Post-processing device

Abstract

Provided is a post-processing device including a first stacking member on which recording materials are stacked, an extension member that is connected to one end side of the first stacking member and that supports the recording material, and a second stacking member on which plural recording materials are stacked as a recording material bundle and which is placed so as to be movable in a direction intersecting a discharge direction of the recording material bundle, wherein the extension member is connected to the first stacking member so as to be non-rotatable in a direction approaching the second stacking member and be rotatable in a direction away from the second stacking member.

1 . A post-processing device comprising:
 a first stacking member on which recording materials are stacked;   an extension member that is connected to one end side of the first stacking member and that supports the recording material; and   a second stacking member on which a plurality of recording materials are stacked as a recording material bundle and which is placed so as to be movable in a direction intersecting a discharge direction of the recording material bundle, wherein   the extension member is connected to the first stacking member and configured to be rotatable in a direction away from the second stacking member when the second stacking member moves towards the first stacking member, and   a rotation receiving portion is configured to hold the extension member erect when the extension member rotates.   
     
     
         2 . The post-processing device according to  claim 1 , further comprising:
 a support shaft that is provided at the first stacking member and to which the extension member is rotatably connected, wherein   the extension member has one end side on which a hole is formed, the hole being inserted into the support shaft,   the support shaft includes a first support shaft portion, at least a portion of which has a cylindrical cross-sectional shape, and a second support shaft portion having a double D-cut cross-sectional shape, and   the hole includes a first connection portion having a recessed portion cross-sectional shape in which the first support shaft portion is inserted, and a snap-fit portion in which the second support shaft portion is inserted.   
     
     
         3 . The post-processing device according to  claim 2 , wherein
 a cut surface of the double D-cut cross-sectional shape of the second support shaft portion is formed in a range greater than or equal to 90 degrees with respect to a rotation direction of the extension member with a state where the extension member is connected to the first stacking member so as to be non-rotatable in a direction approaching the second stacking member as a reference position.
