Abstract
An input device includes an input accepting member, a base, a first pressure sensor, a weight, a second pressure sensor, and a processor. The input accepting member accepts a pressing operation. The input accepting member is attached to the base. The first pressure sensor on the base is configured to detect a pressure acting thereon by the input accepting member. The second pressure sensor on the base is configured to detect a pressure acting thereon by the weight. The processor is configured to: multiply an output value from the second pressure sensor by a ratio of mass of the input accepting member to that of the weight to obtain a correction value; and correct an output value from the first pressure sensor by using a correction value to extract an output value that relates to a pressing force applied to the input accepting member by the pressing operation.
