Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a redial transmission function for automatically dialing and transmitting to a destination transmitted in the past, and is particularly suitable for a compound copying machine having an image scaling function and a rotation function. Facsimile machine.

[0002]

2. Description of the Related Art Conventionally, as a facsimile apparatus having a redial transmission function, for example, Japanese Patent Application Laid-Open No. 4-341057.
As shown in the publication, history information including transmission destination information such as destination and line type, paper size, resolution, density, etc. is sequentially stored every time image data is transmitted, and the history information is sent to an operator from the history information at the time of redial transmission. A method of selecting desired history information has been proposed.

[0003]

However, in the above-mentioned conventional facsimile apparatus, only the transmission mode information such as the line type, the paper size of the transmission original, the resolution at the time of reading, the density, etc. is managed as the history information, and the destination is the other party. Since the receiving side information such as the size and direction of the recording paper of the receiver is not managed, the receiving side reduces or divides the received image according to the recording paper, and therefore an image different from the transmission original is output. However, there is a problem that an optimum received image cannot be obtained.

[0004] It should be noted that each time the transmitting operator makes a transmission,
The above problem can be solved by performing an operation according to the size and direction of the recording paper on the receiving side, but in this case, the operation becomes more troublesome. Also, after compressing and storing the transmitted document, decompress the compressed data so that it matches the direction of the recording paper of the recipient's receiver and that the transmitted document is recorded at the same size on the receiver side. If the data is reduced, rotated, compressed again, and transmitted, useless processing is performed.

In view of the above conventional problems, it is an object of the present invention to provide a facsimile apparatus capable of obtaining an optimum received image on the receiving side without performing a troublesome operation on the transmitting side during redial transmission.

[0006]

In order to achieve the above-mentioned object, the first means is to register the performance of the receiver of the destination in advance, the destination transmitted in the past, and the destination registered by the registering means. Storage means for correspondingly storing the performance of the receiver of the destination, and transmission means for image-processing the transmission document based on the performance of the receiver of the destination stored in the storage means at the time of redial transmission, and transmitting it to the destination. It is characterized by having.

In the second means, in the first means, the performance of the receiver of the destination is the size of the recording paper of the receiver, and in the transmitting means, the transmission original matches the size of the recording paper of the receiver. It is characterized by changing the magnification as follows.

In a third means, in the first or second means, the performance of the receiver of the destination is the direction of the recording paper of the receiver, and in the transmitting means, the transmission original is the direction of the recording paper of the receiver. It is characterized by rotating so as to match with.

A fourth means is characterized in that, in the second or third means, the transmitting means compresses and stores the transmitted original after scaling or rotating the transmitted original.

In a fifth means, in the first to fourth means, the storage means further stores a transmission method transmitted in the past, and the transmission means stores the past transmission stored in the storage means. It is characterized by transmitting by the method.

It is sent to D614.

Next, the processing during redial transmission will be described in detail with reference to FIG. First, the system controller 6
The RAM 651 on the 50 side is shown in FIG. 6 as redial data.
Facsimile transmission was performed in the past as shown in (1)
The destination, (2) transmission type, (3) reading condition, and (4) receiver output performance are stored. (1) As a destination, it is possible to input via the ten-key pad 402, or use a telephone number registered in a telephone directory or a group.

Further, (2) as transmission types, various types of direct transmission-closed connection-polling transmission-polling reception memory transmission-time designation-polling transmission-polling reception-closed transmission are stored. (3) As reading conditions, density, document size, character size, document type are stored,
The width of the recording paper is stored as the output performance of the receiver.

Then, the past transmission information stored in the RAM 651 and the output performance of the destination receiver are displayed on the LCD 401 as a list under the control of the operation unit controller 500 based on the instruction of the operator, and can be selected by the operator. Becomes When the operator selects a desired destination and presses the start key 404, the transmission original 607 is read by a scanner, the image data is subjected to various image processing under the control of the image processing controller 502, and black is displayed via the selector 612. The data DATA0 to DATA7 are accumulated in the image memory 620 in the main controller 501. Then, the compression / decompression device 622 compresses the compressed data to a designated compression code (MH, MR, MMR),
It is stored in the SAF memory 623 in the X controller 506.

In this case, the image stored in the image memory 620 is A4 size so that it matches the direction of the recording paper of the receiver of the other party, and the transmission original 607 is recorded in the receiver at the same size. When transmitting after 90 rotations such as landscape or B5 landscape, the rotator 621 before passing to the compression / expansion unit 622.
Then, after being rotated as shown in FIGS. 7 and 8, compression is performed by the compression / expansion device 622.

Therefore, after the transmission original is compressed and accumulated by such processing, the transmission original is recorded at the same magnification in the receiver side so as to match the direction of the recording paper of the receiver. Thus, there is no need to perform useless processing such as decompressing compressed data, rotating it, compressing it again, and transmitting it. Further, when transmitting the A3 original document to the B4 and A4 receivers, the compression process is performed after the reduction process as shown in FIGS.

The compressed data stored in the SAF memory 623 is transferred to the line buffer 624 in the G3 controller 507 during G3 transmission, recompressed by the compression / expansion unit 627 according to the mode of the receiving side, and modulated by the modem 625. , NCU (network control unit) 626 to the receiving side. Similarly, when sending G4,
The compressed data accumulated in the SAF memory 623 is transferred to the line buffer 628 in the G4 controller 508,
The data is recompressed by the compression / expansion unit 627 according to the mode on the receiving side and transmitted to the receiving side via the ISDN control unit 629 and the transformer 630.

At the time of FAX reception, the data sent from the transmission side through the line is NCU 626 (transformer 630), modem 625 (ISDN control unit 629), compression / expansion unit 62.
2 (compressor / decompressor 627) and line buffer 624 (line buffer 628) to store in the SAF memory 623. The compressed data stored in the SAF memory 623 is expanded by the compression / expansion unit 622 in the main controller 501 and expanded on the image memory 620.
In this case as well, if it is more efficient to transmit 90 rotations like A4 landscape and B5 landscape, the rotation is performed by the rotator 621. The data expanded on the image memory 620 is sent to the writing unit shown in FIG. 5 by the selector 612 and printing is performed.
