摘要： A sheet conveying apparatus includes a cover unit opened and closed with respect to an apparatus body and a guide unit including first and second movable guides respectively movable with respect to the apparatus body. A first conveyance path is formed between the first guide portion and the first movable guide, and a second conveyance path is formed between the second guide portion and the second movable guide. The guide unit is provided with a linking mechanism including an intermediate member for linking the first and second movable guides. The linking mechanism coordinates movements of the first and second movable guides such that the first and second movable guides are respectively moved away from the first and second guide portions along with an opening movement of the cover unit with respect to the apparatus body.
