Description

  The present invention relates to an image forming apparatus and a program.

In the office environment, there are many opportunities to print important information.
In a printing apparatus as an image forming apparatus having a general printing function, there is no time to reach a user as a print job executor from the self-seat to the printing apparatus after the printing apparatus has executed printing. In the meantime, the printed matter is exposed to the eyes of others, so it lacks security.

  Therefore, when a user prints high-security data using a printing device such as a printer, the security printing function enables the user to start printing only after the user goes to the installation location of the printing device and performs an authentication operation on the printing device. It has been known.

  However, the security printing function in a normal printing apparatus has a problem that a waiting time occurs in front of the printing apparatus because printing is not started until the user on the printing apparatus is authenticated. In particular, when a large amount of printing is performed, since the security cannot be taken into consideration, the printing waiting time is more generated.

FIG. 8 is a configuration diagram of a normal security printing machine.
The security printing machine shown in the figure includes a control unit 001, an operation panel unit 009, a user authentication unit 010, a printer unit 011, a paper discharge tray A012, a paper discharge tray B013, a lockable paper discharge tray C014, and a lockable paper discharge tray. D015.

  The control unit 001 includes a print data generation unit 002, an image processing unit 003, a memory 004, an SCN (scanner) IF (interface) 005, a LAN (local area network) IF006, a USB (universal serial bus) IF007, and a fax (facsimile). It consists of IF008.

The control unit 001 is a main control unit related to printing such as image data reception, image processing, print data generation, and memory.
The print data generation unit 002 is a circuit that converts image data stored in the memory and transmits the converted image data to the printer unit.
The image processing unit 003 is a circuit that inputs data from each IF and performs image processing such as compression / decompression / magnification / rotation.
The memory 004 is a circuit used as a storage center for temporary storage during data processing and holding of setting information.
The SCN IF 005 is an IF unit with the scanner, and is a circuit that inputs copy image data and the like.
The LAN IF 006 is an IF unit with a network, and is a circuit that inputs network print image data and the like.
The USB IF 007 is an IF unit with the USB, and is a circuit that inputs USB print image data and the like.
A FAX IF 008 is an IF unit with a FAX, and is a circuit that inputs FAX image data and the like.
The operation panel unit 009 is a UI (user interface) and is a circuit having a display display function and a key input function.
The user authentication unit 010 is a circuit having a user authentication control function.
The printer unit 011 is a circuit that receives image data from the control unit and actually prints it.
The paper discharge trays 012 and 013 are paper discharge units from which printed paper comes out.
The paper discharge trays 014 and 015 are lockable paper discharge trays.

  In the office environment, there are many opportunities to print important information. Two commonly used techniques for the flow of security printing in which a user prints high security data will be described.

<Pattern 1>
FIG. 9 is an example of a control flow diagram of a normal security printing machine.
In the figure, the control subject is a control unit 001.
In the figure, for example, when performing network printing from a user's PC (personal computer), the user issues a print job from the PC (S001), and the image data is input to the control unit 001 via the LAN IF006. . An image processing operation (for example, 1/2 magnification) is performed in the preset image processing unit 003 (S002), and the processed data is stored in the memory 004 (S003).

The user authentication unit 010 determines whether or not the user authentication is OK. If the user authentication is not possible, the user authentication unit 010 waits for the authentication result (S004 / N).
If there is no problem in user authentication (004 / Y), the print data generation unit 002 generates print data by converting the data to be transmitted to the printer unit 011 (S005), and transmits the print data to the printer unit 011. (S006).
The printer unit 011 performs printing based on the print data (S007), and discharges the printed paper to the discharge tray 012 or the discharge tray 013 (S008).
The user removes the printing paper (S009), and the print job is completed.
It should be noted that the timing of authentication does not matter, for example, the part through the matching of the user authentication unit 010 is performed in front of the image processing unit 003.

  However, in the case of pattern 1, since printing can be started only after an authentication operation is performed on the printing apparatus, there is a problem that a long print waiting time occurs.

<Pattern 2>
FIG. 10 is another example of a control flow diagram of a normal security printing machine.
In the figure, the control subject is a control unit 001.
In the figure, the user issues a print job from the PC (S010), and the image data is input to the control unit 001 via the LAN IF006.
An image processing operation (for example, ½ scaling) is performed in the preset image processing unit 003 (S011), and the processed teledata is stored in the memory 004 (S012). When printing this data, the print data generation unit 002 converts the data into data for transmission to the printer unit 011 (S013) and transmits the data to the printer unit 011 (S014).
The printer unit 011 executes printing (S015), and discharges the printed sheet to the lockable discharge tray 014 or the lockable discharge tray 015 (S016).
At the place where the printing apparatus is installed, the user authentication unit 010 performs user authentication, determines whether the user authentication is OK, and if the user authentication is not successful, waits for the authentication result (S017 / N ).
If there is no problem in user authentication (S017 / Y), the key is unlocked and the printed matter can be taken out (S018).

  However, in the case of pattern 2, there is a problem that if the lockable paper discharge tray is not empty, printing can be started only after an authentication operation is performed by the printing apparatus, so that a long print waiting time occurs.

Therefore, various proposals have been made in order to solve the above problems (for example, see Patent Document 1).
Japanese Patent Application Laid-Open No. 2004-228620 has a lockable discharge tray with a lock and a lockless discharge tray for the purpose of shortening the printing waiting time when a highly confidential document is printed on a lockable discharge tray. Is discharged to the lockable paper discharge tray, but if the lockable paper discharge tray is not empty, printing is performed on the lockless paper discharge tray after user authentication on the printing device. A technique for shortening is disclosed.

However, the technique described in Patent Document 1 cannot solve the problem that a print waiting time occurs.
SUMMARY OF THE INVENTION An object of the present invention is to provide an image forming apparatus and a program that can ensure high security and reduce a printing waiting time.

It has a function to supply. The scanner 500 has functions necessary for copying, and the operation panel 600 has an LCD 601 capable of display display and a button 602.

  The printed paper is discharged to one of the paper discharge trays 700a to 700g, and the printing paper is fed from the paper feed tray 800.

  Next, examples of the present invention will be described.

FIG. 1 is a configuration diagram of a security printing machine showing an embodiment of an image forming apparatus according to the present invention.
A security printing machine as an image forming apparatus has a configuration in which a user authentication unit and a lockable paper discharge tray are deleted from the configuration of a normal image forming apparatus, and a printing time calculation unit 100 is added instead.

In the printing operation unit 100, the arrangement of seats in the office or the like is stored in advance in the memory 004 of the printing machine, the distance between the print job person and the printing machine, and the execution time of the printing job are calculated, and the printing job starts. It has a function that can calculate how long the printing will be completed later.
With this function, the print job executor can reduce the user authentication operation time in front of the printing press and the waiting time for print processing.

FIG. 2 is an example of a control flow diagram of security printing.
In the figure, the control subject is the controller 100.
When the print job executor executes the job (S101), the printing press retrieves the data of the arrangement of seats such as offices stored in advance from the memory 004, and calculates the distance between the print job executor and the printing press (S102). ), An arrival time Ta required for the print job person to reach the printing press from his seat is calculated (S103).

For example, assuming that the speed at which the print job executor walks is 4 km / h, the distance between the print job clerk and the printing press is 20 m, and printing data with a printing time of 30 sec is to be printed, the arrival time Ta is (print The time required to reach Ta = 20 / (4000/3600) = 18 sec.
Thus, it can be calculated that the print job person can come from his seat to the printing machine in 18 seconds.

Also, the print time Tb from the start of the print job to the completion of the printed matter discharge is
Tb = (Printing time)
Tb = 30 sec
Thus, it can be calculated when printing is completed in about 30 seconds (S104).

Therefore, if the print job executor waits for 12 seconds (printing time Tb−arrival time Ta) after starting the printing job at his / her desk and goes to the printing machine, the time for leaving the printed material is eliminated. Since the printed material can be taken out without waiting unnecessarily, it is preferable to display (notify) this 12 sec on the PC screen of the print job executor, for example, using a network (S105).
Since the printing machine has a negative arrival time Ta-printing time Tb, it takes more time to process the print job than the time it takes for the print job person to go to the printing machine. (S106).
The print job itself is the same as the conventional printing method.
Here, when the relationship between the arrival time Ta and the printing time Tb is opposite to the above, the printing machine starts printing after waiting for the printing time Tb−the required time Ta, and immediately prompts the print job executor to Display on the PC that you will be picking up the printed material. The printing machine discharges the printed matter to the discharge tray (S107), and the print job person takes out the printed matter from the discharge tray of the printing press (S108).

With the above control, the print job executor can perform printing with high security without causing a user authentication operation or a print waiting time in front of the printing press.
The time until the user takes a print job is displayed on the PC screen of the user who submitted the print job.
In addition, for further security improvement, when the printed matter is left in the paper discharge tray, the name of the person executing the print job is displayed on the operation panel unit 009 so that the people around it can call attention. Is possible.

FIG. 3 is a configuration diagram of a security printing machine showing another embodiment of the image forming apparatus according to the present invention. In addition, the same code | symbol was used for the member similar to the Example shown in FIG.
The embodiment shown in the figure has a configuration in which a position detection unit 200 is added to the configuration of the first embodiment.
That is, the security printing machine as an image forming apparatus shown in FIG. 1 includes a control unit 001, an operation panel unit 009, a printer unit 011, a paper discharge tray A012, and a paper discharge tray B013 connected to a user PC. .

  The control unit 001 includes a print data generation unit 002, an image processing unit 003, a memory 004, an SCN IF005, a LAN IF006, a USB IF007, a FAX IF008, a printing time calculation unit 100, and a position detection unit 200.

  The position detection unit 200 has a function (for example, GPS (Global Positioning System)) that can detect position information for each user's PC using a wireless LAN or the like.

The control flow diagram is not different from the control flow diagram of the first embodiment, but the processing in S102 (detects the position of the print job executor) is different.
In the second embodiment, since the information of the PC on which the print job has occurred can be detected by a wireless LAN or the like, there is no need to store the information in the memory in advance as in the first embodiment. There is no need to update.

  With the above control, the print job executor reduces the user authentication operation time in front of the printing press and the waiting time for the printing process even when printing from a notebook PC, not from a fixed seat (self-seat) or desktop PC. be able to.

FIG. 4 is a configuration diagram of a security printing machine showing another embodiment of the image forming apparatus according to the present invention.
The security printing machine as an image forming apparatus shown in the figure has a configuration in which a flow line calculation unit 300 and sensors 301 and 302 installed in a paper discharge tray are added to the configuration shown in the first embodiment.

  That is, the security printing machine as the image forming apparatus shown in the figure includes a control unit 001, an operation panel unit 009, a printer unit 011, a paper discharge tray A012, a paper discharge tray B013, and sensors 301 and 302 connected to a user PC. Have

The flow line calculation unit 300 (see, for example, Japanese Patent Application Laid-Open No. 2002-245496 and Japanese Patent Application Laid-Open No. H8-267782) allows the user who executed the print job to load the sheet of the printing machine after the start of the print job. By recording the history of whether or not the user has picked up, the user has a function of correcting the calculation formula for the time from execution of the print job to picking up the printed matter.
Sensors 301 and 302 are sensors (e.g., reflective optical sensors) that detect the presence or absence of paper, and have a function of feeding back to the flow line calculation unit 300 the time until the print job executor comes to pick up printed matter from his / her seat. Have.

Although the control flow diagram is the same as that in the first embodiment, the processing in S103 (calculation of the arrival time Ta required for the print job executor to reach the printing press) is different.
In the third embodiment, attention is paid to the flow line of the print job executor. Depending on the individual, the speed of walking and the time from printing to the time when the user takes the printed material are different, so in order to calculate the time Ta more accurately, the flow line detection unit 300 and the sensors 301 and 302 are provided. It is added.
In addition, after a certain period of time, if the printed matter is left in the discharge tray A012 or the discharge tray B013 (which can be detected by the sensors 301 and 302 on the discharge trays 012 and 013), the print job executing person's PC It has a function to display that it will take a printed matter.

  With the control described above, individual differences among print job performers can be eliminated and a more accurate arrival time Ta can be calculated. Therefore, user authentication operation time in front of the printing press and waiting time for print processing can be reduced.

FIG. 5 is a configuration diagram of a security printing machine as another embodiment of the image forming apparatus according to the present invention.
The configuration of this embodiment is a configuration in which a security level determination unit 400, a user authentication unit 010, and lockable paper discharge trays 014 and 015 are added to the configuration of the first embodiment.

  That is, the security printing machine as the image forming apparatus includes a control unit 001, an operation panel unit 009, a user authentication unit 010, a printer unit 011, a discharge tray A012, a discharge tray B013, a lockable discharge unit connected to a user PC. It has a paper tray C014 and a lockable paper discharge tray D015.

  The control unit 001 includes a print data generation unit 002, an image processing unit 003, a memory 004, an SCN IF005, a LAN IF006, a USB IF007, a FAX IF008, a printing time calculation unit 100, and a security level determination unit 400.

The security level determination unit 400 is set by a print job executor when a print job is executed, and the printing press has a function of changing the printing method according to the set security level.
The user authentication unit 010 has a function for a print job executor to perform an authentication operation on the printing press.
The lockable paper discharge tray C014 and the lockable paper discharge tray D015 are locked until the print job executor authenticates on the printing press, and has a function of unlocking after authentication.

FIG. 6 is a control flow diagram of security printing as another embodiment of the image forming apparatus according to the present invention.
In the figure, the control subject is a control unit 001.
The print job executor first sets the security level (S402).
After that, when the job is executed (S403), the printing machine calls the pre-stored office layout data from the memory 004 and calculates the distance between the print job person's seat and the printing machine (S404). The time Ta required for the print job person to come from his seat to the printing press is calculated (S405).
The printing press also calculates the printing time Tb (S406), notifies the job executor's PC, etc. to pick up the printed matter after Tb-Ta has passed (S407), and the printing press waits for the Ta-Tb time. Printing is started (S408).
As in the first embodiment, when Ta-Tb or Tb-Ta is negative, printing is executed immediately.
After printing, it is determined whether or not the security level is “high”. If the security level is “high” (S409 / Y), the printed matter is placed in the lockable discharge tray C014 or the lockable discharge tray D015. Discharge (S410). If the security level is not "high" (S409 / N), the printed matter is discharged to the normal discharge tray A012 or discharge tray B013 without a key (S412). The user authentication unit 010 determines whether or not the user authentication is OK. If the user authentication is not OK (S411 / N), the process waits. If OK, that is, if the print job executor performs an authentication operation on the printing press, there is no problem (S411). / Y), the print job operator can unlock and take out the paper (S413).
If the security level is “medium” after printing (S409 / N), the printed material is discharged to the normal paper discharge tray A012 or paper discharge tray B013 without a key (S412), and the user as the print job user removes the paper. It can be taken out (S413).

Here, security levels "high", "medium", and "low" will be described.
“Medium” is the level of documents that do not care much about security (for example, confidential documents), and “High” is the level for documents that emphasize security (for example, confidential documents that can only be viewed by certain people within the company). “Low” is a level of a document that does not require security (for example, printing of net information).

  With the above control, the print job executor can take out the paper and execute the authentication process with the lockable paper discharge tray almost simultaneously with the discharge of the printed matter, so that “higher security printing”, “print waiting time” Security printing is possible.
