ABSTRACT:
A carriage device includes a circuit substrate having a conductive connection portion, a connector having a plurality of contact arms, a connector holder in which the circuit substrate and the connector are installed, and a carriage in which a recording head unit is built and an ink cartridge having a conductive connection portion is housed and to which the connector holder is attached with both ends of the connector holder held, wherein contact terminals of the plurality of contact arms of the connector elastically contact the conductive connection portion of the circuit substrate and the conductive connection portion of the ink cartridge which are respectively disposed on both sides of the connector so as to electrically conduct between the circuit substrate and the ink cartridge, wherein a back side support member contacting the circuit substrate for regulating deformation of a face of the circuit substrate on the basis of the elastic contact is provided in the carriage, and wherein a deformation preventing support member is formed on a side opposite a side, on which the circuit substrate is installed, of the connector holder and the deformation preventing support member is configured to be able to contact a supported portion formed inside of the carriage.
