Description

This invention relates to electronic equipment, a control method for electronic equipment, and a program. Traditionally, electrical appliances have featured mechanisms that automatically shut off the power when not in operation to reduce power consumption. From the perspective of contributing to the mitigation of global warming, power saving is an important function. Furthermore, in recent years, various countries have implemented laws and regulations related to power saving, and electrical appliances are increasingly required to comply with the laws and regulations of the regions where they are sold. Patent Document 1 discloses a technology for switching the time between when the printer becomes inactive and when it is powered off, depending on the type of power supply (AC adapter connection or battery connection).

The present disclosure will be described in detail below with reference to the drawings. Note that the following embodiments are not intended to limit the scope of the claims, and not all combinations of features described in these embodiments are necessarily essential to the solutions of the present disclosure. Furthermore, in the accompanying drawings, identical or similar components are given the same reference numerals, and redundant descriptions are omitted. (First embodiment) Figure 1 is a block diagram illustrating the schematic configuration of an MFP 100, which is one embodiment of the electronic device of the present invention. In the MFP 100, the CPU 101 is the system control unit and controls the entire MFP 100. The ROM 102 stores fixed data such as control programs, data tables, and embedded operating system (OS) programs executed by the CPU 101. In this embodiment, each control program stored in the ROM 102 performs software execution control such as scheduling, task switching, and interrupt processing under the management of the embedded OS stored in the ROM 102. The RAM 103 is composed of SRAM (Static Random Access Memory) or the like, which requires a backup power supply, and the data is held by a primary battery for data backup (not shown). The RAM 103 stores program control variables and the like, whose data should not be erased. A memory area is also provided to store user-registered settings and management data for the MFP 100. For example, user-registered settings include network settings, and a memory area is provided to store the enable/disable status of wired LAN, Wi-Fi, and wireless direct. These settings are manually configured by the user using the display operation unit 108, which will be described later. After powering on the MFP 100, the LAN settings screen is displayed on the display operation unit 108 (not shown) by selecting the settings menu, main unit settings, and LAN settings in that order. These settings can then be configured. Furthermore, in this embodiment, a memory area is provided to store setting information for "Automatic Power Off (LAN/USB Connection)" and "Automatic Power Off (LAN/USB Not Connected)" (six types: none, 15 minutes, 30 minutes, 60 minutes, 120 minutes, 240 minutes). Initial values are stored as "Never" for "Automatic Power Off (LAN/USB Connection)" and "15 minutes" for "Automatic Power Off (LAN/USB Not Connected)". Thus, in this embodiment, by setting a predetermined time as the initial value for the "Automatic Power Off (LAN/USB Not Connected)" setting, it becomes possible to comply with regulations requiring automatic power off within a specified time in standalone mode. The image memory 104 is composed of DRAM (Dynamic Random Access Memory) and other components, and stores image data. A portion of this area is reserved as a work area for executing software processing. The data conversion unit 105 performs image data conversion, including analysis of page description languages (PDL) and computer graphics (CG) conversion of character data. The reading control unit 106 processes the image signal, which has been optically read by the reading unit 107 using a CIS image sensor and converted int
