Abstract

PURPOSE:To eliminate the need for continuing pen touch forcedly, and to facilitate an operation by storing the position of an input pen when the input pen is touched and marker-displayed under the set of a marker mode, and continuing its display till the input pen is touched again. CONSTITUTION:When a marker is displayed at a desired position by pen- designation while picture drawing data is being transmitted, and the same marker display as this is displayed at an opposite party side, the marker mode is designated by depressing a marker key 10, and the inputting pen 4 of the picture drawing tablet 1 of a transmission side terminal is put into pen-down at a prescribed designated position, and a marker is displayed on a screen, and simultaneously, the data is sent to the terminal equipment of the opposite party side so as to be marker-displayed on the screen. At that time, even though the input pen 4 is in a pen-up state, i.e., it is kept apart from the surface of a digitizer 2, and marker display is continued as it is at the touch position of last time until the input pen is made to touch the digitizer 2 next time. When an operator wants to marker-display continuously, it is needless to continue the pen touch, and the operation becomes very easy.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a handwritten information input device used in a drawing communication device and the like, and particularly to a handwritten information input device characterized by marker display.

(B) Conventional technology In general, drawing communication devices each have a handwritten information input means for inputting handwritten information as a terminal device, a two-dimensional display for displaying this handwritten information as it is, and a transmitting device for transmitting the input handwritten information to the other party. (each equipped with a transport means,
Information handwritten by each other is displayed on the display of the device itself, and is also transmitted to the other party and displayed on the other party's display. In this type of drawing communication device, in marker mode, which is one of the communication commands, when the sending side is pen down, so-called input pen is touching the tablet, coordinate position data of the pen down position is transmitted from the sending side to the receiving side. Also, on the receiver's display, a marker is displayed at the same position as the transmitter's pen down position to convey the instruction point from the transmitter to the receiver. Traditionally, this type of marker display was only displayed while the pen was down.

(c) Problems to be Solved by the Invention In the handwriting information input device in the conventional drawing communication device described above, in order to continue displaying the marker, even at the same indication point, the pen must always be held down on the tablet. There was a problem in that the user had to keep touching the screen, which made the operation extremely troublesome.

This invention was made by focusing on the above-mentioned problem, and once a marker is displayed by pen down in marker mode, the marker continues to be displayed even if the pen is removed from the tablet and the pen is brought up. The purpose of the present invention is to provide a handwritten information input device that can be used to input handwritten information.

(d) Means and Effects for Solving the Problems The handwritten information input device of the present invention includes an input pen, a pen position input means for capturing position data of the touch position when the input pen is touched, and a handwriting information input device of the present invention. a two-dimensional display for displaying pen position data; a marker mode setting means; a position for storing the position data when the input pen is touched under the marker mode setting and the position data is captured; a storage means; a marker display means for displaying a marker at a corresponding position on the two-dimensional display according to the position data stored in the position storage means; and a marker display means that is set when the input pen is touched and is set at the next touch of the input pen. It is characteristically provided with state storage means which is reset and holds the marker display of the marker display means by the set output thereof.

In this handwritten information input device, a marker is displayed,
When it is desired to give some instructions to the other party, first, the marker mode setting means sets the marker mode, and in this state, the input pen is moved down to a predetermined position. By this pen down, the position data of the touch position is taken in by the pen position input means and recorded in the position storage means.
．． It will be done.

A marker is then displayed at a corresponding position on the two-dimensional display, that is, a marker is displayed at the position touched by the pen. Then, once the input pen is touched, even if the pen is brought up, that is, the pen is removed, the state storage means remains set until the input pen is brought down again. The state storage means continues displaying the marker until the next input pen is pressed down.

(E) Examples Hereinafter, the mini invention will be explained in more detail using examples.

FIG. 2 is a block diagram showing one terminal device (handwritten information input device) of the drawing communication device in which the present invention is implemented.

In the figure, a drawing input tablet 1 includes a transparent digitizer 2 for inputting position information according to the down scan of an input pen 4, a liquid crystal display 3 on which the transparent digitizer 2 is placed, and a transparent digitizer 2. controls the X-axis input port 5, Y-input captro, and pen drive unit 9 for respectively capturing the X-axis coordinate signal and the Y-axis coordinate signal, and also captures input position data from the input port 5.6;
Furthermore, in order to display the captured position information, a CPU is used to input the captured position information to the liquid crystal display 3 through the drive circuit 8.
Furthermore, keys 10, 11, and 12 are used to specify the marker, trace, and erase modes to the CPU 7, and the input data is sent from the CPU 7 to the other party, or conversely, data from the other party is sent through the telephone line 14. The receiver is composed of a communication control section 13 and a receiver.

In this type of terminal device, when transmitting drawing information from all devices to the other party, touch the pen 4 to the digitizer 2 while the telephone line 14 is connected to the other party by telephone call. When the pen 4 is moved by touch on the digitizer 2, the coordinate signals of the moving point are taken in from the X-axis input port 5 and the Y extraction capotro, respectively, and the moving point of the pen 4 is calculated based on the signal level taken in by the CPU 7. Then, the calculated Y-axis and Y-axis position information are displayed correspondingly on the liquid crystal display 3 through the drive circuit 8, and are also transmitted to the other party via the communication control unit 13 and telephone line 14, and displayed on the other party's liquid crystal display B3. It will also be displayed.

If you want to display a marker at a desired position by specifying a pen while transmitting drawing data as described above or transmitting a fax document (not shown), and have the other party display the same marker, Press the marker key 10 to specify the marker mode, as shown in Figure 3.
The input pen 4 of the drawer Kakuplet 1 of the sending terminal device 20 is moved down to a predetermined designated position, and the marker 3a is displayed on the screen, and this display marker data is also sent to the other party's terminal device 30, and the same is done. A marker 3a is displayed on the screen.

In the terminal device of this embodiment, when the marker display 3a is displayed on the screen in the marker mode, even if the input pen 4 is lifted up, that is, separated from the surface of the digitizer 2, the input pen 4 is moved back to the digitizer 2. The marker display 3a continues to be displayed at the same position, that is, at the previous touch position, until it is touched.

Next, the marker display operation in the terminal device of the drawing communication device of the above embodiment will be explained with reference to the flowchart shown in FIG.

When the operation starts, it is first determined whether there is a pen input or whether data has been received from the other party [Step ST (hereinafter abbreviated as ST) 1]. In particular, if there is no pen input and no data is received from the other party, the STI determination is NO, and then it is determined whether or not the marker mode is in effect. In this case, if the marker key 10 is not turned on, the determination of Sr1 is also NO, and normally the operation is waited for here. Now, if the input pen 4 of the own device is operated or the input pen of the other party is operated and data is received, the STI judgment becomes YES and the marking display is stopped, that is, until then the marker mode is , if a marker is displayed, the marker ring display is temporarily stopped here (5T2), and it is determined whether the marker mode is in effect or the marker command has been accepted (Sr1). Normally, when transmitting to the other party,
As shown in FIG. 4, commands indicating marker, trace, erase, etc., and coordinate data that encodes subsequent position information are sent. FIG. 4 shows that at the same time a command is sent each time the pen is down, encoded coordinate data is sent thereafter until the pen is up. Therefore, S
In r1, if the marker mode is in effect or a marker command has been received from the other party, the determination is YES, and in this case, the marker mode is set (Sr1). However, this marker mode set is only for the receiving side. Next, marker display processing is performed using the sent or input coordinate data of the position (Sr.
5) Store the marker display position, that is, the coordinate data as is (Sr1). Then return to STI. here,
By marker display processing, a marker display is continuously lit at the position where the pen is down. This continuous lighting indicates that the pen is still in the down position. Then, the position is stored as is in the storage means.

If the pen-down state continues, the above STI to ST6 will occur.
The processing will continue as is.

Eventually, when pen 4 is pen-up, Sr1
The answer is YES whether it is in marker mode or if a marker command has been received, and the process continues up to Sr1, but when it returns to STI again, the determination as to whether there is pen input becomes No, and Sr1 switches to marker mode. It is determined that it is medium. Note that if the marker mode has not been reset, marker coupling processing is performed this time (STIO). As a result, the marker display 3a lights up blinking. Therefore, depending on whether it is continuous lighting or bling lighting,
The other party looking at the screen can know whether the input pen 4 is down or up.

When the input pen 4 is moved down again while in the marker mode, a new marker display process at that position begins. When the marker mode is not in effect, that is, when the marker mode key 10 is turned off, the determination of Sr1 becomes NO, and in this case, the marker mode is reset.
r7), performs other drawing processing (ST8), and returns to STI.

As described above, in the terminal device of this drawing communication device, when a marker is displayed at a predetermined position with an input pen and the marker display is transmitted to the other party for display, - once an instruction is made with the input pen, a marker is displayed at that position. Since the display is displayed and the position is memorized and the display continues, even after the pen is raised, the instruction can be displayed to the other party until the next pen is lowered.

Furthermore, depending on whether the display is lit continuously or blinks, it is possible to know whether the other party's input pen is currently pen-up or pen-down.

(f) Effects of the Invention According to this invention, when the input pen is touched and a marker is displayed, that position is memorized and the marker continues to be displayed at that position until the input pen is touched again. Therefore, when the operator wants to display marker instructions continuously, there is no need to forcefully continue touching the pen, making the operation much easier. Is displayed.
