Abstract
An image recorder includes a punch unit for punching a hole in a plate. The punch unit has six punchers disposed movably. Punches of the punchers can punch holes of different configurations. A punch of a required configuration moves to a required location toward a plate prepared on an upper tray of a feed/discharge unit. After a hole is punched in the plate by this punch, the plate is fed to a drum. This allows changes in the location of a punched hole in the plate without the need to simply increase the number of punchers when the range of plate sizes mountable on the drum is expanded. If competition in punch standards occurs, the image recorder allows a required puncher to be situated in a desired location.

1-6. (canceled)
An image recorder comprising:
- a cylindrical recording drum for mounting at least one image recording material on a surface thereof;
- a rotation mechanism for rotating said recording drum in a predetermined direction of rotation;
- a first recording head for recording an image on said at least one image recording material mounted on said recording drum;
- and
- a plurality of positioning pins disposed to protrude through said surface for positioning said at least one image recording material with respect to said recording drum, wherein said plurality of positioning pins include:
- a first pin-alignment having a pair of first pins, disposed almost in parallel to the axis of said recording drum;
- and
- at least one second pin-alignment each having at least one pair of second pins, disposed almost in parallel to the axis of said recording drum, wherein said first pin-alignment is offset with respect to said at least one second pin-alignment in said predetermined direction of rotation of said recording drum.
An image recorder comprising;
- a cylindrical recording drum for selectively mounting on a surface thereof one of a single-mounting image recording material and two double-mounting image recording materials;
- a rotation mechanism for rotating said recording drum in a predetermined direction of rotation;
- a first recording head for recording an image on an image recording material mounted on said recording drum;
- and
- a plurality of positioning pins disposed to protrude through said surface for positioning said image recording material mounted on said recording drum with respect to said recording drum, wherein
- said plurality of positioning pins include:
- a first pin-alignment having a pair of first pins, disposed almost in parallel to the axis of said recording drum, said pair of first pins being symmetric with respect to the centerline of said recording drum;
- and
- at least one second pin-alignment having at least one pair of second pins, disposed almost in parallel to the axis of said recording drum, said at least one pair of second pins being symmetric with respect to the centerline of said recording drum,
- wherein
- said image recorder selectively executes first plate handling for positioning said single-mounting image recording material on said surface with an edge thereof brought into contact with said pair of first pins and second plate handling for positioning said two double-mounting image recording materials on said surface at the same time with edges thereof respectively brought into contact with a first pin member selected from said pair of first pins and a second pin member selected from said at least one pair of second pins.
