Abstract

The invention discloses an all-light-path projection shading describing instrument, and aims at providing an improved all-light-path projection shading describing instrument. The all-light-path projection shading describing instrument comprises a theodolite and a telescope, wherein the theodolite is used for adjusting the longitude and the latitude; the telescope is arranged on the theodolite; the telescope comprises an objective lens and a corner ocular lens; the corner ocular lens is arranged at the rear end of the objective lens; the all-light-path projection shading describing instrument is characterized in that a zenith positive light projection lens is also arranged at the rear end of the objective lens and is sleeved with a bucket-shaped projection opaque chamber; a cover board is arranged above the bucket-shaped projection opaque chamber; and a permeable projection describing plate matched with the zenith positive light projection lens is arranged on the cover board. A distant image can be projected to the projection describing plate through a corresponding light path, so that describing covered with a paper or direct photographing is facilitated; and the all-light-path projection shading describing instrument has the characteristics of ingenious structure, low cost and wide adaptability.

Description

technical field [0001] The invention relates to a pictorial instrument, in particular to an all-optical path projection light shielding pictorial instrument. Background technique [0002] Most of the current telescopes can only directly observe distant objects. When you need to take pictures, you need to add a special adapter to connect the camera. However, different cameras have different interfaces, so they need different interfaces. However, some mobile phones with camera functions do not. It is convenient to connect and take pictures; in addition, the objects observed by the telescope cannot be drawn directly with a pen, which is inconvenient for the unique requirements of drawing pictures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an all-optical-path projection light-shielding photo instrument, which can effectively solve the problem of inconvenient drawing and taking pictures, and has the characterist...
