Document Type and Number:
Japanese Patent JP2760919
Kind Code:
B2
Abstract:
A thermal recording apparatus capable of preventing in advance a thermo-sensitive recording medium or the apparatus from being excessively heated when the apparatus is defective in operation. When a failure in operation of a polygon mirror is detected by a scanning sensor, when a failure in operation of a motor is detected by an encoder or when jamming or the like of a thermo-sensitive recording medium S is detected by a pair of feed sensors, a controller outputs a malfunction signal to a solenoid. The solenoid, activated at all times, is de-activated by the malfunction signal thereby to cause the shielding plate to cut off a laser beam L. Thus, even if a failure in operation of the thermal recording apparatus is developed, the thermo-sensitive recording medium S and the thermal recording apparatus can be prevented from being excessively heated with the laser beam L.
