Description
The utility model relates to a kind of exposure structure of film processor, is the exposure structure of a kind of automatic location color filter specifically.
The exposure structure of general film processor mainly is the lamp source of penetrating in the lamp that establish the top of camera bellows, makes this lamp source see through the filter disc of different colors and exposes to the sun via camera lens and to be printed on the printing paper.The structure of this kind exposure when the setting of positioning time of color filter, is with artificial adjustment, and not only operation is difficult for, and needs the positioning time of each egative film of memory, therefore, is easier to cause the seal that exposes to the sun bad, influences the quality of photograph.
The purpose of this utility model is to provide a kind of automatic exposure structure of film processor, the filter disc of different colours is rotated by a motor driven, and make it to reach automatically the positioning time of remembering each egative film, thus solve the problem of hand formula operation, make film processor reach automatic exposure;
Another purpose of the present utility model is to provide a kind of automatic exposure structure of film processor, makes it to reach the location of color filter, for the seal that exposes to the sun of different colours;
Three of the purpose of this utility model is to provide a kind of automatic exposure structure of film processor, makes be controlled by computer the positioning time of egative film, reaches the effect that memory is set, thereby further simplifies the operation.
The purpose of this utility model is achieved in that a kind of automatic exposure structure of film processor, mainly includes an airtight casing and a projection box of being located on the board, is provided with light fixture in the casing, and the bottom of the below board of projection box is provided with camera lens; It is characterized in that described have be provided with a bolster in the casing, described light fixture is located in the bolster, also be provided with a motor in this bolster, the center of motor is connected to a rotating disk, and be provided with projection at interval in the periphery of this rotating disk, the surface of rotating disk is provided with circular hole, is pasted with the color filter of different colours on it, and the place ahead of bolster is provided with a shading element and a proximity switch; The projection box that the place ahead of bolster is provided with, the top of this projection box takes the form of inclined plane, and is provided with an open-work in vertical plane, inner edge one deck natural pearls plate that then has been sticked of projection box; Below bolster and projection box, be provided with a slide rail, the track of slide rail is provided with one and has the slide plate of open-work, and is provided with the anchor clamps of the clamping egative film of symmetry in the slide plate top.
The purpose of this utility model also can realize that the output terminal of described optical element and proximity switch is connected in a microcomputer host by following measure.
Principle of work of the present utility model and effect are, above board, be provided with a seal case and a projection box, be provided with a light fixture and motor in the casing, the center of motor is hubbed at the rotating disk of casing front end, rotating disk is provided with the circular hole of the color filter attaching of different colours, when horse when driving it and rotate, on the printing paper of the web-like that is able to light source to be printed on board inside to be exposed to the sun by camera lens with the image of egative film via color filter, projection box by light fixture.To solve manual problem; The signal of the location detecting of the projection shading light element of rotating disk reaches microcomputer host, remembers setting by host computer, and then simplifies the operation.
During other dial rotation, constitute the location of each color filter, to realize the exposure of different colours.
The explanation of accompanying drawing drawing:
Fig. 1 stereo appearance figure of the present utility model;
Fig. 2 three-dimensional exploded view of the present utility model;
Fig. 3 the utility model assembled sectional view;
The synoptic diagram of Fig. 4 the utility model turntable location action.
It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;
Please join illustrated in figures 1 and 2, the utility model mainly is provided with a board 1, be provided with a seal box 10 in the top of board 1, in this casing 10, be provided with a bolster 2, in bolster 2, be provided with a light fixture 21, an and motor 22, the axle center 221 of this motor 22 is connected in a rotating disk 23, and drive the rotation of this rotating disk 23, periphery at this rotating disk 23 is provided with projection 231 at interval, its surface then is provided with most circular holes 232, be pasted with the sheet 24 of different colours on this circular hole 232, and the place ahead of bolster 2 is provided with a shading element 25 and proximity switch 26, make motor 22 when driving rotating disk 23, cover this optical element 25 by projection 231, and constitute the location of each color filter 24, and remembered setting by a microcomputer host 20 positioning time.
The below of casing 10 is provided with slide rail 3, be provided with a slide plate 31 with open-work 311 in slide rail 3, and be provided with the anchor clamps 32,33 of symmetry in slide plate 31 tops, for clamping egative film 4, so, when light fixture 21 projection sources, be able to through heat shield 211, and different colours filter disc 24, via the projection box 27 in bolster 2 the place aheads, see through the camera lens 5 of board 1 bottom surface, invest the web-like printing paper 6 of board 1 inside; The projection image of egative film 4 exposed to the sun be printed on printing paper 6.
