Abstract

PURPOSE:To prevent an absence of picture information by inhibiting the enlargement of an original unless the size of reception-side recording paper is suitable even when a mode of original enlargement is selected. CONSTITUTION:When the enlargement mode is specified with an enlargement button 11, the interchanging of control information is started and the size signal 32 of recording paper set on a reception-side facsimile equipment is inputted to a comparing circuit 13. The comparing circuit 13 compares the size signal 31 of the original with the size signal 32 of the recording paper, and outputs an enlargement indication signal 33 when the size of the recording paper is larger than or equal to the size of picture information after the enlargement.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine that can enlarge and transmit a document.

[Prior art]

When the characters and figures written in the manuscript are small,
It would be convenient if the original could be enlarged and sent. There is a facsimile machine that can enlarge a document and send it in response to such a request. If you set a Δ4-size original in this facsimile machine and press the enlarge button, the original will be enlarged to a reduction ratio of, for example, 122%, and then transferred to the 84-size recording paper set in the receiver. The incident will be recorded.

However, in conventional facsimile machines, when an enlargement button placed on the operation panel is pressed, the image is enlarged in a uniform manner. Therefore, unless large-sized recording paper is set on the receiving side, a situation arises in which image information about the edges and edges of the document is not recorded.

[Purpose of the invention]

The present invention addresses these circumstances, and provides a facsimile machine that is capable of not enlarging an original when the size of recording paper on the receiving side is not suitable for enlarging even if a mode for enlarging the original is selected. Its purpose is to provide equipment.

[Structure of the invention]

The present invention includes a mode selection means for selecting an enlargement mode for enlarging a document at a predetermined magnification and sending it, and a chair discrimination device for determining the size relationship between the size of the document after enlargement and the size of recording paper on the receiving side. When the size of the original after enlargement is equal to or smaller than the size of the recording paper on the receiving side, the enlargement mode is selected. The facsimile apparatus is equipped with a control 111<.This prevents the document from being enlarged unconditionally and prevents image information from being omitted.

〔Example〕

The present invention will be explained in detail in the following examples. I will explain to you.

The drawing shows the main parts of a facsimile machine according to an embodiment of the present invention. An enlargement button 11 for enlarging a document is arranged on an operation panel (not shown) of this apparatus. When you press the enlarge button 11, the size change circuit 1 inside the device
The enable/full signal 14 is supplied to both the comparator circuit 13 and the comparator circuit 13, so that these circuits become operational.

This facsimile machine is equipped with two paper size detection means. One is a document size determination circuit 15, which determines the size of a document based on the movement position of a paper guide plate of a document setting tray (not shown). The determined document size information 16 is supplied to the size changing circuit 12.

The other one is a recording paper size determination circuit 17.

The recording paper size determination circuit 17 optically reads a bar code attached to a paper tube into which a long recording paper is attached to the right, and detects the width of the recording paper. The width information 18 is anime) 1
9, and is input to the transmission signal processing section 22 by the gate control signal 21 which becomes H (high) level in the reception mode.

The transmission signal processing unit 22 sends the recording paper width information 18 as part of the control information to the communication line 24 via the modem (variable iiL!) device 23. Furthermore, after adjusting the magnification of the image information 26 obtained from the reading section 25, the signal is compressed and redundancy is removed. Similarly, it is sent to the communication line 24 via the modem 23.

The circuit operation when the enlargement mode is specified in this facsimile machine will be described next.

When the operator presses the enlarge button 11, this device
An enlargement mode of 22% is specified. If a △4 size original is set in this facsimile machine, the size adjustment circuit 12 will be 3 as a result of enlarging the A4 size by 122%.
A 4-size size signal 31 is output. Such a size change circuit 12 may be a part of an arithmetic circuit, or may be a logic circuit that selects the size of the enlarged image information based on the relationship between the magnification and the document size. Further, when the enlargement ratio is constant, the document size information 16 can be regarded as size information after enlargement and used as is, and in this case, the size change circuit 12 can be practically omitted. The size signal 31 is input to the comparison circuit 13.

Now, when a line is established between this facsimile machine and the facsimile machine on the receiving side and the exchange of control information begins, the size signal 32 of the recording paper set in the facsimile machine on the receiving side is sent to the comparison circuit via the modem 23. 13 will be man-powered. The size signal 32 is a signal obtained by replacing the width information created by the facsimile machine on the receiving side with the size of the corresponding recording paper in the transmission signal processing ffR.

The comparison circuit 13 compares the size of the enlarged image information created on the sending side and the size of the recording paper on the receiving side based on the size signals 31 and 32. Then, the enlargement instruction signal 33 is output only when the size of the former is larger than or equal to that of the latter.

The enlargement instruction signal 33 is supplied to the transmission signal processing section 22 .

When the transmission signal processing unit 22 receives the enlargement instruction signal 33, it converts the image information supplied from the reading unit 25 into a magnification of 122.
% and supplies it to the modem 23. △4 on the sending side
If a size original is set, such enlargement processing is performed on the condition that recording paper capable of recording image information of 84 size or larger is set in the facsimile machine on the receiving side. If A4 size or 85 size recording paper is set on the receiving side, press the enlarge button 1.
Even though 1 was pressed, image information of the same size (Δ41'lJ) is transmitted.

It goes without saying that if the comparison circuit 13 can compare the sizes of the original and the recording paper in more detail, the transmission signal processing section 22 can also reduce the original to match the size of the recording paper and transmit it. Nor. In this case, the enlarge button 11 has the meaning of a designation button for matching the size of the transmitted image information with the size of the recording paper.

Note that in the facsimile machine of the embodiment described above, ',''
7 (Although a long recording paper was set on the H-i side, it is obvious that the present invention can be similarly applied to a facsimile machine using cut paper.

〔Effect of the invention〕

As described above, according to the present invention, even if the enlargement mode is always specified on the transmitting side, there is no risk of image information being lost on the receiving side. Therefore, there is no need to confirm the recording paper size on the receiving side in advance by telephone or the like, which contributes to increased office efficiency and reduces communication costs.
