A lens-fitted photo film unit as defined in claim 2, further comprising a charger button portion, movable with said changeover plate and extending from one end portion of said changeover plate closer to said charger switch, said charger button portion being resiliently deformable for turning on said charger switch upon being depressed externally when said changeover plate is in said first set position. 5. A lens-fitted photo film unit as defined in claim 4, wherein said linking mechanism includes a rear face of said end portion, said rear face is away from a front face of said charger switch when said changeover plate is in said first set position, and pushes said front face of said charger switch when said changeover plate is in said second set position. 6. A lens-fitted photo film unit as defined in claim 5, further comprising: a front cover for covering a front of said main body; an access opening, formed in said front cover, and disposed in front of said charger button portion; and an operation projection, formed to project from said charger button portion, operated externally through said access opening, for sliding of said changeover plate and for depression of said charger button portion. 7. A lens-fitted photo film unit as defined in claim 2, further comprising a large diameter opening, formed in said changeover plate, having a diameter larger than said diameter of said small diameter opening, and set at said exposure opening when said changeover plate is in said second set position. 8. A lens-fitted photo film unit as defined in claim 7, wherein said large diameter opening comprises an arc-shaped recess formed in one end of said changeover plate. 9. A lens-fitted photo film unit as defined in claim 2, wherein said photo film has speed from ISO 800 to ISO 3200, said exposure opening has an f-number from f/5.6 to f/8, and said small diameter opening has an f-number from f/13 to f/27. 10. A lens-fitted photo film unit as defined in claim 1, further comprising a charger member linearly slidable among first, second and third mode positions, wherein said aperture stop changer includes a changeover plate moveable to said first and second set positions, and wherein said charger member, when in said first mode position, turns off said charger switch, and when in said second mode position, turns on said charger switch and causes said linking mechanism to move said changeover plate to said first set position, and when in said third mode position, causes said linking mechanism to move said changeover plate to said second set position. 11. A lens-fitted photo film unit as defined in claim 10, wherein said linking mechanism includes: an end portion of said changeover plate; a spring for biasing said changeover plate to said first set position; a driving projection, formed to project from said charger member, disposed close to said end portion, wherein said driving projection, when said charger member is in said first and second mode positions, is moved away from said end portion, and when said charger member is in said third mode position, presses said end portion to move said changeover plate to said second set position. 12. A lens-fitted photo film unit as defined in claim 11, wherein said changeover plate is pivotally movable. 13. A lens-fitted photo film unit as defined in claim 10, wherein said flash unit has a circuit board; said charger switch includes first and second contact points disposed in a front of said circuit board; said charger member includes a contact segment for being away from at least one of said first and second contact points when in said first mode position, and for contacting said first and sec ond contact points simultaneously when in said second and third mode positions. 14. A lens-fitted photo film unit as defined in claim 12, wherein said second mode position is disposed between said first and third mode positions. 15. A lens-fitted photo film unit as defined in claim 14, wherein said charger member is slidable to said first, second and third positions. 16. 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. 17. 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, 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; 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. 18. A lens-fitted photo film unit as defined in claim 17, wherein said aperture stop changer includes: a changeover plate movable to said first and second set positions; and a small diameter opening, formed in said changeover plate, 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, and set away from said exposure opening when said changeover plate is in said second set position. 19. A lens-fitted photo film unit as defined in claim 18, wherein said second mode position is disposed between said first and third mode positions. 20. A lens-fitted photo film unit as defined in claim 18, wherein said linking mechanism includes: an end portion of said changeover plate; a spring for biasing said changeover plate to said first set position; a driving projection, formed to project from said charger member, disposed close t
