Abstract
The utility model discloses a novel multifunction enlarger, comprising an enlarging lens, a focusing structure, emblazon film, a dark box which can make the film move, a shutter which can control the exposure time, etc. The utility model not only has enlarge function but also can enlarge, reduce, copy with original size and near distance photograph under the condition of strong and weak light rays. The utility model has the advantages of simple structure, convenient operation and convenient portability.
Description
The utility model is to belong to amplification, camera technique field.
Existing various enlarger because of having only enlarging function, if need carry out reproduction and close-up photography, must be equipped with various device and annex, thus feel inconvenience in use, furthermore these equipment and annex are the comparison costlinesses.At present, though some carries out improved technology and product to original enlarger, yet, on the function that realizes the enlarger a tractor serves several purposes, developed as yet.
The purpose of this utility model just provides a kind of novel, multi-functional enlarger, and it can not only amplify, and can carry out reproduction and close-up photography in indoor and outdoor, and this multi-functional enlarger did not at home and abroad occur as yet.
Solution of the present utility model: be exactly enlarging lens and the focusing structure that utilizes the former machine of enlarger, agree without prior consultation part and the shutter section of control time shutter that increase the splendid attire film again and can make that film walks about wait and form multi-functional enlarger.And shutter and enlarging lens linked together.Because the enlarging lens of enlarger is to use in closely amplifying and dwindle, and the focusing structure of enlarger is when carrying out reproduction and close-up photography, but the bright dark degree of light accurate focusing how all no matter.Therefore, use the enlarging lens of enlarger and focusing structure carries out reproduction and close-up photography is fully feasible.
It is identical with the operating process of common enlarger that the utility model is used for realizing amplifying this function operations process.When being used for realizing reproduction and close-up photography, regulating the body adjustment structure makes alignment lens take thing, adopt two kinds of methods to carry out accurate focusing according to the bright dark degree of light, then egative film is put into agreeing without prior consultation of special cast molding, and will agree the film holder position of putting into enlarger without prior consultation, and draw back the following pumping board that agrees without prior consultation, regulate film, control shutter with the shutter line at last, thereby carry out reproduction and close-up photography.
Body adjustment structure of the present utility model and tripod adapted, can change its direction and position flexibly, easily, the utility model can not only amplify, also can be under the bright or dark situation of light, amplify or dwindle or keep size constant, the reproduction of clear image and close-up photography.Multi-functional enlarger features simple structure, easy to operate, and be easy to carry.
Accompanying drawing 1 is the structural representation of multi-functional enlarger.
Accompanying drawing 2 is splendid attire films and can makes the structural drawing that agrees without prior consultation that film walks about.
Accompanying drawing 3 is shutter structure figure of control time shutter.
Embodiment of the present utility model is according to accompanying drawing 1, accompanying drawing 2, and accompanying drawing 3 is illustrated.
Have on tripod leg (7) by body VTOL (vertical take off and landing) support bar (1), pitching knob (3), body lifting knob (4), body support slipper (5), elastic equilibrium clockwork spring and close the body adjustment structure of (6) forming, it can change the position and the direction of multi-functional enlarger flexibly, easily.The multi-functional enlarger host machine part that is connected with the body adjustment structure comprises lamp house (8), spotlight (9), film holder (10).Stretching leather bellow (12), enlarging lens (13), focusing knob (2) and by last pumping board part (18), (19) agree upper cover part (20) without prior consultation, agree main part (21) without prior consultation, knob portion (22).Agree the splendid attire film that following pumping board part (23) forms without prior consultation and can make agree without prior consultation (11) that film walks about, and the shutter of forming by shutter main body (24) and cable release (17) (16).The outer silk of standard (M39 * 1) (26) that can be connected with enlarger is arranged at shutter main body top, the internal thread (M39 * 1) (28) that can be connected with enlarging lens is arranged at the shutter main body bottom, and the shutter main body middle part has the line that is connected with cable release (17) to revolve seat (25) and blade (27).The thickness of whole shutter is (live part that refers to the middle part) about 5mm, and its bore substantially exceeds the diameter of lens wearer.Shutter (16) and enlarging lens (13) connect and are contained on the multi-functional enlarger.
When the utility model amplified, its operating process was identical with the operating process of common enlarger.
When the utility model carried out reproduction and close-up photography, at first the pitching knob (3) of the body governor motion of adjusting and tripod adapted and body lifting knob (4) etc. changed the position and the direction of multi-functional enlarger, aimed at and took thing.Focus then.If under the bright situation of light (as outdoor), its focus adjustment method is to take off lamp house, in film holder (10), put a fritter drawing, together put into multi-functional enlarger again, the frosted imaging screen that forms is carried out accurate focusing.If under the dark situation of light (as indoor), its focus adjustment method is to put into egative film in film holder, by lamp house (8) polishing, make image be presented on that desktop (15) is gone up or easel (14) on, thereby carry out accurate focusing.After the rotation accurate focusing by focusing knob (2), take out film holder (10), put into the shooting of splendid attire film and agree (11) without prior consultation.The knob (22) of (11) is agreed in rotation without prior consultation, observe by the aperture on the last pumping board (18) that agrees (11) without prior consultation, aim at the position of film, at last, the following pumping board (23) of (11) is agreed in extraction without prior consultation, control is connected time shutter of the shutter (16) on the enlarging lens (13) with shutter line (17), amplifies or dwindles, or keep the reproduction and the close-up photography of original size.
