<p>PURPOSE:To feed easily the numerical data from an operation part even when a cursor is shifted by providing a ten-key part to the operation part. CONSTITUTION:An operation part 5 contains a switch 2-1 which selects a numerical data input mode or a cursor shift mode and ten keys 7. These keys 7 consist of key tops which are shifted down with manual pushes and the switches which produce input signals in response to the shifts of said key tops. The keys 7 are operated while the switch 2-1 is kept off to feed the numerical data to a main body. A cursor shift mode is selected while the switch 2-1 is kept off, and the input is impossible with the numerical data. Under such a condition a switch 2 is turned on and the part 5 is shifted. Thus a cursor can be shifted.</p> |
