Abstract
A detection apparatus includes a cover, touch sensors that output a detection signal based on contact on the cover, and a controller that acquires the detection signal. The controller detects contact on the cover based on the detection signal and judges whether input of a predetermined pattern is provided based on time variable data of the detection signal outputted by each touch sensor from when the contact on the cover starts until the contact on the cover ends.
