Abstract
This specification discloses a capping device having a cap for capping orifices for discharging liquid, and a moving structure for moving the cap, wherein a plurality of engaging members each have an engaging portion adapted to be engaged with a protrusion during the capping, and a releasing structure for moving at least one of the engaging members and releasing the capping. The specification also discloses a liquid injection recording apparatus provided with such capping device and a pump device for generating a pressure utilized to such the liquid from the orifices through the cap, a protrusion being provided in operative association with the movement of a member for effecting the pumping operation of the pump device.
Claims16
A capping device comprising:
- a cap movable between an open position spaced from a head of a liquid injection recording apparatus and a capping position in which said cap is moved toward the head for capping orifices in the head for discharging liquid,
- moving means for cooperating with said cap and with pump means for discharging liquid through the orifices, said moving means being movable between a plurality of positions to move said cap between the open and capping positions thereof and to operate the pump means
- first and second engaging members, each having an engaging portion adapted to be engaged with said moving means to restrict movement thereof, wherein moving said moving means to one of the positions thereof disengages said moving means and said second engaging member and
- releasing means for moving at least said first engaging member to disengage said moving means and said first engaging member.
A liquid injection recording apparatus comprising:
- head means defining orifices for discharging liquid,
- a capping device having a cap movable between an open position spaced from said head means and a capping position in which said cap is moved toward said head means for capping said orifices for discharging liquid,
- moving means movable between a plurality of positions to move said cap between the open and capping positions thereof,
- pump means for generating a pressure for sucking the liquid from said orifices through said cap, said pump means having an operating member for effecting the pumping operation of said pump means,
- a protrusion on said moving means for cooperating with said operating member when said moving means is in one of the positions thereof,
- first and second engaging members, each having an engaging portion adapted to be engaged with said moving means to restrict movement thereof, wherein moving said moving means to one of the positions thereof disengages said moving means and said second engaging member, and
- releasing means for moving at least said first engaging member to disengage said moving means and said first engaging member.
