ABSTRACT:
In a camera provided with an openable and closable back lid, and a film easy load device for automatically taking up around a take-up spool a film leader portion drawn out of a film cartridge loaded into a film supply chamber, the film leader portion being formed by partially cutting away one side edge of the film, a film guide device comprises a pair of guide rails including a first rail in contact with the one side edge of the film and a second rail in contact with the other side edge of the film, the guide rails extending in the film feeding direction and forming a film passage channel therebetween, film departure preventing means projected from the substantially central position of the first rail toward the back lid and preventing the one side edge of the film in a state in which the leader portion is in contact with the take-up spool from departing outwardly from the passage channel, and a film pressure plate having an escape portion at a location corresponding to the film departure preventing means and adapted to contact the upper surfaces of both of the pair of rails when the back lid is closed, thereby maintaining the degree of planarity of the film in the passage channel.
