Multiple sheets feeding detection apparatus, sorter, and method of detecting multiple sheets feeding
First Claim
1. A multiple sheets feeding detection apparatus comprising:
- a passage detector that detects passage of a target object and outputs passage information, the target object being carried by carrier means and having an RFID tag attached thereto;
a management code detector that receives management code information wirelessly sent from the RFID tag and outputs the management code information; and
a controller that receives inputs of the passage information and the management code information, determines a carrier state of the target object in accordance with the passage information and the management code information, and outputs a multiple feed generation signal when multiple sheets feeding occurs.

Abstract
A multiple sheets feeding detection apparatus, sorter, and method of detecting multiple sheets feeding are provided which can ensure reliable detection of multiple sheets feeding without causing any damage to target objects and can increase the processing capability by high-speed detecting operations.
The multiple sheets feeding detection apparatus comprises a passage detector that detects passage of a target object, a management code detector that receives management code information wirelessly sent from an RFID tag of the target object, a controller that determines a carrier state of the target object on the basis of passage information and the management code information, and outputs a multiple feed signal when multiple sheets feeding occurs, and removal portion for removing the target object from carrier portion upon receipt of the multiple feed signal.
