1. A pad type input device comprising:
- an operation surface which includes a scroll area operated by an operation body;
a detector that is operative to detect a touch position of the operation body placed on the operation surface as positional information on a coordinate plane; and
a data processor that is operative to acquire an operation signal obtained by the detector to perform a predetermined process,wherein the data processor executes a scroll lock timer routine when the operation body placed on the scroll area is in a stop state where the operation body does not move, even after a predetermined time elapses,wherein the scroll lock timer routine includes specifying a scroll speed information, outputting a scroll signal that moves display contents in a predetermined scroll direction, the scroll signal including the scroll speed information, and setting the scroll lock timer which determines a duration of time until next scroll lock timer routine is executed, andwherein the scroll lock timer routine is repeatedly executed based on the scroll lock timer until the operation body is not placed on the scroll area.

Abstract
A pad type input device is provided. The pad type input device includes an operation surface which includes a scroll area operated by an operation body. A detector is operative to detect a touch position of the operation body placed on the operation surface as positional information on a coordinate plane. A data processor is operative to acquire an operation signal obtained by the detector to perform a predetermined process. The data processor outputs a scroll signal that moves display contents in a predetermined scroll direction when the operation body placed on the scroll area is in a stop state where the operation body does not move, even after a predetermined time elapses.

5. A scroll controlling method of a pad type input device including an operation surface which includes a scroll area operated by an operation body, a detector which detects a touch position of the operation body placed on the operation surface as positional information on a coordinate plane, a data processor which acquires an operation signal obtained by the detecting means to perform a predetermined process, and a display which displays display contents processed by the data processing means, the method comprising:
-
setting a scroll lock timer which determines a duration of time until next scroll lock timer routine is executed; determining whether the operation body placed on the scroll area is in a stop state where the operation body does not move, even after a predetermined time elapses wherein the scroll lock timer routine is repeatedly executed based on the scroll lock timer until the operation body is not placed on the scroll area, and outputting a scroll signal for moving the display contents in a predetermined scroll direction to an operating system when it is determined that the operation body is in the stop state.
