Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic blackboard device having a large writing sheet i that allows pages to be updated by key operations, and particularly relates to the movement of the writing sheet.

[Conventional technology]

As a conventional electronic whiteboard device, for example, Japanese Patent Application No. 58-857
No. 74 etc. have been proposed, and a schematic diagram thereof is shown in Fig. 2.

In the figure, reference numeral 1 denotes a writing sheet made of a sheet material that can be written on both sides with a writing instrument such as a water-based felt pen, and that can be easily erased to the size of several pages. They are connected to shafts respectively connected to pulse motors 3 for use with the printer, and a length corresponding to one page is stretched between the two shafts, and the other portions are wound around the shafts.

Although not shown here, the writing sheet 1 has page marks detected by a sensor at the boundaries of each page.

4 is a main control unit, 5 is a key power unit, 6 is a display output unit, 7 is a seat drive unit to which both the pulse motors 2 and 3 are connected, 8
9 is a reading means for optically reading both peaks written on the writing medium; 9 is a storage means for storing image information from the reading means; This is a printing means that prints in reduced size on paper.

An electronic whiteboard device with such a configuration is used for meetings, etc.
In a conference room, etc., write on writing sheet 1.
A desired image using symbols 2, figures, etc. is written, and the written image is displayed to the attendees.

If you want to write the entire image on a new page, operate the keys on the keypad section 5 to select another page, and the main control section 4 will output a sheet feed or return signal to the sheet drive section 7.
The operation of the sheet drive unit 7 based on this causes the forward rotation pulse motor 2 or the rewind pulse motor 3 to rotate and wind up the writing sheet 1 around the shaft, so that the writing sheet 1 is sent to the right or left. . At this time, the sheet driving section 7 determines the page mark detected by a sensor (not shown), and sends that information back to the main control section 4, thereby positioning the selected page between the axes of the pulse motors 2 and 3. .

On the other hand, when printing and copying the image written on the writing sheet 1, when the copy key of the key manual section 5 is fully pressed, the main control section sends a message to the sort drive section 7. Reading means 8, storage means 9. Signals for a sheet feed instruction, a reading instruction, and a print instruction are output to the printing means 1o, respectively. At this time, when the number of sheets to be printed is designated by operating the keys on the key input section 5, the designated number of sheets is displayed on the display output section 6.

When the sheet drive unit 7 receives a signal from the main control unit 4, it fully rotates the forward rotation pulse motor 2, and as a result, the writing sheet 2 is wound around the shaft and sheet feeding is performed in the same manner as described above. When the writing sheet 2 is wound up on the shaft, the image of one page written on the writing sheet 2 is read by the reading means 8,
converted into an electrical signal. This electrical signal is sent as image information to the storage means 9 and stored therein, and is further transferred to the printing means 10, whereby the image is printed in a reduced size on a sheet of predetermined size by the printing means 1o.

When a plurality of sheets are to be printed, the main control section 4 outputs the image information for the specified number of sheets from the storage means 9 to the printing means 10, and the printing means 10 performs printing based on the output.

Although the conventional electronic whiteboard device has been described above, this device has the following problems.

[Problem that the invention seeks to solve]

That is, in the electronic whiteboard device described above, the components are housed in the housing so that one page of the writing sheet is exposed on the surface of the device, and is held at a constant height by legs provided in the housing. For example, when writing the entire image near the center of the page, the scribe can write in a comfortable posture, but when writing the entire image at the top or bottom of the page, the scribe must stretch or bend at the waist. However, there is a problem in that writing must be performed in an unstable posture.

In addition to the device that feeds the writing sheet horizontally as shown in Figure 2, there is also a device that feeds the writing sheet vertically, but since the value writing sheet is fed page by page, the @ It is occurring.

The present invention has been made in order to solve such problems, and its purpose is to realize an electronic blackboard device that allows a scribe to easily write an entire image on the entire page of a writing sheet in a stable posture. It is something to do.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention uses a writing sheet that is driven by a motor to move vertically, that is, to feed and return the writing sheet, and also to control the pressing time or time of a key that instructs the movement of the writing sheet. Means is provided for detecting the type and driving the motor for a certain period of time, and by means of this means, in addition to moving one page, the writing sheet can be moved by a certain certain amount less than one page by pressing a key once. It is something.

[Effect]

According to the above-mentioned means, the scribe sets all the writing positions of the image on the basket writing sheet to the position where he or she is most comfortable with writing, writes the image at that position, and after writing, presses the keys for writing. By repeating the action of feeding the sheet by a certain amount in the vertical direction, an image can be written on the entire page without stretching or bending down.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the electronic whiteboard device according to the present invention, and the diagram shows an 11Vi whistle sheet. This writing sheet 11 is formed in an endless shape from the same material as the writing sheet 1 shown in FIG. 2, and here has the size of two pages. given n
ing. This page mark 12 only needs to be detected by a sensor, and may be linear, for example, as shown.

Reference numerals 13 and 14 denote shafts, which are arranged vertically in parallel, and the writing sheet 11 is wound around and stretched around the shafts 13 and 14. Note that the distance between the axes 13 and 14 is set to correspond to one page of the writing sheet 11.

Reference numeral 15 denotes a pulse motor that can rotate in both forward and reverse directions, and is connected to a sheet driving section 20, which will be described later. The seat 11 moves in the vertical direction indicated by the arrow ayb.

17 is a main control section, 18 is a key manual section, 19 is a display output section, 20 is a sheet drive section, 21 is a reading means, 22 is a storage means, and 23 is a printing means, which correspond to 4 to 1 in FIG.
The main control unit 17 of this embodiment has the following functions added.

In other words, the main control section 17 includes a feed key (not shown) for moving the writing sheet provided in the key manual section 18;
A counter 24 is provided to count the time during which a return key (also not shown) is pressed, and the forward key or return key is pressed for a relatively long time, such as 0.5 seconds or more (hereinafter referred to as long press). , the writing sheet 11 moves one page in the direction of arrow a or b, and when the key is pressed for a short time of less than 0.5 seconds (hereinafter referred to as short press), the writing sheet 11 moves in the direction of arrow a or b. For example, a fixed amount of 4. The pulse motor 15 is controlled to be driven via the sheet drive unit 20 so as to move by one page. In addition to the forward key and return key described above, the key manual unit 18 is provided with a copy key for instructing printing and copying, keys for specifying the number of copies to be printed, and the like.

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

Figure 3 is a flowchart showing the process from manual keystroke to movement of the writing sheet and completion of printing and copying, Figures 4 and 4 are flowcharts showing the forward and reverse rotation of the pulse motor, and Figure 5 is the page mark search process. It is a flowchart.

First, to explain how to write an image, write from position 4 between axes 13 and 14 to axis 13 as shown in FIG. If the area on page 4 leading to the position is a position where it is easy to write an image on the writing sheet 11, that is, if the scribe can write the entire image in a comfortable posture, this area is set as the writing position. Let it be C.

Therefore, when attempting to write on both peaks in order from the top to the bottom of one page of the writing sheet 11, if the page mark 12 shown in the figure is located on the axis 13 straddle 14 side, then The writing sheet 11 is moved upward or downward as indicated by arrows a+b so that the mark 12 is at the upper end of the writing position.

This movement is performed in the key manual processing shown in FIG. 3 by briefly pressing the forward key or return key of the key manual section as follows. That is, when the page mark 12 is on the axis 13 side, press the forward key briefly, and when the page mark 12 is on the axis 14 side, press the return key briefly, and the main control unit 17 uses the counter 24 to Alternatively, a short press of the return key is detected, and the pulse motor 15 is rotated forward or reverse for a fixed period of time via the sheet driving section 20, so that the writing sheet 11 is rotated by the fixed amount, for example, as shown in FIG. Move by 100% in the direction of arrow a and b. At this time, the main control unit 17 moves the writing sheet 11 and updates a position counter (not shown).

In this way, when the forward key or the return key is pressed briefly, the flow of control shown in bold lines in FIGS. 3 and 4 is performed.

If the page mark 12 does not come to the upper end of the writing position C with one fixed downward movement, the above-described operation is repeated again to position the page mark 12 at the upper end of the writing position C.

After positioning the page mark 12 at the upper end of the writing position C in this manner, write the entire image on the 4th page portion of the writing sheet 11 at this writing position, and then press the feed key briefly to move the writing sheet 11. Send h hundred minutes in the direction of arrow a. As a result, the next position where no image has been written is placed at write position C.

As the page part comes, write the image again, and click
'4 By repeating this several times, the entire image can be written on the entire page.

When the writing of the image for the entire page is completed, the report page on which the image was first written will be rotated to the rear side of the shaft 14 and will no longer be visible.
By returning 11'e/4 pages in the direction of the arrow, one page of images can be displayed on the front of the device.

Also, after writing all the images on the last 6 pages, change this to -variable axis 1
It is also optional to send it to a high position on the 4th side so that it can be clearly seen by attendees at the rear in a conference hall, etc., and then return it.

Furthermore, if you want to write the image on the next page as is, press the feed key briefly to feed the writing sheet 11 a certain amount t) in the same way as above, and then write the image at writing position C. By repeating the operation multiple times, an image can be written on the entire page.

Next, printing and copying of the image written on the writing sheet 11 as described above will be explained. In the key manual processing shown in FIG. 3, when the forward key or return key of the key manual unit 18 is pressed down for a long time, the main control unit 17 detects this long press by the counter 24, and the pulse motor 15 is controlled at a constant speed via the sheet drive unit 20. Rotate time forward or backward. This allows the fourth
The page of the writing sheet 11 shown in the figure is turned back by i, and the page mark 12 is detected by a sensor (not shown). That is, a page mark search process as shown in the flowchart shown in FIG. 5 is performed, and thereby the page written with the image St to be printed and copied is selected. At the same time, a position counter and a page counter (not shown) are cleared in the main control section 17.

After selecting a page in this way, when the copy key of the key manual section 18 is pressed, the main control section 17 sends a message to the sheet drive section 2.
0. Reading means 21. Signals such as sheet feeding instructions, reading instructions, and printing instructions are output to the storage means 22 and the printing means 23, respectively. At this time, as another key process, when a key is pressed to specify the total number of copies to be printed, the specified number of copies is displayed on the display output section 19.

Now, when the sheet driving section 20 receives a signal from the main control section 17, it rotates the pulse motor 15 in the normal direction, thereby feeding the writing sheet 11. At the same time, the reading section 21 reads the selected signal from the reading section 21. The images written on the page are sequentially read and converted into electrical signals. This electric signal is sent to the storage means 22 as image information, and is stored in the storage means 22, and is also transferred to the printing means 23, whereby the image is printed in a reduced size on a paper of a predetermined size. be done.

When the number of copies to be printed is a plurality, the main control section 17 outputs image information for the designated number of copies from the storage means 22, and the printing means 23 prints copies based on the output.

In the embodiment described above, the endless writing sheet 11 is supported by the shafts 13 and 14 so as to move in the vertical direction, but the writing sheet 1 in FIG. It is also possible to use it by arranging it in the same direction.

Further, in the above-described embodiment, the writing sheet 11 is forwarded or returned by a certain amount and the page is forwarded or returned by a specified amount depending on the pressing time of the forward key or the backward key, but separate keys are provided for each. You may also make a specification. In other words, four types of keys may be provided: a fixed amount forward key, a fixed amount return key, a page forward key, a nine page return key, and the writing sheet 11 may be moved using these keys.

Furthermore, in the embodiment described above, when the forward key or the return key is pressed briefly, the - constant feed amount of the writing sheet 11 is set to /4.
Although the number of pages is limited to nine pages, it is not limited to nine pages. For example, it is appropriate that the writing sheet 11 be fed within about 5 m pages, but if it is a certain amount less than 1 page, it will at least be possible to feed the writing sheet 11, which is the main objective of the present invention. (
*'x It is possible to realize a configuration in which the part to be written can be moved to a position where the scribe can easily write.

In this Ikemizu invention, it is possible to count the amount of movement of the writing sheet 11 from the home position corresponding to the page mark 12, and print and copy the entire selected page by one page from the beginning, as described below. Printing and copying processing such as this is also possible.

That is, when the current state of the writing sheet 11 on the surface of the device is, for example, in a state where it straddles both pages as shown in FIG. It is possible to select three types: a part that spans pages, and a page immediately after ■.

In this case, the key manual processing is to press and hold the return key once, or press and hold the forward key multiple times to move the writing sheet 11, and then the page mark search displays the entire surface of the previous page on the entire surface of the device. If the copy key is then fully pressed, the image on page 2 can be printed and copied, and simply by pressing the copy key, it is possible to print and copy the portion of the image that spans both pages 2. Then, press and hold the feed key once to feed writing sheet 11! When ll is executed, the entire surface of the next page is displayed on the surface of the device by page mark search, so if the copy key is then fully pressed, the image (#!) of the page (■) can be fully printed and copied.

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

That is, as shown in FIG. 7, a mode switching key 25 is used to switch the mode of the previous page, the part that extends up to the page), and the subsequent page.
Display lamps 26 to 28 are provided in the key control unit 18 to light correspondingly, and when the mode switching key 25 is pressed when the copy key is pressed, the selected previous page, current page, or next page is displayed. 15- By allowing images to be printed and copied, three types of printing and copying can be achieved with simple key operations.

Furthermore, the present invention can be applied not only to electronic whiteboard devices, but also to writing sheets and the like. All 1. A shaft/motor that supports it so that it can move in any direction.

From a forward key, a return key, and a control means that drives the motor to move a writing sheet by pressing these keys, a certain blackboard device, a blackboard device that does not have a single image reading means or a printing means. is also applicable.

〔Effect of the invention〕

As explained above, the present invention uses a writing sheet whose tabs are moved up and down in the vertical direction by the rotation of a motor, and which moves the writing sheet forward and back. Alternatively, means is provided for detecting all types and rotating the motor for a certain period of time, and by this means, in addition to page movement, by pressing a key once, the entire writing sheet can be moved by a certain certain amount less than one page. This means that the scribe can move the entire image to a position at a height that makes it easy to write without bending his or her waist or stretching his back. This has the effect that an image can be written on the entire page of the writing sheet. Another advantage is that you can write on the entire page while sitting on a chair.

In addition, since the writing sheet can be moved by a certain amount, if the written images are sent upward one after another, even people at the back of the conference hall can easily view the images without being bothered by the head of the person in front of them. Effects such as being able to see the image can also be obtained.
