A portable image scanner capable of selecting a manual document loading mode in which a cover member is united to a scanner body to feed a cut-sheet document through a document passage defined between the united scanner body and cover member for scanning the document, or a self-propelling mode in which the cover member is separated from the scanner body to move the independent scanner body on a thick document such as a book. The scanner body has a document sensor for detecting the cut-sheet document placed in the document passage in the manual document loading mode, and the thick document in the self-propelling mode to prevent the scanner body moving on the document from falling out of the edge of the thick document.

A camera with a taking lens system changeable in focal length between a relatively long and a relatively short focal length, which has an exposure control meter comprising a masking member disposed in front of a photoelectric element to provide an electric exposure control output, and formed with first and second openings for allowing light that has passed therethrough to fall on the photoelectric element at different incident angles. A light stop member is movable to cover or uncover the second openings upon changing the taking lens system between the relatively long and relatively short focal lengths. Upon changing the taking lens system to the relatively short focal length, the light stop member is moved to uncover all of the first and second openings so as to increase the quantity of light falling on the photoelectric element and to permit that light to fall at an increased incident angle; and, on the other hand, upon shifting the taking lens system to the relatively long focal length, the light stop member is moved back so as to cover only the second opening means while uncovering the first openings, thereby to decrease the quantity of light falling on the photoelectric element and to permit that light to fall only at a decreased incident angle.
