Abstract

Selon la présente invention, comme décrit ci-dessus, le type et le nombre de tranches requis peuvent être déchargés à partir de multiples cassettes tandis que les cassettes dans lesquelles les tranches sont stockées sont déplacées le long d'une trajectoire fixe, et les cassettes, qui sont déplacées dans la direction horizontale dans l'état antérieur, sont tournées dans une direction longitudinale de telle sorte que des effets maximaux peuvent être obtenus avec un espace minimal.
