摘要： A presser foot device includes a wall portion, a pair of opposed portions, a pin, and an abutting portion. The wall portion extends in a first direction and a second direction intersecting the first direction. The pair of opposed portions extend in one direction of a third direction intersecting the first direction and the second direction from the wall portion, and face each other. The pin extends in the second direction between the pair of opposed portions, and engages with a groove provided in the presser foot holder. The abutting portion is provided with respect to the pin on one direction side of the first direction, and is provided on the one direction side of the third direction of an end surface in the one direction of the third direction, of the pair of opposed portions. The abutting portion abuts against the pressor foot holder in the second direction.

摘要： A music box includes a star wheel, a stopper, a sun wheel, a motor, a sensor, and a controller. The star wheel is configured to rotate about a first shaft. The sun wheel is fixed on a second shaft and engages the star wheel. The motor is configured to rotate the first shaft and the second shaft. The sensor is configured to detect a rotation state of the sun wheel. The controller is configured to: read a music data; control the motor to rotate at a rotational speed based on a temp; determine a start timing at which the stopper starts to release the star wheel based on a sound output timing and the rotation state; calibrate the start timing to a calibrated start timing based on a value related to the rotational speed; and control the stopper to release the star wheel at the calibrated start timing.
