Abstract: A first body houses a photoconductor is provided with a second body openably and closably attached to the first body. Additionally, a unit is provided to be swingable with respect to the second body such that an exposure surface of the unit is disposed at an exposure position opposing the photoconductor when the second body is closed. The exposure surface of the unit is disposed at a retreated position facing toward the rotary shaft of the second body when the first body is opened. Since the exposure surface of the unit faces toward the rotary shaft of the second body when the second body is opened, the exposure surface is not exposed to outside of the second body.

Abstract: In a document lighting device, each of the plurality of the light emitting elements arrayed in a light source unit is arranged in a vicinity of a focal point on a cross section in a sub-scanning direction of a long-sized lens, and a convergent point is placed at a location departing a predetermined distance in the main scanning direction from a location on the surface to be illuminated included in the sub-scanning cross section.

Abstract: An imaging media cartridge for use in an imaging apparatus includes a first imaging media reservoir chamber and a second imaging media reservoir chamber. A removable barrier is disposed between the first imaging media reservoir chamber and the second imaging media reservoir chamber. By removing the removable barrier, a reserve of imaging media can be provided from the second imaging media reservoir chamber to the first imaging media reservoir chamber. In one embodiment the imaging media cartridge is a toner cartridge. In another embodiment the imaging media cartridge is a liquid ink cartridge.
