<p><P>PROBLEM TO BE SOLVED: To provide a bobbin case removing and attaching mechanism for a loop taker which achieves easy removal and attachment of a bobbin case by removing only a needle plate, in which the bobbin case is inserted into a predetermined operating position at a loop taker when the bobbin case is attached to the loop taker, and the bobbin case is always retained at the predetermined operating position even under a vibration or other forces generated upon sewing (for example, a force generated when a sewing machine is carried or transferred, and the like), and which is obtained at low costs. <P>SOLUTION: The bobbin case removing and attaching mechanism for the loop taker includes: the bobbin case 2; a loop taker 1 provided with a bobbin case accommodating space 13 into which the bobbin case 2 is inserted; a bracket 4 fixed at a bobbin case fixing plate 3 of the sewing machine the bracket including an opening 45 through which the bobbin case 2 passes when the bobbin case 2 is inserted into or removed from the bobbin case accommodating space 13; and a needle plate 5 closing at least a portion of the opening 45, the needle plate including a bobbin case stopper piece 6 which restricts an upward movement of the bobbin case 2 when the bobbin case is inserted into the predetermined operating position of the bobbin case accommodating space 13. The bobbin case 2 is removed from or attached to the bobbin case accommodating space 13 in a state where the needle plate 6 is removed from the bracket and the bracket 4 is fixed to the bobbin case fixing plate 3, and the bobbin case 2 is retained at an operating position of the bobbin case accommodating space 13 by the bracket 4 and the bobbin case stopper piece 6. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
