The invention provides an apparatus and method for imaging markings on
cartridge cases. It provides for the taking of two images of the cartridge
case with light for illumination projected at the cartridge case from two
different predetermined angles. In a first version, two different light
sources are set at the two different predetermined angles. In a second
version, one light source is moved between two different positions to
project light at the two different predetermined angles. In a third
version, the device holding the cartridge case is rotated between two
different positions so light projects at the cartridge case from the two
different predetermined angles. In a fourth version, the holding device
rotates the cartridge case between two different positions so that light
projects at the cartridge case at the two different predetermined angles.
In another aspect, the invention provides diffuse light for the taking of
the images. In yet another aspect, the invention provides a cartridge case
holding device which can rotate the cartridge case about a longitudinal
axis.
