FIG. 4 is a block diagram showing the circuit configuration of the control section of the copying apparatus shown in FIG.

Reference numeral 201 corresponds to a CCD shown in the second diagram, which converts an original image set on the original platen 3 into an electrical signal and outputs it as an image signal. An image processing circuit 202 performs image processing on the image signal from the CCD 201, such as shading correction for correcting non-uniformity of output and γ correction for correcting density characteristics. 207 is an add-on display RAM that stores code data such as characters and symbols to be added on; 208 is an add-on font ROM that outputs dot data representing characters corresponding to the code data; and 205 stores dot data from the add-on font ROM 208. The add-on RAM 206 controls the output of the dot data stored in the add-on RAM, and outputs the add-on start signal ADST.
An add-on image generation circuit 203 generates add-on image data to be inserted into the original image in response to the image processing circuit 202, and 203 is a combination of the original image data from the image processing circuit 202 and the add-on image generation circuit 2.
Synthesis circuit for synthesizing add-on image data from 06, 2
04 is a printer that performs printing operations based on image data from the composition circuit 203.

Further, 210 is a control unit CPU that controls the operation of each block of the reader, and according to the program stored in the ROM 21.4, the RAM 2]5. Control operation is performed using l10216 etc.

Reference numeral 213 denotes an editor provided on the document platen pressure plate 142;
Reference numeral 12 corresponds to the operation unit shown in the third figure, reference numeral 211 is a buzzer that emits a buzzer sound to the operator, and reference numeral 209 is a sub-scanning counter that counts the number of recording lines of the printer.

With the above configuration, the original image (A,
), it becomes possible to print out the image (B) or (C) with information such as characters and symbols of a desired size inserted at the desired position.

FIG. 7 shows the control procedure of the CPU 210 regarding input of address characters.

Hereinafter, a method for setting each mote using an editor and an operation section will be explained using FIG. 7.

When the character input key 134 on the editor is pressed (Sll
), the screen shown in FIG. 5(A) is displayed on the liquid crystal display section 123 (S13). In the figure, a cursor 501 is blinking at the display position where characters are input, and is controlled to move vertically and horizontally by pressing the four displayed cursor movement keys 502.

The operator can correct the error by moving the cursor 501 to the incorrectly inputted character and inputting the character again.

Furthermore, when the displayed clear key 503 is pressed, all characters are cleared.

Now, a method for inputting characters using the editor 213 will be described below.

Editor 213 and CPU 2 ], O is performing serial communication, and point pen 138 is communicating with editor 21
3) Tells the CPU 210 whether the second position is pointed to. When the operator points to a certain position on the editor 213 with the point pen 138, the CPU 2]0 determines whether the point coordinate information from the editor 213 is within the character input surface 143 (S]4). When the point position is within the character input surface 143, a buzzer 3 is used to notify the operator that characters have been input.
9 is beeping (515), and the code corresponding to each character, specifically "A" → 0"B" → 1...
A blank space 149 is determined and stored in the add-on display RAM 207 (S16). Then, the characters corresponding to the code data stored in the add-on display RAM 207 are reflected on the screen display, and the cursor is usually advanced one position to the right.

Also, if the current cursor position is on the right side,
-Move the cursor to the far left side of the knife. In this way, the characters to be combined with the image are input, and the liquid crystal display section 1
23 shows the display shown in FIG. 5(B).

Figure 6 shows an add-on display R corresponding to the display in Figure 5 (B).
The contents of AM207 are shown.

The character string input in this way will be displayed in the add-on display RAM 20.
7, it is merely stored as a coat and has no character as image information.

When the start key 7 instructs the start of the image forming operation, the CPU 210 first displays the add-on display RAM 2.
The font information corresponding to the code O7 is read from the add-on font ROM 208 and expanded into the add-on RAM 205. At this time, the add-on RAM 205 only displays the font information of the input characters in order.
Even if the add-on RAM 205 is directly read, image information is not obtained. Therefore, CPU21. O is the number of characters in the horizontal direction and the number of characters in the vertical direction for the add-on image generation circuit 206;
Parameters such as the number of font constituent dots and character size are set, and when the add-on RAM 205 is read out through the add-on image generation circuit 206, image information is generated.

After developing the font information in the add-on RAM 205 and setting parameters in the add-on image generation circuit 206, the CPU 210 reads the original by moving the optical system of the reader in the sub-scanning direction, performs photoelectric conversion using the CCD 201, and sends the image to the image processing circuit. 202 performs image processing such as shape ink correction and γ correction, and synthesizes character string image data from the add-on image generation circuit 206 and original image data into a synthesis circuit 203
are combined and output to the printer 204.

As a result, the image shown in FIG. 8 (and the original image 801 shown in FIG.
Recorded material 80 in which the character information displayed in B) is synthesized
2.

Next, the zoom mode will be explained. When the zoom mode key 129 is pressed, the screen shown in FIG. 9(B) is displayed, and press the X down key 902.
X auto key 903. X up key 904. Y down key 905. Y auto key 906° Y up key 907. XY down key 908. XY auto key 90J
Set the magnification using the XY up keys 9]0.

In the display of FIG. 9(A), the coordinate input screen for the editor 213-! 41 zoom scale point pen 13
8, the CPU 2 ] 0 is controlled to convert the coordinate data to a magnification corresponding to the zoom scale, change the screen to that shown in FIG. 9(B), and display the input magnification.

Next, the area designation mote will be explained. Up to 3 rectangular areas can be entered, and the area specification key 130
When you press , if the area corresponding to the area number (1, 2, or 3) is set, the 9th
Figure (C), or if it is not set, Figure 9 (D)
) is displayed. In FIG. 9(C), 912 is an area clear key for clearing the currently displayed area; 91
3 is the area up key to increase the area number, 914
Similarly, 915 is an area down key, and 915 is an area number display that displays the current area number.

When the area up key 913 is pressed in the figure, if an area is registered, area number 9 in Figure 9(C) is displayed.
15 becomes 2', and the mote of trimming or masking and the area corresponding to the setting value are displayed on the left side of the liquid crystal display section 123. If no area is registered, the area number "2" in FIG. 9(D) will be displayed. Also, Figure 9 (C)
And in FIG. 9(D), touch panel input oyster-91
When 6 is pressed, the screen shown in FIG. 9 (F) is displayed, and the control is such that the point position of the input area can be corrected in units of mm and a new area can be registered on the liquid crystal display section 123. 9th
In Figure (D), if you enter one point on the diagonal input of the area, the screen changes to the one shown in Figure 9 (E), and the remaining
When the OK main key 17 is pressed after inputting the point, a new area is registered and the screen shown in FIG. 9(C) appears.

Next, the movement mode will be explained. When the movement key 1.31 is pressed, the screen shown in FIG. 9(G) appears on the liquid crystal display section 123.
will be displayed.

The operator selects and presses one of the center movement key 918, corner movement key 919, designated movement key 920, and binding margin key 921. When the selected key is for corner movement, specified movement, or binding margin, FIG. 9(H), FIG. 9(1), and FIG. 9(■()) are displayed, respectively.

In Fig. 9 (I()), the type of corner movement can be specified, and in Fig. 9 (+), the destination of the specified movement can be specified in the editor 213-
] - or by pressing the touch panel input key -916, the display shown in Fig. 9 (J) is displayed, and the editor 21
3. It is possible to modify the points specified above or make new inputs. In FIG. 9(K), it is possible to set the amount of movement in the binding mode.

Next, the page snapshot mode will be explained. , when the page continuous copying key 132 is pressed, FIG. 9(L) is displayed. In the figure, for example, the left and right page quick copy mode is a mode that outputs the left half and right half of the scanned document on separate sheets,
The left page quick copy mode is a mode in which only the left half of the scanned document is output. In addition to these modes, right, up and down, '2', and down modes can be set.

Next, the enlarged continuous shooting mode will be explained. Enlarged continuous copying mode is a mode in which when copying at a set magnification, if the output paper does not fit, it is output on multiple sheets separately, and by combining the multiple output sheets, a single output result is obtained. It will be done. To set this mode, press the enlarged continuous shooting key 133, and the screen shown in FIG. 9(M) will be displayed, and the mode setting will be made.

As explained above, six independent modes can be set by using the editor 213, liquid crystal display 123, etc., but conversely, the operator can separate the desired copy output result into each mode and set each mode individually. mode must be set independently.

Therefore, it is possible to set a combination mode that is often used by the operator, thereby improving operability for the operator.

However, when setting such a combination mode, if a new key is added, it may become confused with the six mote keys that can be set independently, and the operability may worsen.

Furthermore, a key must be added as a new mode in the /S-code manner, and work such as modifying the circuit or adding keys is required to make multiple such composite modes function. Therefore, in the present embodiment, the mode is set using the character input screen 143 of the editor 213 used in the character entry camo-1.

The following is a specific example of a composite mode: AZ, which is a composite of the area, zoom, and movement modes of the six modes mentioned above.
About S-mote Document area 301 in Figure 10 (A)
Let us consider the operation of changing the magnification and moving the image to the area 302 in FIG. 10 (It). First, if there is no composite mode, specify area A in area specification mode, and select YC/YO in zoom mode.

The magnification in the X and Y directions is determined by XC/XO, and the output paper, area B, Xs, and Ys values must be specified in the specified movement mode as described above, and the mode key must be pressed three times in total. did not become.

However, in order to realize this mode, XI + "l + X2+ "2+ X3+ shown in Figure 1O is required.
``If you have 3+X4+Y4 data, you can determine the designated area, destination, and magnification.

This will be explained in detail below using FIG. 11 and FIG. 12. FIG. 11 shows the display state of the liquid crystal display section +23 when the composite mode is designated, and FIG. 12 shows the operating procedure of the CPU 210 when the composite mode is designated.

When specifying the composite mode, the operator first presses the asterisk key 102 in FIG. 3 (S100).

Due to this operation, the character string input from the character input surface 14.3 becomes a mode input. Here, when AZS is entered on the character input surface 143 using the point pen 138, (81,
01), and FIG. 11(A) is displayed (S102). If there is a point input with the point pen 138 (S10
3), Display FIG. 11 (B) (Sl, 04) L/, After inputting another diagonal point (S105), press the OK key 401 (S107), Xl+ x2. in the document area.
y It Y2 data input is completed.

Next, display FIG. 11(C) (3108) and specify the output canister position. In the same figure, if a point is input (S109), the screen shown in FIG. 11 (D) is displayed (
Solo). So after inputting another diagonal point (Sell
), press the OK key 401 (S113), and the output area X3. x4. Y3. Since Y4 is determined, calculate the X7 magnification, set the input canily, and set the movement data (Sl
14).

In this manner, various parameters in the composite mode are set, and then the operator presses the start key to perform the image forming operation. Although the example uses the character input surface on the editor used in the character input mode, the character input method is not limited to using the editor, and the 17-I of the keyboard CRT etc.
A character input device based on configuration is also conceivable.

Further, although the composite mode setting has been given as an example, applications such as displaying the machine version, service mode data, self-diagnosis function display, etc. are also possible according to the character string input from the character input screen 143. .

〔effect〕

As described above, new mode settings can be made without adding keys or circuits, and operability can be improved.
