[Problems to be solved by the device]

 By the way, in the above-mentioned conventional facsimile apparatus, since the journal data is encoded and the encoded data is stored in the storage device, there is a problem that a storage device having a large storage capacity must be used.

When a journal is printed based on the coded data stored in the storage device, the coded data is decoded and a character pattern corresponding to the decoded data is generated. Therefore, there is a problem that it takes time to process the data for printing the journal.

This invention has been made to solve the above-mentioned conventional problems, and the purpose of this invention is to convert a character pattern generated by a character pattern generation means based on journal data into line data. The journal data is converted and stored to store the compressed data obtained by compressing this line data.When printing the journal, the compressed data is read and expanded to convert it to the original line data. However, by printing a journal based on this, it is possible to store a large amount of journal data, and to provide a facsimile device that can shorten the data processing time for printing a journal. .

[0012]

[Means for Solving the Problems]

 The facsimile device of the present invention is a facsimile device that includes a reading device and a recording device that prints and outputs received image information, and that prints and outputs journal data as needed. A journal compressed data storage means for converting the character pattern generated by the above into line data and storing the compressed data obtained by compressing the converted line data, and the above journal compressed data storage means for printing the journal. The constitutional feature is that the apparatus has a journal printing unit that reads the compressed data stored in the memory, decompresses it, converts it into the original line data, and prints the journal based on this.

[0013]

[Action]

 A facsimile apparatus according to the present invention converts a character pattern generated by a character pattern generating means into line data based on journal data, and stores compressed data obtained by compressing the line data to store the journal data. When the data is saved and the journal is printed, the compressed data is read, decompressed and converted into the original line data, and the journal is printed based on this. Therefore, since compressed data is stored instead of storing encoded data that is encoded journal data, a large amount of journal data can be stored without using a storage device having a large storage capacity. Further, the compressed data is expanded, and the journal is printed using the expanded data, so that the data processing time for printing the journal can be shortened.

[0014]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the facsimile machine of this embodiment. In the figure, this facsimile device includes a microprocessor 1, a reading unit 2, a recording unit 3, a compression / expansion processing unit 4, a panel unit 5, a ROM 6, a RAM 7, a character generator 8, a modem 9, a communication control unit 10, and a calendar timer. 11, a system bus 12 is provided.

The microprocessor 1 performs overall system control, image information transfer control processing, and the like. The reading unit 2 reads a document or the like with an image sensor such as a CCD and outputs image information. The recording unit 3 records the sent image information on recording paper. The compression / expansion processing unit 4 performs a compression process on the image information sent to the destination, or performs a decompression process on the sent image information. The panel section 5 is provided with a plurality of keys such as a telephone number of a transmission destination and a transmission key for performing a transmission operation. The ROM 6 is a memory in which a program for performing system control of the entire facsimile apparatus and various data are stored. The RAM 7 is used as a transmission buffer memory and a reception buffer memory, and is a memory used for storing journal data. The character generator 8 generates and outputs a corresponding character pattern based on the input journal data.

The modem 9 is a circuit that demodulates image information sent via a telephone line and outputs it to the communication control unit 10, or modulates image information to be transmitted and outputs it to the telephone line. The communication control unit 10 is a circuit for reading communication control information in a signal sent through a telephone line, performing processing such as transmission control error control, and storing journal data in the RAM 7. is there. Reference numeral 11 is a calendar timer, which is a circuit for generating and outputting time information at the time of communication. Reference numeral 12 is a system bus including a data bus and an address bus.

Next, processing of journal data when transmitting and receiving image information such as a document in this facsimile apparatus will be described with reference to the flowchart of FIG.

First, the sender sets the original on the reading unit 2 and inputs the telephone number of the destination of the original from the panel unit 5. The input destination telephone number is encoded by the BCD code and then stored in the RAM 7. Next, when the transmission key of the panel section 5 is operated, the destination telephone number stored in the RAM 7 is converted into a pulse signal and sent to the telephone line, and the telephone line between the destination and the source is connected. The reading unit 2 reads image information from a document. The image information read from the original is subjected to compression processing and the like by the compression / expansion processing unit 4, and then sent out to the telephone line from the communication control unit 10 via the modem 9 (step S1).

On the other hand, when the telephone line is connected to the destination, the time information at the time of connection is read from the calendar timer 11 and further encoded as journal data. Further, information on the number of transmitted originals is also encoded as journal data (step S2).

The coded data of the time information and the number-of-images information is input to the character generator 8. As a result, as shown in FIG. 3, the character generator 8 generates and outputs a character pattern in which one character corresponding to the input data is decomposed into vertical (row) horizontal (column) m × n pixels (step S3).

The character pattern output from the character generator 8 is divided into line data for each row position (step S4), and further compressed for each line data by the modified Huffman compression method (step S5). The data is stored in RAM 7 (step S6). As a result, the compressed character pattern corresponding to the compressed journal data is compressed and stored in the RAM 7 by the modified Huffman method.

Next, a process for printing a journal will be described based on the flowchart shown in FIG.

When printing a journal, the journal print key of the panel unit 5 is operated. Then, the data compressed by the modified Huffman method and stored in the RAM 7 is read for each line data (step S11). The compression / decompression processing unit 4 decompresses the compressed data read from the RAM 7 line by line (step S12) and converts the original pixel data line by line (step S13). ) Generates a character pattern in which one character is decomposed into vertical (row) and horizontal (column) m × n pixels. Then, according to the character pattern, the recording unit 3 prints a journal (step S14).

In the above-described embodiment, the case where the journal data is the telephone number of the destination, the communication time information, and the number of transmitted originals has been described. However, when the sender name and the destination are foreign countries, It may be configured such that necessary data such as the destination country name is used as the journal data.

Further, the method for compressing the character pattern corresponding to the journal data is not limited to the modified Huffman compression method, and other compression methods may be used.

[0026]

[Effect of device]

 As described above, according to the present invention, the compressed data obtained by compressing the character pattern corresponding to the journal data is stored to save the journal data, and when the journal is printed, the compression is performed. The data is read, the original character pattern corresponding to the journal data is restored by decompression, and the journal is printed based on this. Therefore, since the data obtained by compressing the character pattern corresponding to the journal data is saved, a large amount of journal data can be saved without using a storage device with a large storage capacity, and the journal is printed. Occasionally, decompression processing is performed on the compressed data without going through the character generator, and journal printing is performed using the resulting character pattern, so the data processing time for journal printing can be shortened. .
