Abstract

PURPOSE:To scan a probing contact in a truckless manner and at least in a two dimentional manner, by means of a drive gear wherein tractor trucks each, consisting of a plural number of magnetic substances coupled together, are mounted at both sides of the drive gear. CONSTITUTION:A running member 21 is constituted such that a plural number of magnetic members forms a close loop so that it can run in a manner to firmly adhere to a surface of a drum part 1, and tractor trucks, mounted to both sides of a drive gear 16, are rotatively driven through driving rollers 50 and 51 from a motor. A test along a longitudinal weld line 10 is performed through the forward and backward movement of the drive gear 16 with the tractor trucks 35 operated. A test along a peripheral weld line 11 is conducted by changing the advancing direction of the running member 21 and running the drive gear 16. A scanning, being perpendicular to a weld line, is performed through movement of a probing contact 15 into an arm 29 held by an arm 33 extensing from the driving gear 16. The moving distance of the drive gear 16 is obtained as a position information by converting the number of revolutions of the motor into a pulse signal by means of an encoder.
