Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a handwritten information reproducing method that can read handwritten information written on a brass plate in one direction and in the opposite direction.

(2) Technical background A device that records handwritten characters and figures (hereinafter referred to as external memory)
This is displayed on a display to teach the writing order of letters or to explain the temporal context of graphic shapes (for example, when explaining the order of the arrangement of stones in Go).
Therefore, a reproduction method having a function of reading necessary information from an external memory or erasing unnecessary information becomes necessary.

Conventionally, the error information is read out from an external memory,
This is displayed on the display, and the part to be erased is erased in the forward direction, so it was not possible to display the temporal relationship of the figure ◎ For this reason, in addition to layer direction playback, both reading and erasing of reverse playback A method for reproducing handwritten information with functions is 1! It was desired.

(3) Prior art and study points Figure 1 shows a conventional example of a handwritten information reproduction method using a digitizer. Data is drawn on a digitizer 1-1 with a stylus pen 1-2, and data is input to the input data sample control circuit 2. Adjusted to a predetermined data rate, the output of the conversion circuit 2 passes through a switch 3, is converted into a bust signal by a vector dot converter 4, and is displayed on a display 6 via a receipt memory 5.

-The handwritten information of digitizer 1-1 is stored in external memory 7.
is stored in

Now, the character input is stored in the external memory 7, and the screen address of the character input (*Y5 shown in ZwA) is input from the input device 8.
g-), the required screen data 13-1 (FIG. 2) containing characters is read out from the external memory 7, the decoder 9 detects the screen address, and the switch 3 converts the vector dot. The character A is displayed on the display 6 via the device 4 and the refresh island memory 5.0 With the character input displayed, the output of the character input from the external memory 7 is inverted and inverted by the vector dot converter 4. You can erase the text displayed on the display.

Now, with the character entry displayed on the display 6, the writing order of the character entry will be explained. The writing order of the character input is 10 → 11 → 12 as shown in Figure 2 (a), and the character input vector from the external memory is taken out and inverted, inputted to the vector dot converter 4, and its When the output is input to the refresh island memory 5, the characters entered on the display 6 are erased in the order of 10→11→12.

In this case, if you want to leave the lO at the beginning of the writing of the letter A for the purpose of explaining the writing of characters, there is a drawback that it cannot be displayed by reading in the forward direction. (4) Purpose of the Invention The present invention addresses the above-mentioned conventional drawbacks and provides a novel handwritten information reproduction method that can display the process of screen generation by having functions for both forward and reverse playback of reading from external memory. (5) 11I formation of the invention And according to the present invention, in a handwritten information reproduction method for reading handwritten information of characters and figures from a recording device and displaying it on a display device, the recording device 0(6) Embodiment of the Invention This invention is achieved by reading out and displaying handwritten information in the input order of handwritten characters and figures in the order in which they are input, and reading out the information in the opposite direction and inverting the invention. The invention will be described based on the invention summary diagram of 2008, and the handwritten characters and external memory shown in FIG.

With reference to FIG. 3, the writing order of character entry shown in FIG. 2 (0) will be explained. One screen of data 13 having the leading mark shown in FIG. -1 is connected, and the skeleton data 13 is displayed on the display 6 through the contact 16-1 of the switch 16, the vector dot converter 4, and the data memory 5. In this case, the number of characters is 10
At this time, the starting position of the external memory 7 is w4Y- after the data 13.

Next, data 13 is drawn out in the opposite direction 17 yo this special sale IK
! -ri I is first read out, and then vector ^ is squeezed out from the external memory 7.

When the external memory 7 is started in the opposite direction, the data 13 shown in Figure 2 (middle) is at the beginning! - The data 13 is read out from the external memory 7 in the order of vectors 13-1, and the data 13 passes through the backward direction register 18 and reaches the vector data detector 19 at the top! - When the seal is detected, the contact 16-2 of the switch 16 is connected by the wrinkle detection signal, and the data 13 is transmitted to the contact 16.
-2 and vector dot transformation l! 4 is input. At this time, if the polarity of the data 13 is reversed and inputted to the refresher 4, the character A written above in the refresh memory 5
is erased, and the character entry displayed on the display 6 is erased.

If you slowly perform the above reverse direction 17 narrowing down, you will be able to enter 1 character.
If you want to erase in the order of 2-11-10 and keep only 10 of the person who started writing, you can stop narrowing down the external memory at 10. In addition, the educational effect can be further increased by operating 12 → 11 → 10, or by erasing once and reading it out again in the forward direction 14 to display the writing order. . In the figure, when a reverse playback instruction is input through the information control input device 20, the input g
The output of 120 is input to a dot conversion control section 21, and the output of the control section 21 is input to an instruction control section 22, a vector dot converter 4, an address trace counter (up/down counter) 23, a shift register 24, and an up/down counter 25. The information is read out from the external memory 9 in the forward direction. In this case, the read data is the data 13 shown in Diagram 2 (B). When the target screen's destination I [i-ri I is detected by the decoder 26 for detecting the destination II mark, the address is traced using the nuclear detection data. The gate of the counter 23 is opened, and thereby the T data 13 shown in FIG. The Mukuro output is vector information of MuX, Δy, and SX.

The polarity information of SY is used as an exclusive OR circuit (hereinafter gate T above)
27 and 28 (at this time, the output of the register 29 is at the O level) is input to the address trace counter 231, and its output passes through the vector dot conversion 4 and the refresh memory 5, and then inputs characters to the display 6. Figure 2 (
As shown in b), the numbers are displayed in the order of 10 → 11 → 12. This display continues for one screen until the next leading mark l is detected.

At this time, the last address of the screen is recorded in the address trace counter 23, and transmission and reproduction starts from this address as the starting point.

When the forward playback ends, the next WR margin 1 is detected, the register 29 is set, and the data in the external memory 9 (second
Start reading out Figure (b)) in the reverse direction.

In this case, the shift register 24 outputs vector information of ΔX and ΔY and polarity information of sx and sy. In this case, the polarity information sx, sy is inverted at gates 27 and 28 by setting the register 29 to reverse the vector direction.

These vectors ΔX, ΔY and the reversed polarity sx,
sy is outputted from the vector dot converter 4 via the address trace counter 23, and the input characters displayed on the display 6 via the address trace counter 23 are outputted in the sequence 12-- shown in FIG. 2(a). Erase with 11-10.

(7) Effects of the Invention According to the present invention, a displayed character or figure can be completely erased by reproducing the same memory in reverse, and it is possible to teach the folding order of letters and to correct over-forming in figure formation. It has advantages that can be explained clearly.
