<p>PURPOSE:To simplify recognition with a coordinate input device by informing the coordinate designating states for setting area with different sound signals. CONSTITUTION:An original cover 2 is attached turnably at a prescribed position of the surface of a picture forming device main body 1 together with a coordinate setting tablet 3. An operating part 4 containing various types of keys and display devices is attached to the main body 1. At the same time, a coordinate designating tool 5 containing a touch pen, etc., is attached detachably to the main body 1. In this case, the set coordinate signals received from the tablet 3 are supplied to an odd-even discriminating part 6 as well as to a coordinate signal processing part 7. The processed signal received from the part 7 is supplied to an alarm control part 8 and the control signal is supplied to a buzzer 9 from the part 8. Then the part 8 outputs a 1st control signal to sound once the buzzer 9, a 2nd control signal to sound twice the buzzer 9, a 3rd control signal to sound finely the buzzer 9 and 4th control signal to sound continuously the buzzer 9 respectively in response to an odd designating frequency of coordinates, etc.</p> |
