Abstract
Abstract A dot printing device includes a head (25) having a plurality of head pins (P1 to P9), a dot driver (2, 22) for selectively energizing the head pins (P1 to P9) according to dot data, a character generator (10), and a data processing unit (1, 3, 4) for causing N-bit dot data constituting designated character data to be generated sequentially by the character generator (10) according to input character designation data, and supplied to the head driver (2, 22). The data processing unit (1, 3, 4) causes a plurality of N-bit dot data corresponding to the input character designation data to be generated from the character generator (10) according to input character designation data and italic printing data, and supplies the lowest bit of the N-bit dot data and (N - 1) bits with predetermined delay times with respect to the lowest bit to the head driver (2, 22).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A dot printing device comprising: a head (25) having N dot printing elements (Pl to P9) arranged in a row; head driving means (2, 22) for selectively energizing said dot printing elements (Pl to P9) according to dot data; and data processing means (1, 3, 4, 10) for supplying a plurality of dot data constituting character data designated by input character designation data, each dot data setting the operating state of each of said N dot printing elements (P1 to P9), and supplying said dot data to said head driving means (2, 22) for each printing cycle, characterized in that said data processing means (1, 3, 4, 10) generates a plurality of dot data constituting character data designated by said input character designation data for each printing cycle according to input data including said input character designation data and italic printing data, divides N bits constituting each dot data into n (n i N) bit-groups and supplies said n bit-groups sequentially to said head driving means (2, 22) in n consecutive printing cycles in an italic printing mode.
Claim 2
Dependent Claim
178 words
A dot printing device comprising: a head (25) having N dot printing elements (Pl to P9) arranged in a row; head driving means (2, 22) for selectively energizing said dot printing elements (Pl to P9) according to dot data; and data processing means (1, 3, 4, 10) for supplying a plurality of dot data constituting character data designated by input character designation data, each dot data setting the operating state of each of said N dot printing elements (P1 to P9), and supplying said dot data to said head driving means (2, 22) for each printing cycle, characterized in that said data processing means (1, 3, 4, 10) generates a plurality of dot data constituting character data designated by said input character designation data for each printing cycle according to input data including said input character designation data and italic printing data, divides N bits constituting each dot data into n (n i N) bit-groups and supplies said n bit-groups sequentially to said head driving means (2, 22) in n consecutive printing cycles in an italic printing mode.
