Claim 17:
18. A sewing machine capable of sewing an embroidery pattern on a sewing object, the sewing machine comprising:
a movement mechanism configured to hold and move an outer frame of an embroidery frame in a state in which the sewing object is clamped between the outer frame and an inner frame of the embroidery frame;
a processor; and
a memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform processes comprising:
acquiring reference point coordinates representing a position of a reference point provided in a range prescribed by the inner frame of the embroidery frame;
notifying a notification position, using a notification portion, with respect to the range prescribed by the inner frame of the embroidery frame held by the movement mechanism;
acquiring a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notified notification position and the position of the reference point provided in the range prescribed by the inner frame of the embroidery frame in the state of being held by the movement mechanism; and
deciding, on the basis of a relationship between the acquired movement amount and the acquired reference point coordinates, a deviation from a prescribed state of a positional relationship between the inner frame of the embroidery frame and the movement mechanism holding the outer frame.
