BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments will now be described, by way of example only, with reference to the accompanying drawings which are meant to be exemplary, not limiting, and wherein like elements are numbered alike in several Figures, in which:
FIG. 1 shows an example of a rough configuration of a paper sheet conveyance apparatus embodied in the present invention;
FIG. 2(
a) and FIG. 2(b) show explanatory schematic diagrams for explaining a separating operation of overlapping paper sheets, when a thickness detecting sensor detects an overlapping conveyance at a portion being apart from a leading edge of a paper sheet by a distance smaller than 20 mm;
FIG. 3(
a) and FIG. 3(b) show explanatory schematic diagrams for explaining a separating operation of overlapping paper sheets, when a thickness detecting sensor detects an overlapping conveyance at a portion being apart from a leading edge of a paper sheet by a distance equal to or greater than 20 mm;
FIG. 4(
a), FIG. 4(b) and FIG. 4(c) show flowcharts of processing procedures of a first suction device and a second suction device, both of which are controlled by a control section embodied in the present invention;
FIG. 5 shows a subroutine flowchart for commencing an operation of a first suction device in which an amount of wind flow is controlled on the basis of a basis weight of a paper sheet;
FIG. 6 shows a schematic diagram of a paper sheet conveyance configuration in which an overlap paper sheet, separated from a conveyance paper sheet, is conveyed into a reuse conveyance path through an overlapping conveyance path; and
FIG. 7 shows a schematic diagram of a rough configuration of a conventional separating conveyance apparatus.
