A tape sealing means is known, in which a housing tape member is made to run and a large number of small, lightweight articles are sequentially packaged.

In addition, as a different type of automatic packaging device for small and light articles, an article mounting means is used which holds the above-mentioned small and light articles by suction under negative pressure and transports them from the take-out position into the article storage section of the storage tape member. arranged to support a small, lightweight article at a position above the article accommodating portion of the accommodating tape member without
For example, a plate-shaped movable article support section, an article supply means for transferring small and light articles onto the movable article support section, and a tape member for moving the movable article support section and accommodating the small and light articles supported by the movable article support section. It is composed of an article placing means for dropping and placing the article in the article accommodating part, and a tape sealing means, and similarly to the above-mentioned one, the accommodation tape member is made to travel and a large number of small and lightweight articles are sequentially packaged. A similar method has also been proposed.

Problems to be Solved by the Invention However, in the conventional automatic packaging device for small and lightweight articles as described above, the small and lightweight articles are held under negative pressure and transported from the take-out position into the article storage section of the storage tape member. In the case where an article placement means is used, the operating space required for the article placement means to convey small and lightweight articles is relatively large, resulting in a large device, or the configuration of the device is There is a disadvantage that it becomes complicated, and in the case where a movable article support part is provided to support the small and lightweight article at a position above the article storage part of the storage tape member, it is difficult to support the small and lightweight article. For packaging, first, the movable article supporting section is moved to a position above the article accommodating section of the accommodating tape member, and a small lightweight article is placed thereon, and then,
