Inventor: FUKUI TAKASHI
IPC: G03F7/20
Filed: 2001-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce the image recording time by surely positioning photosensitive material wound on a rotary body and rotating the body at a higher speed. SOLUTION: Intermittent through-holes 90 are formed on a rotary drum 54. When front tip and back tip holding devices 62 and 74 are mounted on the drum 54, supporting poles 154 are supported by the inner peripheral surface of the drum 54. Since these are provided and made beforehand suitable for the size of printing plates 12 having a high frequency of utilization, the above is possible to be used for almost all of the plates 12. By making the fixed objects of the devices 62 and 74 to be the through-holes 90, the thickness size of the drum 54 is made smaller compared with the case in which a groove having an approximate T shape is formed and the weight is reduced. Thus, the rotation load of the drum 54 during a rotation is reduced and the rotation of the drum 54 is made more stable and the speed becomes faster.
