LIQUID INJECTION RECORDING DEVICE

PROBLEM TO BE SOLVED: To facilitate the exchange of recording heads, and to improve accuracy for positioning the recording heads to a recorder body.SOLUTION: The liquid injection recording device comprises a plurality of the recording heads which discharge droplets to a sheet passing through a conveying belt and form images. The plurality of recording heads can be exchanged with respect to the recorder body. The recorder also comprises screws 46 and nuts 47 for integrating the plurality of recording heads while they are overlapped, and a guide rail 50 which is formed at the recorder body and detachably guides the screws 46 and the nuts 47 while the plurality of recording heads are integrated, and a guide rail pair. An interval between the plurality of recording heads and the conveying belt is held by the screws 46 and the nuts 47, the guide rail 50 and the guide rail pair.
