<p>PURPOSE:To shift a cursor on a character display screen of a display quickly and easily. CONSTITUTION:A pulse is generated out of a manual pulse generator 4 by means of a rotary dial type operator 3. A mechanical key of an input key unit 21 on a control panel 20 is operated and simultaneously it judges a fact that a select switch 14 is changed over to a manual pulse handle feed mode, whereby the generated pulse is outputted to a motor control part 2, operating a motor 1. In contrast with this, it judges another fact that the mechanical key of the input key unit 21 is not operated, whereby the generated pulse is outputted to a cursor control part 8, thus a cursor 7 on a character display screen 6 of a display 5 is shifted in this way.</p> |
