DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention comprises an automatic document feeder and a hole detection means for detecting holes in computer form paper, and the automatic The present invention relates to a copying machine capable of performing a copying operation by dynamically transporting the computer form paper by a document transporting device.

In a copying machine equipped with an automatic document feeder, it detects holes in computer form paper (hereinafter referred to as rCFCF documents) and uses this detection signal to feed CF documents. Copying machines that can also make copies of images have been known for some time.

However, with conventional copying machines, if there is a part in the middle of a continuous CF original or stacked sheet original that does not require copying, in order to copy only the necessary pages of the CF original or sheet original, it is necessary to copy all pages. How to remove unnecessary pages after copying, how to separate unnecessary pages before copying and copy in several batches, and how to temporarily stop copying when unnecessary pages start to be copied during copying. This method had no choice but to manually send unnecessary pages of CF or sheet manuscripts, store them in the output storage box, and then resume copying from the necessary pages. According to the above, copying of unnecessary pages is wasted, extra work is required to cut out unnecessary pages, and it is necessary to set CF originals or sheet originals many times or manually create CF originals or sheet originals. The first problem is that it is a hassle to have to transport and store it.

Problems to be Solved by the Invention The present invention solves the above-mentioned problems in the prior art, and provides a copying machine that has good operability and is capable of copying CF originals with good efficiency. It is an object of the invention of claim 2 to provide a copying machine that can achieve the above object without changing the main body operation part, and the invention of claim 3 is an object of the invention of claim 2. 2
In addition to the above invention, it is an object of the present invention to provide a copying machine with improved operability, and a fourth object of the invention is to copy a CF original or a sheet original with good operability and efficiency.

In order to solve the above-mentioned problem, the invention of claim 1 includes an automatic document feeder and a hole detection means for detecting holes in computer form paper, and the hole detection means detects holes in computer form paper. In a copying machine that performs a copying operation by automatically transporting the computer form paper by the automatic document feeder based on the number of holes determined, the copying machine interrupts the copying operation and transports the computer form paper. The invention of claim 2 is characterized in that, in addition to the above-mentioned features, an interrupt key or an interrupt key that interrupts the currently executed copy mode among a plurality of copy modes to enable execution of another copy mode is provided. A claim characterized in that the main body operation section is provided with a clear stop key capable of canceling the copy mode and stopping the copying operation, and the above-mentioned forwarding is executed and canceled by pressing the separation key or the clear stop key. According to a third aspect of the present invention, in addition to the features of claim 1 or 2, the operation section is provided with a numeric keypad, and the number of pages to be forwarded is specified by the numeric keypad. Furthermore, the invention according to claim 4 is characterized in that the automatic document feeder is provided with a feed setting means for conveying the document and starting the copying operation, and then interrupting the copying operation and conveying only the document.

According to the invention of claim 1, it is possible to interrupt the "feeding", that is, the copying operation, and only transport the computer form paper. For those parts that are not available, operability and copying efficiency can be improved by executing the send remote. In this case, since the copying operation is not performed while the original is being fed, there is no need for time related to exposure of the original, so the transport time is shorter than when copying, and the transport speed during this period is increased. This makes it possible to further improve efficiency.

According to the invention of claim 2, since the feed operation can be executed and canceled after using the interrupt key or the clear stop key normally provided on the main body operating section of the copying machine, one main body operating section does not have an extra operation key. It is possible to perform a feed operation without the need for a .

According to the third aspect of the present invention, the number of pages to be skipped is specified using the numeric keypad on the operation unit, so there is no need for a person to judge when to cancel the skipping and perform a cancellation operation.

According to the invention of claim 4, the automatic document feeder is provided with a blank feed setting means for interrupting the copying operation and feeding only the document, and
It is possible to feed not only F originals but also sheet originals.

FIG. 1 is an explanation of the case where a CF original, which is computer form paper, is conveyed and copied in the copying machine of the embodiment.

The CF original is placed on the CF original table 202 located on the right side of the automatic document feeder 100 attached to the main body 201 of the copying machine.
and inserted into the automatic document feeder 100 via the sensor part 116. The CF originals that are sequentially transported to predetermined positions on the contact glass 203 by the automatic document feeder 100 are copied in a normal copying process in the main body 201 of the copying machine, and then sent out along the upper surface of the original tray 204 and sent to the ejection bin. As the paper advances, it changes direction downward after passing the document receiver 204, reaches the discharged document storage box 205, and is stored therein.

FIG. 2(a) shows the arrangement of the guide section for a CF original, and FIG. 2(b) shows the arrangement of the sensors of the sensor section 116.

The CFfi document is conveyed while being guided at both ends by a side guide 115 and a sensor section 116 that also serves as a site guide. Side guide 115 and sensor section 116
are capable of sliding in synchronization in opposite directions to accommodate the width of the CF original.

The sensor unit 116 includes a document detection sensor 101 that detects the presence or absence of a document, and perforation detection sensors 102 and 103 that are an example of hole detection means that detects the presence or absence of holes in the CF document placed in the paper feed port. has been done.

Further, a document edge detection sensor 104 is provided on the automatic document feeder 100 side to detect the document edge.

FIGS. 3 and 4 are control block diagrams of such a copying machine, with FIG. 3 showing its overall system and FIG. 4 showing its C.
Fi document transport reverse transport control section.

In FIG. 3, when the input section of the operation section is operated, a control operation is performed by the operation section control panel, a display is displayed on the operation section, and signals are exchanged with the main control panel of the main body. The driving portion of the copying machine is driven by the main body moving portion. On the other hand, signals are also exchanged between the main body main control board and the automatic document feeder control board, and the drive unit drives the apparatus.

FIG. 4 shows a portion of the control section of the automatic document feeder 100 related to CF document feed. A control unit 105 that performs conveyance and stop control of the CF original receives signals from the original detection sensor 101, perforation eye detection sensors 102 and 103, and original edge detection sensor 104, and also receives signals from the copying machine main body and the CF Timer 1 that measures the document transport stop time
06, and based on these signals, signals are sent to the drive control unit 107, and the automatic document feeder 1
Controls the driving of the servo motor, clutch, solenoid, etc. (not shown) of the 00 main body.

FIG. 5 shows an example of the arrangement of keys, etc. on the operating section.

In the figure, on the right side are a mode clear key 1, an interrupt key 2 for interrupt copying, an enter key 3,
Various operation keys are provided, such as a print key 4, a numeric keypad 5, and a clear stop key 6 for canceling the copying mode in progress and stopping the copying operation.

Next, the normal operation when transporting a CF original will be explained mainly with reference to FIGS. 1, 2, and 4.

The CF original placed on the CF original table 202 is set so that the perforation at the leading edge of the first sheet is aligned with the original reference position on the contact glass 203. Next, the document side guide 115
and the sensor unit 116 to adjust the feeding state of the CF original and the perforation position (hole position).

When the document edge sensor 104 detects the leading edge of the document, the control unit 105 controls the drive control unit 107 to prepare for document feeding. At this time, the document detection sensor 101 and perforation detection sensors 102 and 103 of the sensor unit 116 each detect the state of the document. For example, the original detection sensor 10
1 detects the presence or absence of a document, that is, whether one end of the document has reached the sensor section 116, and perforation detection sensors 102 and 103 detect whether there is a hole in the document, that is, whether the document is a CF document. Detect whether or not.

Based on the detection signals of the document detection sensor 101 and the perforation detection sensors 102 and 103, the control unit 105 determines that a CF document has been inserted when a hole is detected by the perforation detection sensor 102 and 103, and inserts the CF document. The CFF mode for transport is selected, and the CFF mode is notified to the drive control unit 107 and the copying machine main body.

Note that if no holes are detected by the perforation detection sensors 102 and 103, it is determined that the document is a sheet document.
The 5ADF mode (operation mode in which sheet originals are inserted into the paper feed port one by one) is selected, and the 5ADF mode is notified to the drive control unit 107 and the copying machine main body. After that, when you press the print key 4 (Fig. 5) on the main body of the copying machine, the drive control section 1
07 executes drive control of each section, the CFR document is conveyed, and the copying process is started.

FIGS. 8 to 14 are flowcharts for transporting a CF original as described above.

FIG. 8 shows the flow up to the CFF mode. C.F.
A sensor 10 detects whether a document is set on the document tray.
1 (original detection sensor) and when sensor 101 is turned on, a flag (FED
IN) is "1" or not, and if it is "1", the counter (CFSTPC
). Next, the CF document control job counter (CF
JOBC) is set to 1, and the CFF mode flag (
CFFMDF) to "1".

Figures 9 and 10 show the CFF mode.
This is a flow for detecting and counting perforations in an FyK draft.

FIGS. 11 to 14 show a control flow for transporting a CF original. In FIG. 11, CFF mode (CFFMDF
=1), control is performed so that subroutines are specified and executed in sequence according to the contents of the job counter (CFJOBC).

When the job counter (CFJOBC) is "1",
Execute the PSIIO flow shown in FIG. That is,
Turn on each motor, clear the hole number counter (CFFCNT), and then set 2 to the job counter.

In the 2O-PS120 in FIG. 13, it is determined whether the sensor 101 is on or not, and if it is on, the contents of the stop hole number counter (CFSTPC) of the size set at the start and the counted hole number counter (CFFCNT) are determined. If they match, each motor is turned off, the job counter is reset, and the conveyance is completed.

If the sensor 101 is off, it is determined that the final page of the CF original has been reached, and the number of stop pulses for the final page is set (M2STPC←75).

Then clear the M2 pulse counter and start the next CFJOB.
Set "3" to C.

FIG. 14 shows the processing flow for the final page. The set value of the number of stop pulses (M2STPC) is the number of transport pulses from the sensor 104 (document edge detection sensor) to the reference position. When the sensor 104 turns off and detects the trailing edge of the last page, it synchronizes with the M2 transport motor. When the number of pulses generated by the M2PLC matches the set value of the number of stop pulses, each motor is turned off and the conveyance is completed.

The normal conveyance of a CF original has been described above.

Next, the relationship between conveyance of a CF original and copying operation when the present invention is implemented will be explained.

In this embodiment, if there is a page that does not need to be copied in the CF document after the CFi document has been conveyed and has been subjected to copy processing, when the unnecessary page comes to the paper feed section, the interrupt key 2 or the clear stop key is pressed. 6 (Figure S) is pressed. When any key is pressed, a page that does not need to be copied is transported, but no copying operation is performed for this page, and the CF original continues to be printed until either the 1 interrupt key 2 or the clear stop key 6 is pressed again. When any key is pressed again, the copying operation is restarted after the current CF document is conveyed.

In another embodiment (the example shown in FIG. 7), when any of the keys mentioned above is pressed, the C
Stop feeding the FM document and wait for copying instructions,
If you input the number of pages that do not need to be copied using the numeric keypad 5 (Fig. 5) and press the print key 4 again, the CF original will only be transported for the number of pages entered using the numeric keypad 5 without copying, and the specified number of pages will be transferred. The copying operation is controlled to start after conveyance.

FIG. 6 is a flowchart when the interrupt key 2 is used in the above.

If each input check number CF original is set, the CF
The original mode flag is set to "1" and it is determined whether the print key 4 (FIG. 5) has been pressed. (Step 1
). If print key 4 is on, flag FCPST
If P is not "1", execute a copy control routine;
Copy the CF original (step 2).

CF77! If more documents are set, a CF document transport command will be sent (step 3).If interrupt key 2 is not on and flag FCPSTP is not "1",
Reset this to "0" (step 4), then execute the copy control routine and copy the CF original (step 2')
.

When interrupt key 2 is pressed, flag FCPSTP is set to “
1" (step 5), determine this flag, and if it is "1", do not perform any copy control operation (step 2'), only transport the CFyK document (step 3), and press the interrupt key. 2 is not pressed again, if the flag FCPSTP is "1", this flag is not reset to "0" (step 4), and the copy control routine is passed (step 2'), and the CF original is transported. (Step 3).

When interrupt key 2 is pressed again, the flag FCPSTP
If it is "1", it is reset to "0", a copy control routine is executed, and copying of the CF original is resumed.

Although FIG. 6 shows the case where the interrupt key 2 is used, the clear stop key 6 can be used in place of the interrupt key 2 to perform exactly the same flow.

FIG. 7 shows the case where the interrupt key 2 and the numeric keypad 5 are used, and shows the contents of the frame 300 in FIG. The explanation will include FIG. 6 as well.

If the interrupt key 2 is pressed and the flag FCPSTP is not "1", specify the number of unnecessary copies using the numeric keypad 5 and press (
For example, set the counter FEDCU=5) to "1" and set the flag FCPSTP to step 5'), and set C without copying control.
If the F original is transported (steps 2' and 3 in Figure 6) and the interrupt key 2 is not pressed again, the flag FCPS is
It is determined that TP is "1" and this flow is repeated without performing a copying operation until the counter reaches "O".

When the counter reaches "0", the flag FCPSTP is set to rQJ.
Reset step 4') to perform copy control again.

Of course, in this case, the clear stop key 6 can be used instead of the interrupt key 2. Further, in the above example, the copying operation is restarted automatically, but it is also possible to wait for a copying instruction after conveying a page that does not require copying, and restart the copying by pressing the print key 4.

In the above embodiment, the interrupt key 2 or the clear stop key 6 is pressed during the transport of the CF original to specify pages that do not need to be copied, but pages that do not need to be copied can be arbitrarily set before transporting the CF original. However, it is also possible to control the setting page so that the copy control routine is not performed without pressing the interrupt key 2 or the like during the process.

Furthermore, in the portion where only the CFJJX document is transported without performing a copying operation, the processing capacity can be improved by increasing the transport speed.

In addition to the above-mentioned CF original feeding, there are cases where it is necessary to start feeding a sheet original.

For example, when one copy of the stacked originals is to be copied, and the others do not need to be copied. An example of solving this problem is shown in the 15th example.
Shown below.

In the operating section shown in FIG. 15, a feed setting key 7 is further provided in addition to the keys of the operating section shown in FIG. The first feed setting key 7 has the function of interrupting the copying operation and feeding only the original after the copying machine has conveyed the original and started the copying operation. The operation in the feed mode using the feed setting key 7 will be described below.

The feed mode setting check flow shown in FIG. 16 will be explained.

First, start with the feed setting key 7 on the main body operation section shown in Fig. 15.
Determine whether or not has been pressed. When the enter key 3 is pressed, proceed to the next step, input the settings for the start page using the numeric keypad 5, and when the enter key 3 is pressed, it is assumed that the setting of the start page is completed and proceed to the next step. At this time, the numeric keypad data of the starting page is stored in the counter 5TCUT. Next, in the same way as 5 above, set the start page and end page, and input the numeric keypad data to the counter 5TPCUT.
to be memorized.

Then, the feed mode setting flag FNAKA is set to "1", the transport counter FEDCNT is cleared to "0", and the process returns.

Next, the operation when remote sending is set will be explained.

In FIG. 17, step 1 is entered with a new addition of ``send remote setting check,'' but otherwise the steps are the same as steps 1, 2, and 3 in FIG. 6, so a description thereof will be omitted.

In step 2, send remote setting flag FNA from
It is determined whether KA is "1" or not, and if it is "1", then it is determined whether or not the copy skip flag FSXIP is "1". If it is “0”, it is N.

Then, it is determined whether the number of transported originals has reached the feed start page set above, and if it has reached (
Copy skip flag FS in STCUT=FEDCNT)
Set KIP to "1".

If FSXIP is set to "1", the document transport command is sent without executing the copy control routine.

If FSKIP is “1” in step 2, step 3
Then, it is determined whether the number of transported documents has reached the end page as set above, and if it has reached (
STPCUT<FEDCNT) controls to reset the copy skip flag FSKIP to rQJ, reset the mode setting flag FNAKA to rQJ, and restart the copying operation.

FIG. 18 shows an operation flow in the feed mode when conveying a sheet document, in contrast to FIG. 17 for conveying a CF document, and since it is almost the same as the explanation for FIG. 17, the explanation will be omitted.

According to the present invention as described above, in the invention of claim 1, by providing the blank feed function, it is possible to prevent the occurrence of copy paper wastage when copying a CF original, and also to make the operation easier. Copying efficiency can be improved by reducing the speed and copying time.

In the invention of claim 2, by using an interrupt key or a clear stop key that is normally provided in a copying machine, there is no need to provide an extra key or the like on the main body operation section, and it is possible to make a request without complicating the main body operation section. The effect of the invention of item 1 can be obtained.

Further, in the invention of claim 3, by specifying pages that do not need to be copied using the numeric keypad, in addition to the effects of the invention of claim 1 or 2, the operability can be further improved.

Furthermore, in the invention of claim 4, both the CF original and the sheet original can be fed from the beginning, thereby improving the copying efficiency.
