    摘要： A camera which permits change-over between different light measuring systems is disclosed. The camera includes a first light measuring element which measures light coming from an object to be photographed and an operational amplifier responsive to the element. A light measurement information producing circuit is included for producing a light measurement information signal for exposure computation. A change-over device is connected between the light measurement information producing circuit and the operational amplifier. The change-over device is arranged to be shiftable between a first position wherein the operational amplifier is connected to the light measurement information producing circuit and a second position wherein the operational amplifier is not so connected. An accessory device is attachable to the camera body. The accessory device includes a second light receiving element for measuring light from the object within a light measurement range different from that of the first light receiving element and another operational amplifier responsive thereto. A terminal is responsive to the signal from the latter operational amplifier. The terminal is disposed at the second position of the change-over device so that the signal from the latter operation is applied to the light measurement information producing circuit when the change-over device is in this position.

    摘要： In the camera disclosed, an electromagnetic actuator is responsive to a timing pulse of short duration from an exposure control circuit for controlling the closing movement of a shutter. A permanent magnet may accidently be left latched and hold the rear curtain in cocked position after the timing pulse because of possible damage to an electromagnetic control circuit as a result of a battery short circuit. This may cause the film to fog during subsequent winding or rewinding. To prevent this, an indicator produces a visible indication either in the field of view of the camera finder or, in the case of remote shutter operation, outside the camera housing, that the rear curtain must be manually unlatched.

    摘要： A pulse generating apparatus which generates rectangular wave signal by opening and closing of a mechanical contact and has a differentiation circuit to output such pulse signal as corresponding to the rising position of said signal. Said apparatus has a rectangular wave generating means to generate rectangular wave signal by opening and closing a mechanical contact, a differentiation circuit to receive the rectangular wave signal from said rectangular wave generating means and to differentiate the same, and a high impedance element connected to the discharge circuit within said differentiation circuit. By this the discharging time constant factor of the differentiation circuit becomes large, sharply reducing the chattering pulse which parasitises to the rectangular wave signal.

    摘要： In a slide projector a plurality of slide films contained in a tray are successively selected and shifted to a projected position. A switch is provided which controls movement through a clutch to a running motor of each slide film between its tray-stored position and its projection position and also movement of the tray itself. This switch serves also as a switch for resetting a timer which holds each slide film in its projected position for any desired time.
