As a prior art, there is Utility Model Publication No. 54-3711. The focus adjustment method of the two-axis binoculars shown here is to provide a thin sliding axis on the rotation center of the two rotation axes for the left and right mirrors, which are held on the substrate so as to rotate relative to the substrate. , through which the objective lens is moved.
また、他の従来技術として実開昭55−6928号が

Therefore, the two-axis binoculars of Utility Model Publication No. 54-3711 have 2
Since the objective lens movement axis passes through the rotation centers of the two rotation axes, the structure is complicated and the cost is high.
Additionally, since the transmission mechanism is built into a narrow space, the holes and shafts have to be thin, making machining and precision difficult. Furthermore, in the dual-axis binoculars disclosed in Japanese Utility Model Application Publication No. 55-6928, a portion of the focusing device is exposed to the outside, making it susceptible to contamination and damage and prone to malfunction. Furthermore, exposing the conductive movable part is not desirable in terms of external design, and requires a certain amount of exterior surface treatment, which increases costs.
そこで本考案は、外観デザインの優れた製造容
易で低コストの双眼鏡を提供することを目的とす

The right mirror body 1 and the left mirror body 2 have bearing protrusions for bearings formed near their central portions, and are fitted into bearing recesses formed on the left and right sides of a flat substrate 3, respectively. Right mirror body 1
and the left mirror body 2 are steel balls 4, 4' and a bearing screw 5, which are disposed between the four opposing surfaces of the left and right mirror bodies 1, 2, a bearing convex portion and a bearing concave portion, which face each other in the optical axis direction.
It is rotatably attached to the substrate 3 via 5'.
The focusing knob 6 is located in a rectangular hole 3b of the substrate 3 with limited axial movement, and a lead shaft 7 screwed into the focusing knob 6 is fitted into a guide hole 3a of the substrate 3. As a result, the lead shaft 7 moves straight by rotating the focusing knob 6. Further, a connecting member 8 is attached to the lead shaft 7 with a screw 9. The objective lens barrels 11, 11' are fitted into the right lens body 1 and the left lens body 2, respectively, with the objective lenses 18, 18' fixed by a retaining ring 12. The ends of the objective lens barrels 11 and 11' are penetrated through the right lens slot 1a formed in the bearing convex portion of the right lens body 1 and the left lens body slot 2b formed in the bearing convex portion of the left lens body 2. The connecting shafts 10, 10' are fixed. The connecting member 8 and the connecting shafts 10, 10' are connected by grooves 8a formed in the connecting member 8,
8b, the left and right mirror bodies 1 and 2 are connected so as not to come off even if they are opened and closed (by rotation by the steel balls 4 and 4' and the bearing screws 5 and 5'). The prism 19 and the eyepiece 20 are the eyepiece member 1
7 and is attached to the left and right mirror bodies 1 and 2. The right mirror cover 13 and the left mirror cover 14 are
They are each made of rubber, and are bonded after being placed over the right mirror body 1 and the left mirror body 2, respectively. The board cover 15 is also made of rubber, and is bonded after covering the board 3. The left and right mirror covers 13, 14 and the board cover 15 are made with appropriate cuts or divided so that they can be easily covered. At this time, the board cover 15 that covers the upper and lower surfaces of the board 3 is formed to protrude over the left and right bearing recesses, and when the distance between the left and right mirror bodies 1 and 2 is the smallest, the bearing convexity of the left and right mirror bodies 1 and 2 is formed. The covers 13 and 14 on the top surface cover the top surface of the board 3.
When the distance between the left and right mirror bodies 1 and 2 is the largest, the covers 13 and 14 on the lower surfaces of the bearing convexes of the left and right mirror bodies 1 and 2 are located inside the cover 15 that covers the lower surface of the board 3. The size of each is determined as shown in . Note that the lid 16, which also serves as a board cover that covers the bottom surface of the board 3, is used to cover the bottom surface of the board 3 after the mechanical part is assembled.
is glued to. A perspective view of the binoculars thus obtained is shown in FIG.

動して焦点合せが行なわれる。 The operation will be explained below. To adjust and fold the eyelids, the left and right mirror bodies 1 and 2 are rotated to open and close using steel balls 4 and 4' and bearing screws 5 and 5'. The maximum and minimum opening and closing times (the maximum and minimum spacing between the lens barrels 1 and 2) are regulated by substrate limits 3c and 3C'. On the other hand, focus adjustment is performed by rotating the focusing knob 6. That is, when the focusing knob 6 is rotated, the lead shaft 7 moves straight in the optical axis direction of the left and right lens barrels 1 and 2, and connects the objective lens barrels 11 and 1 via the connecting member 8 and the connecting shafts 10 and 10'.
Objective lenses 18, 18' fixed at 1' are moved to perform focusing.

According to the present invention, the focusing device, the mirror body, the substrate, and the rotation guide member, excluding the focusing operation member, are not exposed to the outside by opening and closing the left and right mirror bodies, and are housed within the cover member with a simple structure. Since the binoculars can be stored in the bin, it is possible to provide low-cost binoculars with an excellent external design.
