Description

Structure for arbitrary removing shot film from camera

The utility model relates to and a kind ofly is assembled in modern camera and can makes sensitive film (hereinafter to be referred as film) take pictures part arbitrarily by the new structure that takes out in the camera.

Along with scientific-technical progress, modern camera has all reached higher level at every aspect of performance, society's owning amount is increasing, but present its sensitive film of the camera of producing must be put in order the volume film and all clap and could take out from camera, because of often being difficult to the short time, all clapped by a film, make the cameraman can not in time see photographic effects, this brings very big inconvenience for most specialties and amateur photographer, thus the bigger availability that limits camera.The film of bat that though some Professional Photography persons adopt darkroom technology also can take out from camera to be badly in need of, to get the sheet difficulty big because of it, requires highly, and the waste film is difficult for being accepted by numerous cameramans.

The purpose of this utility model provides a kind of cameraman of making can easily take out the film of having taken pictures as required from camera new structure camera.

For achieving the above object.Solution of the present utility model is to do following two on known sensitive film fast-assembling function photographic machine (as the Qingdao six types etc.) basis and improve design greatly having.One, a fan fuselage bonnet that will have camera now changes two fans into, and shading and protection that its bonnet A is used for not clapping film cassette chamber and camera lens etc. are at the new clothes sensitive film with take out whole this bonnets of opening when having clapped film.Camera back B be used for taking pictures the shading and the protection of film cassette.When having clapped film, taking-up opens this bonnet.Two fan bonnets open and close and are independent of each other.Two, at the back side of camera, camera lens is established a part device with the joint portion of clapping the film cassette chamber, the part device mainly by blade, blade operating key, blade cross cutter seam, film is formed by parts such as groove cover plates by groove, film, handle blade when needing and can cross the film cut-out of cutter seam and film has been taken pictures partly and do not take pictures the part disconnection being arranged in blade.

It is as follows to have the camera using method that this camera clapped film arbitrary removing structure (hereinafter to be referred as this structure): when newly loading, opening fuselage bonnet A will not clap film cassette and pack into and do not clap the film cassette chamber, extract suitably long film out, the film head is inserted film film perforation and camera octadentate wheel are combined by groove a little (about 10 millimeter) again, the fuselage bonnet A that closes can take pictures by known manner.All do not clapped as film, need to clap the film part by taking out in the camera, its taking-up program is, the manipulation blade will be arranged in film and cross the cut-out of cutter seam by the film of groove from blade, and camera is put into known camera bag, open camera body bonnet B, extract from clapping the film cassette that to have clapped film tight with the shading paper bag out, camera is taken out from camera bag, and the fuselage bonnet B that closes, camera are that the available not bat film of staying in the camera continues to take pictures.All clapped as film and to have adopted known camera reviewing mode will all clap film to return and do not clap film cassette, open fuselage bonnet A and can take out whole films.

Have the every volume sensitive film of the camera of this structure and take out and clapped the film number of times and do not limit, get leaf length at every turn and do not limit.Camera with this structure must have known sensitive film fast-assembling function simultaneously.

Owing to adopt above-mentioned organization plan, modern camera is being kept on original every function basis, increased newly and made the cameraman clap film by the function of taking out in the camera with what be badly in need of at any time, can satisfy more generally needs of one of cameraman, bigger raising the availability of existing camera.This is simple in structure clear, handling ease, and production cost is low, can extensively be used on the various camera of high, medium and low shelves, since simple to operate, do not waste film and be easy to be accepted by numerous cameramans.

The utility model is described in further detail below in conjunction with drawings and Examples:
