PURPOSE:To make the device compact and to give a margin to the layout on the outer periphery of a rotary drum by arranging a writing device and a support device in the rotary drum. CONSTITUTION:A thermal head 2 as the writing device and a platen roller 3 are arranged in the rotary drum 1 across a photosensitive sheet A on the side of one driving roller 10. The shaft of the platen roller 3 is supported on the end plate of the drum 1 so as to rotate and move at right angles to the axis, the platen roller 3 moves toward the thermal head 2 arranged fixedly on the rotary drum shaft to contact the thermal head, and the shaft of the roller 3 is coupled with a driving transmission member to rotate in the same direction which the drum 1. Those writing devices 2 and 3 and support device are installed in the rotary drum 1. Consequently, the device can be designed with the margin of the layout and made compact. |
