Abstract

A digital multifunction peripheral including a contactless power feeding unit having a function of communicating with a terminal apparatus and a function of feeding the power in a contactless manner to the terminal apparatus is configured to detect a status of the digital multifunction peripheral, detect the presence or absence of a power receiving apparatus capable of communicating with the contactless power feeding unit, and, when such a power receiving apparatus is present, detect the status of the power receiving apparatus, and perform power-saving control based on the result of the detections.

Claims

1. A printing apparatus comprising:

a contactless power feeding unit configured to feed power wirelessly to a power receiving apparatus; and

a control unit configured to determine whether it is necessary to stop power feeding to the contactless power feeding unit based on a power-saving setting of the printing apparatus, in a case where the printing apparatus shifts to a power-saving mode,

wherein the control unit stops power feeding to the contactless power feeding unit, in a case where it is determined that it is necessary to stop power feeding to the contactless power feeding unit, and

wherein power feeding to the contactless power feeding unit is continued in the power-saving mode, in a case where it is determined that it is not necessary to stop power feeding to the contactless power feeding unit.

2. The printing apparatus according to claim 1, wherein the printing apparatus is a digital multifunction peripheral including the contactless power feeding unit, an image input device, and an image output device.

3. A method for controlling a printing apparatus, the method comprising:

feeding power wirelessly to a power receiving apparatus by a contactless power feeding unit;

determining whether it is necessary to stop power feeding to the contactless power feeding unit based on a power-saving setting of the printing apparatus, in a case where the printing apparatus shifts to a power-saving mode; and

stopping power feeding to the contactless power feeding unit, in a case where it is determined that it is necessary to stop power feeding to the contactless power feeding unit, and

wherein power feeding to the contactless power feeding unit is continued in the power-saving mode, in a case where it is determined that it is not necessary to stop power feeding to the contactless power feeding unit.

4. A printing apparatus comprising:

a printer configured to form an image on paper;

a contactless power feeding unit configured to feed power wirelessly to a power receiving apparatus; and

a control unit configured to determine whether it is necessary to stop power feeding to the contactless power feeding unit based on a power-saving setting of the printing apparatus, in a case where the printing apparatus shifts to a power-saving mode in which power feeding at least to the printer is stopped,

wherein the control unit stops power feeding to the contactless power feeding unit, in a case where it is determined that it is necessary to stop power feeding to the contactless power feeding unit, and

wherein power feeding to the contact power feeding unit is continued in the power-saving mode, in a case where it is determined that it is not necessary to stop power feeding to the contactless power feeding unit.

5. A method for controlling a printing apparatus, the method comprising:

forming an image on paper;

feeding power wirelessly to a power receiving apparatus by a contactless power feeding unit;

determining whether it is necessary to stop power feeding to the contactless power feeding unit based on a power-saving setting of the printing apparatus, in a case where the printing apparatus shifts to a power-saving mode in which power feeding at least to the printer is stopped; and

stopping power feeding to the contactless power feeding unit, in a case where it is determined that it is necessary to stop power feeding to the contactless power feeding unit, and

wherein power feeding to the contact power feeding unit is continued in the power-saving mode, in a case where it is determined that it is not necessary to stop power feeding to the contactless power feeding unit.
