<p>PURPOSE:To rearrange input picture signals in the power-on order of heating elements and to change the picture signals in order without altering a scanning circuit, by providing a buffer memory for storing picture signals temporarily and a read-only memory for specifying a write/read address of said memory. CONSTITUTION:The recording and scanning circuit of a thermal recording head is provided with the buffer memory 301 wherein picture signals from an input terminal 207 are stored temporarily through the 4th picture signal changeover switch 306 and a counter 302 which inputs a write address to the memory 301 through an address changeover switch 306. This counter 302 inputs a clock from a clock input terminal 209 and sends a read address of the ROM303 to the memory 301, and the switch 306 is changed over to a read side to output picture signals from the memory 301 through the 5th picture signal changeover switch 305. The input picture signals are rearranged in the power-on order of heating elements and then outputted, thus changing the picture elements in order without altering the scanning circuit.</p> |
