An image forming apparatus includes a cover member which is openable and closable with respect to main assembly of the image forming apparatus; and an image reading portion, movable to first and second positions, for reading an image of an original. The cover member is movable to first and second open positions with respect to the main assembly. The image reading portion is initially rested at the first position as the cover member is moved from a closed position to the first open positions, and then is movable from the first position to the second position in interrelation with movement of the cover member from the first open position toward the second open position.

A diode type ultraviolet sensor having a layered-structure body including a conductive layer composed of a sintered ceramic body having conductivity and a semiconductor layer composed of an oxide semiconductor including ZnO. The semiconductor layer is disposed on a principal surface of the conductive layer and forms a heterojunction with the conductive layer. The ultraviolet sensor is used in such a condition that the semiconductor layer is positioned at a light-receiving side irradiated by ultraviolet rays. The semiconductor layer is preferably composed of a sintered body. The sintered body serving as the conductive layer and sintered body serving as the semiconductor layer are preferably formed by co-firing. Terminal electrodes are provided on a principal surface and the other principal surface of the layered-structure body, respectively.

An ink cartridge, which is removably set in a printer, has an ink chamber storing ink, an absorbent chamber containing a sponge that absorbs the ink from the ink chamber and holds it, and a fuel chamber storing a liquid fuel to be supplied to a fuel cell of the printer. The fuel chamber is located outside and adjacent to the ink chamber, so that the ink stored in the ink chamber is kept in a constant temperature range. Data on residual amounts of the ink and the fuel in the ink cartridge are detected by a residual ink detector and a residual fuel detector of the printer, and are written in a memory card that is removably attached to the ink cartridge.

A camera has a lens system that includes a lens barrel incorporating therein an image taking lens, the lens barrel being variable in a barrel length between a collapsed state in which the barrel length is relative short and a photographic state in which the barrel length is relative long. The lens barrel comprises a light quantity control member that controls quantity of photographic light passing through the image taking lens, and a light quantity control member saving and advancing mechanism that provides such a control that when the lens barrel changes over from the photographic state to the collapsed state, the light quantity control member is saved from a photographic optical axis, and when the lens barrel changes over from the collapsed state to the photographic state, the light quantity control member is advanced to the photographic optical axis.

In a digital camera, a solid state imaging device is used to catch subject light so that an image signal is created. The digital camera contributes to effectively implementing further thinness in such a manner that a part of image taking lenses is saved to a suitable position at the time of the collapse. Both the rear elements lens and the focus lens are revolved between a position on the optical axis and a saving position coming into a hollow portion beside the CCD solid state imaging device, or between the position on the optical axis and a saving position in which the front elements lens, the rear elements lens and focus lens form a line substantially on a plane.
