Abstract

The invention relates to a mini projection device, and discloses a mini projection device. In the mini projection device, one side of a mini projection structural body is connected with a screen combined body; when the mini projection device is used, the mini projection device can slide, a screen body can rotate to be vertically erected from the screen combined body first and then be expanded. Therefore, the screen on which the images are projected can be integrated on the mini projector in a portable mode, so that the stable projection can be realized under various environments so long as a user carries the mini projector.

Description

technical field [0001] The present invention relates to a micro-projection device, in particular to a micro-projection device with an external structure (similar to a casing) capable of stable projection in various environments. Background technique [0002] A projector is an electronic device that uses a light source, a light modulator, and a projection lens to reproduce a small image, and then enlarges and projects the image. Projectors are generally used in offices. They are large in size and heavy in weight. They are usually placed in the center of the office or hoisted for use. Although there are also miniaturized projectors being commercialized, they are not as portable as mobile phones or Personal Digital Assistants ("PDA"), so they are basically not used in non-important meeting occasions. [0003] In response to these needs, the inventors of the present invention are developing a miniature projection device whose length and width are the same as those of a credit c...
