Abstract:
An inkjet recording apparatus for discharging ink from a nozzle of a recording head, comprising:a cap for the recording head, which can be brought into and out of contact with a nozzle-forming surface and which covers the nozzle when abutting against the nozzle-forming surface, the cap comprising: an elastically deformable contact section for forming an enclosed space for covering the nozzle by being pressed into contact with the nozzle-forming surface; and a stopper for restricting an amount of deformation of the contact section by being pressed into contact with a position outside of a position where the contact section is pressed into contact with the nozzle-forming surface, so that the contact section is elastically deformable to a predetermined amount; moving means for bringing the cap for the recording head into and out of contact with the recording head; and absorbing means for communicating with the contact section and also for generating a negative pressure in the enclosed space, wherein when the contact section abuts against the nozzle-forming surface of the recording head by the moving means, the stopper does not abut against the nozzle-forming surface, whereas when a negative pressure with at least a predetermined value is generated in the enclosed space by the absorbing means, the stopper abuts against the nozzle-forming surface of the recording head together with the contact section.
