The object of the invention is to provide a printer-plotter capable of achieving cost reduction. To resolve this object, there is provided a printer-plotter comprises a guide rail 40 extending in the lateral direction, first and second heads 50, 60 which are supported by the guide rail 40 and are movable in the lateral direction independently from each other, and a head driving device 80 having a driving carriage 85 which is supported by the guide rail 40 and is movable in the lateral direction between the first head 50 and the second head 60. To conduct a predetermined action relative to a medium M by using the first head 50, the first head 50 is connected to the driving carriage 85 by a first connecting mechanism 110 and the second head 60 is separated from the driving carriage 85. To conduct a predetermined action relative to the medium M by using the second head 60, the second head 60 is connected to the driving carriage 85 by a second connecting mechanism 121 and the first head 50 is separated from the driving carriage 85. |
