Abstract: PROBLEM TO BE SOLVED: To provide a sewing machine capable of driving a pressing member for pressing a cloth stably.SOLUTION: A position in which a body member 81 of a two-prong member 80 comes into contact with a first cam surface 71A of a composite cam 70 and a position in which an auxiliary member 82 comes into contact with a second cam surface 72A of the composite cam 70 are deviated from each other in an extention direction of a main shaft 17. Therefore, with respect to the two-prong member 80, a rotation moment easily occurs with a direction orthogonal to an oscillation center line of the two-prong member 80 being the center line. The first cam surface 71A and the second cam surface 72A are inclined with respect to the extention direction of the main shaft 17, so that the direction in which the body member 81 comes into contact with the composite cam 70 and the direction in which the auxiliary member 82 comes into contact with the composite cam 70 can be closer to each other. Therefore, the rotation moment occurring in the two-prong member 80 can be reduced, and a load applied on a pivot axis for pivotally supporting the two-prong 80 can be reduced, so that the two-prong member 80 can be oscillated stably. Thus, the sewing machine can favorably drive a cloth presser 38.SELECTED DRAWING: Figure 2

On the basis of the calculated reducible band, the decision part decides a reduction band to be reduced from the warrant bands. The allocation part allocates reserved band to an empty band obtained by reducing the decided reduction band from the warrant bands.SELECTED DRAWING: Figure 2
