Abstract: An inspection machine (M) for checking particularly bottles (F) comprises a conveyor (T) for transporting the bottles along an arched path (2) and past at least one inspection device (A1-A4) associated with the arched path, and at least one illumination device (3) which is arranged below the arched path and shines light through the bottles from below and upward. The conveyor (T) presents a disk (1) which can be driven in rotation, and whose top side (9) presents a standing surface for the bottom (15) of each bottle to be transported, which stands directly on the surface, where the disk (1) is constructed so that it is transparent at least in some area.
