Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 shows a block diagram of a voice recorder with an image scanner function of the present invention.

The voice recorder stores and outputs voice data by operations of the voice input / output unit 2 connected to the central processing unit 1, an output display unit 3 for displaying the driving state of the central processing unit, and the central processing unit 1; And a memory unit (4), which is connected to an external personal computer (20) via a data bus and an interface unit (5) connected to the central processing unit (1), and this structure is a conventional voice. Same as the structure of the recorder.

The present invention includes a key operation unit 6 capable of selecting an operation mode of the central processing unit 1 of such a conventional voice recorder, and an image scanner 7 connected to the central processing unit 1 via a data bus. And a ROM section in which the character and word voice data in the memory section 4 are stored.

First, the present invention adds the function of an image scanner to the function of a conventional voice recorder. The function of a simple voice recorder reproduces and stores voice data according to the switching mode, and the post-scanning voice output as a voice signal after scanning. It has an output function and a download and voice output function for outputting text and voice data received from the personal computer as a voice signal in connection with a personal computer. The voice output function after scanning is data for transmitting voice recorder data to the personal computer. It includes a transfer function.

As a result, the key operation unit 6 operates a simple voice recorder function, the above voice output function after the mode scanning, and the voice output function after the download by a switch.

First, when the key operation section 6 is switched to a simple voice recorder function, this performs the same function as a conventional voice recorder.

That is, at this time, it is operated by a reproduction and recording switch (not shown), and the audio signal input through the voice input / output unit 2 is stored in the memory unit 4 via the data bus. At the time of reproduction, the audio data signal stored in the memory unit 4 is reproduced via the voice input / output unit 2 via a bus. At this time, the display portion 3 indicates this driving state (recording and reproduction).

In addition, when connected to the external personal computer 10, the voice data stored in the memory unit 4 is stored in the memory unit of the personal computer 10. On the contrary, the voice data stored in the personal computer 10 is stored in the voice recorder 10. The voice recorder performs the same function as that of the conventional voice recorder as described above.

The present invention converts the scanned data into a character and outputs it as a voice signal when scanning an image, and transmits and receives the data in connection with a personal computer. I have a function.

2 is a flowchart illustrating a process of converting image data into character data after image scanning in the present invention.

If the processing flow chart is not in the scanning state at step S2 of determining whether or not scanning is selected first, the flow proceeds to FIG. 4 and proceeds to the voice conversion mode determination step S42, in the case of the voice mode, as described above. In step S46, if the voice conversion mode is not performed, the personal computer data is downloaded.

First, a case in which the scanning mode is selected will be described with reference to FIG. 2.

After performing the start step S1, it is determined whether the scanning mode is selected in step S2. This is determined by the switching of the switch of the key operating section (6).

When the scanning mode is selected, it is determined whether the single-line scanning is finished when scanning in the one-line image scanning start step S3 and the one-line image scanning and step S4.

In this manner, during line scanning, the process proceeds to steps S5 and S6, where it is determined whether an error occurs during scanning.

Usually, the error during scanning is mainly caused by the distance between the data to be scanned and the data, and the error due to the scanning speed during scanning. In the case of an error in the distance of the data, the step (S5) is performed through step (S5). Proceeding to S11), an error display or a buzzer is generated, and an error according to the scanning speed proceeds to step S11 through step S6 to generate an error display or a buzzer.

In this case, each error state may be displayed differently, and for simplicity, only the error state may be represented by the same display.

In this manner, during normal scanning, the process proceeds to step S7 to read the scanned data, and the data read in the memory storage step S8 is stored in the memory.

After that, the process proceeds to step S9, and it is determined whether or not to connect with the personal computer. At the time of connection, the process proceeds to step S10, where it is transferred to the memory of the personal computer 10 for storage.

This process saves the scanned information line by line as a scanning process regardless of whether the personal computer 10 is connected to the personal computer 10, and displays an error at the time of scanning to request the user to accurately scan.

In this manner, when the scanning of one line is completed, the process proceeds from step S4 to step S12, and after reading from the memory, the stored data is read into the scanning buffer, and in step S13, whether the data can be converted as a character or not. Will be checked.

This method can also be used by operating a widely used OCR program, and can determine whether or not abnormality by comparing the converted code.

If the data thus scanned cannot be converted into a character, the process proceeds to step S14 again. If conversion is possible, the image data is converted into a character and stored in the line buffer. In this case, when the image data is converted into the character character, the OCR program is performed to convert the image data.

In the next step S15, the presence or absence of data in the line buffer is determined. When the line buffer is empty, the next scanning process is repeated.

That is, even when image data is normally converted to character data in step S15, there is no data in the line buffer (that is, when scanning portions without characters), so that only when data is stored in the line buffer, FIG. Proceed to the program of.

2 illustrates a process of scanning and converting image data into character data, and a method of handling an error occurring during scanning, and storing data input to a scanning buffer in a line buffer through an OCR program during normal scanning. It includes the process.

3 is a flowchart illustrating a process of outputting the converted character data in FIG. 2 as an audio signal.

Therefore, in order to output the characters of English letters and Korean characters as voice signals, it is necessary to distinguish between English letters and Korean characters. Especially in the case of English letters, the phonetic symbols for words (WORD) are different, so it is necessary to use a technique for processing voice signals for each word. In the case of numbers or Korean characters, it is necessary to output a voice signal for each character.

That is, the data stored in the line buffer in FIG. 2 is read out until one line ends in step S16.

In step S17, one character is read, and in step S18, it is determined whether or not the English language. In the case of the English letter, it proceeds to a separate step S23 for pronunciation of each word and is stored in the English word buffer. Therefore, successive alphabetic characters repeat the above process, and when a blank character (space) or a Korean character is inputted, a word of one alphabetic character is completed. At this time, after checking again whether there is data in the word buffer in step S19, the process proceeds to the routine RT20.

In the routine RT20, the data is searched in units of words. If the corresponding data exists in the memory, the process proceeds to step S24 to output an audio signal corresponding to the English word to the outside. Then, the Hangul or numbers are determined through step S25, which will be described later.

However, if the data inputted in alphabetical units does not exist, it is necessary to output by one character, that is, alphabetical phonemes of A, B, ... of English. In this case, perform step (S21) to store the number stored in the English word buffer. After repeating the loop as many times as possible, an audio signal is output for each character at step S22.

For example, if there is a space after inputting in the alphabet word buffer in the order A, B, C, three loops are circulated in step S21, and the alphabet phoneme corresponding to A, B, C is cycled every time. Is output in step S22.

However, if the data determined in step S18 is not English, check again whether the data exists in the English word buffer, and if the buffer is empty, the data becomes a space (empty character) or a Korean character or number. If it is not an alphabetic character at S19, the process proceeds to step S25. In step S25, one character is read, and in the case of Korean characters or numbers, an audio signal for one letter or number is output through step S26. Will be done. If one character is an empty character, the process proceeds directly to step S27 to clear the English word buffer. Since English word buffer is used only for English words, it is possible to prevent unnecessary input of Korean characters or numbers into the word buffer, and even in the case of English letters, the voice signal for the word is cleared immediately after outputting the next word. This is to make sure that is input into English word buffer.

As a result, the routine (RT10) distinguishes between English words and Korean characters (including numbers), and outputs audio signals in units of individual characters in case of Korean characters and numbers. RT20) outputs an audio signal for each English word or outputs an audio signal as individual characters.

After that, it is judged again in step S16 whether or not the reading of the line buffer data has been finished, and after completion, it is determined in step S28 whether the English word buffer is empty. If there is data in the word buffer, the routine (RT20) is performed again to output an audio signal for an English word or character and to clear the English word buffer. After that, the line buffer is also cleared in step S31, and then the repetition function of jumping to the position A in FIG. 2 is performed.

Finally, after scanning in FIG. 2 and storing the scanned data in the line buffer, in FIG. 3, it is determined whether the data stored in the line buffer is an English letter or a Korean character (including numbers). The audio signal can be output in word units, and the characters output in Korean letters, numbers, and individual English letters can be output by individual letters.

In FIG. 2, when it is determined in step S2 that it is not the scanning mode, it jumps to the point B of FIG. 4, and in step S41, it is determined in step S41 whether the voice transform mode is recognized or not. It performs the same function as a conventional voice recorder.

However, if it is not the voice conversion mode, data download is performed to receive data from the personal computer 10 in step S42. At this time, after all the data has been downloaded in step S43, if step S50 in which the play key is operated in step S50 is performed, step S45 is performed until the data of the document file is read and finished. As described above, the routine (RT20) of FIG. 3 performs English distinction for each word and outputs a voice signal corresponding to the word data, and a word not included in the data outputs an alphabet voice signal for each character. In the case of Korean letters or numbers, a voice signal corresponding to each letter or number is output. After outputting the downloaded data in this way, if it is determined in step S44 that it is determined that the English word buffer is empty (S47), the step S48 is selected accordingly to execute the routine RT10 of FIG. After selecting whether or not to clear the English word buffer (S49) and jumps back to A of FIG.

That is, in the case of Figure 4 it is determined whether the voice conversion mode to perform the same function as the existing voice recorder, or the character data downloaded from the personal computer 10, the character data for English letters, Korean characters, numbers, etc. as a voice signal In this case, there is no need to perform a separate scanning procedure.

As described above, the present invention can determine the switching state of the key control unit 6 and, in the case of the voice conversion mode, can perform the functions of the existing voice recorder as it is. By providing a chart, even in the case of an image character, it can be converted into a character character, and in the case of English letters and Korean characters (numbers), all characters can be output by voice in a different data processing order.

As described above, the present invention is capable of outputting voice to text data by combining an image scanner while performing a function of a conventional voice recorder. It can be effective.

In the case of the voice output of English letters and Korean characters, the voice signal of each letter is output in the case of English letters, and the voice signals of each character are output in case of Korean letters or numbers. In the case of English, the words are output by words, so you can listen to the voice more effectively.

In addition, since data can be exchanged with a personal computer and the text data can also be output as a voice signal, there is an advantage that a character input through the keyboard of the personal computer can be heard as a voice signal.
