The present invention relates to a post frame for X-ray apparatus and a ceiling type X-ray apparatus. The ink jet recording apparatus further includes a detection unit configured to detect a remaining amount of ink in the ink tank, and a preliminary discharge unit configured to discharge ink from the discharge ports, unrelated to recording, by applying energy to the heating elements for recovering the recording head. The capacitor conductors define a capacitor. The illuminating device has a housing, a lamp on the housing, a battery chamber in the housing to receive battery therein and a second joint portion on the housing. The sleeve is disposed within the axial slot and configured to surround the stator coil.
