Abstract

A multifunction shift-focusing camera comprises a front element, a flexible cavity, a back element and an adjusting track. The multifunction shift-focusing camera relates to a photographic device which can adjust the angle between the optical axis of lens and the film plane. The purpose is to provide a portable camera with shift-focusing, which can not noly shoot with conventional lens and films, but randomly control the perspective relation and depth effect of imaging. Besides, it can use 4*5 large frame negative films by changing the back element. The characteristic is that it has a wrigglable flexible cavity. The front element can install ordinary leaf shutter lens and the back element can be changed to use the 120 negative films and 4*5 large frame negative films of various specifications. Since adopting the above mentioned scheme, the camera can control the perspective and depth of imaging by shift-focusing when taking pictures. Besides, it can use the 120 negative films and 4*5 large frame negative films of various specifications by changing the back element. Moreover, the structure become exceptionally simple for the use of the flexible cavity.

Description

The multi-functional camera shaft that moves

Technical field

The utility model relates to the camera of angle between adjustable effect camera lens optical axis and film plane, is specially the multi-functional camera shaft that moves.

Background technology

In the ordinary course of things, the fuselage of common 120 cameras is used for connecting camera lens and back film loader, and its structure is that accent that fix, stiff is imitated, can only disassembling, assembling and replacing camera lens and back film loader, and the focusing function that the adjustment of camera lens only moves forward and backward.That is to say that the camera lens optical axis of general camera can not carry out the arbitrarily angled mobile axle that moves with respect to fuselage and transfer effect, the perspective relation and the Deep Canvas of its imaging on egative film can not arbitrarily be controlled.This function only could realize on large-scale 4 * 5 professional bases.And large-scale 4 * 5 professional bases is bulky, carries extremely inconvenient.

Summary of the invention

Goal of the invention:

The purpose of this utility model provide a kind of move axle the portable camera fuselage, it can not only use conventional camera lens and film to take, and can arbitrarily control the perspective relation and the Deep Canvas of imaging.By changing the back group, also can take 4 * 5 big picture egative films.

The technical scheme of technical solution problem:

The purpose of this utility model is achieved in that the front end of this fuselage is preceding group, and a front clamp seat is arranged, and lens mounts is arranged on the front clamp seat, and lens mounts is used for the common between-lens shutter camera lens of adapted, and front clamp seat is provided with the shutter flip flop equipment.The rear end of this fuselage is a back group, have one after deck, back deck can be used alternatingly the slide viewer of focusing and focus and use the back film loader to take.The back group can be used 120 back film loaders of all size by changing the film loader adaptor; And change back group of big egative film, can also take 4 * 5 big picture egative films.The cavity that a scalable twisting is arranged in the centre of preceding group and back group, this telescopic cavity can make camera lens optical axis transfer and imitate with respect to the axle that moves that the film plane on the group of back carries out arbitrarily angled control.Before group and back group be mounted on the adjustable track, there is the removable and locking of gear at the movable position on adjustable track and the front and back deck.The focusing slide viewer is installed earlier during use, by adjusting each movable position, is carried out composition, focus, move axle and transfer operations such as effects, lock then, change the focusing slide viewer, get final product normal photographing with film loader.

Beneficial effect:

Owing to adopting such scheme, this fuselage can transfer effect imaging to be had an X-rayed and depth of field control by moving axle when taking, and replaceable back group, uses 120 films and 4 * 5 big picture egative films of different size.And the use of telescopic cavity also makes its structure become simple unusually.

Description of drawings

Sectional structure chart when Fig. 1 is to use 120 film loaders

Fig. 2 is the sectional structure chart when changing the back group and using 4 * 5 big picture egative films

Among the figure 1, lens mounts, 2, front clamp seat, 3, telescopic cavity, 4, the back deck, 5, the film loader adaptor, 6, preceding group of activity regulate the position, 7, back group activity regulates the position, 8, adjustable track, 9, the tripod fixed bit.

Embodiment

Below in conjunction with the description of drawings specific embodiments:

The multi-functional camera shaft that moves is made up of preceding group, telescopic cavity (3), back group, adjustable track (8), and it contains a telescopic cavity that can twist (3).Preceding group can be installed common between-lens shutter camera lens, and the back group is replaceable, so that use 120 egative films and 4 * 5 big picture egative films of all size.

In the embodiment shown in the figures, (1) (2) (6) are preceding group, and lens mounts can be installed the between-lens shutter camera lens on (1), and join with front clamp seat (2).Link a telescopic cavity (3) between front clamp seat (2) and the back deck (4).(4) (5) (7) are the back group, and a film loader adaptor (5) is arranged on the back deck (4), can be used alternatingly focusing slide viewer and film loader.Elder generation goes up at back deck (4) slide viewer of focusing is installed during shooting, and position (6) is regulated in preceding group activity and composition is carried out in back group activity adjusting (7) by adjusting, focus, move axle transfers operations such as effect, and each activity adjusting position of locking is changed film loader and can be taken after finishing.Sectional structure chart when accompanying drawing 2 is to use 4 * 5 big picture egative films needs to change back group and taper telescopic cavity (3).

Claims

1. the multi-functional camera shaft that moves is made up of preceding group, telescopic cavity, back group, adjustable track, it is characterized in that: contain a telescopic cavity that can twist.

2. the multi-functional camera shaft that moves according to claim 1 is characterized in that: preceding group common between-lens shutter camera lens can be installed, the back group is replaceable, so that use 120 egative films and 4 * 5 big picture egative films of all size.
