摘要： A variable speed unit is driven by a drive unit to make a tooth-missing large gear of a sheet feed tooth-missing stage gear mesh with a small gear of an input stage gear rotating at a constant speed, to then rotate a rotating shaft of the feeding roller and a cam at a first speed to lift an intermediate plate. If a sheet stacked on the intermediate plate is pressed against the feeding roller, the variable speed unit makes a large gear of the input stage gear and a tooth-missing small gear of the sheet feed tooth-missing stage gear mesh with each other, so that the rotating shaft of the feeding roller is rotated at a second speed faster than the first speed to rotate the feeding roller at a fast speed.

摘要翻译： 变速单元由驱动单元驱动，使得输入级齿轮的小齿轮以一定速度旋转的片材进给缺齿级齿轮啮合齿的缺齿大齿轮，然后旋转 进给辊和第一速度的凸轮以提升中间板。 如果堆叠在中间板上的片材被压靠在馈送辊上，则可变速单元使输入级齿轮的大齿轮和供纸缺齿级齿轮的缺齿小齿轮彼此啮合，因此 进给辊的旋转轴以比第一速度快的第二速度旋转，以快速旋转进给辊。
