Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having electrophotographic recording means for recording image information on ordinary roll paper, and particularly for receiving image information when heat sensitive roll paper is set by mistake. It concerns the prevention of loss.

[0002]

2. Description of the Related Art As a method of transferring image information received by a facsimile apparatus to a recording sheet, a heat-sensitive type or a thermal transfer type using a thermal head has hitherto been widely adopted. As described above, in the recording system using the thermal head, a thermal paper having a color-developing layer that develops color when heat is applied is used. If plain paper is used in a facsimile machine that uses this thermal paper, the received image information cannot be transferred. Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 62-256560, a paper feeding unit to a recording unit cannot be transferred. A heating head and a color detection sensor are provided in the recording paper path leading to a certain thermal head, and the surface of the recording paper sent from the paper feed section is heated by the heating head, and a color detection sensor is used to detect the presence or absence of color development on the heated recording paper. If the thermal paper is set to the facsimile machine using the thermal head, it is determined that the thermal paper is used when the color is detected, and if the thermal paper is not used, the plain paper is used. I am detecting. When the thermal paper is not set, the reception side displays that the recording paper is not set correctly, and the transmission side is notified that communication is not possible to prevent omission of transmission.

Further, as a facsimile machine using an electrophotographic recording system for recording image information on plain paper, a facsimile machine capable of using plain roll paper instead of plain paper standard cut paper has been developed.

[0004]

However, the heat-sensitive roll paper is mainly used as the roll paper, and the heat-sensitive roll is mistakenly used in the facsimile machine which records the received image information on the ordinary roll paper by the electrophotographic recording method. -If you set and use
The heat of the heater in the fixing section of the electrophotographic recording system causes the color-developing layer to turn black and loses the received image information.

In order to prevent the received image information from being lost, for example, as disclosed in Japanese Patent Laid-Open No. 62-256560, a roll paper whose surface is heated when the received image information is recorded. Is detected near the facsimile machine even if an error message is displayed when the proper roll paper is not set by detecting the presence or absence of color development. There is not always an operator in
If the error display cannot be confirmed immediately, reception will be disabled for a long time.

The present invention has been made in order to solve the above disadvantages, and it is possible to reliably detect that the type of roll paper has been set incorrectly, and when the proper roll paper is not set. However, it is an object of the present invention to obtain a facsimile device that can be reliably received.

As shown in the configuration diagram of FIG. 2, the plotter unit 8 includes a laser exposure unit 81 having a laser diode, an fθ lens, a rotating polyhedron, a mirror, a transfer belt 821, a developing roller 823, and the like. And a fixing unit 83 having a fixing heater 831 and a fixing roller 832 for fixing the toner image transferred to the recording paper. It has a roll paper feeding section 84 for feeding the roll paper 17 as recording paper. The encoding / decoding unit 9 encodes the image data to be transmitted and restores the received image data. The communication control unit 10 decodes the communication control information and connects to an external line.

The color control unit 11 sets the roll paper 17 in the roll paper feeding unit 84 after the fixing cycle at the paper cycle after setting.
Energize the data. As shown in FIG. 2, the color-developing detection sensor 12 is provided in the subsequent stage of the fixing unit 83 and detects the presence or absence of color development on the recording paper. The recording paper determination unit 13 receives the detection signal from the color detection sensor 12 and determines whether the normal roll paper or the heat-sensitive roll paper is set in the roll paper feed unit 84. The output processing unit 14 stores the received image information in the image memory 5 when the recording paper determination unit 13 determines that the heat-sensitive roll paper is set in the roll paper feeding unit 84. The warning display unit 15 displays that the heat-sensitive roll paper is set in the roll paper feeding unit 84, and the buzzer 16 issues an alarm.

The operation when the roll paper is set in the roll paper feeding unit 84 in the facsimile apparatus 1 having the above-described structure will be described with reference to the flowchart of FIG.

The roll paper 17 set in the roll paper feeding section 84 disappears, and the roll paper 17 is replaced to replace the roll paper 17.
When the cover of the roll paper feeding unit 84 is opened / closed, the cover open / close sensor provided in the roll paper feeding unit 84 detects the cover opening / closing (step S1). When the cover opening / closing of the roll paper feeding unit 84 is detected, the paper cycle is started, and the roll paper feeding unit 84 shown by the arrow A in FIG. 2 passes through the transfer unit 82 and the fixing unit 83. A fixed amount of recording paper is sent out through the recording paper conveyance path (step S2). Simultaneously with the start of this paper cycle, the color forming control section 11 energizes the fixing heater 831 of the fixing section 83 to heat the fixing roller 832 (step S3). The recording paper is discharged through the heated fixing roller 832. Send out a certain amount of recording paper and
When the cycle is completed, the color control unit 11 causes the fixing heater 8 to
The current flowing through 31 is cut off (steps S4, S
5). When the operator confirms the recording paper discharged during this paper cycle, the roll paper feeding unit 8
It is possible to immediately know whether the normal roll paper has been set in 4 or the heat-sensitive roll paper has been set. That is, when the normal roll paper is set in the roll paper feeding unit 84, no color is developed even if it passes through the heated fixing roller 832, but when the heat-sensitive roll paper is set, it is not heated. Fixing Roller 8
The recording paper discharged through 32 is colored black, for example. Therefore, by simply observing the color of the recording paper ejected during the paper cycle, the set roll paper 1
You can know the suitability of 7.

When the suitability of the roll paper 17 set in the roll paper feed section 84 is judged by visual inspection of the operator as described above, sometimes the suitability of the roll paper 17 is not judged. In some cases, it may be erroneously judged. Therefore, when a heat-sensitive roll paper is set in the roll paper feeding unit 84, an alarm may be issued to call attention to the operator.

The operation in this case will be described with reference to the flowchart of FIG. The cover opening / closing sensor provided in the roll paper feeding unit 84 detects the cover opening / closing to start the paper cycle, and the color developing control unit 11 energizes the fixing heater 831 to fix the fixing roller. When la 832 is heated (steps S11 to S11)
S13), the color development sensor 12 detects the color development state of the recording paper sent from the fixing roller 832, and sends a detection signal to the recording paper determination unit 13. The recording paper determination unit 13 determines whether or not the entire recording paper sent from the fixing roller 832 is colored black, for example, based on the sent detection signal (step S14). If the entire recording paper sent out from the fixing roller 832 is colored black, for example, it is judged that the heat-sensitive roll paper has been set in the roll paper feeding section 84 and the roll is fed. A paper error signal is output (step S15). The CPU 2 sends the roll paper abnormality signal output from the recording paper determination unit 13 to the warning display unit 15, displays the roll paper abnormality on the warning display unit 15 and sounds the buzzer 16 for a certain period of time to operate the operator. Is notified of the roll paper abnormality (step S16). When the recording paper determination unit 13 determines the detection signal and the recording paper sent from the fixing roller 832 has no color, the roll paper feeding unit 84 sets the normal roll paper. Then, the roll paper normal signal is output (step S17). When the predetermined paper cycle is completed (step S18), the color control unit 11 cuts off the current flowing through the fixing heater 831 (step S19). When the roll paper abnormality signal or the roll paper normal signal is output and the current flowing through the fixing heater 831 is cut off, the CPU 2 puts the entire apparatus in a standby state.
When the roll paper abnormality signal is output, the CPU 2
The warning display unit 15 is provided until the cover opening / closing sensor detects that the cover of the roll paper feed unit 84 has been opened in order to replace the roll paper 17 set in the roll paper feed unit 84. To
The paper error is displayed.

As described above, when the roll paper 17 is set in the roll paper feeding section 84, it is immediately judged whether the roll paper 17 is suitable or not. When the heat-sensitive roll paper is set, the roll paper is abnormal. Is notified to the operator, the operator knows that the heat-sensitive roll paper is set before the facsimile reception and can replace it with the normal roll paper, and loses the received image information. Can be prevented.

When the heat-sensitive roll paper is erroneously set in the roll paper feeding section 84 as described above, the operator is immediately notified of that fact, but the operator still mistakenly sets the heat-sensitive roll. If the user does not notice that the roll paper is set, or if there is a facsimile reception before replacing the roll paper 17, the received image information will be lost. Therefore, if there is a facsimile reception at such time, the output processing unit 14
Temporarily stores all the received image information in the image memory 5, and displays the fact on the operation display unit 6. When the recording paper is determined to be normal by replacing it with the normal roll paper, the output processing unit 14
When the image information stored in the image memory 5 is automatically read out and output, or when the operator operates the operation display unit 6 after switching to normal roll paper, the image information stored in the image memory 5 Is read and output. Like this,
By storing the image information received when the roll paper is set by mistake in the image memory 5, the received image information is lost even if the operator does not notice that the heat-sensitive roll paper is set by mistake. You can be surely prevented from being exposed.

In the above embodiment, the image information received when the operator does not notice that the operator has set the heat-sensitive roll paper by mistake is temporarily stored in the image memory 5 and saved. However, in the case where the plotter unit 8 is provided with the roll paper feed unit 84 and the standard size paper feed unit 85 as shown in FIG. 2, when the heat-sensitive roll paper is erroneously set. Alternatively, the paper feeding may be switched from the roll paper feeding unit 84 to the standard paper feeding unit 85 and the recording paper may be fed from the standard paper feeding unit 85.

When the roll paper feeding unit 84 and the standard size paper feeding unit 85 are provided in this manner, the recording paper selecting unit instead of the output processing unit 14 as shown in the block diagram of FIG. 1
8 is provided. Then, as shown in the flowchart of FIG. 6, when there is a facsimile reception, the CPU 2 measures the number of lines of the received image information and calculates the image length from the line density (steps S21 to S23). The recording paper selection unit 18 determines whether the calculated image length is the same as the size of the standard paper set in the standard paper feeding unit 85 (step S24). When the image length and the size of the standard paper are the same, the standard paper is fed from the standard paper feeding section 85 and the received image information is recorded (step S25). When the image length and the size of the standard paper are different and the normal roll paper is set in the roll paper feeding unit 84, the recording paper is sent out from the roll paper feeding unit 84 to receive the received image information. It is recorded (steps S26 and S27). When the image length and the size of the standard paper are different and the roll paper abnormality signal is output from the recording paper determination unit 13 and the roll paper abnormality is displayed on the warning display unit 15, the standard paper is fed. The recording paper is sent out from the unit 85 and the received image information is recorded on the standard paper (steps S26, S).
25). As described above, when the thermal roll paper is erroneously set in the roll paper feeding unit 84, the plain paper recording paper is fed from the standard paper feeding unit 85. Therefore, the image information received at that time is sent. It can be output reliably.

In each of the above-mentioned embodiments, the case where the color information of the recording paper sent from the fixing roller 832 is judged to prevent the loss of the received image information is explained.
As shown in the block diagram of FIG. 7, the color detection sensor 12 that detects that the heat-sensitive roll paper is erroneously set is not provided in the subsequent stage of the fixing unit 8, and the image information received by the simple configuration is You can prevent it from being lost.

In this case, when the image information is received, the image information output section 19 outputs the received image information to a recording sheet and stores it in the image memory 5 with a management number. If the heat-sensitive roll paper is erroneously set in the roll paper feed unit 84 when the received image information is output to the recording paper, the output recording paper is all output in black. The operator who confirmed the output recording paper is the roll paper feeding unit 84.
After replacing the roll paper 17 set in (1) with a normal roll paper, the operation display unit 6 is operated to output the communication management report. Then, when the operator finds that there is image information that is not correctly recorded and output although it is received by the output communication management report, the operator confirms the management number,
The operation display unit 6 is operated to enter the image information output mode and the management number is input. When the image information output mode is entered and the management number is input, the received image information reading section 20 reads the image information of the corresponding management number from the image memory 5, sends it to the plotter section 8 and records it again on the recording paper. In this way, even if the heat-sensitive roll paper is erroneously set in the roll paper feeding unit 84, the received image information can be prevented from being lost with a simple structure, and the entire apparatus can be made inexpensive. can do.

As described above, the present invention provides a toner.
The fixing heater that fuses the image to the recording paper is energized during the paper cycle after the roll paper is set, and heat is applied to the recording paper during the paper cycle, causing the heat-sensitive roll paper to Since the heat-sensitive roll paper is made to color when set, whether the roll paper set when the roll paper is set is normal roll paper or heat-sensitive roll paper is set. It can be immediately clarified and replaced with normal roll paper before facsimile reception. Therefore, it is possible to prevent the received image information from being lost.

Further, the presence or absence of color formation on the recording paper heated during the paper cycle is detected by the color formation detecting means, and whether or not the normal roll paper is set in the recording paper judging section based on the signal detected by the color forming detection means. Since it is clarified whether the heat-sensitive roll paper has been set, the suitability of the set roll paper can be automatically determined before receiving the image information.

Further, when it is determined that the heat-sensitive roll paper is set, a warning is displayed or voiced to inform the operator, so that the operator can be sure that the roll paper has been set by mistake. -You can notify the server to prompt you to replace the roll paper.

Further, it is determined that the heat-sensitive roll paper is set, and all the image information received before the roll paper is replaced is accumulated and saved in the image memory, whereby the operator mistakenly operates. Even if the user does not notice that the thermal roll paper is set, it is possible to prevent the received image information from being lost.

Further, in the case of having a roll paper feeding unit and a standard paper feeding unit, when it is determined that the heat-sensitive roll paper is set, the roll paper feeding unit From the standard paper feed section to send out the standard paper, and by recording the received image information on the standard paper, it is possible to prevent the received image information from being lost and to immediately output the received image information. be able to.

Further, the received image information is output to the recording unit and stored in the image memory, and the image stored in the image memory is output when the operator who confirms the output recording paper issues an output instruction from the operation unit.
