Abstract: The present invention provides an ink jet recording apparatus in which many components in a carriage-driving system are unitized into a carriage frame. The apparatus comprises a carriage loaded with a recording head for discharging ink from a plurality of nozzles, a carriage-driving device for driving the carriage, a bendable electric wire, and a carriage frame. The electric wire is bent from an apparatus body and mounted to the recording head and passes a printing signal to the recording head. The carriage frame arranges the carriage, the carriage-driving device, the recording head, and the electric wire at predetermined positions to form a unit. The carriage can reciprocate in parallel with the main scan direction along the longitudinal direction of the carriage frame. As a result, the recording head can be easily replaced, and the apparatus can be maintained without complicated work.

Abstract: An ink jet recording apparatus includes a disc tray which is contained in the recording device and on which a DVD disc is to be placed, a select switch for switching between a protruding state and an accommodated state of the disc tray, and a sheet feed tray on which recording sheets are placed and which are disposed substantially parallel to the disc tray, wherein the select switch, the sheet feed tray and the disc tray are operated on the front side of the ink jet recording apparatus. Further, a disc tray is movable in a printing direction and a tray discharge direction. When the disc tray is loaded into or unloaded from the recording device, the disc tray is transported in the tray discharge direction to move to outside an ink jet recording device. In other cases than the above case, the disc tray is accommodated in the ink jet recording device. Thus, the disc tray is transported into two directions.
