Electronic device, method for controlling electronic device, and recording medium

An electronic device switching an operating mode to a power saving mode when predetermined time elapses, the electronic device comprising:

• a data storage unit storing mode set time which is waiting time taken until the operating mode is switched to the power saving mode;
• an extension processing unit extending the mode set time by predetermined time and stores the extended mode set time in the data storage unit when an extension directing operation is carried out after end of an image formation process and before elapse of the mode set time;
• a mode control unit switching the operating mode of the electronic device to the power saving mode when the mode set time elapses after end of the image formation process;
• and
• a recovery processing unit returning the mode set time to a reference value after the operating mode is switched to the power saving mode by the mode control unit.

A method for controlling an electronic device comprising:

• a control unit connected to a process executing unit executing a directed information process, a set time data storage unit recording data about mode set time taken until transition to a power saving mode consuming small power after the information process in the process executing unit is finished, a basic set time data storage unit recording data about basic set time, an extension time data storage unit recording data about extension time, and an operation unit;
• wherein
• the control unit executes:
• a mode control step of measuring the time elapsed from end of the information process and, when the elapsed time passes over the mode set time recorded in the set time data storage unit, causing the process executing unit to transition to the power saving mode;
• an extension processing step of, when an extension direction of the mode set time is detected via the operation unit, calculating extended mode set time by using the extension time recorded in the extension time data storage unit and recording the calculated mode set time in the set time data storage unit;
• and
• a recovery processing step of, when transition to the power saving mode is made in the case in which the extended mode set time is stored in the set time data storage unit, recording the basic set time, which is recorded in the basic set time data storage unit, in the set time data storage unit.

A control method of an electronic device switching an operating mode to a power saving mode when predetermined time elapses, the control method of the electronic device comprising:

• a step of storing mode set time which is waiting time taken until the operating mode is switched to the power saving mode;
• an extension processing step of extending the mode set time by predetermined time and storing the extended mode set time when an extension directing operation is carried out after end of an image formation process and before elapse of the mode set time;
• a mode control step of switching the operating mode of the electronic device to the power saving mode when the mode set time elapses after end of the image formation process;
• and
• a recovery processing step of returning the mode set time to a reference value after the operating mode is switched to the power saving mode in the mode control step.

A recording medium storing a control program of an electronic device comprising a control unit connected to a process executing unit executing a directed information process, a set time data storage unit recording data about mode set time taken until transition to a power saving mode consuming small power after the information process in the process executing unit is finished, a basic set time data storage unit recording data about basic set time, an extension time data storage unit recording data about extension time, and an operation unit;

• wherein
• the recording medium stores a program for causing the control unit to function as:
• a mode control unit which measures the time elapsed from end of the information process and, when the elapsed time passes over the mode set time recorded in the set time data storage unit, causes the process executing unit to transition to the power saving mode;
• an extension processing unit which, when an extension direction of the mode set time is detected via the operation unit, calculates extended mode set time by using the extension time recorded in the extension time data storage unit and records the calculated mode set time in the set time data storage unit;
• and
• a recovery processing unit which, when transition to the power saving mode is made in the case in which the extended mode set time is stored in the set time data storage unit, records the basic set time, which is recorded in the basic set time data storage unit, in the set time data storage unit.
