PURPOSE:To make the boundary unremarkable with a simple constitution, by compensating the energy applied to thermal heads located at both ends of thermal heads constituting each block. CONSTITUTION:A DC voltage source 11 of a voltage V1 is inserted between a switching element Qb1 and ground. A DC voltage source 12 in voltage V64 is inserted between a switching element Qb64 and ground. The insertion of a positive voltage source 11 reduces a voltage applied to thermal heads h1-1, h2-1- h20-1 and the print by the heads is made a little thin. The insertion of a negative voltage source 12 increases the voltage applied to thermal heads h1-64, h2-64-h20-64 and the print by the heads is made a little thick. Thus, the values of voltages V1 and V64 are determined arbitrarily to make unremarkable the boundary. |
