摘要： PROBLEM TO BE SOLVED: To solve such problem that it is difficult to appropriately correct a parallax in strobe projecting range at electronic-flash photographing a close- distance subject. SOLUTION: In the camera provided with lens driving mechanisms 1 to 13 for zooming a photographic lens stepwise and focusing at each zooming step by using a lens driving cam member 2 where a zoom driving cam area and a focus driving cam area are alternately formed, and light distribution angle changing mechanisms 23 to 40 for changing the light distribution angle of the electronic flash device cooperatively with the zooming operation of the lens driving mechanism, the light distribution angle changing mechanisms are constituted so that they may be actuated interlocking with the focusing operation of the lens driving mechanism and the light distribution angle of the electronic flash device is changed so that the light distribution angle when a subject is at a short distance may become wider than that when the subject is at a long distance.

摘要： PROBLEM TO BE SOLVED: To easily retrieve optional data from plural data by providing a data retrieving means for directly reading the data stored in a data storage means and displaying it on a display means when the retrieval of the data is designated from the outside. SOLUTION: A CUP 1 reads personal data X to be recorded on film 7 which is inputted from a data input device 2 by a photographer. Next, data related to the personal data X is read continuously to the personal data X. When the personal data is selected by a retrieval switch for setting the retrieving condition of the personal data, the CPU 1 accesses to obtain the character variable of all the personal data stored in an EEPROM 3 in the Japanese syllabary order so as to successively display it on a liquid crystal display device 5. When data retrieval is selected by the retrieval switch, the CPU 1 accesses to obtain the character variable of all the personal data stored in the EEPROM 3 in the Japanese syllabary order so as to sequentially display it on the display device 5.

摘要： PROBLEM TO BE SOLVED: To provide a measuring apparatus devised not to worsen the measurement accuracy when a plurality of lenses for guiding beams of light to each of a plurality of photoelectric conversion elements are integrated so as to miniaturize each of various kinds of measuring apparatuses. SOLUTION: A semiconductor chip 2 is fixedly bonded to a housing 1 for holding the whole of the apparatus. A wall part 1b is provided in the housing 1 to prevent unnecessary beams of light from reaching a photometric sensor 3 and a distance measurement sensor 4 from the photoelectric conversion elements. A thick central position in a direction of an optical axis of a photometric lens part 9a for guiding the beams of light to the photometric sensor 3 is more shifted towards the sensor in the optical axis direction than a thick central position in an optical axis direction of a distance measurement lens part 9b for guiding the beams of light to the distance measurement sensor. The photometric lens part 9a and the distance measurement lens part 9b are united in this state to 9. A flange part 9c is provided for holding and fixing the photometric lens part 9a and the distance measurement lens part 9b to the housing 1. The flange part 9c is bonded and fixed to a holding part 1a of the housing 1. An antireflection coating 9d is provided to a surface of an outer diametrical face of each lens part formed by arranging the photometric lens part 9a and the distance measurement lens part 9b with the shift in the optical axis direction.

摘要： PROBLEM TO BE SOLVED: To eliminate the trouble where a stroboscopic device is driven at focusing, when simply interlocking the stroboscopic device with a lens barrel, because a zoom mechanism and a focus mechanism are integrated in a step zoom lens barrel. SOLUTION: This camera is provided with a lens drive mechanism conducting stepwise zooming and focusing at each zoom step of a photographing lens by using a cam member 2, where a zoom drive cam area and a focus driving cam area are alternately formed, strobe light emission parts 16, 17, 18 and 21 whose light distribution angle is varied, and light distribution angle interlocking mechanisms (35b, 32, 28, 23 and the like) which change the light distribution angle of the strobe light emission part, interlocked with operation for the zooming of the photographing lens in the lens drive mechanism and making the light distribution angle of the strobe light emission part constant, at operation for the focusing of the photographing lens in the lens drive mechanism.

摘要： PURPOSE:To perform highly reliable display in a finder visual field frame or the changeover of a finder visual field frame with simple structure by integrating a light shielding plate and a display part or a switching means. CONSTITUTION:A display part 2b integrally formed on the light shielding plate 2 displays whether or not it is a panoramic photographing state by advancing the indication part into the visual field frame 12a of a finder bottom board 12. In the case of performing panoramic photographing, the light shielding plates 2 and 3 form a panoramic image plane where the upper and the lower parts of the image plane are surely shielding from light at a position where their end faces abut on light shielding plate stoppers 1d and 1e. At such a time, the display part 2b advances into the visual field frame 12a by moving the light shielding plate 2 upward, and surely indicates that it is the panoramic photographing state. On the other hand, in the case of performing ordinary photographing by releasing the panoramic photographing, a panorama switching external knob is allowed to slide, so that the light shielding plates 2 and 3 are retreated to the outside of a camera main body surface frame 1a and the display part 2b is surely retreated to the outside of the visual field frame 12a, and displays that it is the ordinary photographing state.
