| 1. A paper stacking apparatus stacking fed papers, comprising:
a paper inlet to which said fed paper enters;
a stacking and accommodating portion stacking the papers entering from said inlet;
a movable push plate installed within said stacking and accommodating portion; and
a control portion controlling a position of said push plate,
wherein said stacking and accommodating portion is sloped in such a manner as to be lower in accordance with being away from
said paper inlet,
wherein said stacking and accommodating portion is provided with a leading end detecting means for detecting a position of
a leading end surface of the papers stacked in said stacking and accommodating portion by detecting position of said stack
guide,
wherein the paper stacking apparatus further comprises a memory means for storing a stack number count information corresponding
to the number of the papers accommodated and stacked in said stacking and accommodating portion, and a thickness information
per one of said papers,
wherein said control portion detects a stack width of the stacked papers on the basis of the count information and the thickness
information per one paper stored in said memory means,
wherein said control portion calculates a stack width of the papers stacking in said stacking and accommodating portion, on
the basis of a product of the count information and the thickness information per one paper stored in said memory means, and
wherein said control portion calculates a moving distance of said push plate and executes a control of moving said push plate
by subtracting said stack width from the accommodation width of said stacking and accommodating portion.
