Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly, to a facsimile machine capable of setting a plurality of roll-shaped recording papers.

[Conventional technology]

With the spread of facsimile apparatuses, facsimile apparatuses capable of setting a plurality of roll-shaped recording papers have appeared, and a plurality of roll-shaped recording papers having the same width size can be set, or roll-shaped recording papers having different width sizes can be set. By setting a plurality of, the replacement period of the rolled recording paper can be extended,
In order to avoid a reception disabled state due to a recording paper shortage, a roll recording paper having an appropriate width size according to the size of a received document is fed to a recording unit for recording.

That is, in a facsimile apparatus capable of setting a plurality of roll-shaped recording papers, when a plurality of roll-shaped recording papers having different width sizes are set, a roll-shaped recording paper having a width suitable for the size of the received document is selected. The image is fed between the thermal head and the platen roller, and the received image information is recorded by the thermal head while being conveyed by the feed roller.

Further, when roll-shaped recording paper having the same width size is set, the conventional facsimile apparatus can be classified into two types according to the method of transporting the roll-shaped recording paper.
In the first transport method, a plurality of roll-shaped recording papers having the same width size are sequentially exchanged, for example, every time one message is recorded, and are fed between the thermal head and the platen roller. This is a method of sequentially recording on paper. In the second transport method, a plurality of roll-shaped recording papers having the same width size are preferentially used with a preset roll-shaped recording paper. This is a method of preferentially using the set roll-shaped recording paper.

In the facsimile apparatus, when such recording on the roll-shaped recording paper is performed, the roll-shaped recording paper is cut into a predetermined length by a cutter and discharged onto a recording paper tray attached to the facsimile apparatus.

[Problems to be solved by the invention]

However, in such a conventional facsimile apparatus, when roll-shaped recording papers having the same width size are set, a plurality of roll-shaped recording papers having the same width size are sequentially used or set in advance. Because the rolled recording paper that has been used is given priority, the image information is recorded and the recording paper that has been discharged onto the recording paper tray is poorly placed. There are problems such as the occurrence of paper jam and the problem that the recording quality is degraded.

That is, when a plurality of roll-shaped recording papers are used in order, the number of the roll-shaped recording papers decreases almost at the same time. A large number of recording papers with a risk of curling will be discharged onto the recording paper tray, and the placement of the recording papers will be degraded. As a result, the recording paper may fall from the recording paper tray, complicating the work of arranging the recording paper, causing a jam of the recording paper, and worsening all the roll-shaped recording paper at a time. There is a problem that the reception may be disabled.

In addition, when a plurality of recording papers on a roll are preferentially used from a preset recording paper, if the rolled recording paper at the roll position to be used preferentially is exhausted and replaced, the replaced new recording paper is replaced. Roll-type recording paper is also used preferentially, and roll-type recording paper set at another roll position is not used for a long period of time. In the case of paper, the color changes or the coloring performance deteriorates under the influence of temperature, humidity, ultraviolet rays, and the like. As a result, the mounting property on the recording paper tray deteriorates,
There is a problem that the recording paper may fall from the recording paper tray, a recording paper jam may occur, and the image quality is deteriorated.

[Object of the invention]

In view of this, the present invention provides a method of recording a plurality of roll-shaped recording papers having the same width size when recording the image information. By preferentially feeding the recording paper between the thermal head and the platen roller and recording, it prevents curling of the rolled recording paper and improves the ease of placement on the recording paper tray In addition to preventing the recording paper from deteriorating and preventing the recording paper from dropping from the recording paper tray and the occurrence of recording paper jam, the management work of the recording paper is made simple and easy, It aims to improve quality.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a recording thermal head which is capable of setting a plurality of roll-shaped recording papers having different width sizes, has a plurality of heating elements, and performs recording on the roll-shaped recording paper; And a plurality of feed rollers arranged for each roll-shaped recording paper and feeding each roll-shaped recording paper between the thermal head and the platen roller. And a pair of feed roller pairs are appropriately selected and driven, so that one of the plurality of roll-shaped recording sheets is fed between the thermal head and the platen roller. In a facsimile apparatus for feeding and recording on the fed rolled recording paper, a recording paper presence / absence detecting means for detecting an end mark of the recording paper; Recording paper replacement state detecting means for detecting whether the recording paper has been replaced and set after detecting the end mark of the roll-shaped recording paper, and detecting the width size of the recording paper when the recording paper has been set; According to the detection results of the recording paper presence / absence detecting means and the recording paper exchange state detecting means, when a plurality of roll-shaped recording papers having the same width size are set, the setting time of one set recording paper is changed to the other set recording time. Judge whether it is before or after the paper setting time.When recording the image information, the thermal head with priority is given to the roll paper that has been set first, out of the set roll paper of the same width. And a platen roller.

The thermal head 21 is provided with a plurality of thermal elements in the axial direction of the platen roller 22, that is, in the width direction of the roll-shaped recording paper 30, 31, and the thermal head 21
It is urged toward the platen roller 22 by a spring or the like (not shown). In the thermal head 21, the thermal elements generate heat based on the image information, and the heat records the image information on the roll-shaped recording paper 30 or the roll-shaped recording paper 31. The platen roller 22 is rotationally driven by a motor (not shown),
The rolled recording papers 30 and 31 are transported. Feed roller pair 23
Feeds one roll-shaped recording paper 30 between the thermal head 21 and the platen roller 22, and feed roller pair 24 feeds the other roll-shaped recording paper 31 between the thermal head 21 and the platen roller 22. I do. The roll-shaped recording paper 30 and the roll-shaped recording paper 31 may have different width sizes (for example, A4 size width and B4 size width), or may have the same width size. May be set.

The auto cutter 29 cuts the roll-shaped recording paper 30 or the roll-shaped recording paper 31 on which an image is recorded by the thermal head 21 for each page.

Referring again to FIG. 1, the operation display unit 10 includes various operation keys such as a numeric keypad and a start key, and also includes a display (for example, a liquid crystal display). The displayed contents and various information transmitted from the facsimile machine 1 to the operator are displayed on a display.

 Next, the operation will be described.

The present invention is characterized in that when a plurality of roll-shaped recording papers having the same width size are set, the older roll-shaped recording paper is automatically conveyed to a platen roller. Hereinafter, the recording paper selection processing will be described with reference to the flowchart of FIG.

When the facsimile machine 1 is powered on and the rolled recording papers 30 and 31 of the same width are set (step
T1 and T2), an initial operation is performed, and a reception standby state is set (step T3). In this initial operation, one of the roll-shaped recording papers 30 and 31 having the same width size is selected, and
By driving the feed roller 23 or the feed roller 24,
The roll-shaped recording paper 30 or the roll-shaped recording paper 31 is fed between the thermal head 21 and the platen roller 22 to be in a reception standby state. In the initial operation, the user can select which of the roll-shaped recording paper 30 and the roll-shaped recording paper 31 is to be set by a key operation of the operation display unit 10, or the facsimile machine 1
May be set in advance.

Thereafter, the facsimile machine 1 checks at every predetermined timing whether or not the end mark of the rolled recording paper 30, 31 has been detected based on the signal from the recording paper presence sensor 25, 26 (steps T4, T5). Roll of recording paper
If the end marks 30 and 31 have not been detected, a process of recognizing the selected state of the rolled recording papers 30 and 31 selected by the initial process is performed (step T6). When the recognition process of the selected state of the roll-shaped recording papers 30 and 31 is performed, the end mark of the roll-shaped recording paper 30 or the roll-shaped recording paper 31 is also determined at a predetermined timing by a signal from the recording paper presence / absence sensor 25 or 26. Check if detected (step T4,
T5) When the end mark of the roll-shaped recording paper 30 is detected, it is checked whether the case of the facsimile machine 1 has been opened (step T7). The case of the facsimile machine 1 can be opened for exchanging the rolled recording papers 30 and 31. Usually, the facsimile machine 1 is provided with a sensor for detecting the opening and closing of the case for safety management. Have been. Therefore, in the present invention, it is checked whether or not the case has been opened based on a signal from a sensor for detecting opening and closing of the case. If the case has not been opened, it is checked whether the end mark of the roll-shaped recording paper 31 has been detected (step T8). If the end mark of the roll-shaped recording paper 31 has not been detected, the roll-shaped recording paper 30 Although the paper cannot be used because it is out of paper, the roll-shaped recording paper 31 is judged to be usable and
A selection process of 31 is performed (step T9). The process of selecting the roll-shaped recording paper 31 can be performed, for example, by setting a flag indicating that the roll-shaped recording paper 31 has been selected, but is not limited to this method. When the process of selecting the roll-shaped recording paper 31 is completed, the process returns to step T6 to perform a recognition process of the selected state, that is, the fact that the roll-shaped recording paper 31 has been selected. This selection state recognition processing is, for example, processing in which the CPU 5 recognizes the state of the flag set in the selection processing.

In step T8, when the end mark is also detected for the roll-shaped recording paper 31 and it is not detected that the replacement of the roll-shaped recording paper 31 has been performed, a selection process of no roll-shaped recording paper is performed. At the same time, processing for running out of roll-shaped recording paper is performed (step T10). That is, the process of selecting no roll-shaped recording paper is a process of selecting that there is no roll-shaped recording paper to be preferentially fed between the thermal head 21 and the platen roller 22. When the selection process of “None” is completed, the process proceeds to step T6 as described above.
Then, the recognition processing for the absence of the roll-shaped recording paper is performed. The roll-shaped recording paper cut-out process is a process of displaying on the display of the operation display unit 10 that the roll-shaped recording paper has run out, notifying the operator, and performing a process of disabling reception.

On the other hand, if it is detected in step T7 that the case has been opened, then after waiting for detecting that the case has been closed (step T11), it is determined whether or not the rolled recording paper 30 has been set by the recording paper width sensor 27. (Step T12). When the roll-shaped recording paper 30 is detected, it is checked whether or not the roll-shaped recording paper 31 having the same width is set based on a signal from the recording-paper width sensor 28 (step T13). Roll paper 31 rather than roll paper 30
Is the old roll-shaped recording paper.
After performing the selection process of step 31 (step T14), step T6
Then, the selection is recognized. Step T13
When the roll-shaped recording paper 31 is not detected, it is recognized that the roll-shaped recording paper having the same width is not set, and
The selection processing of the rolled recording paper 30 that has just been set is performed (step T15), and the recognition processing of the selection result is performed in step T6.

When the roll-shaped recording paper 30 is not detected in Step T12, it is determined that the replacement of the roll-shaped recording paper 30 has not been performed, and it is checked whether the roll-shaped recording paper 31 is set (Step T16). Roll recording paper 31
When is set, the roll-shaped recording paper 31 is selected (step T17). When the roll-shaped recording paper 31 is not set, the selection processing for the absence of the roll-shaped recording paper is performed, and (Step T18). When these selection processes are completed, the process returns to step T6 to perform a process of recognizing the selection result.

When the end mark of the roll-shaped recording paper 31 is detected in steps T4 and T5, it is checked whether the case has been opened (step T19). If the case has not been opened, the roll-shaped recording paper 31 is replaced. However, it is determined that the roll recording paper 30 having the same width is only the roll recording paper 30, and the selection processing of the roll recording paper 30 is performed (step
T20). When the process of selecting the roll-shaped recording paper 30 is completed, the flow returns to step T6 to select the roll-shaped recording paper 30.
A recognition process is performed to the effect that is selected.

In step T19, if it is detected that the case has been opened, then after waiting for detecting that the case has been closed (step T21), it is determined whether or not the roll-shaped recording paper 31 has been set by the recording paper width sensor 28. Check by signal (step T22). When the roll-shaped recording paper 31 is detected, it is checked whether or not the roll-shaped recording paper 30 having the same width is set based on a signal from the recording-paper width sensor 27 (step T23). It is determined that the roll-shaped recording paper 30 is an older roll-shaped recording paper than the roll-shaped recording paper 31, and the roll-shaped recording paper 30 is selected (step T24).
Returning to step 6, the selection is recognized. Step T23
When the roll-shaped recording paper 30 is not detected, it is recognized that the roll-shaped recording paper of the same width has been removed and is not set, and the currently set roll-shaped recording paper 31 is selected (step T25). ), A recognition process of the selection result is performed in step T6. That is, when a document of the document width is received, the roll-shaped recording paper 31 is moved to the thermal head.
A process of feeding between the platen roller 21 and the platen roller 22 is performed.

In step T22, when the roll-shaped recording paper 31 is not detected, the case is opened and closed,
It is determined that the replacement of 31 has not been performed, and it is checked whether the roll-shaped recording paper 30 has been set (step T26). When the roll-shaped recording paper 30 is set, the roll-shaped recording paper 30 is selected (step
T27) When the roll-shaped recording paper 30 is not set, a process of selecting no roll-shaped recording paper is performed, and a process of running out of the roll-shaped recording paper is performed (step T28). When these selection processes are completed, the process returns to step T6 to perform a process of recognizing the selection result.

As described above, based on the detection results of the recording paper width sensors 27 and 28, it is checked whether a plurality of roll recording papers 30 and 31 having the same width are set, and a plurality of roll recording papers 30 and 31 having the same width are set. Sometimes, the recording paper presence sensor 25,
Based on the detection result of 26, it is possible to determine the old rolled recording paper 30, 31 and set the old rolled recording paper 30, 31 preferentially between the thermal head 21 and the platen roller 22. it can. Therefore, as in the prior art, a plurality of roll-shaped recording papers having the same width are sequentially exchanged and recorded each time a received document is recorded, and the plurality of roll-shaped recording papers are lost at one time.
A large number of roll-shaped recording papers that are in a reception-disabled state or have a risk of curling are placed on a recording paper tray in a large amount, so that it is possible to troubleshoot recording paper arrangement work and prevent the occurrence of recording paper jams. . Further, as in the prior art, only the preset roll-shaped recording paper of a plurality of roll-shaped recording papers having the same width is preferentially used, and the roll-shaped recording paper that is not used forever is set in the facsimile apparatus. In this state, it is possible to prevent the curling of the recording paper due to curling, to prevent the recording paper from jamming, and to prevent the deterioration of the recording quality due to the deterioration in the case of the heat-sensitive recording paper. be able to. As a result, it is possible to improve the reception efficiency, simplify and easily arrange the recording paper, and prevent the occurrence of the recording paper jam. Further, the recording quality in the case of heat-sensitive recording paper can be improved.

In the above embodiment, the case where two roll-shaped recording papers having the same width are set has been described. However, the present invention is not limited to this, and the case where a plurality of roll-shaped recording papers having the same width are set is described. Can be similarly applied.
