Abstract:
A cartridge unit includes a first drum cartridge, a first cover member, a stopper, and a first cover erroneous insertion blocking portion. The first cover member is removably attached with the first drum cartridge and configured to be compatible in shape with a first holding portion of a first apparatus body so that the first cover member is guided and held by the first holding portion. The first cover erroneous insertion blocking portion is configured to permit the first cover member to be guided by the first holding portion by a first distance from a first insertion slot portion and to block a second cover member, which is removably attached with a second drum cartridge functionally different from the first drum cartridge, to be guided by the first holding portion in a range exceeding a second distance shorter than the first distance from the first insertion slot portion.

Claim (Index 1):
A cartridge unit comprising:\n a first drum cartridge functionally compatible with a first apparatus body and comprising a photosensitive drum for forming an image, the first drum cartridge being configured to be compatible in shape with a first guide portion of the first apparatus body so that the first drum cartridge is capable of inserting into the first apparatus body in an insert direction and of being pulled out of the first apparatus body in a pull-out direction opposite to the insert direction; a first cover member removably attached with the first drum cartridge and configured to shade the photosensitive drum, the first cover member being configured to be compatible in shape with a first holding portion of the first apparatus body so that the first cover member is guided and held by the first holding portion; a stopper provided on the first cover member and configured to restrict the first cover member from being inserted beyond a first distance from a first insertion slot portion of the first apparatus body; and a first cover erroneous insertion blocking portion configured to permit the first cover member to be guided by the first holding portion by the first distance from the first insertion slot portion and to block a second cover member, which is removably attached with a second drum cartridge functionally different from the first drum cartridge and is compatible in shape with the first holding portion, to be guided by the first holding portion in a range exceeding a second distance shorter than the first distance from the first insertion slot portion, wherein the first cover member is compatible in shape with a second holding portion of a second apparatus body with which the second drum cartridge is functionally compatible, and is blocked by a second cover erroneous insertion blocking portion if the first cover member is erroneously inserted to a second apparatus body with the first drum cartridge, and wherein the second cover member is guided and held by the second holding portion without blocking of the second cover erroneous insertion blocking portion, if second cover member is inserted into the second apparatus body with the second drum cartridge.
