ABSTRACT:
An apparatus for mounting a daisy wheel on a shaft driven by a motor in a daisy wheel printer comprises a driving head carried by the driven shaft at its free end, while the daisy wheel is provided with a coupling member. This coupling member is adapted to be coupled in a rotation fixed manner with and to be removed from the driving head by moving the daisy wheel in a substantial radial direction. A locking means is movable between a release position in which the daisy wheel is movable in a substantial radial direction with respect to the driving head and a working position in which the daisy wheel is locked on the driving head.
A daisy wheel to be used in a printer with such an apparatus, comprises a central portion and a number of radially extending spokes carrying at their ends a letter, figure or a similar character. Two ribs are formed in V-shape on the one side of the daisy wheel.
