Sewing machine pattern - has store to hold data in two groups with central switch to connect pattern keys to one of the groups

摘要

An electronic store, on the sewing machine, stores various pattern data of two groups. There are a number of push switches, to select pattern data, with a two-position switch mechanism to relate the switches to either the first or second group of data. The system allows the user to store the most frequently used patterns in one group; concentrating the other patterns into a second group for easier operation.
