The mounting 62 which is shown in plan view in Figure 2, is a basket-like rigid member preferably molded as an integral member out o~ plastics material. The mounting 62 includes a~
bottom wall or floor 68 and a pair of outwardly inclined planar end walls 70 and 72 at opposite ends of the floor 68.

The two mirrors 58 and 60 and the lens system 56 can be mounted with facility on the mounting 62 with the resulting optical alignment assured and before the mounting component is installed within the machine housing 30. The mounting of the `respective mirrors onto the respective end-walls is effected with the mirrors parallel to the said end walls respectively.
The height of the partition 80 is selected to be less than the overall height of the basket-like support 62 so that a flangad well 94, provided as a part of the imaging assembly for holding liquid toner or for supporting a toner containing cart-;~ 15 ridge 96, can rest upon the upper edge of the partition 80.

notch 98 can be provided in each wall 76, 78 opening to the upper edge to receive said well 94. ~amp 100 and reflector 102 ;~ therefor may be accommodated secured to said well 94.
A pair of flanges 104 and 106 are formed respectively ` 20 aong the well 94, flange 106 having an L-s~aped cross-sectional configuration~ Flange 104 mounts the lamp and reflector and flange 106 i9 employed to seat the housing carrying the electro-photographic operating stationsO

If a different mirror arrangement having the mirror pair disposed at angles other than 45, is required, the mounting component 62 can be dislodged easily from its snap~in connection with the housing 64 and replaced with a similar struc-ture having its respective mirror supporting walls formed with a different angular inclination.
Additional supporting flanges also can be provided in ~; the moldea structure ad~acent the border of the notched areas - 98 so as to provide greater support for-the well 94 seated bridging the pair of connecting walls.
