Abstract
A dot unit includes an opening formed in a housing and a protruding member disposed in the opening. The protruding member is rotatably supported by a support shaft. The protruding member is rotated by a polymer actuator in a direction that follows a reading direction in which a unit of information is read, and the protruding member is stabilized in a protruding position by contacting a restricting portion. When a finger is moved in the reading direction and contacts the protruding member, the protruding member is likely to be stabilized in the protruding position.
