Abstract: PROBLEM TO BE SOLVED: To accurately detect the recess of the lower part of the side surface of a container by providing a means for comparing the difference of image shading integral value between adjacent measurement sections and a preset allowance. SOLUTION: A radiation address with the center of a container as the scanning center is generated by a generator 304 for a frame memory 301, the multiple-value shading image signal of a picture element corresponding to the coordinates is sent to a window gate circuit 307, and on the other hand, only the image signal for an aimed region is outputted to a fault detection circuit 312 by a pattern in a window memory 302 as needed. A fault detection judgment circuit 313 receives the number of detected faults by each radial scanning from the circuit 312, determines as a fault when the number of detections exceeds a preset allowance and outputs it to a total judgment circuit 319.  Then, the circuit 319 outputs a conforming signal and a nonconforming signal to the outside of a device via an output circuit 320 when the judgment result of judgment circuits 309, 311, and 313 at a previous stage all turns out to be conforming and in the other cases, respectively.

Abstract: PURPOSE:To eliminate the need for pits to relieve columns and to reduce the installation cost by making an upper frame freely fixable and separable by clamp mechanisms with respect to the columns. CONSTITUTION:In the starting state, piston rods 14 which also serve as the columns 12 receive hydraulic pressure in S chambers 21 of main pressurizing hydraulic cylinders 13 and are pressed against the top dead centers in the cylinder chambers and made in a fixed state. In this state, when the upper frame 2 falls and approaches up to the main pressurizing position state with respect to a lower frame 3, pressure oil is supplied to hydraulic oil chambers 18 of the clamp mechanisms 15 and the upper frame 2 is fixed on the columns 12. At the same time, pressure oil is supplied to P chambers 22 of the main pressurizing hydraulic cylinders 13 and while the columns 12 falling slightly, main pressurization is carried out. Accordingly, since only the upper frame 2 carries out vertical movement to approach and separate from the lower frame 3 and the columns 12 only carry out slight vertical movement for main pressurization, the need for the pits to relieve the columns 12 is eliminated.
