Abstract
A miniature projector relates to a teaching aid. The miniature projector comprises a driven film rotation disc arranged above a frame of the projector, a drive film rotation disc below the frame, a rotary handle connected with a shaft end sheathed in the drive film rotation disc, a lamp case arranged between the two film rotation discs of the projector, a light condensing hole formed on the front side of the lamp case, a case cover with a reflecting mirror mounted on the rear side of the lamp case, a highlight lamp connected with the lamp case through the case cover, and a projection lens placed in front of the light condensing hole of the lamp case. The miniature projector has the advantages of simple structure and low cost, and can directly show the principle of the projector to reinforce the understanding and memory of students.
Description
Technical field:
The utility model relates to a kind of teaching aid.
Background technology:
Along with the progress in epoch, televisor has all been arranged in the classroom of primary school, but the ultimate principle of cinema screening film has also been needed to do comprehensive instruction, except on blackboard, explaining, with regard to neither one teaching aid intuitively.
Summary of the invention:
The purpose of this utility model is that a miniature projector will be provided.Miniature projector is to establish passive film rotating disk above the projector framework, initiatively film rotating disk is established in the below, cover is inserted initiatively, and the axle head of film rotating disk connects turning handle, a lamp box is established in the centre of two film rotating disks of projector, convergent hole is established in the lamp box front, a case lid that reflective mirror is housed is established in the lamp box back, can connect a major light by case lid in lamp box; A projection lens is placed in the place ahead at the lamp box unthreaded hole.During use, on passive film rotating disk, roll up film to be shown, head are emitted downwards by unthreaded hole be connected with film rotating disk initiatively.Can move down film so shake handle; And film is when the unthreaded hole, and the picture of film can pass through projection lens, and picture is projected on the calico curtain, can supply to watch.Miniature projector simple in structure, price is cheap, but can strengthen student's understanding and memory with the principle of projector from intuitively seeing clearly.
Miniature projector is to establish passive film rotating disk above the projector framework, initiatively film rotating disk is established in the below, cover is inserted initiatively, and the axle head of film rotating disk connects turning handle, a lamp box is established in the centre of two film rotating disks of projector, convergent hole is established in the lamp box front, a case lid that reflective mirror is housed is established in the lamp box back, can connect a major light by case lid in lamp box; A projection lens is placed in the place ahead at the lamp box convergent hole.
The beneficial effect that adopts miniature projector is the simple in structure of miniature projector, and price is cheap, can strengthen student's understanding and memory with the principle of projector from intuitively seeing clearly.
Description of drawings:
Fig. 1 is the structural representation of miniature projector.
Embodiment:
