Abstract

PURPOSE:To prevent the omission of image information to be transmitted by deciding a variable magnification by means of a variable magnification deciding means based on an image reading size inputted by means of a size input key and a recording paper size to be recognized. CONSTITUTION:A CPU 5 as the variable magnification deciding means decides the variable magnification based on the image reading size inputted by an image reading size input key 22 and the recording paper size inputted by a transmitting/recording size input key 21. Namely, at the time of transmission, for example, the recording paper size at a receiving side is recognized by a communication protocol. An optimum magnifying and reducing rate (variable magnification) is decided by the CPU 5 based on the image reading size and recording paper size, the reading is executed by the variable magnification to be decided, respectively, and the recording and transmission are executed based on read data.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image transmitting device.

[Conventional technology]

2. Description of the Related Art Conventionally, image transmitting apparatuses, such as facsimile machines, have been provided with a constant magnification key or variable magnification key on an operation panel, and in addition, in cases where a recording paper size can be selected, a recording paper selection key has been provided.

In addition, devices that read images by passing through sheet-like originals (hereinafter referred to as sheet originals) are equipped with a slider to align the sheet original, and the image is read from the set position of this slider. I was able to see the width of the original manuscript.

(Similar points to be solved by the invention) Conventional image transmitting devices, such as facsimile machines, are configured to key in the recording paper size and magnification ratio, so depending on the combination of the two, a predetermined range of the document may be missing. There was a problem that it was not recorded.

Furthermore, in conventional image forming apparatuses, for example, those that read images by passing a sheet document through the sheet, the width of the document on which the image is to be read is uniquely determined by the setting position of the slider.

Even if a predetermined range of a sheet document is scaled to the same size or enlarged or reduced, the predetermined range of the document may be missing.

The present invention was made in order to solve the above-mentioned problems, and it is an object of the present invention to provide an image transmitting device that prevents a predetermined range of a document from being omitted on recording paper.

(Means for Solving the Interference Point) The image transmitting device according to the present invention includes a size input key for inputting the reading size of one image, means for recognizing the recording paper size on the receiving side, and the image reading size and the recording paper size. A variable magnification determining means is provided for determining a variable magnification based on the following.

(Operation) In the image transmitting apparatus according to the present invention, the magnification ratio determining means determines the magnification ratio based on the image reading size input using the size input key and the recognized recording paper size.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention. In the figure, 1 is an operation panel, and a keyboard 2 shown in FIG.
and a display 3 corresponding to the keyboard 2.

The keyboard 2 includes a transmission/recording size input key 21 for inputting the recording paper size, an image reading size input key 22 for manually inputting the image reading size, and a copy density key 2.
3, an AE key 24, and a magnification key 25.

The display device 3 includes a cassette size display group 31 that lights up in response to the input of the transmission/recording size input key 21, and an image reading size display group 31 that lights up in response to the input of the image reading size input key 22. A display group 32, a copy density display 33 that displays the density selected by the copy density key 23, an AE display 34 that lights up when the AE key is pressed, and a magnification change key 25 that is pressed. It is composed of a variable magnification display 35 that lights up correspondingly.

In FIG. 1, 5 is a CPU as a variable magnification determining means.
(central processing unit
), the image reading size input using the image reading size input key 22 and the sending/recording size input key 21
The magnification ratio is determined based on the input recording paper size. Reference numeral 6 represents a transmission control unit for FAX and the like. F is a recording unit that records an image of the determined magnification ratio on recording paper of the transmission/recording size manually input by the key. Reference numeral 8 denotes a reading unit that reads an image according to the image reading size entered manually by a key.

Next, the operation will be explained based on the flowchart shown in FIG.

When image reading starts, the CPU determines whether the image reading size has been specified (S-1), and as a result of the judgment, if the image reading size has not been specified,
The reading size is determined by the default size, document guide, document size sensor, etc. (S-2)
, the corresponding image reading size indicator lights up (S
-3). Note that since steps S-1 to S-3 are determined before starting reading, the display may be changed after starting.

Next, it is determined whether it is copying or transmission 5-4), and as a result of the judgment, in the case of copying, for example, the width of the recording paper cassette or roll paper is detected 5-S), and in the case of transmission, for example, the recording paper on the receiving side is detected. The paper size is recognized by the communication protocol (S-6).

Then, based on the image reading size and the recording paper size, the CPU 5 determines the optimum enlargement/reduction ratio (variable magnification ratio) (S-7), and according to the determined enlargement, same size, or reduction (S-a), Reading (S-9), same-size reading (S-10), and reduced reading (S-11) are performed, and recording and transmission are performed based on the read data (S-12).

Table 1 shows the output sizes obtained in this way.

Table 1 If the default is determined in step S-2, the display of the transmission/recording size is the size of the recording paper set in the printer, for example, A4, and the display of the image reading size display group 32 is The display is a sheet. Further, the display on the variable magnification display 35 is the same size.

At this time, if the display on the image reading size display group 32 is, for example, B4, the display on the variable magnification display 35 is from B4 to A.
4 is displayed, and automatic reduction reading of 81% is performed.

Further, at this time, if the scaling key 25 is pressed to set the reduction, for example from A3 to A4, the image reading size display group 32 displays A3.

Here, when the image is read as a sheet and the image read size display group 32 is displayed as a sheet, press the send/record size key 21 to send/record size display group 3
When the display of 1 is set to 84, if the slider position is A4, the display on the variable magnification display 35 changes from A4 to B4, and enlarged reading is performed.

Also, if the slider position is 84 and the display on the transmission/recording size display group is A4, the display on the variable magnification display 35 is B.
4→A4, but at this time, if the same size is selected using the variable size key 25, the A4 range is output on a B4 original.

Next, the recording paper has multiple sizes, for example, A4, B4, and A3.
If it is possible to select from among the three sizes, the appropriate recording paper size is automatically selected by setting the image reading size and magnification ratio, and the selected recording paper is displayed on the transmission/recording size display group 31. Is displayed. For example, if the image reading size is 84 and B4→A4 is selected using the scaling key 25, the display on the transmission/recording size display group will be A4.

Copying has been described above, but in the case of transmission, the first priority is to detect the recording paper size of the destination machine, and when the operator specifies the continuation size, the magnification ratio is automatically determined.

(Effects of the Invention) As explained above, according to the present invention, it is possible to prevent the loss of transmitted image information.
