Backup method for photo printer data

Abstract

Abstract PURPOSE:To simplify work, and to attain backup of a data at low cost by inserting an external auxiliary storage card from a slot which is provided on a printer body, coupling both connectors of a CPU and the card, and executing read and write operations of a data. CONSTITUTION:From a slot 3, an external auxiliary storage card, for instance, a RAM card or a ROM card 6 is inserted, and a connector 7 of the card 6 is connected to a connector 8 of a CPU substrate 4. A CPU5 in the CPU substrate reads a data consisting of an address bus 10 and a data bus 11 of a RAM9 in the substrate, and writes it to a RAM in the external auxiliary storage card 6. On the contrary, in case of sending the data which is accumulated in the card 6, into the CPU substrate of the printer body, the CPU in the CPU substrate reads the data of the RAM or the ROM in the card 6, and writes it to the RAM in the substrate.
