項に記載のシート搬送装置。[Scope of claims for utility model registration] (1) Carrying in single-sided paper from one end,
In a sheet conveyance device having an intermediate tray that carries out the paper from the same end for re-feeding, a feed roller that is controlled in forward and reverse directions, sandwiching a path for carrying paper into the intermediate tray and carrying out paper from the tray; A separate roller is provided which is supported on a shaft via a one-way clutch, presses against the feed roller, and rotates as a result of the feed roller only in the direction in which paper is carried in, and which sets the intermediate tray in a state in which paper can be received and in which paper is sent out. When transporting paper to the intermediate tray, the intermediate tray is set to a state capable of receiving paper, and the feed roller is rotated in the paper transport direction to transport the paper from the intermediate tray. 1. A sheet conveying device characterized in that the intermediate tray is set in a state in which paper can be fed out, and the feed roller is controlled so as to rotate in a paper feeding direction. (2) A paper edge detection means is provided in the paper carry-out/carry-in path near the pair of rollers, and this detects the trailing edge of the paper carried into the intermediate tray, and changes the state at the time of paper carry-in to the state at the time of carry-out. Claim 1 of utility model registration characterized by switching
The sheet conveyance device described in section.
