Abstract

A capping device for an ink jet recorder is provided with a support frame of substantially L-shaped cross-section contained in a frame and supporting an ink absorbing member inside thereof, and a throttle plate in contact with the underside of the absorbing member and disposed substantially parallel to the support frame, the capping device being so disposed that the rear end edge of the throttle plate opposite to a recording head is situated vertically below the side edge surface of the recording head. The specification also discloses an ink jet recording apparatus having such capping device. (FIGS. 1 and 6-8). A flow path for directing liquid squeezed from the absorbing member has upper and lower stages, the upper stage having a sufficiently large diameter that a liquid meniscus does not form and the lower stage having a small diameter that permits a meniscus to form. (FIGS. 9 and 10).
