PROBLEM TO BE SOLVED: To enable working-hour reduction and natural-looking pattern positioning operation required for positioning a pattern. SOLUTION: In positioning E of the pattern in a variable pattern, a position correcting pattern for rotatably moving a pattern display body at a required positioning speed is selected and set, and a moving distance corresponding to a dislocation quantity of a step unit caused in driving of a motor is obtained in a specific time. This position correcting pattern is constituted by combining plural positioning speeds, and when rotatably moving the pattern display body preset time by preset time with respective positioning speeds, finely adjusting processing is always completed in a specific time. The positioning speed is set in the same or almost the same as a high speed D, and the pattern can be positioned in a short time. |
