Abstract

PURPOSE:To prevent the production in the secondary failure based on the mis- judgement of a memory capacity, by detecting the memory mounting capacity automatically, through the use of a memory clear processing with a clear routine. CONSTITUTION:A memory clear processing is executed according to a clear routine program stored in a memory device 1, and when the clear processing to the memory card 3-n at the final stage is finished, the renewal address as the result of address renewal processing of the clear address corresponding to the final address location of the memory card 3-n does not belong to any of memory cards 3-1, 3-2-3-n causing stop of the address renewal processing. Further, comparing the loading memory capacity data at present with the final clear address information of the memory card 3-n detected with the said clear end signal nonoutput state, and if they are coincided, the said final clear address, that is, loaded capacity data is stored in the fixed address on the memory device 1.
