Abstract

PURPOSE:To realize many times of output of the display once shown on the surface of a blackboard by using a plotter which can store the information on the blackboard and regenerate it on the blackboard as a screen. CONSTITUTION:The titled blackboard is provided with a coder 13 to code the picture information read by a reader 1 together with a floppy disk 4 (memory) which stores the coded picture information, and a plotter 5 which regenerates the picture information on the novel surface of a blackboard. The characters, etc., displayed on the surface 6 are read by the reader 1 and the picture information is coded by the coder 3. This coded information is stored in a memory 4. When the characters, etc., once erased are regenerated, a writing tool held by the plotter 5 is pressed onto the surface 6 and then moved so that the memory contents of the memory 4 are regenerated on the surface 6. In such a constitution, the characters, etc., once written on the blackboard can be regenerated freely as desired.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electronic blackboard used for meetings and the like.

In particular, it relates to an electronic blackboard that encodes, stores, and reproduces information in characters and figures displayed on the blackboard.

〔overview〕

The present invention provides an electronic blackboard that reads characters and figures on the blackboard and outputs them on paper using a copying machine, and is provided with plotter means that can store information on the blackboard surface and reproduce the stored information as a screen on the blackboard surface again. This makes it possible to output characters and figures once displayed on a blackboard many times, and also to output time-scheduled screen information that has been input in advance.

[Conventional technology]

FIG. 2 is a block diagram showing the configuration of a conventional electronic blackboard. Conventional electronic blackboards use a reader to read the characters and figures on the blackboard, and print them out on paper using a copier.

[Problem that the invention seeks to solve]

The above-mentioned conventional electronic blackboard has the disadvantage that, because characters and figures are written on the blackboard surface by hand, it is impossible to reproduce the screen once it has been erased.

An object of the present invention is to solve this problem and provide an electronic blackboard that can reproduce characters and figures once written on the blackboard surface many times.

[Means for solving problems]

The present invention provides an electronic blackboard equipped with a reader that reads screen information and a copying machine that outputs the screen information on paper, and an encoder that encodes the information read by the reader, and an encoder that encodes the information read by the encoder. The present invention is characterized by comprising a storage device that stores converted information, and a plotter that reproduces a screen on a blackboard surface based on the information stored by the storage device.

[Effect]

When copying to play back a screen that has been erased,
It encodes the read information, stores the encoded information, and outputs the stored information again.

Through this operation, characters or figures once displayed on the blank surface are reproduced on the blackboard surface many times, and by inputting information on the scheduled screen, various standardized screens can be reproduced on the blackboard surface. be able to.

〔Example〕

Next, an electronic blackboard according to an embodiment of the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the structure of an electronic blackboard according to an embodiment of the present invention, and FIG. 3 is a perspective view of the electronic blackboard according to an embodiment of the present invention.

The electronic blackboard according to the embodiment of the present invention includes a reader 1 that reads screen information, and a copier 2 that outputs the read screen information on paper.
The present invention further includes an encoder 3 that encodes the screen information read by the reader 1, and a storage device (floppy disk) 4 that stores the screen information encoded by the encoder 3. and a plotter 5 that reproduces the screen on the blackboard surface based on the information stored in the storage device (floppy disk) 4.

In the electronic blackboard according to the embodiment of the present invention configured as described above, the characters or figures displayed on the blackboard surface 6 are read by the reader 1 provided within the blackboard surface 6, and the characters or figures displayed on the blackboard surface 6 are read by the encoder provided on the blackboard as screen information. The encoder 3 encodes the screen information and sends it to a storage device (floppy disk) 4 where it is stored.

When you want to reproduce erased characters or figures on the blackboard surface, by providing reproduction support, the block holding the writing instrument (for example, a felt-tip pen, etc.) presses the writing instrument onto the blackboard surface, moving vertically and horizontally. By the movement of , characters or figures stored in the storage device (floppy disk) 4 can be reproduced on the blackboard surface.

Characters and diagrams once written on the blackboard surface can be reproduced many times, and can also be displayed on another sheet of paper using the copier 2. Also, screen information such as a map of Japan can be memorized in advance. By doing so, you can reproduce it as many times as necessary.

〔Effect of the invention〕

As explained above, the present invention stores information on the blackboard surface, and further outputs the stored information onto the blackboard surface again, so that characters or figures once written on the blank surface can be written on the blackboard surface many times. There is an effect that can be reproduced.

In addition, by inputting information on a specific screen (such as a map of Japan) into the storage device (floppy disk) in advance,
This has the effect of allowing a variety of standardized screens to be output on the blackboard.
