Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention comprises a large writing medium whose screen can be moved by rollers, and a recording means for recording an image written on the writing medium on recording paper. The present invention relates to an electronic whiteboard device.

[Conventional technology]

At meetings, briefing sessions, meetings, etc., matters decided as the meeting progresses, the contents of the meeting, or information such as symbols and figures are written on a large writing medium that can be moved on the screen using a roller, such as a water-based felt-tip pen. An electronic blackboard device has been developed that has the function of writing on a designated writing instrument and displaying it to attendees, and also reducing and recording the necessary number of copies of these images written on this writing medium on recording paper of a designated size on the spot. .

For example, the patent application filed in 1986-4 by the applicant
4283 etc. are such examples.

[Problem that the invention seeks to solve]

This electronic blackboard device has an extremely effective function of being able to record the required number of copies of images written on a writing medium on the spot on recording paper as described above, but at present, this function is not fully demonstrated. Therefore, one of the future issues is to enable more diverse uses.

In view of these problems, the present invention aims to further diversify the uses of electronic whiteboard devices.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an electronic device comprising a large writing medium whose screen can be moved by the rotation of a roller, and a recording means for recording an image written on the writing medium with a writing instrument on a recording paper. In the blackboard device, the writing medium is formed into an endless base sheet made of a light-impermeable material;
The transparent sheet is made of a material on which images can be easily written with a writing instrument and is detachably attached to the base sheet.

[Operation] According to the above-mentioned means, it is possible not only to write an image with a writing instrument on a base sheet or a transparent sheet constituting a writing medium and record the image on recording paper, but also to write a large-sized image on which the image has been handwritten or printed in advance. By sandwiching the original between a base sheet and a transparent sheet, it is possible to reduce and record the image of this manuscript on recording paper, and furthermore, it is possible to sandwich originals such as maps between the base sheet and the transparent sheet. It is also possible to add an image to the document from the transparent sheet and then record it on recording paper.

〔Example] Examples will be described below with reference to the drawings.

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

In the figure, reference numeral 1 denotes 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 onto a milky white, light-opaque base film 2a, and the transparent sheet 3 is formed by bonding a surface film 2b onto a transparent base film 3a. It is formed by joining 3b. Here, a whitened polyester film or the like can be used as the base film 2a of the base sheet 2, a transparent polyester film can be used as the base film 3a of the transparent sheet 3, and a writing instrument such as a felt pen can be used as the surface films 2b and 3b. It is desirable to use a fluorine film that can be easily written on and erased with cloth or the like.

In this embodiment, the base sheet 2 is stretched around a drive roller and a support roller 5 that are arranged parallel to each other at a certain distance, and when the drive roller 4 is rotated by a motor 6, the base sheet 2 is Move in circulation.

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

That is, since the rollers 4 and 5 are cylindrical, the lengths of the base sheet 2 and the transparent sheet 3 wound around the rollers are different. Therefore, if the base sheet 2 is made endless, this difference will be reduced, and the transparent sheet 3 will be less likely to wrinkle.

If both ends of the base sheet 2 are fixed to the rollers 4 and 5,
If a structure is adopted in which both rollers 4 and 5 are fed out from one side and simultaneously wound up by the other, two
A deviation of πΔ1 (1 is the difference in distance from the center of the base sheet 2 and the transparent sheet 3) occurs, and this causes wrinkles in the base sheet 2.

In contrast, by making the base sheet 2 endless,
The above difference is only the semicircle of roller 4 or 5, and the influence is significantly reduced.

Furthermore, when the transparent sheet 3 is rolled up, the roll becomes thicker than when only the base sheet 2 is rolled up, so the distance between the rollers 4 and 5 and the device housing (not shown) that houses and supports the rollers 4.5 and the motor 6, etc. This results in an increase in the size of the apparatus, and a larger apparatus casing is required in order to provide room for holding an original between the sheets 2 and 3.

On the other hand, if the base sheet 2 is endless, the transparent sheet 3 or the original document, etc., simply wraps around to the rear side, so the device housing can be made smaller, and the winding torque can be constant, so the drive roller 4 The motor 6 that rotates the motor 6 can be easily controlled.

The size of the transparent sheet 3 is set to be the size of one screen of a writing medium, and the size of the transparent sheet 3 is set to the size of one screen of a writing medium, and the base sheet 2 is arranged between the rollers 4 and 5.
It is detachably provided on each of the two plane parts.

In other words, the transparent sheet 3 is attached to the base sheet 2,
It is designed so that it can be removed freely, and adhesives, magic fasteners, etc. are used as means for this purpose.

Therefore, in the writing medium 1 of this embodiment, two screens a and b are formed by the base sheet 2 and the transparent sheet 3, and by rotating the drive roller 4 by the motor 6 and moving the writing medium 1, the screen a is , b can be alternated so that they are exposed at the front of the device.

7 is a fluorescent lamp as a light source, 8 is a light beam, 9 is a lens, IO
Reference numeral numeral 11 indicates a reading sensor, numeral 11 a recording device equipped with a thermal radar, etc., and numeral 12 a recording paper.
It is equivalent to that of No. 8-44283.

Reference numeral 13 denotes a document on which an image has been written in advance, such as a handwritten document or a printed document.

Next, to explain the operation, first, when writing an image on the writing medium 1 and recording the image on the recording paper 12, remove the transparent sheet 3 from the base sheet 2, and in this state, use a writing instrument such as a felt-tip pen to record the image on the recording paper 12. Write images of letters, numbers, symbols, figures, etc.

After writing is completed, when the writing medium 1, that is, the base sheet 1-2 is moved in the direction of the fluorescent lamp 7 by rotating the drive roller 4 using a mokro, the light illuminated by the fluorescent lamp 7 becomes a light beam 8. The image is projected onto the reading sensor 10 through the lens 9, thereby reading the image.

The read image is recorded on a recording paper 12 by a recording device 11, and this recording paper 12 is ejected from the apparatus.

This effect is the same as that of a normal electronic whiteboard device, but the present invention has the following noteworthy effects.

That is, as shown in FIG. 1(B), the two sides of the transparent sheet 3 are brought into close contact with the base sheet 2 of the writing medium 1 by using the adhesive or the magic fastener or other attachment/detachment means, and the base sheet 2 and the transparent sheet 3 are attached. After the original 13 is sandwiched between the transparent sheet 3 and the transparent sheet 3, the lower edge of the transparent sheet 3 or the lower edge and both left and right sides are brought into close contact with the base sheet 2 by the attachment/detachment means, as shown in FIG. 1(A).

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

Furthermore, as the manuscript 13, the above-mentioned map, music sheet, or itinerary on which only the date is printed is inserted between the base sheet 2 and the transparent sheet 3, and these maps and music sheets are inserted from above the transparent sheet 1-3. It is also possible to add symbols, notes, schedule items, etc. to paper or a schedule, and record this as a single image on the recording paper 12. In this case, since no direct additions are made to the manuscript 13, the manuscript 13 can be recorded many times. It is also possible to use it.

Note that the present invention is not limited to the embodiments described above, and various modifications are possible.

For example, in the embodiments described above, the base sheet 2 is capable of writing and erasing images, but it may also be one in which the transparent sheet 3 is simply attached. In other words, the base sheet 2 is used as a base film 2a such as whitened polyester, the transparent sheet 3 is always attached to the base film 2a via an attachment/detachment means, and an image is written on the transparent sheet 3 during normal use. A similar effect can be obtained by sandwiching the original 13 between the transparent sheet 3 and the base film 2a when the original is used. Therefore, only the transparent sheet 3 needs to have the function of writing and erasing images.

Further, although the writing medium 1 is moved in the vertical direction in the figure, it can also be moved in the horizontal direction.

Furthermore, in the above-described embodiment, the image is read by the reading sensor 10 and recorded on the recording paper 12 by the recording device 11 equipped with a thermal head, but instead of such recording means, an electrophotographic recording method is used. It is also possible to use means.

〔Effect of the invention 〕

As explained above, the present invention includes a base sheet 0 in which a large writing medium is formed in an endless shape from a light-impermeable material, and a base sheet 1 formed of a material on which images can be easily written on with a writing instrument. It consists of a transparent sheet that can be attached and detached from ~, and various manuscripts can be sandwiched between the two, so it can be used as a regular electronic blackboard device, as well as large maps, design drawings, etc. In addition, by inserting manuscripts such as maps and music sheets between the base sheet and the transparent sheet, and adding notes to these manuscripts from the transparent sheet, the dirt is transferred to the recording paper as a single image. This has the effect that the electronic whiteboard device can be used more diversified.

In addition, since the base sheet is formed into an endless shape, even when a transparent sheet is attached, it is possible to prevent the base sheet from wrinkling, and the winding diameter of the roller does not increase, making the device more compact. In addition, since the transparent sheet can be removed from the base sheet when an image is directly written on the base sheet, there is also the effect that the transparent sheet does not get in the way.
