The storage unit 210 stores programs executed by the CPU 202 (such as OS and application programs). The storage unit 210 stores job data and image data. The job data refers to data for the image forming apparatus 101 to execute a function, such as PDL data for print processing received from a client PC (not shown) via the LAN I / F 208, for example.
A reader I / F 206 is an I / F for communicating with the document reading unit 104 to exchange commands / statuses and image data. A printer I / F 211 is an I / F that communicates with the printer unit 109 to exchange commands / status and image data.

  A FAX I / F 209 is an I / F that is connected to a public telephone line and performs FAX image communication. A LAN I / F 208 is connected to a network such as Ethernet (registered trademark), and exchanges job data and commands / statuses.

  The card reader I / F 204 is an I / F that communicates with the card reader unit 107, and detects the card read by the card reader unit 107, receives card data, and transmits data to be written to the card. The detection unit I / F 203 is an I / F that communicates with the detection unit 105, detects a power source activation factor (factor that causes the power source to return to the first power mode), and receives the detected information. An operation unit I / F 207 is an I / F that communicates with the operation unit 106 and transmits data to be displayed on the display unit of the operation unit 106 and receives input information from a user such as a button or a touch panel. Note that the factor that causes the image forming apparatus to return from the energy saving mode to the normal mode according to the detection of the setting of the output paper by performing the operation of placing the sheet on the manual paper tray is also included in the factor that returns.

The power control unit 201 is a block that controls the transition between the normal mode and the energy saving mode of the image forming apparatus 101. Specifically, when the power mode is the first power mode, power is supplied to all of the plurality of units. In addition, when the power mode is the second power mode in which the power mode is lower than the first power mode, the power supply state from the power supply unit 102 is set so that power is supplied to some of the plurality of units.

  In FIG. 6, when a copy document is placed on the document tray, the detection sensor 601 transmits the detection signal to the receiving unit 602 by detecting the copy document. When receiving the detection signal, the receiving unit 602 notifies the control unit 603. When the control unit 603 of the detection unit 105 receives the detection signal from the reception unit 602, the control unit 603 holds the reception information of the detection signal in the memory 604. Then, the reception information of the detection signal is transmitted to the CPU 202 of the control unit 103. Thereafter, the CPU controls the power supply based on the detection information. Note that the memory 604 may hold one or more factors to be restored when detecting one or more different factors that cause the detection sensor 601 to return to the first power mode after shifting to the second power mode. Is possible.

<Energy saving mode control method>
FIG. 5 is a flowchart for explaining the power control method of the information processing apparatus according to the present embodiment. Hereinafter, an example of processing for returning from the energy saving mode in the image forming apparatus 101 that is an information processing apparatus will be described. Each step is performed by the CPU 202 included in the control unit 103 of the image forming apparatus 101 executing a control program. Realized.

Note that this flowchart starts executing when the image forming apparatus 101 is operating in the normal mode.
The image forming apparatus 101 determines whether or not there is a factor for shifting to the energy saving mode. If there is a factor for shifting to the energy saving mode, the process proceeds to S <b> 501 and transmits a notification of shifting to the energy saving mode to the operation unit 106. To do.
Then, the CPU 202 of the control unit 103 issues an energy saving mode transition command to the power supply control unit 201. Based on the power saving mode transition command to the power supply control unit 201, the power supply control unit 201 transmits a power supply control signal to the power supply unit 102 via the power supply control line. The power supply unit 102 stops power supply to some units of the image forming apparatus 101 based on the power supply control signal received from the power supply control unit 201. As a result, the image forming apparatus 101 shifts to the energy saving mode.

In the energy saving mode of the present embodiment, the power supply unit 102 supplies power to the operation unit 106, the card reader unit 107, and the detection unit 105 of the image forming apparatus 101. At that time, power is supplied to a part of the power return button or the like of the operation unit 106, and the screen of the operation unit 106 is in a state where nothing is displayed.
In the control unit 103, power is supplied to a part of the operation unit I / F 207, a part of the LAN I / F 208, and a part of the FAX I / F 209, but the power supply is stopped for the other parts.
Further, in the energy saving mode of the present embodiment, power supply from the power supply unit 102 to the document reading unit 104, the paper discharge unit 108, the printer unit 109, and the paper feed unit 110 is stopped. The energy saving mode only needs to be in a state where the power consumption is less than that in the normal mode. Which unit is supplied with power and which unit is stopped from supplying power is different from the present embodiment. It may be a thing.

<Power control with card authentication>
In the following, with reference to the flowchart of FIG. 5, regarding the power control example with card authentication control from the energy saving mode, the factor for returning from the power saving state to the normal power state is due to something other than card authentication and due to card authentication. Are described separately.
In step S501, the image forming apparatus 101 shifts to the energy saving mode as described above. In step S <b> 502, it is determined whether the image forming apparatus 101 includes the card reader unit 107. This determination is equivalent to determining whether the card authentication function is valid. If it is determined that the card reader unit 107 is valid, the process proceeds to S503. If it is determined to be invalid, the process proceeds to S509.

  In step S503, the image forming apparatus 101 continues the energy saving mode. Then, it is determined whether or not there is a return factor from the energy saving mode. For example, the user desires a copy operation and places a document on a document feeder. In this case, the detection sensor 601 of the detection unit 105 of the document feeder detects a document, determines that there is a document, and generates a document detection signal. The receiving unit 602 receives this signal, determines that there is a power source recovery factor, and transmits the detection signal to the control unit 603. At this time, it is determined that there is a cause for the power supply recovery even when the user brings the card close to the card reader unit 107. Whether or not there is a return factor is determined when the user places the document on the document feeder and then closes the card to the card reader unit 107 (case 1), and the user does not perform an operation such as placing the document on the document feeder. There is a case where a card is brought close to the card reader unit 107 (case 2).

(Case 1 power control)
In step S504, the control unit 603 of the detection unit 105 determines whether the return factor is due to card authentication. If it is determined that the return factor is other than card authentication, the process proceeds to S505. If it is determined that the return factor is due to card authentication, the process proceeds to S507 in order to return the power saving state to the normal power state ( Case 2).

On the other hand, if it is determined in S504 that the return factor is other than card authentication (Case 1), the process proceeds to S505, and the control unit 603 detects the detection sensor 601 of the detection unit 105 that is a return factor of the image forming apparatus 101. Is stored in the memory 604 and transmitted to the CPU 202 of the control unit 103.
Then, the image forming apparatus 101 maintains the energy saving mode, and in S506, the CPU 202 of the control unit 103 displays a card authentication screen (FIG. 7) generated on the operation unit 106 by display control via the operation unit I / F 207. To do. At this time, the image forming apparatus 101 enters a card authentication waiting state. The image forming apparatus 101 is maintained in the energy saving mode until the user authentication is successful. As a result of the card authentication of the user, the power supply is limited until the user authentication is not successful, so that useless power consumption can be reduced.

In step S <b> 507, the user brings the card 301 close to the card reader unit 107 of the image forming apparatus 101. Then, the receiving unit 305 of the card reader unit 107 reads information on a predetermined card 301 for authenticating the user, and the control unit 103 of the image forming apparatus 101 stores the read card information in the storage unit 210. Compare with card authentication data (user identification information). Here, if the comparison results match, the control unit 103 determines that the authentication is successful, and proceeds to S508.
In step S504, the CPU 202 of the control unit 103 of the image forming apparatus 101 reads the power recovery factor stored in the memory 604 of the detection unit 105. In step S508, the CPU 202 starts the image forming apparatus 101. At that time, the CPU 202 of the control unit 103 displays a function selection screen on the operation unit 106 (FIG. 8). Note that the activation of the image forming apparatus 101 in step S508 is to supply power to each unit so that the image forming apparatus 101 can start a predetermined job, and shift to a standby state in which image formation is possible.
According to Case 1, when the image forming apparatus 101 is in the energy saving mode and a return factor other than card reading occurs, the image forming apparatus 101 is changed from the sleep state to the standby state until the authentication succeeds with priority given to the card authentication. The power saving state can be maintained without shifting.

(Case 2 power control)
Hereinafter, when the image forming apparatus 101 is in the energy saving mode and the case of reading the card occurs without the case 1 (case 2), specifically, the user performs an operation such as placing a document or the like. This is a case where the card is brought close to the card reader unit 107 without performing the process. Hereinafter, the power control method of Case 2 will be described.
In S501 and S502, the image forming apparatus 101 has shifted to the energy saving mode. In the next S503, the detection unit 105 determines whether there is a factor for returning from the energy saving mode. Here, since the user does not perform an operation such as placing a document on the document table, the detection unit 105 determines that there is no return factor based on the operation, and for operating the image forming apparatus 101. This is a case where the user performs an operation of bringing the card close to the card reader unit 107 in order to log in (case 2).
In this case, since the user brings the card 301 close to the card reader unit 107 of the image forming apparatus 101, the determination in S504 is YES, and the process proceeds to S507. In step S <b> 507, the receiving unit 305 of the card reader unit 107 reads the card information, and the control unit 103 of the image forming apparatus 101 recognizes the card.

Specifically, the control unit 103 of the image forming apparatus 101 compares the read card information with the card authentication data stored in the storage unit 201. If the comparison results match, the control unit 103 determines that authentication is successful, and the process advances to step S508.
In step S <b> 507, the CPU 202 of the control unit 103 of the image forming apparatus 101 is activated to start supplying power to each unit of the image forming apparatus 101. The CPU 202 of the control unit 103 supplies power to the operation unit 106 and displays a function selection screen for accepting job processing until the image forming apparatus 101 is in a standby state, so that other units can operate normally. Wait until it becomes (standby state).
Thereafter, the process proceeds to S511, where it is determined whether the image forming apparatus 101 is in a standby state.
As described above, in the case 2, when the image forming apparatus 101 is in the energy saving mode state and there is no other return factor other than the card authentication, the image forming apparatus 101 is switched from the sleep mode to the normal mode (standby state) by the card authentication. It is an example of a process which performs electric power return.

(Case 3 power control)
Hereinafter, the operation will be described for the case where the card authentication is not performed (case 3).
In step S <b> 502, it is determined whether the image forming apparatus 101 includes the card reader unit 107. When the power switch of the image forming apparatus 101 is turned on and the image forming apparatus 101 is turned on, the CPU 202 of the control unit 103 confirms the state of each connected I / F. In order to confirm whether or not the card reader unit 107 is connected to the image forming apparatus 101, the CPU 202 of the control unit 103 confirms the detection state of the card reader with the control unit 603 of the detection unit 105. When it is determined that the card reader unit 107 is not installed, the state of the card reader port in the control unit 603 of the detection unit 105 is L level.
Therefore, the CPU 202 of the control unit 103 recognizes the state of the detection port of the card reader unit 107 as L level and determines that the card reader unit 107 is not provided. At this time, the process proceeds from S502 to S509.

Then, in the image forming apparatus 101, the control unit 103 determines whether there is a return factor as described above. If the control unit 103 determines that there is a return factor such as placing the document on the document table based on the output of the detection sensor 601, the process proceeds to S <b> 510 and the image forming apparatus 101 can be activated. .
As described above, even when the card authentication is not performed, control is performed to shift the image forming apparatus 101 to a standby state in which an image can be formed according to the power recovery factor.
According to the present embodiment, even if a factor for returning the power supply mode from the energy saving mode to the normal mode has already occurred, the power mode can be controlled not to return to the normal mode until the user authentication is successful.

In the above embodiment, the case where a predetermined card is used as the means for authenticating the user has been described. However, the authentication information recording medium is not limited to a card medium, and the present invention can also be applied to a case where the authentication information recording medium is configured by communication means carried by the user, for example, a smartphone or a pad device. The authentication information includes a user's face image, biometric information such as the retina and veins, and the like.
Further, the present invention can be applied even when a configuration is provided in which user authentication is started by detecting body temperature (heat source) when a human body approaches the main body.

  The present invention supplies a program that realizes one or more functions of the above-described embodiments to a system or apparatus via a network or a storage medium, and one or more processors in a computer of the system or apparatus read and execute the program This process can be realized. It can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
