摘要： The disclosed device winds film in a continuous rapid-sequence mode or a non-continuous single-frame mode. A disengagement arrangement responds to a winding completion signal after each frame is wound in the continuous mode and disengages the transmission during the subsequent shutter release, but allows the transmission to remain engaged in the non-continuous mode and at the end of a winding sequence in the continuous mode. According to one embodiment, the disengagement arrangement contains an electromagnet that also actuates the camera's shutter release in the continuous mode.

摘要： An apparatus for checking the voltage of a power source battery in a photographic camera is disclosed. In simple form, this apparatus comprises first and second series circuits connected in parallel with each other to the battery, the first one of which has a luminous diode and a resistor, and the second one of which has two luminous diodes and a resistor, the characteristics of the luminous diodes and resistors being so selected that, when the actual voltage is dropped from a predetermined level, a difference between the brightnesses of the luminous diodes of the first and second circuits results to apprise the camera operator of the drop in battery voltage.

摘要： A number of separate comparators compare respective analog inputs to a single reference waveform and turn off respective gates when the analog voltages achieve predetermined relationships to reference wave form. The gates pass pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. In one version the analog signals represent photographic data such as diaphragm aperture and shutter speed in a camera, and are digitized for display within the camera.
