PURPOSE:To aim at making a cylindrical body attachable or detachable to and from the desired position of a barrel cell in an accurate and easy manner, by constituting the cylindrical body available for media rejection from the central part of the barrel cell so as to cause its lower part clinging to the bottom of the barrel cell to be opened. CONSTITUTION:A strut 21 is erected at the central part of a barrel cel 10 while a cylindrical body 23 is set to this strut 21 in coaxial form in addition. The cylindrical body 23, which is for rejecting media 24 from the central part of the inside of the barrel cell 10, opens its lower part while closing its topside and desirably its lower peripheral parts are thinly formed in thickness, then guide plates 25a and 25b each having through holes to insert the strut 21 through are installed at two spots, top and bottom in the inside. With this constitution, when the cylindrical body 23 is replaced, a possibility of inserting these media between both plates is seldom or never, so that the cylindrical body 23 can be attached or detached to and from the desired position of the barrel cell 10 in a regular state so accurately and easily. |
