Photographic camera with a device for igniting ignitable flash lamps

The invention relates to a photographic camera with a
Closure and a device for igniting impact-ignitable
Flash lamps, whereby all parts can be actuated by a drive element that can be tensioned and released by the camera trigger
are and where the ignition device t in the absence of flash lamps. Drive member can be switched off.

If there are no flash lamps and the ignition device is switched off for this, the drive element does not experience any deceleration corresponding to the ignition pulse in proposed devices of this type, so that it runs against its end stop with great force and shaky shots with long exposure times can cause. This is to be avoided with the present invention.

To solve this problem for a camera, the
mentioned type suggested that depending on in the

Flash lamps installed or not installed in the camera alternatively dir igniter or a henim arrangement for the drive member can be coupled to this. According to an advantageous, simple embodiment, it is provided that alternately the ends of an ignition lever or an inhibiting lever in the drainage path of a pin or tab of the drive member are pivotable. It is advantageous here that a control lever is provided, the starting position of which is determined by a during insertion ■ member moved by BIitilampcii can be determined and through which the

alternating pivoting movement of the ignition lever and the inhibitor lever can be brought about, with both the ignition lever and the inhibitor lever being braced with the control lever via springs and with the levers interact with stops on the control lever.

The invention is explained in more detail using an exemplary embodiment.

Fig. 1 shows the arrangement in the absence of a flash lamp holder,

FIG. 2 shows the arrangement according to FIG. 1 with the flashing lamp carrier inserted.

In Fig. 1, a central member 1 of a still camera is in the cocked position held by camera shutter 2. Via a radial

Position held and pressed by the spring 4. A pawl 5 is rotatably mounted on the slinger 3. A lightning die socket 6 is rotatably mounted in a circuit board 7 in the camera. An ignition lever 8 is operated by the spring 9 with a control lever 10 held together. The control lever 10 holds a switching rod 12 upward by the spring 11. A flag 13 and a pawl lever 14 cooperate in a known manner with a finger 8a of the ignition lever. Incidentally, it is a well-known one Spaiuianordnuiig provided for the central link 1.

The mode of operation of the arrangement is as follows: If the camera release 2 is actuated, the spring 15 drives the central link 1 clockwise, with the pin Ib running past the nose 8b of the ignition lever 8 and the pin 3a resting against the radius section la so that the slinger 3 does not move. Only can lc at the corner of the pin 3 are incident and ^a spin member 3 to rotate under the action of the spring 4 in a clockwise direction. The pin 5a flings the sector 16 on the nose 16a in a known manner.

If a lightning cube 50 is inserted into the socket 6, it hits the pin Ib when the central link 1 runs off the ignition lever 8 on the nose 8b upwards, because via the switching rod 12 or

whose pin 12a and the control lever 10 of the ignition lever 8 upwards moved to scan the ignition wire and thus at the same time the nose 8b was pivoted into the drainage area of the pin Ib. If the central link 1 rests against the bolt in the expired position, the pin 1b has the nose 8b in front again.

Devices of this type have been proposed. There is a risk that, if the flash cube 50 is not inserted, the timing element 1 will hit the stop 20 with full force and thus result in blurring during long exposure times. This impact is due to the fact that the central glide is not hit by the actuation of the ignition lever 8 after it has been pivoted out of the way of the pin 1b. In order to avoid this impact, an _{escapement mechanism 5I 1} 52, 53 is provided according to the present invention, which in the present example consists of an armature lever 5I, armature 52 and spring 53, but

others just as well from a Henuiasse with pen or / known inhibiting means can exist. The armature lever 51 is coaxial about the axis 5 ^ mounted to the ignition lever 8 and has an end 51 b.

When the lightning cube 50 is not inserted, the armature lever 51 rests under the action of the spring 53 ^ in a stop 10a of the control lever 10, whereby due to the position of the control lever 10 and H _it pin 12a, the end 51b of the armature lever 51 instead of the

End 8a of the ignition lever 8 in the drainage path of the pin Ib of the central link 1 lies. During its course, after the lock has been actuated, the Z-central link 1 therefore encounters the escapement 51b, 51 »52, 53-r b «w * gt" "aieses under tension of the spring 53 and is slowed down, after it has fulfilled its functions.

When the lightning cube 50 is inserted, however, according to FIG. 2, da3 is End 8b of the ignition lever 8 in the drainage path of the pin Ib of the central link pivoted as already described. For this purpose, the pin IQa in the corresponding to an inserted Blitzvrfel 50 Position of the control lever 10 of the armature lever 51 pivoted into a position in which the end 51b of the armature lever 51 outside the Drainage path of the pin Ib is. After the central link 1 through the actuation of the ignition lever 8 is braked, it is now not braked by the inhibiting mechanism 51.

Of course, other exemplary embodiments, not shown in the figures for the sake of simplicity, are also possible. That's the way it is it is not imperative that the ignition lever 8 and the inhibiting lever 51 are mounted on the same axis are. The shapes of the levers can also differ. In particular, the central member 1 can have a different shape and a Take up another position in the Ka lera and, if necessary, the double exposure lock at the same time steer. In addition, the invention is also useful when, instead of a lightning cube 50, only a single one Flash lamp which can be ignited by impact can be inserted into the camera.
