A data transfer control device and electronic equipment that make it possible to implement high-speed data transfer while observing restriction that prevent the traversing of page boundaries. The elongate body is of a length which is substantially greater than it is wide, and the pin portion is adapted to be inserted through a locating hole in the jig and into a locating hole in the work piece to locate the work piece. A memory, such as a shift register, may be used to store and then grayscale levels to be written to adjacent pixels are compared and if a difference between these grayscale levels exceed a certain value then at least one of the grayscale levels is modified.
