PURPOSE: To realize the stable maintenance of the power of laser light, which is emitted from a laser light emitting part and incident upon the ink sheet on the recording paper wound round a rotary drum through an optical means by suppressing the change such as the change of situation, the environmental change or the like. CONSTITUTION: This heat transfer type printing equipment is equipped with a laser light emitting part 31 for emitting laser light changing in response to an information signal, a power detecting light receiving part 38 for detecting the power of laser light, which is emitted from the laser light emitting part 31 and incident through optical means 32, 29 and 25 upon an ink sheet IS overlapped on a recording paper RP wound round a rotary drum 20, and a laser power controlling means for controlling light-emitting power at the laser light emitting part 31 on the basis of the detected output obtained from the power detecting light receiving part 38. |
