Title: Ink-pot
Inventor: FURUYA KATSUYUKI
IPC: B25H7/04
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent a dangerous condition owing to flying of a marking thread end fixture when a marking thread is wound on a reel main body which is rotated by the urging force of a spiral spring. SOLUTION: A mass body 40 is connected to a part in the circumferential direction on the outer periphery of a reel main body 31, in the condition to allow the fluctuation of the mass body 40, in the radius direction of the reel main body 31 by making the axis 31a as the center. To the mass body 40, a sliding part 42 slidable with the inner peripheral surface 26 of a bobbin winding case 20 is formed. Since the center of gravity of the reel main body 31 is decentralized by the mass body 40, and when it is rotated in the bobbin winding direction by the energizing force of a spiral spring, a vibration is generated in the diameter direction following the rotation, it is fluctuated to the outer peripheral side by the centrifugal force of the mass body 40, and the sliding part 42 is slided with the inner peripheral surface of the bobbin winding case 20.  As a result, the increase of the rotating speed is suppressed, and the flying in of a marking thread end fixture 2 is prevented.
