Title: Temperature compensating system for thermal recorder
Inventor: KUMAZAWA YUKIYOSHI
IPC: B41J2/36
Filed: 1987-04-03
Abstract: PURPOSE:To make it possible to compensate for the temperature of a device without using a temperature sensor, by controlling an energization time width for each individual heat generating element through a thermal head-driving part according to first temperature compensation information, and controlling a common driving voltage for a plurality of the heat generating elements according to a second temperature compensation information. CONSTITUTION:When an output from a first driving history compensating circuit group 5 is 1, a control is conducted so as to reduce an energization time width for a corresponding heat generating element by a thermal head-driving part 2. When the output is 0, a control is conducted so as to increase the energization time width for the corresponding heat generating element. When an output from a second driving history compensating circuit 6 is 1, all of the heat generating elements are driven by a low driving voltage by the driving part 2. When the output from the circuit 6 is 0, all of the heat generating elements are driven by a high driving voltage. By thus using two kinds of driving history compensating circuits in combination, it is possible to eliminate the need for providing a thermal head with a temperature sensor.
