The movement of the sheet is controlled so that the desired position where the image is to be written is located at the position where the image is easily written.

Therefore, according to this, the writer can write an image on the entire page of the writing sheet at a fixed position, for example, a position where the key can be operated, and moves to the position where the user wants to see the image as in the conventional case. Since there is no need, the workability of writing can be improved and the burden can be reduced.

〔Example〕

 Embodiments will be described below with reference to the drawings.

FIG. 1 is a schematic view showing an embodiment of the electronic blackboard device according to the present invention, in which 11 is a writing sheet. This writing sheet 11 is made of the same material as that of the writing sheet 1 of FIG. 2 and has an endless shape, and has a size of two pages, and a linear line is formed at the boundary between the pages. Page mark 12 is given. The page mark 12 is not limited to the linear shape as long as it can be detected by the sensor, and may have any other shape.

Reference numerals 13 and 14 are shafts, which are arranged in parallel to each other at a predetermined interval, and the writing sheet 11 is wound and stretched around the shafts 13 and 14. The interval between the shafts 13 and 14 is set so as to correspond to one page of the writing sheet 11.

A pulse motor 15 is rotatable in both the forward and reverse directions and is connected to a seat drive unit 20 described later.
Is transmitted to the shaft 13 via the belt 16, the writing sheet 11 moves in the left-right direction indicated by arrows a and b.

Reference numeral 17 is a main control unit, 18 is a key input unit, 19 is a display output unit, 20 is a sheet drive unit, 21 is a reading unit, 22 is a storage unit, and 23 is a printing unit. Although corresponding to the constituent elements, the main control unit 17 of the present embodiment is provided with the following functions and controls the movement of the writing sheet 11.

That is, the main control unit 17 includes a feed key (not shown) for moving the writing sheet provided in the key input unit 18 and a counter 24 for counting the pressing time of the return key (also not shown). When the feed key or the return key is pressed for a relatively long time of 0.5 seconds or more (hereinafter referred to as long press), the writing sheet 11 moves in the direction of arrow a or b for one page, and When the key is pressed for a short time of less than 0.5 seconds (hereinafter referred to as a short press), the writing sheet 11 is pulsed via the seat drive unit 20 so that the writing sheet 11 moves a predetermined amount in the direction of arrow a or b, for example, 1/4 page. The control is performed so as to drive the motor 15. The key input unit 18 is provided with a copy key for instructing print copying, a key for specifying the number of prints, and the like, in addition to the above-described feed key and return key.

Next, the operation of the above configuration will be described.

FIG. 3 is a flow chart showing the processing from key input to movement of the writing sheet 11 and completion of printing and copying, and FIG. 4 is a flow chart showing forward and reverse rotation processing of the pulse motor 15.
FIG. 5 is a flowchart showing page mark search processing.

First, the writing of an image will be described. As shown in FIG. 1, a writing sheet is a 1/4 page area from a half position between shafts 13 and 14 to a half position up to shaft 13. If it is a position where it is easy to write an image to 11, that is, a position where the writer can write an image without moving,
This area is referred to as a writing position C.

Therefore, when trying to write an image sequentially from one end on the left side to the other end on one page of the writing sheet 11, if the illustrated page mark 12 is located on the shaft 13 or 14 side, This page mark 12 is one end of the writing position C, that is, the axis 1
The writing sheet 11 is moved rightward or leftward as indicated by arrows a and b so that it is located at the center between the three and fourteen.

This movement is the key input processing in FIG.
The short press of the forward key or the return key of 18 causes the following.

That is, when the page mark 12 is on the axis 13 side, the feed key is shortly pressed, and when the page mark 12 is on the axis 14 side, the return key is shortly pressed. Alternatively, the short press of the return key is detected, and the pulse motor 15 is normally or reversely rotated for a certain period of time via the sheet driving unit 20, so that the writing sheet 11 is rotated by the predetermined amount, for example, 1 / th, as shown in FIG. Arrows a or b for 4 pages
Move in the direction. At this time, the main control unit 17 updates the position counter (not shown) as the writing sheet 11 moves.

As described above, when the forward key or the return key is pressed for a short time, the flow control shown by the bold line in FIGS. 3 and 4 is performed.

When the page mark 12 does not come to one end of the writing position C by one fixed amount movement, the above-mentioned operation is repeated again to position the page mark 12 at one end of the writing position C.

After positioning the page mark 12 at one end of the writing position C in this way, 1/4 of the writing sheet 11 at this writing position
An image is written in the page portion, and then the feed key is shortly pressed to feed the writing sheet 11 by 1/4 page in the direction of arrow a. As a result, the next 1 / 4-page portion in which the image has not been written comes to the writing position C, so the image is written again, and the image can be written on the entire one page by repeating this several times. .

When the writing of the image of the entire page is completed, the 1/4 page in which the image is first written wraps around the rear side of the shaft 14 and becomes invisible. Therefore, by short-pressing the return key 11 By returning 1/4 page in the direction of arrow b, an image for 1 page can be displayed on the front of the device.

Further, when an image is to be written on the next page as it is, the operation of writing the image at the writing position C after performing a fixed amount of feeding of the writing sheet 11 by shortly pressing the feed key as in the above By repeating a plurality of times, the image can be written on the entire page.

Next, a print copy of the image written on the writing sheet 11 as described above will be described.

In the key input process of FIG. 3, when the feed key or the return key of the key input unit 18 is pressed for a long time, the main control unit 17 detects the long press by the counter 24, and the pulse motor 15 is operated via the seat drive unit 20. Forward or reverse for a certain period of time.
As a result, the writing sheet 11 shown in FIG. 4 is page-fed or returned, and the page mark 12 is detected by a sensor (not shown).

That is, the page mark search process as shown in the flowchart of FIG. 5 is performed, and the page in which the image to be printed and copied is written is selected. At this time, the main controller 17 simultaneously clears the position counter and page counter (not shown).

When the copy key of the key input unit 18 is pressed after selecting the page in this way, the main control unit 17 instructs the sheet drive unit 20, the reading unit 21, the storage unit 22 and the printing unit 23 to feed the sheet and read the reading instruction, respectively. , A signal such as a print instruction is output.
Further, at this time, when the key for designating the number of print copies is pressed as another key process, the designated number is displayed on the display output unit 19.

Now, when the seat drive unit 20 receives a signal from the main control unit 17, it rotates the pulse motor 15 in the normal direction, whereby the writing sheet is
At the same time when the feeding of 11 is performed, the image written on the selected page is sequentially read by the reading means 21 and converted into an electric signal. This electric signal is sent to the storage means 22 as image information, is stored in the storage means 22, and is transferred to the printing means 23 so that the printing means
23, the image is reduced and printed on a sheet of a predetermined size.

When the number of printed copies is plural, the main control unit 17 outputs the image information for the designated number of sheets from the storage unit 22, and the printing unit 23 performs the print copy based on the image information.

In the above-described embodiment, the endless writing sheet 11 is used, and the writing sheet 1 is supported by the shafts 13 and 14 so as to move in the left and right directions. However, the writing sheet 1 in FIG. 2 may also be used. It is possible.

Further, in the above-described embodiment, the constant feed amount of the writing sheet 11 when the feed key or the return key is pressed for a short time is set to 1/4 page, but the present invention is not limited to this. For example, it is suitable that the feeding amount of the writing sheet 11 at this time is within about 5 cm to 1/4 page, but at least a fixed amount less than 1 page is at least the main object of the present invention. It is possible to realize a configuration in which the portion where the image should be written can be moved to a position where the writer can easily write.

In addition, in the present invention, the amount of movement of the writing sheet 11 is set as a page mark.
After counting from the home position corresponding to 12, only one page from the head of the selected page can be printed / copied, or the printing / copying process described below is also possible.

That is, when the state where the writing sheet 11 is exposed on the apparatus surface is in a state where it extends over both pages as shown in FIG. It is possible to select three types, a part that extends over the page and a page immediately after.

In this case, the key input processing is performed by pressing the return key once or pressing the feed key multiple times.
If you move 11 above, the whole page of the previous page can be displayed on the surface of the device by page mark search, so if you press the copy key after that,
The image of the above page can be printed and copied, and by simply pressing the copy key, the image of the portion extending over both pages can be printed and copied. Then, when the writing key 11 is fed by pressing the feed key once, the entire next page is brought out to the surface of the apparatus by the page mark search. Then, if the copy key is pushed, the image of the page is printed. Can be copied.

Furthermore, since the writing sheet 11 described above is endless and has a size of two pages, the three types of printing and copying described above can be more easily performed by adding the following structure.

That is, as shown in FIG. 6, a mode switching key 25 for switching the mode of the previous page, the (the part up to now) and the mode of the subsequent page.
And the corresponding display lamps 26 to 28 that are turned on are provided in the key input unit 18, and when the mode switching key 25 is pressed when the copy key is pressed, the image on the previous page, the image on the previous page, or the image selected on the subsequent page is selected. By making a print copy, three types of print copies can be realized by a simple key operation.

Furthermore, the present invention is not only applied to an electronic blackboard device, but also, for example, a writing sheet, a shaft for supporting the writing sheet so that it can be moved left and right, a feed key, a return key, and these. The present invention can also be applied to a blackboard device including control means for driving the motor to move the writing sheet by pressing a key, that is, a blackboard device having no image reading means or printing means.
