Alternatively, the location where the trouble has occurred is displayed on a display lamp, for example, so as to prompt the operator to perform the process.

However, simply displaying the above-mentioned message or the place where the trouble has occurred does not allow a user who is unfamiliar with the copying machine to easily perform the trouble processing based on these messages. This problem is particularly serious in a paper jam in which the frequency of occurrence is relatively high and processing is troublesome.

In order to solve such a problem, Japanese Patent Application Laid-Open No. 4-84174 discloses, when a trouble occurs, the content of the trouble as a message on a display unit, and in conjunction with this, the trouble occurrence is described. A configuration for performing an operation of opening a portion has been proposed.

More specifically, when a jam occurs or a situation requiring replacement of the process cartridge occurs, the image forming operation is first stopped. Next, the content of the trouble is displayed as a message blinking on the operation panel, and in conjunction with this, the process cartridge is automatically moved to the retracted position, the upper cover is released, and the unit member at the location where the jam has occurred is removed. Directly displayed by a blinking sign such as an arrow. This makes it possible to easily confirm and remove the transfer material that has become jammed from above the apparatus main body.

Embodiment 5 Still another embodiment of the present invention will be described below with reference to FIGS. 1, 3, 4, and 60 to 66. For convenience of explanation, means having the same functions as the means shown in the above-described embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

The jam processing procedure display device of the present embodiment has an R
While copying a plurality of originals using DH2, ie, RD
During copying in the H mode, if a paper jam occurs in the copying machine main body 1 or a document jam occurs in the RDH 2, a document return guidance display is performed.

The document return guidance is for instructing a method of returning the document to the document stacking section 51 of the RDH 2 shown in FIG. That is, in the case of copying in the RDH2 mode, when the copy operation is stopped due to a jam, it is necessary to return the original on the original stacking unit 51 to the initial state. After the copy is restarted, the copied original is fed without being copied again, and the copy is performed from an uncopied original. In order to perform this operation, a counter for counting the number of originals fed by the RDH 2 is provided in the copying machine main body 1 or the RDH 2, and the copying operation is controlled based on the coefficient value.

When a paper jam occurs, the original may be returned in a duplex mode in which a double-sided original is copied on both sides of a sheet, a single-sided original is copied on one side of a sheet, or a single-sided original is sequentially placed on both sides of a sheet. This is different from the case of the one-side mode in which the copying process is performed. Also, the RDH 2 circulates a document such that copying is performed from the back of the lowermost document on a plurality of documents arranged with the first page facing up on the document stacking unit 51 with the front side facing up. Perform the operation.
Therefore, the original returning method includes the first cycle, ie, the jam during the back side copy (first cycle jam), and the second cycle, ie, the jam during the front side copy after the back side copy even in the duplex mode. (The second circulation jam). Therefore, the document return guidance display is adapted to each of the above cases as shown in FIG. The setting of each mode is performed by operating the copy mode setting unit 112 of the operation panel 101 shown in FIG.

In the original returning method in the case of a jam in the single-sided mode, since the original is not reversed, the copied original group A on the detecting section 67a of the recycle sensor 67 is simply detected as shown in FIG. The operation may be an operation of returning the uncopyed original group B under the copy section 67a.

The original returning method in the case of the first cycle jam in the duplex mode is as follows. First, in the original group A on the detecting unit 67a whose back side has been copied and the back side is facing up, the arrangement in the vertical direction is first reversed. That is, the document is rearranged so that the uppermost document is at the lowermost position, and then the entire document group A is turned upside down and returned to the uncopied document group B below the detection unit 67a. Become.

In the case of the second cycle jam in the duplex mode, the original returning method is as follows. For the original group B under the detecting section 67a, only the back side has been copied and the back side is facing upward.
First, the originals are rearranged so that the arrangement in the vertical direction is reversed.
This is an operation of returning the upper back surface and the front surface to the top of the copied document group A.

In the recycle sensor 67, when copying is started, the detection unit 67a moves to the top of the group of originals stacked on the original stacking unit 51, whereby the original circulation feeding operation of the RDH 2 is performed. , One round of document feeding is detected.

In order to perform the above display operation, FIG.
Is stored in advance in the form of character message data indicating a series of operation procedures for returning the original. The graphic ROM 14
Reference numeral 8 further stores moving image data indicating a series of operation procedures for returning the original. Specifically, RD
In addition to the data representing the outer shape of H2, for example, the cell patterns shown in FIGS. 61 and 62 and the cell patterns shown in FIGS. Then, the CPU 143 and the LCD controller 1
Reference numeral 50 causes the LCD 102 to display the document return guidance by the same operation as that described in the above embodiment.

In the above configuration, in this apparatus, FIG.
As shown in the figure, after the jam guidance is completed (S
21), when the forward key 103 shown in FIG. 4 is operated,
Each document return guidance display is performed according to the case of the jam in the single-sided mode, the case of the first cycle jam in the duplex mode, and the case of the second cycle jam in the duplex mode (S).
22).

For example, in the document return guidance in the case of a jam in the one-sided mode, as shown in FIGS. 61 (a) to 61 (d) and FIGS. 62 (a) to 62 (f), a message instructing a document operation is provided. , Cells 1 to 1 indicating a document moving operation
0 is displayed. These displays indicate the procedure of the above-described document return method, and are shown in FIGS.
(C) shows an operation of picking up the document group A from the document loading unit 51 of the RDH 2. FIGS. 62 (d) and 62 (a) and 62 (b) show the operation of picking up the document group B from the document stacking section 51, and FIGS. The operations to be arranged below are shown in FIGS.
Indicates an operation of disposing the united document groups B and A on the document stacking unit 51.

The message indicating the manuscript operation is displayed only in FIG. 61 (a) in the above drawing, but the actual display on the LCD 102 is also displayed in other states. Is done.

For example, in the document return guidance in the case of the first cycle jam in the duplex mode, FIGS. 63 (a) to (f), FIGS. 64 (a) to (f) and FIG.
As shown in FIGS. 5A to 5D, a message (not shown) for instructing a document operation and a cell 1 indicating a document movement operation
To 16 moving images are displayed. These displays show the procedure of the above-described original returning method.
(B) shows an operation of picking up the document group A from the document stacking unit 51 of the RDH 2. 64C show the operation of rearranging the document group A in the vertical direction, and FIGS. 64B and 64C show the operation of flipping the document group A upside down. I have. 65 (d) to (f) show the operation of picking up the document group B from the document stacking section 51, and FIGS. 65 (a) and (b) show the operation of arranging the document group A under the document group B. 8C and 8D show the operation of disposing the integrated document groups B and A on the document stacking section 51.

Although the message indicating the manuscript operation is not shown in the drawing, the message is actually displayed on the LCD 102 in the state shown in each of the figures, similarly to the case of the jam in the one-sided mode. . The document return guidance in the case of the second cycle jam in the duplex mode is also displayed in the same manner.

The above document return guidance showing a series of operation procedures of the document return method is repeatedly displayed repeatedly until an input key of a copy operation is operated. The input keys for this copy operation are, for example, the copy start key 110 shown in FIG.

The above operation is shown in the flow chart in FIG. That is, for example, when the forward key 103 is turned on after the end of the jam guidance display, the document return guidance display is started (S31), and the guidance display is cyclically displayed (S32). Thereafter, when the input key of the copy operation is turned on after the document return operation is completed (S33), the document return guidance display is terminated and the display is switched to the normal display (S34).

According to the above document return guidance, RD
In the case of a jam in each copy mode using H2, the original returning operation can be performed easily and accurately. That is,
When the original returning method is displayed only by a message or a still image, it is difficult for the operator to understand the original returning method and easily perform an erroneous operation. This problem is particularly remarkable in the jam processing in the duplex mode in which the above-described complicated processing is required. On the other hand, if the document return procedure is displayed as a moving image as in the case of the book original return guidance display, the operator can easily understand the processing procedure and can perform an accurate operation.

Further, since the original return guidance can be displayed on the same LCD 102 following the jam guidance, a series of processing from the copying machine main body 1 side to the RDH 2 side during the jam processing can be performed easily and efficiently. It can be carried out.
