Title
(EN) USAGE DETERMINATION OF MULTI-FEED PREVENTION ROLLER
(ZH) 片材进给装置和图像形成装置
Abstract
(EN)
A sheet feeding apparatus includes a sheet stacker to stack at least one sheet; a sheet feed roller disposed at one side of the sheet stacker and to feed a sheet fed from the sheet stacker; a multi-feed prevention roller disposed to face the sheet feed roller and to prevent multi-feed of the sheet fed from the sheet stacker; a magnetic torque limiter disposed coaxially with the multi-feed prevention roller; a hall sensor disposed at one side of the magnetic torque limiter and to detect rotation of the magnetic torque limiter; and a controller configured to rotate the sheet feed roller in a state in which the sheet feed roller and the multi-feed prevention roller are in contact with each other without a sheet and to identify a lifetime of the multi-feed prevention roller by using a signal output from the hall sensor.

(ZH)
一种片材进给装置包括:片材堆叠部,用于堆叠至少一张片材;片材进给辊,设置在所述片材堆叠部的一侧,并且用于进给从所述片材堆叠部进给的片材;多张进给防止辊,设置为面对所述片材进给辊,并且用于防止从所述片材堆叠部进给的片材的多张进给;磁性扭矩限制器,与所述多张进给防止辊同轴地设置;霍尔传感器,设置在所述磁性扭矩限制器的一侧,并且用于检测所述磁性扭矩限制器的旋转;以及控制器,被配置为使所述片材进给辊在所述片材进给辊与所述多张进给防止辊在没有片材的情况下彼此接触的状态下旋转,并通过使用从所述霍尔传感器输出的信号识别所述多张进给防止辊的寿命。
