<p>PURPOSE:To drive a heat sensitive recording head with a simple circuit configuration by a method wherein after data are arrayed in a new order by using a microcomputer, a data set upto the last step is made feasible sequentially. CONSTITUTION:When data are entered sequentially as 1, 2, 3..., a microcomputer 5 arrays the data newly by every 128 bits and distributes data to FIFO memories 6-9 in a 2 bit unit with skipping 2 bits sequentially as in 1, 2, 5, 6... and the data upto 126 are distributed. Next thereto, the residual data are distributed as in 3, 4, 7, 8... and 128 bits are arrayed newly. And further, the data from 129 to 156 are distributed and the FIFO memories 6-9 are filled completely. An electronic switch 10 sends the data stored in the FIFO memories 6-9 to shift registers 11-14, sequentially, and at the point when the data from 1 to 126 of the 2 bit unit with skipping 2 bits, namely, 64 bits of data are given, the thermal head is excited to record. Next thereto, in order to perform an interpolation of the 1st recording, data from 3 to 128 are outputted onto shift register 11-14 to perform the 2nd recording.</p> |
