Claims
- 1. A lens-fitted photo film unit, in which a film housing is pre-loaded with unexposed photo film, said film housing including a photograph-taking device including a taking lens and a shutter mechanism, said flash device including a flash-emitting section driven in response to actuation of said shutter mechanism for emitting flash light toward a photographic field within a predetermined range, a main capacitor for storing charge to be discharged in said flash-emitting section, and a flash circuit board having a flash circuit for controlling charging of said main capacitor and flash emission of said flash-emitting section,
- wherein said flash-emitting section is slidably attached to said flash circuit board, said flash-emitting section including two rails arranged parallel to one another, said flash circuit board including a projecting portion, said flash-emitting section and said flash circuit board being arranged such that said rails are slidably disposed on opposite sides of said protecting portion.
- 2. The lens-fitted photo film unit of claim 1, wherein said flash-emitting section is slidably attached to said flash circuit board such that d.gtoreq.r while said flash-emitting section is used, and that d<r while said flash-emitting section is unused, where
- d is a distance between a center of said flash-emitting section and an optical axis of said taking lens, and
- r is a radius of a virtual circle having a center located on said optical axis of said taking lens, and meeting a condition:
- GN<1/(0.37-{0.73.multidot.tan.sup.-1 (r/400)}/2.5.degree.)
- where GN is a guide number of said flash device.
- 3. The lens-fitted photo film unit of claim 2, wherein said lens-fitted photo film unit further comprises an aperture stop control device disposed in a light path defined through said taking lens, for setting an aperture stop of said taking lens for standard photography smaller than an aperture stop of said taking lens for flash photography.
- 4. The lens-fitted photo film unit of claim 1, wherein said flash-emitting section is slidable horizontally with respect to said flash circuit board.
