Abstract

PURPOSE: To improve working efficiency when scanning a line scanner head in an inverse subscanning direction and reading picture data by reading a picture data by reading a picture data from a memory in an address order contrary to the address order with which picture data are written into the memory.
CONSTITUTION: If the line scanner head 1 scans in a sequential subscanning direction while it scans in a main scanning direction so as to read the pictures of an fixed original, the read picture data of one screen are written into the memory 2, and picture data are read from the memory 2 in the same address order as the address order with which picture data are written into the memory 2. If the head 1 scans in the inverse auxiliary scanning direction while it scans in the main scanning direction of the line scanner head 1 so as to read the pictures of the fixed original, the read picture data of one screen are written into the memory 2, and picture data are read from the memory 2 in the address order contrary to the address order which picture data are written into the memory 2. Picture data can be obtained when the line scanner head 1 returns in a start position.
