Title:
HEATER CONTROLLER FOR FIXATION
Document Type and Number:
Japanese Patent JP3118117
Kind Code:
B2
Abstract:
PURPOSE: To stabilize heating fixation independent of the change of the condition of a power source and the change of the processing condition.
CONSTITUTION: Whether the continuous platemaking processing of the intermittent platemaking processing is decided based on the output of a photosensitive material detecting sensor 54 by means of a microcomputer 58 and the measured voltage value of a voltage measuring means 52 is obtained according to the correcting reference for the applying voltage previously set and the cut-ting rate of the supplying power to a heater is obtained based on the decided result. Solid state relays 60, 62, 64 are ON/OFF controlled by means of the microcomputer 58 so that the power supply to the respective heaters 540 are instantaneously and partially interrupted according to the obtained cutting rate of the supplying power to a heater. Consequently, the applied voltage is compensated in accordance with the measured voltage value even when an AC input voltage fluctuates and moreover the applied voltage on a heater is compensated according to the processing condition even in the case of either continuous fixation processing or intermittent fixation processing.
