摘要:
A media transport system for detecting metallic objects in media to be input into the media transport system, comprising: an input tray configured to hold media to be fed into the media transport system; one or more rollers configured to convey the media from the input tray and along a medium transport path, the one or more rollers driven by one or more motors; one or more induction sensors positioned proximate to the medium transport path, wherein the one or more induction sensors are configured to detect presence of metallic material and output a metallic detection signal; a processing unit in communication with the induction sensor, the processing unit configured to receive the metallic detection signal and further configured to analyze the signals and determine whether the media contains a metallic object; the processing unit further configured to detect the presence of a medium jam in the media transport system, and wherein the processing unit is configured to disable the motors from reversing direction in response to a detected medium jam when the media contains a metallic object.
摘要:
A system and method of detecting the presence of metallic objects in media to be conveyed in a medium transport system is disclosed. One or more metal detectors are included in the medium transport system to detect the presence of metal in the medium being transported. Signals from the metal detectors are sent to a system processor, which analyzes the signals, and produces proximity, duration, and/or intensity values therefrom. One or more microphones may also be included which detect the sound created as the medium is being transported. The processor computes sound values from the microphone signals, and analyzes the computed sound values along with the proximity, duration, and/or intensity values in order determine if the conveyance of the medium along the transport path should be stopped due to the presence of metal in the media or a jam occurring within the medium transport path.
摘要:
The invention provides a media transport system for detecting metallic objects in media to be input into the media transport system, comprising: an input tray (110) configured to hold media to be fed into the media transport system; one or more rollers (120,220) configured to convey the media from the input tray (110) and along a medium transport path; one or more induction sensors (215) positioned near an entry point of media from the input tray into the medium transport path, wherein the induction sensor (215) is configured to detect presence of any metallic material and output a metallic detection signal; a processing unit in communication with the induction sensor, the processing unit configured to receive the metallic detection signal and further configured to analyze the signals and determine whether the media contains a metallic object.
