The control unit is a CPU which is a micro combinator.
122, video signal processing control, lamp driver 121 for exposure and scanning, switching motor driver 115, digitizer 116, and operation panel 120 are controlled by signals $l 508 (bus), 503, 504, respectively.

Reference numeral 505 denotes a signal line for serial communication which is commonly used and is inputted by the operator from the digitizer 116 according to a protocol between the CPU 122 and the digitizer 116. That is, 505 is a signal line for inputting coordinates, area instructions, copy mode instructions, magnification ratio instructions, etc. when editing the original, for example, moving or compositing.

Further, Sll and S21 are sensors for detecting the position of the original exposure scanning unit (111 in FIG. 1), and the home position is detected in Sll, and the white level correction of the image signal is performed at this location. . In S21, it is detected that there is a document exposure scanning unit at the leading edge of the image, and this position becomes the reference position of the document.

Signals ITOP, BD, VCLK, VI in FIG.
DEOlHSYNC, SRCOM (511-516
) are interface signals between the color printer section 102 and the scanner section 101 in FIG. 1, respectively.

Image signal VIDEO51 read by scanner unit lot
4 are all sent to the color printer section 102 based on the above signals. ITOP is a synchronization signal in the image forwarding direction (sub-scanning direction), and is executed once for sending out one screen, that is, once for each of the four colors (yellow, magenta, cyan, black), for a total of four times. This occurs in color printer section 1.
When the leading edge of the transfer paper wound on the transfer drum 716 of No. 02 receives a toner image transferred at the contact point with the photosensitive drum 715, the transfer drum 716 and the photosensitive drum 716 are rotated so that the position matches the image of the leading edge of the document.

This is a main scanning direction synchronization signal generated in synchronization with BD
Strictly speaking, the VIDEO signal 514 is H.
It is sent out in synchronization with 3YNC515. This is because the BD signal 515 is generated in synchronization with the rotation of the polygon mirror, so there is a lot of jitter in the motor that rotates the polygon mirror 712. This is because H3YNC515, which is generated in synchronization with VCLK which is originally free of jitter, is required.SRCOM is a signal line for half-duplex bidirectional serial communication, and it All instructions, such as color mode, cassette selection, and printer section status information 1, such as jam, paper out, weight, etc., are exchanged via this communication line SRCOM.

The operation of this embodiment will be described below with reference to the drawings.

Let us assume that the diagram shown in FIG. 2(a) is the manuscript to be transmitted. The part surrounded by the frame 21 in Fig. 2(a) is
The case where the output position is changed and the data is transmitted as shown in FIG. 2(b) will be explained. First, the original shown in FIG. 2(a) is read from the reading section 34, and image data is captured into the memory 33. Next, use the operation unit 32 to specify the area 21 to be transmitted on the display unit 38 with a cursor or the like,
Next, the output position on the output paper on the receiving side of this image data is set by specifying the address of the position of the output start point 23 in FIG. 2(b). After receiving this operation,
The main control unit 31 calculates which part of the image data stored in the memory 33 is to be transmitted.

As an example, the number of pixels in the main scanning direction of area 21 in FIG. 2(a), that is, the X size shown by 24 in FIG. 2(b), is 5.
00 pixels, the number of pixels in the sub-scanning direction, that is, Fig. 2(b)
Assume that the y size shown by 25 is 1000 pixels. In addition, the address on the paper of the output start point 23 in FIG. 2(b) is x=1
00. Let y=75. Furthermore, it is assumed that the current transmission data format is full color, RGB, 8 bits each, and uncompressed. These pieces of information are sent as additional information to the image data to be sent to the other party's system in accordance with the format shown in FIG. 3 before the image data is sent. Third
In the figure, 10 is the position information of the point (point 23 in the example of FIG. 2(b)) at which image data output starts on the output paper on the receiving side;
Reference numeral 1 indicates size information representing the size of the area of the image data to be output, and reference numeral 12 indicates color mode information for identifying attributes of the image data to be transmitted. Furthermore, if the color mode information codes in this embodiment are defined as shown in the table shown in FIG. 4, in the case of this embodiment, the information transmitted prior to the image information will be as shown in FIG. The information is generated by the main control unit 31.

Next, communication control will be explained.

In communication control, first, after transmitting a communication control protocol to the destination system specified by the operation unit 32,
A command is issued to clear the memory on the receiving side, and then the additional information is transmitted. After that, the image data to be transmitted is transmitted, and the transmission is completed.

Finally, the operation of the receiving system will be explained.

After executing the memory clear request received from the transmitting side, the system on the receiving side writes the image data that was subsequently transferred to the memory 33 on the receiving side based on the additional information, and outputs the information written in the memory. By outputting from the unit 35 onto recording paper, an output image shown in FIG. 2(b) can be obtained.

Although the present embodiment has been described as transmitting and outputting one image, it is possible to synthesize a plurality of images by repeating area determination and transmission. Furthermore, when compositing multiple images, the format of the image data to be transferred does not have to be one type, as can be easily inferred.Furthermore, the color mode information table shown in Figure 4 is not limited to this table; It can be easily inferred that by changing the converter 36, it becomes possible to transmit various image data formats.

Next, a method for editing and outputting received image data in the receiving side system will be described.

To simplify the explanation, consider enlargement processing as an editing function. In the receiving system, the received image data is the image data shown in FIG. 2(b), and it is assumed that the image data has already been stored in the memory within the receiving system. In addition, the magnification ratio is set to "2" in both the 7 is a block diagram of the data conversion unit in this embodiment, which can calculate the address in the memory 33 of the position. In the figure, 70.75 indicates the x and y of the output start address, respectively. This is an initial value register that stores a value. Further, 72 and 73 are increment registers for storing the reciprocals of the enlargement ratios in the X direction and
Store. The adders 76 and 77 each input an initial value register 7 according to the respective synchronization signals 79 and 7100.
With the value of 0.75 as the initial value, the X register 71. It operates to add the value stored in the increment register 72.73 to the value in the y register 74 as an increment value, output it to 7110 as an address signal, and write the result to each register 71.74.

In the case of this embodiment, 100 is set in the X initial value register 70, 75 is set in the Y initial value register 75, and the
2. When both the X increment register 73 is set to 0.5, the X register 71 becomes r 100, 100.5, 1
01.0...'' and the Y register 74 is r75
．． 0.75.5, 76.0...'' and inputs the X register 71. Based on the address output from the Y register 74, the memory 33 is accessed, the corresponding image data is taken into the data converter 78, and is outputted to the output unit 35 through the bus 7130. By repeating this for X and Y pixels indicated by the size information in the additional information, enlarged image data can be obtained. By starting to capture the image data from the output start position specified by the transmitting side and performing the capture for the number of pixels specified by the transmitting side, only the useful image data specified by the transmitting side is enlarged and output to the output section 35. Ru. Also, at this time,
The output start position on the output paper may be specified by the receiving side using an address, or may be set by displaying it on the display unit 38 and moving it one display. An example of outputting an enlarged image is shown in FIG. Shown below.

If there is no additional information such as position information, it can be easily inferred that the CPU or the like may scan the memory 33 from the beginning and calculate the address where the image data starts.

Next, an explanation will be given of the operation when there is an auxiliary storage device which can store image data for several sheets in addition to the memory 33 as shown in FIG.

As mentioned above, when sending part or all of a document from the sending side to the receiving side, the memory 33 on the receiving side can only store image data for one page of originals, so it is necessary to clear the memory on the receiving side before sending. It is necessary to do this. If it is desired to save the data currently in the memory 33, the image data currently stored in the memory is saved to the auxiliary storage device before clearing the memory. This evacuation method will be explained below.

The data structure of the auxiliary storage device 80 is shown in FIG. 11, in which the header information 90 includes the following transfer information, additional information,
This is an information field for managing address information and size information in the auxiliary storage device 80 of the image data group. Transfer information 95 is a field that holds information on the sending side for identifying the sending side, such as the time of transfer, company name, and telephone number. Further, 92.94 is a field that holds image data, and 91.93 is a field 92, respectively.
．． This field stores additional information added from the sending side when the image data held in 94 is transferred. Information on these fields is created by the seed control unit 31 and saved from the memory 33 to the auxiliary storage device 80.

Furthermore, if the capacity of the auxiliary storage device becomes insufficient, the time information of each data in the transfer information field is referred to, and the oldest data is erased in order, and new data is saved in its place.

An operation in which the operator on the receiving side calls up and reuses the image data saved in the auxiliary storage device 80 in this way will be explained.

The operator uses the operation unit 32 to retrieve desired image data from the auxiliary storage device. At this time, the display section 38 displays a transfer information field as shown in FIG. , by pointing to the relevant item with a cursor, etc.
In order to read the image data selected by this operation into the memory, the main control unit 31 calls it from the auxiliary storage device 80 according to the data structure shown in FIG. The data is created, edited if necessary, and then output to the output unit 35.

It is also possible to delete the corresponding image data from the auxiliary storage device 80 or send it to another image processing system.

Furthermore, when the image data is saved in the auxiliary storage device 80, the image data may be compressed and stored, and then expanded and restored when it is recalled to the memory 33.

Furthermore, if the capacity of the auxiliary storage device 80 is large, the entire image data for one memory sheet may be saved instead of the image data that is part of the document sent from the sending side.

In addition, the main control unit 31 is provided with means for monitoring the state of the communication control unit 37, and when a new “incoming call” is detected while the main control unit 31 is “communicating”, the transmission or reception is stopped using the memory 33. If there is a further transmission (or request for transmission) while the data is being transmitted, the main control unit 31 receives the data and directly stores it in the auxiliary storage device 80. Even if a message is being sent, new messages can be received.

[Effects of the Invention] As explained above, by providing an auxiliary storage device, received data can be stored for a long period of time.

This has the effect of allowing multiple pieces of received data to be stored.

Furthermore, while receiving or transmitting information, it is possible to receive other information in parallel.
