A coupling includes a main body, a rotatable member, and a seal member. A low-beam light distribution pattern is synthesized from a base light distribution pattern, formed by a projection-type lamp unit, and a pair of additional light distribution patterns, formed by light reflected from a pair of additional reflectors provided on right and left sides of a lamp unit body. The connecting assembly includes a first element mounted on the upper member, the first element having a cavity therein; a second element mounted on the lower member; and a connector having a first end captured within the cavity and a second end adjustably connectable to the second element. The container guide member can move between a first position at which the toner container is detachably attached and a second position at which the contents of the toner container can be discharged. A second plastic covering is arranged on an opposite side of the window and seals the second seam. The storage units are monitored to determine if the user picked up the goods at the chosen time slot.
