When the sewing machine is started, the piston rod 26 is retracted, the positioning member 27 is lifted upwardly, and the body is sent to the back placket sewing section 21 by the roller assembly 23 and sewn in the usual manner.

A thread cutter mechanism 30 is provided for cutting the sewing thread after sewing. As shown in FIG. 6, this thread cutter mechanism has a cutter 31 and a table 32 on which the thread is placed, which is fixed on the table 20 and faces the cutter. The cutter 31 is attached to one end of a lever 33, and the intermediate portion of this lever is pivotally connected to a rod 34 fixed to the table 20.

The other end of the lever is driven by a cylinder 35.

That is, when the piston rod 36 of this cylinder is extended, the cutter 31 comes into contact with the table 32 and cuts the thread on this table. Note that a spring (not shown) is provided that biases the lever 33 so that the cutter 31 always moves away from the stand 32.

This cutter mechanism can automatically cut the thread after the sewing machine 10 finishes sewing. Conventionally, this optical cutting was performed by a worker, so this cutter mechanism makes the work easier and more convenient.

As is well known, the button sewing machine 11 includes a table 40, a button supply means 41, and a button sewing section 42. This button sewing machine 11 also has an indexer 43 that feeds the body intermittently. This indexer is the second
