Description
The utility model relates to a kind of easy to operate, cheap, the colour enlarge-printing system that is easy to carry about with one, not influenced by environment for use in the field of taking pictures.
The colour enlarge-printing system that uses is used the halogen lamp as light source at present, adopts the colour cast of " additive color process " computer mixed light system compensation egative film; And by the density analysis systematic analysis egative film density of computer control; Control is enlarged and print the time shutter.Adopt the very high paper advance mechanism drive dish dress enlarged color photograph sensitive paper of precision to be the continuous paper supply of the photo of enlarging and print.Sensitive paper after the exposure of enlarging and print carries out continuous colour development and bleaching, photographic fixing processing with dark case washer, in flushing, in order to satisfy the requirement of developing technique, guarantee that the processing time of sensitive paper in soup contacts the degree of uniformity of soup with sensitive paper, the certain speed of tool in the time of will making sensitive paper enter soup, and keep constant speed in soup, to move, after the time of technological requirement finishes, the soup that speeds away changes drying and shearing over to.Therefore at present the colour enlarge-printing system that uses, volume is big, complex structure, manufacturing cost height, power consumption are big, and each operate as normal must be used more washing fluid, (each dosage is about tens of liters).So be not suitable for very much processing entity and individual's use of a small amount of photochrome, generally only can make center or bigger photographer's's internal fixation use, and environment for use is had relatively high expectations, and easily break down at photochrome with AC power.
The utility model purpose is, provides a kind of under the prerequisite that does not influence major function and technical indicator, can be at general room even the open-air miniature bright chamber colour enlarge-printing system that uses.
It adopts common flash lamp tube group flashing light as the exposure light source of enlarging and print, calculate the colour cast and the density of egative film with ball bearing made using, utilize light emitting diode to show its colour cast degree, and the exposure that control is enlarged and print according to the egative film density calculated, in proofreading and correct the egative film colour cast, with reference to the indication of light emitting diode group, adopt the manual correction of " subtractive color process " principle.Cutting out by certain specification in advance afterwards, and be contained in the photo of enlarging and print on the color photographic paper (hereinafter to be referred as holding the paper card sensitive paper) of " holding paper card " lining.Carry out colour development and blix processing for the sensitive paper utilization flushing machine at intermittence that has exposed.Compare with existing film processor, the utlity model has the characteristics of the following aspects:
1, adopts the exposure light source of a common flash lamp tube group flashing light, so can adopt low-voltage dc power supply (battery) power supply as sensitive paper.Because each luminous intensity and the colour temperature unanimity of flashlamp, so needn't consider voltage stabilizing when using AC power, beating of supply voltage generally can not influence the exposure quality of photo.
2, according to the color balance principle, utilize photoelectric technology to detect the relative colour cast of egative film automatically, calculate back (instructions Fig. 2) by simple and easy computing circuit, show egative film colour cast degree with three groups of light emitting diodes, this colour cast of the more explanation that the luminotron of inclined to one side certain look of expression is lighted is more serious, and the color correction sheet that can add corresponding density is by hand proofreaied and correct the egative film colour cast.
3, the utility model is provided with view screen, but observation post expands cutting out and the lens focus situation of egative film, and dry.
When plane mirror (9) was turned among the figure dotted line position, the light after then focusing on by camera lens (5) was reflected to display screen (8) and goes up imaging, observes the focusing situation for the user, the position of image, and the naked eyes of size and end colour cast degree are auxiliary to be differentiated.The colour cast of egative film is also detected to simple comparator circuit by sensor (6) and calculates, on colour cast indicator (7), reflect, but so the user both judge the colour cast degree of egative film in conjunction with (or only according to demonstration of colour cast indicator), the color correction sheet group (4) that can add suitable density is proofreaied and correct the egative film colour cast, guarantees the correct reduction of photo color.
Increase thereupon or reduce according to the enlargement ratio β of imaging formula (1/f=1/u+1/V) imaging when increasing or reducing image distance V, (β=V/u).Therefore, in present principles, only need to move the position of plane mirror (9) axle that can rotate around the axis, can change image-forming range, regulate the multiple of enlarging and print along the direction of arrow.
In the developing technique of photochrome, it generally is different that sensitive paper carries out the time that colour development and blix handle.In order to simplify the internal structure of an organization, present principles adopts the time segment standard that a set time handles as flushing, with colour display screen, float the reasonable quantity combination of deciding to insert in the medicine groove of holding the paper card sensitive paper after, satisfy in the developing technique colour display screen and float the different time requirement of deciding processing.
As adopt 30 seconds as the time segment standard, the time that requires colour display screen in the EP-2 technology is 3 minutes and 30 seconds, floating fixes time is 1 minute and 30 seconds, then can insert 7 in advance in the colour display screen groove and hold paper card, floats to decide to insert 3 in the groove and hold paper card.After the work beginning, extracted 1 head end of holding paper card sensitive paper insertion colour display screen groove that has exposed every 30 seconds.Simultaneously, extracting one from colour display screen groove tail end holds paper card and shifts out outside the groove.During from the work beginning, after hoisting frame lifts 7 times, just hold the paper card sensitive paper for first that can propose to insert the colour display screen groove, this is held the paper card sensitive paper and handled 7 times of 30 seconds just in development, promptly 3 minutes and 30 seconds, just in time satisfies technological requirement, be shifted into then to float and decide in the groove, in like manner float and decide to insert 3 in advance in the groove and hold paper card, thus hold floating of paper card sensitive paper decide the processing time be three 30 seconds, promptly 1 minute and 30 seconds.Because hoisting frame is lifting when holding the paper card sensitive paper, always after the tail end of medicine groove proposes one again the head end at this groove insert one, carry out colour display screen and float deciding processing so always can guarantee the paper card sensitive paper of holding of fixed qty in the medicine groove.
In " subtractive color process " mixed light, according to integration ash principle, three kinds of basic complementary color light (yellow of equal densities, magenta, cyan) mixing the back is grey, therefore in color correction, need only appropriate combination color correction sheet, make it to get final product for the colour cast combination back gray of egative film, in view of the above, in the inspection look, detect the content of three kinds of basic complementary color light in the mixed light respectively, testing result is pressed one group of (Huang～product in twos, product～green grass or young crops, Huang～green grass or young crops) compare calculating by the comparator circuit of forming by operational amplifier, utilize three groups to represent inclined to one side Huang respectively, pinkish red partially, blue or green partially light-emitting diode group shows the content of three kinds of basic complementary color light, owing to be that three coloured light compare in twos, so two groups of luminotron groups that colour cast is serious in showing show, another group does not show, luminous counting is many more, illustrate that this colour cast is serious more, in conjunction with the observation of display screen, the color correction sheet that adds corresponding density is proofreaied and correct again.
But the auxiliary colour cast degree of differentiating egative film of naked eyes is to guarantee the quality of enlarging and print of photochrome.
4, the egative film of being enlarged and print can arbitrarily be adjusted within the specific limits and expand the multiple of putting, and any partial picture of egative film that demonstration on screen is amplified.Picture shown on screen is in full accord with the picture scope and the size of the photo of enlarging and print out.
5, adopt the sensitive paper that the paper card clamping has been cut out of holding that can use repeatedly repeatedly, when the sensitive paper that flushing has exposed, the sensitive paper of holding paper card and clamping enters soup simultaneously.
6, colour display screen and float the volume of deciding the medicine groove to hold paper card bigger so use soup seldom to get final product work, can replenish fresh liquor according to the consumption situation, at work automatically to keep the work vigor of two kinds of soups in the soup.
7, in whole flushing process, only adopt one regular time section as time standard, and the colour display screen that developing technique requires and float the interval of fixing time is by the quantity decision of holding paper card in the two medicine grooves.
6, hold paper card feeding machine, the egative film density analysis, control is automatically all adopted in the adjustings of the light exposure control of enlarging and print and fluid temperature etc.
