Methods, systems and devices are described for detecting a position-based attribute of a finger, stylus or other object with a touchpad or other sensor having a touch-sensitive region that includes a plurality of electrodes. At this time, photographs are taken a plurality of times at a predetermined time interval. In one embodiment, the audio processing architecture is readily extensible. This reflectance is achieved by producing a back contact having a highly reflecting metal separated from an absorbing layer with a dielectric layer. The moving member moves from the second position to the first position by the biasing force of the biasing member when a rotation of the fixing belt is stopped.
