7. The 1.5V AA battery cell powers up the oscillator. (Energy Processing) The 1.5V AA battery cell powers up the oscillator. (Energy Processing) The first transformer generates the AC Voltage to 200-300 volts. (Energy Processing) The first transformer generates the AC Voltage to 200-300 volts. (Energy Processing) When the main Capacitor is charged it is indicated by a LED light and its voltage is applied to the flash tube terminals. (Signal Processing) When the main Capacitor is charged it is indicated by a LED light and its voltage is applied to the flash tube terminals. (Signal Processing) The trigger switch is pressed to activate the shutter and the flash charge. (Signal Processing) The trigger switch is pressed to activate the shutter and the flash charge. (Signal Processing) Advance spin wheel is spun to advance the film and wind the shutter. (Energy Processing) Advance spin wheel is spun to advance the film and wind the shutter. (Energy Processing) Frame counter is advanced to show the number of pictures left. (Material Processing) Frame counter is advanced to show the number of pictures left. (Material Processing) Film and shutter are in position to use the camera. (Material Processing) Film and shutter are in position to use the camera. (Material Processing) User looks through the viewfinder to select the image. (Energy Processing) User looks through the viewfinder to select the image. (Energy Processing) The shutter opens and the voltage travels to a second transformer. This new and much higher voltage is then put through the flash tube to create a flash. (Energy Processing) The shutter opens and the voltage travels to a second transformer. This new and much higher voltage is then put through the flash tube to create a flash. (Energy Processing) The shutter closes and the image is stored onto the camera. (Energy Processing) The shutter closes and the image is stored onto the camera. (Energy Processing) Camera Operation
