JP7066668B2 - Image forming device and its control method, and program - Google Patents

Description

The present invention relates to an image forming apparatus , a control method thereof, and a program , and more particularly to a power-saving state recovery control technique in an image forming apparatus capable of short-range wireless communication with a short-range wirelessly mounted device.

Some conventional image forming devices shift to a state in which power consumption is reduced (so-called power saving state) when there is no operation request for a certain period of time or longer. As a method for realizing this, there is a control for stopping the clock supply of a functional module such as a printing unit that operates during normal operation but does not operate during power saving.

In addition, some image forming devices are configured to perform user authentication by bringing an RFID-tagged authentication card close to an image forming device including an RFID tag reader / writer.

On the other hand, short-range wireless communication between RFID tags and RFID tag readers / writers has appeared using the Near Field Communication (NFC) standard. The NFC communication protocol (protocol) enables not only the combination of RFID tags and RFID tag readers / writers, but also communication between readers / writers and transition to higher-speed alternative route communication (referred to as handover). By using this NFC, for example, not only the short-range wireless communication of the authentication data between the authentication card and the image forming apparatus but also the usage start information of the image forming apparatus is displayed, and the user can check the usage status of the image forming apparatus. A technique that makes it possible to grasp is disclosed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2010-136016

However, since the RFID tag reader / writer consumes a large amount of power, the power of the RFID tag reader / writer is turned off when the image forming apparatus is in the power saving state. Therefore, even if the RFID-tagged authentication card is brought close to the image forming apparatus, the image forming apparatus does not recover from the power saving state.

In addition, when the image forming device is in the power saving state, two actions of holding the authentication card with the RFID tag after returning from the power saving state by pressing the button on the device panel are required, which is not convenient for the user. There are challenges.

Further, in the image processing device described in Patent Document 1, the recovery time from the power saving state is not taken into consideration. For example, in order to use the handover during the authentication data communication in NFC, the image forming device is in the power saving state. Must not be.

Therefore, an object of the present invention is to provide an image forming apparatus , a control method thereof, and a program capable of recovering from the power saving state and starting communication with one action even in the power saving state.

In order to achieve the above object, the image forming apparatus of the present invention causes the controller to save power according to the detection of a controller capable of taking a power saving state and a mobile device using short-range wireless communication in the image forming apparatus. After returning from the state, the recovery means obtains authentication information from the mobile device via the short-range wireless communication, holds the acquired authentication information while the controller is in the power saving state, and after the controller returns. The controller has a means for transmitting the acquired authentication information to the controller, and the controller performs an authentication process for authenticating the user of the mobile device in the image forming apparatus according to the return from the power saving state. It is characterized by executing based on the authentication information and establishing wireless LAN communication with the mobile device.

According to the present invention , even in the power saving state, it is possible to recover from the power saving state and start communication with one action.
