Claims

[Claims for Utility Model Registration] The sewing machine is rotatably supported on the frame 15 of the sewing machine.
Start/stop means 21.24. for controlling the connection and disconnection between the main drive shaft 20 and the power source of the main drive shaft 20, and for stopping the main drive shaft 2.0 in a fixed position after the main drive shaft 20 is disconnected. 27,2
9, 30, etc.; a cam contactor 64 interlocked with the start/stop means 21, 24, 27, 29, 30, etc.; and a cam contactor 64 interlocked with the main drive shaft 20 to be rotated at a reduced speed. Engaging with the front cam contactor 64, the activation/stopping means 21.
24, 27, 29, 30, etc., in the activation device during one sewing cycle, and after the completion of one sewing cycle, the activation/stop means 21, 24. ．． 27. '29, 30 etc. to a stop position; a control cam 61 that moves reciprocally once per rotation of the main drive shaft 20 in conjunction with the main drive shaft 20, and a first locking portion; 7, a reciprocating drive body 75 provided with 7, and a cloth which is movably disposed across the vertical movement path of the needle 44, on the bead surface of the limiter, and which is always urged toward the bed surface. a presser foot 48; a presser foot lifting member 56 supported on the frame 15 for raising the presser foot 48; one end operatively connected to the presser foot lifting member 56, and the other end connected to the reciprocating drive body 7. It extends so as to face .5 and 7,
and a reciprocating driven body 65 provided with a second locking part 78 that can engage with the first locking part 77 of the reciprocating drive body 75 at the other end, and the reciprocating driven body 65 and the cam. When the cam contactor 64 is moved to the sewing machine stop position, the reciprocating driven body 65 is moved to its second position.
The locking portion 78 is the first locking portion 77 of the reciprocating drive body 15.
When the cam contact 64 is moved to the sewing machine starting position, the driven body 6
-mechanical interlocking means 63 for moving 5 in the opposite direction. Equipped with '67~69.72',
. , the mechanical interlocking means are
- a lost contamination function to allow the cam contactor 64 to be moved to the sewing machine stop position irrespective of engagement of both the locking parts 77, 78, and the reciprocating drive after the lost motion; A cycle characterized in that it has a biasing means 72 that acts on the reciprocating driven body 65 so as to cause the engagement when both the locking parts 77 and 78 are brought into alignment with the reciprocating movement of the reciprocating member 75.
