Abstract

PURPOSE:To surely print out a received document data even when paper sheets of a paper feeding section run short by storing recording paper in an intermediate tray. CONSTITUTION:An MPU 1 uses a sensor 18 so as to check whether or not recording paper is in existence in an intermediate tray 14 and when no paper is stacked therein, a switch 16 is thrown to the position of a paper discharge section and a switch 17 is thrown to the position of the intermediate tray 14 to carry recording paper of a paper feeding section 12 to the intermediate tray 14. When paper is stacked in the paper feeding section 12 upon the receipt of a reception data, the switch 16 is thrown to the paper feeding section 12 and the switch 17 is thrown to the paper ejecting section 13, and when no paper is stacked in the paper feeding section 12, the switch 16 is thrown to the intermediate tray 14 and the switch 17 is thrown to the paper ejecting section 13 to ensure a document output after paper runs short and to interrupt succeeding communication. Thus, the succeeding document is stored with unreception and the loss of the reception data is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having an intermediate tray for double-sided printing.

[Prior Art] Conventionally, in a facsimile machine that outputs a received document to a printer while receiving document data from the other party's facsimile machine, when the reception of one page of the received document is completed, the printer for that page is output. It was supposed to start outputting to , and at the same time start receiving the next page.

[Problem M to be solved by the invention] However, in the above conventional example, if the recording paper to be printed is the last recording paper in the paper feed section, it is not possible to print the next page of the document that has already started receiving. However, there was a drawback that the received data was lost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can appropriately cope with a situation where a paper feed section runs out of recording paper without losing received data.

[Means for Solving the Problems] The present invention provides a facsimile machine that outputs a received document to a printer while receiving document data. If the paper runs out, the received document is output using the 1-record paper and the communication is interrupted.

[Function] In the present invention, by storing spare recording paper in the intermediate tray, even if the paper supply section runs out of recording paper, the recording paper in the intermediate tray can be used to ensure document output after the paper runs out. By interrupting subsequent communications, subsequent documents are retained as unreceived and loss of received data can be avoided.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention.

This facsimile machine includes an MPUI that controls the entire system, a receiving section 2 that receives image data, an image data memory 3 that stores the received image data, and a double-sided printer that outputs the image data onto recording paper. 4.

FIG. 2 is a block diagram showing a simplified configuration of the printer 4. As shown in FIG.

This printer 4 includes a printing section 11 that prints image signals sent from an external device onto recording paper, a paper feed section 12 that stores recording paper for feeding, and a discharge tray that stores recording paper after printing. A paper section 13, an intermediate tray 14 for storing spare recording paper, a paper ejection direction changeover switch 16 for switching the paper ejection direction to the paper ejection section 13 or the intermediate tray I4, and a paper ejection direction changeover switch 16 for switching the paper ejection direction to the paper ejection section 13 or the intermediate tray I4;
It has a paper feed direction 9J detection switch 17 for switching between the paper feeding direction 9J and the intermediate tray 14, and a sensor 18 for detecting the presence or absence of recording paper in the intermediate tray 14.

Further, numeral 15 in the figure indicates the position of a recording head that prints image data on paper.

Next, FIG. 3 is a flowchart illustrating the operation of such a facsimile machine at the time of reception.

First, when receiving an incoming call (S l), the MPU l detects whether there is recording paper in the intermediate tray 14 using the sensor 18.
(S2), and if there is no paper, turn the switch 16 to the paper discharge section side, switch the switch air to the intermediate tray 14 side, and transport the recording paper in the paper feed section 12 to the intermediate tray 14 (S2).
3.54).

At this time, if there is no paper in either the intermediate tray 14 or the paper feed section 12, the incoming call is rejected (55).

Next, when receiving data for one page is received (56
), if there is paper in the paper feed section 12 (37).

The switch 16 is switched to the paper feed section 12 side, and the switch 17 is switched to the paper discharge section 13 side, and the received document data is printed and reception of the next page is started (S8, S9).

When one page of received data is received, if there is no paper in the paper feed section 12 (S7), the switch 16 is switched to the intermediate tray 14 side, the switch 17 is switched to the paper ejection section 13 side, and the reception data is received. Print the document (S10)
, if the next page is received (S11), the reception is rejected (S12).

Note that if the reception is finished and all the received documents use the recording paper in the paper feed section 12, there will be some recording paper left in the intermediate tray 14, but the recording paper remaining in the intermediate tray 14 will be used for the next reception. It can be used as a backup recording paper for times or as a recording paper for reception result reports.

[Effects of the Invention] As explained above, according to the present invention, by accumulating recording paper in the intermediate tray, received document data can be reliably received even when the paper supply unit runs out of paper. There are effects that can be printed.

Claims (1)

[Claims] In a facsimile machine that outputs a received document to a printer while receiving document data, spare recording paper is accumulated in an intermediate tray at the time of an incoming call, and when the recording paper in the paper feed section runs out, A facsimile machine characterized in that it outputs a received document using the spare recording paper and interrupts communication.
