An electronic blackboard device has been developed which has a function of writing with a predetermined writing tool and displaying it to attendees, and reducing the number of these images written on this writing medium on a recording sheet of a predetermined size on the spot. .

For example, Japanese Patent Application No. 58-4428 already filed by the applicant.
No. 3 and so on.

[Problems to be Solved by the Invention] This electronic blackboard device has an extremely effective function of being able to record an image written on a writing medium as described above on a recording sheet in a required number of copies on the spot. At present, it cannot be said that its function is fully exerted, and therefore one of the problems in the future is to enable more versatile use.

The present invention has been made in view of the above problems, and an object thereof is to further diversify the use of the electronic blackboard device.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an electronic device including a large-sized writing medium capable of moving a screen by rotation of a roller, and a recording unit for recording an image written by a writing instrument on the writing medium on a recording paper. In the blackboard device, the writing medium is an endless base sheet formed of a light-impermeable material, a transparent sheet formed of a material in which writing and erasing of an image by the writing instrument are easy, and a transparent sheet of the transparent sheet. At least a side parallel to the roller is attached to the base sheet substantially flatly, and the attach / detach means is deformable along the roller and is moved by the roller together with the endless base sheet. It is characterized by having flexibility.

[Action]

According to the above-mentioned means, not only can an image be written on a recording sheet by writing an image on a base sheet or a transparent sheet that constitutes a writing medium and the image can be recorded on a recording paper, but also a large-sized original document on which the image is handwritten or printed in advance. By sandwiching between the sheet and the transparent sheet, it becomes possible to reduce and record the image of this original on the recording paper. Furthermore, by sandwiching the original such as a map between the base sheet and the transparent sheet, the transparent sheet It is also possible to record an image on the recording paper after adding an image to the document.

〔Example〕

 Embodiments will be described below with reference to the drawings.

1 (A) and 1 (B) are perspective views showing an embodiment of the electronic blackboard device according to the present invention, and FIG. 2 is a partially enlarged side view of the writing medium in FIG.

In the figure, 1 is a large writing medium, which is composed of an endless base sheet 2 and a rectangular transparent sheet 3.

As shown in FIG. 2, this base sheet 2 is formed by bonding a surface film 2b on a milky white, light-impermeable base film 2a, and a transparent sheet 3 is formed on a transparent base film 3a. It is formed by joining 3b. Here, the base film 2a of the mother sheet 2
A whitened polyester film or the like can be used as the base film 3a of the transparent sheet 3, and a transparent polyester film can be used as the base film 3a of the transparent sheet 3, and the surface films 2b and 3b can be easily written with a writing instrument such as a felt pen and erased with a cloth or the like. It is desirable to use a transparent fluorine film.

In the present embodiment, the base sheet 2 is wound around a drive roller and a support roller 5 which are arranged in parallel at a certain distance and stretched. When the drive roller 4 is rotated by a motor 6, the base sheet 2 follows the rotation. It moves circularly.

The reason why the mother sheet 2 is made endless is as follows.

That is, since the rollers 4 and 5 have a cylindrical shape, the lengths of the base sheet 2 and the transparent sheet 3 wound around the rollers 4 and 5 are different. Therefore, if the base sheet 2 is made endless, this difference becomes small and the transparent sheet 3 becomes more difficult to wrinkle. If both ends of the base sheet 2 are rollers 4,
In the case where the roller is fixed to 5 and is rolled out from one of the rollers 4 and 5 and simultaneously wound up by the other roller, 2πΔt (t is the base sheet 2 and the transparent sheet 3 for each revolution of the roller 4 or 5).
(Difference in the distance from the center of the sheet) causes a wrinkle on the mother sheet 2.

On the other hand, by making the mother sheet 2 endless,
The above difference is only for the half circumference of the roller 4 or 5, and the influence is greatly reduced.

Further, when the transparent sheet 3 is rolled in, it becomes thicker than in the case where only the base sheet 2 is used. Therefore, a device casing (not shown) for accommodating and supporting the rollers 4, 5 and the motor 6 and the roller are provided.
Since it is necessary to increase the distance between the sheets 4 and 4, the apparatus becomes large in size, and a larger apparatus housing is required in consideration of a margin for sandwiching a document or the like between the sheets 2 and 3.

On the other hand, if the base sheet 2 is made endless, the transparent sheet 3 or the originals only wrap around to the rear side, so that the device housing can be small and the winding torque may be constant, so that the drive roller 4 is rotated. The control of the motor 6 is simplified.

The transparent sheet 3 is dimensioned to have a size corresponding to one screen of a writing medium, and is detachably provided on each of the two plane portions of the base sheet 2 between the rollers 4 and 5. That is, the transparent sheet 3 can be freely attached to and detached from the base sheet 2, and an adhesive or a magic fastener or the like is used as a means for this.

Therefore, in the writing medium 1 of the present embodiment, two screens a and b are formed by the base sheet 2 and the transparent sheet 3, and the motor 6
Thus, by rotating the drive roller 4 and moving the writing medium 1, the screens a and b can be exchanged so as to be exposed on the front surface of the apparatus.

Reference numeral 7 is a fluorescent lamp as a light source, 8 is a light beam, 9 is a lens, 10 is a reading sensor, 11 is a recording device equipped with a thermal head and the like, 12 is recording paper, and these are Japanese Patent Application No. 58-44283.
It is equivalent to the issue.

Reference numeral 13 is a manuscript in which an image is written in advance, which is a handwritten document, a printed matter, or the like.

Next, the operation will be described. First, when writing an image on the writing medium 1 and recording the image on the recording paper 12, the transparent sheet 3 is removed from the mother sheet 2, and in this state, a writing instrument such as a felt pen is used. Write images such as letters, numbers, symbols and figures.

Then, after the writing is completed, the writing medium 1, that is, the base sheet 2 is moved by the motor 6 in the direction of the fluorescent lamp 7 by rotating the drive roller 4, and the light illuminated by the fluorescent lamp 7 becomes a light beam 8. Read sensor through lens 9
The image is read by means of a projection onto 10.

The read image is recorded on the recording paper 12 by the recording device 11, and the recording paper 12 is ejected outside the device.

This action is the same as that of a normal electronic blackboard device, but the present invention has the following notable actions.

That is, as shown in FIG. 1 (B), the upper side of the transparent sheet 3 is brought into close contact with the base sheet 2 of the writing medium 1 by the attaching / detaching means such as the adhesive or the magic fastener, so that the base sheet 2 and the transparent sheet 3 are separated from each other. After inserting the manuscript 13 between them,
As shown in FIG. 1 (A), the lower side of the transparent sheet 3 or the lower side and both left and right sides are brought into close contact with the base sheet 2 by the attaching / detaching means.

In this state, the content handwritten or printed on the original 13 in advance can be read and recorded on the recording paper 12 in the same manner as described above. Therefore, even when the manuscript 13 is a large map, a design drawing, or the like, it can be easily reduced and recorded.

Further, as the manuscript 13, the map or the staff, or a schedule printed with only the date, is sandwiched between the base sheet 2 and the transparent sheet 3, and the map or the staff is placed on the transparent sheet 3. Alternatively, it is also possible to add symbols, notes, schedule items, etc. to the itinerary, etc., and record this on the recording paper 12 as one image. In this case, since it is not added directly to the manuscript 13,
The manuscript 13 can be used any number of times.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made.

For example, in the above-mentioned embodiment, the mother sheet 2 is capable of writing and erasing an image, but the transparent sheet 3 may be simply attached. That is, the base sheet 2 is made of only the base film 2a such as whitened polyester, and the transparent sheet 3 is always attached to the base film 2a through the attaching / detaching means, and an image is written on the transparent sheet 3 during normal use. , The transparent sheet 3 can be erased or erased to use the base film 2a when the original is used.
The same effect can be obtained by inserting the document 13 between and. Therefore, only the transparent sheet 3 has the function of writing and erasing the image.

Further, the writing medium 1 is moved in the vertical direction in the drawing, but may be moved in the horizontal direction.

Further, in the above-described embodiment, the image is read by the reading sensor 10 and the recording is performed on the recording paper 12 by the recording device 11 having the thermal head. However, instead of such recording means, electrophotographic recording is performed. It is also possible to use means.

〔The invention's effect〕

As described above, the present invention is a base sheet formed by endlessly forming a large writing medium with a light-impermeable material, a transparent sheet formed by a material that is easy to write and erase images with a writing instrument, At least the side of the transparent sheet parallel to the roller is attached and detached so as to be substantially flatly adhered to the base sheet, and various originals can be sandwiched between the base sheet and the transparent sheet. Since the attaching / detaching means is deformable along the roller and has the flexibility to be moved by the roller together with the endless base sheet, the attaching / detaching means can be used as an ordinary electronic blackboard device and also has a large size. After making reduced recordings of maps and design drawings, and inserting manuscripts such as maps and staffs between the matrix sheet and the transparent sheet, and adding to these manuscripts from the transparent sheet This makes it possible to record on a recording sheet as a single image, there is an effect that can be more diversified use of the interactive white board device.

Further, since the base sheet is formed in an endless shape, wrinkles on the base sheet can be prevented even when a transparent sheet is attached, and the winding diameter of the roller does not increase, so that the device can be downsized. In addition, the transparent sheet can be removed from the base sheet when directly writing an image on the base sheet, so that the transparent sheet does not get in the way.
