Title:
SYSTEM FOR TRACING OBJECT AND CONTROLLING ITS OPERATION
Document Type and Number:
Japanese Patent JP3971477
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate the necessity of physical contact or the like with a traced object by judging the operation of the object based upon plural temperatures in a local area of the object having heat gradation and correcting the operation of the object based upon the operation information.
SOLUTION: In a paper handling system 10 for precisely moving paper supported by an air jet e.g. a conveyer including plural air jets 26 can support, move and guide paper 12. An infrared-ray laser 31 induces local temperature gradation 34 on the paper 12 by directing a laser beam 32 and a heat sensing device 40 provided with plural temperature sensors measures plural temperatures in the local area having heat gradation on the paper 12. An operation calculating device 50 connected to the device 40 judges the operation of the paper 12 based upon the plural measured temperatures and an operation controller 52 corrects the operation of the paper 12 based upon operation information received from the device 50. Consequently the speed and position of an object can be traced without requiring physical contact and permanent marking.
