An operation surface includes a pressing operation area and a sliding operation area. When a single operation body is detected in the pressing operation area by an operation position detection unit, an operation process is not performed if a first sliding movement amount of the operation body is equal to or less than a first threshold, and the operation process is performed if the first sliding movement amount is greater than the first threshold. When there is a plurality of operation bodies and at least one of them is detected in the pressing operation area, the operation process is not performed if a second sliding movement amount of the operation body is equal to or less than a second threshold, and the operation process is performed if the second sliding movement amount is greater than the second threshold. At this time, the second threshold is greater than the first threshold.
1. An input device comprising:
an operation surface;
an operation position detection unit that detects an operation position of an operation body on the operation surface;
a pressing detection unit that detects pressing of the operation surface; and
a control unit that receives an operation position detection signal from the operation position detection unit and a pressing detection signal from the pressing detection unit, respectively,
wherein the operation surface includes a pressing operation area provided on a front side of a sliding operation area,
wherein, when there is a single operation body which operates on the operation surface and the operation body is detected in the pressing operation area by the operation position detection unit, the control unit does not output a sliding operation input signal based on a first sliding movement amount if the first sliding movement amount based on the operation position detection signal of the operation body is equal to or less than a first threshold, and outputs the sliding operation input signal based on the first sliding movement amount if the first sliding movement amount is greater than the first threshold,
wherein, when there is a plurality of operation bodies which operates on the operation surface and at least one of the operation bodies is detected in the pressing operation area by the operation position detection unit, the control unit determines that the operation of the at least one of the operation bodies in the pressing operation area is as an unintended sliding movement and does not output a sliding operation input signal based on a second sliding movement amount if the second sliding movement amount, based on the operation position detection signal of the operation body which is detected in the pressing operation area, is equal to or less than a second threshold, and outputs the sliding operation input signal based on the second sliding movement amount if the second sliding movement amount is greater than the second threshold, and
wherein the second threshold is greater than the first threshold.
2. The input device according to claim 1 ,
wherein, when there is the plurality of operation bodies which operates the operation surface and a distance between a first operation body which is detected in the pressing operation area and an operation body other than the first operation body is greater than a predetermined value, the control unit determines that the first operation body unintentionally moved with the operation body other than the first operation body and the second threshold is set such that the second threshold is greater than the first threshold.
