发明名称 Photographic camera
摘要 A photographic camera for drawing out a film from a film cartridge loaded therein and winding up the film around a cylindrical take-up spool comprises a film hold-down mechanism installed to the back cover and disposed in a passageway of the film so as to hold down the film toward the take-up spool at a position before a generating line of the cylindrical take-up spool closest to the back cover when the back cover is closed. When the back cover is fully closed and locked, the camera automatically actuates a built-in motor to rotate the take-up spool to wind reliably the film around the take-up spool.
