PROBLEM TO BE SOLVED: To decide obviously whether a mask is accurate by applying the black-white inversion to the mask range that is set by a mask range setting circuit and outputting all black areas. SOLUTION: The mask data on a mask range setting circuit 2 are sent to a mask-inverting circuit 3, in response to a recording operation. The circuit 3 sets a mask-inverting instruction (S/W) by a control program and sends the inverted mask data to an OR circuit 4, in response to a recording operation. The circuit 4 secures an OR between the image data received from an image memory 1 and the inverted mask data received from the circuit 3 and sends the recording data to an LD(laser diode) light-emitting part 5 in response to a recording operation. The part 5 makes the LD emit the light, based on the recording data and in response to a recording operation. When the recording data are recorded on the photosensitive recording paper, the light emission output of the part 5 is exposed directly onto the recording paper and then developed, thereby completing the recording operation. |
