BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent electronic blackboard.

0002

2. Description of the Related Art In conventional electronic blackboards, writing is performed on a sheet, which is a writing section, using an electronic blackboard oil-based pen, and the information is erased using a blackboard eraser, and page breaks are performed by winding up the sheet. To copy the screen, data scanned by an image sensor is printed when the sheet is wound up.

0003

[Problems to be Solved by the Invention] With conventional electronic blackboards, since it is necessary to write on a sheet, it takes time to wind up the sheet during page breaks and copying, and writing cannot be done during that time.

[0004] A sheet with a length corresponding to the number of pages that can be used for page breaks is required.

[0005] Since information is written using an oil-based pen for electronic blackboards, it is necessary to take precautions against stains and eraser marks on the sheet.

[0006] When using a document written on paper, it must be copied, and the lines must be drawn by hand or using a ruler.

An object of the present invention is to provide an intelligent electronic blackboard that can digitize input information and display digitized information.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the intelligent electronic blackboard according to the present invention has the following features:
An intelligent electronic blackboard having a writing section, a control section, and an interface section, the writing section digitizing input information and displaying the digitized information on a screen, and the control section: It has a control function to display the digitized information from the interface section on the screen in the description section and to output the digitized information displayed in the description section to the interface section. , and a general-purpose input/output adapter.
It inputs and outputs electronic information.

Further, the description section has a display section for displaying electronic information on a screen, and an input section for inputting coordinate data to the control section.

[0010] The control unit also has a function of specifying the page of the electronic information displayed in the description part and changing the page, a function of drawing and deleting a line on the screen of the description part, and a function of drawing and deleting a line on the screen of the description part. It has functions such as copying the electronic information displayed on the screen.

[0011]

[Operation] The information input to the description section 1 is digitized, the digitized data is input, and the information is displayed on the screen in the description section 1 under the control of the control section 2. It outputs data.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, the intelligent electronic blackboard according to the present invention has a writing section 1, a control section 2, and an interface section 3.

As shown in FIG. 2, the description section 1 includes an input section 1a.
and a display section 1b. The input section 1a uses a coordinate input device such as a touch screen or a light pen, and the display section 1b uses a display device such as a liquid crystal LED.

The coordinate data obtained from the input section 1a is sent to the display section 1b via the control section 2, and the same coordinates are displayed.

The control unit 2 mainly includes a CPU, a control program, a memory for displaying images for several pages, a writing/erasing switch, and a group of command switches.

The image display memory of the control section 2 is used for page breaks.

The writing/erasing changeover switch of the control section 2 is a switch for the operator to select whether to write or erase when inputting from the description section 1, and the command switch group is used for page break, page specification, etc. This is provided for the operator to issue commands such as , copy, etc.

The control program of the control section 2 includes the description section 1,
It controls the control section 2 and the interface section 3, and particularly has a key line function for writing and an erasing function.

Here, a line and erase function will be described as an embodiment. In this embodiment, the word "mark" is defined as follows. "Mark" means quickly touching the same coordinates twice on the input section 1a. that time,
The shift in coordinates caused by two touches should be considered and adjusted to the extent that it cannot be mistaken for a dakuten.

The key line function is valid in input mode. Things that can be drawn are horizontal lines, vertical lines, and box shapes. The horizontal and vertical lines first mark the starting point, as shown in FIG. 3A(a). Then, as shown in FIG. 3A(b), touch the end point. A horizontal line or a vertical line is determined based on the position of the end point. That is, as shown in FIG. 3A(d), in the relationship between the angle A that the line connecting the starting point and the ending point makes with the horizontal line and the angle B that the line makes with the vertical line, if A≦B, it is determined as a horizontal line, and A> In the case of B, it is determined as a vertical line. Figure 3A(b
), it is determined to be a horizontal line, and a horizontal line is drawn as shown in FIG. 3A(c).

Regarding the box shape, if the starting point and end point are marked on the diagonal line of the box shape as shown in FIGS. 3B(a) and (b), the box shape can be drawn as shown in FIG. 3B(c). In addition, by using the command switch group of the command switch 2 of the control section 2, the key line function can be easily performed by specifying coordinates or the like.

Next, the erase function is enabled in erase mode. There are two methods: a method of erasing the touched area as shown in FIG. 4A, and a method of specifying a range as shown in FIG. 4B.

FIG. 4B(a) shows how to specify the range.
, (b), if you specify the start point and end point, Figure 4B
As shown in (c), the area designated for deletion is displayed in a blank area. As shown in FIG. 4B(c), if the inside of the area is touched after the area is displayed, the inside of the area is erased (see FIG. 4B(d)). Deletion can be canceled by touching outside the area, and this can be easily done using the command switch group of the control unit 2. The interface unit 3 includes a personal computer image input adapter 3a and a general-purpose input/output adapter 3b. By connecting the display cable of the personal computer 4 to the personal computer image input adapter 3a, it can be used as a display for the personal computer 4. Further, peripheral devices such as an image reader and a printer are connected to the general-purpose input/output adapter 3b (FIG. 5).

Therefore, data is digitized and inputted from the input section 1a of the description section 1, and the data is output and displayed on the display section 1a under the control of the control section 2. This allows the data on the personal computer 4 to be displayed on the description section 1 and used or edited. Further, by incorporating or connecting the image reader 5, there is no need to copy the document on the writing section 1.

[0025]

As explained above, since the present invention uses electronic display, page breaks and the like can be processed at high speed, and there are no eraser marks or stains caused by the pen, so maintenance is easy. In addition, by incorporating or connecting an image reader,
It is no longer necessary to copy the document, and there is no need to handwrite the lines. Furthermore, by connecting a personal computer, data from the personal computer can be displayed in the description section for reuse and editing.
