[0002]

2. Description of the Related Art Usually, a facsimile machine sets a fax paper in a paper feed cassette, automatically feeds the paper to a printing section when a fax is received, and prints the paper based on the transmitted image data. Is printed on one side. However, in recent years, a facsimile apparatus having a double-sided printing function in order to improve economy has been disclosed in, for example, Japanese Patent Laid-Open No.
No. 0-294815.

According to this apparatus, the one-sided printing function of recording the received originals only on the front surface of the recording paper, and the odd number of the received originals is recorded on the front surface of the recording paper and the even number is recorded on the rear surface of the recording paper. The double-sided printing function configures an image recording unit that records and outputs the received original image on recording paper.By selecting this double-sided printing function, the number of recording paper sheets can be reduced by half. Therefore, a very suitable facsimile apparatus which can improve the economical efficiency has been proposed.

[0004]

However, in the facsimile machine disclosed in Japanese Patent Laid-Open No. 10-294815, when double-sided printing is effective as a printing method at the time of reception, the recording paper that can be set in the facsimile machine is Naturally, both sides are limited to unused paper. Although this publication does not explicitly provide two paper feed cassettes, one for both sides and one for one side, for example, these two cassettes are provided and If both papers are unused paper and one paper feed cassette is unused paper on only one side, the double-sided printing function itself must be disabled.

Further, this device is capable of selectively switching between double-sided printing and single-sided printing, but the double-sided printing function is enabled although no particular reference is made to the case where the paper runs out during reception. If you run out of paper in, the first few sheets will be printed on both sides, and the rest will be printed on one side.As a result, you cannot tell at a glance how much double-sided printing is and what side is single-sided printing. It will bother you.

In view of the above, the present invention is capable of further improving the convenience without causing any trouble even if a new double-sided sheet is lost in a state in which the double-sided printing function of the facsimile apparatus having the double-sided printing function is enabled. It is an object to provide a fulfilled facsimile machine.

A facsimile apparatus characterized in that it is configured to have notification information for notifying that printing has been performed on only one side.

According to the above invention, upon reception, the facsimile machine expands the image data in the page memory and prints it out. At this time, when the image data is a plurality of pages, double-sided printing is performed on the odd page on the front side and the even page on the back side. If the paper for double-sided printing (unused paper on both sides) runs out during reception, the paper for single-sided printing (the back side is already printed) is fed and single-sided printing is performed. When performing one-sided printing, a mark that can be recognized as such is added to a part of the paper, for example, the upper right corner so that the user can easily determine that the printing is “one-sided printing”.

According to a third aspect of the present invention, in the first aspect, the predetermined information is received information printed on only one unused side of the sheet based on the restarted image data, and the print information on the back side of the sheet. And a second annunciation information for announcing that is invalid.

A fourth aspect of the present invention is the facsimile apparatus according to the third aspect, wherein the second notification information is printed on the back surface of the paper.

According to the above invention, upon reception, the facsimile machine expands the image data in the page memory and prints it out. At this time, when the image data is a plurality of pages, double-sided printing is performed on the odd page on the front side and the even page on the back side. If the paper for double-sided printing (unused paper on both sides) runs out during reception, feed the paper for single-sided printing (the back side is already printed) and print the received image on the front side. On the back surface (which has already been printed before), a mark indicating that the printed image is invalid is printed, and the keyword is printed over the printed image.

According to a fifth aspect of the present invention, in the first aspect, the predetermined information is third notification information having a sentence notifying that the double-sided printing has been interrupted due to a paper shortage for double-sided printing. There is a facsimile machine.

To do.

The modem 12 connected to the NCU 121 is
Data is transmitted and received via an NCU (network control unit). Also, although not shown,
The facsimile machine according to the present embodiment is provided with a double-sided paper feed cassette for setting new fax paper not used on both sides and a single-sided paper feed cassette for setting unused fax paper on only one side. The structure is a structure in which only one conventional paper feeding cassette is simply provided in two stages, and the mechanical characteristics thereof are not particularly limited in the present invention as seen in the copying apparatus, and therefore detailed description will be omitted.

Next, the operation when the double-sided printing function of the facsimile apparatus of the present embodiment configured as described above is enabled will be described based on the flowchart of FIG. First, the facsimile apparatus connected to the communication network via the modem 12 determines whether the plotter 81 is in an operable state when receiving a fax (step S1), and when it is determined to be operable (step S1: Yes). Determines whether or not there is a next page of the received image data (step S2). At this time, if the received image data has only one page, or if there is image data of a plurality of pages and the image data ends with an odd number of sheets, the process proceeds to step S6, and if not, the process proceeds to step S3.

First, when the description is given for the case where there are a plurality of pages of image data (in the case of an even number of sheets: 4 pages), there is always a second page after the first page in step S2 (step S2). : Yes), it is determined whether there is a new fax paper that is not used on both sides in a double-sided paper feed cassette through a sensor (not shown) (step S3), and it is determined that there is a new fax paper. In this case, the paper is transferred to the plotter 81, double-sided printing is performed based on the image data of the first page and the second page, and then the paper is transferred to the discharge unit and discharged.

Next, the next page of the image data, that is, 3
It is determined whether there is a page (step S5). Three
If it is determined that there is a page (step S5: Ye
s), and further determines whether there is a fourth page (step S
2) If it is determined that there is (step S2: Ye
s) In the same manner as described above, it is determined whether or not there is new fax paper that is not used on both sides in the double-sided paper feed cassette (step S3). Based on this, the plotter 81 performs double-sided printing (step S4). Then, it is determined whether there is the fifth page (step S5), and if there is, the same steps as described above are performed, and if not (step S5: No), the process ends.

To exemplify the case where the image data is an odd number of pages of 3 pages, in step 2, the next page of 3 pages, 4
It is determined that there is no page (step S2: No),
A sensor (not shown) is used to determine whether or not one-sided unused fax paper (or copy paper, etc.) is in the one-sided paper feed cassette (step S6). If it is determined that there is (step S6: Yes), the sheet is transferred to the plotter 81, double-sided printing is performed based on the image data of the third page, and at the same time, a mark for notifying that it is single-sided printing is printed ( In step S7), the sheet is transferred to the discharge section and discharged, and the processing is ended. However, for safety, in step 5, the existence of the next page is confirmed, and then the processing is ended.

Further, in step 3, when it is determined that there is no new fax paper for both sides unused in the double-sided paper feed cassette, a message indicating that the double-sided paper is out of paper is displayed on the display unit such as a liquid crystal panel. At the same time, the process proceeds to step 6, and it is determined whether there is unused fax paper on only one side in the single-sided paper feeding cassette. If yes, the process proceeds to step 7 and the plotter 81 based on the image data.
Performs double-sided printing, and at the same time, prints a mark notifying that it is single-sided printing. If it is determined that there is no unused fax paper on only one side, a message indicating that the one-sided paper is out of paper is displayed on the display unit consisting of a liquid crystal panel, etc., and the image data is stored in the SAF 5 and waits. At the same time, the processing is restarted.

When the single-sided printing function is enabled,
Paper is fed and printed only from the single-sided paper feed cassette, but in this case, naturally, if you set unused fax paper on both sides in the cassette, the back side will be blank. The printed fax paper is printed and output.

As another mode, as shown in the flow chart of FIG. 3, with the double-sided printing function enabled,
When the process proceeds to step 6, it is determined whether or not there is unused fax paper on only one side in the single-sided sheet feeding cassette (step S6: Yes).
On the front surface, which is an unused surface, based on the image data (step S8), and subsequently (or at the same time), on the back surface, which is the used surface, a mark indicating that the image information written on this surface is invalid. May be printed (step S9).

Further, as another mode, as shown in the flow chart of FIG. 4, in the case where the double-sided printing function is enabled and the process proceeds to step 6, the single-sided printing is performed with the double-sided printing function enabled. If it is determined that there is unused fax paper on only one side in the paper feed cassette of No. 2 (step S6: Yes), the fact that there is no unused fax paper on both sides and printing has been interrupted Printing may be performed on the surface which is an unused surface (step S10).

[0028]

As described above, the present invention has the following advantageous effects. According to the present invention, even when double-sided printing and single-sided printing are mixed, the user can easily determine the double-sided printing paper and the single-sided printing paper. Also, when the fact that the double-sided printing is interrupted is printed on the surface that is an unused surface, it prevents mixture of double-sided printing and single-sided printing in advance.
If the user desires, a facsimile apparatus capable of outputting mixedly and improving immediacy can be provided.
