Abstract: A reconfigurable inner support structure for holding and displaying an article. The inner support structure includes at least two parts having positions or angles changeable relative to each other. Reconfiguration of the inner support structure refers to a transformation between a manufacturing configuration and a use configuration, and is formed by a change in the relative position or angle between the at least two parts of the inner support structure. In the manufacturing configuration, the inner support structure is free of an undercut structure. In the use configuration, the inner support structure includes an undercut structure for securing an article and preventing the article from being removed from the inner support structure.

Abstract: The present invention simplifies the configuration of a rotary encoder. In the present invention, a plate spring 3, which includes a plurality of arm sections 3BX to 3FX where curving projection sections 3BZ to 3FZ are formed and whose tips are movable contacts 3BX to 3FX, is attached to a base 2 including a plurality of fixed contacts 6 to 10. In addition, a gear 4, whose one surface's concentric positions are equipped with a plurality of curving-line-shaped projection sections 4C to 4G, is attached so that it can rotate. When the gear 4 rotates, the curving-line-shaped projection sections 4C to 4G push the curving projection sections 3BZ to 3FZ and the movable contacts 3BX to 3FX of the arm sections 3B to 3F touch the fixed contacts 6 to 10. Accordingly, since there is no component between the gear 4 and the plate spring 3 to push down the arm sections 3B to 3F, the configuration of the rotary encoder 1 can be simplified.
