Abstract
A lens-fitted photo film unit includes a main body. A cassette holder chamber in the main body contains a photo film cassette. A roll holder chamber in the main body contains a roll of photo film drawn from the photo film cassette. A front cover of transparent resin covers a front of the main body. A rear cover covers a rear of the main body. The roll holder chamber has a top wall portion and an end wall portion disposed farther from the cassette holder chamber. A first light-shielding ridge is disposed to project forwards from the rear cover and to extend horizontally, overlapped with the top wall portion, for blocking entry of ambient light at the top wall portion. A second light-shielding ridge is disposed to project forwards from the rear cover and to extend vertically, overlapped with the end wall portion, for blocking entry of ambient light at the end wall portion. The second light-shielding ridge extends to the first light-shielding ridge. Also, an exposure light path is formed through the front cover and the main body, for introducing object light to the photo film. A light-shielding ridge blocks entry of ambient light into the exposure light path through portions of the front cover outside the exposure light path. Furthermore, a taking lens is disposed in front of the main body. A lens opening is formed in the front cover in front of the taking lens, for introducing object light to the taking lens. A ring-shaped blocking projection portion is disposed inside an edge of the lens opening, for blocking advance of ambient light from the front cover to the taking lens outside a predetermined incident angle range.
