Abstract

PURPOSE:To translate characters to braille symbols from visual characters by a method wherein characters are inputted from a key board, while the characters are stored into a memory storage while being displayed as visual ones and the characters are outputted as braille symbols from the memory storage. CONSTITUTION:Character symbols (visual characters) inputted from an input equipment 2 are displayed as visual ones to a CRT5 through a CPU1 and a visual character generator 4 for visual ones while being memorized at the memory storage 3 (when there is an error, the error is corrected by using the input equipment 2). When a desirable composition is prepared by repeating said operation, and no error existence is made sure by visual display on the CRT5, printing operation is executed and a character row previously stored into the memory storage 3 is outputted as braille symbols through a embossing generator 6 for braille, predetermined projecting sections are formed onto recording paper by means of a recorder 7 for braille, and a document on which braille is displayed is prepared.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Braille word processor that performs translation into Braille.

Conventionally, the method used to translate general documents into Braille is to create protrusions by extruding a bottle from the back of cardboard.

This method has the disadvantage that it takes time to acquire the necessary skills and requires time and effort to carry out the work.

Also, since the person performing the Braille translation work sees from the back side of the paper, the typeface is the opposite of that of the Braille reader! It has to be memorized, and since cardboard is used, the disadvantage is that the amount of paper needed to translate a book into Braille is enormous. Braille typewriters are also used, but the printing method is similar to the method described above.

This invention eliminates the drawbacks of the conventional methods as described above, and allows even people who do not know Braille to easily perform Braille translation.
The object is to provide a Braille word processor capable of creating Braille texts on plain paper or thin plastic film.

Below, several examples of the present invention will be described with reference to the drawings. 1st

) is the dot signal input to the In this specification, visual reading characters refer to all characters VW that are visually d in contrast to Braille, and include kana characters, kanji, numbers, Roman characters, symbols, etc. However, visual reading characters for which there are no corresponding Braille characters are not directly related to this invention.

The types of Braille required have been determined for a long time, and the dot arrangement (
In this specification, the types of characters are distinguished by dot patterns). One type of Braille corresponds to the eye reading character i of ls@, and a digital code χ can be determined to represent each eye reading character, so this digital code can be used to represent the Braille character corresponding to that eye reading character. Can be done.

Since the eye reading character can also be represented by a dot pattern, the correspondence between the digital code representing the eye reading character and the dot pattern of the eye reading character, for example, in ROM (re
ad-only-memory). Character generator for eye reading characters (4
) stores the correspondence between dot patterns and digital codes for all the reading characters corresponding to all the Braille characters used in this device. The Braille character generator (6) stores correspondences between Braille dot patterns and digital codes for all Braille characters used in this device.

Since the character keys of the input device (2) are displayed in visually readable characters, the device shown in FIG. 1 can be easily operated by an operator with limited knowledge of Braille. C.P.

α9, ueo status is the same as when a CRTY for displaying characters and numbers is attached to an ordinary calculator, so a detailed explanation will be omitted, but when you press the character key on the input device (2), the character number will be displayed. Digital codes are output and stored in an array in a memory device (3) under the control of the CPU (1). At the same time, the CPU (1) uses the memory device (3)
The digital data stored in
It is converted into a video signal by a visual character generator (4) and displayed on a CRT (5). Therefore, the operator of the input device (2) inputs data sequentially while observing the reading characters (displayed by a dot pattern) displayed on the display surface of the CRT (5), and if necessary inputs the characters first. Correct the digital code χ entered into the CRT (
5) Check that it is displayed correctly on the display screen. This means that the arrangement of the desired digital code in the memory device (3) is complete.

Next, C2, the operator operates the function key χ on the input device (2) to instruct the CPU (13) to create a Braille record.

Braille recording is carried out by forming protrusions 7 representing a Braille dot pattern on a mount (not shown in FIG. 1) placed on a Braille recorder (7). Braille recorder (7)
For example, a recording head χ of an X-Y recorder having a suitable structure can be used. Plain paper or a thin plastic film is used as the mount, and coagulable plastic fluid or molded 7+=i particles are ejected onto this to form protrusions χ representing the dot portions of Braille. It is equipped with cypress wood for storage.
It is possible to use a recording gun having a structure in which a predetermined amount of fluid or one particle is ejected each time the recording operation is controlled.

As with the recording head of a conventional X-Y recorder, the position of the recording gun of the Braille recorder (7) is controlled by a signal a8. This control is performed in synchronization with the reading of the memory device (3) by the signal αυ and the control of the Braille character generator (6) by the signal (17)l2. Memory device (3)
Character generator for character reading and visual reading (4) χ
The operation of displaying the dot pattern of reading characters on the CRT (5) is also performed by reading out the memory device (3) and using the Braille character generator (6)'! 'Intermediate braille recorder (7
) is the same operation in principle, but since the scanning speed of the Braille recorder (7) is significantly slower than that of the CRT (5), the signal α
The address change χ at υ1; must be given to the read signal dw to the braille character generator (6) with a significant delay. The signal controlling the recording operation of the recording gun is provided by signal α.

When the operator operates the keys as shown in FIG. 3(b) on the input device (2), the code as shown in FIG. 3(b) is stored in the memory device (3) and the code as shown in FIG. The visual reading characters shown in Figure 3 (at) are displayed.The contents of the memory device (3) are checked using these visual reading characters, and if necessary, the corrected upper Braille recorder (7) starts recording χ. , the CPU (11) controls the position of the recording gun (73), for example, the position in the X-axis direction (Xl) as shown in FIG.
IX1! , The code read from the memory device (3) is input to the Braille character generator (6) and the Braille dot pattern corresponding to this code is read out, but one Braille character has multiple dots in the Y-axis direction as well. Since I have a recording gun (7
3) In the first scan in the X-axis direction, only the first line of the Braille dot pattern is read out, and the positions corresponding to the logic "1" (see Figure 3 (mountains X11, X21, X, , X4)
．． ,X,iX6. , When the scanning of the first line in the X-axis direction is completed, the scanning of the second line starts and the position of the recording gun (73) is displaced by a unit distance in the Y-axis direction. In this case, the memory device (3) reads the first line. The same code as that at the time is output, and the memory of the second line of the dot pattern is output from the Braille character generator (6), resulting in the control signal 4.

In the example shown in FIG. 3, the movement f'? in the X-axis direction by three lines?
When this is done, printing of one line of Braille text is completed and the next line is printed.

A viscous fluid is stored in a tank in the recording gun (73), and a signal from a signal line (74) applies pressure to this viscous fluid at the same time: Open the nozzle χ of the recording gun (73) to release an appropriate amount of fluid. The viscous fluid 7 is discharged onto the mount (70). This viscous fluid may pass through the injection port made of a thin tube, form a droplet, form a solid layer on the surface of the mount (70), and then solidify.Such a viscous fluid may be used, for example, as an adhesive. It can be selected from those commercially available. Also, instead of a viscous fluid; for example, a gun (73) that records particles with a pre-shaped bottom (for example, a hemisphere with a diameter of 1 mtn or less)
It may also be injected from the base plate and fixed on the mount '(70). As the mount (70), in addition to plain paper, synthetic paper, film, metal plate, wooden board, etc. can also be used.

As described above, according to the present invention, it is possible to print error-free Braille text without having to worry about the operator's lines.
