PROBLEM TO BE SOLVED: To provide a sewing machine capable of easily and temporarily changing the feed amount of a cloth and returning the same in the state where the drive of a main shaft motor is stopped.SOLUTION: A CPU of a sewing machine determines whether a stepping-on of a pedal is detected (S13). When the stepping-on of the pedal is detected (S13:YES), the CPU drives a cloth feed motor under a first condition which is a drive condition of the cloth feed motor for feeding a cloth in a predetermined feed amount in synchronization with the rotation of a main shaft. When the stepping-on of the pedal is not detected (S13:NO), the CPU specifies a feed amount on the basis of operations of a first button and a second button (S14). The CPU determines a second condition which is a drive condition of the cloth feed motor for feeding a cloth in the specified feed amount (S21). The CPU changes the drive condition of the cloth feed motor from the first condition to the second condition. The CPU drives the cloth feed motor under the second condition and the cloth feeding mechanism feed cloth in the amount specified in S14. |
