The present invention relates to a method of recording and reproducing voice data in a facsimile system, and in particular, in a facsimile with an auto-response function, when recording image data, information voice data is additionally recorded on a recording sheet, and the recorded voice data is scanned and recorded in the order of recording. A method of recording and reproducing voice data for sorting and reproducing.

In general, a facsimile apparatus is an office automation apparatus capable of transmitting or receiving various documents and photographs to a remote party using a telephone line. The office automation equipment is required not only one function but also various functions as a complex office equipment according to the development of industry and diversification of information. The demand for such a complex function is a trend that a facsimile system is being developed as a complex office device including an automatic answering function as well as a printer function of a personal computer.

The automatic answering device can be broadly classified into an analog answering device using magnetic tape as a recording medium for voice signals and a digital answering device using a semiconductor memory such as DRAM (Direct Random Access Memory) or ARAM (Audio Random Access Memory). .

Recently, due to the rapid development of semiconductor memory, an automatic answering device that is easy to write or read data has been mainly developed. In the conventional autonomous answering device using a semiconductor memory, since a volatile memory device that loses recorded data is mainly used when power is not supplied, a time limit for data storage and a storage capacity of the memory device are not sufficient to store a large amount of data. There was this limit. In order to solve such a problem, a technology for recording and reproducing voice data on a recording paper in a facsimile apparatus is disclosed in Korean Patent Application No. 28582. As described above, when the recording paper reproduces the audio data in the form of a space and a bar, it is impossible to reproduce the correct audio data when the recording papers recording different audio data are mixed or the recording papers to be read are out of order.

Therefore, an object of the present invention is to record the recording data using the additional data recorded during playback after recording additional recording date and time and recording page in the data recording area when recording the voice data on the recording paper in the facsimile apparatus to solve the above problems It is to provide a voice data recording and reproducing method of reproducing the correct voice data by sorting when mixed.

The CPU 10 controls the overall operation of the facsimile according to the set program. After recording the recording information such as the recording date and time and the recording page in the data recording area of the recording paper, the CPU 10 controls to record the received audio signal on the recording paper. By scanning the information, when the other voice information is mixed or the pages are mixed, the information is rearranged to control to reproduce the correct voice signal. The memory 12 stores a program for recording and reproducing voice data, and temporarily stores data generated when the program is executed. OPE (OPERATING PANNEL) 14 has a plurality of keys, applies key data according to the pressing of the keys to the CPU 10, and displays the operation state under the control of the CPU 10. The scanner 16 scans an original, converts an image of the original into binary information, and applies it to the CPU 10. Under the control of the CPU 10, the modem 18 performs analog modulation on the transmission data and demodulates the analog reception data. The network control unit (NCU) 20 is operated under the control of the CPU 10 to form a call loop of a telephone line, and interfaces the signal of the modem 18 with the signal of the telephone line. The printer 22 prints the image data on the recording sheet under the control of the CPU 10. The codec 24 converts an analog voice signal input through the NCU 20 into a digital signal and outputs the digital voice signal to the voice processor 26, and converts the digital voice signal into an analog voice signal and outputs the analog voice signal to the NCU 20. The audio amplifier 28 amplifies the voice signal converted from the analog signal from the codec 24 to a predetermined level and outputs the audio signal to the speaker 30. The voice processing unit 26 is composed of a DSP (Digital Signal Processor), and can be implemented using, for example, a DSP D6375A. The voice message stored in the memory 12 under the control of the CPU 10 is synthesized and outputted to the codec 24.

1 to 5, the operation of the preferred embodiment of the present invention will be described in detail.

For Group 3 facsimile systems that can send and receive ISO (International Standards Origanization) A4 size (210mm ?? 297mm) manuscripts, the image playback area recommended by CCITT Recommendation T.4 is used for printing and scanning. Taking into account possible horizontal and vertical losses, 196.6mm ?? It is recommended to ensure a range of 281.46 mm. Reading of the image reflects the light generated from the light source to the document, and detects the reflected light by the read sensor. CCD (Charge Coupled Device) chip or CIS (Contact Image Sensor) is mainly used as a read sensor, and is composed of optical sensors arranged at intervals equal to the horizontal resolution of Table 3 above. Optical sensors that read documents of ISO A4 size (210mm ~ 297mm) generally have a reading width of 216mm to read up to documents of Letter Size (216 ~ 279mm), and the reading sensor is about 216mm horizontally. There are a total of 1728 optical sensor arrays at intervals of 8 / mm.

In addition, a fluorescent lamp or an LED array is used as the light source. The recording method is classified into thermal recording method and general paper method according to the printed paper. The horizontal resolution recorded is 3.85 lines / mm as standard and 7.7 lines / mm and 15.4 lines / mm as an option. The Group 3 facsimile system supports recording up to 7.7 lines / mm vertical resolution.

The facsimile system of the present invention having such a resolution has an answering machine function, which is the same technique as is commonly used in an answering machine. According to the present invention, the voice signal received from the calling part is stored in the voice memory by the automatic answering function. The data stored in the voice memory is converted into a code sheet as shown in FIG. Referring to FIG. 3, an operation of converting a voice signal stored in the voice memory into a code form as shown in FIG. 2 and printing it on a recording sheet is described. First, in step 101, the CPU 10 checks whether a ring signal is detected from the NCU 20. When the ring signal is detected, the process proceeds to step 102. In step 102, the CPU 10 checks whether the voice reception mode is set by the key input unit of the OPE 14, and proceeds to step 103 if the voice reception mode is not set. In step 103, the CPU 10 performs a function according to the set mode. In other words, if the TEL mode is set, the handset is hooked off to make a telephone call. If the fax mode is set to FAX, FAX documents are received. However, if the voice reception mode is set in step 102, the CPU 10 controls the voice processing unit 26 to read the voice signal stored in the memory 12 and then the voice synthesis voice guidance message (OUT GOING MESSAGE: OGM). ). The transmitted voice guidance message is converted into an analog signal through the codec 24 and transmitted to the calling part through the NCU 20. After transmitting the voice guidance message, when the user of the calling part inputs the voice message, the CPU 10 controls to receive the voice data in step 105. In this case, the received voice data is received through the NCU 20, converted into a digital signal by the codec 24, and applied to the voice processor 26. Then, in step 106, the CPU 10 controls the voice processor 26 to compress the digitally converted voice data and store it in the memory 12. Thereafter, in step 107, the voice data reception is terminated. If the voice data reception is not finished, the flow returns to step 105 to repeat the above-described operation to receive and store the voice data. However, if the reception of the voice data is finished, the CPU 10 proceeds to step 108 and the CPU 10 stores the recording date and time in the memory 12 and proceeds to step 109. In step 109, the CPU 10 reads and stores the recorded recording date and time, and prints the total number of pages and the currently printed page number in the information recording area at the top of FIG. Then, in step 110, the CPU 10 reads data about the recording date, recording time, data amount, current page number, and total number of pages from the memory 12 in the first line of the data recording area and prints them in space and bar form. . In step 111, the CPU 10 prints the received voice data stored in the memory in a space and bar form as shown in FIG. 2 and proceeds to step 112. FIG. After reading the voice data stored in the memory 12, the printer 22 is controlled to print one page of data. The print portion is composed of a heading for the recorded audio data, an information recording portion for recording information, and a data recording portion for recording audio data. The margin was determined by considering the effective printing area and the effective scanning area given by the structural characteristics of the facsimile system. The structure of the information recording section is composed of an information recording baseline, a heading for print content as an information recording area, reception date and time of audio data, page information of recorded data, a data recording start line, and the like. For the recording of audio data, 0 and 1 binary data are recorded, and 0 data is recorded as a space and 1 data is recorded as a bar. One line is recorded with the space and bar notation of data combined with 0 and 1, and data is continuously recorded on a new line when the continuous data recording exceeds one line. In recording data on a new line, a space between lines is inserted between the lines on which data is recorded to distinguish the data from the previous line. When the printing of one page is completed, the CPU 10 checks whether the printing is finished in step 112, and if the printing is not finished, the CPU 10 proceeds to step 109 to repeat the above-described operation to print the next page. When printing is finished in step 112, the program ends.

As described above with reference to FIGS. 4 and 5, after the audio data is printed on the recording sheet in a space or bar form, the printed document is scanned and reproduced as an audio signal. It is checked whether or not the voice reproduction key is input from the key input unit of step 14. In this case, when the voice reproduction key is input, the process proceeds to step 201, where the CPU 10 controls the scanner 16 to read the image data of the original and receive the binarized image data. The CPU 10 then stores the read binarized image data in the memory 12 in step 202. In step 203, the CPU 10 checks whether the original reading is completed, and returns to step 201 if the original reading is not completed, and proceeds to step 204 if the reading of the original is completed. In step 204, the CPU 10 analyzes the entire page information. The full page information analyzes the total page number information of the first line recorded in the data recording area. At this time, in step 105, the CPU 10 checks whether or not the read original is plural pages. If it is not a plural page, the CPU 10 proceeds to step 212 to synthesize and reproduce the voice data recorded in the original through the voice processing unit 26. However, if the read manuscript is plural pages, step 206 is performed. In step 206, the CPU 10 analyzes recording date and time information of each page. In step 206, if the recording date and time of each page is not the same. However, if the recording date and time are the same, the process proceeds to step 209 where the CPU 10 checks whether the page order is normal. That is, it is checked whether the originals are read in the page order, and if it is read in the page order, the flow proceeds to step 212. If it is not read in page order, however, proceed to step 210. In step 210, the CPU 10 checks whether there is a missing page. If the missing page exists, the CPU 10 processes an error in step 208 and ends the operation. However, if there are no missing pages, sort the pages in step 211 and proceed to step 212. In step 212, the CPU 10 reproduces the voices in the order of page order. Referring to FIG. 5, the subroutine operation for reproducing the voices is performed. In step 301, the CPU 10 analyzes the recording date and time data recorded in the information line. In step 302, a time stamp function is performed. That is, the voice data for recording date and time are guided by voice synthesis by analyzing the time data on which the voice signal is recorded. For example, the voice signal for recording date and time may be voice data recorded at 00: 00 on April 10, 1997. Then, in step 303, the CPU 10 synthesizes the audio signal recorded on the data line and reproduces the audio signal for one page. In step 213, the CPU 10 checks whether or not the voice play is terminated. If the voice play is not finished, the CPU 10 returns to step 212 to play the next page, and repeats the above-described operation to play the voice and ends the program when the voice play ends.

As described above, the present invention records the information data in the first line of the data recording area when the audio signal received from the facsimile with the automatic response function is stored on the recording paper, and then analyzes the information data during playback. When mixed with other recording papers or when the page order is changed and read, the page order is reproduced so that an accurate audio signal can be reproduced.
