    • PROBLEM TO BE SOLVED: To provide a paper conveying device capable of preventing a disk to be detected from being cut off or damaged even if a helical gear is used. SOLUTION: This paper conveying device comprises a conveying roller shaft 27 rotatably supported by a frame 21, a motor 41 for rotatingly driving the conveying roller shaft 27 through the helical gear 34 fitted to the conveying roller shaft 27, the disk 35 to be inspected fitted to the conveying roller shaft 27, and a sensor body 37 fitted to the frame 21 and detecting the rotation of the disk 35 to be detected. The paper conveying device further comprises a coil spring 40 for pressing the conveying roller shaft 27 to the reference end 30c of the frame 21 by biasing it in the thrust direction. The biasing force of the coil spring 40 is larger than a thrust force by the helical gear 34. The coil spring 40 is disposed coaxially with the conveying roller shaft 27. The conveying roller shaft 27 extends through the coil spring 40. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供一种即使使用斜齿轮也能够防止检测盘被切断或损坏的纸张输送装置。 解决方案:该纸张输送装置包括由框架21可旋转地支撑的输送辊轴27,用于通过装配到输送辊轴27的螺旋齿轮34旋转地驱动输送辊轴27的马达41,盘35 被检查装配到输送辊轴27上,传感器主体37安装在框架21上并检测待检测的盘35的旋转。 纸张输送装置还包括螺旋弹簧40,用于通过在推力方向上偏置来输送辊轴27到框架21的基准端30c。 螺旋弹簧40的偏置力大于螺旋齿轮34的推力。螺旋弹簧40与输送辊轴27同轴设置。输送辊轴27延伸穿过螺旋弹簧40.
