Abstract
A method and apparatus for detecting media type by aligning a media type detector onto a media, with sufficient force, in a media manipulation or sensing apparatus, such that the media type detector will accurately detect a type of media of a media when the media is tilted. A media manipulation or sensing apparatus, where the media type detector is arranged before a picking mechanism, with the media type detector including a force applying mechanism to apply force to a housing sled that is aligned onto the media, and with the housing sled being able to rotate with the media as the media tilts.
Claims30
A media manipulation apparatus, comprising:
- a housing sled including at least two light sensors;
- a force applying mechanism to force the housing sled into contact with a media;
- and
- a determining unit to determine a media type of the media based on a ratio of detected light intensities measured by the light sensors while the housing sled is in contact with the media.
A media sensing apparatus, comprising:
- a housing sled including at least two light sensors;
- a force applying mechanism to force the housing sled into contact with a media;
- and
- a determining unit to determine a media type of media based on a ratio of detected light intensities measured by the light sensors while the housing sled is in contact with the media.
A media type detector, for determining a type of media based on a ratio of a detected specular light intensity to a detected diffuse light intensity, comprising:
- a housing sled including at least a diffuse light sensor and a specular light sensor;
- and
- a force applying mechanism to force the housing sled into contact with a media during a detection of the detected specular light intensity and detected diffuse light intensity.
A method of media type detection, comprising:
- applying a media type detector into contact with a media, with the media type detector having a plurality of light intensity sensors;
- detecting at least two light intensities;
- and
- determining a media type of the media by comparing the detected light intensities.
