Description

  The present invention relates to an image forming apparatus, and more particularly to display control of a display unit provided in the image forming apparatus.

  For example, in a system in which a personal computer and an image forming apparatus are communicably connected via a network, when printing a file created by the personal computer, basically, a predetermined print request operation is performed by the personal computer. Need to do. However, some recent image forming apparatuses have a so-called reprint function. The reprint function is a function that allows a reprint process to be performed only on an operation on the image forming apparatus without requiring a print request operation on a personal computer for a file that has been subjected to a print process. Specifically, the print data of each job once executed for printing is stored in a storage medium in the image forming apparatus together with the job name (for example, a file name attached). When executing the reprint function, first, job names of a plurality of jobs stored in the storage medium are displayed in a list on a display unit provided in the image forming apparatus, and a specific job name is designated therefrom. Thus, the printing process is executed for the print data corresponding to the designated job name. The reprint function includes a so-called secure print function for improving security. In this case, when a print request operation is performed on a personal computer, a file is transmitted to the image forming apparatus together with password information. However, the printing process is not executed, and the file printing process is executed for the first time only when a password is input to the image forming apparatus.

  In recent years, a large-capacity storage medium has been built in the image forming apparatus, and print data corresponding to a large amount of jobs can be stored for the reprint function. Then, as in the case of Patent Document 1, a large number of job names are displayed in a list on the display unit, and a plurality of job names having the same or similar job names may exist among them. In such a case, there is a problem that even if the display on the display unit is viewed, it is difficult to distinguish each job.

In addition, in Patent Document 1, each print data is stored in association with each user, and when executing the reprint function, a list of user IDs, dates, etc. is first displayed on the display unit. Only the job name associated with the user ID designated by the user is displayed so as to be designated. Even when this user ID is selected, the same or similar user ID exists, and even when the display on the display unit is viewed, it is difficult to distinguish them.

According to the present invention, by printing only a part (for example, the first page part) instead of the entire file, it is possible to confirm that the file specified by the user is the desired one and then perform the main printing for the entire file. Can be executed.

An embodiment of the present invention will be described with reference to FIGS.
1. Overall Configuration of Printer The printer 10 of this embodiment (an example of an “image forming apparatus”) has a PC print function for receiving print data from a host computer or a client computer (referred to as a “computer 50”) as a terminal device and printing. A direct print function for directly reading and printing image data stored in an external memory (for example, the USB memory 17 in this embodiment) is provided.

  FIG. 1 is a simplified diagram illustrating a hardware configuration of the printer 10. The printer 10 includes a print engine 11 that performs a printing operation on paper as a print medium, a display unit 12, a USB host I / F 13, a control unit 14, an operation unit 15 that is operated by a user, and a host I / F 16. An internal memory 18 is provided. A print processing area in the internal memory 18 stores a program for controlling the operation of the entire printer 10. The control unit 14 includes a CPU and controls operations of the print engine 11 and the display unit 12 based on a program stored in the internal memory 18. The printer 10 is capable of data communication with the computer 50 via the host I / F 16. The printer 10 is detachably mounted with a USB memory 17 and information in the USB memory 17 is read via the USB host I / F 13.

2. Memory structure in USB memory In the USB memory 17, a file system having a tree structure in which a plurality of directories are formed in a hierarchy is constructed, and a plurality of files (image data, text data, etc.) are, for example, user's favorite Stored separately for each folder (directory) created for each category. In the present embodiment, as shown in FIG. 2, for example, three folders (indicated by “folder 1”, “folder 2”, and “folder 3”) are stored in the USB memory 17. Of these, four PDF (Portable Document Format) format files (“file1.pdf”, “file2.pdf”, “file3.pdf”, “file4.pdf”) are stored in the folder 1. In the folder 2, one JPEG (Joint Photographic Experts Group) format file ("file5.jpg") is stored. Also, in folder 3, there are two TIFF (Tagged Image File Format) format files ("file6.tiff" and "file7.tiff"), and two printer file format files ("file8.prn" and "file9.prn"). "), A JPEG format file (" file10.jpg ") is stored.

3. Configuration of Display Unit and Operation Unit FIG. 3 is a schematic diagram showing the operation unit 15 and the display unit 12 arranged on the surface of the main body case of the printer 10. The display unit 12 is a liquid crystal display unit, for example, and has a two-screen configuration in which a first display unit 21 and a second display unit 22 are arranged vertically. The operation unit 15 includes an up / down switch 23 including an up key 23A and a down key 23B, an execution key 24, a cancel key 25, a forward key 26, and a return key 27.

  For example, when the direct print function is executed, the path name 40 indicating the position in the tree structure for the folder currently displayed (processed) is displayed on the second display unit 22. Further, the file name 41 (an example of “designated information”) in the folder is displayed on the first display unit 21 one by one in a scroll format. Then, for example, when the forward key 26 and the return key 27 are operated to move between the upper layer and the lower layer of the tree structure and the execution key 24 is pressed, it is currently displayed on the first display unit 21. A file ("file1.pdf" in FIG. 3) can be designated as a target for direct printing. In this case, a plurality of files can be designated as files for direct printing. When the designation of the target file for direct printing is completed, various printing conditions such as paper size and number of copies are set by the operation of the operation unit 15.

4). Menu Selection In the present embodiment, selection between the above-described PC print and direct print, and further, as a PC print reprint function, security print and normal reprint can be selected by operating the operation unit 15. In the security print, print data transmitted from the computer 50 is stored in the internal memory 18 as a file with a job name, for example, and an authentication password for each user associated with the print data is stored in the operation unit. 15 is a function that allows the printing process to be permitted by the control unit 14 on the condition that it is input at 15 (an example of “input unit”). At this time, the internal memory 18 is an example of a “storage medium”, and the control unit 14 functions as a “print control unit”. This is particularly useful when printing materials that require confidentiality. Note that this security print is executed once when print data is sent from the computer 50, and thereafter the print data (print data before development processing or data after development processing such as a bitmap) is displayed. Even when the configuration is stored in the internal memory 18 or when the print data is transmitted from the computer 50, the print data (the print data before the expansion process or the expansion process such as the bitmap) is not executed. The later data) may be stored in the internal memory 18. In this embodiment, the authentication password is registered in the internal memory 18 of the printer 10 in association with the user ID. However, the present invention is not limited to this, and the authentication password is set for each print request. The computer 50 may be configured to transmit the print data together with the print data.

  On the other hand, normal reprinting refers to print data (print data before expansion processing or data after expansion processing such as bitmap) transmitted from the computer 50 and subjected to print processing as a file with a job name attached to the internal memory 18. The print data is re-printed by a predetermined operation on the operation unit 15. If this function is used, the print data once printed can be reprinted by the operation of the operation unit 15 of the printer 10 without returning to the computer 50 and performing the print request operation again.

  Note that in order to use security printing or normal reprinting, it is usually necessary for the computer 50 to make settings when a print request is made. When the setting is made, a flag indicating security printing or normal reprinting is transmitted to the printer 50 together with the print data. Further, in the case of security printing, the user ID set at the time of the print request is transmitted to the printer 50 together with the print data.

  As shown in FIG. 4, the internal memory 18 stores the job name (print data file name), the print request date and time, the security print and the like for each print data transmitted from the computer 50 in the security print or normal reprint setting. A normal reprint flag is stored in association with each other. In the case of security printing, a user ID (an example of “user identification information”) is further stored in association with each other.

5. When the display menu is selected, a reprint menu (Reprint Menu) is displayed on the second display unit 22 of the display unit 12, and character strings indicating security print and normal reprint are scroll-displayed on the first display unit 21, respectively. . In FIG. 5, a character string “Secure Print” indicating a security print is displayed. Here, when the security print is selected by pressing the execution key 24, “User” is displayed on the second display unit, and each user ID is displayed on the first display unit 21 for operating the up / down switch 23. In response, the scroll display is performed one by one. In the figure, the character string "yamada" is displayed. Here, when the execution key 24 is pressed and the user ID “yamada” is selected, a message requesting input of a password is displayed on the display unit. Only when a password that matches the authentication password corresponding to the user ID is input through the operation unit 15, a plurality of job names associated with the user ID and having a security flag set are displayed as up / down switches. In response to the operation 23, the display unit 12 scrolls one by one. Of course, it may be configured to require the input of a password when specifying a job name.

  Here, as shown in FIG. 4, the user ID “yamada” stores three security print jobs (files). Therefore, when no processing is performed on the display on the display unit 21, “Job” is displayed on the second display unit 22 as shown in parentheses in FIG. In accordance with the operation of the up / down switch 23, "MYDOCUMENT.DOC", "MYDOCUMENT.DOC", and "HOUKOKU.DOC" are sequentially scroll-displayed. In this case, two job names “MYDOCUMENT.DOC” are displayed in the same way, and the two cannot be distinguished on the display.

  Therefore, in the present embodiment, the display control shown in FIG. 6 is executed. First, in S1, the control unit 14 determines the job name of the file associated with the user ID ("yamada" in the example of FIG. 5) specified by the operation unit 15 (in the example of FIG. 5, "MYDOCUMENT.DOC"). , “MYDOCUMENT.DOC”, “HOUKOKU.DOC” These are examples of “specified information group to be displayed”) from the internal memory 18. In step S2, it is determined whether there is a job name having a common character string of a predetermined number of characters (for example, 4 characters) for a plurality of acquired job names. At this time, the control unit 14 functions as an “information determination unit”. In the example of FIG. 5, two “MYDOCUMENT.DOC” and “MYDOCUMENT.DOC” are determined as common designation information.

  If the control unit 14 determines that there is common designation information (S2: Y), the attribute information (for example, the number of pages of the file, creation date and time, file format, resolution, paper size, data) of each print data (file) in S3. Volume, file creator name, etc.) are added to the job names that are designated as common designation information. In the example of FIG. 5, the number of file pages and the creation date and time are added as attribute information. Thus, the character strings displayed on the display unit 12 are “MYDOCUMENT.DOC Page: 5 09/27” and “MYDOCUMENT.DOC Page: 17 08/11”, respectively. At this time, the control unit 14 functions as a “processing unit”.

  The character string length of each job name ("MYDOCUMENT.DOC Page: 5 09/27", "MYDOCUMENT.DOC Page: 17 08/11") after processing in S4 is used as a normal job name display. It is determined whether or not the display digit of the first display unit 21 is exceeded. At this time, the control unit 14 functions as a “display determination unit”. When the character string length of the job name after processing does not exceed the display digit of the first display unit 21 (S4: N), the job name can be displayed only by the first display unit 21, so the processing is performed in S5. The subsequent job name is displayed only on the first display unit 21. At this time, the control unit 14 functions as a “display control unit”.

  On the other hand, when the character string length of the processed job name exceeds the display digit of the first display unit 21 (S4: Y), can another display area (specifically, the second display unit 22) be used in S6? If it can be used (S6: Y), the processed job name is displayed using the second display unit 22 in addition to the first display unit 21 in S5 and S7. In the example of FIG. 5, for the job name “MYDOCUMENT.DOC Page: 5 09/27”, “MYDOCUMENT.DOC” is displayed on the second display unit 22 and “Page: 5 09/27” is displayed on the first display unit 21. Is displayed. For the job name “MYDOCUMENT.DOC Page: 17 08/11”, “MYDOCUMENT.DOC” is displayed on the second display section 22 and “Page: 17 08/11” is displayed on the first display section 21.

  If the second display unit 22 cannot be used in S6 (S6: N), the common character string portion corresponding to a predetermined number of characters (for example, the number of characters protruding from the display digit) is deleted in S8. For example, the common character string portion “MYDOCUMENT.DOC” is set to “MYDO”, and further processed as “MYDO Page: 5 09/27” and “MYDO Page: 17 08/11”, respectively, and displayed on the display unit 12 (S5). . When it is determined in S2 that there is no common designation information (S2: N), the process proceeds to S4 without performing the process of S3. Even if the second display unit 22 is used in S6, even if the processed job name cannot be displayed as a whole character string, a part of the common character string portion may be deleted by the process of S8.

  In the above, the example in which the control shown in FIG. 6 is applied to the job name display has been described. However, the control can also be applied when the user ID is selected. That is, when a user ID is selected, a plurality of user IDs currently registered in the printer 10 are scroll-displayed one by one in accordance with the operation of the up / down switch 23 on the first display unit 21. There may exist a plurality of registered user IDs such as “yamada” and “yamamoto” that are very similar and confusing on the display. Accordingly, for example, the job information associated with each user ID, the number of jobs, the registration date of the user ID, and the like are added as attribute information, so that both can be easily identified. it can. At this time, as in the case of security printing, the internal memory 18 is an example of a “storage medium”.

  Also, when selecting a file to be printed for direct printing, as shown in FIG. 3, the file names of a plurality of files stored in the USB memory 17 are scrolled one by one in accordance with the operation of the up / down switch 23. The Among these plural files, there can exist files having similar file names. Therefore, by applying the control of FIG. 6, similar file names can be processed to be more identifiable and displayed on the display unit 12. At this time, the USB memory 17 is an example of a “storage medium”.

6). Advantages of the present embodiment (1) According to the present embodiment, when job names, user IDs, or file names that are the same or similar to each other exist, the respective attribute information is added. Even if job names and the like are the same or similar, there is a high possibility that their attribute information is different. Therefore, by performing processing for adding attribute information to the job name or the like and displaying it on the display unit 12, it is possible to display the job names or the like that are the same or similar to each other in a state that is visually distinguishable.

  (2) If attribute information is added, the job name or the like becomes longer by that amount, and the first display unit 21 alone may not be able to display all. Therefore, in this case, all the character strings are displayed as much as possible using the second display 22.

  (3) Even if all the character strings may not be displayed on the display unit 12, they are different from each other by applying a process of omitting a common character string portion among the same or similar job names. The character string portion is visually emphasized, making it easier to distinguish between the two.

  (4) In this embodiment, when a file to be printed is designated at the operation unit 15 during security printing or direct printing, the control unit 14 first prints a part of the file, for example, only the first page. Temporary printing to be performed by the engine 11 is executed, and then the print engine 11 is caused to execute main printing for printing all pages of the file by a main printing instruction operation in the operation unit 15. With such a configuration, there is an advantage that the main printing can be performed after confirming that the file designated by the user is a desired file by looking at the temporarily printed printing result. At this time, the control unit 14 and the print engine 11 function as a “temporary printing unit”.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) In the above embodiment, the user ID, job name, and the like are scrolled one by one on the display unit according to the operation of the up / down switch 23. However, the display area is wide. If it exists, the structure which displays several user ID etc. simultaneously may be sufficient.

  (2) In the above embodiment, when the user ID, job name, or the like cannot be displayed on the display unit 12, another display area is used or some common character string portions are deleted. However, the present invention is not limited to this. For example, in S6 of FIG. 6, a configuration may be adopted in which all character strings are displayed by scroll display in the horizontal direction or the vertical and horizontal directions only on the first display unit 21.

  (3) In S3 of FIG. 6, the configuration may be such that the print request date and date from the computer 50 are added separately from the attribute information or together with the attribute information.

  (4) In the above embodiment, only when the processed job name or the like cannot be completely displayed on the display unit 12, the processed job name or the like is partially omitted and displayed. However, the present invention is not limited to this. If there is a combination of job names and user IDs that are the same or similar to each other and are confusing, a part or all of the common character string portion is omitted regardless of whether or not it can be displayed on the display unit. May be. That is, in FIG. 6, when “Y” in S2, the process of S8 is performed instead of the process of S3 or after the process of S3. Thereby, with respect to misleading job names and the like, different character string portions are visually emphasized, and an effect of facilitating the distinction between the two is obtained.

  (5) The present invention can also be applied to a configuration in which a user name and a job name are selected and input from a plurality of user names displayed on the display unit at the time of copying in a printer having a scan function. it can.

  (6) In the above embodiment, the case where each job name or file name is displayed on the display unit 12 in order to designate a print target for security printing or direct printing has been described as an example. Needless to say, the present invention can also be applied to the case where each job name or file name is displayed on the display unit 12 in order to designate a target.

  (7) Not only user IDs and file names but also user IDs and file names are mixedly displayed on the display unit 12 and the control of FIG. 6 is executed when they are the same or similar to each other. Good.

(8) For example, when “MYDOCUMENT.DOC” is displayed on the second display unit 22, a display indicating how many files have the same job name may be added. In the example of FIG. 5, it is displayed as “MYDOCUMENT.DOC (2)”.
(9) In the above-described embodiment, the case where the same or similar job name, user ID, or file name is present and the respective attribute information is added and displayed on the display unit 12 has been described as an example. However, the present invention is not limited to this, and when the added attribute information is the same or similar to each other, another attribute information may be added.
(10) In the above-described embodiment, the display unit 21 configured by the display area divided for each row has been described as an example. However, the display unit 21 is not limited to this, and the display unit 21 is configured from the display area divided for each column. It may be configured.
(11) In the above embodiment, the example in which the display is applied for designating a plurality of files stored in the USB memory 17 as the external storage medium has been described. However, the present invention is not limited to the external storage medium, but the internal storage medium of the printer 10 You may apply to the display for the designation | designated of the some file stored in.
