A cartridge 190 is detachably attached to the holder 110. The cartridge 190 moves along a protrusion 3 while the holder 110 and cartridge 190 rotate around the central axis 120c, and thereby the cartridge 190 moves with respect to the holder 110 along a direction where a line connecting the holder 110 to the cartridge 190 extends, and the cartridge 190 is attached to and detached from the holder 110. |
