のである。 In the figure, 1 indicates the bottom plate 2 and the stopper 3 at the tip.
This stacker 1 has a paper refeed roller 4 that can move up and down at the upper front part of the stacker 1. Further, a roller 5 for feeding the paper onto the bottom plate 2 is provided above the rear end of the stacker 1. A paper sensor 6 is provided adjacent to the feed roller 5. This paper sensor 6 detects the paper 7 entering the stacker 1.
