Abstract

The present invention relates to a sensing device, which comprises a housing, a support, a grating module, a first roller, a second roller and a control unit. When the medium contacts the second roller member, the second roller member drives the first roller member to move the supporter relative to the housing according to the thickness of the medium, so as to change the distance between the firstroller member and the grating wheel of the grating module with respect to the location of the shell. And when the media drives the second roller member to rotate, the second roller member drives thefirst roller member to drive the grating wheel to rotate. The control unit determines whether the medium travels at a predetermined speed according to a corresponding light sensing signal generated bythe grating module when the grating wheel rotates, thereby reminding the user of the progress of the medium.

Description

technical field [0001] The invention relates to a sensing device and a business machine thereof, in particular to a sensing device for judging whether paper jams and a business machine thereof. Background technique [0002] Business machines (such as scanning machines or copiers, etc.) have been widely used in modern life to help people deal with clerical affairs. In order to ensure that paper jams can be eliminated in a timely manner, the paper feeding channel in the MFP is usually equipped with a sensor for judging the paper traveling status, so as to improve photocopying or printing efficiency. The current common sensor is usually a cantilever type or a connecting rod type, which is in contact with the paper when the paper is traveling, so as to generate a corresponding signal, and then judge the state of the paper traveling. However, sometimes this kind of sensor will affect the paper travel, or even cause paper jams, which is inconvenient to use. Contents of the inve...
