Abstract

PURPOSE:To easily perform an image shift even in case of manually supplying paper by inputting the size of undefined medium to be recorded by a coordinate input means, calculating a coordinate and moving the image of an original to the coordinate. CONSTITUTION:By pushing two points, for example, an A point and a B point or an A' point and a B' point, on an area specification part 301 with a read pen 302, an area surrounded with A-A'-B-B'-A is specified. Next, by pressing a mode key 312 or a size input key 313 with the read pen 302 and, finally, by pushing a register key 311, the area specified data is confirmed to be registered in an internal memory. In case of performing copying thereafter, functions for trimming, masking or specifying the size of undefined recording paper are actuated according to the registering and the image of the original is moved to the coordinate. Thus, the image shift can be easily performed even in case of manually supplying the paper.

! ,! 111 Example (Part 1) Next, with reference to the flowchart in FIG. The operation of making settings will be explained.

First, when the user (operator) presses the lead pen 302 against the electrode surface of the digitizer pressure plate 300 to specify an area, waits for the lead pen (X) pressed by the lead pen 302 to turn on (input) (step 5101, 2
(see figure), when the ON signal of the lead vent 302 is input, the voltage applied to the electrode of the digitizer pressure plate 300 is immediately designated as the X-axis (step 5102), and the voltage corresponding to the pressed position (i.e., the X-axis input voltage ) to A/D (
Analog/digital) conversion step 5103),
The converted digital value is stored in a predetermined area (X-BuF) in the RAM 805 (step 5104).

Next, switch the electrode applied voltage mentioned above to Y-axis designation (
Step 5105), similarly A/D converts the Y-axis input voltage (Step 5108), and stores it in a predetermined area (Y-BuF) in the RAM 805 (Step 5107).
.

Next, the data of the area (Y-BuF) is compared with the maximum value within the preset coordinate input area of the digitizer pressure plate 300 to determine whether it is within the area or outside the area (step 5108). RAM 80 if determined
Area specification data address (X-2nd) within 5,
(Y-2nd) Data address (x-txt).

Shift (transfer) the contents of (Y-1st) (Step 5
109>, the area imported this time (X-BuF),
The contents of (Y-BuF) are (X-1st), (Y-1
By shifting (transferring) to st), the coordinates of the specified area are refreshed so that the latest two points of data are always stored, and the process returns to step 5101 again. With this, even if the data is sequentially specified by the lead vendor 302, the latest data will always be available.

On the other hand, if it is determined in the above step 5108 that it is outside the area, one of the mode setting keys 312 and 313 is scanned. Then, it is determined whether the data value of the area (X-BuF) is the voltage value of the size input key 313 of the irregularly shaped recording paper by comparing it with a predetermined setting value. If it is determined, set the size input flag F (step 5112),
The process returns to step 5101 again. However, step 5111
If it is determined that the voltage value is not the voltage value of the size input key 313, the process corresponding to the corresponding various keys 310, 311, 312 is performed (step 5113), and the process returns to step 51 again.
Return to 01. The processing in response to the various keys in step 5113 is not directly related to the present invention, so a detailed explanation thereof will be omitted.

J. Operation Example (Part 2) Next, the image shift operation of the embodiment of the present invention after inputting the size of the irregularly shaped recording paper as described above will be explained with reference to FIGS. 6 and 7. .

First of all, image shift (center shift!!!]) is
As shown in Figure 7, for example, suppose that an image as shown in (A) is formed on an A4-size original, and the coordinates of the center position of this original are (Xl, Yl). When copying is performed on A3 size recording paper, the copying shown in (8) is usually performed. Therefore, in order to perform image shift to move the original image to the center position of the recording paper as shown in (C), feed the recording paper, start registration with the registration roller 159, and then start optical system scanning. A specific operation of the 0th order that can shift the center of the image by α in the X-axis direction by delaying the image by a certain amount of time will be described with reference to the flowchart of FIG.

As shown in FIG. 6, when paper is fed in the manual feed mode, the size input key 3 is placed on the digitizer pressure plate 300.
13, it is determined whether or not the size input flag F is set (Step 5601), the size input flag F is set.
If not set, processing in various modes is performed (step 5609).

Since the fi-embedding contents in various modes are not directly related to the present invention, a detailed explanation thereof will be omitted.

On the other hand, if the size input flag F is set, the memory areas (X-1st), (Y-1st), (X-2n) described in steps 5109 and 5ilo above are
d) , (Y-2nd) data (editor input data) respectively as recording paper size data (x-pt),
(y-p +), (X-h), (Y-P2) in a predetermined area of RAM8O5 (step 56
02).

Next, 'A I (X-
P + In consideration of the above, α is set as the value of a timer for delaying the start of scanning of the scanning optical system for reading the original g4 (step 5604).

After that, the above-mentioned timer (CP
O301's internal timer) starts timing (step 5).
605), Wait for the timer to time up (step 5606), and when the timer times up, start scanning with the document reading scanning optical system (step 560).
4) Perform copy processing (step 5608).

In this way, since the scanning of the scanning optical system is delayed based on the recording paper size data input on the digitizer pressure plate 300, image shift (
Sensor 8! it).

K. Modification In the above-mentioned embodiment of the present invention, manual paper feeding was explained as a paper feeding means for irregularly shaped recording paper of unknown size.
As a paper feeding means for this irregularly shaped recording paper, there is also a so-called universal cassette which can load irregularly shaped recording papers, and it goes without saying that the present invention can also be applied to paper feeding by this universal cassette.

Additionally, a copying machine, generally called a digital copying machine, is provided that once stores an image of an original in a storage device and then uses the data in the memory to write on a recording medium using a laser or the like. However, if such a copying machine is used, it is possible to shift the image not only in the recording paper conveyance direction and the optical system scanning direction, but also in the Y-axis direction perpendicular to these directions. and corner movement becomes possible.

[Effects of the Invention] As explained above, according to the present invention, the size of an irregularly shaped recording medium is inputted using the coordinate input means, and a predetermined position ( Since the coordinates of (for example, 1f center position) are calculated and the document image is moved to the coordinates, the effect of easily shifting the image to the depth can be obtained even in manual paper feeding.
