PROBLEM TO BE SOLVED: To improve a liquid injection execution rate of a liquid injection device by improving DMA transfer efficiency through an input buffer in data transfer within the liquid injection device. SOLUTION: DMA transfer of record control data D2 from an interface circuit 27 to the input buffer 261 is executed by a DMA controller 23 while setting the DMA transfer start address of a DMA transfer destination to address A1, and the DMA transfer end address of the DMA transfer destination to address A5. The record control data D2 are successively stored in memory areas of address A1-address A2 (FBFFFFH) of the input buffer 261. Thereafter, the address of a virtual address space VA on and after FC0000H is decoded to the address of a real address space RA by an address decode circuit 262, and the remaining data of the record control data D2 are stored in the memory areas of address A3 (FA0000H)-address A4 as shown in the drawing.
