Abstract: A moving body includes a housing, a traction motor, a plurality of elevator motors and a battery. The traction motor allows the housing to travel along a traveling surface. The plurality of elevator motors actuates an elevator unit, the elevator unit being configured to be elevated and lowered with respect to the traveling surface. The battery supplies electric power to the traction motor and the plurality of elevator motors. In the moving body, the plurality of elevator motors, the traction motor, and the battery are distributed when viewed perpendicularly to the traveling surface. The moving body further comprises at least one driving wheel to support the housing on the traveling surface. The plurality of elevator motors, the traction motor, and the battery fall, in a direction perpendicular to the traveling surface, within a range defined by a diameter of the at least one driving wheel.

Abstract: A shopping basket includes a main basket body configured to store a product therein and a bottom part attached to the main basket body to open and close a lower opening of the main basket body. When the bottom part closes the lower opening, the main basket body and the bottom part constitute an internal space which is surrounded by the main basket body and the bottom part and which communicates with the upper opening and the lower opening, and allow the internal space to store the product therein. When the bottom part opens the lower opening, the lower opening allows the product to be taken out of the internal space through the lower opening. When moving a product to a container, a user is not required to lift and take out the products one by one from an upper opening of the shopping basket.

Abstract: A support has a loading surface that is formed for placement of a merchandise. A guide is disposed around the support and along an outer circumference of the loading surface. A drive unit changes a disposition of a main mechanical unit from a first disposition to a second disposition. A level of the support relative to the guide in the second disposition is lower than the level of the support relative to the guide in the first disposition. The main mechanical unit in the first disposition supports a bottom of a bag with the loading surface, while the bag with a bag mouth facing downward is put on the support and the guide from above. The main mechanical unit puts the merchandise into the bag by allowing a side periphery of the bag contiguous to the bottom of the bag to stand upward from the bottom of the bag via the guide by changing the disposition of the main mechanical unit from the first disposition to the second disposition.
