The sheet moves downwards between the inclined frame and the first guide member and then moves between the base and the second guide member. The first guide member is rotatably supported so that the first guide member is raised and the inclined frame is lowered, a first space is formed between the lowered inclined frame and the raised first guide member. The second guide member is rotatably supported so that the second guide member is raised, a space is formed between the base and the second raised guide member.
