    • A reel driving device includes a reel stand for driving a reel to rotate; and a latch including at least one contact portion contactable with the reel. The reel stand includes a convexed and concaved portion. The latch includes a claw portion for, when contacting the convexed and concaved portion, stopping a rotation of the convexed and concaved portion. While the reel stand rotates in a first direction, the latch moves in such a direction that the claw portion contacts the convexed and concaved portion by a rotation of the reel stand being conveyed to the at least one contact portion. While the reel stand rotates in a second direction, the latch moves in such a direction that the claw portion is separated from the convexed and concaved portion by a rotation of the reel stand being conveyed to the at least one contact portion.
    • 卷轴驱动装置包括用于驱动卷轴旋转的卷轴架; 以及闩锁,其包括可与卷轴接触的至少一个接触部分。 卷盘架包括一个凸形和凹形的部分。 闩锁包括爪部,用于当与凸部和凹部接触时,停止凸部和凹部的旋转。 当卷轴架沿第一方向旋转时,闩锁沿着被传送到至少一个接触部分的卷轴架的旋转的方式使爪部分接触凸形和凹形部分的方向移动。 当卷轴架沿第二方向旋转时,闩锁沿着使托盘部分被转移到至少一个接触部分的旋转方向从爪部分与凸形和凹形部分分离的方向移动。
