Abstract

PURPOSE:To permit quick, sure and smooth viewing of the erecting image of an object when an eyepiece lens system is viewed from a desired deflection turning position, by deflecting a deflection prism and a deflection roof type erecting prism relatively. CONSTITUTION:An erecting prism system 3 is disposed with a deflection prism 4 a deflection roof type erecting prism 5 by facing these prisms to each other. The prism 4 has only the effect of curving the optical axis 45 deg. and does not contritute to the inverting or erecting of images. The prism 5 curves the optical axis 45 deg. and inverts the images vertically and laterally.The image from an objective lens system 7 advances while the same is transmitted, reflected and curved by the respective faces in the prism 4 and the prism 5 as shown by the arrow, and is outputted from the system 2, whereby the erecting image is observed.

Description

DETAILED DESCRIPTION OF THE INVENTION The apex angles of the present invention are 45°, 22.5° and 11°.
2.5°, and one declination prism with a gold-plated surface opposite to its 45″ apex angle;
67.5° and 67.5°, and the surface opposite to the 45° apex angle is roof-shaped, and is opposed with a total air gap, and the relative angle of the angled roof-shaped prism is By appropriately rotating the angle around the optical axis, it is possible to freely select the viewing angle, in other words, the clear viewing position when viewing the entire object by looking through the optical lens system. This article concerns a telescope that was extremely convenient for practical use.

In the prior art, it is known that a combination of one deflection prism and one deflection roof prism is used in a direct-viewing telescope or binoculars.

Further, a lens barrel type having a roof-shaped prism or a combination of a plurality of prisms with an angle of 45° or l'i90° is also known.

However, even in the case of a fall, there is a drawback that viewing angles other than predetermined angles cannot be used.

The present invention relates to a novel telescope that improves the conventional drawbacks, and its features include the relative angles of one deflection prism and one deflection roof prism, with the opposing surfaces [bath The point is that the idea of appropriately rotating the declination angle is introduced, and the dvc will be explained below.

Book 4! In this example, the same parts as in the first and second examples have the same number Zenmachi (7).

This embodiment shows a case in which the eyepiece lens system 2 is tilted to an appropriate position, and the deflection angle prism 4 and the deflection roof-shaped IF vertical prism 5 are integrally connected to the light i1m 6 vc pair [~appropriate deflection angle]. II! The deflection prism 4 and the deflection roof-shaped erecting prism 5 are deflected (141rJ1) as appropriate along the opposing surface PK with the light Ill6 as the center.

Therefore, 1g from the pair's proboscis system 1: As shown by the ir arrow, at the deflection prism 4 and the deflection roof-shaped erect prism 5, the reflection/+'it 4]r is reflected, respectively. Proceed carefully and take L as appropriate! An erect image is output from the eyepiece system 2 located at J and is viewed at 7L.

Fourth embodiment (Figure 7) V stuck.

In this example, the same parts as the first to third Nori examples have the same aroma as pf sushi.

This embodiment is an actual example of the first embodiment 1+I+ fully realized, and shows the case of direct viewing.

Reference numeral 7 denotes a first cylindrical body that includes the entire objective lens system 1, and is integrally formed by combining 9 with a second cylindrical body 8 that has a deflection prism 4. 10 includes 11 tightening screws, a ring body and a cylindrical body 8
When the tightening screw 11 is fully loosened, the cylindrical body 8
