Abstract

PURPOSE:To improve the operability by providing a means sliding onto a board to erase a character or a graph drawn on the board thereby erasing the character or graph without manual operation. CONSTITUTION:A character or graph is drawn on an endless belt form board 1, a switch 4 is operated to forward a motor 3 and to activate a memory 6, the board 1 is turned in the direction A, fed under a reader 5 such as an image sensor, the character or the like is read by the reader 5, stored tentatively in the memory 6 and printed out by a printer 7. In forwarding or reversing the motor 3 to turn the board 1 in the direction A or B so as to be slided onto an eraser 8 where a felt or the like including water and a solvent is pressed into contact with the board 1 thereby erasing the character or the like drawn on the board 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic blackboard having a function of copying characters, figures, etc. drawn on a boat.

Conventional technology Conventionally, this type of electronic blackboard uses a reading device such as an image sensor to read characters and figures drawn on a rotatable board, and prints out the read characters using a printer, etc. Ta.

Problems to be Solved by the Invention However, in the above configuration, the characters and figures drawn on the board had to be manually wiped with a blackboard eraser made of felt, etc., resulting in poor operability. It wasn't a good electronic device.

Means for Solving the Problems In order to solve the above problems, the present invention provides means for slidingly contacting a board rotated by a driving member to erase characters, figures, etc. drawn on the board. It is characterized by:

Effects of the Invention According to the above-described structure, the characters, figures, etc. drawn on the board that have passed through the erasing means are erased, so that the operability of the electronic blackboard is improved.

Example Hereinafter, the present invention will be described in detail with reference to the drawings.

The attached drawing is a schematic configuration diagram of an electronic blackboard showing an embodiment of the present invention, and the board 1 is configured in the shape of an endless belt,
It is wound around axes 2a and 2b. Axis 2b is connected to a motor 3, so that board 1 can be rotated about axes 2a and 2b by means of a drive member, namely motor 3. Incidentally, the motor 3 can be rotated forward and backward by a switch 4.

A reading device 5 such as an image sensor is arranged on the shaft 2a side of the board 1, and an output terminal of the reading device 5 is connected to a memory 6.

The memory 6 is connected to the switch 4, and when the switch 4 causes the motor 3 to rotate forward and the board 1 to rotate in the direction shown in the figure, the memory 6 operates and reads the characters and figures drawn on the board 1. The calligraphy and drawing information such as the above is read by the reading device 5 and stored in the memory 6, and then printed out by the printer.

On the other hand, felt or the like is placed on the shaft 2b side of the board 1.
An erasing device 8 is disposed in contact with the felt, and this felt contains water or ink depending on the type of ink (water-based or oil-based) used by the pen used to draw on the board 1.

In the above configuration, after drawing desired characters, figures, etc. on the board 1, the switch 4 is operated to rotate the motor 3 in the normal direction and operate the memory 6. Then, the board 1 is rotated in the direction A in the figure and sent under the reading device 6, and the characters etc. drawn on the board 1 are read by the reading device 5, and the read characters etc. are temporarily stored in the memory 6. After that, the printer 7 prints out the data.

In addition, if you want to look again at the characters drawn on the board 1 that has passed under the reading device 5, operate the switch 4 to turn the motor 3
is reversed and the board 1 is moved in the direction B shown in the figure. At this time, since the memory 6 is not driven by the operation of the switch 4, the printer 7 does not output any printout.

Next, when erasing characters drawn on the board 1, the motor 3 is rotated forward or reverse to rotate the board 1 in the direction A or B in the figure, and the board 1 is brought into sliding contact with the erasing machine 8.

Note that if the portion of the eraser 8 that contacts the board 1 is configured to rotate in the opposite direction to the direction of rotation of the board 1, the erase function will be further improved.

In the embodiment described above, the memory θ is configured to operate whenever the motor 3 is rotated forward and the board 1 is rotated in the inward direction, but the memory 6 may be configured to operate only when desired. In this case, the amount of paper ejected from the printer 7 can be saved.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, characters, figures, etc. drawn on the board can be erased with an extremely simple configuration, and operability is improved.
