The closure in the removed and unused replacement part is then relaxed, which benefits further precise functioning and its service life.

On the other hand, single-lens reflex cameras to which the invention is directed in particular are generally of such a nature that a covering of the recording material by means of the folding mirror or an additional light flap is associated with the film transport and the opening of the shutter to be carried out on the camera body. When the camera is cocked, the shutter can be removed without any loss of recording material · Sin connected However, the closure itself is also initially tensioned. According to the invention, Sr is relaxed by the deflection But because a subsequent screwing will tighten the lock again, the units that are then joined are in place (Replacement part and camera body) again in the matching Operating state, while they have different settings separately from each other ^ which correspond to their own life *

These work with the camera-fixed bayonet läppe η 10 together to the exchange unit consisting of the shutter and lens to be attached to the camera body. A control ring 11 is rotatably mounted on the pipe socket 7. The control ring 11 carries one Coupling pin 12 through a segment-shaped recess of the flange 8 reaches through · If the interchangeable part is attached to the Kamexa body, the ring 11 also engages through a segment-shaped recess 14 of the camera housing 1 through into a bore 15 of the gear 4, which is the same as the Ring 11 is rotatable about the optical axis of the camera. At the lock 5 itself, 16 is the cocking lever and 17 is the trigger. The parts 18 and 19 are angled webs from the control ring 11, the closure members 16, 17 lie in their range of motion.

When you press the transport button 1a (film transport) the gear 3 rotates the wheel 4 in a sense that when looking at the Figures 2 and 3 correspond to the clockwise direction. The accompanying pin 12 takes the control ring 11 with it, so that its web 18 pushes the clamping lever 16 in front of it and cocks the shutter 5. It can also be connected to other controls on the lock e.g. adjusting the aperture blades to full opening and opening the shutter sectors.

Outside the control rotations described, the gear 4 of the camera body is immovable in the locked state. It can therefore not be moved from the interchangeable part 5-8.

To describe the influence of the bayonet connection 9, 10, it is assumed that the replaceable part of the camera body is removed.

Assembling bayonet combs of one part with bayonet gaps in the other part of the outstanding pin 12 of the control ring 11 protrudes into the bore 15 of the gear 4 of the tensioned combs meets and couples with this. The Anrenken of Auswechselteil3 for producing the bayonet connection with nan camera body takes place with respect to FIG. 3 entgegengesärzt clockwise. The pin 12 coupled to the stationary gear 4 holds the control ring 11 together with its webs 18 and 19 so that they rotate relative to the closure housing 5, with web 18 holding the closure lever 16, i.e. tensioning, and web 19 the shutter release without any effect temporarily depresses. When the bayonet connection is established, the parts assume the position shown in FIG. To deflect, the replacement part is turned back in the UHESIGER direction (Fig. 2), v / whether the tensioned Kainara state is to be assumed. The again fixed Zahnrsäc 4 of the camera body holds the control ring 11 of the rotated interchangeable part, so that, just like when the camera is released for a recording, the web 18 is removed from the locking lever 16 and the web 19 by overflowing the locking release 17 expires the shutter and relax runs!

Unlocking the interchangeable part is at least as large as the angle of rotation that the interacting members 11, 4 of the interchangeable part and the Kansera body based on the Renk axis as the axis of rotation to cock and release the lock - the sector slots 13 and 15 in the end walls are just as big the interchangeable part and the camera body in order to create sufficient clearance for the coupling pin 12. A smaller Renkwinkel additional translation elements in the -Tax gears-require ^ what its ease of movement, especially to trigger the spanking when taking pictures. Of the The attachment of coupling members 18, 19 and 12 on both sides of the control ring 11 also serves to simplify the control gear (To or away from) the interchangeable part against- run sensibly to the movement that the actuator to control, E.g. the locking lever 16, for the implementation of its function or the one subordinate to it (locking process) needed. As is known, the tensioning lever 16 is subject to the action of a spring which moves it into its relaxed position strives to pull back so that it always rests resiliently on the web 18, regardless of whether the closure itself is relaxed or tensioned. 9m to prevent the replacement part from being removed when the camera is relaxed and the recording material 2 is thus uncovered The locking member 25 is provided on the camera body, for example. It rests with its shaft 22 in a displaceable manner in a bearing block 23. Sine spring 24 endeavors to keep member 25 in notches on the circumference <3e3 to insert edge 3 of the replacement part.

Such a special safeguard can consist of a lock on the camera body which, depending on the removal of the interchangeable part from the camera body, locks the camera gear 4, 3 in the operating state assigned to it, in this case the opened camera gear against running off Locking slide can be provided, which is spring loaded against a surface of the coupled interchangeable part without exercising a locking function, but slides into the camera drive mechanism in a locking manner when the interchangeable part releases the locking slider when it is deflected or removed. The same lock, on which the Kaaerakbody then acts, can also be arranged on the interchangeable part in order to prevent its control ring 11 with the lugs 12, 18, '19 from rotating which would change the operating state of the removed interchangeable part.

To be used in conjunction with interchangeable lenses of various dimensions Central locks of various sizes for use to bring, are between their actuators 16, and the coupling pin '12, which in view of the ratios
