Abstract
When a roll paper unit 200 is incorporated into an image formation apparatus, a second outlet guide member 92 is turned around a pivot 92a 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 92b of this second outlet guide member 92 pressing down a front end portion 80c of a guide member 80 to cause the guide member 80 to be turned around a central shaft 80d 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 72 being transferred in the paper feed direction. When the roll paper unit 200 is drawn out, the second outlet guide member 92 and the guide member 80 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 72 being transferred in the paper discharge direction.
