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.
