摘要： An imaging device moves a taking lens in an optical-axis direction by a hollow stepping motor of a claw-pole type comprising a disk-shaped hollow magnet and stators. The magnet is disposed in a direction perpendicular to the optical axis. The stators are respectively adjacent to both surfaces of the magnet in the optical-axis direction. When the magnet is rotated, attractive force caused by the respective stators is applied in the optical axis direction. It is prevented that the magnet and a rotary barrel are attracted in the direction perpendicular to the optical axis. Thus, electric power consumption is prevented from increasing due to friction with upper and lower covers, and abnormal noise is prevented from occurring due to the friction.

摘要： A first lens holder is connected with a rotary barrel through a helicoid mechanism, and moves in an optical axial direction when the rotary barrel rotates. A second lens holder is connected with the rotary barrel through a cam mechanism. The cam mechanism is constituted of a cam portion that is disposed on a front end surface of the rotary barrel and cam followers that are disposed on a rear end surface of the second lens holder. The cam portion is formed to have sloped surfaces inclined along a circumferential direction and these sloped surfaces are in contact with the cam followers. When the rotary barrel rotates, the cam followers shift in the optical axial direction along the sloped surfaces, thereby moving the second lens holder back and forth in the optical axial direction.

摘要： A view frame changing apparatus of the present invention is constructed in which cam grooves formed at view frame pieces are arched by the predetermined curvature; thus the cam pins can smoothly slide over the entire area of the sliding area of the cam grooves without being caught in the cam grooves. Moreover, the cam grooves are formed in areas of acute angles in between the two diagonal lines of the image frame; therefore, the frame changing apparatus can be compact in size.

摘要： A hook of a cartridge-chamber lid is engaged with one end of an engagement lever to be kept in a closed position. The other end of the engagement lever is engaged with an intermediate lever attached to an upper face of a cartridge chamber. When a photo film is wound up, a winding-up lock mechanism comprising an urging gear, a lever member and a winding-up lock member prevents the intermediate lever from rotating, namely prevents the engagement lever from swinging to lock the cartridge-chamber lid. When the photo film is rewound, a rewinding lock mechanism comprising an urging gear, a lever member, a rewinding lock member and a torsion spring prevents the intermediate lever from rotating, namely prevents the engagement lever from swinging to lock the cartridge-chamber lid.
