ABSTRACT:
A gradation recorder used with a thermal printer that produces image data, such as a television image, in the form of a hard copy. The recorder has shift registers corresponding to the heat-producing resistors in the thermal printer. A plurality of gate drivers have their outputs connected to the respective resistors. A decoder which converts its input in binary form into hexadecimal form is connected to each one input of the shift registers. Data items are successively stored in the shift registers. Then, clock pulses are applied to the shift registers to successively retrieve the stored data items. Every time each one bit of the data is retrieved, the gate drivers energize or de-energize their respective resistors to print one dot matrix having a desired shade or tone.
