Description

DETAILED DESCRIPTION OF THE INVENTION [Field of use of the cow flr1] The present invention relates to an electronic blackboard on which writing on the writing surface, \, and other instructions can be performed at a position 1i away from the writing medium.

[Conventional technology]

In conventional electronic blackboards, writing is performed on the writing surface of a writing medium using a writing instrument, or erasing is performed using an erasing tool. Therefore, for example, when holding a meeting with a large number of people, either a specific person should be at the blackboard as a scribe, or an unspecified person should go to the electronic blackboard each time to write or erase. I was trying to do it.

[Problem that the invention seeks to solve]

On conventional electronic blackboards, writing was done using a writing instrument or erasing was done using an eraser, so when holding a meeting with a large number of people, each person's comments were recorded on the writing surface of the blackboard. :M Entering information or erasing and rewriting may impede the progress of the meeting.

Therefore, an object of the present invention is to provide a computer that can be used for writing and writing at a distance from a writing medium.
writing on the surface and giving other instructions;
An object of the present invention is to provide an electronic blackboard that enables each person to immediately write or rewrite their opinions on a writing surface during a meeting, etc., thereby promoting the efficiency of meetings, etc.

[Means for solving problems]

The inventive electronic blackboard uses an input device provided separately from the writing medium to issue various instructions, and operates the scanner, writing device, erasing device, reading device, and printer as appropriate based on the input information. It is intended to make it possible.

[Effect]

A scanner, writing device, erasing device, reading device, and printer operate based on information inputted by the input device, and writing, erasing, printing, etc. can be performed at a position away from the writing surface.

〔Example〕 An embodiment of the present invention will be shown below.

FIG. 1 is an external view of the electronic whiteboard, and numeral 1 in the figure is a medium support body formed by attaching a square frame 1b to movable support legs 1a. A sheet-like writing medium 2 is supported by the square frame 1b. The writing medium 2 has a loop shape and is suspended between upper and lower guide shafts 3 and 4 that are provided parallel to each other as shown in FIG. The upper guide shaft 3 is rotated by a pulse motor 5 that is a driving source, and the rotation of the guide shaft 3 allows the writing medium 2 to be moved in the vertical direction.

A reading section 6 is provided behind the writing medium 2, as shown in FIG. 2, and a printer section 7 is provided roughly on the back side of the square frame 1b.

The reading unit 6 irradiates a writing medium 2 moving at a constant speed with a beam of light having a width equivalent to the entire width of the medium 2 from an oblong light emitter 8 at a constant angle, and further reflects the reflected light with a mirror 9. The reflected light is guided through a slit 10 and a lens 11 to a photoelectric converter (COD) 12, where the written information on the writing medium 2 is optically read and output as an electrical signal to the printer section 7. Note that the reading section 6
operates only while the recording medium 2 is being moved upward at a constant speed by a constant amount (half a rotation) when viewed from the back side.

On the other hand, the printing unit 7 is, for example, a thermal printer equipped with a thermal head 14, and upon receiving the read signal from the photoelectric converter 12, pulls out the paper 16 from the paper holder 15, supplies it to the thermal head 14, and prints there. After this, the cutter 17 is operated to discharge the printed paper 16 of a certain size to a vapor receiver 18 provided at the bottom of the square frame 1b.

One scanner is provided on the front side of the square frame 1b.

This desk is installed horizontally on the front part of the square frame 1b,
It is composed of a vertically moving beam 20 that moves back and forth in the vertical direction along the writing surface of the writing medium 2, and a left-right moving body 21 that is attached to this vertical moving beam 2o and moves back and forth in the left and right direction along the writing surface. has been done.

Further, the left and right moving body 21 is provided with 59 holding recesses 24 for removably holding felt bevel 22a, 22b for writing on a writing surface or a cleaner 23 for erasing. The above ben 2 held in
2a, 22tl) or a driving device (not shown) for vertically moving the nona 23 toward and away from the writing surface. The holding recess 24, the driving device, and the felt bends 22a and 22b constitute a writing device, and the holding recess 24, the driving device, and the cleaner 23 constitute an erasing device.

On the other hand, as shown in FIGS. 3 and 4, input devices 25a and 25b separate from the writing medium (*2) are provided.One input device 25a inputs information such as handwritten characters and figures using a writing instrument. The screen has an aspect ratio that matches the writing surface of the writing medium 2.The other input device 25b inputs characters, symbols, etc. using a Bentouch or other means. Alternatively, it is a tablet type character/symbol input device for inputting instruction information such as a print instruction, an erase instruction, a reading instruction, etc. These input devices 25a, 25
The information input in step b is input to the control device 26 shown in FIG. Operate as appropriate.

Next, the action will be explained.

First, an initial operation is performed by turning on the power switch, and the pulse motor 5 rotates backward by a predetermined amount, then changes to forward rotation, and stops when the writing medium 2 reaches the initial position.

Here, when an arbitrary felt-tip pen 22a is held in the holding recess 24 of the scanner 19 and written information is inputted using the input devices 25a and 25b, that information is inputted to the control device 26, and based on the inputted information, One scanner is operated, and at the same time, the driving device built in the left and right moving body 21 is operated, and desired writing is performed on the II recording medium by the moving operation of one scanner and the vertical movement of the felt pen 2a.

Next, if you want to print the information written on the writing medium 2, you can give an instruction to that effect using the input device 25b, and the control device 26 inputs the signal to operate the pulse motor 5, reading station 6, and printer 7. let That is, first, when the writing medium 2 is moved by the motor 5 and the starting position to be printed reaches the light beam irradiation position by the optical vaporizer 8, the photoelectric converter (COD) 12 is turned on, and the light from the reading section 6 is turned on. The read signal is transferred to the printer section 7.

Therefore, the printer unit 7 performs a printing operation, and the motor 5 rotates forward one pulse at a time to move the writing medium 2. When the printing operation is completed in this way, the printed paper 16 is cut into predetermined dimensions by the cutter 17.
The paper 16 is discharged to a paper receiver 18. Note that in the printer section 7, the printing operation is completed, and the cutter 17
After the operation, the paper 16 is returned by a predetermined amount to prepare for the next printing operation.

Furthermore, if you want to erase the information written on the writing surface,
Replace the cleaner 23 in the holding recess 24 and remove the input device 2.
When erasing information is input in step 5b, the information is sent to the control device 26.
Based on the input information, the scanner 19 and the driving device in the left and right moving body 21 operate to perform the desired erasing operation.

The W+ JET described above uses the input devices 25a and 25b provided separately from the writing medium (water) to give various instructions, and based on the input information, outputs one scanner, writing device, erasing device, and reading device. 6 and printer 7 are operated appropriately, it is possible to write on the writing surface and give other instructions at a position away from the writing medium 2.
Even in a meeting with a large number of people, each person can immediately write or rewrite his or her own opinion on a writing surface, thereby increasing the efficiency of the meeting. The final draft written on the writing surface can then be immediately printed and distributed to the attending members.

Note that the present invention is not limited to the above embodiments.

For example, scanners, input devices, writing devices, reading devices,
The erasing device, printer, etc. can be selected from various existing devices as appropriate, and the reading device can be separate from the writing medium.

〔Effect of the invention〕

As mentioned above, according to the electronic blackboard of the present invention, it is possible to write on the writing surface and give other instructions at a location away from the writing medium, and each person at a meeting, etc. Immediately write your opinion on the writing surface.

Alternatively, it can be rewritten and the efficiency of meetings, etc. can be promoted.
