Abstract

An input apparatus has an input unit for receiving a pressure input, a load detection unit for detecting a pressure load on the input unit, a vibration unit for vibrating the input unit, and a control unit for controlling drive of the vibration unit 14 such that a click sensation is provided to an object pressing the input unit when the pressure load detected by the load detection unit satisfies a predetermined standard for receiving an input to the input unit. Thereby, a realistic click sensation similar to that obtained when a push-button switch is operated is provided upon operation of the input unit of a pressure type by an operator.

Claims

1. An input apparatus comprising:

an input unit for receiving a pressure input;

a load detection unit for detecting a pressure load on the input unit;

a vibration unit for vibrating the input unit; and

a control unit for driving the vibration unit with a single drive signal when the pressure load detected by the load detection unit satisfies a predetermined standard for receiving an input to the input unit, wherein

the drive signal has a frequency of 140 Hz or higher, and

the drive signal is used for a period determined in a range from 1/4 period to 5/4 period of the drive signal.

2. A control method of an input apparatus comprising an input unit for receiving a pressure input, a load detection unit for detecting a pressure load on the input unit and a vibration unit for vibrating the input unit, the control method comprising the step of:

driving the vibration unit with a single drive signal when the pressure load detected by the load detection unit satisfies a predetermined standard for receiving an input to the input unit, wherein

the drive signal has a frequency of 140 Hz or higher, and

the drive signal is used for a period determined in a range from 1/4 period to 5/4 period of the drive signal.
