摘要： A cassette (7) for a printing ribbon (8) comprises a casing (11) accommodating a supply spool (23) which has a tube (26) on which the printing ribbon 8 is wound. An anti-unrolling element (9) of plastics material comprises two portions (31) and (32) of elongate shape, which are connected by means of an integral elastic hinge (33). The first portion (31) performs a guiding and positioning function and is accommodated by means of a slot (34) within the casing (11). The second portion (32) has a blocking function with regard to the tube (26), and is movable on the outside of the casing (11), by means of the elastic hinge (33) from an inoperative position in which it is aligned with the first portion (31), to an operative position in which it is rotated through 180 o and is substantially in superposed relationship with the first portion (31). The second portion (32) is provided with a hook element (48) which, in its operative position, engages the tube (26) through an opening (53) in the casing (11) for positively blocking the supply spool both during storage and during transportation of the cassette (7), to inhibit unrolling in a simple and reliable manner.

摘要： A cartridge (11) for a typewriter typing ribbon (18) comprises a container (17) for accommodating the typing ribbon (18) which can be of correctable or non-correctable type. A corrector cartridge (12) can be removably fixed on the lower part of the container (17) by engagement means (31). The corrector cartridge (12) accommodates a correction ribbon (27) which can be of the lift-off type suitable for the typing ribbon of correctable type, or of the cover-up correction type which is suitable for the typing ribbon of non-correctable type. Coupling means (32) on the cartridge (11) and the corrector cartridge (12) permit the engagement means (31) removably to fix the corrector cartridge (12) to the container (17) only when the cartridge (11) houses the typing ribbon of correctable type and the corrector cartridge (12) houses the correction ribbon of lift-off type or alternatively when the typing ribbon is of non-correctable type and the correction ribbon is of the cover-up type. In the event of a different choice, the coupling means (32) prevent the engagement means (31) from operating when the ribbons are not compatible with each other. Fixing means (88, 92) removably fix the container (17) to a support of the typewriter either by itself or with the corrector cartridge (12) attached and the fixing means do not co-operate and interfere with the engagement means (31) and the coupling means (32).

摘要翻译： 用于打字机打字色带（18）的盒（11）包括容纳可以是可校正或不可校正类型的打字色带（18）的容器（17）。 校正器盒（12）可以通过接合装置（31）可拆卸地固定在容器（17）的下部。 校正盒（12）容纳校正色带（27），该校正色带（27）可以是适合于可校正类型的打字色带或适用于不可校正打字色带的遮盖校正类型的剥离型 类型。 只有当墨盒（11）容纳打字时，墨盒（11）和校正墨盒（12）上的耦合装置（32）才能将可拆卸地将修正器卡盒（12）固定到容器（17）上， 可修正类型的色带和校正器盒（12）容纳剥离类型的校正带，或者当打字色带是不可校正的类型并且校正色带是遮盖型时。 在不同的选择的情况下，当带彼此不兼容时，联接装置（32）防止接合装置（31）操作。 固定装置（88,92）将容器（17）可拆卸地固定到打字机的支撑件上，或者通过其自身或与安装的校正器盒（12）固定在一起，并且固定装置不协调并干扰接合装置（31） 和耦合装置（32）。
