Abstract
A printer for recording information on one of opposite surfaces of a recording medium, including a recording head displaceable along the one surface of the recording medium, for recording the information on the one surface, a platen device for defining a platen surface which is opposed to the recording head, a vibration device for applying vibration to the platen means and thereby vibrating the platen surface, and an actuating device for, when the recording head is displaced along the one surface of the recording medium, displacing the platen device along the other of the opposite surfaces of the recording medium in a same direction as a direction of the displacement of the recording head and in synchronism with the displacement of the recording head, so that the platen surface continues to be opposed to the recording head. The printer may further include a preventing device for preventing the platen surface from vibrating in a direction different from the vibration direction intersecting an operative surface of the recording head, or a deciding device for deciding whether to operate the vibration device to apply vibration to the platen device. The platen device may include at least one protruding portion protruding from the platen surface toward the recording head.
