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.
Claims14
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 fixedly 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 backwardly with respect to said at least one second pin-alignment in a direction of insertion of said at least one image recording material,
- wherein said at least one image recording material includes one image recording material, said image recorder selectively executes positioning of a small-size single-mounting image recording material and a large-size single-mounting image recording material with only said pair of first pins of said plurality of positioning pins brought into contact with a leading edge of said at least one image recording material, and
- when said at least one image recording material includes two image recording materials, said image recorder executes positioning of said two image recording materials such that said two image recording materials are both mounted on said surface.

- 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 includes:
- 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 substantially in parallel to the axis of said recording drum, wherein
- said at least one second pin-alignment is offset forwardly by a predetermined offset amount with respect to said first pin-alignment in a direction of insertion of said at least one image recording material,
- when said at least one image recording material includes one image recording material, said image recorder selectively executes positioning of said at least one image recording material with said pair of first pins brought into contact with a leading edge of said at least one image recording material, and
- when said at least one image recording material includes two image recording materials, said image recorder previously forms a notch corresponding to said predetermined offset amount in a position where said two image recording materials and said pair of first pins are in contact, and executes positioning of said two image recording materials such that said two image recording materials are both mounted on said surface.
