Description

  The present invention relates to an image forming apparatus and program capable of performing personal authentication using an IC card.

Some image forming apparatuses of this type include a storage device (for example, an HDD). Data transmitted from a client PC can be stored in the HDD, and the stored data can be printed.
This HDD is configured to be able to store a large amount of data for a long period of time, and with the increase in the amount of information in recent years, cases of storing data in the HDD are increasing.

On the other hand, there is an image forming apparatus having functions such as user restriction and private printing, and security is enhanced.
Specifically, the user restriction function restricts the use of the image forming apparatus according to the department or job title, and the private printing function prevents forgetting to take a printed matter and prevents information leakage.

  In order to use an image forming apparatus having these functions, personal authentication using an IC card is required (see, for example, Patent Document 1). Specifically, when an IC card holder is authenticated by inserting the card into a card reader, the image forming apparatus can be used for items permitted for each individual, and desired data can be selected on the operation panel. Then, the selected data can be printed.

JP 2002-240398 A

However, the above-described conventional technology has a problem that the capacity of the HDD is compressed.
This is because, after personal authentication, unless the desired data is selected on the operation panel, this data cannot be printed, and the user does not recognize this unselected data as an object to be erased from the HDD.

As described above, in this technology, no special consideration is given to the point of positively erasing user data from the HDD.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image forming apparatus and a program that can solve the above-described problems and reliably ensure the capacity of the HDD.

  A first invention for achieving the above object is based on a storage unit for storing a job related to a user, an information acquisition unit for reading information on an IC card possessed by the user, and information read by the information acquisition unit. If the determination by the authentication determination unit and the authentication determination unit is right, the job related to this user is deleted from the storage unit without waiting for the user's operation. A processing execution unit.

According to the first invention, the image forming apparatus includes the storage unit, and the storage unit can store a job related to the user. On the other hand, this apparatus is also provided with an information acquisition unit, and personal authentication using an IC card is possible by reading information on the IC card possessed by the user.
Specifically, the authentication determination unit determines whether or not the user who has the IC card can use the image forming apparatus.

If it is determined that the user can use the device, the process execution unit deletes the job related to the user from the storage unit without requiring selection of desired data on the panel as in the past. ing.
As described above, since the job can be forcibly deleted at the timing of personal authentication, the capacity of the storage unit can be reliably ensured. As a result, it contributes to obtaining the optimum performance of the apparatus.

According to a second aspect, in the configuration of the first aspect, the processing execution unit prints a job related to the user and deletes the printed job from the storage unit.
According to the second invention, in addition to the operation of the first invention, the process execution unit forcibly prints the job at the timing of personal authentication. Thereby, it is possible to alert the user who viewed the printed matter that the job related to the user is pressing the capacity of the storage unit, and that the capacity of the storage unit is finite.
In addition, after the personal authentication, the operation of selecting the desired data on the panel is not required, so that the convenience for the user is improved as compared with the conventional case.

According to a third aspect of the present invention, in the configuration of the first or second aspect, when the determination of the authentication determination unit is right, the retention period of the job related to the user is determined without waiting for the user's operation. Only when the job threshold value is exceeded, it further includes an area release determination unit that determines to delete the exceeding job from the storage unit.
According to the third invention, in addition to the operation of the first and second inventions, an area release determination unit is further provided, and the determination unit has a job retention period exceeding a predetermined job threshold. Only when the job is to be deleted forcibly at the timing of personal authentication. In other words, when the retention period does not exceed the job threshold, the process does not shift to job deletion, so that an opportunity to perform only personal authentication can be secured.

According to a fourth invention, in the configuration of the third invention, the job threshold is a period during which an unnecessary job can be assumed to be left in the storage unit.
According to the fourth invention, in addition to the operation of the third invention, if the job to be erased is determined based on a period during which it is possible to simulate that an unnecessary job is left in the storage unit, It is possible to prevent the deletion of a highly important job while ensuring the capacity of the copy.

A fifth invention is a program for an image forming apparatus capable of personal authentication using an IC card.
The program is provided in the computer of the apparatus. In the computer, a procedure for saving a job related to the user in the storage unit, a procedure for reading the information of the IC card possessed by the user, and the read information Based on the procedure for determining whether or not to use the device based on the user and when it is determined that the user can use the device, the retention period of the job related to the user is determined without waiting for the user's operation. Procedure for determining whether or not the job threshold is exceeded, a procedure for printing a job that exceeds the job threshold only when the job retention period exceeds the job threshold, and a procedure for deleting the printed job from the storage unit And execute.

According to the fifth aspect of the present invention, a job to be forcibly processed is determined at a timing when it is determined that the user can use the apparatus by personal authentication using an IC card. In other words, if the retention period does not exceed the job threshold, the process does not shift to job processing, so that an opportunity to perform only personal authentication can be secured.
In addition, since this job is forcibly printed at the time of personal authentication, let the user who viewed this printed material know that the job related to the user was pressing the capacity of the storage unit, It can be noted that the capacity of the storage unit is finite.

In addition, after the personal authentication, the operation of selecting the desired data on the panel is not required, so that the convenience for the user is improved as compared with the conventional case.
Further, since the job is forcibly deleted, the capacity of the storage unit can be surely ensured, which contributes to obtaining the optimum performance of the image forming apparatus having this program.

  According to the present invention, since the act of performing personal authentication is a job erasing operation, it is possible to provide an image forming apparatus and a program that reliably secure the capacity of the storage unit.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a system according to the present embodiment. The system can use an image forming apparatus by a plurality of users (users) such as a company office, and is configured using a network 2 such as a LAN. Is done. An image forming apparatus 4, a server 6, and a client PC 8 are connected to the network 2.

  FIG. 2 shows a digital multifunction peripheral, which is an example of the image forming apparatus 4, a so-called multifunction peripheral (hereinafter referred to as MFP) from the upper right front. In the figure, the front surface of the MFP 4 facing the user and the right side surface of the MFP 4 can be seen. The MFP 4 includes an in-body discharge type apparatus main body 10, and a discharge tray 15 is formed inside the main body 10.

  An automatic document feeder (Auto Document Feeder, hereinafter referred to as ADF) 17 is mounted on the upper side of the paper discharge tray 15. When the MFP 4 is used as a copying machine, a facsimile machine, or a network scanner, a document is transported from the ADF 17. The image surface is optically read by the optical scanner unit 22.

  An operation panel 28 is installed on the front side of the scanner unit 22. A plurality of operation keys and switches for various user operations are arranged on the panel 28, and an operation screen 29 for displaying various information such as character information and guidance images is displayed at the center of the panel 28. Is provided. The contents of these operations are notified to the controller 50 in FIG.

  On the other hand, as shown in FIG. 2, a front loading type paper supply device is disposed below the apparatus main body 10. This supply device is provided with two upper and lower sheet feed cassettes 11 along the height direction of the main body 10, and each cassette 11 is configured to be detachable from the main body 10. An openable manual feed tray 13 is also provided on the right side surface of the main body 10.

FIG. 3 is a schematic configuration diagram of the MFP 4. The MFP 4 is connected to the network 2 via a network interface (IF) 26 and further connected to a public line. The MFP 4 executes various operations in accordance with program instructions.
The MFP 4 has, for example, a print function (Copy function), a transmission function (Send function), and a storage function (Box function).

Specifically, the HDD (storage unit) 32 includes a box area 34, and includes various jobs such as a print job transmitted from the client PC 8, a scan job read by the scanner unit 22, and a facsimile job received by the FAX communication unit 24. Are sequentially stored and have a Box function.
Further, the MFP 4 includes a memory 30. The memory 30 includes a ROM, a RAM, and the like. In this embodiment, a processing operation program based on personal authentication using an IC card is stored.

The above-described FAX communication unit 24 also has a Send function, and transmits a facsimile job stored in the HDD 32 to the other party.
The print engine 20 is connected to the ADF 17 that transports the document to the image reading position of the scanner unit 22, the paper feed cassette 11 that stores the paper, the manual feed tray 13, and the image forming unit that transfers the image to the paper, and is stored in the HDD 32. The printed job is output to the paper discharge tray 15 and has a Copy function.

The print engine 20 can also be connected to a post-processing device that performs sorting, punching, stapling, and the like on the transferred paper.
Here, a card reader (information acquisition unit) 40 is installed in the MFP 4 of this embodiment. Specifically, as shown in FIG. 2, the reader 40 is formed in a box shape, for example, and is disposed on the right side surface of the apparatus main body 10 having the manual feed tray 13, and faces the IC card held by the user. It has an antenna and a lamp that can display the authentication result.

The IC card possessed by the user is, for example, a passive type that does not have a power source, and an IC chip is embedded therein. The IC chip has a function of rewriting and appending data to the memory, and further has a function of communicating with the antenna of the card reader 40.
Specifically, the user operates the client PC 8 to create a print job, inputs a password, and transmits the print job from the PC 8 to the MFP 4 via the network 2.

Thereafter, this user leaves the PC 8 and stands in front of the MFP 4 in order to receive the previously created print job. Then, in order to prevent information leakage due to misplacement of printed matter using, for example, a private printing function, the held IC card is held over the card reader 40. The password may be input on the panel 28.
The antenna of the card reader 40 transmits radio waves, and when the IC card receives the radio waves, it generates necessary power therein, and a request signal from the card reader 40 is supplied to the IC chip to perform signal modulation or Demodulation, logical operation, memory access, etc. are executed.

On the other hand, the answer signal from the IC chip is received by the antenna and supplied to the card reader 40. Thereby, non-contact wireless communication is possible between these IC cards and the card reader 40, and the card reader 40 can read information such as the IC card number of the IC card.
The card reader 40 is connected to the controller 50 (FIG. 3), and information on the IC card is output to the controller 50.

  The controller 50 also controls various operations of the MFP 4. The controller 50 is an element that functions as a computer and has hardware resources such as a CPU. The controller 50 uses the hardware resources to execute a predetermined program, and operates the print engine 20, the scanner unit 22, and the FAX communication unit 24 described above. In this example, private printing is executed by operating the engine 20.

Incidentally, the controller 50 according to the present embodiment includes an authentication determination unit 52, an area release determination unit 54, and a process execution unit 56.
Upon receiving the reading result from the card reader 40, the authentication determination unit 52 compares the received information with, for example, an IC card number stored in the server 6 and user restriction information, and the user who possesses this IC card. Whether to use the MFP 4 is determined.

The authentication determination unit 52 can also acquire the user ID, log, and the like of the user from the server 6, and the above-described determination results and acquisition results are output to the area release determination unit 54.
When the user can use the MFP 4, the area release determination unit 54 determines job processing related to the user without waiting for the user's operation on the operation screen 29.

Specifically, the area release determination unit 54 determines to print a print job stored in the HDD 32 or to delete the printed job from the HDD 32 in this embodiment. The determination result is output toward the process execution unit 56.
The process execution unit 56 outputs to the print engine 20 that the print job determined by the area release determination unit 54 is to be printed. Subsequently, when the processing execution unit 56 receives a print completion signal from the engine 20, the job is deleted from the HDD 32.

More specifically, FIG. 4 shows processing that the program causes the controller 50 to execute. Hereinafter, the operation of the MFP 4 configured as described above according to the present invention will be described.
When a user who has sent a print job from the PC 8 to the MFP 4 to use the private print function holds the IC card over the card reader 40 in order to receive the previously created print job, the authentication determination unit 52 authenticates the IC card. Start.

  Then, in step S401 in the figure, the authentication determination unit 52 determines whether the user who possesses the IC card should use the MFP 4, and when the MFP 4 can be used, that is, when it is determined YES, the process proceeds to step S402. If it is determined in step S401 that the MFP 4 cannot be used, the authentication wait state is entered.

  In step S402, the area release determination unit 54 immediately determines whether there is a print job transmitted by the user without waiting for the user to operate the operation screen 29. When there is a print job for the user stored in the HDD 32, that is, when it is determined YES, the process proceeds to step S403, and the area release determination unit 54 determines that the storage period of the print job is greater than a predetermined job threshold T. It is also determined whether or not it is too long.

Specifically, the job threshold T in this embodiment is a period (for example, one week to one month) in which it can be assumed that an unnecessary print job is left in the HDD 32, and this threshold T is stored in the memory 30. Yes.
Then, the area release determination unit 54 determines that the print job storage period exceeds the threshold T, that is, YES, as in the case where the print job storage period of the user is 40 days. If so, a print job exceeding the threshold value T is specified, the process execution unit 56 is instructed, and the process proceeds to step S404.

If there are a plurality of print jobs that have exceeded the threshold T, all print jobs that have exceeded the threshold T are specified.
In step S404, the process execution unit 56 instructs the print engine 20 to forcibly print the corresponding print job in the area release determination unit 54 in addition to the previously created print job. The engine 20 outputs signals to the paper feed cassette 11 and the image forming unit described above, and outputs these print jobs to the paper discharge tray 15. In this way, forced printing is executed following private printing.

Thereafter, the process execution unit 56 deletes the corresponding print job from the HDD 32 by the area release determination unit 54 and exits a series of routines.
On the other hand, when the user's print job stored in the HDD 32 does not exist in step S402 described above, or if the storage period of the print job is 5 days in step S403, as shown in FIG. When the retention period of the user's print job does not exceed the threshold value T, only private printing is executed, and a series of routines are quickly exited. This is because it cannot be assumed that an unnecessary print job is left in the HDD 32. As a result, the normal authentication operation, that is, only whether the MFP 4 is used by the user possessing the IC card is determined by the authentication determination unit 52.

If it is desired to print a print job with a storage period of 5 days according to the above example, it can be selected on the operation screen 29 after this normal authentication operation.
By the way, in the above-described embodiment, when personal authentication is performed, the print job stored in the HDD 32 is switched between forcible printing / erasing of the print job and the normal authentication operation on the basis of the threshold T regarding the storage period. However, other threshold values may be considered.

Specifically, in the example shown in FIG. 5, as in the above example, when the user holds the IC card over the reader 40, the authentication determination unit 52 starts authenticating the IC card and possesses the IC card. Whether the user uses the MFP 4 is determined (step S501).
If the authentication determination unit 52 allows the user having the IC card to use the MFP 4, the area release determination unit 54 immediately determines whether there is a print job transmitted by the user (step S502). Further, when the user's print job exists in the HDD 32, it is determined whether or not the storage period of the print job is longer than a predetermined first threshold T (step S503).

  The first threshold value T according to the example of FIG. 5 is set as a period in which, for example, a range of one week to two weeks can be assumed to be neglected, and the area release determination unit 54 temporarily assumes that the print job storage period of the user is If it is 15 days, that is, if it is determined to be YES, a print job exceeding the first threshold T is specified, and the process proceeds to step S504.

In step S <b> 504, the area release determination unit 54 determines whether the number of print jobs stored by the user in the HDD 32 is greater than a predetermined second threshold value N.
Specifically, the second threshold value N in this example is based on the fact that the load on the HDD 32 increases as the number of stored print jobs increases.

In other words, the retention period of the user's print job according to this example is 15 days, and although the burden on the HDD 32 is small compared to the example up to FIG. 4 (the retention period has passed 40 days), This is because there is a high possibility that an unnecessary print job is left in the HDD 32.
The second threshold value N according to this example is set in a range of 10 to 20, for example, and stored in the memory 30.

  Then, the area release determination unit 54 determines that the number of stored print jobs exceeds the second threshold value N, that is, YES if the number of stored print jobs of the user is 25. When the determination is made, a print job exceeding the second threshold value N is specified, the process execution unit 56 is instructed, and the process proceeds to step S505.

  In addition to the print job that the user really wanted to receive (for private printing), the process execution unit 56 includes a print job that exceeds the period of the first threshold T and exceeds the number of the second threshold N (for forced printing). Instructs the print engine 20 to perform forced printing. Thereafter, the process execution unit 56 deletes the printed print job specified by the threshold values T and N from the HDD 32 and exits the series of routines.

  On the other hand, when the user's print job stored in the HDD 32 does not exist in step S502 described above, and if the storage period of the print job does not exceed the first threshold T in step S503 described above. Furthermore, when the number of stored print jobs does not exceed the second threshold value N, a series of routines are quickly exited and normal authentication operation is performed.

Note that the size of the print job may be considered in addition to the storage period and the number of storage. This is because the size also affects the capacity of the HDD 32.
As described above, according to this embodiment, the MFP 4 includes the HDD 32, and the HDD 32 can store a print job created by the user of the client PC 8. On the other hand, the MFP 4 is also provided with a card reader 40. By reading information on the IC card possessed by the user, personal authentication using the IC card is possible.

  Specifically, the authentication determination unit 52 determines whether or not the user who has the IC card can use the MFP 4. If it is determined that this user can use the MFP 4, the process execution unit 56 deletes the print job related to this user from the HDD 32 without requiring selection of desired data on the panel as in the prior art. Yes.

  In this way, the act of holding the IC card is a processing operation, and the print job can be forcibly deleted at the timing of personal authentication, so that the capacity of the HDD 32 can be ensured reliably. As a result, this contributes to obtaining the optimum performance of the MFP 4.

Further, the process execution unit 56 forcibly prints the job at the timing of personal authentication. As a result, the user who sees the printed matter on the paper discharge tray 15 can be notified that the print job related to the user is pressing the capacity of the HDD 32, and can alert the user that the capacity of the HDD 32 is finite. .
In addition, since it is not necessary to select desired data on the panel after performing personal authentication, the convenience of the user is improved as compared with the conventional case where selection is required for each data.

  Furthermore, an area release determination unit 54 is further provided. This determination unit 54 is for forcibly deleting at the timing of personal authentication only when the storage period of the print job exceeds a predetermined job threshold T. Determine the print job. In other words, when the storage period does not exceed the threshold T, the process does not shift to erasing the print job, so that an opportunity to perform only personal authentication can be secured.

  This can be classified into two modes: when the user performs personal authentication using an IC card, the MFP 4 receives the previously created print job, or operates the operation screen 29 to transmit a facsimile, for example. In view of the latter aspect, there is a case where the user may only expect to perform a normal authentication operation.

Furthermore, if a print job to be erased is determined based on a period in which it can be assumed that an unnecessary print job is left in the HDD 32, the capacity of the HDD 32 is surely secured by using personal authentication by IC card as a trigger. However, it is possible to prevent erasing of a print job with high importance.
The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims.

For example, in each of the above embodiments, the job is forcibly printed and then deleted. However, the fact that the forcible printing has been executed, the fact that the print job has been deleted, and the details thereof are displayed on the panel 28 and displayed to the user. You may let me know. Further, in view of securing the capacity of the HDD 32, only erasing from the HDD 32 may be executed without printing this job. This also saves paper.
In addition to the print job created by the user, the job of the present invention may be a scanner unit 22 read by the user or a facsimile job addressed to the user. This is because the capacity of the HDD 32 can be pressed in any case.

Finally, the above-described MFP 4 is an example of an image forming apparatus, and the present invention can naturally be applied to a copying machine, a printer, a facsimile, or the like that can perform personal authentication using an IC card.
In any of these cases, similarly to the above, there is an effect that the capacity of the storage unit can be reliably ensured.
