Abstract: Drain structure of an electric connection box is provided that is capable of preventing penetration of water with simplicity. According to the drain structure of the electric connection box, since a pair of engaging leg portions of a waterproof lid is engaged in a peripheral part of a communication hole of the drain portion and a lid portion covers the upper part of the water discharging hole, the water that penetrates through to the inside of the electric connection box through the communication hole and water discharging hole of the drain portion can be dammed in use of lid portion of the waterproof lid and can be prevented from gushing into the electric connection box. As a result, since it is possible to prevent the terminal portion of a wire such as a wire harness or the like, which is arranged to run from moistening with the water, penetration of water can be surely prevented.

Abstract: A digital single-lens reflex camera includes a first mirror for reflecting part of a light beam coming from a subject through a photographing optical system and transmitting the remaining light beam. The reflected light beam is used for detecting the focus state of an imaging light beam, and the transmitted light beam is used for performing live view display. For example, the first mirror can be configured as a movable mirror in the digital single-lens reflex camera. This enables continuous live view display using the transmitted light beam on condition that the movable mirror is down while detecting the focus state using the reflected light beam. In addition, phase-contrast AF can be adopted for detecting the focus state.

Abstract: A camera has a rangefinder device having an optical system constituted by a plurality of optical elements and a diopter adjustment mechanism capable of adjusting the observation diopter of the rangefinder device by operation by the user from outside the camera. In addition, there are provided an operating member that operates the diopter adjustment mechanism and an adjustment mechanism that effects adjustment such that the observation diopter of the rangefinder device is at a predetermined value when the operating member is in a prescribed position. By this means, a camera having a diopter adjustment mechanism whereby the relative positional relationship of the operating member and driven member can always be ensured such that the observation diopter gets equal to the predetermined observation diopter that is to be set when the operating member is arranged in the prescribed position. This can be realized by a straightforward construction.

Abstract: A camera of this invention incorporates a finder unit capable of changing its magnification corresponding to any one of plural zoom lens barrels (first, second lens barrels) each having different zoom range. When installing the finder unit, first, a positioning pin is inserted into a positioning hole in a rotary frame so as to hold the lens barrel in standard zoom condition. Then, a finder positioning pin is inserted into a cam gear positioning hole and main body positioning hole in finder cam shaft so as to hold a finder lens at a variable magnification position corresponding to the standard zoom condition. With that condition, a zoom driving gear arrangement is meshed with a driving gear portion and cam gear in a rotary frame so that the lens barrel and finder are assembled with each other. This camera realizes reduction of product development term and production cost.

Abstract: A strobe camera with a strobe emission section movable between a first position in which strobe light can be emitted and a second position different from the first position. A strobe state detection unit outputs a first strobe state signal when the strobe emission section is in the first position, and a second strobe state signal when the strobe emission section is in the second position. A camera state detection unit outputs a first camera state signal when the camera is in a photographing-permitted state, and a second camera state signal when the camera is in a photographing-prohibited position. A control unit causes the camera to execute a warning operation when the camera state detection unit outputs the first camera state signal and the strobe state detection unit outputs the second strobe state signal, and causes the camera to stop execution of the warning operation and perform an exposure operation when the first strobe state signal is output instead of the second strobe stage signal.
