Abstract
The utility model provides a multipurpose light imaging apparatus which is composed of a picture screen cover, a convex lens and a picture picking barrel. The utility model is characterized in that the convex lens is fixed in the picture picking barrel, a section of telescopic pipe is connected between the picture picking barrel and the picture screen cover, and simultaneously, the center of the picture screen cover is provided with a picture screen. The utility model has the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of multi-usage photoimaging device, belongs to the optical imagery class, is particularly useful for primary school teaching and uses.
In the natural section of primary school imparts knowledge to students in the past, when telling about light pinhole imaging system knowledge, often need just can reach the teaching purpose of pinhole imaging system by the cooperation of a plurality of utensils.The sort of combined demonstration means are the Taiyuan beginning both, and is difficult to very reach intuitively teaching purpose again.
The purpose of the present utility model: aim to provide a kind of multi-usage photoimaging device, wish that it is simple in structure, easy to operate, can very show the pinhole imaging system principle clearly.
This multi-usage photoimaging device is by picture screen cover (1), convex lens (2) and adopt picture tube (3) and form, it is characterized in that: described convex lens (2) are fixed in to be adopted in the picture tube (3), between adopting, connecting one section telescopic tube (4), be provided with picture screen (5) at the center of picture screen cover (1) simultaneously as tube (3) and picture screen cover (1).
This multi-usage photoimaging device according to above method design, relatively simple for structure, not only show the pinhole imaging system principle in primary school's photoimaging teaching intuitively, but also can introduce essential structure principle and the human eye's vision and the aufbauprinciple of camera, reach multi-use.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, picture screen cover 2, convex lens 3, adopt picture tube 4, telescopic tube 5, picture screen.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
The round plastic cylindrical shell that the inventor adopts a diameter at butt end 80mm, top diameter 70mm as picture screen cover (1), at the huge pillar circle of this picture screen cover (1) and on open a diameter 35mm aperture as picture screen (5), this screen can be made of tracing paper; Adopt as the useful luminous flux road between tube (3) and the picture screen cover (1) as connection with a telescopic hollow rubber pipe simultaneously; Convex lens (2) then are fixed on to be adopted in the picture tube (3), perhaps also can be between draw-tube (4).Here it should be noted that must keep adopting picture tube (3), telescopic tube (4) is concentric with picture screen (5) center.
In actual use, adopt picture tube,, observe the variable condition of imaging on promptly can picture screen along with elongating or shortening of telescopic tube (4) as long as horizontal direction moves.The teaching purpose that also shows this imager thus.
