摘要

When a power source of an electronic control type embroidery machine is switched on, all pattern data of a plurality of embroidery patterns stored on a ROM card is summarily written to either a pattern data memory of RAM (volatile memory) or a flash memory (involatile memory) without any instruction for storing the data. As a result, the ROM card can be detached during the embroidery sewing operation, embroidery sewing of the plurality of embroidery patterns is simplified and operational performance of the sewing operation can be improved.
