ABSTRACT:
An apparatus for stacking sheet-like articles such as envelopes side by side, i.e., horizontally, in the upright state is disclosed. An article urging lever is disposed in the neighborhood of an article supply path, along which an article to be stacked proceeds toward a stacking position, such that it is rockable between an advanced position, in which the lever is found on and blocks the article supply path, and a retreated position, in which the lever is out of the path. In the advanced position, the lever serves to prevent the stacked articles from blocking the progress of a new article along the supply path into the stacking position and also to engage the rear end portion of an article supplied into the article supply path from one side of the article and thus urges the article's rear end portion crosswise with respect to the longitudinal direction of the path, thereby permitting the next article supplied to the article supply path to freely proceed along the path. The article urged by the article urging lever is brought into engagement at its lower edge with a feed screw member and is further displaced crosswise by the action of the feed screw member. The article entering the article supply path thus can reach a forced feed mechanism, so that its forward end portion is forcibly pulled in and brought to the stacking position by the forced feed mechanism.
