Abstract

A power supply control apparatus that includes an instruction component, an execution component and a power supply control component is provided. The power supply control component is equipped with at least two measurement functions that have different measurement durations for cases in which the duration until interrupting the power supply to device(s) is measured, wherein measurement is activated with a first measurement function of relatively long measurement duration at a completion time of prior image processing, and measurement is activated with a second measurement function of relatively short measurement duration for device(s) to which power is being supplied at the time of completion of the prior image processing but which are not required in later image processing.

Claims

1. A power supply control apparatus comprising:

an instruction component for instructing image processing that selectively operates a plurality of devices;

an execution component that operates selected device(s) according to the image processing instructed with the instruction component and executes image processing; and

a power supply control component that controls so as to independently supply power or interrupt power supply to each of the device(s) for operation according to the image processing that has been instructed by the instruction component, the power supply control component being equipped with at least two measurement functions that have different measurement durations for cases in which the duration until interrupting the power supply to the device(s) is measured, wherein measurement is activated with a first measurement function of relatively long measurement duration at a completion time of prior image processing, and measurement is activated with a second measurement function of relatively short measurement duration for device(s) to which power is being supplied at the time of completion of the prior image processing but which are not required in later image processing.

2. The power supply control apparatus of claim 1 further comprising an adjustment component that adjusts the first measurement function and the second measurement function within a range between a first measurement duration for setting with emphasis on ease-of-use and a second measurement duration for setting with emphasis on power save effect.

3. The power supply control apparatus of claim 2, wherein the first measurement function is adjusted to the longest measurement duration and the second measurement function is adjusted to the shortest measurement function.

4. A power supply control apparatus comprising:

an instruction component for instructing image processing that selectively operates a plurality of devices;

an execution component that operates selected device(s) according to the image processing instructed with the instruction component and executes image processing;

a control component that controls so as to independently supply power or interrupt power supply to each of the device(s) for operation according to the image processing that has been instructed by the instruction component;

a first measurement component equipped with a first measurement function activated at a point in time when the image processing has been completed and measuring the duration until power supply is to be interrupted;

an extraction component that, when new image processing has been instructed while the first measurement component is still performing measurement, extracts device(s) that are employed in the prior image processing and will not be employed in the later image processing; and

a second measurement component equipped with a second measurement function activated for the device(s) that have been extracted by the extraction component, measuring the duration until power supply is to be interrupted, and having shorter measurement duration than the measurement duration by the first measurement component until power supply is to be interrupted.

5. The power supply control apparatus of claim 4 further comprising an adjustment component that adjusts the first measurement function and the second measurement function within a range between a first measurement duration for setting with emphasis on ease-of-use and a second measurement duration for setting with emphasis on power save effect.

6. The power supply control apparatus of claim 5, wherein the first measurement function is adjusted to the longest measurement duration and the second measurement function is adjusted to the shortest measurement function.

7. An image processing apparatus comprising:

an operation component equipped with an operating section for instructing image processing from one or other of a scanner function that reads in an original image using an image scanning component, a copy function that uses an image forming component to form an image on recording paper with image data scanned in by the image scanning component, a print function that uses the image forming component to form an image on recording paper with image data scanned in by the image scanning component or image data received by an image data transmission and reception component, a facsimile transmission function that externally transmits image data scanned in by the image scanning component using the image data transmission and reception component, a facsimile receiving function that uses the image forming component to form an image on recording paper with image data received by the image data transmission and reception component;

a control component that independently controls power supply and interruption of power supply to each device applicable to the image processing instructed by operation of the operation section of the operation component out of devices including the image scanning component, the image forming component and the image data transmission and reception component;

a first measurement component that is activated at a point in time when the image processing has been completed and measures a duration of time until power supply is to be interrupted;

an extraction component that, when new image processing has been instructed while measurement is still being performed by the first measurement component, extracts device(s) that are employed in prior image processing but will not be employed in later image processing; and

a second measurement component that is activated for the device(s) extracted by the extraction component and measures a duration until power supply interruption, the second measurement component having a measurement duration that is shorter than the measurement duration by the first measurement component until power supply is to be interrupted.

8. A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform as a power supply control apparatus that includes:

an instruction component for instructing image processing that selectively operates a plurality of devices;

an execution component that operates selected device(s) according to the image processing instructed by the instruction component and executes image processing; and

a power supply control component that controls so as to independently supply power or interrupt power supply to each of the device(s) operated according to the image processing instructed by the instruction component and is equipped with at least two measurement functions having different measurement durations for when the duration until interrupting the power supply to the device(s) is measured, wherein measurement is activated with a first measurement function of relatively long measurement duration at a completion time of prior image processing, and measurement is activated with a second measurement function of relatively short measurement duration for device(s) to which power is being supplied at the time of completion of the prior image processing but which are not required in later image processing.
