ABSTRACT:
A mounting system for a developer unit in an electrophotocopier having a photoreceptor mounted on a drum for assuring proper alignment and pressure between the developer unit and the photoreceptor drum. The mounting system comprises a fixed platform having a rectangular slot located midway between the ends thereof, said slot having a length extending perpendicular to the axis of the photoreceptor drum, a developer unit slidably mounted at either end on said fixed platform, the developer unit having a base plate with an aperture in alignment with the rectangular slot, a pair of spacer wheels coaxial to and slightly larger in diameter than the applicator shell on the developer unit rotatably mounted on either end of the developer unit, means for urging the spacer wheels against the photoreceptor drum, and a locking and guiding device removably insertable in said rectangular slot in said fixed platform. The locking and guiding device includes a rotatable pin having a cap portion and a shank portion, the shank portion being reciprocably slidable in both the aperture and the slot, a compression spring located beneath the cap portion and above the base plate and surrounding the upper part of the shank portion of the pin, and a cam-lock fixedly secured to the bottom of the shank portion having a configuration such that the cam-lock may pass through the rectangular slot and upon rotation be locked into sliding engagement with the length of the rectangular slot.
