Abstract
Abstract Object identifying device, e.g. a bottle receiving device, comprising a transport apparatus for transporting the objects such as bottles, an identifying device with a data processing unit for identifying and accepting bottles having certain given shapes, and a recording device for recording accepted bottles. The identifying device comprises a principally stationary illuminating device for illuminating the bottles, a detector for examining the bottles, and a conveyor for moving the bottles past the detector. A mirror system is interposed between the illuminating device and the detector, with which the optical length of the entire system can be increased without increasing the structural dimensions thereof.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
82 words
Device for identifying objects, comprising illumination means for illuminating the objects, a detector for examining the illuminated objects, said illumination means and detector being situated opposite one another, means for increasing optical length of said device from said illumination means to said detector without increasing structural dimensions of said device, which comprise a mirror system situated between said illumination means and detector in a horizontal direction, whereby reflections of the objects by said mirror system do not turn in a vertical direction.
Claim 2
Dependent Claim
82 words
Device for identifying objects, comprising illumination means for illuminating the objects, a detector for examining the illuminated objects, said illumination means and detector being situated opposite one another, means for increasing optical length of said device from said illumination means to said detector without increasing structural dimensions of said device, which comprise a mirror system situated between said illumination means and detector in a horizontal direction, whereby reflections of the objects by said mirror system do not turn in a vertical direction.
Claim 3
Dependent Claim
98 words
Device for identifying objects, comprising illumination means for illuminating the objects, a detector for examining the illuminated objects, means for conveying the objects to be identified past said detector, with said illumination means and detector positioned on opposite sides of said conveyor means, and means for increasing optical length of said device from said illumination means to said detector without increasing structural dimensions of said device, which comprise a mirror system situated between said illumination means and detector in a horizontal direction, whereby reflections of the objects by said mirror system do not turn in a vertical direction.
Claim 4
Dependent Claim
98 words
Device for identifying objects, comprising illumination means for illuminating the objects, a detector for examining the illuminated objects, means for conveying the objects to be identified past said detector, with said illumination means and detector positioned on opposite sides of said conveyor means, and means for increasing optical length of said device from said illumination means to said detector without increasing structural dimensions of said device, which comprise a mirror system situated between said illumination means and detector in a horizontal direction, whereby reflections of the objects by said mirror system do not turn in a vertical direction.
Claim 5
Dependent Claim
