  • MECHANISM TO DETECT LINEAR MOTION USING CAM PATH
    Publication number: 20150097331
    Abstract: In a mechanism for detecting the size of media loaded in a media tray of an imaging device, the media tray includes at least one pair of media guiding members for alignment with the edges of the media. The media size sensing mechanism includes two racks operatively connected to the pair of media guiding members, a pinion positioned between the two racks, a cam structure attached to the pinion, and a sensor depicting the corresponding size of the loaded media. The cam structure defines an arcuate surface engaging a sliding pin of the sensor. The arcuate surface of the cam structure is configured to slide the pin linearly between a first extreme linear position and a second extreme linear position, as the cam rotates between a first extreme angular position and a second extreme angular position.
