装置。(1) Press the top surface of the stack of paper stacks placed on the paper table against the paper feed means at a predetermined paper feed position to feed paper sequentially from the top, and as the number of sheets decreases, the east top surface of the paper descends and feeds. The first detection means provided at the paper feeding position detects that the paper position exceeds the lower limit of the permissible range, raises the paper table, and feeds the paper by constantly maintaining the east upper surface position at a predetermined paper feeding position. In a paper feeding device that performs paper replenishment and maintenance by lowering the paper table, the second position is located below the paper feeding position and provides a space for easily replenishing at least the smallest unit of paper bundle that is normally replenished. has a second detection means for detecting that there is an upper surface of the paper stack on the paper stack, and when the paper table is raised, the paper table is raised to a position where the first detection means detects the east upper surface of the paper stack. , control means for controlling the paper table to be lowered to a position where the second detection means detects the east upper surface of the paper sheet or the upper surface of the paper table when there is no paper when the condition is such that the paper table is lowered. Paper feeding device featuring Kokichi.
