To take out heat pipe containers one by one from a container group and carry the heat pipe containers by providing a storing unit provided with grooves storing the heat pipe containers one by one on a belt conveyor and arranging the container group in which the heat pipe containers are stocked by bringing the container group into contact with a belt conveyor track.

A storing unit 22 in which grooves 220 storing heat pipe containers 23 one by one are formed is mounted on a belt 20 which is put on a first sprocket 210 and a second sprocket 211 located on the obliquely upper side. A belt conveyor 2 is revolved, and heat pipe containers 23 are successively stored one by one in the grooves 220 from a container group 230 held by the belt conveyor 2, an inclined base 25 and an external body 251, are taken out and are carried to the upper side by the belt 20. When the heat pipe containers 23 passes the second sprocket 211 at this stage, the heat pipe containers 23 stored in the grooves 220 fall by gravity to a supply setting part 24.
