| Function |
This calculating machine has a manual printer. It consists of a complete keyboard of 10 rows of numbers from 1 to 9 with, from right to left, units, tens, hundreds, etc. On the right-hand side are 5 keys for the Sub-total (S), Total, Non Add, R (Repeat) for multiplication and C for typing errors. Printing is performed using an ink ribbon. Addition is automatic, achieved by typing in the numbers one after another; the crank enables them to be printed out. For multiplication, performed by repeated additions, the user first presses the R (Repeat) key. |
