摘要： This invention is directed to a camera which has an information setting device including an information setting member rotatable around a display device. The information setting member is provided with a window member which covers the display device and through which the indiciation displayed on the display device can be seen. The display device is supported on a frame which defines a camera body in association with a cover member surrounding the frame, while the information setting device is supported on the cover member. Accordingly, the size of both devices can be made large without necessity of enlarging the camera body in proportion to the size of the devices. Further, both devices can be assembled independently from each other. Namely, the information setting device is mounted on the cover member which is still separated from the frame. Meanwhile, the display device is mounted on the frame. Finally, the cover member with the information setting device and frame with the display device are assembled. Accordingly, the devices are easily assembled, inspected and adjusted.

摘要： A flash photography system with a camera body and an electronic flash device incorporates first to third terminals in the camera body which are connectable to fourth through sixth terminals in the flash device. A signal is produced to distinguish between first and second modes wherein data is transmitted to the electronic flash device and data from the electronic flash device is transmitted to the camera body, respectively, and connected to the first terminal. Clock pulses control the data transmission and data is read from the electronic flash device and transmitted to the electronic flash device through the second terminal in response to the clock pulses. An initiating signal to cause production of artificial illuminating light from the electronic flash device is provided at the third terminal. In response to the distinguishing signal, selection is made between the first and second modes via the fourth terminal. The electronic flash device provides via the fifth terminal serial data to the camera body in response to the clock pulses through the fourth terminal. Data is read to the electronic flash device through the fifth terminal in response to pulses from the fourth terminal. The electronic flash device provides artificial illuminating light in response to the initiating signal through the sixth terminal.

摘要： A multi-point photometric apparatus for use in a camera or the like operative to measure the luminance of several divided areas in an objective field. Among the luminance signals produced by the photometric circuit for the several areas, a signal from one area which is used for automatic focus adjustment is designated as a reference value, and the maximum and minimum values of luminance signals and the differences of these from the reference value are evaluated. The reference value and differences in the form of digital data and information on the film latitude are processed with a microprocessor to calculate the exposure value. The exposure value is modified to an extend that the reference remains within the film latitude.
