[Prior art]

 Although phantom lamps and projectors are indispensable display devices at medium and large conferences and study meetings, they have some drawbacks. First, phantom lamps have been used for display of image data (film for phantom lamps), etc., and the image data is made from film positive taken by a camera and then set on the phantom lamp. It is displayed on the screen by the projection method. Projection projectors are basically the same in principle as phantom lamps, but in recent years, projection display devices combined with computer equipment have appeared, which project a computer screen directly onto a large projector screen. It is. This type of display device has obviously improved data management and display quality as compared with a conventional projector.

[Problems to be solved by the invention]

 However, the conventional illuminator has the following disadvantages. 1. When a conventional illuminator is used, it is necessary to perform a photographic development process, which takes time, is complicated, and is not practical. 2. Since the image data is a phantom light film, it requires a considerable amount of space to store it, and has poor durability.For example, if the storage environment is not ideal, mold will be generated and adversely affect the phantom light film Will be given. Further, the conventional projector has the following disadvantages. 1. A conventional projector has a computer body and projection equipment, and has a very large volume, which makes it difficult to carry and requires a considerable amount of space at the site of use. 2. Although the display device does not include a computer main body, it has a special structure and expensive projection equipment, so that the cost is very high and it is difficult to spread it in small and medium meetings. 3. Since the computer system of the projector is a precision device, it may be damaged during transportation. 4. Operators must be familiar with the operation of computers and projection equipment, and the operation is too difficult for ordinary people. 5. It is easy to copy confidential contents in the computer system in which the image data is recorded.
