PURPOSE:To make image information available efficiently and easily by setting up a read out region when reading radiation image information through the radiation image conversion panel. CONSTITUTION:The number of the picture element to be read at the top in the main scanning direction and the top line number to be read at the top in the sub-scanning direction, lengths in respective directions and picture element density are set in the region designation section 10 based on data input through a keyboard or other means of the region parameter input section 11. Designation of read out section is made based on the counting, as for the sub-scanning direction, of the main scanning synchronization signals with respect to the sub-scanning synchronization signals and, as for the main scanning direction, of picture element clock signals that are outputted for each picture element with respect to the main scanning signals. Needless to say, to shorten the time taken until the read out region is reached, the sub-scanning speed is taken into account when the top line number in the sub-scanning directino is set in the region designation section 10, saving time to read data in unnecessary read out region. Thus, much better use is made of the memory.
