RECORDING DEVICE, ACTUATOR AND LIQUID INJECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To simplify the structure of a recording device by taking advantage of characteristics of an actuator.

SOLUTION: This ink-jet type recording device 100 is provided with a carrying part 130 including a carrying drive roller 132 rotated around a shaft orthogonal to a carrying direction and a carrying driven roller 134 pressed against and rotated together with the carrying drive roller 132 and carrying recording paper 170; a recording head 164 discharging ink toward the recording paper 170; and a discharge part 150 including a discharging drive roller 152 rotated around a shaft orthogonal to the carrying direction and a discharging driven roller 154 rotated together with the discharging drive roller 152 and discharging the recording paper 170. The recording device 100 is further provided with a vibrator 300 having a piezoelectric material plate 322 extended/contracted by applying periodically changed voltage to it and a pair of abutment parts 318, 319 one of which drives carrying drive roller 132 and the other of which drives the discharging drive roller 152.
