摘要： A sheet feeding apparatus (110) includes a sheet stacker (111), an air blower (112), a suction feeder (113), a lifting mechanism (115), an elevation detection sensor (116), an elevation detection sensor (116), a feed detection sensor (117), and a controller (150). The air blower (112) blows air to float an uppermost sheet of sheets stacked on the sheet stacker. The controller drives the lifting mechanism such that the sheet stacker is lifted by an elevation amount determined based on a sheet thickness (t) of the sheets stacked on the sheet stacker, each time a sheet is detected when a number of sheets detected is smaller than a threshold number of sheets, and stops lifting of the sheet stacker until a sheet is not detected when the number of sheets reaches the threshold number of sheets, while repeatedly feeding the uppermost sheet and counting the number of sheets.

摘要： A medium processing apparatus (3) includes a liquid applier (31), a post-processing device (32), a liquid storage unit (44, 47), a mover (35), and a liquid supplier (45, 46). The liquid applier (31) applies liquid to at least one medium (P). The post-processing device (32) performs a given process on a bundle of media (Pb). The liquid storage unit (44, 47) stores the liquid to be supplied to the liquid applier (31). The mover (35) causes the liquid applier (31) to move in a reciprocating direction. The liquid supplier (45, 46) supplies the liquid from the liquid storage unit (44, 47) to the liquid applier (31) and includes an extensible member (453) having an elastic cylindrical part on at least a part of the liquid supplier (45, 46). The extensible member (453) extends in the reciprocating direction of the mover (35).

摘要： A medium processing apparatus (3) includes a liquid applier (31) and a post-processing device (32). The liquid applier (31) includes a liquid application member (44) including a foam containable a liquid to apply the liquid to a liquid application region (B1, 810) in a part of at least one medium (P) of a bundle of media (Pb). The post-processing device (32) performs a given process on a post-processing region (810, 820) in the part of at least one medium (P) having the liquid application region (B1, 810) on which the liquid is applied by the liquid applier (31). The liquid applier (31) applies the liquid to the liquid application region (B1, 820) overlapped with at least a part of the post-processing region (810, 820).
