BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document reading apparatus such as a copying machine, a facsimile machine, and a multi-function machine having multiple functions such as a copying function and a fax function.

[0002]

2. Description of the Related Art In general, some copying machines and facsimile machines can read both the front and back sides of a single original. On the other hand, when a jam occurs during the reading of a document, there is also one that detects the jam and notifies the jam occurrence.

[0003]

In the above-mentioned document reading apparatus such as a copying machine and a facsimile machine, if a jam is detected during the reading of a double-sided document, the fact that the jam has occurred is notified. However, since it is only a notification of the occurrence of a jam, it is difficult to immediately determine which document has been read, or whether to start rereading from the front or back, and it is troublesome to reset and restart reading. There was a problem that required.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an original reading device in which an original can be easily reset when a jam occurs.

[0005]

A document reading apparatus according to the present invention comprises a document reading section and a first document which constitutes one side of a document.
A document reversing unit for reversing the first surface and the second surface to supply the document to the document reading unit, and controlling the document reversing unit so that the document reading unit alternates between the first surface and the second surface. In a device including a reading control unit for reading in sequence and an image storage unit for storing read original data, a jam detecting unit for detecting a jam during reading of an original, and a predetermined surface (for example, back surface) of the original during reading When a jam is detected,
Means for displaying the number of pages to be reset.

In this document reading apparatus, when a jam is detected, the number of pages to be reset is displayed, so that the operator can immediately reset the document to be read again.

Further, in the document reading apparatus of the present invention, when the reading is restarted after the resetting, the other side (for example, the front side) of the original of the reset page is different from the predetermined side.
Is skipped, and reading from the predetermined surface (for example, the back surface) is effective because resetting can always be performed from the other surface (the front surface).

Further, if the page to be reset is a page number of another surface (for example, front surface) different from the predetermined surface, the reset document can be placed on the other surface, for example, front surface. Can be set and is effective.

Further, it has a function of detecting the occurrence of a jam during the reading of a document and notifying the occurrence of the jam.

In the facsimile apparatus of this embodiment,
The reading of the front and back of the original will be briefly described. In FIG. 2, documents are stacked in the document storage unit 31 with the front side facing up. When the reading is started, the original 32 is fed from above. The original 32 advances along the conveyance path 33 and the main roller 34, the line sensor 7a of the scanner 7 and the front of the original 32 face each other, the original is read by the line sensor 7a, and the read original 32 is on the side of the conveyance tray. It stops at the stop part 35. Next, when reading the document on the back side, the main roller 34 is conveyed so as to rotate once, as shown in FIG. As a result, the front and back of the original 32 are reversed, and the back of the original 32 and the licensor 7a face each other, so that the original 32
The original on the back of the page is scanned. It should be noted that the document presence / absence detection sensor 36 in the document storage unit 31 is provided in the line sensor 7a of the conveyance path 33.
A sensor 37 for detecting the document size is provided in the front.

Next, the processing operation of the apparatus according to the embodiment of the present invention will be described with reference to the flow charts shown in FIGS. When the process is started, the document is set in step ST1. Then, the process proceeds to step ST2. In step ST2, it is determined whether or not the start key has been pressed. When the start key is pressed, the process proceeds to step ST3. In step ST3, the page count is cleared to 0. Then, the process proceeds to step ST4.

In step ST4, it is determined whether or not the original is read on both sides. Whether to perform double-sided scanning is preset in the machine by operating a button on the operation unit. In the case of double-sided reading, the process proceeds to step ST5. On the other hand, if it is not double-sided scanning, step ST
Go to 6. In step ST5, the double-sided status is turned on. Then, the process proceeds to step ST7.
In step ST6, the double-sided status is turned off. Then, the process proceeds to step ST7.

In step ST7, the document is fed and the reading is started. Then, the process proceeds to step ST8. In step ST8, first, page 1 of the table,
That is, reading of the first page is started. Then, it transfers to step ST9. In step ST9, the page count is incremented by 1, that is, 1. Then, the process proceeds to step ST10.

In step ST10, it is determined whether a jam has occurred. If no jam has occurred, the process proceeds to step ST11. On the other hand, if a jam occurs, the process proceeds to step ST15. In step ST11, it is determined whether the reading of one page is completed. When reading is completed, step ST12
Move to. On the other hand, when the reading is not completed, the process returns to step ST10 and the jam detection is performed until the reading of one page is completed.

In step ST12, it is determined whether the double-sided reading status is ON. In step ST5, if the double-sided status is ON, the determination is YES.
In S, the process proceeds to step ST13. On the other hand, step S
If the double-sided status is ON at T6, the determination is NO and the process proceeds to step ST14. In step ST13, it is determined whether the page count is an even number. If the page count is an even number, the process proceeds to step ST14. On the other hand, if the page count is not an even number, that is, an odd number, the process returns to step ST7 to start reading the back side which is the next page (even number page). Step ST1
In 4, it is determined whether or not there is a next page. Whether or not the next page exists is determined by the output of the document presence / absence detection sensor 36. If there is the next page, the process returns to step ST7 to start reading the next page, that is, the front side of the next original. If there is no next page, the determination in step ST12 is double-sided status OFF, that is, single-sided reading, or the determination in step ST13 is an even number, so there is no document to be read next, and the process ends.

In step ST15, the alarm buzzer is turned on. This informs the operator that a jam has occurred. Then, the process proceeds to step ST16. In step ST16, "Document jammed" is displayed on the display. Next, step ST
Go to 17. In step ST17, it is determined whether the jam is released. If the operator performs the jam removal process by an alarm or a warning display, the determination result is YES. Then, step ST18
Move to.

In step ST18, it is determined whether the double-sided reading status is ON. Double-sided scanning status ON
In the case of, it transfers to step ST19. On the other hand, if the double-sided reading status is not ON, the process proceeds to step ST21. In step ST19, it is determined whether the page count is an even number. If it is not an even number, that is, if it is an odd number, the process proceeds to step ST21. On the other hand, if it is an even number, the process proceeds to step ST20.

In step ST20, the page number of page count-1 is displayed. Here, since the jam has occurred on an even page, that is, the back side is being read, the front side page that has already been read is displayed. Then, assuming that the page on the front side is the page XX, the message "Please reset the document page XX" is displayed on the display unit. Then, the process proceeds to step ST22. In step ST22, it is determined whether the start key has been pressed. Since the page XX of the original is the front page when a jam occurs, when the operator resets the original with this page as a table and presses the start key, the determination in step ST22 becomes YES and step ST23 Move to.

In step ST23, it is determined whether the double-sided reading status is ON. Step ST1
If the processing of 9 and ST20 has passed, the determination is YES, and the process proceeds to step ST24. In step ST24, it is determined whether the page count is an even number. When the processes of steps ST19 and ST20 have been completed, this determination is also YES and the process proceeds to step ST25. In step ST25, the original of page XX, that is, the front side is not read, only the feed is performed, and then the process proceeds to step ST7. Then, thereafter, reading is started from the page next to the XX page, that is, the back surface in which the jam has occurred.

In step ST21, "Display page count and reset document page XX" is displayed on the display. Then, step ST2
Move to 2. When the operator sees the display and resets the jammed page XX page and subsequent pages and presses the start key, the determination in step ST22 is YES, and the process proceeds to step ST23. In this case, since a jam occurs when reading one side, the determinations in steps ST23 and ST24 are both NO, the process of step ST25 is skipped, and the process returns to step ST7. Then, the document reading is started from the jammed page.

[0024]

According to the present invention, while reading a document,
When a jam is detected, the page to be reset is displayed, so that the document whose reading should be restarted can be reset immediately.

Further, a jam occurs during the reading of the back side of the original, and the number of pages to be reset is displayed. By reading the original of this page after the reset, the front side is skipped and the original is read from the back side, so that it is efficient. And, reading can be resumed properly.

Also, the page to be reset that is displayed is
By setting the page number on the front side, a normal front side set can be made even when resetting, and it is possible to perform resetting without discomfort.
