Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a facsimile device, and particularly to a facsimile device that uses light-fixing type heat-sensitive recording color that can record original images or manuscripts displayed using multiple colors. The present invention relates to an improvement in the recording speed of a facsimile device that performs multicolor recording.

[Conventional technology]

2. Description of the Related Art Facsimile apparatuses that display received facsimile signals in multiple colors using light-fixing thermosensitive recording paper that is sensitive to multiple colors have recently become well known.

The light-fixing type thermal recording paper used for this purpose takes into consideration the stability of the recorded image, and one that utilizes diazo coloring, which uses diazonium salt (hereinafter abbreviated as diazo) as a catalyst, has been put into practical use. ing. For example, in the case of two-color heat-sensitive recording of red and black, this diazo coloring uses two coloring materials A and B and diazo as a catalyst to first develop a red color by heat sensitivity, and then irradiates it with ultraviolet rays. Fixes with light. The diazo molecules are destroyed by this ultraviolet irradiation and the catalytic effect is lost. In this state, by further heating the recording paper, a black color develops. It is normally provided to the user in this state. In this final color development state, so-called photofixing is usually not necessary. this is,
This is because, in the final color development state, the color development state is set to remain stable unless it is heated in the vicinity of a flaming heat source or is heated to a fairly high temperature such as by ignition.

FIG. 2 is a side view showing the main recording part of a conventional facsimile apparatus using multi-color light-fixing type thermal recording paper, taking as an example the case where the plural colors are two colors, red and black.

When recording facsimile reception signals, the recording paper 2 stored in the roll 1 is conveyed in the direction of arrow A by the rotation of the platen roller 4 while being held between the head 3 and the platen roller 4. The platen roller 4 is rotated by a motor 9 coupled via a coupling mechanism 401. The head 3 is fixed to the case via a spring and prints on the recording paper 2 while pressing it against the platen roller 4 with a predetermined pressure. This printing is performed based on a facsimile reception signal supplied from a receiving section (not shown) of the facsimile device to the printing section of the head 3. In the printing section, heating elements for thermal recording are arranged in a line perpendicular to the transport direction A for each pixel corresponding to one scanning line in the horizontal direction on the recording paper 2.

The print by the head 3 is first recorded as a first color, for example, red, and then is subjected to an optical fixing process by the fixing unit 6 via the cutter 5.

The fixing unit 6 performs optical fixation using ultraviolet light for printing and printing on the recording paper 2 being conveyed, and is equipped with one or more fluorescent lamps 61.
and a reflecting plate 6. By this fixing device unit 6, the recording paper 2 is optically fixed and scanned one after another for each recording line, and when the optical fixation for a predetermined processing unit, for example, one page of JIS paper size A4 is completed, the first color is fixed. The amount of conveyance of the recording paper 2 required for printing is rewound in the direction of arrow B by the reverse rotation of the platen roller 4, and then the amount of conveyance of the recording paper 2 required for printing the second color is
For example, it is thermally recorded in black. In this heat-sensitive recording, the optically fixed first color is maintained in a state unrelated to this printing. Note that the facsimile reception signal is transmitted and received in a signal format compatible with such color-based printing.

Now, the recording paper 2 on which this second color printing was performed
Similarly to the first color, the recording paper 2 is again conveyed in the direction of the arrow A, and then the recording paper 2 is cut by the cutter 5 one page at a time and outputted via the discharge rollers 7 and 8.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional facsimile apparatus of this type has the following problems.

That is, there is a considerable difference between the optical fixing speed and the printing speed, and the degree of difference differs for each recording color. Therefore, it is possible to process these multiple color records at one unified paper feed speed, or to create a final record that is colored in such a way as to ensure practical stability against optical stimulation, without the need for additional optical fixing. Conventional recording methods that process even colors based on this uniform paper feed speed have the drawback of unnecessarily increasing processing time.

It is an object of the present invention to eliminate the above-mentioned drawbacks, and to provide a facsimile machine using a light-fixing type thermal recording paper capable of recording a plurality of n colors. To provide a facsimile device that significantly improves recording speed by recording at a paper feed speed that corresponds to the lower speed of printing speed and printing speed, and recording only the final color at a paper feed speed that corresponds to the printing speed. It's about doing.

[Means for solving problems]

The apparatus of the present invention provides a facsimile apparatus using light-fixing thermal recording paper capable of recording n colors, in which light of each color from the first color to the (n-1)th color of the light-fixing thermal recording paper is used. The fixing type thermal recording is executed at a paper feed speed corresponding to the lower speed of the optical fixing speed and printing speed, which are different from each other, and only the final nth color is executed at a paper feed speed corresponding to the printing speed. The present invention has a configuration including a plurality of color recording means that speeds up recording by ensuring optical fixation and printing reliability for each recording color.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the main recording part of a facsimile apparatus of the present invention using multi-color light-fixing type thermal recording paper.

An embodiment of the recording main parts shown in FIG. 1 includes a roll 1, recording paper 2, bed 3, platen roller 4, cutter 5, fuser unit 6', discharge roller 7,
8, a motor 9, a drive control section 10, and the like.

In this example, it is assumed that the first to (n-1)th colors are recorded at a paper feed speed that matches the lower of the light fixing speed and printing speed for each color. Fuser unit 6'
corresponds to (n-1) recorded colors.
Fluorescent lamps 61' are arranged almost in a line so as to be adjacent to each other, and each emits fluorescent light of a wavelength corresponding to the recorded color to be fixed each time a fixing process is performed.

In such a configuration, the reliability of the optical fixing operation and the printing operation depend on the time it takes for the recording paper 2 to pass through the irradiation field formed by the fixing unit 6', that is, the paper feed speed of the recording paper 2. Furthermore, the printing operation can be ensured depending on the time during which the recording paper 2 receives the printing action by the head 3, that is, the paper feeding speed of the recording paper 2. In this embodiment, among the different combinations of light fixing and reliable printing times corresponding to the differences in wavelength for each color, the lower speed is set for each color. The paper feed speed is set to be quick and efficient, increasing reliability and ensuring both reliability and speed of recording. Note that for the n-th color only, normally, as described above, there is no need to perform additional optical fixing, so the paper feeding speed is set depending only on the printing speed.

The fluorescent lamp 61' of the fixing unit 6' is blinked under the control of a blinking control signal supplied from the drive control section 10.

Under the control of a built-in program, the drive control section 10 supplies drive control signals to the head 3 and motor 9 in addition to the above-mentioned blinking control signal, and drives the platen roller 4 via the motor 9 and the coupling mechanism 401. , the recording paper 2 is transported in the direction of arrow A at a paper feeding speed that ensures reliable optical fixing and printing by selecting the lower speed of the optical fixing speed and printing speed, which are different for each recording color. Fix with light. After optical fixing, the recording paper 2 is rewound in the direction of arrow B by the amount of conveyance, and printing and optical fixing for the next recording color are performed. In this way, the recording paper is repeatedly printed and optically fixed for up to (n-1) colors, and in the case of the final nth color, it usually has stable light resistance without additional optical fixing, as described above. After printing, the paper is cut by the cutter 5 and outputted from the discharge rollers 7 and 8. In this way, the motor 9 is driven to set the paper feed speed of the recording paper for each recording color, and the drive control is performed to control the head 3 to operate in response to the switching of the paper feed speed. It is carried out under the control of 10. In this way, the processing time can be significantly reduced by setting fine-grained paper feed speeds for each recording color and shortening the recording time for the final recording color.

〔Effect of the invention〕

As explained above, according to the present invention, in a facsimile apparatus that uses light-fixing thermal recording paper of multiple colors, the light fixing speed and printing speed for each recording color are determined from the first color to the (n-1)th color. A facsimile machine that can significantly reduce recording time is equipped with a means to record at a paper feed speed that corresponds to the low speed of , and a paper feed speed that corresponds to the printing speed for the final recorded color. It has the effect of being achievable.
