Abstract
The present invention relates to a 3D card in which a horizontal fold line is provided between a card center portion and a card bottom surface, a lower fold line is provided between the card bottom surface and a lower blocking surface, vertical fold lines are provided between left and right sides of the card center portion, left and right blocking films, and a lens plate, respectively, and an upper fold line is provided between an external light window and the upper blocking surface, so that the card bottom surface rotates from a lower portion to front and rear surfaces of a card, thereby forming a single card or a three-dimensional device.

1-2. (canceled)
A 3d card, comprising:
- a single sheet card (1) having a front surface and a rear surface,
- wherein the front surface is configured to display a continuous image;
- an upper blocking surface (6) formed on an upper portion of the rear surface of the card (1);
- an upper fold line (8) formed along one side of the upper blocking surface (6);
- a reinforcement member (2a) extending from the upper fold line (8) and defining a light incident passage;
- an external light window (2) formed in the reinforcement member (2a) and configured to introduce external light into the card;
- a three-dimensional image (3) disposed at a central portion of the rear surface of the card (1);
- a lens plate (5) disposed in front of the three-dimensional image (3) such that external light introduced through the external light window (2) is directed toward the three-dimensional image (3) through the lens plate (5);
- and
- a lower fold line (9) formed at a lower portion of the card (1),
- wherein:
- folding of the card (1) along the upper fold line (8) and the lower fold line (9) forms a light-shielding chamber between the reinforcement member (2a) and the rear surface of the card (1);
- the light incident passage defined by the reinforcement member (2a) establishes an optical path from the external light window (2) to the three-dimensional image (3);
- and
- unfolding of the card (1) changes a relative positional relationship between the lens plate (5) and the three-dimensional image (3) to permit observation of the three-dimensional image (3) through the lens plate (5).
