Abstract: An automatic focusing camera which is equipped with a taking lens system changeable in focal length between at least two different focal lengths: a relatively short focal length suitable for wide-angle photography, and a relatively long focal length suitable for telephotography. When the taking lens system is changed to have the relatively short focal length, the taking lens is further changed to be able to take close-up photographs and the automatic focusing is simultaneously changed to cover a short subject distance range between, for example 0.1 and 1.0 m.

Abstract: A camera of the type in which a taking lens is orientable relative to the camera body comprises a lens holder, a light-impervious member connecting the lens holder and camera body for allowing at least an axial movement of the taking lens, and a supporting member attached to the lens holder for detachably connecting a flash unit.

Abstract: A display device for a camera has a display panel with a digital display unit having seven display segments disposed in a figure-eight shape. The digital display unit displays the number of exposed frames or other exposure information, and in addition, a portion of display segments is utilized for display or for indicating an alarm condition of the camera. In order to clearly recognize the display or alarm of the camera conditions, a character or symbol representative of the display content or alarm content is disposed near a display segment used for both numerical display, and camera condition display or alarm. A display of the film winding state is performed by flashing the laterally elongated display segments positioned between patterns formed sideways of the digital display unit and symbolizing a film supply section and a film winding section.

Abstract: A camera having a provision for multiple exposures comprises an exposure mode setting member for selectively setting the camera operation either to an ordinary-exposure mode or to a multiple-exposure mode, a switch member which is rendered operative only when the exposure mode setting member selects the multiple-exposure mode and a one-frame film advance mechanism actuated by the operation of the switch member. This camera further comprises a data recording device for recording data such as the date on a film once every frame and a mark recording device for recording the same number of marks as there have been multiple exposures upon every exposure.

Abstract: A film wind-up control apparatus of a camera in which a film is transported in zigzag direction passing around at least a guide roller located before an exposure station, is adapted to advance the film a predetermined length of the film when an exposure is made in a predetermined period of time and an extra length in addition to the predetermined length after the predetermined period of time has elapsed, so as to advance that part of the film which was previously positioned around the guide roller, beyond the exposure station. The apparatus is also adapted to indicate the number of possible exposures with one decrement every other occurrence of the extra length of film advance. In this way, film that has become permanently curled around the guide roller never comes to rest in the exposure station; but at the same time, the count of remaining frames is kept accurate.

Abstract: A film wind-up apparatus is incorporated in an interchangeable film magazine adapted to receive a film which has a backing paper including a leading end portion. The winding device automatically winds up the leading end portion only after the magazine is attached to a camera having a winding motor, film is loaded in the film magazine, the back cover of the magazine is closed, and a light-shielding plate is removed. Upon completion of the winding operation, a photosensitive portion of the film faces the exposure aperture, and a camera so equipped is ready to make exposures.

Abstract: A reflex camera having a reflex mirror and a light-blocking plate which are pivotally mounted for swinging movement so as to move between a viewing position and a photographing position. The reflex camera has a driving mechanism including an electric motor for causing the swing-up and -down movement of the reflex mirror and the light-blocking plate between the above-mentioned two positions, and a position-detecting device to detect the moved positions of the reflex mirror and the light blocking plate so as to control the speed of rotation of the electric motor according to the detected positions, thereby to prevent shocks and vibrations on the reflex mirror and the light-blocking plate.

Abstract: A cooking appliance using a gas fuel as a heat source and having an appliance body includes comprising a temperature sensor installed in a heating chamber, a control circuit adapted to be actuated by the output from the temperature sensor and to operate according to three working temperatures, namely, a preset temperature, an upper limit temperature and a lower limit temperature, the arrangement being such that when the temperature in the heating chamber being detected by the temperature sensor reaches the upper limit temperature, the main burners are completely closed; when it reaches the preset temperature, the firing of the main burners is reduced by half; and when it reaches the lower limit temperature, the main burners are fully opened, thereby effecting fine temperature control, the firing rate being automatically adjusted according to variations in external conditions affecting the heating chamber temperature, thereby maintaining the preset temperature throughout the heating operation to provide a sati
