BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard for printing an image written on a writing sheet on paper.

[0002]

2. Description of the Related Art Some electronic blackboards include a frame having an opening for exposing a part of a writing sheet. In such an electronic blackboard, an image is written on the writing sheet exposed from the opening. After that, when the copy start key is pressed, the writing sheet is fed and the image on the writing sheet is read by the image reading unit. Then, an image is printed on the sheet based on the read data, and the sheet is ejected.

[0003]

The electronic blackboard described above is used in conferences and lectures. When used in meetings, minutes are recorded, and tables and graphs are added to supplement the presentation. When used at a lecture, a table or graph for supplementing the lecture contents is written. At this time, if a standard format is used, minutes, tables or graphs can be easily written on the writing sheet. As a method of using the standard format, there are a method of printing the format on a writing sheet and a method of sticking a transparent sheet on which the format is printed on the writing surface.

However, when a standard format is printed on a writing sheet, the format is read by the image reading section and printed on a sheet. Therefore, the image written in the portion where the format is printed is limited to the image written according to the format. As a result, the usable range of the electronic blackboard is limited by the format.

Further, when a transparent film on which a standard format is printed is attached to a writing sheet, it is difficult to bring the writing sheet and the film into close contact with each other, and there is a gap between the writing sheet and the film. Since it opens, there is a marker eraser in the gap. Then
The eraser dust of the marker is read by the image reading unit and printed on the paper, and the image printed on the paper becomes dirty. It is also possible that the position of the film shifts when the writing sheet is fed, and the position of the image on the paper shifts.

According to the first aspect of the present invention,
An electronic blackboard that includes an opening that exposes a part of a writing sheet, conveys the writing sheet to the opening, reads an image written on the writing sheet with an image reading unit, and prints the image on a sheet. When a format formed on the writing sheet by the dropout color of the image reading unit, a memory that stores format data corresponding to the format, and an image written on the writing sheet according to the format data are printed on a sheet And a combining unit that forms image data by superposing the format data and the read data read by the image reading unit. Therefore, since the format is formed by the drop-out color of the image reading unit and the format formed on the writing sheet is not read by the image reading unit, only the image written on the writing sheet is printed regardless of the format. When printing on, the read data read by the image reading unit is used as image data, and an image is printed on a sheet based on this image data. Further, the image is written on the writing sheet according to the format. Then, when the image written on the writing sheet according to the format is printed on the paper, the read data and the format data are overlapped by the synthesizing unit to form image data, and the image is printed on the paper by the printing unit based on the image data. Is printed. As a result, the format and the image written according to the format are printed on the paper.

According to a second aspect of the present invention, in the electronic blackboard according to the first aspect, there is provided a positioning mark formed on the writing sheet and around the opening to determine the position of the format and the opening. Therefore, the positioning mark serves as a guide when determining the position of the format within the opening.

And a printer 4 for printing an image on a sheet based on image data. The writing sheet 1 and the image reading unit 3 are housed in a frame 5. The printer 4 is disposed below the frame 5.

The frame 5 is supported by a pair of stands 6. A pair of rollers (not shown) are arranged at the left and right ends of the frame 5. The writing sheet 1 is stretched over these rollers. A motor (not shown) is connected to one of the rollers. On the front surface of the frame 5,
An opening 7 is formed to expose a part of the writing sheet 1. On the right side (lower right side in FIG. 1) of the opening 7,
The input unit 8 is arranged. Below the opening 7,
A receiving portion 10 on which a writing instrument such as the marker 9 is placed is formed.

Images such as characters and drawings are written on the writing sheet 1 by the markers 9. A format 11 is formed on a part of the writing sheet 1 by printing with a dropout color of the image reading unit 3. This format 11 is a key line 12 for creating a table. What is the dropout color?
The color cannot be read by the image reading unit 3. The color differs depending on the type of the image reading unit 3.

First and second positioning marks 13 and 14 for positioning the format 11 are formed on the writing sheet 1 and the frame 5. The first positioning mark 13 is formed on the writing sheet 1. The second positioning mark 14 is formed on the frame 5 above the opening 7. The first and second positioning marks 13, 14 are formed in a predetermined position within the opening 7 when the positions of the first positioning mark 13 and the second positioning mark 14 are aligned. 11 is formed.

The input section 8 is provided with a writing sheet feed key 15, a copy number setting key 16, a display section 17, a mode switching key 18 and a copy start key 19. The writing sheet feed key 15 feeds the writing sheet 1. Copy number setting key 16
Sets the number of sheets for printing the image. The display unit 17 displays the number of sheets set by the copy number setting key 16. The mode switching key 18 selectively switches between the format copy mode and the normal copy mode. The format copy mode is a mode in which the format 11 and the image written on the writing sheet 1 according to the format 11 are printed on paper. The normal copy mode is a mode in which an image written on the writing sheet 1 is printed on paper regardless of the format 11. The copy start key 19 starts a copy operation for printing an image on paper according to the mode selected by the mode switching key 18.

Next, the electrical configuration will be described with reference to FIG. The main body 2 includes a CPU 2 for controlling the operation of each unit.
0 is provided. The image reading unit 3, the printer 4, and the input unit 8 are connected to the CPU 20. A sheet drive unit 21 that drives a motor connected to one of the rollers is connected to the CPU 20. The CPU 20 includes a memory 22 and a synthesis unit 2
3 is connected. The memory 22 stores, for example, programs related to the operation of each unit and format data corresponding to the format 11. The format data is the same information as the image in the state where the format 11 is arranged at a predetermined position in the opening 7. In the combining unit 23, the image reading unit 3
The read data read by and the format data are superimposed to form image data.

In such a structure, an image is written on the writing sheet 1. When the image written on the writing sheet 1 is printed on the paper regardless of the format 11, the user selects the normal copy mode by the mode switching key 18 and presses the copy start key 19.
Then, the sheet driving unit 21 drives the motor to rotate one roller, the writing sheet 1 is fed, and the image reading unit 3 reads the image on the writing sheet 1 to obtain read data. At this time, since the format 11 is formed by the dropout color of the image reading unit 3 and the format 11 is not read by the image reading unit 3, read data that does not include the data of the format 11 is obtained. Then, the read data is used as image data, and an image is printed on a sheet by the printer 4 based on the image data, and the format 11
Regardless of, the paper on which only the image written on the writing sheet 1 is printed is ejected.

When the user writes an image on the writing sheet 1 according to the format 11, first, the user presses the writing sheet feed key 15 to feed the writing sheet 1. Then, when the position of the first positioning mark 13 and the position of the second positioning mark 14 coincide with each other, the user releases the writing sheet feed key 15 to stop the feeding of the writing sheet 1. As a result, the format 11 is arranged at a predetermined position in the opening 7. Then, a table is created according to this format 11.

Further, when the image written on the writing sheet 1 according to the format 11 is printed on the paper,
The user selects the format copy mode with the mode switching key 18, and presses the copy start key 19. Then, the sheet driving unit 21 drives the motor to rotate one roller, the writing sheet 1 is fed, and the image reading unit 3 reads the image on the writing sheet 1 to obtain read data. Then, the format data is called from the memory 22, and the format data and the read data are superimposed on each other in the combining unit 23 to form image data. An operation of forming the image data by superposing the format data and the read data is executed as a function of the combining unit.

Then, the image is printed on the paper by the printer 4 according to the image data formed in the synthesizing section 23, and the paper on which the format 11 and the image written according to the format 11 are printed is ejected.

As described above, since the format 11 is formed on the writing sheet 1 by the dropout color of the image reading unit 3, the table (image) can be easily created according to the format 11. In addition, since the format 11 is not read by the image reading unit 3, only the image written on the writing sheet 1 can be printed on the paper regardless of the format 11, which limits the range of use. Disappears. Further, the read data read by the image reading unit 3 and the format data in the memory 22 are overlapped by the synthesizing unit 23 to form image data, and the printer 4 prints an image on a sheet based on the image data. Therefore, the table (image) created according to the format 11 is printed on the paper. In addition, the first and second positioning marks 13,
Format 11 in opening 7 with 14 as a guide
By deciding the position of the format 11, the format 11 is arranged at a predetermined position in the opening portion 7. Therefore, when the read data and the format data are superposed by the combining section 23 to form the image data, the image in the read data is formed. It is possible to prevent the position of and the position of the image in the format data from being displaced.

It should be noted that the format 11 formed on the writing sheet 1 is not limited to the key line 12 for creating a table, and for example, for creating the minutes shown in FIG. 3 or a pie chart. It can be a circle to create.

As a method of aligning the position of the image in the read data with the position of the image in the format data, for example, a positioning mark is formed on the writing sheet 1 by a color other than the dropout color, and the image reading unit 3 is used. A method of aligning the position of the image in the read data with the position of the image in the format data according to the read positioning mark may be used.

[0021]

According to the invention described in claim 1, since the format is formed on the writing sheet, the image can be easily written according to the format. When printing an image written on a writing sheet on a sheet regardless of the format, the format is formed by the dropout color of the image reading unit, and the format is not read by the image reading unit. Only the image written on the writing sheet can be printed on the paper regardless of the format, and the range of use is not limited by the format. Further, when the image written on the writing sheet according to the format is printed on the paper, the read data read by the image reading unit and the format data in the memory may be superimposed by the synthesizing unit to form the image data. Since the image can be printed on the sheet based on the image data, the image written according to the format and the format data can be printed on the sheet.

According to the second aspect of the invention, since the format is arranged at a predetermined position in the opening by using the positioning mark as a guide when determining the position of the format in the opening, the read data and the format are set. It is possible to prevent the position of the image in the read data from deviating from the position of the image in the format data when the image data is formed by superimposing the data and the data on each other.
