PURPOSE:To eliminate a wiring between a document editing apparatus body and a sensor to improve assembly workability by providing a temperature correction circuit for correcting the temperature difference between the temperature of the printing head part of a printer and a temperature detected by the sensor for given periods of time directly after closing of power and breaking thereof. CONSTITUTION:For the purpose of correcting the temperature difference between the temperature of the printing head part 12 of a printer and a temperature detected by a sensor 11, a controller 1 is provided with a power ON-OFF time temperature correction circuit 9 for outputting a temperature correction signal 9a for correcting a sensor part temperature signal 8a only for a certain period of time at the time of closing the power of an output device 5. When this temperature correction circuit 9 is provided, it is possible to solve the problem of the temperature difference between the temperature of the printing head part 12 of the printer and the detected temperature of the sensor varying with the elapsed time after closing of the power at the time of providing the sensor on the control board 13 of the document editing apparatus body. Therefore, it is unnecessary to have much data before hand within a control circuit 6 so that a wiring between the sensor and the control board 13 of the document editing apparatus body can be eliminated and assembly workability can be improved. |
