Abstract

An input device includes a touch pad which is rotatably supported and has an upper surface as an input operation surface, a switch element located on a lower side of the touch pad, and a control unit configured to be able to perform control such that during an operation of an operation body (finger, etc.) being moved on the input operation surface while the input operation surface is pressed downwardly by the operation body to cause the switch element to be in an ON state, the ON state is continued even if the ON state is released in a state the operation of the operation body on the input operation surface is kept.

Claims

1. An input device comprising:

a movable touch pad rotatably supported and having an upper surface as an input operation surface;

a switch element located on a lower side of the touch pad; and

a control unit configured to perform a continued-ON state control during an operation of an operation body moving on the input operation surface and pressing the input operation surface downwardly to cause the switch element to be in an ON state, the continued-ON state control maintaining the ON state even if the ON state of the switch element is released while the operation of the operation body continues on or in a vicinity of the input operation surface.

2. The input device according to claim 1, wherein the control unit maintains the continued-ON state control under a condition that an operation coordinate (X,Y) of the operation body is within a specific region defined on the input operation surface.

3. The input device according to claim 1, wherein the control unit maintains the continued-ON state control under a condition that the ON state of the switch element is released when the operation body is located within a specific region defined on the input operation surface, and an operation start position of the operation body is located in a non-specific region outside the specific region.

4. The input device according to claim 2, wherein the specific region is set in a vicinity of a hinge portion rotatably supporting the touch pad.

5. The input device according to claim 1, the control unit maintains the continued-ON state control under a condition that a movement distance of the operation body on the input operation surface is greater than a threshold L.

6. The input device according to claim 5, wherein the threshold L is changeable according to a moving direction of the operation body.

7. The input device according to claim 1, wherein the control unit releases the continued-ON state control based on a predetermined condition.

8. The input device according to claim 7, wherein the predetermined condition includes at least one of:

a continuation time of the ON state;

a number of times of data indicating that the operation body does not touch or come close to the input operation surface; and

a number of times of polling.

9. The input device according to claim 1, wherein a drag operation is continued on a display body displayed on a display apparatus by the continued-ON state control maintained by the control unit.
