Abstract
A fixing structure comprises a rotary drum having an outer peripheral surface, around which a printing plate is wound, and an inner peripheral surface portion, the drum including through-slots formed in the outer surface at predetermined intervals in the peripheral direction, each of which communicates the outer surface with the inner surface portion; and a chuck detachably mountable to the drum, for clamping one end of the printing plate onto the drum, the chuck including a support having opposite ends, a clamp plate provided on one support end, and a base section provided on the other support end, wherein when the chuck is mounted on the drum, the base section is inserted and passed through one associated through-slot and then hooked over the inner surface portion.

A fixing structure for detachably fixing a sheet member, comprising:
- a rotor having an outer peripheral surface, around which the sheet member is wound, and an inner peripheral surface portion, the rotor including a plurality of through-slots formed in the outer peripheral surface of the rotor at predetermined intervals in the peripheral direction, with each of the through-slots being elongated in the peripheral direction and communicating the outer peripheral surface with the inner peripheral surface portion;
- and
- a chuck detachably mountable to the rotor, for clamping one end of the sheet member onto the rotor, the chuck including a support having opposite ends, with a clamp plate being disposed at one end of the support and a base section being disposed at the other end of the support, wherein when the chuck is mounted on the rotor, the base section is inserted and passed through one associated through-slot and then hooked over the inner peripheral surface portion.
An apparatus for forming an image on a printing plate, comprising:
- a rotary drum having an outer peripheral surface, around which the printing plate is wound, and an inner peripheral surface portion, the rotary drum including a plurality of through-slots formed in the outer peripheral surface of the rotary drum at predetermined intervals in the peripheral direction, with each of the through-slots being elongated in the peripheral direction and communicating the outer peripheral surface with the inner peripheral surface portion;
- a chuck detachably mountable to the rotary drum, for clamping one end of the printing plate onto the rotary drum, the chuck including a support having opposite ends, with a clamp plate being disposed at one end of the support and a base section being disposed at the other end of the support, wherein when the chuck is mounted on the rotary drum, the base section is inserted and passed through one associated through-slot and then hooked over the inner peripheral surface portion;
- and
- a recording head disposed for recording an image on the printing plate wound on the rotary drum.
