Abstract: A CPU reads out image data from a frame memory line by line, performs logical addition of each bit of readout original image data corresponding to one line and a corresponding bit of each image data acquired by shifting the original image data by one to four bits, and thereby generates image data whose width has been enlarged by four bits. When writing the image data enlarged in the leftward and rightward directions in a ring buffer, the CPU generates image data on a transfer base material which has been enlarged in the upward and downward directions by copying or logical addition. A transfer base material transfer control section outputs the image data on the transfer base material written in the ring buffer for each line to a print head control section under the control of the CPU at predetermined timing.

In the state in which a probe is rotated in a predetermined rotation direction, the probe is inserted into a flange of a rear sub frame, thereby starting friction stir welding to weld the flange of the rear sub frame and a flange of a front sub frame positioned on the inner side of the rear side of a vehicle.

Then, the probe is sequentially moved in the direction of arrow R4?arrow R5?arrow R6, which is opposite to the direction of arrow R1?arrow R2.
