Abstract: The present invention relates to a two-bin magazine assembly. Two adjacent imaginary bullets disposed at the innermost position of the two-bin magazine main body prior to bullet loading are connected in one set by a pair of links, a spacer is disposed between the pair of links so as to maintain a separation distance of the adjacent imaginary bullets at a constant distance, a connecting arm connecting the one set of the adjacent and connected imaginary bullets to one set of two connected imaginary bullets following between one of the links and one side of the spacer is disposed in a zigzag manner, and thus imaginary bullet tangling is prevented. The warhead of the imaginary bullet is formed in a semicircular shape, and thus friction is reduced. A hemispherical projection having a semicircular cross section is formed on a bottom surface and a wall surface in contact with the bullet in the two-bin magazine main body for a smooth bullet movement in the two-bin magazine main body, and thus the bullet and the magazine main body are in point contact with each other for reliably frictional coefficient reduction. In addition, a hemispherical projection having a hemispherical cross section is formed at the part of a linear magazine coming into contact with a bullet, and thus point contact is performed between a magazine and a bullet. As a result, bullet transport is facilitated in the two-bin magazine main body and the linear magazine during a movement during bullet loading and a movement for reloading. As a result, no dust is generated in the two-bin magazine main body and the linear magazine, and thus the health of a gun user can be promoted and magazine cleaning can be facilitated.

Abstract: In general, a table tennis room requires a table tennis mesh net in order to prevent a table tennis ball from rolling far away. The present invention relates to a table tennis mesh net capable of preventing a table tennis ball from rolling far away in a table tennis room. To be more specifically, the table tennis mesh net allows the table tennis ball to pass the mesh net when a player puts the ball into the mesh and pushes the ball by hands because the circumference of the mesh is circumscribed to the table tennis ball. The mesh net in the present invention has a vertically long diamond-shaped mesh due to the weight thereof by being hung on a string in a table tennis room. In addition, the table tennis ball must pass the central part of the mesh in order to pass the mesh but it is very difficult for the table tennis ball to overcome friction force and pass the mesh. Accordingly, the table tennis mesh net, of which the circumference of the mesh circumscribes the table tennis ball, can be appropriate for being used as a table tennis mesh net because the table tennis ball normally cannot pass the mesh net. Furthermore, the table tennis mesh net can be very convenient as a table tennis mesh net in a table tennis room by allowing players to easily give and take the table tennis ball through the mesh because the table tennis ball can easily pass the mesh by being put in the mesh and pushed by hands.
