    • An ink jet recording apparatus (100) includes a shaft (2g) for receiving rotational driving force; a clutch gear (4) mounted on the shaft rotated by rotation of the shaft and movable in a longitudinal direction of the shaft; a transmission gear (21) engageable with the clutch gear in accordance with movement and rotation of the clutch gear, wherein a predetermined mechanism is operated by rotation of the transmission gear by engagement with the clutch gear; the clutch gear including; a flange (4a) disposed at a position engageable with a portion of the transmission gear to prevent rotation of the transmission gear before the movement of the clutch gear for the engagement with the transmission gear; a starting tooth (4c1) for engagement with a predetermined tooth of the transmission gear in accordance with the movement and the rotation; and a non-engagement portion (4b) faced to the transmission gear before the engagement of the starting teeth.
    • 喷墨记录装置(100)包括用于接收旋转驱动力的轴(2g) 安装在所述轴上的离合器齿轮(4),所述离合器齿轮(4)通过所述轴的旋转而旋转并且可沿所述轴的纵向方向移动 根据所述离合器齿轮的运动和旋转与所述离合器齿轮啮合的传动齿轮(21),其中通过与所述离合器齿轮啮合而通过所述传动齿轮的旋转来操作预定机构; 该离合器齿轮包括: 设置在与传动齿轮的一部分可接合的位置处的法兰(4a),以防止传动齿轮在用于与传动齿轮接合的离合器齿轮的运动之前旋转; 根据运动和旋转而与传动齿轮的预定齿啮合的起动齿(4c1) 以及在接合起始齿之前面向传动齿轮的非接合部分(4b)。
