Abstract
A sewing apparatus is provided with an X-Y unit 4 for horizontally moving a cassette in relation to a sewing machine 3, memory 23 for holding sewing data for driving the X-Y unit 4 in accordance with a sewing pattern and feeding data for feeding only the cassette without entailing stitching action, a drill 10 for grooving a slot in the cassette, a vertical drive mechanism 18 for vertically moving the drill 10, and a CPU 22. The drill 10 is moved downward while rotating, and the X-Y unit 4 is actuated on the basis of the sewing data to form the slot. After the drill 10 has become deactivated and moved upwards, the cassette is fed on the basis of the feeding data. Since the CPU 22 executes the rotation and downward movement of the drill 10 at the time of grooving and the upward movement and interruption of rotation of the drill 10 at the time of feeding, switching operation required to rotate, move downward, move upward and to stop the drill 10 becomes unnecessary.
