Abstract

PURPOSE:To perform stapling accurately in simple operation by moving and adjusting a range shifting mechanism which aligns a recorded medium for doing the stapling according to a size inputted and designated by a coordinate input means. CONSTITUTION:When a sheet of undefined recording paper is fed manually out of a manual feed tray 154 at the time of a staple mode, if a size is inputted and designated by a read pen switch on a pressure plate 300 with a digitizer, travel of a range shifting plate 509 out of a home position in a staple tray 507 is formed on the basis of the size data, and thereby its positioning takes place with a stepping motor. Then, the recording paper fed manually is copied at a copying machine body 100 and, after being folded by a folding device 400 at need, it is deflected by a flapper 501 and discharged onto the staple tray 507, slipped down through the incline and aligned in a gap with the range shifting plate 509, while if the recording paper is reached to the specified number of sheets, it is stapled by a stapler 511. Thus, stapling is executable accurately in simple operation.

(2) Operation example (Part 1) Next, referring to the flowchart in FIG. 5, the size is set using the digitizer pressure plate 300 when feeding irregular-sized recording paper by manual paper feeding, etc. according to the embodiment of the present invention. We will explain the operation to perform this.

First, the user (operator)
02 is pressed against the electrode surface of the digitizer pressure plate 300 to designate an area, it waits for the lead-venn signal to be turned on (input) by pressing the lead-venn switch 302 (step 5101, see FIG. 2). When the ON signal of the reed vent switch 302 is input, the digitizer pressure plate 30 is immediately turned off.
0 electrode applied voltage is specified on the X axis (step 5102
), convert the voltage corresponding to the pressed position (i.e.,
It is stored in a predetermined area (X-BuF) in the AM 805 (step 5104).

Next, switch the electrode applied voltage mentioned above to Y-axis designation (
Step 5105), the Y-axis input voltage is similarly A/D converted (step 510B), and stored 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 set coordinate input area of the digitizer pressure plate 300 to determine whether it is within the area or outside the area (step 5108). If it is determined that it is within the area, RAM 805
Area specification data address (X-2nd) within
(Y-2nd) is the data address (X-1st).

Shift (transfer) the contents of (Y-1st) (Step 5
109), the area imported this time (ni-BuF),
The contents of (Y-BuF) are (X-ISL), (Y-1
By shifting (transferring) the coordinates 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 data is sequentially designated by the read pen switch 302, the latest data will always be available.

On the other hand, if it is determined in the above step 51013 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 mode key 313 of the irregularly shaped recording paper by comparing it with a predetermined setting value (step 5ill), and if it is the setting value. If it is determined, set the size input flag F in step 511.
2) Return to step 5101 again.

However, in step 5ill, the size input mode key 313
If it is determined that the voltage value is not the same, processing is performed according to the corresponding various keys 310, 311, and 312 (step 5113), and the process returns to step 5101 again. The processing in response to the various keys in step 5113 is not directly related to the present invention, so detailed explanation thereof will be omitted.

J. Operation Example (Part 2) Next, the stable operation of the embodiment of the present invention after inputting the size of the irregularly shaped recording paper as described above is shown in FIGS. 6 and 7 (8) and (B). Explain with reference to.

The stable function is the stable key 625 shown in FIG. 3(C).
If the selection is made and the manual feeding mode is performed, it is determined whether the size input flag F is set by the mode key 313 on the digitizer pressure plate 300 (step 5801). If the size input flag F is not set, operations in other various modes are performed (step 5607). Since the contents of the operations in these various modes are not directly related to the present invention, a detailed explanation thereof will be omitted.

If the size input flag F is set, the memory area (X-
1st), (Y-1st), (X-2nd)
, (Y-2nd) are taken in as irregular recording paper size data (step 5602). Next, the size data (X-1st) (Y-1st)
, (X-2nd) (Y-2nd) Figure 7 (
A) Width shifting plate 5 from home position sensor 51o
It is determined by calculating the movement amount of 09, but it is essentially 1 (Y
-1st) -(Y-2nd) If l is known, the width adjustment amount can be determined (step 5603). This calculation may be performed on the main body side, or size data (X-1st) (Y
-1st).

After passing (X-2nd) (Y-2nd) to the finisher side, the receiving may be performed on the finisher side. The drive signal corresponding to the determined moving unit (width closing amount) is shown in Figure 7 (
8) The voltage is applied to the stepping motor 508 in (8), and the stepping motor 508 is driven via the rack and pinion to move the width shifting plate 509 to the above-mentioned movement amount (step 5604).

Thereafter, the recorded sheets discharged from the main body 100 are aligned on the width adjusting plate 509. Next, the recorded paper bundle is stabilized (step 5605) and discharged to the lower tray (stacker tray) 513 (step 5606). Then return to the main routine.

K. Modification In the above-mentioned embodiment, 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.

[Effects of the Invention] As explained above, according to the present invention, the size of the irregularly shaped recording medium is input using the coordinate input means, and the width plate is moved according to the size. Even in manual paper feeding of a forming apparatus, the effect of stabilizing a stack of ejected recording media by a finisher can be easily and reliably performed with a simple operation.
