DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen type electronic blackboard device.

[0002]

2. Description of the Related Art FIG. 3 shows a configuration example of a conventional screen-type electronic blackboard device.

In this example, when erasing an image output to the read / write target portion of the screen means 10, the operator erases the image with the erasure pad 30 on hand. When outputting the image again to the read target portion of the erased screen means 10, the image is erased with the erasure pad 30 on hand, and the external image is output to the erased read / write target portion of the screen means 10. Outputs an image with the quick-dry ink 70 on hand.

As described above, in order to erase an image output to the screen means 10 and output an external image, the operator needs to operate the erasure pad 30 and the quick-dry ink 70 held by the operator.

[0005]

In the above-described conventional screen-type electronic blackboard device, there is provided a means for automatically dividing and erasing an image output to the read / write target portion of the screen means, and automatically dividing and outputting the image again. In addition, since it is difficult to divide and delete an image precisely, there is a problem that reproducibility is poor even when the image is divided and output again.

[0006]

According to the present invention, there is provided a screen-type electronic blackboard apparatus comprising: a screen portion comprising a spare portion wound around a roller and a read / write target portion; and an image output to the screen portion. An erasing switch for outputting a signal for individually erasing the half and the lower half, and a length greater than a winding width of the screen means, and an image output to the screen means is divided into upper and lower halves. An erasing pad for erasing, and driving means for bringing the upper and lower divided erasing pads into contact with the screen means in response to an erasing signal output from the erasing switch.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a structural view showing an embodiment of the present invention, FIG. 1 (A) is a front view, and FIG. 1 (B) is a side view.

In this embodiment, a screen means 1 comprises a spare portion wound around a roller and a read / write target portion.
An erasing switch 2 for outputting an erasing signal for erasing an image output to the screen means 1 individually in the upper half and the lower half, and having a length equal to or greater than the winding width of the screen means 1; An erasing pad 3 for erasing the output image into upper and lower halves, and an erasing contact between the upper and lower halving pads 3 on the screen means 1 in response to an erasing signal output from the erasing switch 2. And pad driving means 4.

The image output to the screen means 1 is partially divided and erased by the operator pressing the erase switch 2 instead of dividing and erasing the image with an erase pad in hand. For example, in order to divide and delete the image output to the screen means 1, the operator presses the delete switch 2 and selects the upper side or the lower side. When the erase switch 2 is pressed, either the upper side or the lower side of the erase pad 3 incorporated in the erase pad 3 comes into contact with the read / write target portion of the screen means 1 and further interlocks with the screen means 1. Either the upper half or the lower half of the recorded image is deleted.

In order to stop the erasure of the image output to the screen means 1, the erasure switch 2 is depressed again so that the erasure pad driving means 4 built in the erasure pad 3 rises above the screen means 1. , The erasure stops.

Next, an example in which an image output to the screen means 1 is divided into two upper and lower parts and erased and an image is output again will be described in detail with reference to FIG.

FIG. 2 is a block diagram showing a second embodiment of the present invention. FIG. 2 (A) is a front view and FIG. 2 (B) is a side view.

This embodiment is different from the first embodiment in that a printer head means 5 for ejecting quick-dry ink and a printer head driving means 6 for driving the printer head means 5 are added. Reference numeral 5 is disposed immediately before the erase pad 3.

The printer head means 5 is a printer head drive 6 which is driven when outputting an image to the screen means 1.
The erasing pad driving means 4 incorporated in the erasing pad 3 is driven in conjunction with. For example, in the case where the X mark output on the upper half of the screen means 1 is deleted and the O mark is output, the printer head means 5 and the printer head driving means 6
As a result, the erase pad driving means 4 incorporated in the erase pad 3 is driven in conjunction with the output of the mark O, and the erase pad 3 comes into contact with the screen means 1 to erase the mark X.

According to the present embodiment, it is possible to output an image input from the outside with high precision.

[0017]

As described above, according to the present invention, the screen-type electronic blackboard device is provided with an erasing pad for erasing the screen in two upper and lower parts, whereby the image output to the screen means can be finely divided and erased. Have.
