Abstract

PURPOSE: To perform the gradation recording of a picture with high fidelity by putting serial or alternate heating elements to work by a control circuit composed of a threshold circuit, etc.
CONSTITUTION: Signals extracted by the higher threshold level of 1st threshold circuit 14 are all written to shift register 11. Signals extracted by the lower threshold level of 2nd threshold circuit 15 are alternately written to respective bits of shift register 11. Signals written in this way put selectively heating elements 2a, 2b,..., 2m to work through timing circuit 12 and driver circuit 13. At the higher level of recorded signals, adjacent heating elements operate in succession and at the lower level, every other one operates. In this way, the recording of a picture shaded according to the signal level can be attained with high fidelity.
