Abstract
A sheet processing apparatus includes a plurality of coils that are provided in a feeding section which feeds a sheet that has been taken in into a transport path and that generate magnetic fields and a control section that determines, on the basis of differential values between signals output from the plurality of coils, whether a foreign object has entered the feeding section.
Claims16
A sheet processing apparatus, comprising:
- a plurality of coils configured to generate magnetic fields, the plurality of coils positioned at an interface of the sheet processing apparatus that is configured to receive a sheet that has been taken in and to feed the sheet into a transport path of the sheet processing apparatus;
- a plurality of kicker rollers configured to kick the sheet toward a gate configured to receive the sheet;
- and
- circuitry configured to determine, on a basis of differential values between signals output from the plurality of coils, whether a foreign object has entered the interface, wherein
- the plurality of coils are foreign object detection coils configured to output different signals depending on whether there is the foreign object nearby, and
- each of the plurality of coils is arranged to surround a corresponding kicker roller of the plurality of kicker rollers such that a portion of each of the plurality of kicker rollers penetrates an opening formed by each of the plurality of coils.
