Abstract
A printing disc (1) is applied by a leaf spring (9) against a plate (6), provided with projections (14), of a support (2). These projections (14) lock the printing disc (1) in a predetermined position in the support (2). This support (2) is provided to be introduced in a typewriter transversely to the selecting shaft (15) between the driving plate (18) and the card press (16) the two folded over borders (23) of which form lateral guides. Two slots (26) of these borders (23) form abutments for bosses (25) of the support (2). The support (2) has an opening (8) opposite the hub (3), the engagement of the hub (3) of the disc (1) on the driving plate (18) is effected by pivoting the support (2) in the direction of the selecting shaft (15). The driving plate (18) passes through the opening (8) and holds the printing disc (1) spaced apart from the projections (14). This device is light and permits the mounting of the disc (1) without having to displace the selecting shaft (15).
