Therefore, a sewing machine with this configuration is suitable for continuously sewing the same type of buttons, but if the button supply device malfunctions, the sewing machine will not be able to sew the buttons even if the sewing machine itself is normal. Buttons cannot be made using a sewing machine alone. Also, while sewing one type of button, it is necessary to sew another type of button (if you interrupt the process, you can sew a new button in the button supply device). In addition to exchanging with
Each part of the button supply device must be adjusted according to the size of the button, and furthermore, if the original type of button sewing is to be performed again after the interruption, the button must be replaced and the button must be replaced again. Adjustment work was required for each part of the feeding device. Replacing the J: eel button and adjusting the button supply device were extremely troublesome, and it was virtually impossible to interrupt the work to attach another type of button.

Purpose The present invention has been made in order to eliminate the drawbacks of the above-mentioned conventional devices, and its purpose is to provide a sewing machine with a button (in a sewing machine equipped with a button feeding device, normally a sewing machine with a button) The button feeding device is operated alternately to facilitate the continuous sewing of the same type of button, and if necessary, the button attachment can be operated by the sewing machine alone. The purpose is to provide a control device.
