<p>PURPOSE:To guide a sheet reversing from an inversive path certainly to a reversing route by furnishing a counter-feed checking member, which is rotationally energized to the position of guiding the reversing sheet to the reversing route, on the guide wall side of a curving route continued to the guide wall on the intrusive path side of the inversive path. CONSTITUTION:A sheet guide path according to the present invention includes a sheet intrusive path 1, inversive path 2, and exhaust path 3, wherein the intrusive path 1 leads to the inversive path 2 via route 4 while the inversive path 2 leads to the exhaust path 3 via a reversing route 5, and the inversive path 2 is fitted with regular/reverse feed rollers 8. At the intersection of these three paths 1-3 a rotary guide member 10 is furnished which is changed over from the position, as opening a straight route 9 tying the intrusive path 1 to the exhaust path 3 and blocking the curving route 4, to the position as blocking the straight route 9 and opening the curving and reversing routes 4, 5, or vice versa. On the guide wall side of the curving route 4 continued to the guide wall on the intrusive path 1 side of the inversive path 2, a counter-feed checking member 12 is furnished, which rotates round a shaft 12a when pushed by the sheet advancing from the intrusive path 1 to the inversive path 2.</p> |
