Abstract
A operation member drives an X encoder and a Y encoder. According to the output pulses of both encoders, a figure displayed on a screen moves or rotates. When a finger touches a touch-sensitive switch immediately after the operation member is operated, the figure continues moving or rotating on the screen at the same speed as the operation speed at which the operation member was operated. When the finger is released from the touch-sensitive switch, the figure stops moving or rotating. When the touch-sensitive switch is again touched, the figure resumes moving or rotating.
Claims6
A data input apparatus comprising:
- an operation member operated by a hand;
- an encoder for outputting a operation signal according to the operation of said operation member;
- signal storing means for storing the operation signal sent from said encoder;
- coordinate-data generating means for generating coordinate data according to the output of said signal storing means;
- detecting means operable by a hand;
- and
- control means for continuously outputting the operation signal stored in said signal storing means to said coordinate-data generating means while a detection state continues if said detecting means is set to the detection state by a hand when said operation member is being operated or immediately after the operation has been completed.
