Description

The present invention relates to an electronic blackboard device in which an auxiliary sheet can be placed on a writing sheet of the electronic blackboard device.

The electronic blackboard device writes characters and figures with a marker on a white writing sheet, and reads the written writing surface as image information by an optical sensor, reduces the read image information, prints it on paper, or It has a function of recording.

The electronic blackboard device is originally written by a user with a marker, and it is difficult to draw an accurate straight line or a circular shape.
However, as a template, a grid-like line, a straight line, a circle, a minutes format, or an image having a shape showing a sports competition area is desired. Japanese Patent Laid-Open No. 8-152859 discloses an information bulletin sheet that is magnetically attracted to a whiteboard or the like.
This information presentation sheet can be printed by a printer.
Moreover, although it is not a patent document, the adsorption sheet which can adsorb | suck without paste conventionally by providing a fine opening in the surface of resin is known.

Since the above Patent Document 1 is magnetically attracted to the surface of a ferromagnetic object, it cannot be used for an electronic blackboard device that does not have a magnetic object surface.
Also, when the writing sheet is transferred and used on an electronic blackboard device that reads the written image on the back side of the main body, it is difficult to print on the electronic blackboard device because the adsorbing sheet is peeled off when wrapping around the back side of the main body. It was.

The conventional suction sheet can be attached and detached without glue, but it is troublesome to store the peeled suction sheet, and it must be left attached.
In addition, for example, when used in an electronic blackboard device having a multi-faced writing sheet or an electronic blackboard device that transfers a writing sheet and reads a written image on the back side of the main body, the suction sheet peels off due to wrinkles when wrapping around the back side of the main body There was a problem of causing it.
This is due to the fact that the radius when the auxiliary sheet wraps around the back surface becomes larger than the writing sheet.
Due to the difference in the wraparound radius, the amount of movement of the auxiliary sheet becomes larger, and when the amount of movement becomes larger than a predetermined amount, the auxiliary sheet is peeled off from the writing sheet and then adsorbed. This is because the operation continues.

In order to solve the above-mentioned problems, the present invention is characterized in that an auxiliary sheet storage portion is provided on a writing board of an electronic blackboard or a support board disposed on the back of the writing sheet.

In addition, the electronic blackboard device has an auxiliary sheet image storage device, and can synthesize and store or print the auxiliary sheet image and the image written on the writing sheet.

According to the present invention, an auxiliary sheet serving as a template and a writing sheet can be displayed in an overlapping manner without using an adhesive, and an image of the auxiliary sheet and an image written on the writing sheet can be combined. It becomes possible to print.
Further, when the auxiliary sheet is not used, it can be quickly stored in the electronic blackboard device.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a front view showing an embodiment of the present invention.
1 is an electronic blackboard body, 2 is a transparent writing sheet for writing on the surface of the main body with a marker, 3 is an instruction to move the writing, and an instruction to search the writing surface of the writing sheet and read writing image information, Alternatively, an operation panel for giving an instruction to print the read data with a printer (not shown), 4 is an auxiliary sheet used as a template, for example, and 5 is a sheet storage unit for storing the auxiliary sheet.
Note that a white support board is disposed behind the writing sheet 2, and this support board has a flat surface without unevenness because it receives the writing pressure by the marker.

A side sectional view of the apparatus of this embodiment is shown in FIG.
The sheet storage unit 5 is configured by disposing a transparent plate 6 with a gap for storing auxiliary sheets on the surface of the support board 7.
Reference numeral 8 denotes a frame of the electronic blackboard body, and a tray on which markers and erasers are arranged is provided below the frame 8.
In the sheet storage unit 5, as a template, for example, a grid line drawn or a predetermined format is used. Theme of meeting minutes, 2. Location, 3. Date and time, 4. Several types of auxiliary seats 4 on which participants and the like are described, a map, a blueprint, a sports ground layout, and the like are stored.

The above-described template image is drawn on the front surface of the auxiliary sheet 4, and the back surface is arranged in the same color (white) as the support board, and this back is stored in the sheet storage unit so as to face the writing sheet surface. ing.
Further, a tag portion is provided at the upper part of the auxiliary sheet 4, and the name of the template, for example, a horizontal line, minutes, map, layout drawing, etc. is described on the tag.
The user selects the required auxiliary sheet 4 from the sheet storage unit 5 and turns it over so as to display the surface on which the image is drawn.

The template image described in the auxiliary sheet is also recorded in a storage device (not shown), and when reading the writing surface of the writing sheet, the template image is read from the storage device and combined with the writing image for recording, or Printed.

The surface of the auxiliary sheet 4 can be written with a marker (not shown), and can be printed with a general printer.
Therefore, the user of the electronic blackboard can use a template image drawn by using a personal computer, for example, by printing it on an auxiliary sheet on which nothing is drawn with a printer.

In this embodiment, when the user creates a template image in this way, the template image must be recorded in the previous recording device. The template image is recorded by connecting a personal computer to the electronic blackboard device and operating the personal computer.

FIG. 3 shows a second embodiment in which the auxiliary sheet storage portion is provided on the writing sheet.
The writing sheet in this case is composed of a conventional white sheet and a transparent cover sheet.
