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.
Apparatus for mounting a daisy wheel with a wheel side in a daisy wheel printer on a shaft driven by a motor, said printer comprising a carriage which supports the motor and the driven shaft wherein said drive shaft carries a driving head with three head sides formed as an equilateral triangle at its free end and the daisy wheel is provided with a coupling member adapted to be coupled in a fixed manner with the driving head and to be removed from said driving head by moving the daisy wheel in a substantially radial direction, wherein a locking means is provided which locking means is movable between a release position in which the daisy wheel is movable in a substantially radial direction with respect to the driving head, and a working position in which the daisy wheel is locked on the driving head, said locking means including two ribs formed in a V-shape on the wheel side, which ribs engage two head sides in the operating position of the daisy wheel.
Daisy wheel to be used in a printer with a shaft driven by a motor, a carriage for supporting the motor and the shaft, a driving head mounted on said shaft and having three head sides formed in an equilateral triangle around said shaft, said daisy wheel comprising a wheel side, a central portion and a number of radially extending spokes carrying at their ends a letter, a figure or a similar character, wherein two ribs are formed in a V-shaped on the wheel side for engaging two head sides when said wheel is placed in an operating position in said printer.
