Abstract
A device (1), particularly a facsimile apparatus, has a reversible motor (26), an intermediate transmission gear (29) which is drivable by the motor (26), and three drive wheels (44, 48, 51) which are drivable with the aid of the intermediate transmission gear (29). The intermediate transmission gear (29) includes a basic member (30) which is drivable by the motor (26), a control member (36), and a drive member (37). A first unidirectional coupling of the basic member (30) and the control member (36), and a second unidirectional coupling of the basic member (30) and the drive member (37) are constructed to transmit power in opposite directions of rotation (31, 32). The control member (36) is adapted to selectively establish a drive transmission between the motor (26) and at least one drive wheel (44, 48, 51), and the drive member (37) is adapted to drive the drive wheels (44, 48, 51).
