A spherical-article measuring apparatus has first and second support arms and a size detector. The first support arm has first and second ends. The first end can be brought in contact with a first curve section of a spherical article to be measured at one end of the diametrical line in the spherical article. The second end can be located spaced apart from and opposite to a second curve section of the spherical article at the other end of the diametrical line. The second support arm has a third end which can be brought in contact with a third curve section of the spherical article. The size detector can be brought in contact with the second curve section.

1. Field of the Invention
The present invention concerns an apparatus and a method for measuring a spherical article.
FIG. 1 is a perspective view of a spherical-article measuring apparatus constructed according to one embodiment of the present invention.
FIG. 2 is a front view of the spherical-article measuring apparatus shown in FIG. 1 being mounted on a ball.
FIG. 3 is a side view as viewed from an arrow III in FIG. 2, the dial gauge being omitted.
One embodiment of the present invention will now be described in detail with reference to the drawings.
FIGS. 1 through 4 shows an apparatus for measuring a spherical article constructed according to one embodiment of the present invention while FIGS. 5A and B illustrate the measurement of a spherical article.
Referring first to FIG. 1, there is shown a spherical-article measuring apparatus 10 which comprises a first support arm 12, a second support arm 14 and a dial gauge 16 used as a size detector. In this embodiment, a datum setter 18 is also used.
