摘要：An image scanner 30 is provided with a pair of buffers 54 and 55 which have thesame amount of storage area of eight bytes. Except for the first writing operation towrite the first eight bytes to the first buffer 54, writing operations and transferringoperations are performed simultaneously. That is, data is written into the first buffer 54while data is retrieved from the second buffer 55, and data is written into the secondbuffer 55 while data is retrieved from the first buffer 54. Data is thus retrieved from thebuffers 54 and 55 in alternation and transferred to the host computer 10.
