DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device of an image forming apparatus such as a digital copying machine which executes a copying function, a scanning function, a printing function, a facsimile function and a function of communicating with an external device.

[0002]

2. Description of the Related Art Conventionally, in a digital copying machine or the like which forms an image by exchanging image data with a plurality of image input means and a plurality of image output means, image data is input at an arbitrary timing from each image input means. be able to.

However, there are cases where a plurality of print jobs are separately input from image input means and output by the same output means,
If a new print job is input during image output,
The print job is stored in the storage unit and waited until the image forming order for each print job comes. If it becomes the order of the image output of the waiting print job,
If it is determined that an image cannot be formed by the image forming apparatus that performs the output operation, and the output operation is interrupted, the efficiency of the image formation output operation is greatly reduced.

To solve such a problem, Japanese Patent Laid-Open Publication No.
No. 1797 discloses a case in which sheets of a print job waiting for output are not currently in the sheet feed tray, and the sheet can be replaced before another output order comes due to the presence of another tray not to be used. Displays a message requesting the paper replacement on the display device, prompts the user to replace the paper in the tray, and prevents the image forming apparatus from interrupting the output operation in the middle, so that the print job can be continued. I can do it.

However, in the display device of the conventional image forming apparatus described above, for example, there is no empty tray at the present time when the print job is in a waiting state, and a different size for the print job is used. Even when the important setting conditions of the print job are not satisfied, such as when the paper cannot be replaced, a situation may occur in which nothing is displayed on the display device. For this reason, the user may erroneously determine that there is no problem in forming an image when looking at the display unit.

In addition, if there are many print jobs in a waiting state, and if there are a plurality of print jobs that cannot output images with the currently operating image forming apparatus, the number of print jobs that can be displayed is limited. There is also the problem that multiple items cannot be displayed.

The present invention has been made in view of such circumstances, and it is possible to easily determine whether or not the setting conditions of a plurality of print jobs in a waiting state are suitable for the state of the image forming apparatus. It is an object of the present invention to provide a display device of an image forming apparatus capable of allowing a user to quickly and easily determine how to deal with a print job in a waiting state.

<Description of Print Job Display Method in the Present Embodiment> The display state of a waiting print job on the color LCD 104 having the above-described configuration will be described below. In addition,
FIG. 21 shows a list of print job registration information to be set.

When a print job is input to a digital color copying machine, it is determined whether or not the print job registration information is valid for the current state of the digital color copying machine. For example, if the print job includes setting items for color printing or black-and-white printing, it is determined whether the settings are valid according to the flow shown in FIG.

First, at step S1, the message flag ms
Reset g_flg_BW1 and msg_flg_BW2. This message flag, as shown in FIG. 22, constitutes Bit7 and BiL3 of the entire 8 bits.

Next, in step S2, it is determined whether or not the job is a black-and-white job. If the job is a color job, the process proceeds to step S3.
Alternatively, it is determined whether a failure has occurred. If the color job is impossible / failure, the process proceeds to step S4.
msg_flg_BW1 is set.

If it is determined in step S3 that a color job is possible, the flow advances to step S5 to determine whether or not the color toner has run out. If there is a color toner that has run out, the process proceeds to step S6, and msg_fl
g_BW2 is set, and data on the color without toner is added as msg_dat_BW2. If it is determined in step S5 that there is a color toner, the process ends.

Here, when there is a setting for stapling as post-processing in the print job, it is determined whether or not the setting is valid according to a flow as shown in FIG.

First, in step S11, msg_flg_ST1 is reset, and msg_flg_ST2 is reset. As shown in FIG. 22, this message flag constitutes Bit5 and Bit2 of the entire 8 bits.

Next, in step S12, it is determined whether or not the job is a staple job. If the job is a staple job, the flow advances to step S13 to determine whether or not the stapler has failed. If a failure has occurred, the process proceeds to step S14, and msg_flg_ST1 is set.

If it is determined in step S13 that there is no failure, the flow advances to step S15 to determine whether or not there is a stapler. If there is no stapler, the process proceeds to step S16, and msg_flg_ST2 is set. If there is a stapler, the process ends.

When there is a setting item of double-sided printing / single-sided printing as a processing item, it is determined whether or not the setting is valid according to the flow shown in FIG.

First, msg_flg_DUP is reset in step S21. As shown in FIG. 22, this message flag constitutes Bit 6 of the entire 8 bits.

Next, in step S22, it is determined whether or not the job is a one-sided job. If the determination result is a double-sided job, the process proceeds to step S23, where it is determined whether or not the double-sided function has failed.
Proceed to 4 to set msg_flg_DUP. If no failure has occurred, the process is terminated.

The processing items include output size, paper type, tray No. If there is a setting item of, it is determined whether the setting is valid or not according to the flow shown in FIG.

First, in step S31, it is determined whether or not a tray is automatically selected. If the selection is automatic, the process proceeds to step S32, where the tray No. Is assumed to be k = 1.

Next, in step S33, it is determined whether or not the output size corresponds to tray k, and if so, the process proceeds to step S34, where the paper type is set to tray k.
Is determined.

If it is determined in steps S33 and S34 that the output size and paper type do not correspond to the tray k, the process proceeds to step S36, where 1 is added to the value of k (k + 1), and step S37 is performed. Proceed to. In step S37, it is determined whether or not the value of k exceeds the total number of trays. If not, the process returns to step S33 and repeats the processing.

If it is determined in step S34 that the paper type corresponds to the tray k, the process proceeds to step S3.
Proceed to 5 to reset msg_flg_TRY.

If it is determined in step S37 that k exceeds the total number of trays, the process proceeds to step S3.
In step 8, msg_flg_TRY is set, and msg_dat_SIZ representing the output size, msg_dat_TYP representing the paper type, and msg_dat_TRY = 0 representing that there is no usable tray are added as data.

On the other hand, if the tray selection is to be performed manually in step S31, the flow advances to step S39 to determine whether the output size corresponds to the tray N when the tray N is selected. If the output size corresponds to tray N, the process proceeds to step S40, and if the paper type is tray N
Is determined. If the paper type corresponds to tray N, the process proceeds to step S41 and msg_flg_T
Reset RY. Step S39 or step S
If it is determined in step S40 that the tray N is not supported, the process proceeds to step S42 and msg_flg_TRY
And msg_dat_SIZ representing the output size, msg_dat_TYP representing the paper type, and msg_dat_TRY = N representing that the selected tray is N as data.
Is added.

As in each case described above, if the apparatus status does not correspond to the setting of the print job, a message flag is created in which 1 is input to that bit. The display performed according to the job executable / impossible state determined in this manner will be described below.

FIG. 9 is a flowchart showing a procedure for determining the display color of the menu bar of each print job when a list of print jobs in a waiting state is displayed.

First, in step S51, the parameter k is set to 1 and m is set to 10000000B. In step S52, it is determined in step S53 whether the same bit of the above-described message flag created for the input print job matches the bit indicating 1 of m.

[0097] If the two values match according to the determination in step S53, the flow advances to step S54 to set disp_dat = k. Then, in step S55, disp_dat stored in the memory 102 of the operation board unit 49 in FIG.
, Select the display color of the print job on the menu bar.

On the other hand, if the results of the determination in step S53 do not match, the flow advances to step S56 to set the value of k to 1
(K + 1), and shifts the bit order of m to the right by one bit, and then proceeds to step S57. In step S57, it is determined whether or not k exceeds 8, and k is 8
As long as it does not exceed, the process returns to step S52 to repeat the processing.

Here, each bit of the message flag is changed from the most significant bit Bit7 to Bit0 by 1 of m.
It is sequentially determined whether they match the bits of
In this order, the priority of the non-executable level is determined. However, in the configuration example of the message flag shown in FIG.
It4 and Bit0 are unused.

Next, k is 8 in the judgment in step S57.
If を exceeds, the process proceeds to step S58, where disp_dat = 0 is set, and the di stored in the memory 102 in step S55 is set.
Referring to the data table shown in FIG. 23 from sp_dat, the display color of the print job on the menu bar is selected.
If a plurality of 1s exist in the message flag, the message flag is created again when the user's action has been taken to overcome the high-priority unexecutable level, and the next highest priority is given. It can be determined and displayed as a non-executable level.

FIG. 10 shows an example in which the result of the determination as to whether or not execution is possible is displayed on the color LCD 104.

In the display example shown in FIG. 10, the print jobs in red and yellow are not executable, and the others are executable jobs. The red display corresponds to, for example, the levels of Bit7 to Bit5 in FIG. 22, and the yellow display corresponds to the levels of Bit3 to Bit1. At this time, only the non-executable job may be displayed, or the non-executable job and its level may be displayed by shading of the fill pattern.

Next, a process for displaying a detailed explanation for an unexecutable print job will be described with reference to FIG.

FIG. 11 is a flowchart showing a processing procedure for displaying a submenu when a menu bar is touched when a list of waiting jobs is displayed.

First, in step S61, disp_dat
From the start address of the display data storage destination. FIG.
As shown in the figure, the start address of the display submenu screen data corresponding to the value of disp_dat is programmed in the memory 102 in a format that can refer to the table. Similarly, referring to the start address, the screen type, the message, the number of keys, and the in-key message are stored in the memory 102 sequentially from that address.

Next, in step S62, it is determined whether or not the obtained start address is equal to Null. If the determination results are equal, there is no submenu display, so that the display does not change. If the comparison result in step S62 is not equal, the process proceeds to step S63, and the screen type of the display data is acquired by referring to the start address acquired in step S61.

At step S64, screen data corresponding to the screen type acquired at step S63 is prepared. Then, in step S65 and step S66, step S
A message to be displayed on the screen is acquired by referring to the start address acquired in 61, and the display message is incorporated into the screen data. Then, in step S67,
After obtaining the number of keys (K) to be displayed on the screen with reference to the start address obtained in step S61, it is determined in step S68 whether the number of keys (K) is zero.

If the decision result in the step S68 is 0, there is no key to be displayed, and the process advances to a step S74.
The created screen data is displayed on the color LCD 104.
If the determination result in step S68 is not 0, step S
At 69, m = 0, and at step S70, m is set to 1
Increase (m + 1).

Next, in step S71, a message to be displayed on the key (m) on the screen is obtained with reference to the start address obtained in step S61. After incorporating this message into the display of the key (m) in step S72, K and m are compared in step S73. K
If m and m are equal, it indicates that the number of keys to be displayed is insufficient with respect to the number of keys, and the process returns to step S70 to repeat the process in order to acquire further key display data.

If K and m are equal in the comparison in step S73, it indicates that the process of incorporating the display data into the key has been completed, and the flow advances to step S74 to display the created screen data on the color LCD 104.

FIGS. 12 to 18 respectively show disp_dat
= 1, disp_dat = 2, disp_dat = 3, disp_dat =
5 shows an example of a detailed screen displayed on the color LCD 104 when disp_dat = 6, disp_dat = 7, and disp_dat = 7.

In each screen, the reason why the print job cannot be executed, that is, the contents of the level is displayed at the top of the screen, and a menu bar for selecting setting change of the print job or canceling the print job is displayed at the bottom. Is displayed.

The screens of the detailed display in FIGS. 17 and 18 show msg_dat_SIZ and msg_dat_ added to the message flag.
Based on TRY and msg_dat_TRY, the paper size (output size) to be replenished, the paper type, and the tray No. to which the paper is to be collected in the display of the top level contents Is shown. As shown in FIG. 19, such a detailed display screen may be displayed on the list screen when a print job is selected from the print job list display.

In the above detailed display, the flow of the process when the cancel of the print job is selected will be described with reference to the flowchart of FIG.

The processing of this flowchart is a flow for processing while skipping the cancel job.
In step 81, the "post-job ID" of the "job registration data of the previous job ID" is changed to "the post-job ID of the job registration data of the cancellation target", and then in step S82, the "job registration data of the post-job ID" is changed. "Previous job ID" is changed to "Previous job ID of job registration data to be canceled".

As described above, according to the present embodiment, it is possible to determine at a glance whether a print job waiting to be executed is executable or not executable. The user can take appropriate measures promptly and quickly until the image forming operation of the image forming apparatus is interrupted, thereby preventing the efficiency of the image forming operation from being reduced.
