READER/WRITER FOR MEMORY CARD

摘要

PURPOSE:To prevent the elimination of data by permitting a micro computer to transfer data of a memory for buffer to a memory care when a source trouble occurs after signals are given and taken to/from an external equipment. CONSTITUTION:A secondary power circuit 8 is put in a reader/writer for memory card, and when the power trouble occurs after data of the memory card 7 has been transferred to a buffer memory 5, the secondary power circuit 8 inputs a power trouble detection signal E to the micro computer 4. When the signal is inputted, a control signal A from the micro computer 4 transfers data of the buffer memory 5 to the memory card 7 through a terminal for memory card 6 by the flow of the signals C1 and C2.
