The controller 104 includes a CPU 105, a memory 106, an interface 107, and an HDD 109. The controller 104 is connected to a computer terminal 117 that is an external device via an interface 107 such as a LAN, and receives a print job from the computer terminal 117. The print job includes print setting information set on the computer terminal 117 and print data created using an application program on the computer terminal 117. In addition, when receiving a print job, the controller 104 also receives information indicating an IP address as information for identifying the computer terminal 117.
The CPU 105 controls the entire image forming apparatus 101 based on a program stored in the memory 106. The memory 106 includes a DRAM that functions as a work area for the CPU 105, and a memory 106 that includes a ROM that stores a program read by the CPU 105.
The operation unit 108 accepts an operator (user) instruction for the image forming apparatus 101. The operation unit 108 also functions as an operation screen and a display unit that displays the state of the apparatus.

The HDD 109 stores a print job received from the external computer terminal 117 via the interface 107. The HDD 109 stores various data such as image data read by the scanner unit 102 and setting information of the image forming apparatus 101 received via the operation unit 108.
The personal identification authentication unit 110 includes a camera 111 and a face authentication unit 112 which are examples of an imaging unit. The face authentication unit 112 includes a face authentication control unit 113, a motion capture unit 114, and a face authentication data storage unit 115.

The face authentication control unit 113 captures the face of the operator with the camera 111, generates face data indicating the captured face, and realizes a face authentication function based on the face data. Here, a known technique can be used as the face recognition means and the face authentication means.
The motion capture unit 114 stores a control program for realizing a motion capture function for performing motion capture on data indicated by an image captured by the camera 111. The face authentication data storage unit 115 stores motion data (user face information) indicating a preset motion.

The predetermined motion is, for example, an operation in which a person approaches the camera 111 direction. Note that the action of a person approaching the image forming apparatus 101 indicates that the line of sight faces the direction of the camera 111.
Further, the motion data stored in the face authentication data storage unit 115 may be configured to store a plurality of types of motion data instead of one type. Furthermore, face data of an operator who uses the apparatus is registered in the face authentication data storage unit 115 in advance.
As shown in FIG. 2, the face data includes face data of each operator, operator ID, operator name data indicating an operator name, PC name and IP address of each computer terminal 117, and will be described later. A take-out flag and the like are stored in association with each other.

The camera 111 is a video camera, for example, and photographs the periphery (predetermined range) of the image forming apparatus 101. In addition, the camera 111 detects a user present in an image captured by the video camera. As a result, the image forming apparatus 101 detects a user existing in the vicinity (predetermined range) of the image forming apparatus 101. In addition, a well-known technique can be used for the technique which detects the user contained in the image which image | photographed the user.

I have. Here, the units are, for example, the scanner unit 102, the printer unit 103, the controller unit 104, the operation unit 108, and the personal authentication specifying unit 110.

  The table shown in FIG. 2 has been described as being stored in the face authentication data storage unit 115, but may be stored in the HDD 109.

Next, the power control operation of the image forming apparatus 101 shown in FIG. 1 will be described with reference to the flowchart of FIG. Each step shown in the flowchart of FIG. 3 is realized by the CPU 105 or the face authentication control unit 113 executing a program stored in the memory 106 or the memory included in the face authentication control unit 113.
In the present embodiment, printing is executed from the computer terminal “AA11” owned by the person named “ABC” specified by the operator name data in the table shown in FIG. This is a flow when the printed matter discharged to the paper discharge unit is picked up.

First, in step S <b> 101, when the CPU 105 receives a print job from the computer terminal 117 via the interface 107, the CPU 105 stores the print job in the HDD 109. Further, the CPU 105 analyzes the print job using the memory 106, develops it into image data, and stores this in the HDD 109. The CPU 105 also receives the IP address of the computer terminal 117 that transmitted the print job, and stores it in the HDD 109 in association with the image data of the print job stored in the HDD 109. Note that the CPU 107 may receive the IP address of the computer terminal 117 as information included in the print job instead of receiving it from the computer terminal 117 separately from the print job.
In step S102, the CPU 105 outputs the image data stored in the HDD 109 to the printer unit 103, and the printer unit 103 sequentially prints the received image data on recording paper. At the same time, the CPU 105 can determine the user who sent the print job by comparing the IP address acquired in S101 with the personal data in the table shown in FIG. For example, when the IP address is “xx.xx.xx.0”, the CPU 105 can easily determine that the user who transmitted the print job is “ABC”. When the CPU 105 determines that the user who transmitted the print job is the user “ABC”, the CPU 105 sets the take-out flag of the user “ABC” to ON (set to 1).

  Thereafter, in step S103, the CPU 105 causes the printer unit 103 to print the print data stored in the HDD 109. When printing is completed, the CPU 105 determines whether the image forming apparatus has received a new print job or the predetermined time has passed without accepting an operation by the user via the operation unit 108. 101 is shifted to a low power consumption state. In this embodiment, the low power consumption state refers to a state in which power is supplied to the personal identification authentication unit 110 and the controller 104, and power is supplied to the scanner unit 102, the printer unit 103, and the operation unit 108. No state.

However, the power may be supplied only to the personal identification authentication unit 110 and the face authentication unit 112 included in the personal identification authentication unit 110 may perform the processes of S104 to S109. Alternatively, a configuration may be employed in which a plurality of low power consumption states are provided, and the CPU 105 sequentially turns off the power supply of each unit after a certain time has elapsed.
That is, shifting from the normal power consumption state in which power is supplied to the scanner unit 102, the printer unit 103, the controller 104, the operation unit 108, and the personal identification authentication unit 110 to a low power consumption state is changed to a low power consumption state. It is said to migrate.
In step S <b> 104, the personal identification authentication unit 110 monitors whether there is a user approaching the periphery of the image forming apparatus 101. If the person is recognized by the camera 111, the face managed by the table shown in FIG. 2 stored in the face authentication data storage unit 115 and the face of the person recognized by the face authentication unit 112 in S105. Compare with the data. Then, the face authentication unit 112 identifies a user who approaches the periphery of the image forming apparatus 101 based on the comparison result. If the user cannot be identified, the image forming apparatus 101 is shifted to the normal power consumption state. Then, the process proceeds to S106. In step S <b> 106, the face authentication control unit 113 determines whether the identified user's take-out flag is in the ON state.

Here, if the CPU 105 determines that the carry-out flag of the identified user is OFF, the process proceeds to S107.
In step S <b> 107, the CPU 105 causes the power supply control unit 116 to start supplying power to each unit of the image forming apparatus 101, thereby returning from the low power consumption state to the normal power consumption state, and ends this processing. This is control when the user approaching the image forming apparatus 101 is not the user who transmitted the print job, and it is unlikely that he / she has picked up the printed matter discharged by the execution of the print job. Therefore, the image forming apparatus 101 is shifted from the low power consumption state to the normal power consumption state. As a result, even if the user does not give an instruction to shift the image forming apparatus 101 to the normal power consumption state, the image forming apparatus 101 quickly shifts to the normal power consumption state, and the convenience of the image forming apparatus 101 is improved. be able to.

On the other hand, if the CPU 105 determines in S106 that the identified user's take-out flag is ON, the process proceeds to S108.
In step S <b> 108, the CPU 105 maintains the low power consumption state of the image forming apparatus 101 without returning the image forming apparatus 101 from the low power consumption state. At this time, the CPU 105 turns off the carry-out flag of the identified user and ends this processing. This is a control that takes into account that a user approaching the image forming apparatus 101 is a user who has transmitted a print job, and that the user is likely to pick up the printed matter that has been ejected as a result of the execution of the print job. is there. In such a case, since the image forming apparatus 101 can be maintained in the low power consumption state, the power consumption can be reduced.

By controlling as described above, the image forming apparatus 101 can be shifted from the low power consumption state to the normal power consumption state in response to detecting a user approaching the image forming apparatus 101. Thereby, user convenience in the image forming apparatus 101 can be improved.
In addition, when there is a high possibility that the user who has approached the image forming apparatus 101 has just picked up the printed matter of the print job from the computer terminal 117, the low power consumption state of the image forming apparatus 101 can be maintained. . Thereby, power consumption in the image forming apparatus 101 can be suppressed.
When the CPU 105 determines that the result of the comparison in S105 does not match any face data stored in the face authentication data storage unit 115, the CPU 105 controls as follows.
In this case, the CPU 105 shifts the image forming apparatus 101 to the normal power consumption state. Thereby, convenience when an unregistered user uses the image forming apparatus 101 can be improved.
Alternatively, the CPU 105 may maintain the image forming apparatus 101 in the low power consumption state without shifting to the normal power consumption state, or whether the user maintains the low power consumption state via the operation unit 108. May be set in advance.

[Second Embodiment]
The second embodiment is different from the first embodiment in the personal identification authentication unit 110 in FIG. An example of the personal identification authenticating unit 110 in the second embodiment is shown in FIG. In this example, the computer terminal 117 designates secure printing as a print job.

FIG. 4 is a block diagram illustrating another configuration example of the personal identification authentication unit 110 shown in FIG. In the first embodiment, an individual is identified using the user's face photographed by the camera 111. In the second embodiment, an RFID (RFID tag) system capable of reading information without contact is used. Use. Note that the RFID system is an abbreviation for Radio Frequency Identification System.
The RFID system is an ID system using radio waves / electromagnetic waves as a medium, and includes an electromagnetic coupling method, an electromagnetic induction method, a microwave method, an optical method, and the like.
For example, in the electromagnetic induction method, communication is performed between the IC tag reader / writer 201 and the IC tag 206 mainly using an electromagnetic wave of 250 K or less or a long / medium wave band of 13.56 MHz band. The IC tag reader / writer 201 reads ID data stored in the IC tag 206 when the IC tag 206 exists in a range where wireless communication is possible. Further, the IC tag reader / writer 201 stores data in the IC tag 206 when the IC tag 206 exists in a range where wireless communication is possible. The ID card 205 is carried by a user who uses the image forming apparatus 101.

  The IC tag authentication unit 202 includes an IC tag authentication control unit 203 and an IC tag authentication data storage unit 204. The IC tag authentication control unit 203 performs personal authentication based on different ID data for each IC tag acquired by the IC tag reader / writer 201. The IC tag authentication data storage unit 204 stores personal data information as shown in FIG.

Further, the range in which information can be read / written to the ID card in a non-contact manner is set to a radius of about 1 m from the ID tag reader / writer 201.
Next, the power control operation of the image forming apparatus 101 shown in the second embodiment will be described with reference to the table shown in FIG. 5 and the flowchart shown in FIG. In FIG. 6, S201 to S213 indicate steps, which are realized by the CPU 105 or the IC tag authentication control unit 203 executing a program stored in the memory 106 or the memory included in the IC tag authentication control unit 203.
In addition, S201, S204, S205, and S206 are substantially the same as those in the first embodiment, and thus are omitted. As a difference, in S201, the CPU 105 can receive a secure print job with a password specified.

In step S202, the CPU 105 of the image forming apparatus 101 determines whether the received print job is a secure print job. If the CPU 105 determines that the print job is a secure print job, the process proceeds to step S203. In step S203, the CPU 105 does not print immediately, but compares the IP address of the computer terminal 117 with the table shown in FIG. 5 to identify the user who sent the print job. That is, this IP address is used as identification information for identifying the computer terminal 117 operated by the user and the user. Then, the CPU 105 turns on the secure print flag and the carry-out flag of the identified user, and proceeds to S206. The table shown in FIG. 5 has been described as being stored in the IC tag authentication data storage unit 204, but may be stored in the HDD 109.
Here, the secure print job refers to installing a printer driver in the computer terminal 117 that transmits a password input by the user in association with the print job when the print job is transmitted. The computer terminal 117 transmits the print job and password to the image forming apparatus 101 using the printer driver, whereby the print job and password are transmitted to the image forming apparatus 101.
The image forming apparatus 101 that has received the print job data and the password in this way does not immediately start the printing process, but temporarily stores the print job data and the password data in a storage device in the image forming apparatus 101, for example, Save in the HDD 109.

When the user wants the image forming apparatus 101 to perform printing according to the print job data, the following operation is performed.
First, using the operation unit 108 provided in the image forming apparatus 101, for example, a print job list related to a print job stored in the HDD 109 is displayed on the operation unit 108.
Then, the user selects a target print job from the job list displayed on the operation unit 108 and inputs a password. When the password is input, the CPU 105 of the image forming apparatus 101 determines whether or not the password input from the operation unit 108 by the user matches the password stored in the storage device together with the print job data. Only when it is determined that the passwords match, the CPU 105 executes this print job and starts the printing process. On the other hand, if the passwords do not match, the CPU 105 displays an error message on the operation unit 108 without executing the print job.

At this time, since the operator is already in front of the image forming apparatus 101, the target confidential document can be received without being seen by a third party and without being stolen by the third party. In this embodiment, ID data for identifying the user is used instead of the password. In addition, in order to execute a secure print job stored in the image forming apparatus 101, the user may input ID data via the operation unit 108. In addition, the following method is used. You can also. The user brings the ID card stored in the ID card 205 close to the IC card reader / writer 201 of the image forming apparatus 101. The CPU 105 of the image forming apparatus 101 reads ID data in the IC card 205 via the IC card reader / writer 201. Then, a secure print job corresponding to the same ID data as the read ID data is executed. Further, the CPU 105 does not execute secure print jobs corresponding to different ID data.
Returning to the flowchart of FIG. In S <b> 207, the CPU 105 compares the ID data of the ID card 205 read by the IC tag reader / writer 201 with the ID data shown in FIG. 5 stored in the IC tag authentication data storage unit 204. As a result of the comparison, the CPU 105 determines whether there is matching ID data in the ID data stored in the IC tag authentication data storage unit 204.

  If the CPU 105 determines that there is ID data that matches the ID data stored in the IC tag authentication data storage unit 204, the CPU 105 identifies the user according to the ID data, and proceeds to S208. In S208, the CPU 105 confirms whether or not the identified user's take-out flag is in the ON state. If the CPU 105 determines that the take-out flag is OFF, the process proceeds to S209. In step S209, the image forming apparatus 101 is returned from the low power consumption state to the normal power consumption state, and the process ends. This is control when the user carrying the ID card 205 is highly likely to operate the operation unit. Therefore, the image forming apparatus 101 is shifted from the low power consumption state to the normal power consumption state. As a result, even if the user does not give an instruction to shift the image forming apparatus 101 to the normal power consumption state, the image forming apparatus 101 quickly shifts to the normal power consumption state, and the convenience of the image forming apparatus 101 is improved. be able to.

On the other hand, if the CPU 105 determines in S210 that the take-out flag is ON, the process proceeds to S210.
In step S210, the CPU 105 confirms the state of the secure print flag of the identified user, and determines whether the identified user is a user who has executed secure printing. If the CPU 105 determines that the user is not executing secure printing, the process proceeds to S211.
In step S211, the CPU 105 does not return the image forming apparatus 101 from the low power consumption state to the normal power consumption state. In step S213, the CPU 105 turns off the take-out flag and ends this processing. This is a control when the user carrying the ID card 205 is less likely to operate the operation unit and is more likely to simply pick up the printed material discharged to the paper discharge unit of the image forming apparatus 101. is there. In such a case, since the image forming apparatus 101 can be maintained in the low power consumption state, the power consumption can be reduced.

On the other hand, if the CPU 105 determines in S210 that the user has executed secure printing, the process proceeds to S212. In step S212, the CPU 105 starts printing a secure print job. Specifically, the CPU 105 executes the secure print job when the ID data read from the ID card 205 matches the ID data of the secure print job. In this case, the CPU 105 may execute the secure print job by causing the power control unit 116 to supply power to the print unit 103 that is a unit necessary for executing the secure print job. At this time, since power is not supplied to the operation unit 108 and the scanner unit 102, it is possible to save power to a unit that is not necessary for executing the secure print job while executing the secure print job. The CPU 105 may control the power supply control unit 116 to cut off the power to the printing unit 103 when a predetermined time has elapsed after the execution of the secure print job. Thereafter, in S213, the CPU 105 turns off the take-out flag and ends the present process.
As described above, the present embodiment is different from the first embodiment in that an RFID system is used as the personal identification authentication unit and a secure print job process is added. However, the present invention is not limited to the first and second embodiments, and any combination of the configurations described in the first and second embodiments is included in the scope thereof. .
By controlling as described above, the image forming apparatus 101 can be shifted from the low power consumption state to the normal power consumption state in response to detecting a user approaching the image forming apparatus 101. Thereby, user convenience in the image forming apparatus 101 can be improved.
In addition, when there is a high possibility that the user who has approached the image forming apparatus 101 has just picked up the printed matter of the print job from the computer terminal 117, the low power consumption state of the image forming apparatus 101 can be maintained. . Thereby, power consumption in the image forming apparatus 101 can be suppressed.
In the above-described embodiment, the image forming apparatus 101 consumes less power when a predetermined time elapses in a state where it does not accept a print job or a state where a user operation is not accepted via the operation unit 108. An example of shifting to the power state has been described. This predetermined time can be set to 10 minutes, 5 minutes, or the like. The predetermined time may be a value set in advance in the image forming apparatus 101 or may be changed by the user operating the operation unit 108.
In the above-described embodiment, the image forming apparatus 101 (printing apparatus) has been described as a multifunction machine including the scanner unit 102 and the printer unit 103. However, the image forming apparatus 101 (printing apparatus) may be a printer including the printer unit 103 without the scanner unit 102. Good.
