摘要:
The invention concerns a device in printers of the kind wherein an ink ribbon (5) is arranged to be reeled off an unwinding roller (4) and to be wound onto a take-up roller (6) after having passed through a printing unit (7). In order to compensate for any skewing forces occuring in the ribbon (5), the unwinding roller (4) and/or the take-up roller (6) is/are mounted on a rotatable shaft (8) which is provided with a pivot mechanism (9, 11, 12; 21; 22, 24), allowing correcting guide movements of said ribbon (5).

A printer comprising a printing head (4); a cartridge holder (15) for releasably holding a multi-colour ink ribbon cartridge (18) containing ink ribbon material (17) different parts (17 a , 17 b , 17 c , 17 d ) of which are differently coloured; and drive means (19) for adjusting, by way of drive transmission means (13,14), the relative positions of the printing head (4) and of a multi-colour ink ribbon cartridge (18) held in the cartridge holder (15) to enable a selected said part (17 a , 17 b , 17 c , 17 d ) of the ink ribbon material (17) and the printing head (4) to be brought into alignment for printing characterised in that the cartridge holder (15) is also adapted releasably to hold a cartridge containing a monochromatic ink ribbon, the drive means (19) being freely removable from the printer, the arrangement being such that, when the drive means (19) is removed from the printer, only monochromatic printing can be effected and, when the drive means (19) is installed on the printer, either multi-coloured or monochromatic printing can be effected as desired.

The present invention provides a cassette (2) for a printer unit (1) comprising:
an endless ribbon; means for transporting the ribbon; and means (7) causing the ribbon to move reciprocally comparatively slowly in a direction substantially transversely of the direction of movement of the ribbon.
The moving means preferably comprise a (gradually) camming track (7), the driving (4,5,6) of which is coupled to the transporting means for the ribbon.

Cartouche à ruban encreur pour une imprimante comprenant une bobine d'emmagasinage pour un ruban encreur, une bobine enrouleuse pour le ruban encreur, et des roues d'entraînement pour faire avancer le ruban encreur et le tranférer de la bobine d'emmagasinage à la bobine enrouleuse afin d'imprimer sur le ruban, et une poulie montée sur une came pour déplacer transversalement le ruban pendant son avance longitudinale et décaler ainsi la surface du ruban utilisée pendant l'impression.
摘要:
An ink ribbon cassette (10) is pivotally mounted to a printer (50). An ink ribbon (14) is accommodated in the ink ribbon cassette and is caused to travel by a ribbon feed roller (20) driven by a drive shaft provided in the printer. Printing operation is carried out at the cassette end arm portion (18) by a printing head (54), while the cassette end arm portion is reciprocatingly moved in the widthwise direction of the ink ribbon (14) relative to the fixed printing head (54) by an actuating mechanism (26,28,30,32,34) so that a printing region of the ink ribbon is diffused and becomes wider than a printing width of the printing head. The actuating mechanism includes a small gear (26) integral with the ribbon feed roller, a cam (30) driven by the small gear, and a lever (34) engaging with the cam.
