徴とする電子黒板装置。[Scope of claim for utility model registration] A writing sheet on which images can be written and erased, and which has a length equivalent to multiple screens;
Two rotatable winding and unwinding shafts arranged in parallel so that the writing sheet can be stretched and held for the length of the screen, a light source that illuminates the writing sheet, a lens, a light receiving element, etc. a reading means, a memory for storing image data read by the reading means, and a recording means for recording on a medium such as paper, and the writing sheet is wound on one of the two winding and feeding shafts. At the same time, by feeding out the writing sheet from the other side, the writing sheet is conveyed, and the writing sheet is illuminated by a light source, and the reflected light is received by the light receiving element by the lens of the reading means, so that writing can be performed. In an electronic whiteboard device that sequentially reads image data written on a blank sheet and stores it in a memory, and records the image data from the memory on a medium such as paper by a recording means, the number of light sources is two, These two light sources are arranged so that they can respectively illuminate the writing sheet on the two winding and feeding shafts, and the first one from one side of the two winding and feeding shafts
A half mirror is provided that transmits the reflected light from the second side, reflects the second reflected light from the other side, and allows the transmitted light and the reflected light to be received by the light receiving element of the reading means through the same optical path. . An electronic whiteboard device, characterized in that an address generator is provided that can specify either the first address or the last address of the memory when storing image data.
