Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a film stretched within a board frame as a white board, draws images such as characters, figures, and tables with a permanent marker, and copies the images. The present invention relates to a whiteboard with a printer, and particularly to the structure of its film.

In recent years, in order to avoid the trouble of having each person copy letters, figures, tables, etc. indented on a white board onto separate sheets of paper at meetings, educational training institutions, etc., and to avoid the mistakes caused by copying, Whiteboards with printers are available that can directly reduce the size of an image written on the whiteboard.

At this time, there is a strong desire to eliminate the trouble of writing repeatedly used frame sizes, coordinates, etc., ie, format diagrams, on the film each time.

[Conventional technology]

Figure 3 is a perspective view of a conventional whiteboard with a printer;
FIG. 4 is a configuration diagram of a whiteboard with a printer.

In FIGS. 3 and 4, on the front side of the board body 1,
A board frame 2 on which a white film 5 is stretched is mounted inside a bordered frame.

The white film 5 is a milky-white polyester film, for example, and its surface (the front side when stretched) is marked with an oil-based marker (for example, a felt-tip pen with magic ink).
It is coated with fluorine resin or the like so that it can be written and erased.

This white film 5 is rolled up on a roll 6 mounted vertically behind one lateral side of the board frame 2. Further, a winding roll 7 is mounted behind the other side of the board frame 2 so as to face the roll 6. Then, the white film 5 wound around the roll 6 is wound horizontally in the direction of arrow A by the take-up roll 7 driven by a motor (not shown), and the white film 5 is stretched inside the board frame 2 and the characters are printed. .

Images such as drawings and tables are written and displayed.

A film rear board 14 is attached to the board body 1 close to the back surface of the white film 5 so that the white film 5 does not bend when writing or erasing an image on the front surface. Further, the configuration is such that the white film 5 can be rewound onto the roll 6.

When the image is drawn on the entire surface of the screen of the white film 5 exposed on the board frame 2 part, the operation panel 3 provided at the bottom of the board frame 2 is operated. Then, the winding roll 7 is driven to wind up the screen on which three images have been written, and a new blank screen of the white film 5 is exposed within the board frame 2.

Next, the printer function will be explained.

A light source 8 that vertically illuminates the white film 5 is installed behind the winding roll 7, and when winding the white film 5 onto the winding roll 7, it illuminates the drawn screen and displays the image. It is projected onto mirror 9. The optical image projected onto the mirror 9 is then focused by a focusing lens 10 onto a light receiving surface of a semiconductor photoelectric converter 11 (for example, a CCD array, etc.).

The semiconductor photoelectric converter 11 converts this optical image into a width of 10 μm, for example.
It scans and reads m columns, resolves them as black and white dots, converts them into electrical signals, and sends them to the printer 12.

Based on this electrical signal, the printer 12 prints dots on, for example, an A4 sheet of paper 13, and copies the image drawn on the surface of the white film 5 in a reduced size.

The paper 13 on which the image has been copied is configured to be delivered to a paper receiver 4 provided on the front side of the operation panel 3.

In the illustrated example, the white film 5 is wound in the horizontal direction of the board frame 2, but there is also a configuration in which the white film 5 is wound in the vertical direction of the board frame 2.

[Problem that the invention seeks to solve]

However, the above conventional whiteboard with printer
Images are written directly onto the white film. Thus, for example, a framed shape.

Format diagrams such as coordinates must be written on the white film each time, which poses a problem of inefficiency.

Also, since this format diagram is drawn freehand,
The problem is that the images are inaccurate and unsightly.

[Means for solving problems]

In order to solve the above-mentioned problems of the conventional art, the present invention provides a transparent material whose surface is treated so that it can be written on and erased with a marker, a selected format diagram is written on the back side, and which is stretched so that it can be rotated and rolled up. This device includes a film and a white back board that is fixed to the board body in close proximity to the back surface of the transparent film.

[Effect]

According to the above means of the present invention, it is easy to draw different format diagrams for each screen using a ruler or the like on the back side of the transparent film in a flat state before being incorporated into the board body.

This formant diagram can be seen through from the front side of the transparent film because the white back board is attached.

Therefore, it is possible to draw desired characters, two figures, etc. in the format diagram on the front surface of the transparent film using the formant diagram written on the back side, and there is no need to draw a new formant diagram on the front surface.

Further, when copying, this format diagram and the image are recorded on paper in an overlapping manner.

〔Example〕

The present invention will be specifically explained below with reference to illustrated examples. Note that the same reference numerals indicate the same objects throughout the figures.

FIG. 1 is a perspective view of one embodiment of the present invention, and FIG. 2 is a plan view of a copied sheet.

In FIG. 1, the transparent film 20 is, for example, a polyester film, and its surface (outer surface when stretched)
is coated with a fluorine-based resin or the like so that it can be written on and erased with a permanent marker (for example, a felt-tip pen with magic ink).

Similar to the conventional white film 5 (shown in FIGS. 3 and 4), the transparent film 20 consists of a roll 6 mounted vertically behind one side of the board frame, and a roll 6 mounted on the other side. The surface of the writing screen is exposed within the board frame by the roll 7, and the board is stretched so that it can be wound up in the left and right direction and returned to its original position.

In order to prevent the transparent film 20 from bending during writing and erasing, a white back board 1 made of a milky white synthetic resin board is placed close to the back surface of the transparent film 20.
4^ is installed.

On the back side of the transparent film 20, a desired formant diagram is drawn in advance for each screen with accurate dimensions and shapes using a ruler or the like.

Format diagram 21 shown in FIG. Formant diagram 22
is one example, where the format diagram 21 is the frame of the process line, and the format diagram 22 drawn in the lower left corner of the formant diagram 21 is the coordinate axis of the graph.

Such format diagrams 21 and 22 can be clearly seen from the front side because the white back board 14^ is attached to the back side of the transparent film 20. Therefore, on the surface of the transparent film 20, the format diagram 21
Lines, symbols, etc. can be written on the graph using a permanent marker, and a desired graph can be plotted using the format diagram 22 as the coordinate axis.

Note that it is of course possible to write any character, figure, etc. in the blank space where there is no format diagram 21 or 22.

After drawing a desired image on the surface of the transparent film 20, when the transparent film 20 is rolled up, a written copy figure 238 is copied overlappingly on the format copy image 21 as shown in FIG. 2, and a format copy image 22A is created. A sheet I3 is obtained in which the copied graph 258 is written using the coordinate axis and the copied characters 248 including G are also copied.

Next, for example, to write down plans for the next year, the transparent film 20 is rewound to expose the previously drawn screen on the board frame. Then, by erasing images such as the words 1 figure drawn on the surface of the transparent film 200, the format diagrams 21 and 22 can be used as they are.

Of course, it is possible to create a structure in which the transparent film is rolled up in the vertical direction, and this is highly effective when applied to, for example, staff notations used in music classrooms and the like.

〔Effect of the invention〕

As explained above, in the present invention, by drawing a format diagram on the back side of a transparent film in advance, there is no need to draw a formant diagram on the film each time, resulting in high efficiency. It has excellent practical effects, such as accurate and beautiful images and the ability to use format diagrams repeatedly.
