Abstract
A cutting head is provided also with a notching blade to enable it to cut a length shorter than the blade width of a round blade. In order to eliminate the need for compressed air supplying equipment and simplify the mechanism thereby to make it compact and light weight, an angular displacement servo motor is used as a common drive source for causing angular displacement of the round blade and angular displacement of the notching blade. A cam motor causes a round blade cam and a notching blade cam to make angular displacement thereby to selectively cause the round blade and the notching blade to work on sheet material placed on a cutting table an cut it.
