Patent ID: 7226223

Claim:
A camera comprising: a main body defining a pair of film chambers on opposite sides of an exposure opening comprising a first chamber for receiving a film cassette having a central spool to which film is secured and a second chamber for receiving a second film container into which film is pre-wound prior to use, a drive shaft having an end which extends into the first chamber for engaging the spool, a shutter mechanism including a movable shutter blade, a shutter release assembly having a user-accessible shutter button and shutter release lever having a primed position from which depression of the shutter button acts to cause shutter release lever to strike the shutter blade and moving to a discharged position, the shutter button being depressible against the action of resilient means, a motorized film advance assembly comprising a motor operatively connected to the drive shaft to drive the drive shaft in one direction and activated on closing of a contact pair, wherein the contact pair comprises a first spring contact acted on by said shutter button and a second spring contact bent away from the first spring contact and maintained spaced therefrom by the shutter release lever in the primed position, the first spring contact being bendable away from the second spring contact through depression of the shutter button and returning through its resilience, the shutter button also acting to displace the shutter release lever to the discharged position whereby the second spring contact moves towards the first, spring contact, the spring contacts touching after depression and subsequent release of the shutter button, activating the film advance motor.
