Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a storage device capable of maintaining confidentiality.

[0002]

2. Description of the Related Art In recent years, the amount of data entering a facsimile machine is gradually increasing, and the amount of data is increasing.
On the other hand, the consumption of recording paper for printing is also increasing. Along with this, the recording paper often disappears during reception of the facsimile, and for example, there has been a facsimile apparatus provided with an IC memory or the like for backing up facsimile contents.

Further, there is also a device in which instead of printing on a recording sheet, writing is performed in a storage device and a liquid crystal display (LCD) or the like is used to display it.

[0004]

[Problems to be Solved by the Invention] However, the number of facsimile receptions per day is increasing in the future, and the amount of data information which is the content of each input item is also large, and the content is printed on a printer. If it is output, a large amount of recording paper is required, and time is wasted in its storage and sorting. In addition, sorting a large number of facsimile input items also requires a large amount of work.

Further, the printed recording paper is inconvenient in terms of security. On the other hand, even if it is stored in a storage medium such as a floppy disk, it may be inconvenient in terms of confidentiality.

The present invention has been made by paying attention to the above problems, and scrambles a large amount of facsimile input data and voice data, stores them in a storage medium, and retrieves the above information as necessary. , To obtain a visible and confidential facsimile machine.

[0007]

According to the present invention, there is provided index generating means for generating index data of facsimile signals and voice signals, scrambler means for scrambling the data of the facsimile signals and voice signals, a storage device, and Data input control means for storing the output of the index generating means and the scrambler means in the storage device, index selection means for searching and selecting the index data, descrambler means for descrambling the data in the storage device, Data output control means for outputting search / selection data from the storage device and restoring and outputting the data via the descrambler means.

[0008]

When the signal is input from the communication line, the operation is as follows. Under the control of the data input / output control means, the modem section detects an input signal from the communication line. Next, the index data of the facsimile signal and the voice signal inputted from the communication line accumulated by the index generation means, the facsimile signal converted by the modem section and the A /
Data obtained by combining the scrambled data of the D-converted audio signal is sequentially stored in the storage device in the order of reception.

On the other hand, when the received data stored in the storage device is searched and it is desired to display or print the received data, the process is as follows. The data input / output control means receives the request instruction from the input means such as a keyboard. The input operation from the keyboard is displayed on the display device. That is, a list of items received by the index selection means via the input means is displayed in the order of input, and the items are searched and selected. The incoming time, the other party's telephone number, etc. are displayed in each item. Data corresponding to the selected item is output from the storage device, and the data is restored and displayed via the descrambler means. If the restored data is a facsimile signal, print it out on a printer,
If it is a voice signal, it is converted to an analog signal by D / A conversion and the voice is output from the speaker.

Is a scrambler circuit that scrambles digital signals,
Reference numeral 5 is an index / generation circuit for accumulating and storing the index data such as the reception time of the facsimile signal and the telephone voice signal received from the communication line and the calling telephone number for each input item, and searching them and generating the selection item. Received data storage device (eg floppy disk device),
7 is a descrambler device, 8 is a display device, 9 is a keyboard, 10 is a changeover switch circuit, 11 is a printer (for example, a thermal printer), 12 is a D / A conversion circuit, 13
Is a speaker and 14 is a timer circuit.

Reference numeral 15 is a data input / output control circuit. Under the control of the data input / output control circuit 15, the modem circuit 2 detects an input signal from the communication line,
The control circuit combines data input control until data is stored in the received data storage device 6 and data output control until data output is requested from the keyboard 9 and output to the printer 11 or the speaker 13.

The operation of FIG. 1 is as follows. The index / generation circuit 5 detects an input signal from the communication line and generates an incoming time and a destination telephone number of the facsimile signal and a voice signal including an answering machine as index data. When the input signal data from the communication line is a facsimile, it is converted into a digital signal by the modem circuit 2 and is scrambled by the scrambler circuit 4. On the other hand, when the input signal data from the communication line is a telephone voice signal, it is converted into a digital signal by the A / D conversion circuit 3 without passing through the modem circuit 2 and scrambled by the scrambler circuit 4. Here, the index data and the scrambled digital data corresponding to the index data are combined by the data input / output control circuit 15 and sequentially stored in the received data storage device 6 such as a floppy disk in the order of reception.

As described above, since a large amount of received data input one after another from the communication line is sequentially stored in a recording medium such as a floppy disk, it is not necessary to print it by a printer each time. Only the selected items should be printed on the printer. Further, since a large amount of received data on a recording medium such as a floppy disk is all scrambled, confidentiality can be maintained even if this recording medium is copied.

On the other hand, the data input / output control circuit 15 detects an input signal from the keyboard 9 and requests a password from the keyboard. If the passwords match, the data input / output control circuit 15 determines whether to operate the descrambler circuit 7. Next, the data input / output control circuit 15 retrieves the data content matching the selected item from the index data stored in the received data storage device 6, and outputs all the received data of the matched index to the descrambler circuit 7. The result is displayed on the display device 8.

When the data content is a facsimile signal, it is output to the printer 7, and when the content is a telephone voice signal, the data input / output control circuit 15 causes the changeover switch circuit 10 to shift from the printer 11 side to the D / A conversion circuit 12 side. Switched
The digitized telephone voice signal is converted into an analog signal and output to the speaker.

As described above, it is not necessary to display all the facsimile data and telephone voice signals stored in the recording medium such as the floppy disk and to see them. First, the index data table is searched, and the table is searched. You only need to select the items, which makes it time efficient. If the necessary items are selected, the display may be made only in the case of the facsimile, or the printout may be made. In the case of a voice signal, it is output to the speaker, but it can also function as an answering machine. The operation is easy to understand.

[0017]

As described above, according to the present invention, after facsimile data and telephone voice data are scrambled to a storage device such as a floppy disk having a large storage capacity and capable of additionally storing as many storage media as desired. The remarkable effect is that the index data can be combined and recorded, these data can be randomly accessed, and only the necessary items can be descrambled and restored, and the facsimile signal can be output to the printer and the telephone voice to the speaker. Play.
