Abstract

PURPOSE:To prevent the division of a same job output list and the overlapping of different job output lists by detecting the movement of the stacker position via an operator intervention, judging whether the same job is continued or not, and automatically correcting the tray position. CONSTITUTION:A detecting means 31 monitors the change of the position of a stacker 30 via the interruption if execution. When a change is detected, a correcting means 32 corrects the position of the stacker 30 based on whether the job at the time of restart is a continued job or a new job. If it is the continued job, the position of the stacker 30 is returned to the original position, if it is the new job, the operation is restarted with the stacker 30 left at this position.

[Industrial application field]

The present invention relates to a method for correcting the stack position of output sheets in an output device.

For output devices such as cut-sheet printing devices that continuously execute multiple print jobs, an offset stack is used that shifts the tray serving as a stacker left and right to create a difference in the storage position of cut-sheet output sheets (hereinafter referred to as output list). method is adopted.

In this offset stack method, if the stack position changes due to operator intervention when an error occurs,
Depending on the job at the time of restart, the output list of the same job may be divided, or the output lists of multiple jobs may overlap.

Therefore, there is a need for a stack position correction method for output sheets that corrects movement of the stack position due to operator intervention or the like.

[Prior art and problems to be solved by the invention] FIG. 5 is a perspective view of a printing device, and FIG. 6 is a diagram illustrating the problem.

The printing device shown in FIG. 5 is connected to a data processing device and is configured to continuously process multiple print jobs.
Before starting the next job, a shift command for the tray is issued, and the tray is shifted to the left or right with respect to the paper discharge port 11.

If an error such as a jam occurs during execution of a series of print jobs, the operator will intervene and remove the cause of the error before restarting, but when restarting, the position of tray 1 will be in its initial state (right side). ), as shown in Figure 6 (1), if the stack position of the job in which the error occurred is on the opposite side (left side in the figure) from the initial state, the position of tray l is However, if you continue to restart job ■, the output list will be separated.

Furthermore, as shown in FIG. 6 (II), when an error occurs and tray 1 is shifted when job ■ is finished, and a shift command for tray 1 is output at the start of job ■, tray 1 is Job■ and Job■ will be shifted to the opposite side
The output lists overlap.

As described above, when the operator intervenes and shifts tray 1, there is a problem that the output list may be separated or overlapped depending on whether the job is a continuation or a new job at the time of restart.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a stack position correction method for output sheets that corrects movement of the stack position due to operator intervention or the like.

[Means to solve the problem]

In order to achieve the above object, the output paper stack position correction method of the present invention, as shown in FIG. When the change in the position is detected by the detection means 31,
A correction means 32 is provided for determining whether the job after restarting is a continuation from the previous time or a new job and correcting it to the corresponding position.

[For production]

The detection means 31 monitors the change in the position of the stacker 30 due to the interruption of execution, and when the change is detected, the correction means 32
The position of the stacker 30 is corrected depending on whether the job at the time of restart is a continuing job or a new job.

That is, if it is a continuing job, the stacker 30 is returned to its original position, and if it is a new job, it is restarted at the same position.

As described above, even if the position of the stacker 30 changes due to the occurrence of an error, separation of output lists of the same job and overlapping of output lists of different jobs can be avoided.

〔Example〕

Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a configuration diagram of one embodiment, FIG. 3 is a correction processing flowchart, and FIG. 4 is a correction process explanatory diagram.

In this embodiment, the next position (right or left) of tray l (corresponding to stacker 30) that is issued and updated at the start of a job.
Next position information 8 (hereinafter referred to as next position) indicating the next position is provided and held until updated at the start of the next job. Then, when the current position≠next position and a movement command is issued, the tray 1 is moved to the next position.

Therefore, if the current position of tray 1 changes due to interruption, the current position≠next position, and if the job is continued when restarted, tray 1 is returned to the next position, that is, the original position.

Furthermore, if the job at the time of restart is new, the next position is updated, so the current position minus the next position, and the job is restarted in that state. Note that even in normal conditions, movement processing is performed based on the current position≠next position.

In FIG. 2, l is a tray that is moved to the right or left by the moving mechanism 10.

A sensor 2 detects the current position of the tray l.

3 is a print processing unit that executes print processing for a series of print jobs and updates the next position information 8 before starting the job;
The tray position movement flag 9 is turned on and the stacker control unit 5
Start.

4 is an error handling unit, which is activated during restart processing and is
When a change in position is detected, after updating the current position information 7, the tray position movement flag 9 is turned on and the stacker control unit 5 is activated.

5 is a stacker control unit which, when the tray position movement flag 9 is on, performs movement processing based on the next position information 8 if the current position information 7 is ≠ the next position information 8, and changes the current position information based on the response result of the sensor 2. Update 7.

Reference numeral 6 denotes a memory, which has an area for storing current position information 7 primary position information 8° and a tray position movement flag 9.

7 is current position information, which represents the current position detected by the sensor 2.

8 is the next position information mentioned above.

Reference numeral 9 denotes a tray position movement flag as a movement command, and when it is on, the stacker control unit 5 performs movement processing.

10 is a moving mechanism for the tray 1.

Note that the detection means 31 includes the error processing section 4 and the correction means 32.
corresponds to the stacker control section 5.

In the above configuration, processing when an error occurs will be explained with reference to FIG.

(1) When the process is interrupted and restarted due to an error occurrence, etc., the error processing unit 4 detects whether or not there is a change in the tray position, and when a change is detected, corrects the current position information 7 and then sets the tray position movement flag 9. turn on.

(2) If the restarted job is new, the print processing unit 3 updates the next position information 8 and turns on the tray position movement flag 9.

(3) When the tray position movement flag 9 is turned on, the stacker control unit 5 executes movement processing, and if the current position ≠ the next position,
Since the job at restart is a continuation, after performing the tray movement process according to the next position information 8 (undoing), turn off the tray position movement flag 9, and if the current position = next position, the previous job has finished and the next Since the position information 8 has been updated, the tray position movement flag 9 for performing movement processing is turned off.

(4) Restart the print process, update the next position information 8 each time one job is finished and start the next job, and turn on the tray position movement flag 9 each time.

As a result, the stunning force control unit 5 performs a shift process because the current position≠next position.

As described above, an error can be prevented by a simple method of retaining the next position information 8 that instructs the moving direction of the tray 1, and when the current position changes, correcting the current position information 7 and activating the stacker control unit 5. The stack position can be modified according to the job.

Figure 4 shows the state of position correction due to the occurrence of an error based on the above processing. In (1), when an error occurs during the execution of job ■ and tray l is moved, job ■ ends. Since the next position information 8 remains the same as before,
This indicates that it will be returned to its original position and restarted. In addition, (II) indicates that the position of tray l moves, but since the next position information 8 for the next job has been updated, the current position - next position will be changed, and the process will be restarted at the same position. There is.

As described above, even if the tray position moves due to an error or the like, it is corrected according to the job, so it is possible to prevent splitting and overlapping of output lists.

〔Effect of the invention〕

The present invention provides a method for correcting the tray position of a cut sheet type output device, which detects movement of the stack position due to operator intervention, determines whether the same job is to be continued, and automatically corrects the tray position. This has the effect of preventing splitting of the output list and multiplication of different job output lists.
