Description

Color and monochrome photograph integrated enlarger

The utility model relates to a kind of photo enlarging and printing device, particularly a kind of colour enlarger that has the three primary colors light source.

Chinese patent CN87204968U discloses a kind of " additive color process quality color enlarger ", adopt three incandescent light source through red, green, the primary colors color filter film obtains three primary colors, in the mixed light chamber, be superimposed as desired coloured light simultaneously and make the printing paper exposure, be equipped with a plurality of color filter group with traditional by a light source, and compare with the colour enlarger that the time shutter of every kind of coloured light is successively regulated in mechanical catanator gradation, though have simple in structure, easy to operate advantage, but also the same with other various forms of colour enlargers, all only can carry out enlarging and print of photochrome and can not take into account enlarging and print of black-film photo.

The purpose of this utility model provides a kind of photochrome of can enlarging and print, the integrated photo enlarger of colour, black and white of the black-and-white photograph of also can enlarging and print.

Realize that the integrated photo enlarger of colour, black and white of the purpose of this utility model mainly is made up of support, exposure lamp box, mixed light chamber, lens assembly, stretching leather bellow and phase mechanism of paper, the exposure lamp box has the Red Green Blue color filter film before at least three illuminators, the reflecting plate that can twitch and three are separately positioned on three illuminators, has at least one to be arranged on the reflecting plate that can twitch and can to leave the light source session with the twitch of reflecting plate in described three primary color filter eyeglasses.When carrying out photochrome when enlarging and print, the light beam of three illuminators becomes primaries by red, green, blue three color filter films respectively, mixing in the mixed light chamber below reflecting plate is projeced into lamp house, see through color negative film, project on the printing paper through camera lens, make the printing paper exposure, finish the exposure program of photochrome; When carrying out the enlarging and print of black-and-white photograph, twitch reflecting plate until the session scope that makes before the primary color filter eyeglass that is arranged on the reflecting plate leaves the former illuminator that is positioned fully, close two other illuminator simultaneously, the white light of this illuminator is directly projected in the chamber, mixed light chamber through black and white negative film, camera lens projects on the printing paper, finishes the exposure program of black-and-white photograph; The printing paper mechanism design is become with support to be separable socket connection mode, the printing paper of sensitization can be taken off and give conventional flushing, finish expansion, the seal of whole photo.

Also can be in lamp box uniform four illuminators, only color filter film is set in the front of three illuminators, by controlling the illuminator that is equipped with color filter film before its three and another is not anti-phase interlocking between the white light source lamp with color filter film, be the white light source lamp when bright other three lamps for closing shape, otherwise, when the illuminator of three band color filter films is bright, the white light source lamp is for closing shape, thereby when realizing carrying out enlarged color photograph, the illuminator of three band color filter films is bright, and required primaries is provided; Carry out black-and-white photograph when enlarging and print, only the white light source lamp is bright, for black and white negative film provides white light.

With of the form setting of three primary colors eyeglass, it can be changed as required at any time, as changing needed other look color filter film in the subtractive color process color correction mode into, with the function of further this film processor of expansion with plug-in mounting.

The utility model is simple in structure, making is easy, and is easy to operate, and applicability is strong; The exposure that not only can adopt two kinds of color correction modes of additive color process and subtractive color process to finish photochrome is printed, also can realize enlarging and print of black-and-white photograph, both can reduce the input of equipment, also improve usage ratio of equipment, be particularly suitable for that the general density of population is little, the undersaturated middle-size and small-size photo studio of workload uses.

Below in conjunction with embodiment and accompanying drawing the utility model is described further.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of exposure lamp box

As shown in Figure 1, the utility model is made up of support 1, exposure lamp box 2, mixed light chamber 3, lens group 4, stretching leather bellow 5 and phase mechanism of paper 6.Be connected with detachable syndeton between its phase mechanism of paper 6 and the support 1, what adopt in the present embodiment is common socket connection, conveniently to assign the sheet clamping plate, realizes that simple monolithic enlarges and print; Grafting paper feed machine can carry out batch again and enlarge and print; Lens assembly, stretching leather bellow and exposure lamp box all can be continued to use existing variety of way setting and be installed on the support.The formation of exposure lamp box 2 comprise in the present embodiment three be distributed in the case and with at grade incandescent lamp 7,8 of place, mixed light chamber, 9(referring to Fig. 2) three pieces place 10,11,12 and ends of color filter film three lamp the place aheads, that be respectively red, green, blue three looks to stretch the reflecting plate of twitching 14 outside casing respectively, wherein, incandescent lamp 7 be arranged on mixed light chamber 3 directly over, reflecting plate is flat between them, color filter 10 is fixed on the reflecting plate, and color filter 11,12 is plugged on incandescent lamp 8,9 the place aheads.During work, by the enlarged color photograph key 16 on the operating operation platform, make three lamps order by red, green, blue three monochromatic exposure color corrections, each monochromatic light sees through color negative film 17 through the mixed light chamber, on camera lens projects sensitization printing paper in the phase mechanism of paper of stretching leather bellow lower end.When enlarging and print black-and-white photograph, reflecting plate is extracted out, the former color filter 10 that blocks before incandescent lamp 7 is also extracted out thereupon, the operation black and white key 18 of enlarging and print, only make incandescent lamp 7 bright opening and the preceding incandescent lamp 8,9 that is equipped with color filter film does not work, only provide promptly that white light sees through black and white negative film through the mixed light chamber, camera lens projects on the sensitization printing paper.

Claims (2)

1, a kind of colour, the integrated photo enlarger of black and white, comprise support, exposure lamp box, mixed light chamber, lens assembly, stretching leather bellow and phase mechanism of paper, it is characterized in that described exposure lamp case comprises at least three illuminators, reflecting plate and three are separately positioned on the color filter film that is respectively the red, green, blue look before three illuminators, described reflecting plate is the reflecting plate that can twitch, has at least a described color filter film to be arranged on the reflecting plate and also can leave the light source session with the twitch of reflecting plate.
