and the upper frame structure, Since the main structure is obtained, the whole manufacturing process can be simplified and made more efficient, and the manufacturing cost can be greatly reduced.

Further, according to the present invention, one part of the motion converting mechanism for performing the focusing motion of the pair of observation optical systems is provided on the lower frame structure side, and the other part is provided on the upper frame structure side. It is also an excellent feature that the lower frame structure and the upper frame structure are engaged with each other when they are assembled (FIGS. 2 and 9), whereby the motion converting mechanism is made to function. Become. That is, by distributing the complicated motion conversion mechanism to the lower frame structure and the upper frame structure, the difficulty of each independent assembling work of the lower frame structure and the upper frame structure is averaged, and therefore, the photographing is performed. The overall assembly efficiency for functional binoculars will be improved.

Furthermore, when the photographing optical system is installed in the wheel barrel, the entire structure of the binoculars with a photographing function can be made compact. Since the wheel portion of the binoculars is given a relatively large diameter so that it can be easily rotated by an observer's finger, the rotation shaft of the wheel portion serves as a wheel barrel for installing the photographing optical system. Even if formed, the overall structure required to fulfill the function as binoculars is not significantly bulky.

Further, when the photographing optical system is housed in the recess formed between the pair of observation optical systems, the binoculars with a photographing function can be formed thinner, and the space between the observed image and the photographed image can be reduced. The parallax can be reduced.
