Abstract

L'invention concerne une cassette ayant une structure à double couche qui réduit la résistance de transport lorsqu'un milieu est abaissé d'une couche supérieure à une couche inférieure, et qui permet une miniaturisation tout en réalisant un transport sans à-coups. Un logement constituant une cassette (10) comprend un boîtier de ruban (21) et un boîtier de bande (20). Le boîtier de bande (20) est pourvu d'un rouleau de bande d'impression (26) sur lequel une bande d'impression (22) est enroulée et d'une nervure de guidage (54). La nervure de guidage (54) a une partie d'inclinaison (54i) qui est inclinée de façon à augmenter une distance du rouleau de bande d'impression (26) vers le boîtier de ruban (21) à partir du boîtier de bande (20). La bande d'impression (22) tirée du rouleau de bande d'impression (26) est enroulée autour de la partie d'inclinaison (54i) de la nervure de guidage (54), moyennant quoi la bande d'impression (22) peut être inclinée le long de la partie d'inclinaison (54i) et une direction de transport de la bande d'impression (22) peut être inclinée vers le boîtier de ruban (21).
