Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
A printing device comprising a row of printing elements each carrying a plurality of printing characters, a plurality of pressure members for pressing a print medium against the printing elements, and so arranged that each pressure member presses said medium against at least one and not more than three of said pRinting elements, carrier members carrying said pressure members, each carrier member being associated with at least one and not more than three printing elements, resilient means arranged so as to urge said pressure members independently of each other towards the printing elements, stop means limiting the movement of the carrier members towards the printing elements, a plurality of first movable support members on which the carrier members are mounted, a plurality of second movable support members (18) on which the first support members are respectively mounted, first cam means (32) for moving the second support members and thereby also the first support members to bring the pressure members to the said printing surfaces, whereupon the first support members are actuated by second cam means (21) to move the pressure members over the printing characters.
Claim 2
Dependent Claim
185 words
A printing device comprising a row of printing elements each carrying a plurality of printing characters, a plurality of pressure members for pressing a print medium against the printing elements, and so arranged that each pressure member presses said medium against at least one and not more than three of said pRinting elements, carrier members carrying said pressure members, each carrier member being associated with at least one and not more than three printing elements, resilient means arranged so as to urge said pressure members independently of each other towards the printing elements, stop means limiting the movement of the carrier members towards the printing elements, a plurality of first movable support members on which the carrier members are mounted, a plurality of second movable support members (18) on which the first support members are respectively mounted, first cam means (32) for moving the second support members and thereby also the first support members to bring the pressure members to the said printing surfaces, whereupon the first support members are actuated by second cam means (21) to move the pressure members over the printing characters.
Claim 3
Dependent Claim
63 words
A printing device as claimed in claim 1 having an axle on which the carrier members are pivoted, said axle being carried by the first support members, springs which urge the carrier members towards the printing characters, pivots on the second support members which pivots carry the first support members, and spring means which urge the first support members against their cam means.
Claim 4
Dependent Claim
107 words
A printing device as claimed in claim 1 having an axle on which the carrier members are pivoted, said axle being carried by the first support members, springs which urge the carrier members towards the printing characters, pivots on the second support members which pivots carry the first support members, and spring means which urge the first support members against their cam means and wherein the device is so constructed that the axis of the pivot of the first support members on the second support members is moved approximately into coincidence with the axis of the printing elements before the pressure members are moved over the characters.
