A tattoo device includes a rotary motor having a built-in motion conversion coupling. The device comprises a frame and an actuator for actuating a needle-driving shaft. The actuator includes an electric motor comprising a stator mounted to the frame, first and second bearings mounted to the frame, and a rotor comprising a rotor shaft rotatably supported at the first and second bearings, and a motion conversion member for converting rotation motion of the rotor to translation motion for reciprocally actuating the needle-driving shaft. The motion conversion member is positioned between the first and second bearings.
