When a roll paper unit is incorporated into an image formation apparatus, a second outlet guide member is turned around a pivot in the direction of an arrow G, i.e., moved from a position of solid lines to a position of two-dot chain lines, a rear end portion of this second outlet guide member pressing down a front end portion of a guide member to cause the guide member to be turned around a central shaft in the direction of an arrow H, i.e., moved from a position of solid lines to a position of two-dot chain line. Consequently, a path extending in the direction of an arrow C is closed, while a path extending in the direction of an arrow F is opened, the roll paper being transferred in the paper feed direction. When the roll paper unit is drawn out, the second outlet guide member and the guide member are turned in the directions opposite to those mentioned above. Consequently, the path extending in the direction of the arrow F is closed, while the path extending in the direction of the arrow C is opened, the roll paper being transferred in the paper discharge direction.

Roll paper unit having paper path switching member and image forming apparatus employing the same

An image is formed on roll paper,while a loop,of roll paper is formed between cutter,and roll paper feed rollers,is formed. At a timing when roll paper feed rollers,stop, an upstream portion of loop,in the paper feed direction is cut. A nipping member upstream of the cutter in the paper feed direction is provided to nip the front end of the roll paper. Further, a movable guide for the roll paper guides the paper to form a loop in a direction to correct curling of the roll paper. Thus an image formation apparatus is provided which is easy to handle and enables formation of an image on a recording paper having a large feed paper direction length, despite its small size.
