Attitude sensor of inside of pipe inspection camera

摘要

(57) Abstract Objective To be effective to miniaturization, at the same time securely revolution of the cameraTry to be able make attitude recognize. Constitution To 1st body of revolution A resistor A1, A2 and A3Way are arrayed by ring condition, oppose to this 2ndBody of revolution D, to be unified with A by axis B, thisComing and conductive sphere C between body of revolution A and D in free state inserting and othersre ru. Conductive sphere C choice the resistor depending upon rotary positionIt means electricity to joint to body of revolution of 2.
