ABSTRACT:
An input device may be used with the information processing apparatus and the like, and provides an improved ease of operation in moving the cursor on the display screen.The input device includes a set of cursor keys1that, when activated, cause the cursor to move on a display section8, a cursor key activation detect means2, a rotary operation device3, a rotary operation device activation detect means4, and a cursor movement information generator means5that responds to the detect results from the cursor key activation detect means2and from the rotary operation device activation detect means4, and provides respective output signals that cause the cursor to move as indicated by the received detect results, depending upon whether only the cursor keys are activated or both the cursor keys and the rotary operation device are activated.Using the input device allows the operator to cause the cursor to move around and across the display screen, quickly and/or with any speed specified by the operator.
