Power output device, power input device, and power output/input device

A power input device including a casing, an internal load to which electric power is input from outside, the power input device comprising:

• a third terminal configured to receive DC power from outside;
• a fourth terminal configured to receive AC power from outside;
• a first device configured to receive from a user an input instruction of power from the third terminal;
• and
• a second device configured to receive from a user an input instruction of power from the fourth terminal,
• wherein the third terminal and the fourth terminal are arranged in a direction that is identical to a direction in which the first device and the second device are arranged, in a manner that order of arrangement of the third terminal and the fourth terminal is identical to order of arrangement of the first device and the second device, and
• the third terminal and the fourth terminal are installed in one recessed portion that is formed on the casing.

A power output/input device including in a casing, at least one of an internal power supply or an internal load, the internal power supply configured to output electric power to outside, electric power being input from outside to the internal load, the power output/input device comprising:

• at least one of
• a set including a first terminal, a second terminal, a first cap, and a second cap, or
• another set including a third terminal and a fourth terminal,
• wherein a load is to be connected to the first terminal, the load receives DC power from the power output/input device, a load is to be connected to the second terminal, the load receives AC power from the power output/input device, the first cap covers the first terminal, the second cap covers the second terminal, the third terminal is configured to receive the DC power from outside, and the fourth terminal is configured to receive the AC power from outside;
• a first device configured to receive from a user an output instruction of power from the first terminal or an input instruction of power from the third terminal;
• a second device configured to receive from a user an output instruction of power from the second terminal or an input instruction of power from the fourth terminal;
• an opening configured to provide communication between inside and outside of the casing;
• and
• a cover portion provided to the casing pivotably on a pivoting shaft to cover the opening,
• wherein the first device and the second device are arranged at the cover portion,
• the set including the first terminal and the second terminal is installed in one recessed portion that is formed by an indentation with respect to a surface of the casing on which the first device and the second device are provided, and
• the another set including the third terminal and the fourth terminal is installed in another recessed portion that is formed on the casing.

A power output device including an internal power supply in a casing, the internal power supply configured to output electric power to outside, the power output device comprising:

• a first terminal to which a load is to be connected, the load receiving an output power of a first type from the power output device;
• a second terminal to which a load is to be connected, the load receiving an output power of a second type that is different from the first type, from the power output device;
• a first device configured to receive from a user an output instruction of the output power of the first type from the first terminal;
• a second device configured to receive from a user an output instruction of the output power of the second type from the second terminal;
• and
• a third device that is a main switch configured to receive from a user a start-up instruction of the power output device,
• wherein the first device, the second device, and the third device are arranged in one direction on a same plane, and
• the first terminal and the second terminal are arranged in a direction that is identical to a direction in which the first device, the second device, and the third device are arranged, in a manner that order of arrangement of the first terminal and the second terminal is identical to order of arrangement of the first device and the second device.
