Rotation sensor
First Claim
1. A rotation sensor system disposed inside a digital imaging device having a processor, said rotation sensor system being capable of detecting the rotation state of said digital imaging device when said digital imaging device is capturing a picture, said rotation sensor system comprising:
- a processor mounted on a circuit board;
a rotation sensor electrically coupled to said circuit board for sensing a rotation of said circuit board;
said rotation sensor including;
a Y-shaped strip having two sensing arms and a fixed arm for connecting said two sensing arms, a metal piece being disposed on each of said two sensing arms, said sensing arms being made of an electrically conductive material, wherein a first end of said fixed arm is integrally connected to an end of each of said two sensing arms and a second end of said fixed arm is fixedly disposed in said digital imaging device, said second end being electrically connected to said circuit board; and
a conducting strip disposed between said two sensing arms, said conducting strip being fixedly disposed in said digital imaging device and electrically connected to said circuit board, said Y-shaped strip and said conducting strip forming a closed circuit to send out a signal to said processor when one of said metal pieces on one of said two sensing arms touches said conducting strip, said processor thereby determining the rotation state of said digital imaging device based on said signal.

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.
