• a first transport mechanism that transports the carriage in the first direction,
• a rotation mechanism that causes the embroidery frame to rotate,
• a first motor that drives the first transport mechanism and the rotation mechanism, and
• a first shaft that extends in the first direction and supports the carriage, and that transports the carriage in the first direction when the first shaft rotates as a result of driving of the first motor,
• the rotation mechanism includes:
• a second shaft that is arranged in parallel to the first shaft, that movably supports the carriage and that rotates as a result of the driving of the first motor, and
• a first gear that is arranged around the second shaft, the first gear rotating in accordance with rotation of the second shaft, and moving in the first direction in concert with the carriage that is transported by the first shaft,
• the carriage includes a third gear that meshes with a second gear formed around an outer peripheral surface of the embroidery frame and with the first gear, and
• the embroidery frame is rotated by rotation of the second gear via the first gear and the third gear, when the second shaft rotates as a result of rotation of the first motor.
