Abstract

A rotation sensor comprising a Y-shaped strip and a conducting strip is disposed in a digital imaging device. The conducting strip is disposed below the Y-shaped strip. The Y-shaped strip has two sensing arms and a fixed arm. A metal piece is disposed on each of the two sensing arms. When the sensing arm hangs down due to the weight of the metal piece to touch the conducting strip, the Y-shaped strip and the conducting strip will form a closed circuit and send out a signal. Whether the digital imaging device is rotated is determined based on this signal. Whether the device body is horizontal or vertical can thus be accurately and quickly determined. Moreover, because the detection is accomplished through gentle deformation or rotation of the sensing arms, there will be no noise during the detection process.
