Its structure is based on a support base (1) which is considerably flat, inside which an axial neck (2) is provided which is meant to house the enveloping support (3) for the electric motor (4) which drives the drum, whose drive shaft (10) is connected to a ring (11) provided with a perimetral ring (17) to which in turn is connected the images-bearer continuous band (16), and whose other mouth, overhanging, is stiffened by a second ring (20), which moves in a channel (7) of the support base (1). Support (3) of the electric motor (4) can be adjusted in its position within the axial neck (2) so that ring (11) can be set at different distances from the support base (1) in order to adapt the unit for continuous images-bearer bands (16) of different widths, with the drive unit housed within the drum itself formed by axial neck (2), from which support base (1) only projects slightly, with a minimum volume occupied by the unit. <IMAGE> |
