定結果の信頼性を低減させてしまう可能性がある。Generally, the bottom of the can is formed in a concave spherical shape in order to improve the pressure resistance. In order to measure the amount of depression at the bottom of the can, it is necessary to measure the amount of depression at the position where the bottom is maximally depressed, that is, the position at the center of the bottom. However, when measuring the amount of depression at the bottom of the can using a depth gauge or a depth micrometer as described above, the measuring element is brought into contact with the center of the bottom of the can by visual inspection of an operator. A shift may occur, and it is difficult to accurately measure the amount of depression at the center of the bottom. In order to eliminate such a displacement of the measurement position, the axis of the can body, that is, the standard of the can body is obtained, and a mechanism is used to keep the can body in a constant posture, so that the measurement can be accurately performed at the bottom center of the can body. The child is abutted to eliminate deviation of the measurement position by eye measurement. Such a mechanism determines the axis of the can body based on the cylindrical side plate of the can body. However, since the side plate of the can body is formed through punching, drawing, and the like, deformation such as bending, warping, and twisting is likely to occur, and the axis of the can body is determined based on such a side plate of the can body. When the axis is determined, the side plate is deformed when the axis is determined, and it is difficult to accurately determine the axis. If the axis cannot be determined with high accuracy, the measurement position will eventually shift as in the case of using a depth gauge, etc., so that an accurate measurement result cannot be obtained and the reliability of the measurement result is reduced. May be lost.

できる。According to this invention, first, after the container to be measured with the opening facing downward is placed on the bottom receiving surface of the support means, the pressing plate of the pressing means presses the bottom of the container from above toward the bottom receiving surface. Press down on. Since the bottom receiving surface is formed in a concave conical surface shape corresponding to the concave shape of the bottom of the measured container, when the bottom of the measured container is pressed against the bottom receiving surface by the pressing plate,
The bottom of the container to be measured follows the bottom receiving surface, the bottom of the container to be measured is in close contact with the bottom receiving surface, the axis of the container to be measured is substantially parallel to the vertical direction, and the axis of the container to be measured is The center of the surface and the center of the holding plate are at the same position in plan view. That is, the axis of the container to be measured and the axis of the tracing stylus provided at the center of the holding plate are parallel and at the same position in plan view. In this state, if the amount of protrusion of the measuring element, which is in contact with the bottom of the container to be measured, from the lower surface of the pressing plate (the surface in contact with the container to be measured) is obtained, the amount of depression at the bottom of the container to be measured is obtained. By the centering mechanism constituted by the supporting means and the pressing means, the axis of the container to be measured and the axis of the tracing stylus can be matched in a plan view, and the bottom of the container to be measured has a bottom corresponding to the bottom shape. Since the container is pressed against the receiving surface, the container to be measured is not deformed such as distortion. Then, in a state where the axis of the container to be measured is aligned with the axis of the probe, the amount of protrusion of the probe contacting the bottom of the container to be measured from the lower surface of the holding plate is obtained. The amount of depression at the center can be accurately measured. Therefore, since the amount of depression at the bottom of the container to be measured can be measured at a correct measurement position (the center of the bottom of the container to be measured), an accurate measurement result can be obtained, and the reliability of the measurement result can be improved.

It is comprised including. Here, the driving means 51 is constituted by an air cylinder. Using such a zero point setting means 50, the zero point setting of the measuring instrument 40 is performed as follows (see FIG. 3). First, the bracket 23 is raised by the lifting / lowering means 22, and is raised until the pressing plate 26 of the pressing means 20 and the measuring device 40 are located above the gauge plate 52. Next, the gauge plate 52 is moved to immediately below the holding plate 26 by the driving means 51. In this state, the holding plate 26 and the measuring device 40 are lowered by lowering the bracket 23 by the lifting / lowering means 22. Eventually, after the lower surface of the holding plate 26 comes into contact with the upper surface (reference surface 52A) of the gauge plate 52,
Further, when the bracket 23 is lowered, the holding plate 26
Can not descend any further, so bracket 2
