An ink-jet printing apparatus permits sequential ejection of printed papers without causing stain by non-dried ink, improves printing quality and permits down-sizing of the overall apparatus by simplifying a construction of a paper ejecting mechanism. An ink-jet printing apparatus includes a paper ejecting roller rotatable in a first direction for ejecting said printing medium and a second direction opposite to said first direction and an arm member arranged between said paper ejecting roller and said ejected paper stacker and movable between a first position projecting above said ejected paper stacker for supporting said printing medium from a lower side thereof, and a second position retracted from the position above said ejected paper stacker and permitting falling down of said printing medium. The ink-jet printing apparatus further includes motion force transmitting means for transmitting rotation of said paper ejecting roller in said first direction.

A cylindrical pump device comprises a cylindrical housing and a cylindrical rotational member disposed in the cylindrical housing for rotation around the axis of the cylindrical housing. The cylindrical rotational member has a solid cylindrical wall, a central hub and a plurality of flexible blades extending between the central hub and the solid cylindrical wall for defining a plurality of liquid chambers therebetween. The cylindrical housing supports a shaft apart from the central axis of the cylindrical housing. During rotation of he rotational member, the chambers far from the central axis first increases its volume to introduce liquid ink therein and then decreases its volume to discharge the liquid ink from the chamber. Inlet valve or outlet valve for the pump are not necessary to reduce the parts and fabrication cost of a pump system.
