An exhaust gas aftertreatment device for an internal combustion engine producing the exhaust gas comprises an inlet configured to receive the exhaust gas, an outlet from which the exhaust gas exits the device, an aftertreatment element disposed between the inlet and the outlet, and a flow modification mechanism. An intake device conveys material into a bale forming chamber surrounded by a bale forming mechanism. Since illumination light is entered into the fly-eye lens in a state of inclining with respect to the fly-eye lens, the number of superimposition patterns on the fly-eye lens is increased and illuminance non-uniformity in illumination light is suppressed. The device includes at least one storage device positioned within the interior volume, and at least one communicative connection extending from the at least one storage device to a communicative socket accessible external to the electromagnetically shielded enclosure.
