Abstract
A photographic recording apparatus is provided having a housing body, and a process cartridge unit including a photoconductive drum and a developing device and which is removably mounted on the housing body. The cartridge unit includes a first and a second frame which are pivotable about a rotation axis of the drum relative to each other, and a biasing member for biasing the two frames to thereby hold the frames in a first relative angular position. The housing body includes a portion for holding the cartridge unit such that the two frames are held in a second relative angular position, which is established by pivoting the two frames from the first relative angular position against a biasing action of the biasing member. The first and second frames each having holes or openings that are initially misaligned, cooperate in an overlapping fashion to provide at least one opening through which a portion of the drum is exposed outside the frames, when the frames are placed in the second relative angular position. Each opening is closed when the frames are placed in the first relative angular position.
