PROBLEM TO BE SOLVED: To provide a space-saving configuration which switches many drive paths.SOLUTION: A drive switching unit includes a drive gear 132 which is rotated by a motor that rotates forward/backward, a first swing gear 133, and a second swing gear 134. The first and second swing gears 133, 134 are engaged with the drive gear 132, and swing around a rotation center of the drive gear 132, according to a rotation direction of the drive gear 132. When the drive gear 132 is rotated in an arrow A direction, the first swing gear 133 is connected to a first gear train 138a, and the second swing gear 134 is connected to a second gear train 138b, respectively. When the drive gear 132 is rotated in an arrow E direction, the first swing gear 133 is disconnected from the first gear train 138a, the second swing gear 134 is disconnected from the second gear train 138b, and the second swing gear 134 is connected to a third gear train 138c. |
