<p>PURPOSE:To contrive to reduce the cost of the system by a constitution wherein, in a heat sensitive recording driving system, a shift register to energize a heat generating body by receiving a picture information from RAM is directly connected to the driver of a heat sensitive recording head. CONSTITUTION:In a heat sensitive recording driving system, a RAM11 which transfers a picture information to a driver and a shift register 12 which receives the picture information from the RAM11 and energize a heat generating low resistor 13 are installed. And a write-in time of the RAM11 and a read time of the picture information for the bits of the shift register 12, reading from the RAM11 are, respectively, defined as a shorter time than a color development heating time, and further, a clock period of time to be stopped when the picture information is read in the shift register 12 is defined as a longer time than a color forming heating time. Consequently, the driver can be connected directly to the shift register 12 and both a stopping diode and a latch circuit are unnecessitated.</p> |
