Abstract

The invention discloses a slide projector comprising an enclosed cavity. The enclosed cavity is provided with an imaging aperture. A intense light source and a fan are arranged inside the enclosed cavity. The slide projector is characterized in that: A reflecting mirror (4) is arranged between an inner wall of a side, close to the imaging aperture (5), of the enclosed cavity (1) and the intense light source (3). The inner wall of the other side of the enclosed cavity (1) is provided with a material rack (8). Materials (2) are movably installed on the material rack (8). According to the invention, any printing material such photos, newspapers, pictures and manuscripts can be used as the materials. Through regarding optical principles as bases, problems of limitations and high costs of old-fashioned slide projectors are overcome. The slide projector of the invention overcomes limitations of films of the old-fashioned slide projectors, and is a convenient, practical, and reliable demonstration tool.

Description

technical field [0001] The invention belongs to the field of entertainment and educational appliances, in particular to a simple and practical imaging projection device. Background technique [0002] A hundred years ago, humans created slide projectors, which have always been a good tool for educational demonstrations and entertainment, but relatively speaking, the structure is complicated and the price is high. A special film is required to form an image, which is troublesome and more costly, and it cannot play images as one likes. It is limited to film and cannot become an entertainment device for everyone. Contents of the invention [0003] The object of the present invention is to provide a slide projector to solve the problem that the existing slide projector is only limited to films and has high cost. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A slide projector, comprising an airtight cavity, an...
