Embodiment Construction

[0037] figure 1 It is a perspective view showing the appearance of the hybrid PC 100 . The hybrid PC 100 is composed of a tablet unit 120 and a base unit 110 formed of casings that can be physically separated and combined with each other. figure 1 (A) shows a tablet-type PC 100 composed of a combination of a tablet unit 120 and a base unit 110 , figure 1 (B) shows the base unit 110 when detached, figure 1 (C) shows the flat panel unit 120 when it is separated. in the future appropriately figure 1 The state of (A) is called the bound state, and the figure 1 The states of (B) and (C) are called separated states.

[0038] The surface of the tablet unit 120 is equipped with a touch panel 105 including a display and a touch sensor, and a system device that functions as a tablet terminal in a separated state is mounted inside the casing. The base unit 110 is constituted by the system housing 101 and the support member 103 coupled to each other by the hinge unit 111 . Th...

Abstract

The present invention relates to an electric power system, an electronic device and a charging method, which can reduce the number of connectors for connecting a tablet unit and a base unit. The tablet unit (120) includes a system device (161) and a connector (175) connected to a power line (177) for supplying power from the base unit (110). The base unit (110) includes a connector (275) configured to be connected to the connector (175) when the base unit is combined with the tablet unit; a battery unit (165) capable of supplying power to the system device (161) through the power line (177), and an external power-supply circuit capable of supplying power to the system device from an AC / DC adapter (252) through the power line. Since power can be supplied from the battery unit or the AC / DC adapter to the tablet unit through the power line alone, the number of connector terminals can be reduced.

Description

technical field [0001] The present invention relates to a technique for reducing the number of power terminals of a connector that connects two units such as a portable electronic device and a function expansion device, and particularly relates to charging a battery installed in another unit with a battery installed in one unit technology. Background technique [0002] Portable electronic devices include notebook personal computers (notebook PCs), tablet terminals, and smartphones. Notebook PCs have complex functions that can be used for all operations. Input devices such as mice and keyboards are suitable for operations that input large amounts of data. However, they are not portable due to higher power consumption compared to tablet terminals, size, and weight. [0003] In contrast, although tablet terminals and smart phones have simpler functions than notebook PCs, they are convenient and fast in browsing web pages, moving images or executing applications through the tou...
