2. Description of the Related Art A method of selecting output paper in a printer or a multifunction peripheral having functions such as a copying machine, a facsimile, a printer, etc. includes a paper size in which an operator specifies the size or type of paper to be printed and selects the output paper. A selection method, an automatic tray selection method in which the apparatus automatically selects paper of a size corresponding to input data, or a configuration in which an operator selects a tray containing output paper, that is, a tray number (No.) There is a method such as a tray designating method for designating and selecting a tray.

When the user wants to specify the paper quality and color of the paper, for example, by specifying the tray in which the paper to be printed is stored, it is possible to omit various specifications such as size, color, and paper quality. , if either is informed what type of paper on which the tray advance is housed, the print request by the tray specified is convenient. Many printers capable of outputting to various types of paper have a configuration in which the correspondence between the tray and the paper is set in a fixed relationship in advance, and a general user can arbitrarily change the tray. It was possible to output to desired paper by specifying a tray.

However, many multifunction devices such as printers having a copying function have a configuration in which a user can freely change trays. A problem arises when the above-described tray designation type output paper designation method is adopted in such a multifunction peripheral. That is, if a tray is replaced by a certain user, the paper is changed, copying is performed, and the user is left in the changed state, if another user issues a print job request specifying the tray, Is output on a sheet different from the output sheet expected by the user who does not know the change of the image.

For example, in a network-connected printer, when a user wants to make one print request using paper stored in a specific tray, the user designates one printer tray and sends a print job via the network. Output. If predetermined sheets are stored in the designated tray, the print job is executed without any problem. However, for example, if another user uses the network-type printer as a copying machine before executing the print job, and the tray is switched at that time, the print job is not executed when the print job is actually executed. Is output on paper different from what the user requested. Such a situation is problematic in recent multifunction peripherals, especially in network-connected printers such as LAN connections.

In order to prevent such a problem, an apparatus described in Japanese Patent Application Laid-Open No. H10-150509 discloses a multifunction machine having a copy function, a facsimile function, and a printer function.

When the job is issued, another user is warned that the paper is being used, and the user who is using the tray is notified that another user has specified the paper feed tray, and the tray is being used. The tray can be used by another user based on the confirmation of the user. In other words, a configuration is disclosed in which the occurrence of a tray designation job is notified to another user, and erroneous output is prevented by permission of use of the user.

In the configuration of the prior art as described above, the apparatus described in Japanese Patent Application Laid-Open No. H10-150509 has a configuration in which a print function and a facsimile function are prohibited. In this method, a user who is executing a job requests the other users to confirm and execute the permission to use the tray, and has a disadvantage that the job is restricted or a burden is imposed on the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a plurality of embodiments of a print processing apparatus according to the present invention will be described in detail with reference to the drawings.

[First Embodiment] FIG. 1 is a block diagram showing the configuration of a first embodiment of the print processing apparatus according to the present invention. The print processing apparatus of the present invention includes, for example, a copying function, a printer function,
This is a printing device 10 having a facsimile function.

The printing device 10 includes an arithmetic processing device 101,
Storage device 102, display device 103, paper trays 1, 10
4, paper trays 2 and 105 and paper trays 3 and 106 are provided. Although three paper trays are shown, the number of trays shown here is an example, and the number is not limited, and a configuration in which more trays can be stored may be used.

The arithmetic processing unit 101 has a function of storing paper information such as the size of paper stored in a paper storage tray and a paper change history information table in the storage device 102.
Further, it has a function of comparing the current paper size setting with the user's designation based on the change history stored in the storage device 102. In addition, it functions as a control device that controls execution of print processing based on a print job. The change history information will be described later in detail with reference to FIG. The display device 103 displays user-designated information, paper tray storage paper information, print job standby, execution information, and the like. The paper trays 1 to 3 and 104 to 106 are trays that can store various kinds of paper having different paper sizes, directions, paper qualities, colors, and the like.

FIG. 2 shows an example of a paper tray. The paper tray 20 has a configuration in which paper 202 is stored in a partition plate 201. The partition 201 can move in accordance with the size of the paper 202 to be stored, and the size of the stored paper can be identified by a position sensor that identifies the position of the partition 202. . The identified paper size information is input to the arithmetic processing unit 101 and registered in the storage device 102 as paper tray change history information as needed. Further, the arithmetic processing device 101 compares the identification information, the paper tray change history information with the tray information specified in the print job of the user, or the specified paper information.

As for the information on the type of paper in the paper tray, it is possible to directly input the paper type and the like by user input in addition to the identification information by the sensor. For example, information indicating that A4 vertical white paper is stored in the paper trays 1 and 104 and letter size OHP paper is stored in the paper tray 2 is input to the input device (see FIG. (Not shown), or input by a user from an input device via a network connected to the printing device 10 and registered in the paper tray change history information of the storage device 102 via the arithmetic processing device 101.

Hereinafter, the paper tray change history information will be described. FIG. 3 shows an example of the paper tray change history information table registered in the storage device 102. Printing device 10 of FIG.
Has three paper trays, and the storage device 102 registers individual change histories corresponding to the three paper trays 1 to 3 and 104 to 106. For example, in FIG. 3, the paper tray change history information of tray 1 is 1998.05.01.10:0:A4L 1998.05.01.10:03:B5 1998.05.01.10:07:A4L Are registered. These indicate that the tray 1 has been replaced with paper of each paper size at the date and time registered in the history. 1
At 10:00 on May 1, 998, A4L paper was stored in tray 1, and on May 1, 1998 at 10:03, B5
Sheets are stored in Tray 1 on May 1, 1998,
0:07 indicates that A4L paper is stored in the tray 1. Note that L after A4 indicates a vertical direction (S is a horizontal direction). Here, the latest history information corresponds to the current paper size.

In the paper tray change history information, the time information is set based on the time information from a timer (not shown) provided in the printing apparatus, and the paper size information is the paper size information (from each tray). The arithmetic processing device inputs the paper size (identified by the position identification by the sensor of the partition plate described in FIG. 2) and registers it in the storage device as needed. When the user stores predetermined paper, for example, color paper in the tray, the stored paper information can be directly input and registered as paper tray change history information. Although the paper tray shown in FIG. 2 has a configuration capable of only identifying the size, the color of the paper and other types of paper are identified by installing various sensors such as a color sensor, and the identification information is obtained. It is also possible to register as paper tray change history information. In summary, either information identified by the sensor or information obtained by user input can be registered as paper tray change history information.

The display device 103 shown in FIG. 1 displays the latest history information of the current tray, and displays the type of paper currently set in the tray. Therefore, after confirming the current paper type, the user can execute various functions such as copying and printing.

FIG. 4 shows an operation flow of the print processing apparatus of this embodiment. Hereinafter, the flowchart of FIG. 4 will be described in detail.

First, step 401 is a step in which a user who intends to execute printing instructs a print processing apparatus to issue a job processing request. Print job instructions
This can be performed directly to the print processing apparatus or from a client apparatus connected to the print processing apparatus via a network. In step 402, a job is generated and a job is accepted in accordance with a job instruction from the user. At this time, the arithmetic processing device of the print processing device accepts the job with the job acceptance time corresponding to the job.
The job reception time can be received by the client in association with the job, or the arithmetic processing unit can use the timer of the print processing unit to associate the time with the job. . When the job reception ends, the job is started in step 403.

In step 404, it is determined whether the received job is a tray designation job. For the job, instead of specifying the output tray, the job that directly specifies the paper size, or automatically finds the appropriate paper size from the document (image) size and magnification, and automatically sets the tray that stores paper of the appropriate paper size There are various jobs such as an automatic tray selection job to be selected. In these cases, it is determined that the job is not a tray designation job (determination of step 404: No), and the process proceeds to step 405, where processing is executed as a job in which a paper size is designated. Is done. In step 406, an appropriate tray is selected according to the size specified, and in step 407, printing processing is performed on the paper in the selected tray.

On the other hand, for example, when the user sends a print job specifying the paper output of the tray 1 to the printing apparatus, it is determined in step 404 that the job is a tray specification job (the determination in step 404 is Yes). In this case, the processing shifts to the processing of the tray designation job after step 408. In step 409, the tray specified for the job is selected. Next, the process proceeds to step 410, where the paper information is acquired from the paper tray change history information based on the time information associated with the requested job.

In step 411, the current paper information based on the paper information acquired from the paper tray change history information, that is, the tray storage paper at the time of job reception and the current paper storage tray at the time of job execution, is used. It is determined whether the sheet size of the sheet is different from the sheet at the job receiving time. If the current tray storage paper and the storage paper of the tray storage paper at the time of job reception are the same, the step 40
Proceed to 7 to execute printing.

If the current tray storage paper and the storage paper of the tray storage paper at the time of job reception are different, the process proceeds to step 412 to interrupt the printing process. At this time, a warning notifying that the sheet size at the time of accepting the job is set on the tray is displayed on the display device 103.

According to the above configuration, it is possible to prevent an erroneous printing process when the sheets stored in the tray are different between when the job is received and when the job is executed. That is, when a user issues a print job and the printing apparatus is planning to output to the storage paper in the storage tray at the time when the printing apparatus receives the job, and then, when the storage paper is replaced by another user's tray replacement. However, the replacement can be known at the time of job execution, and no erroneous printing process occurs.

In the above-described embodiment, the comparison is made between the sheet stored in the tray at the start of the job processing and the sheet stored in the tray at the time of accepting the job. 1 sets standard paper as default tray storage paper such as A4 portrait and tray 2 as B5, compares the default paper with the current tray storage paper, and displays a warning when there is a difference between them. May be configured.

[Embodiment 2] FIG. 5 shows an embodiment in which the print processing apparatus of the present invention is connected to a network. In FIG. 5, a printing apparatus 500 is a print processing apparatus having, for example, a copy function, a printer function, and a facsimile function, as in the first embodiment. The printing device 500 includes an arithmetic processing device 50.
1, a display device 502, paper trays 1 and 503, paper trays 2 and 504, and paper trays 3 and 505. On the other hand, the client device 5 connected to the network
11 has a storage device 511 for storing various information. Although not shown, the printing device 500 and the client device 511 have input / output means for mutually executing input / output of various information.

The arithmetic processing unit 501 notifies the client device 510 of paper information such as the size of paper stored in the paper storage tray and paper change history information via the network. In addition, it functions as a control device that controls execution of print processing based on a print job. The display device 502 displays information specified by the user, stored paper information of a paper tray, print job standby, execution information, and the like. The paper trays 1 to 3 and 503 to 505 are trays that can store various types of paper having different paper sizes, directions, paper qualities, and colors. These trays have the same configuration as that described in the first embodiment.

The client device 510 includes the storage device 51
1 and from the arithmetic processing unit 501 of the printing device 500,
The paper information such as the paper size stored in the paper storage tray and the paper change history information are received and stored in the storage device 511.

As for the paper information in the paper tray, not only the identification information by the sensor but also the paper type information can be input by the user as in the first embodiment.
For example, paper trays 1 and 503 have A4 portrait white paper, and paper trays 2 and 504 have letter size OHP.
An input device (not shown) attached to the printing device 500 as information indicating that paper is stored as tray storage paper information;
Alternatively, the information can be input from an input device via a network connected to the printing device 500, and the paper tray information can be output from the arithmetic processing device 501 of the printing device 500 to the client device 510 and stored in the storage device 511. .

Storage device 511 of client device 510
Receives paper information such as the paper size stored in the paper storage tray from the printing apparatus and stores it. This paper information
Although the paper tray change history information shown in FIG. 3 described in the first embodiment may be used, only the latest tray information may be used. The latest history information corresponds to the current paper size. Further, the sheet information stored in the storage device 511 is stored in the client device 51.
It may be configured to display 0.

FIG. 6 shows an operation flow of this embodiment. Hereinafter, details of each step of the flowchart of FIG. 6 will be described. In the flow of FIG. 6, steps 601 to 604 are processing steps on the client side.
The following are the processing steps on the printing device side.

For example, a process in which a user who wants to execute printing while viewing the paper information such as the paper size stored in the paper storage tray of the client device 510 instructs and transmits a job processing request to the printing apparatus is performed in step 601. ６０604. A job instruction (step 601) by the user is executed, and it is determined in step 602 whether or not the instruction job is a job specifying a tray. If the job is a tray designation job, a process of adding paper size information of the printing device to the job information transmitted to the printing device in step 603 is performed. Note that the printing apparatus 500 previously outputs the sheet identification information for each tray to the client device 510. Based on the received sheet information, the client side adds the sheet size information to the tray designation job in step 603. Generate

In this flow, to simplify the description, an example is shown in which only the paper size is added as information. However, as in the first embodiment, the printing apparatus 500 performs size discrimination by the position sensor of the partition plate, Identify paper color and other paper types by various sensors such as color sensor,
These identification information can be obtained as paper tray information, or information obtained by user input can be obtained as paper information, and processing based on these various paper information is also possible. Therefore, the various types of information may be transferred between the print processing device and the client device.
The job to which the paper size information has been added in step 603 is transmitted to the printing apparatus in step 604. If the determination in step 602 is No, that is, if the job is not a tray designation job, the flow advances to step 604 without executing the sheet information adding step in step 603, and the job is transmitted to the printing apparatus.

In step 605, the printing apparatus receives a tray designation job from the client. Upon receiving the job, the printing apparatus starts a print job (step 606), and determines in step 607 whether the received job is a tray designation job. If the job is not a tray specification job but directly specifies a paper type, it is determined that the job is not a tray specification job (determination of step 607: No), and the process advances to step 611 to specify a paper type, for example, a paper size. The processing as a completed job starts. In step 612, an appropriate tray is selected according to the specified paper size. Further, in step 613, a printing process is performed on the sheet on the tray selected.

On the other hand, it is determined in step 607 that the job is a tray designation job (the determination in step 607 is Yes).
Then, the processing shifts to the processing of the tray designation job after step 608. In step 608, a tray specified for the job is selected. Next, the process proceeds to step 609, where it is determined whether the sheet size currently stored in the designated tray and the sheet size information designated for the print job match.

There may be a time difference between the time when the client generates the print job and the time when the job is actually executed. During this time, when another user changes the tray of the printing apparatus and executes copying. In some cases, the paper size currently stored in the specified tray may not match the paper size specified for the print job. If such a mismatch is determined in step 609, the process proceeds to step 610, and the printing process is interrupted. During this interruption,
The screen is displayed so that sheets of the sheet size set for the job are stored in the tray designated by the job. In this case, not only the display on the display device 502 of the printing device 500 but also the output on the display means (not shown) of the client device 510 may be performed.

The transmission of the sheet information from the printing apparatus to the client may be performed in response to a request from the client, or may be performed at any time when the tray replacement is identified. Step 603
The paper information adding step of the tray designation job is performed on the client side, but may be performed on the printing apparatus side when a print job is received.

According to the configuration of the present embodiment, the client can obtain the latest tray storage paper information from the printing apparatus via the network, and the client can perform the print job specifying the tray and paper size according to this information. Can be issued. Further, if the sheet at the time of job designation is different from that at the time of execution, that fact is notified, so that the wrong sheet is not output.

Third Embodiment A third embodiment will be described as another embodiment of the print processing apparatus according to the present invention.
The system configuration of the third embodiment is the same as that of FIG.
Alternatively, any of the network configurations of FIG. 5 described in the second embodiment may be used.

In this embodiment, the type of paper to be stored in each of the plurality of trays of the printing apparatus is uniquely determined, and this is determined in advance by a tray number (No.) It is stored as a type table. FIG. 7 shows an example of this table. In FIG. 7, A4
L, A4S in tray 2 and A3S in tray 3 are set as sheets. In general, paper is rarely replaced in a printer-dedicated device, and printing based on the paper information in these tables does not cause many problems.However, in a printer having a copying function, a user can remove paper in a tray at the time of copying. May be replaced,
In such a case, a problem occurs. The present embodiment is configured to compare the stored data of the table with the paper of the tray identified at the start of the job to execute the printing process or to instruct the tray to be replaced, thereby preventing output to the wrong paper. Can be.

FIG. 8 shows an operation flow of this embodiment. Step 801 is a step in which a user who wants to execute printing instructs the print processing apparatus to issue a job processing request. The print job can be instructed directly to the print processing apparatus or from a client apparatus connected to the print processing apparatus via a network. Step 80
In 2, the job is generated and the job is accepted in accordance with the job instruction by the user. When the job reception ends, the job is started in step 803.

Next, in step 804, it is determined whether the received job is a tray designation job. If it is determined that the job is not a tray designation job (determination of step 804: No), the process proceeds to step 805, and processing of the job for which the paper size is designated is started. In step 806, an appropriate tray is selected according to the specified size. Further, in step 807, a printing process is performed on the paper on the selected tray.

On the other hand, it is determined in step 804 that the job is a tray designation job (the determination in step 804 is Yes).
Then, the processing shifts to the processing of the tray designation job from step 808. In step 809, a tray specified for the job is selected. Next, proceeding to step 810, a determination is made as to whether the job is a printer job.
If the job is not a printer job, the process proceeds to step 807, where printing processing is performed on the paper in the selected tray. This process is, for example, a process in which a user performs copying, and includes a copying execution process after checking a tray. On the other hand, if it is determined in step 810 that the job is a printer job, the flow advances to step 811 to record the paper size currently stored in the designated tray and the table (for example, the table in FIG. 7) stored in the storage unit. The paper size information is referred to to determine whether or not the obtained paper size information matches.

Before or after the client issues a print job, if another user replaces the tray of the printing apparatus and performs copying, for example, the paper size currently stored in the designated tray and the size recorded in the table are recorded. Paper size may not match. If such a mismatch is determined in step 812, the process proceeds to step 813, and the printing process is interrupted. At the time of this interruption, a screen is displayed so that sheets of the sheet size set for the job are stored in the tray designated by the job. In this case, if the configuration is of a network type, the information is displayed not only on the display device of the printing device but also on the display means of the client device. If the determination in step 812 is Yes, that is, if the paper size currently stored in the specified tray and detected by the detection unit matches the paper size recorded in the table, printing is performed in step 807 using the paper in the specified tray. To start.

According to the configuration of the present embodiment, in a device using a fixed tray storage sheet as a printer, the client can transfer the sheet information of the printer even if the user changes the tray by copying or the like. Based on the stored tray type sheet type table, comparison with the current tray sheet can be executed, printing can be performed on the correct sheet, and there is no output on the wrong sheet.

[0056]

As described above, according to the print processing apparatus of the present invention, when a sheet stored in a tray corresponding to a tray designated at the time of execution of a print job by tray designation is different from the expected one. This is notified so that the print job is not executed, so that output to an erroneous sheet can be prevented.

Further, according to the print processing apparatus of the present invention, the client who has requested the print job can obtain the current paper information, so that when the tray is specified, the paper output not intended by the user is specified. This can be prevented beforehand.
