A material having, for example, paper, synthetic paper,
Alternatively, it is a coating material having heat permeability and opacity such as color cellophane, and the starting end portion, the middle portion, of both width direction end edges thereof,
It is glued to the thermal paper at the terminal end or the like, and is fixed so that the coated paper can be easily peeled and opened with a fingertip after being ejected from the facsimile.

As shown in FIG. 4, the sheet feeding unit 13 is rotated by a motor 16 driven by a sheet feeding control unit 43 via a clutch provided in correspondence with the sheet feeding unit. Further, the transfer rollers 18 and 19 are provided, and the motor and a predetermined clutch are driven based on the output of the paper feed control unit so that the confidential paper CP is passed between the printing units 14. Reference numeral 20 is a reception stacker.

The printing unit 14 prints dots by a thermal recording method, and a print control unit of the CPU 4 which receives a paper start edge detection signal from the paper sensor 21 provided immediately before through the I / O unit 3. 44 prints on a predetermined position of the paper carried out by the paper supply unit 13. Therefore, the addressee of the facsimile transmission is printed on the header portion 15 of the confidential sheet.

In the embodiment of FIG. 4, a cut CP cut into a fixed size is used as a confidential sheet, but as illustrated in FIG. 5, roll paper (roll-shaped thermal paper) RP is provided at a fixed size. It is also possible to use a structure in which the coated paper is fixed so that the thermal paper is exposed corresponding to the header portion. When the roll paper is used as described above, the cutter 22 is provided on the downstream side of the printing unit 14.

The above-mentioned facsimile that prepares only confidential sheets is a confidential type facsimile. Such a fax machine can be used when the demand for confidential functions increases.
It is valid.

Next, a combination type embodiment having a conventional reception and recording function will be described. FIG. 6 is a block diagram corresponding to FIG. 1 showing an example of a combined-type facsimile machine. The same components as those of the dedicated type facsimile machine are designated by the same reference numerals, and overlapping description will be omitted. .

The analysis unit 42 analyzes the received electronic message, determines whether or not there is a confidentiality instruction command, and analyzes the electronic message content to be printed from the received electronic message as in the conventional case. When the presence / absence of the confidentiality instruction command is determined as a result of the presence / absence of the confidentiality instruction command, the confidentiality instruction signal a ₁ is given to the paper feeding control unit 44 as in the above case, and thus the paper feeding control unit 43 causes the I / O unit 3 to operate. A control signal c ₁ for driving the first paper feeding unit 13A is output via the. When there is no confidential instruction command, the non-instruction signal a ₂ is input to the paper feed control unit 43, and at this time, the paper feed control unit 43 outputs the control signal c ₂ for driving the second paper feed unit 13B. It is supposed to do.

The electronic message content b to be printed which is analyzed by the analysis unit 42 is given to the print control unit 45. The print control unit 45 outputs a control signal d for driving the print unit 15 via the I / O unit 3 according to the content of the electronic message input.

Confidential sheets CP similar to those in FIG. 4 are piled up and stored in the first sheet feeding section 13A. The second paper feed unit 14 includes normal paper UP, that is, a standard size,
For example, A4 size thermal paper is piled up and stored.

First sheet feeding section 13A and second sheet feeding section 13B
As shown in FIG. 8, the feeding roller is rotated by a common motor 16 driven by the sheet feeding control section 43 via a clutch (not shown) provided corresponding to each sheet feeding section. 17a, 17b, conveying rollers 18a, 18b,
18c and 19 are provided, and the motor and a predetermined clutch are driven based on the output of the paper feed control unit 43 so that the selected confidential paper CP or normal paper UP is passed between the printing units 14. Has become.

As described above, in this facsimile, after communication with other facsimile becomes possible,
The received data is analyzed at the beginning to determine whether or not there is a confidentiality instruction. If the confidentiality instruction is present, the confidential paper CP of the first paper feeding unit 13A is carried out and the subsequent transmission contents are recorded. If there is not, the confidential paper CP of the second paper feed unit 13B is unloaded and the subsequent transmission contents are recorded, and in any case, the confidential paper CP is discharged to the reception stacker 25.

FIG. 9 shows another embodiment of the combined type. In this embodiment, roll paper is used as the normal paper UP.
Also in this case, the basic configuration is the same as that of FIG. 8 except that the cutter 22 is provided for cutting the roll paper for each page.

FIG. 10 shows that in the combined type, only one type of roll-shaped ordinary paper UP is provided and there is a confidential instruction,
In any of the cases where there is no printing, the printing unit 14 prints using this paper, and when there is no confidentiality instruction, the recording paper that has passed through the printing unit is discharged to the reception stacker 20 as it is by the control similar to the conventional one. If there is a confidentiality instruction, the covering portion 23 provided between the printing portion and the discharge roller 19 physically covers the portion other than the header portion of the recording paper that has passed through the printing portion, and An example of making the received contents invisible will be shown.

The covering portion 23 of this example is equipped with an opaque covering material SP such as roll-shaped paper, synthetic paper, plastic film, etc., which can be rewound freely, and is driven by a drive source common to or independent of the paper UP transport system. Driven transport roller 18
b and a cutter 22 ', and a feed roller 23a and a doctor blade 23b for supplying glue to the roller that comes into contact with the upper surface side of the coating material of the transport roller 18b. Reference numeral 23c is a pressing roller that is brought into contact with and separated from the pressure receiving plate 24 by means of electrically controlled driving such as a solenoid 23d. Normally, the coating material separated from the pressure receiving plate and pasted by the pasting mechanism is a recording paper. Have been evacuated from the transport path. If the received electronic message includes a confidentiality instruction command, when the header portion of the recording paper that has passed through the printing unit 14 passes through the covering position by the pressing roller, the solenoid is operated and the covering material SP is It is glued to the recording paper. The gluing in this case is performed in order to remove the covering material from the recording sheet again and attach it in a peelable manner so that the printed contents can be read.

Since the printed portion is physically covered in the embodiment shown in FIG. 10, the printing method of the printing section does not need to be limited to the thermal recording method.
Any method such as an inkjet method can be used.

Further, similarly, in FIG. 11, regardless of the presence or absence of a confidential instruction, the received electronic message is printed on the roll-shaped recording paper RP, and the print content is transferred to a portion other than the header portion while being conveyed toward the receiving stacker 20. An example in which a means for coating with a coating agent is provided in the above portion is shown. That is, a means for adhering the liquid coating material from the tank 25 to the application roller 27 from the tank 25 via the feed roller 26 is provided on the downstream side of the printing unit 14, and when the confidentiality instruction command is not received, the application roller 2
When 7 is separated from the pressure receiving roller 29 by the restoring force of the solenoid 28 and the confidentiality command is included, the solenoid 28 is energized so that the applying roller 27 is pressed against the pressure receiving roller 29. is there. The structure of the means for adhering the coating material to the recording paper is, instead of the roller,
The coating agent may be ejected by an ink jet method or a bubble jet method to be attached.

The coating material is, for example, a known material which is opaque under sunlight and transparent under light of a specific frequency (polarized light), or an opaque material at room temperature and a temperature lower than room temperature. Alternatively, known materials that become transparent at elevated temperatures can be used. As a result, after the confidential message is printed, the covering material is attached to the recording paper other than the header portion, and the contents of the text cannot be seen. For fax machines using this coating,
Before the receiver sees the received contents, a polarization projector for projecting polarized light on the recording paper or a heater for heating the recording paper to a low temperature or a high temperature may be prepared and placed.

As described above, when the facsimile according to the present invention receives the confidential instruction, it is recorded on the recording paper by the memory reception or the immediate reception, and the recording paper is recorded in the header portion. Since only the addressee can be seen and the content of the text is covered with the coated paper or the coating agent, the content of the text is not seen by anyone other than the addressee when it is discharged to the receiving stacker of the facsimile. Further, looking at the header portion, a person other than the addressee can deliver the recording paper to the addressee. The addressee can see the contents recorded in the text section of each page by peeling off the coated paper, projecting polarized light on the recording paper with a polarization projector, or heating with a heater. it can.

Since only the addressee recorded in the header is exposed on the confidential sheet, the recording sheet is delivered to the addressee without seeing the transmission contents by the person who takes it out from the facsimile. Only peel off the coated paper, i.e.
The contents of the transmission can be viewed by opening the package, and the confidential function is achieved.

[0038]

As described above, the facsimile apparatus according to the present invention analyzes the electronic message received with another facsimile apparatus to determine whether or not there is a confidentiality instruction, and if there is an instruction, the header section. Since only the address printed part of the text is visible and the text printed part is covered so that it is not visible to the outside, it is possible to reliably send to the addressee without the contents being seen by anyone other than the addressee, and thus the confidential function In addition to being able to realize, it is possible to quickly confirm the received contents without having to wait for the troublesome work such as inputting a personal identification number and the elapse of the printing time.

Further, in this facsimile, the conventional paper feed unit is used as it is, or another paper feed unit is added, and a function of analyzing the presence / absence of a confidentiality instruction command in the analysis unit of the control unit (CPU) and a paper feed unit are provided. By simply adding a function to newly control the control section, or by adding a coating agent attaching means,
The confidential function can be realized with a relatively simple configuration and control.
