Abstract
In an image processing apparatus, a power switcher starts supplying power in a second mode in which the power is supplied to a controller but not supplied to an image processor, when a state in which the power switcher receives no power is changed to a state in which the power switcher receives power. When a state in which no power is supplied to the controller is switched to a state in which power is supplied to the controller in the second mode and when the power switcher is receiving no power from a commercial power source, the controller, based on particular information, switches, before a first processing, a power supply mode from the second mode to a first mode in which no power is supplied or switches the power supply mode from the second mode to the first mode after the first processing.
Claims14
An image processing apparatus, comprising:
- an image processor configured to perform image processing;
- a storage;
- a power switcher comprising (i) a first connector connected to a commercial power source to receive electric power and (ii) a second connector connected to a power source of a bus-connected device to receive electric power;
- and
- a controller,
- wherein the power switcher is selectively in one of at least three power supply modes, each of which is a mode of supply of the electric power from at least one of the commercial power source and the bus-connected device,
- wherein the at least three power supply modes comprise:
- a first mode in which no electric power is supplied to any of the controller and the image processor;
- a second mode in which the electric power is supplied to the controller, and no electric power is supplied to the image processor;
- and
- a third mode in which the electric power is supplied to the controller and the image processor,
- wherein the power switcher is configured to start supplying the electric power in the second mode when a state of the power switcher is changed from a state in which the power switcher receives no electric power from any of the commercial power source and the power source of the bus-connected device, to a state in which the power switcher receives the electric power from at least one of the commercial power source and the power source of the bus-connected device, and
- wherein the controller is configured to:
- determine whether the power switcher is receiving the electric power from the commercial power source, when a state of the controller is switched from a state in which no electric power is supplied to the controller to a state in which the electric power is supplied to the controller in the second mode;
- and
- when the controller determines that the power switcher is receiving no electric power from the commercial power source, execute, based on particular information stored in the storage, one of (a) switching the power supply mode of the power switcher from the second mode to the first mode before execution of a first processing and (b) switching the power supply mode of the power switcher from the second mode to the first mode after execution of the first processing.

- wherein the controller is configured to:
- determine whether the power switcher is receiving the electric power from the commercial power source, when a state of the controller is switched from a state in which no electric power is supplied to the controller to a state in which the electric power is supplied to the controller;
- determine, based on particular information stored in the storage, whether the power supply mode of the power switcher is to be changed to the first mode before execution of a first processing or after execution of the first processing;
- switch the power supply mode of the power switcher from the second mode to the first mode before execution of the first processing, when the controller determines that the power switcher is receiving no electric power from the commercial power source and when the controller determines that the power supply mode of the power switcher is to be changed to the first mode before execution of the first processing;
- and
- switch the power supply mode of the power switcher from the second mode to the first mode after execution of the first processing, when the controller determines that the power switcher is receiving no electric power from the commercial power source and when the controller determines that the power supply mode of the power switcher is to be changed to the first mode after execution of the first processing.
