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 reversible type camera

The utility model relates to a kind of reversible type 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.

The purpose of this utility model is: design a kind of reversible type camera and make it in shooting process conversion light reaching the film face size arbitrarily, to satisfy user's requirement.

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, the shift key that has the cropping viewfinder is enclosed within on the shift fork that meshes together with conversion sheet, by the control transformation key button, can finish the conversion of panorama and cropping film.

Adopt this converting system on the camera, greatly facilitate shutterbugs, people can take out the egative film of different size, the i.e. egative film of cropping and any conversion of panorama at same volume film arsis, particularly this converting system is simple in structure, easy to use, particularly can use on simple and easy camera.

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 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).

Transition components is packed into behind the camera, as shown in Figure 4, cropping viewfinder (7) is positioned at the bottom of viewfinder (12), shift key (6) combines as a whole with cropping viewfinder (7), groove (15) is inserted on the conversion shift fork (11), conversion key button (14) is in as shown in Figure 1 position, there is spacing preiection (16) groove (15) outside, when changing key button (14) in I shown in Figure 1 or II position, spacing preiection (16) matches with the limited impression (17) of camera, 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, the 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, a kind of reversible type camera, it is characterized in that: the shift key of band cropping viewfinder, insert in the finger by groove on it, have on the finger on the blade double wedge that double wedge is engaged in conversion sheet, the blade of its conversion sheet have a finger, extension spring is enclosed within on the projection of two blades, and the two ends of two conversion sheet have projection respectively.

2, reversible type camera according to claim 1 is characterized in that: the projection of conversion sheet inserts in the camera movingly, and there is the spacing preiection that matches with camera upper limit groove the groove outside.
