[0007]

According to the present invention, the paper size and the paper data area are converted into coordinate data, and the positional relationship between the paper size and the paper data area is made to correlate and then enlarged. -Since the reduction is calculated, the data area position after the enlargement / reduction can be changed by calculation.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram of an embodiment of a copying apparatus according to the present invention.

The copying apparatus reads the size of a document placed on a document table and a data area (hereinafter also referred to as document coordinate data) such as characters in the document and converts the read data into coordinate data. An original reading unit 1 for outputting, a storage unit 2 for storing the original coordinate data output from the original reading unit 1, an original coordinate data is read out from the storage unit 2 and displayed, and an enlarged / reduced size of the original and after copying Data area (hereinafter also referred to as copy coordinate data) of the monitor unit 3 having a function of inputting coordinate data from the outside, copy coordinate data input to the monitor unit 3 and document coordinate data read from the storage unit 2. From the calculation unit 4 that calculates the copy data based on the calculation unit, the control unit 5 that controls the copy unit based on the calculation result of the calculation unit 4, and the copy unit 6 that performs the copy according to the instruction from the control unit 5. That.

The document reading unit 1 sets the document size to, for example,
A size detection function of converting to an electric signal by an optical / electrical conversion means such as a phototransistor, and a scanner function of converting data such as characters printed on a document into a light / dark electric signal and detecting the same. And a coordinate data conversion function for converting the detection signal into coordinate data.

The storage unit 2 is a writable and readable memory such as a RAM.

FIG. 2 is a schematic explanatory view showing the structure of the monitor unit 3. The monitor unit 3 has coordinates A (X axis) and coordinates B (Y
(Axis) data is displayed on the display 11 and a touch input section 12 provided on the surface of the display 11 and having a transparent film-shaped coordinate data input section. When designated by a touch pen or the like, the coordinate data is input to the monitor unit 3.

The monitor unit 3 has a start button 13,
Message area 14, numeric keypad 15, magnification display section 16
Having.

The calculation unit 4 calculates copy data based on the copy coordinate data input to the monitor unit 3 and the document coordinate data read from the storage unit 2. That is, first, the coordinate P1 of the original size and the coordinates P2, P of the enlargement / reduction size
The enlargement / reduction ratio is calculated from 3, and then the character data after copying is determined from the positional relationship between the original paper and the data such as characters in the original (the positional relationship between the coordinates P1 of the original size and the coordinates P4 of the original data area). Calculate the position of. As will be described later, the position of data such as characters after copying can be changed by a fingertip or the like.

The controller 5 controls the enlargement / calculation calculated by the calculator 4.
The copying unit 6 is controlled based on the reduction ratio and the position data of the data such as characters after copying.

The copying unit 6 copies the data such as characters to the designated position on the paper at the enlargement / reduction ratio designated by the instruction from the control unit 5.

Next, the operation of the copying apparatus will be described with reference to FIG. 3 together with FIGS. FIG. 3 is a schematic diagram showing a display on the display 11 at the time of enlargement.

First, when a user places a document on a document table, the document size and data area are read by the document reading unit 1, and the read data is the coordinate P1 of the document size.
And the storage unit 2 after being converted into the coordinates P4 of the data area
(S1).

Next, the monitor unit 3 reads out the coordinates P1 and P4 stored in the storage unit 2 and displays them on the display 11 (S2). Area 2 indicated by coordinate P1 in FIGS. 2 and 3.
Reference numeral 1 indicates the original size, and the area 22 indicated by the coordinate P4.
Indicates a data area in the original.

Next, the user inputs a desired size for enlargement / reduction into the touch input section 12 of the display 11 with a fingertip. Now, a case will be described where the document size is A4 landscape and the document size is enlarged to A3 landscape.

The user inputs the coordinate P2 indicating the A3 horizontal direction into the touch input section 12 with a fingertip or the like. If you mistakenly say A4 sideways and A
If the middle coordinate P10 of 3 horizontal lines is input, the monitor unit 3 displays a message in the message area 14 to confirm whether the input size is A4 horizontal or A3 horizontal, and inputs it to the user. Urge you to start over.

When the coordinate P2 is input to the touch input unit 12, the monitor unit 3 sends the coordinate P2 to the calculation unit 4 (S3). Then, the calculation unit 4 reads the coordinate P1 of the document size from the storage unit 2 (S4), calculates the enlargement magnification from the coordinate P1 and the coordinate P2 previously input from the monitor unit 3, and the magnification is displayed in the magnification display unit 16 To display. At the same time as this display, the enlarged paper size 23 and the data area 24 are displayed (S5).

In this case, the calculation section 4 calculates the coordinate P5 so that the data area 24 is located substantially at the center of the paper size 23, and the result is displayed on the display 11.
Therefore, even when data such as characters is not printed in the center of the document, the data such as characters can be copied to the center of the sheet at the time of enlargement.

Next, the monitor unit 3 sends a confirmation message for changing the position of the data area to the message area 1 of the monitor unit 3.
4 is displayed.

When the user looking at this display desires to change the position of the data area, he / she inputs the changed position of the data area to the touch input section 12 with his / her fingertip or the like. For example, when the coordinate P6 slightly lower left than the coordinate P5 is designated, the data of the coordinate P6 is sent to the calculation unit 4, and the calculation unit 4 calculates the change of the data area position. Then, as a result of the calculation, the data area 25 of the coordinate P6 is displayed on the display 11 instead of the data area 24.

As a result, the user can move the position of the expanded data area to an arbitrary position. However, the program in the monitor unit 3 is configured so as not to accept the designation that the data area 25 extends beyond the paper size 23.

Next, the calculation unit 4 sends the calculation result data of the magnification and the data position to the control unit 5 (S6). After confirming that the user presses the start button 13, the control unit 5 sends control data for the paper size 23 and the data area position 24 or 25 after copying to the copying unit 6, and the copying unit 6
To execute copying (S7).

Next, the case of reducing the document size from A4 horizontal to A4 vertical will be described. In this case, in S3, instead of the coordinate P2, the coordinate P3 indicating the A4 vertical document size is input with a fingertip or the like (see FIG. 2). The subsequent operation procedure is the same as in the case of expansion.

Further, in the case of copying the original size, the monitor unit 3 inputs an enlargement / reduction from the user within a fixed time (S
After confirming that 3) does not exist, a confirmation message for full-scale copying is displayed in the message area 14. Then, if there is no input (S3) of enlargement / reduction from this display by the user, the monitor unit 3 causes the calculation unit 4 to calculate the actual size copy, and the control unit 5 causes the copy unit 6 to perform the actual size copy. Let it be done.

On the other hand, when the enlargement / reduction input (S3) is performed, copying is performed by the same procedure as S4 to S7 described above.

[0031]

According to the present invention, the document size and the data area in the document are converted into coordinate data by the data converting means, and the positional relationship between the document size and the data area is made to have a correlation. This coordinate data is displayed on the display / input means, and the enlargement / reduction coordinate data is input to this display / input means, and the arithmetic means calculates the copy data based on the original and enlargement / reduction coordinate data. Since the copying is performed according to the result, it is possible to change the position of the data area at the time of enlargement / reduction by calculation.

That is, there is an effect that it becomes easy to copy a character or the like to the center of the paper or an arbitrary position at the time of enlarging / reducing copying.
