Abstract
An ink jet printer in which a mechanism for carrying a recording medium and a mechanism for performing maintenance of a recording head are driven by a common driving source miniaturizing the printer. A carrier roller is arranged with both ends carried on side frames of a box whose upper surface has a carrying path for the recording medium. One side frame is arranged to carry a driving-force transmission mechanism for transmitting a driving force of a motor to the carrier roller. A maintenance mechanism having a suction cap, a pump and a cam for driving the pump is arranged externally of a second side frame. A maintenance driving-force transmission mechanism, for transmitting a driving force to the cam, is arranged internally of the second side frame. A transmission gear, meshed with a maintenance gear, is provided at one end of the carrier roller to enable the transmission of the driving force from the carrying driving-force transmission mechanism to the maintenance driving-force transmission mechanism.
