Abstract
A camera body includes an aperture unit, having a picture-taking opening and guide rails for defining the position of a film in the direction of an optical axis with respect to the picture-taking opening, a cartridge chamber unit connectable with one end of the aperture unit, and a spool chamber unit connectable with the other end of the aperture unit. At least one of a film exit port of the cartridge chamber unit and a film entrance port of the spool chamber unit includes guide portions that define the position of a film in the direction of the width of the film that is paid out from a film cartridge.
Claims12
A camera body comprising:
- an aperture unit in which an aperture opening is formed;
- a separate cartridge chamber unit connectable with one end of said aperture unit and including a film exit port;
- and
- a separate spool chamber unit connectable with the other end of said aperture unit and including a film entrance port,
- wherein at least one of said film exit port of said cartridge chamber unit and said film entrance port of said spool chamber unit includes a guide portion that defines a position of a film in a width direction of said film that is paid out from a film cartridge loaded into said cartridge chamber and also defines a position of said spool chamber unit relative to said aperture unit when they are connected with each other.
A camera body comprising:
- a pressure plate;
- a separate generally planar aperture unit including an aperture opening,
- guide rails for defining the position of a film in the direction of an optical axis, and
- projecting portions for engaging with said pressure plate to define the position of said film on said guide rails;
- a separate cartridge chamber unit connectable with one end of said aperture unit and including a film exit port;
- a separate spool chamber unit connectable with the other end of said aperture unit and including a film entrance port;
- and
- a guide portion formed on at least one of said film exit port of said cartridge chamber unit and said film entrance port of said spool chamber unit for defining the position of said film in a width direction of said film that is paid out from a film cartridge loaded into said cartridge chamber unit and also defines a position of said spool chamber unit or said cartridge chamber unit relative to said aperture unit.
A camera comprising:
- an aperture unit including at least a picture-taking opening;
- and
- a separate film cartridge chamber unit connectable with one end of the aperture unit for housing a film cartridge,
- wherein said film cartridge chamber unit includes a guide portion for restraining the position of a film in a width direction of said film that is paid out from said film cartridge and also defining a position of said film cartridge chamber unit relative to said aperture unit.
A camera comprising:
- an aperture unit comprising at least a picture-taking opening;
- and
- a separate spool chamber unit connectable with one end of the aperture unit for housing a film pulled out of a film cartridge,
- wherein said spool chamber unit includes a guide portion for restraining the position of a film in a width direction of said film that is paid out from said film cartridge and also defining a position of said spool chamber unit relative to said aperture unit.
