Lens-fitted photo film unit with flash device

A lens-fitted photo film unit including a main body pre-loaded with photo film, a flash unit, secured to said main body, for emitting flash light to a photographic field, an exposure opening, formed in said main body, for introducing light from said photographic field to said photo film, said light extending axially through said exposure opening, and a shutter mechanism, secured to said main body, for opening and closing said exposure opening, said lens-fitted photo film unit comprising:

• a charger switch for causing said flash unit to store charge upon being turned on;
• a changeover plate directly slidably movable to first and second set positions in a plane transverse to an axis of said light;
• a small diameter opening and a large diameter opening formed in said changeover plate, said small diameter opening having a diameter smaller than a diameter of said exposure opening, set at said exposure opening when said changeover plate is in said first set position, for stopping down said exposure opening, said large diameter opening having a diameter larger than said diameter of said small diameter opening, set at said exposure opening when said changeover plate is in said second set position;
• and
• a linking mechanism for allowing turning on and off said charger switch when said changeover plate is in said first set position, and for forcibly turning on said charger switch when said changeover plate is in said second set position.

• an aperture stop changer, shiftable to first and second set positions, for stopping down said exposure opening when in said first set position;
• a charger member, linearly slidable among first, second and third mode positions upon being operated externally, for turning off said charger switch when in said first mode position, and for turning on said charger switch when in said second and third mode positions;
• and
• a linking mechanism for shifting said aperture stop changer to said first set position when said charger member is in said first and second mode positions, and for shifting said aperture stop changer to said second set position when said charger member is in said third mode position.
