リンタ。 A motor that generates power is connected to a frame, a gear train that transmits the motor power, a type wheel shaft that is reciprocated by the gears, and a pulse generator that is fixed to the type wheel shaft and generates timing pulses as it rotates. a type wheel spindle stopper that is fixed to the type wheel spindle and positions the type wheel spindle; a type wheel that engages with the type wheel spindle and has a plurality of type characters on its outer periphery; and a type wheel that selects desired type on the type wheel. In a small printer whose main components include a selection unit that presses the type wheel by receiving motor power from the gear, and a printing unit that presses the type wheel by receiving motor power from the gear, a bouncing phenomenon is prevented when the type wheel spindle returns to a standby position and rotates. A small printer characterized in that the type wheel spindle stopper is provided with a buffer mechanism.
