Abstract
An image recorder of an external drum type includes a feed/discharge unit located above a drum and having an upper tray and a lower tray. The upper tray is inclined so that an edge thereof on the front side of an image recorder body is downward or at a lower level. For placing a plate on the upper tray, the plate is fed over the lower edge of the tray onto the tray. The upper tray has a movable suction pad for raising the plate. The image recorder of the external drum type can easily feed a large-size image recording material or plate over an upper edge of the inclined tray onto the tray.
Claims10
An image recorder having a front surface and a rear surface, comprising:
- an exposure unit for performing an image formation process on an image recording material mounted on an outer surface of a recording drum;
- and
- an image recording material feed unit located above said recording drum for feeding said image recording material to said recording drum,
- said image recording material feed unit including
- a tray having a front edge on the front surface side and a rear edge on the rear surface side and located angularly so that said front edge is below said rear edge,
- a guide member for guiding said image recording material fed from said front surface side to near said front edge of said tray, and
- a raising member for holding said image recording material guided by said guide member to said tray to raise said image recording material until said image recording material is received throughout its length on said tray.
An image recorder, comprising:
- a guide member guiding an image recording material introduced;
- a transport mechanism having an ascent surface above which said guide member is terminated, said transport mechanism being operable to receive said image recording material from said guide member and convey said image recording material along said ascent surface;
- a tray having an ascent slope on which at least a leading part of said image recording material is received from said transport mechanism;
- a reverse controller reversing a convey direction of said transport mechanism whereby a feeding direction of said image recording material is reversed;
- a drum on which said image recording material is fed from said tray and said transport mechanism in response to reversal of said convey direction, said image recording material being wound on said drum;
- and
- an image recording device recording an image on said image recording material wound on said drum.
A method of leading an image recording material onto a drum for image-recording, said method comprising the steps of:
- introducing said image recording material along a guide member;
- leading said image recording material onto an ascent surface of a transport mechanism;
- conveying said image recording material along said ascent surface toward an ascent slope of a tray;
- reversing a feeding direction of said image recording material;
- and
- catching said image recording material on said drum.
