发明名称 Film feeding device
摘要 A mechanism, for feeding a film with a photographing information magnetic recording area, of a camera. The camera including the mechanism has a cartridge holder inside which a film cartridge housing the film in is set; an aperture for defining an exposure field on the film; a magnetic head for writing/reading the photographing information; a take-up spool around which the film fed from the film cartridge is wound; and a drive motor for feeding the film between the film cartridge and the take-up spool. Both the take-up spool and the magnetic head are installed on one side of the aperture, and both the cartridge holder and the drive motor are installed on the other side, opposite to the one side in view of the film feeding direction, of the aperture. The drive motor is mounted opposite to the aperture relative to the cartridge holder; therefore, a greater distance is secured between the magnetic head and the motor so that an electromagnetic noise generated from the motor during the writing/reading operation by the magnetic head is effectively reduced on a side of the magnetic head.
