Abstract

PURPOSE:To enable a table using a same background or the like to be easily drawn or reproduced by a method wherein a second recording board having a transparent recording surface to which a window part is provided, is arranged outside a first recording board having a white recording surface. CONSTITUTION:For a first recording board, a plurality of white recording surfaces are annularly connected. A first feed roller 3 together with a roller 5 supports and conveys the recording board 1. For a second recording board 2, a plurality of transparent recording surfaces are annularly connected, a window part 11 in which at least one transparent recording surface is omitted is established, and paintings and calligraphic works can be recorded on the white recording surface of the recording board 1. A second feed roller 4 together with a roller 6 supports and conveys the recording board 2. First and second driving parts 7, 8 receive source power from an operation part 9 and drives the feed rollers 3, 4 to be rotated. By this structure a reproduction part 10 reads simultaneously a background recorded on the recording surface of the recording board 1 and the printings and calligraphic works drawn on the recording surface of the recording board 2 and can output printed recording paper.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic blackboard, and particularly to an electronic blackboard for copying and outputting calligraphy and drawings written on a white board.

[Conventional technology]

Electronic blackboards use facsimile technology to read calligraphy and drawings drawn on a blackboard at a meeting or the like and copy them onto recording paper.

FIG. 3 is a block diagram of an example of a conventional electronic whiteboard.

The operation section 9a supplies power to the first drive section 8a by operating a switch. The first drive section 8a drives the feed roller 3a. The feeder 1 collage 3a, together with the guide roller 5a, supports and moves the writing board 1a, which has a plurality of writing surfaces and is connected in an annular manner.

The copying section 10a reads the calligraphy and drawings drawn on the writing surface, prints them on a recording paper, and outputs them.

[Problem to be solved by the invention]

In the above-mentioned conventional electronic blackboard, when writing based on the same background (for example, ruled lines) of a diagram or the like on each side of the writing board 1a, the background must be written many times each time the writing surface changes. 9 An object of the present invention is to provide an electronic blackboard that does not require drawing the same background over and over again.

[Means to solve the problem]

The electronic blackboard of the present invention includes a first writing board in which a plurality of white writing surfaces are connected in a ring, a first feeding roller that supports and conveys the first writing board, and a plurality of transparent writing surfaces. a second writing board connected in an annular manner and provided with a window portion in which at least one of the transparent writing surfaces is removed and arranged outside the first writing board; and a second writing board that supports and conveys the second writing board. 2 feed rollers, and first and second feed rollers that drive the first and second feed rollers.
It has a drive unit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a perspective view for explaining the embodiment. This will be explained with reference to FIGS. 1 and 2.

The first writing board 1 connects a plurality of white writing surfaces in a ring shape. The first feed roller 3 supports and conveys the first writing board 1 together with the roller 5 .

The second writing board 2 has a window 11 in which a plurality of transparent writing surfaces are connected in a ring and at least one transparent writing surface is deleted, and calligraphy and drawings are written on the white writing surface of the first writing board 1. can.

The second feed roller 4 supports and conveys the second writing board 2 together with the roller 6.

The first and second driving sections 7.8 receive power from the operating section 9 and drive the first and second feed rollers 3, 4 to rotate.

In this way, the background written on the writing surface of the first writing board 1 and the calligraphy and drawings drawn on the writing surface of the second writing board 2 can be transferred to the copying section 1.
It is possible to output recording paper on which 0 is printed at the same time.

〔Effect of the invention〕

As explained above, the present invention provides a first writing board with a white writing surface and a second writing board with a transparent writing surface provided with a window on the outside, thereby making it possible to use the same background. It has the effect of allowing tables and the like to be easily drawn and copied.
