Abstract
On a slider which is pressed by a carriage to follow the movement the carriage while moving up and down on a base in accordance with the movement of the carriage, a cap is provided swingably through a support frame urged against a recording head by a spring or the like so that only one of its corners projects out at the time of non-capping. The cap moving up in accordance with the movement of the carriage, first, comes into contact with a nozzle plate of the recording head, and then expands the contact region gradually until it contacts with the whole of the nozzle plate. Therefore, pressure is concentrated in the contact free region partially so that the cap becomes familiar to the nozzle plate from its one corner and expands the contact region to make sealing finally.
