Photographic camera

The invention relates to a photographic camera with a lens., A shutter and a film room through a lid can be closed »

Cameras of this type in which the film is inserted by hand must, are already "known. To the inexperienced amateur that To facilitate film loading, cameras have also been used for Developed cassettes in which a cassette only has to be inserted and the rear cover must be closed. But also Here the user still has to insert a cassette into the camera himself - and after exposing the film the Remove the camera again. If you accidentally open the camera before the entire film is exposed, you can take some pictures Get light and become unusable. This disadvantage is used with the so-called "disposable cameras" in which the film

PF 64i / MP 1107

during assembly, * is avoided because the camera and film are given for development and destroyed when the film is removed in the darkroom «Beim Destroying the camera can scratch the film. In addition, such a "disposable camera" never reusable.

To avoid these disadvantages of the known cameras, it is proposed according to the invention that the cover is connected to the camera housing by connecting links that can only be detached with a special tool and to save film removal «In addition, a user cannot render the film unusable by accidentally opening the rear cover«, The user acquires the camera and film and gives the film and the camera for development »In the darkroom, the cover can then be removed with a special tool * without that the film may suffer damage and without the camera would be destroyed _e whether then made up the camera again with film and as it were included on loan with the film or whether they will be thrown away after one use ,, it's just a matter of rationalization "

Further advantages and details of the invention are based on explained in more detail by drawings »It show

1 shows a camera according to the invention from behind with the rear cover removed,

FIG _e 2 is a plan view of the camera according to Figo Λ ₉ partially in section according to the section line II - II.

In the figures, the pin of a spring bolt is denoted by 1. The spring bolt has a conical cone head o The cone head 3 and the lower part of the pin 1 are slotted. A total of four spring latches of this type are attached to one of the parts to be connected Q _s 9 _S, namely preferably to the camera cover 8, and are pressed through the opposing surfaces 10 when the camera 9 and cover 8 are connected compressed so that the radius of its largest circumference is still smaller than the radius of the opening released by the opposing surfaces 10. After the cone head 3 has slid through this opening released by the opposing surfaces 10, the slot 4 spreads open again, so that each cone head 3 is supported with a shoulder 19 on the mating surfaces 10 and connects the parts 8, 9.

A known manner is required to resolve this connection a release device ο The mating surfaces 10 and the conical surfaces 3 from the front of the camera Holes 15 »which are in the extension of the openings *

accessible »If this release device is now pushed through the bores 15 onto the cone heads J5, each cone head 3> - is compressed _o The cone of the release device exerts a force on the cone head perpendicular to the slot 4 and thereby presses the cone head J5 together in such a way that that the radius of the largest circumference of the cone head 5 is smaller than the radius of the opening released by the opposing surfaces. Therefore, the conical head J5 can now slide through this opening past the opposing surfaces 10, whereby the connection between cover 8 and camera 9 is released again "The holes 15 as will be stocked with at film camera by a plate ίβabgedeckt _s z, pasted. To remove the film, this circuit board, which could also be screwed on, is * removed * so that the holes 15 for the tool are exposed «,

To make opening the camera easier in the darkroom, can in a known manner on a plate at the distances provided on the camera and in the correct Number release devices attached so that the camera front only needs to be printed against this plate in order to simultaneously close all connection points on the camera solve.

Of course, the invention is not restricted to the exemplary embodiment shown. So could take the place of the

Spring bolt 1 also connect any other known connection that can be detached using special tools »The holes 15 * which too the opposing surfaces 10 comprise ^ are naturally separated from Film space in the camera body 9 arranged. So that through it no light can penetrate the film «.

The camera according to the invention has the advantage that the user is completely exempted from inserting and removing pillows and receives the film inserted into the camera and along with the Camera to develop there. However, when the film is removed for development, the camera is not destroyed, so it is new can be made up with film and also no damage of the film can occur when opening the camera »

Claims (4)

PP 641 / MP 1107 claims 1. Photographic camera with a lens, a shutter and a film space which can be closed by a cover, characterized in that the cover (8) with. to the Camera housing (9) is connected by connecting links (1, 3) that can only be detached with a special tool « 2. Camera according to claim 1, characterized in that the Connecting links (1) are snap-fastener-like spring latches which are attached to one of the parts to be connected and on which mating surfaces (1O) of the other of the to be connected Attack parts and which wedge surfaces become effective when connecting or disconnecting the parts to be connected (3), which in a well-known manner as hook-shaped cone heads (3) formed with a slot (4) are. 3. Camera according to one of the preceding claims, characterized characterized in that when the cover (8) is locked, the cone heads (3) through bores (15) in which the mating surfaces (10) supporting part (9) are accessible with a special tool. PP 64i / MP 1107 4. Camera * as claimed in claim J5, that the bores (15) by a plug-in or screw-aufkleb- _s Prontplatte (16) can be covered, " 5 »camera according to claim 5 or 4, 'characterized _s that the bores (15) separated from the film chamber holes in the camera housing (9) * ββ camera and special tools for this according to one of the preceding claims, characterized in that the special tool has a cone compressing the cone head (j5), the radius of the smallest The scope of this cone is only slightly larger than the radius of the smallest circumference of the cone head (5) and the radius of the largest circumference of the cone are smaller is than the radius of the opposite surface ('1O) 'released mouth.
