CONSTITUTION:In the case of printing out reception information, a recording paper size is designated by a recording paper setting key provided to a function key 24 and a desired reception size is designated by using a ten-key or the like in advance to apply automatic magnification processing magnifying or reducing the picture to the recording paper size and print-out is implemented. On the other hand, when it is discriminated that the user has not set a reception exclusive size, a CPU 4 decides the size of the recording paper. At first, when recording of the same size as the received original is available, the size is used and when the recording of the same size is not available, the recording size at which least magnification is required is selected and a picture output is obtained through automatic magnification.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, and more particularly to an image processing apparatus for recording and outputting input image data.

[0002]

2. Description of the Related Art Conventionally, copying machines, facsimile machines, laser beam printers, etc. have been known as image processing apparatuses for recording and outputting image data.

In a facsimile machine, when a recording paper of the same size as that of the transmitting side is loaded, the same size recording output is performed, and when there is no recording paper of the same size, especially from the transmitting side. Also, the received image is recorded by performing scaling in the reduction direction only when the size of the recording paper is small. When the recording paper size on the receiving side is large, the scaling is not performed, and the recording output is performed using the partial size of the recording paper without changing the size.

[0004]

In the above conventional structure, it is unavoidable that reduction is performed when the recording paper size is smaller than the original on the transmission side, but in the opposite case, that is, the recording paper size is smaller. It is a waste of the recording paper that the same image as the transmission original is recorded in its original size in a large size only on a part of it, and if you want an image of the transmission original enlarged to the size of the recording paper, It was necessary to perform troublesome operations such as enlarging and copying.

An object of the present invention is to solve the above problems and to provide an image processing apparatus capable of obtaining an image output of a size desired by a user without requiring a troublesome operation.

[0006]

In order to solve the above problems, in the present invention, in an image processing apparatus for recording and outputting input image data, a means for designating an image output size and an input image A configuration is adopted which has a control means for performing necessary scaling on the data and performing recording output at the image output size designated by the designating means.

[0007]

According to the above configuration, by specifying the image output size, it is possible to perform the scaling and then output the image with that size.

The communication operation is controlled by the CPU 4 composed of a microprocessor or the like. The control program of the CPU 4 is stored in the ROM 5. Further, image data to be transmitted / received and telephone number data necessary for automatic dial processing described later are stored in the RAM 6.

The received image data is recorded and output to the recording unit 7 including a thermal printer or a laser beam printer. Further, the recording unit 7 can be loaded with at least one type of recording paper, preferably several types of recording paper at the same time, and can set a recording paper of a dedicated size used for facsimile reception as described later.

The original image to be transmitted is read by the reading unit 8 which is composed of a CCD line sensor, an original conveying system and the like. Power supply power required for the operation of each part of the device is supplied from a power supply part 9. In the figure, the reference numeral 10 is a power switch.

Further, the CPU 4 is connected to an operation panel 11 including input keys and a display for controlling the communication operation. The operation panel 11 is configured as shown in FIG. As shown in FIG. 2, the operation panel 1
A display 25 including various input keys and a liquid crystal panel is arranged on the operation surface of 1.

The operation keys are a ten-key pad 21 for manually inputting a telephone number, time data, etc., a start key 22 for starting transmission / reception operation, copy operation, etc., and a stop key 2 for instructing cancellation of input data or interruption of operation.
3, a function key 24 for selecting various communication functions, and a one-touch key 26 for abbreviated input of a telephone number. 24 one-touch keys 26
Are identified by the alphabets "AX".

Further, in the present embodiment, when recording and outputting the reception information, the recording paper size is designated by the recording paper setting key 24a provided in the function key 24, and the desired reception dedicated recording paper size is set in advance by the ten keys or the like. By doing so, the recording output can be performed through the automatic scaling process for reducing or enlarging the image to a size suitable for the recording paper size.

Next, the control procedure of the CPU 4 at the time of reception will be described with reference to the flowchart of FIG. The procedure shown is
Of the reception control, only the determination of the recording paper size and the image scaling processing are shown.

In step S31, the recording paper setting key 24
It is determined whether or not the reception-only size setting operation using a is performed, and if the setting operation is performed, the recording paper size designated in step S33 is stored.

When step S31 is denied, it is determined in step S32 whether or not facsimile reception is being performed. Facsimile reception is automatically started in response to a manual operation or a call signal input from the line 1 as in a known procedure.

When performing the receiving operation, step S34
Then, in step S33, it is determined whether or not the recording paper size dedicated to reception is stored.

In step S34, if the user has set the receive-only size, the process proceeds to step S35, and the received image data is scaled (enlarged or reduced) to the receive-only size specified by the user. , Step S
Record output at 37.

On the other hand, if it is determined in step S34 that the user has not designated the receive-only size, the size of the recording paper to be recorded and output is determined in step S36.
Here, the size of the recording paper is determined in the following priority order.

1) If there is a recording paper of the same size as the received original, that recording paper is used.

2) If there is no recording paper of the same size as the original,
Select the recording paper size that requires the least magnification.

When the recording paper size is determined in step S36, the process proceeds to step S35, and the received original image is automatically scaled (enlarged or reduced) so as to have the recording paper size determined in step S36 and an image is output. To do.

By determining the size for exclusive use of reception by the above control, when recording and outputting the received image, the recording paper of that size is always used and the automatically received original image is automatically scaled and output. can do. By this, for example, by loading A4 recording paper and selecting this size as the reception-only size, when receiving a B5 image, B5 recording is performed on a part of the A4 recording paper as in the conventional case. It is possible to enlarge and record to A4 instead of performing.

Further, even if the reception-only size is not set, and further, if there is no recording paper of the same size as the original image, recording output can be performed using recording paper of a size having the smallest possible scaling factor.

When only one type of recording paper is loaded in the recording unit 7, the original image is used as the recording paper for which the original image is used in the automatic scaling in step S35, regardless of the control in steps S34 and S36. It is conceivable to enlarge or reduce the size and print out.

FIG. 4 shows a modification of the control shown in FIG.
In FIG. 4, step S36 is replaced by step S36 '(note that steps with the same reference numerals perform the same processing as in FIG. 3). Step S36 '
Then, the recording paper size for recording output is determined in the following priority order.

1) If there is the same size as the received document size, that recording paper is used.

2) When carrying out scaling, select a recording paper size that allows scaling on the enlargement side.

3) If the enlargement-side recording paper size cannot be used, select the recording paper size with the smallest possible magnification.

According to the embodiment shown in FIG. 4, when the reception-only size is not set and there is no recording paper of the received document size, it is possible to control so that the enlargement-side scaling is performed as much as possible. For this reason, the recording area of the loaded recording paper can be used as effectively (widely) as possible to perform the recording output, the recording paper area is not wasted as in the conventional case, and the trouble such as enlargement copying is not caused. There is an advantage that various operations are unnecessary.

As described above, it is possible to provide an excellent facsimile apparatus capable of recording and outputting a manuscript which is easy for the user to read as much as possible without requiring the troublesome work of copying the output image as in the conventional case.

Although the facsimile apparatus has been exemplified above,
Of course, the present invention can be applied to a copying machine, a laser beam printer, or the like.
