Abstract: In a camera having such an information indication member as a scale plate, a pointer, etc. to indicate photographing informations such as a diaphragm aperture value, a shutter value, etc., and other conditions of the camera within a finder, and an illumination device for enabling said informations to be seen in a dark place. A finder illumination device is provided to clamp the indication member of an exposure meter as the inside of the finder is illuminated for preventing the exposure meter from making erroneous indication when the illuminating light is made incident into the light receiving element of the exposure meter positioned near the finder optical path.

Abstract: A video recording device is specified, which has an image-sensor device for converting an optical image into an electrical signal, a shutter for blocking the light which is incident onto the image-sensor device, a signal-generator device for forming periodic signals which are produced in order to read the electrical signal out of the image-sensor device periodically, a switch for inputting a command in order to operate the shutter, a first time-transmitter device which is set in operation by a predetermined, periodic signal which is produced after operation of the switch, and a shutter-control device which starts to open the shutter once a time duration which is predetermined and calculated by means of the time-transmitter device has elapsed. The video-recording device makes it possible, by means of the first time-transmitter device, to prevent any delay in the operation of the shutter and the like. The video-recording device is furthermore equipped with a shutting-detection device, which detects a displacement of the shutter from an open state to a closed state, and with a blocking device which prevents the reading (which is caused by the signal-generator device) until, after the start of a freeze-frame video recording process, the output signal of the shutter-detection device is received. Using this design, any ... … Original abstract incomplete.

Abstract: The present invention relates to a camera having an exposure control device designed so that the light measurement, the exposure condition determination and the photographing operation are carried out by means of a release means including an electromagnet element to be controlled by means of a plural number of switches operating successively with the release operation of the camera. The invention is characterized in that the time at which the output signal of the control circuit for controlling the operation of the camera after the light measurement in accordance with the magnitude of the output signal of the light measuring means is controlled so as to be delayed in such a manner that a correct operation can be obtained even if the light measuring time is short.

Abstract: The disclose circuit energizes a magnetic winding of a shutter actuating device. A constant voltage circuit is connected across the magnetic winding, or between the power supply terminal of the magnetic winding and a basic potential to ensure that the response of the armature of the actuating device to the output of a timing circuit is stabilized despite variation in the voltage of an electrical power source. This produces the advantage of substantially improving the accuracy of exposure control, because the closing operation of the shutter is controlled through movement of the armature.
