Abstract

The utility model relates to a convertible camera. The utility model is provided with a convertible system which causes a panorama photographic film and a cropping photographic film of the camera can be converted arbitrarily during shooting and causes viewing and light-sensitive surface can be adjusted synchronously. A conversion key with a cropping viewing window is sheathed on a shifting fork which is engaged with a conversion tablet. The conversion of panorama and a cropping film can be completed through the control of a conversion key button. The camera which adopts the conversion system is convenient for a lover. The conversion system has the advantages of simple structure and easy use, and especially can be used in a simple camera.

Description

The disjunctor conversion equipment that uses on the camera

The utility model relates to the disjunctor conversion equipment that uses on a kind of camera.

Camera in the prior art, its light reaching the film face generally all is light reaching the film faces that a kind of camera adopts a kind of size, the size of light reaching the film face is changeless in shooting, these cameras because of its can not be in shooting process the size of conversion light reaching the film face arbitrarily, use and picture choice to photographer are restricted, and can not satisfy the requirement of people to various shootings.And some can change the camera of light reaching the film face size on same film, and also because of its throw-over gear complexity, parts are many, and fragile.

The purpose of this utility model is: design use on a kind of camera can with the one that control light-sensitive surface synchro control the is found a view conversion equipment of finding a view, make it simple in structure, not fragile, to satisfy people's requirement of conversion light-sensitive surface size arbitrarily in shooting process.

The utility model adopts following structure to realize above-mentioned purpose: design a kind of converting system, can make camera panorama sensitive film and any conversion of cropping sensitive film in shooting, and make and find a view and light-sensitive surface is adjusted synchronously, wherein the one conversion equipment of finding a view is that the cropping viewfinder is made as an one-piece construction, and directly and shift key be connected as a single entity, also be provided with spacing preiection on the shift key, to guarantee that the conversion bond energy accurately is placed on required position, have groove on the shift key, groove is enclosed within on the shift fork, shift fork connects the cropping structure of The whole control sensitive volume, so that the cropping viewfinder can be synchronized with the movement with the conversion sheet of sense of control mating plate cropping, to guarantee finding a view and the sensitive film panorama synchronous conversion of cropping.

Adopt this converting system on the camera, greatly facilitate shutterbugs, people can take out the egative film of different size at same volume film arsis, be the egative film of cropping and any conversion of panorama, particularly this converting system is simple in structure, easy to use, because the cropping viewfinder is an one-piece construction, and directly and shift key be connected as a single entity, reduced accident rate, increased the service life, particularly on simple and easy camera, used more convenient.

Illustrate below in conjunction with example:

Camera front view when Fig. 1 is cropping.

Camera was opened the rear view of bonnet when Fig. 2 was cropping.

The decomposing schematic representation of Fig. 3 transition components.

Synoptic diagram when Fig. 4 opens protecgulum.

Cropping synoptic diagram when Fig. 5 opens protecgulum.

Transition components is as shown in Figure 3 packed into behind the camera, finishes by shift key (6) that cropping is taken pictures or common panorama is taken pictures.

Transition components comprises controlling finds a view and sensitization two parts, is made up of cropping viewfinder (7), shift key (6), conversion shift fork (11), conversion sheet (8A), conversion sheet (8B), finger (91), extension spring (10) respectively.

Transition components is packed into behind the camera, as shown in Figure 3, the control picture of finding a view is made up of find a view viewfinder (7), shift key (6), conversion key button (14), positioning convex (16), groove (15), the limited block (22) of structure of one conversion, be an one-piece construction, as shown in Figure 4, cropping viewfinder (7) is positioned at the bottom of viewfinder (12), and groove (15) is inserted on the conversion shift fork (11), limited block (22) is arranged, with the displacement of restriction conversion shift fork (11) in groove (15) in the groove.Conversion key button (14) is in as shown in Figure 1 position, there is spacing preiection (16) groove (15) outside in order to guarantee that spacing preiection (16) can be under the control of conversion key button (14), can move to respectively in two grooves (17) of camera, spacing preiection (16) should have certain elasticity.

When changing key button (14) in I shown in Figure 1 or II position, spacing preiection (16) matches with two detents (17) of camera respectively, any displacement with restriction conversion key button (14), double wedge (9) on the shift fork (11) inserts on the tooth of leaf fan (18A), locate by screw (19) at last, the two ends of extension spring (10) are connected in two flabellums (18A) respectively, on the projection (18B) (20), so that conversion sheet (8A) conversion sheet (8B) resets, finger (91) on the blade (18A) is stirred blade (18B) motion, and conversion sheet (8A) and conversion sheet (8B) are inserted in the camera movingly by projection (21).

The cropping viewfinder window is in viewfinder object lens (1) front, and (2) are the viewfinder eyepiece, and (5) are mirror before the camera, and (3) are mirror behind the camera, and (4) quilling wheel (13) is a lens mount.

Claims

1, the conversion equipment that uses on a kind of camera, find a view and change the light-sensitive surface two-part structure and form by conversion, it is characterized in that: the one conversion structure of finding a view is: the cropping viewfinder is an one-piece construction, and viewfinder and shift key are connected as a single entity, groove on the shift key directly inserts in the finger of sense of control photo structure, positioning convex is arranged on the shift key, limited block is arranged in the groove.

2, the conversion equipment that uses on the camera according to claim 1 is characterized in that: the projection of the conversion sheet of sense of control light quantity inserts in the camera movingly, and two detents that cooperate with positioning convex are arranged on the camera.
