摘要： A recording drum has a clamp groove extending in its circumferential direction formed on its outer peripheral surface. A plurality of front end clamps are attached to the outer peripheral surface of the recording drum. Rear end clamps are attached so as to be movable and so as to be fixable along the clamp groove on the outer peripheral surface of the recording drum. A recording head is disposed ahead of the recording drum, and a clamp driving device is disposed behind the recording drum. The clamp driving device comprises a first driving device for fixing the front end clamps and fixing and releasing the rear end clamps and a second driving device for releasing the front end clamps. The front end clamps and the rear end clamps reliably fix a front end and a rear end of a plate to the outer peripheral surface of the recording drum by a reaction force produced by a spring and a centrifugal force produced by the rotation of the recording drum.
