Description
A kind of flash type disposable camera that is used to photograph relates to photographic equipment.
The disposable camera of Chu Xianing also claims the auto heterodyne film in recent years, has two types: a kind of is not to be with flashlamp, is only applicable to outdoor, photography on daytime; A kind of is to be with flashlamp, is applicable to the photography in indoor and outdoor, daytime and evening.But all abroad disposable cameras all adopt ISO400/27 ° film, if adopt ISO100/21 ° film, then can cause serious owing to expose to the sun, make photo picture gloomy, particularly for the disposable camera of being with flashlamp, because its relative aperture is little, and can't in suitable distance, obtain the strobo photography effect of requirement.For example when aperture is F10, in guide number is under the condition of GN10, the best theoretical that its flash of light is taken only is 1m, and the aperture of disposable camera is generally all more than F11, the GN value of compact flash lamp is many below 10, so theoretical shooting distance is just nearer, obviously is the needs that can not satisfy actual photographed far away.Abroad be to adopt from the light sensitivity that improves film promptly to adopt the approach of ISO400/27 ° of film to solve the problems referred to above.But 27 ° of films belong to professional film, and price is expensive, and developed grain is thick, and domestic production is few, and quality do not pass a test, and therefore, use face and popularization face are narrow.
It is a kind of simple in structure and be suitable for the disposable camera that indoor and outdoor is used that goal of the invention of the present utility model is to provide.
The utility model can adopt following technical proposals to reach goal of the invention.
The utility model is by fuselage (1), magazine (2), shutter box (3), camera lens (4), front shell cover (5), rear shell cover (6), flash lamp component (7), winding mechanism (8) and film (17) are formed, wherein, camera lens (4) is a triplet lens, this camera lens is made up of three lens, anter is positive meniscus shaped lens (9), middle sheet is biconcave lens (10), rear panel is biconvex lens (11), before the positive meniscus shaped lens (9), it is protruding that the back is respectively, concave spherical surface, its radius of curvature R 1, R2 is respectively (9.00mm-9.5mm), (14.30mm-15.00mm), before the biconcave lens (10), the back is concave spherical surface, its radius of curvature R 3, R4 is respectively (25.00mm-25.50mm), (9.00mm-9.50mm), before the biconvex lens (11), the back is protruding sphere, its radius of curvature R 5, R6 is respectively (14.10mm-14.80mm), (16.20mm-16.80mm), film (17) is an ISO100/21 ° of film, shooting effect when using flashlamp for improving, the utility model is provided with movable light hurdle sheet (12) in the back of camera lens (4), being provided with greatly of light hurdle sheet (12) with the corresponding part of camera lens (4), little different hole, light hurdle sheet (12) links to each other with the four-bar mechanism that can make its move left and right, and this four-bar mechanism is by coupled switch (15), connecting rod (13) and (14) and protecgulum shell are formed.
Compared with prior art, the utlity model has following advantage:
(1) because the utility model uses ISO100/21 ° of film, ISO400/27 ° of film in the flash type disposable camera that uses is cheap now, so of the present utility model with low cost.
(2) owing to be provided with movable light hurdle sheet in the utility model, aperture of the present utility model can be changed according to taking needs, thereby, can improve the utility model shooting quality, be more suitable for use in indoor and outdoor.
(3) the utility model is controlled the variation that moving of light hurdle sheet promptly controlled aperture by four-bar mechanism, and it is simple in structure, the reliability height.
(4) because the utility model adopts triplet lens (wherein a slice is the lens of different medium), make its various aberrations of integrated calibration preferably,, have good advantage mutually of fine quality so compare with existing disposable camera monolithic camera lens of the same type.

With reference to the accompanying drawings embodiment of the present utility model being done one describes in detail:
The utility model is by fuselage (1), magazine (2), shutter box (3), camera lens (4), front shell cover (5), rear shell cover (6), flash lamp component (7), winding mechanism (8) and film (17) are formed, wherein, film (17) adopts ISO100/21 °, camera lens (4) is a triplet lens, this camera lens is made up of three lens, anter is positive meniscus shaped lens (9), middle sheet is biconcave lens (10), rear panel is biconvex lens (11), anter can be formed by glass or plastic production, middle sheet and rear panel are formed by plastic production, before the positive meniscus shaped lens (9), it is protruding that the back is respectively, concave spherical surface, its radius of curvature R 1, R2 can be respectively at (9.00mm-9.50mm), (14.30mm-15.00mm) select in the scope, before the biconcave lens (10), the back is concave spherical surface, its radius of curvature R 3, R4 can be respectively at (25.00mm-25.50mm), (9.00mm-9.50mm) select in the scope, before the biconvex lens (11), the back is protruding sphere, its radius of curvature R 5, R6 can be at (14.10mm-14.80mm), select in the scope (16.20mm-16.80mm), in the present embodiment, can select optimum lens, its parameter is: preceding, before the middle rear panel lens, radius-of-curvature (the R1 of back, R2, R3, R4, R5, R6) be followed successively by 9.15mm, 14.70mm, 25.17mm, 9.15mm, 14.44mm reach 16.53mm, remaining parts all can adopt and the disposable camera member roughly the same that uses now.For improving the shooting effect of the utility model when using flashlamp, the utility model is provided with movable light hurdle sheet (12) in the back of camera lens (4), be provided with large and small different hole at light hurdle sheet (12) with the corresponding part of camera lens (4), light hurdle sheet (12) links to each other with the four-bar mechanism that can make its move left and right, and this four-bar mechanism is made up of coupled switch (15), connecting rod (13) and (14) and protecgulum shell.When people when gloomy occasion is taken, only need stir coupled switch (15) with the flashlamp interlock, just can drive light hurdle sheet (12) by four-bar mechanism this moment, aperture of the present utility model changed, thereby more help using the shooting effect of flashlamp.
