15, the button holding member 5 of the sewing machine 2 is raised and rotated to a position suitable for receiving the button B, and then the rotating cam 11
6, the button carrying body 12 moves to the 10th and 11th positions.
The button B on the button delivery body 12 is delivered onto the button holding member 5 by being rotated from the receiving position shown by the solid line in the figure to the delivery position shown by the chain line. or,
In this state, the button holding member 5 is further rotated upward by the action of the second lifting cam portion 115b of the lifting cam 115, and the button B on the holding member 5 is rotated upwardly.
is pulled out from the insertion part 14 of the button carrying body 12.

After that, the motor 112 of the reciprocating mechanism 110
is rotated in the opposite direction, the button delivery body 12 is rotated back from the delivery position to the receiving position, and the operation of supplying one button B to the button holding member 5 of the sewing machine 2 is completed. And by repeating this action,
The buttons B sent out from the button supply part body 7 are smoothly and accurately supplied one by one onto the button holding member 5 of the sewing machine in a short time.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and the configuration of each part can be arbitrarily changed and embodied without departing from the spirit of the invention.

Effects of the Invention As detailed above, the present invention provides a button individual feeding mechanism, an elevating mechanism for a button position correction member,
The rotation mechanism for the correction member and the reciprocating mechanism for the button carrier are each driven by a plurality of drive means each driven in response to a predetermined signal, and their operation timings can be freely set. It is possible to shorten the time required for one button to be supplied from the button supply unit to a predetermined sewing position of the button sewing machine, and to shorten the timing of intermittent supply of buttons. This has the excellent effect of improving the sewing efficiency of the sewing machine.
