Sewing machine

A sewing machine comprising;

• a sewing head having a sewing needle to be vertically reciprocally driven;
• a shuttle base having a shuttle to be rotatably driven in synchronism with the vertical movement of the sewing needle for forming stitches;
• and
• a machine frame including a pair of support posts spaced laterally from each other, an upper frame for mounting the sewing head thereon, and a lower frame disposed below said upper frame for mounting the shuttle base thereon;
• each of said upper frame and said lower frame extending between said pair of support posts and being fixed thereto;
• a stay extending between said pair of support posts and fixed thereto;
• and
• a table supported on said stay for placing thereon a holder frame of which a work to be sewn is set.

A sewing machine comprising:

• at least one sewing head having a sewing needle to be vertically reciprocally driven;
• at least one shuttle base having a shuttle to be rotatably driven in synchronism with the vertical movement of the sewing needle for forming stitches;
• and
• a machine frame for mounting said at least one sewing head and said at least one shuttle base thereon;
• said at least one shuttle base being mounted on said machine frame via an associated vibration absorbing member;
• said vibration absorbing member having a flat plate-like configuration and having upper and lower surfaces;
• said at least one shuttle base having a first flat plate mounted thereon;
• said frame having a second flat plate mounted thereon;
• said vibration absorbing member being interposed between said first flat plate and said second flat plate, so that said upper surface and said lower surface of said vibration absorbing member contact said first flat plate and said second flat plate in surface-to-surface contacting relationship therewith.

A sewing machine comprising:

• a multi-needle type sewing head having a plurality of sewing needles, one of said sewing needles being selected to be vertically reciprocally driven;
• a shuttle base having a shuttle to be rotatably driven in synchronism with the vertical movement of the selected sewing needle for forming stitches;
• and
• thread passage means disposed above the sewing head for supplying threads to said sewing needles;
• said thread passage means including a thread passage member having guide slits formed therein in the same number as the sewing needles, and a presser adapted to be pressed on said thread passage member, so that all the threads to be supplied to said sewing needles are held and released at one time by pressing and releasing said presser.
