PURPOSE:To reduce a width dimension by constituting the title apparatus so that either one of a carriage and an ink ribbon cassette or a part of both of them protrudes to the outside of an exterior case from the opening part provided to the side surface of the exterior case. CONSTITUTION:A carriage 6 loaded with an ink ribbon cassette 5 is guided by a guide shaft 10 and driven by a belt 9 to reciprocally move. The lid 12 provided to the right-hand surface of an exterior case 11 is mounted so as to be revolvable around a hinge shaft 13 and energized in a counterclockwise direction by a spring device to cover an opening part 11a. When the carriage 6 is moved in the right direction, the right end part 6a of the carriage 6 is brought into contact with the lid 12 beforehand and, when the carriage 6 is further moved to the right, the lid 12 is pushed by the carriage 6 to be revolved around the hinge shaft 13 in the clockwise direction against the force of the spring device and opened automatically to allow the carriage 6 to protrude to the outside of the exterior case 11. By this method, the lateral width of this apparatus can be reduced by the protruding dimension of the carriage to the outside of the exterior case at the terminal of a stroke.
