Hairpin spring 47b, which is supported on a stationary pin, the angle lever 47 is loaded in the tube. At the era 47o of the angle lever 47 lies a flap 72a of a lever oil of the objectivehousing 2 described below. Line locking pawl 49 is mounted by means of its bore 50 on an unillustrated pin which is perpendicular to the camera body 1. It works together with the already mentioned locking edge 41 o and is actuated on its bent arm 49 a by the Mtneiimernaae 12 o of the slide 12. A needle spring 51 loads the pawl 49 counterclockwise.

At this point the function of the hitherto is expedient Kasaerageiriebes described according to FIGS. 2 to 4 to be explained before the description with reference to the remaining figures to be continued *

If the lever 3 is rotated counterclockwise from its rest position shown in Figure 1, the spur gears 10 and 11 rotate in the same direction and at the same angle via the driving connection 3a / 10 or 3a / 11. Here, the Mim \ xm is switched one image length further and the sliders 12 and 41 are moved from the position shown in FIG. 2 to the left into the position shown in FIG. 3 . The movement of the slide 12 results in the rotation of the fiitaels 14 in a counterclockwise direction. However, this rotation does not affect the shaft 16 because the design of the coupling halves 15

By rotating the Ritaeis 43, the lens shutter 2 is transferred from the rest state to the clamping state in the manner explained below, flg. 3 shows the camera gear in the clamping state. It can also be seen that the holder pin 3a has again assumed the rest position © shown in FIG. 2, because a return spring acting on the lever 3, which is not shown, has returned this lever to its rest position. Also shows Pig; 3 and also FIG. 4 that the rope 65a, which is working with the driver arm 24o of the scarf mechanism 24, of the objective linkage described below has left the driver arm, as a result of which the force of the compression spring 20 has become free. This enables the slide switch 24, which is under the force of the compression spring 20 via the parts 23 »21, 19 and 18, to assume its left end position so that the coupling halves 5, 15a come into engagement.

This movement is transmitted by means of the release rod 48 to the angle lever 47, which is rotated counterclockwise against the force of the hairpin spring 47b Tension spring 13 in © a © starting position aurtlokbefBrdört. Here, the egg shaft 14 and, via the engaged sawtooth coupling 15 / 15a, the well © 16 are rotated clockwise. The driver pin 25a of the Jtirarad 25, which is fixed on the shaft 16, passes under the pin 26a of the lever 26 after a correspondingly dimensioned path, so that the latter is pivoted upwards about a pivot point at 27. By means of the connection 26b / 28 the question? 29 iron mirror 30 is raised against the force of the clock spring 32 until it is completely removed from the beam path. The rotation of the spur gear 25 in a clockwise direction causes the pinion 33 to rotate and thus the head 39 to rotate counter to the clockwise direction. Here, the coil spring 35 is tensioned. The counterclockwise rotation of the shaft 39 causes both the previously open lens shutter to close as well as that of the lens shutter from the krb'EJtÖurohmesaer to the diameter that has been preselected by means of the Mnatellringea.

Kura before the end of its expiration, the slide 12 detects rait his driving nose 12c the Ana 49 a of the pawl 49, so

that the latter is removed from the path of the locking edge 410 of the slide 41. The sole lever 41 now moves to the right under the force of the tension spring 42, as a result of which the pinion 45 rotates with it the shaft 44 in a clockwise direction. The rotation of the shaft 44 in the clockwise direction triggers the ob ^ ectiwersole in a manner explained below. When the closure process has ended, in a manner also explained further below, the cable 65a of the lens soleplate is guided under spring force from the left to the driver arm 24c of the stop slide 24, whereby the switch slide valve moves from its left end position to FIGS. 3 and 4 into a right one.

The shift lever 18 fastened on the rod 19 takes the coupling half 15 with, whereby their engagement in the coupling half 15a is canceled. Hach the release of this coupling connection is now the force of the clock spring 35 freely, so that the pinion 33 and with it the shaft 39 is rotated clockwise. There, as beaclirioben above, the rotation of the skins 39 counter to the Clockwise to close the lens lock and the The result is that the rotation that has now taken place is anticlockwise the previous movements The lens closure and the lens diaphragm are reversed do.

The rotation of the ritual 35 is clockwise for one Anticlockwise rotation of a spur gear 25. Through this the pin 26a of the lever 26 is released again, bo that the clock spring 32 the carrier 29 of the mirror 30 aua the in Fig. 4 in the position shown in fig. 2 and 3 shown Location can aurüokftihren. The Kaaera transmission is now in the in depicted resting position auraok been guided.

The just described mode of operation of the Kaseragetriebea, Which will be referred to below is be-bonders to note}

a) The smooth clamping movement of the slides 12 and 41 influences the shaft 44 _f because of the design of the coupling 15/15 a _t, however, not the shaft 16 and the parts connected to it. The only consequence of this is that the mirror 30 and an opening device, which will be described later and which is coupled to the shaft 39, for the external socket and the lens diaphragm remain at rest during the clamping process. The observation of the recording object is the outer double-edged prism 5 »mirror 30. and camera lens existing camera lens is therefore possible both when the aid has expired and when the Kaaera gearbox is engaged.

b) The Hüoklauf of Sohiöber 12 and 41 has the effect that both shafts. 16 »44 are rotated, and gwar the

Shaft 16. Since, however, is earlier than the shaft 44 to the shaft 16, the mirror 30 and, as to be described later, an opening device for Objektivverachluß and lens aperture is coupled carried whose movements before ü & m triggering the Objektivversohluases, welohes controlled by the shaft 44 will.

c) Part of the force in the tensioned mainspring 13 stored iat, when the slide 12 returns to tension the coil springs 32 and 35 used. The force of the clock springs is released when the clutch 15 / 1i? A is disengaged, which in nooh 2U descriptive Y / eise of the almost expired Qbjective closure is effected.

The Relationship Between the Based on the Pig. 2 to 4 described IC camera gear and those essential for puncturing the camera Parts of the lens zoom lens 2 are shown in FIGS. 5 to 7 shown.

The push pawl 54 is connected to the crank 53 in an articulated manner and has a control edge 54a for cooperation with a stationary pin 55 and at its free end a mouth 54 "b. On the front end of the shaft 59 aitat Drehfeat a pinion 56 and meshes with a front end of the shutter housing 2a rotatable about the optical axis mounted actuating ring 57. This actuating ring has a tab 57a, which in the usual and therefore The lens that is not shown here is the fit 9 of the interchangeable lens takes hold of the movable ring of the lens diaphragm press u.

The aforementioned Yielle 44, like the shaft 39, is parallel to the optical axis from the camera body 1 into the objective « Shutter 2 guided, with SLA in one in the base plate 2b attached sleeve 58 is mounted. A pinion 59 is seated almost rotatably on the front end of the shaft 44. This pinion has, for purposes explained below, a driver 59a and meshes with one in the 7ersohluß around the optical axis rotatably mounted control ring 60. The 3 control ring 60 is counterclockwise by the force of a tension spring 61 loaded and has a squat 60a. A pawl 62 is provided for cooperation with the cam 60a, which are rotatably arranged on a bearing pin 63 fastened in the base plate and are supported by a hairpin spring 64 counterclockwise is loaded. The pawl 62

The shutter drive member 65 is arranged freely rotatably on the sleeve 53 already mentioned and is clockwise loaded by a Yerachlufi drive spring 66, which us the Wrap 58 wrapped and with its free 3nde in not shown Way is stationary ubgeatUtst. For cooperation both with the liitnehmerarm 24 c des described above Switch slide 24 as well as with desi driver 59a of the Hitaels 59, the shutter drive member 65 has a tab 65a.

In the closure leaf drive 67, the optical axis is rotatably mounted on the base plate 2b and has drive pins 67a which protrude through arched recesses 69 in the base plate. The driving pins 67a engage in the base 68a of the Yerachluss leaves 68, of which only one is shown for reasons of clarity. Since the Versohlußblät.ter are rotatably disposed on the stationary bearing pin 70 68, it follows that the rotation of the drive ring 67 is applying from that shown in FIGS. 5 and 6 illustrated position in the clockwise direction a similar rotation of the Versciilußblätter 68 and thus the closing of the Lichtdurohtrittsöffnung.

Ss can therefore be based on the detailed description this cooperation will be waived. The cooperation too between the control ring 60, the pawl 62 and the Shutter drive member 65 is known and detailed in FIGS Patent specifications Switzerland No. 230 156, USA Ko. 2 943 551 and France Ho. 1 124 838.

A two-armed lever 72 (Fig. 6) is mounted on a pin 71, which is fastened in the base plate 2b. It is loaded in a clockwise direction by a hairpin spring 73, so that its tab 72a, which protrudes through a slot in the base plate, is supported on the arm 47o of the finke fog 47. The lever 72 operates with the lobe 74 of a 3pQrrklinke otherwise not shown together, which locks in a known manner upon adjustment of the bezel 7 JClick ⁿ ß "and depressed Auslööeknopf 6 to the drive ring 67 at open Yerechluß.

At the end of the movement processes just described, the drive ring 67 is in the starting position for the later taking place exposure process. At the same time, the mouth 54b leaves the Scfaubklinke 54, the control edge 54a of which on the stationary Pin 55 hits pin 67bj thereby making the connection between the shaft 39 and the drive ring 67 released and the drive ring can be carried out later by the closure drive member during the spilling process 65 be moved «iSbenfalla as a result of the Rotation of the shaft 39 has aioh the ritael 56 in the same sense and thus the actuating ring 57 in the. turned in the opposite direction, which leads to familiar and therefore not further here illustrative way the lens diaphragm to close to the preset value was initiated. The camera is now ready for the exposure process prepared} it is therefore only necessary to trigger the expiry of the objective solenoid, which, as already mentioned, takes place by lifting the pawl 62.

The shaft 44 2 to 6 in the Uhxaeigersinn and consequently the St «uerring 60 rotated counter to the Jhrsseiger direction. Here the tension spring 42 is supported by the force of the tension spring 61. When the control ring 60 rotates, the

Cam 60a on the one with it. working together en arm of the pawl 62, so that the latter is rotated clockwise according to FIGS. 5 and 6 and thereby the locking of the shutter drive member 65 is repealed.

The Verachlußantantrieborgan 65 then rotates under the Force of the verso drive spring 66 clockwise (according to Pig. 5 and 6) and thus causes a rotation of the drive ring 67 initially counterclockwise and then clockwise. Through this the shutter blades '68 are also initially pivoted counterclockwise about their bearing pin 70 until they have completely released the light passage opening, and then in the opposite direction until the Lioht passage opening is closed again 2 returned. "The interaction of the shutter drive member 65 with the drive ring 67 is known and in the patents Sohweie Ko. 311 246, USA JFo. 2,785,612 and France No. 1 075 891 is described in detail, so that it will not be discussed in more detail here. Do the now finished Exposure process requires that the closure sheets 68 and the lamellas of the objective diaphragm, not shown here, are removed again from the beam path, while the mirror 30 is to be pivoted into the beam path ©. This is done in the manner described below »

Immediately before the end of the movement of the shutter drive member 65 strikes its tab 65a on the driver arm 24c of the slide switch 24, which latter is in the

By the kj & ft of the Shutter drive spring 66 is the Sohaltsohieber 24 in the shifted position shown in Fig. 2 and thereby canceled the engagement of the coupling part θ 15 and 15a. The one in the ¥ / iökelfeder 35 stored © force is thereby released, so that the pinion 33 about the? / elle 59 according to FIGS. 2 to 5 in a clockwise direction, 7 are rotated counterclockwise according to FIG. As a result, the spur gear 25 rotates in the opposite direction Clockwise and its moving pin 25a gives pin 26a of the lever 26 freely The vtiokelfedar 32 Can then the Carrier 29 of mirror 30 from the position according to Pig. 4 in the Location according to the Pig. 2 and 3 lead back.

The rotation of the wells 39 according to Pig. 7 counterclockwise leads to such a rotation of the crank 53 »thereby is the pusher with its control edge 54a on the The pin 55 is guided along so that its mouth 54b encompasses the pin 67b of the drive ring 67. Maohdem the connection between the push pawl 54 and the pin 67b is restored, the further rotation of the? / elle 39 »causes the Pin 67b according to FIG. 7 from a left to its right end position is shifted, waa corresponds to a rotation of the drive ring 67 according to FIG. 7 is ühisseigereinn. Since the direction of rotation of the Locking blades 68 is the same as that of the drive ring, it results that the previously closed Liehtdurohrittsaufnahme is released again.

The spur gear 80 is seated in a rotationally fixed manner on a shaft 81 which runs parallel to the optical axis and is axially immovable in the Kaiaerakörpar 1 in a manner not shown. Another spur gear 82, which is also non-rotatably seated on the shaft 81, meshes with the already described pinion 43. The embodiment according to FIG. However, since the shaft 44 is rigidly coupled to the slide 12 in the example according to FIG. This requires a certain overall transmission from the slide 12 to the shaft 44.
