Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic whiteboard device capable of printing out images and the like on a sheet.

2. Description of the Related Art Electronic blackboard devices have been developed that allow minutes of conventional technical conferences to be written on a sheet using a water-based felt-tip pen, etc., and the resulting image is printed out on recording paper, and has been attracting attention.

Problems to be Solved by the Invention However, the conventional method had the following problems. That is,
The chalkboard surface was whitish, which caused eye strain and made it difficult to read the text. The present invention solves these problems.

Means for Solving the Problems and the present invention achieves the above object by forming a sheet from a reinforcing sheet portion, a paintable sheet, and a dark color paint layer such as deep green or black.

Effect: According to the above method, characters etc. are written on the dark paint layer, so the eyes are not tired, and in this case, the writing is done on the sheet using a whitish writing medium such as chalk, but in that case, erasing is difficult. Even if it's not perfect, it doesn't bother me that much,
This reduces eye fatigue and difficulty in reading characters.

Example In Fig. 1, 1 is a housing, 2 is a sheet, and the surface is dark green or black, and although this surface is a painted surface, it is suitable for the uneven treatment of the underlying sheet. It has a certain roughness. 3 is the choke holder. 4 is an operation switch board. Reference numeral 5 denotes a print paper discharge port, which is a paper discharge port for printing out the contents written on the sheet 2.

6 is a column, 7 is a caster, and 8 is an electric box.

FIG. 2 is a diagram of its internal structure, and 26 is a motor that rotates the loop-shaped sheet 2. 27a.

27b is a roller that serves to rotate and move the sheet 2 smoothly. A fluorescent lamp 17 illuminates the contents written on the sheet 2 and reads them through a lens 19 with a photoelectric conversion element 20. 21 is a printed board equipped with a photoelectric conversion element,
24 is a connector wire, 22 is a printer, and 23 is paper being ejected.

At this time, the sheet 2 is constructed by laminating a film 33 coated with a dark green paint layer 34 to a black polyester film 32 used as a reinforcing note part, as shown in FIG. Furthermore, if a high quality paint with high viscosity is developed, the film 32 can be directly coated with dark green paint. Note that the sheet 33 exhibits some cushioning effect and prevents the paint layer 34 from peeling off when it is bent. Also, use white or yellow felt tips to fill in the notes.

Effects of the Invention According to the present invention, since the surface of the sheet is dark-colored, it is possible to use conventional means used for ordinary blackboards, such as chalk, for writing, so problems such as the inability to use the sheet because there is no writing means can be avoided. Since there are no scratches or shine on the sheet surface, a calm atmosphere can be created, and characters can be easily seen, preventing eye fatigue.
