DEVICE FOR CONTROL OF LOADER OPERATION Russian patent published in 2007 - IPC G06K7/10 

FIELD: methods and arrangements for sensing record carriers.

SUBSTANCE: device comprises recorder whose output is connected with the computer and reflector. The plane of symmetry of the directivity diagram of the recorder lies in the plane parallel to the frontal plane of the device, can rotate around the horizontal axis perpendicular to the frontal plane of the device, and is optically connected with the reflector whose normal to the reflecting surface defines an angle with the plane of the symmetry of the directivity diagram. The angle is equal to half arctangent of the ratio of the reading zone length of the recorder to the width of the control zone. The device additionally has timer and selective detector. The axis of symmetry of the directivity diagram of the detector is inclined to the horizontal plane normal to the frontal plane of the device at an angle whose arctangent is equal to the ratio of the depth of the detecting zone to the height of the detecting zone.

EFFECT: enhanced labor efficiency and safety.
