"Power image capture device"

The invention relates to a photo recording device an interchangeable lens, a diaphragm device and one associated with the same and operating according to the exposure meter Hegel device.

Ea is the object of the invention, the Sinstellanordnung a Such Lichtbildaufnahm.egera.tes with simple structural elements to design in such a way that an automatic aperture RegeIeinricntung can be used jointly by all lenses. In this way, the diaphragm of everyone should just be inserted Interchangeable lens through the common device-side control device be adjustable, regardless of whether it is a single lens reflex camera or another type of camera.

This object is achieved according to the invention in that the Aperture control device is arranged in the device and has a Hegel member, many in preferably the aperture size 13 t opening corresponding limit setting is adjustable and when returning from this limit position through a from Light meter controlled or formed locking member

is stopped because the diaphragm device in the interchangeable lens is installed and has a diaphragm control member, which is also counter to a return spring in the direction of Largest aperture is movable and one from the interchangeable lens mount has outstanding driver, and that a clamping member is also provided in the device, wherein the llegel member via projections on the one hand with the device-side Tendon and on the other hand with the interchangeable lens side Driver can be brought into driving connection by the diaphragm control element. In the preferred embodiment of the ".S rf in development, the aperture control element, the regulating element and the tensioning element are designed as rings coaxial to the optical axis, being the hit taker on the aperture control as a radially outwardly directed and axially parallel at its end .. cranked arm is formed, while the one with the control ring movable gate projections as axially extending tabs, pins or the like. are trained.

In the description below are some exemplary embodiments the invention explained. Show it;

Figure 4 shows a modified detail from Pig. 1.

Δη of the front wall of a not shown photographisohen The camera is attached to the housing 10 of a shutter equipped with a holder 10 ′, in which the sectors 13 are housed, the opening and closing movement controlled by a 3ektorenantriebsringf212 in a known manner are.

"The shutter clamping shaft 30, which can be coupled, for example, to the transport gear of the camera 1, drives the clamping ring 80 mounted on the back of the shutter 10 via the pinion 30 '(Mg the stop notches 84b ¹ wearüen Hing 84 is in operative connection, so that the same is brought into the limit position for maximum aperture during the economy process.

After the camera has been triggered, one controlled by the exposure meter and working together with the stop detents 84 ' The pawl of the ring 84 is stopped when the return movement takes place under the action of its leather 84b from the limit position and the aperture thereby in one of the respective exposure value brought corresponding operating position. The diaphragm blades built into the interchangeable lens are not shown. The interchangeable lens has a two-part mount 200a, 200b, with an aperture control 202 between the two 3?

share is rotatably mounted and loaded by a spring 202a, which pull it in .Direction on the small aperture seeks. The! Socket 200a has bayonet slots 200o, the in a known manner with corresponding Ba j one ttvor jumps 204a one with the lock housing 10 or with the camera connected stationary bayonet ring 204 cooperate, iiin cover ring 204b and an intermediate ring 40 are with the fixed bayonet ring 204 connected. The hand part rings 22 and 96 for the exposure time and aperture are rotatably mounted between the parts 204b and 40. aside from that an intermediate ring 122 is rotatable between the parts 204 and 204b stored, the arm 122b through a slot of the ring 204b forward into the path of movement of an arm 202b of the interchangeable lens-side diaphragm control ring 202 protrudes. Of the Intermediate ring 122 and stop ring 84 are provided with the same teeth on the circumference and one in the closure housing 10 mounted "cell 120 with toothed pinions 120a, 120b with one another tied together.

The arm 202b comes into engagement when the / achsel lens is placed in the mounting bracket and when it is then adjusted, ie 1) 3 ± a counterclockwise rotating movement of the lens mount 200 (seen in the direction of the arrow A) with the arm 122b and the diaphragm control 202 is stopped under tension of its spring 202a by the here immovable arm 122b, so that the interchangeable lens side diaphragm when the

The interchangeable lens is brought into an ο division corresponding to the automatic aperture setting on the camera j ζ. For example, when the V / change lens is in the automatic clamping position, the diaphragm is transferred from the smallest opening to the largest opening, if, on the other hand, the manual adjusting ring 96 is set for optional diaphragm setting, then when the interchangeable lens is adjusted, the arm 202b is moved by the stop 96b in stopped at the selected aperture position.

The automatic diaphragm requires that in the present embodiment the jiinrenkbev / egung of the i / echselob j ective counter-clockwise (left bending) takes place in. contrast to the real movement usual with interchangeable lenses. If necessary, however, a rightward movement can be made achieve without difficulty.

Palis the described automatic shutter in connection with a single-lens reflex camera is to be used, as long as the clamping shaft of the shutter is one in IPig. 2 and FIG. 3 assign shown device for opening and closing the locking sectors in the simplest possible way.

The pinion 30 'and the the running movement of the rings 80, 64 in cooperation with the armature 104b inhibiting climbing wheel 104a are firmly connected with the interposition of an actuating disk 206 with a hub 208 to form a built-in unit, e.g. B.

riveted. The hub 208 is in a sleeve 10a of the lock housing 10 rotatably mounted and positively engages around the flattened end of the Sρarmwelle 30, so that the parts 30 ', 206 and 104a rotate together with the opening shaft. An opening pawl 210 is loosely rotatably mounted around the sleeve 10a, those with their arms 210a, 210b with a pin 212a of the sector drive ring 212 cooperates. An IPeder 214 engages around the sleeve 10a and is supported with one end 214a on the tab 210 'of the pawl 210, while the other End 214b rests on the other tab 210 ″ of the pawl 210. An arm 206a of the actuating disk 206 lies in the path of movement of the peder end 214b, so that it opposes the same clockwise (Pig. 3). The opening pawl 210 itself is equipped with a return spring 210c.

When cocking the shutter and the automatic iris comes when the actuating disk 206 is rotated counterclockwise, the arm 206a of the same engages with the peder end 214b, whereby the opening pawl 210 is rotated counterclockwise and the pin 212a with the sector drive ring 212 in the same direction. As a result, the closure sectors 13 are opened for interposing. After triggering, the lines 30, 206 and 210 run in opposite direction, whereby the sectors are closed again before the actual exposure.

The merging of parts 30 ', 206, 104a and 208 into one

.Sinneit has the advantage of a space-saving assembly facilitating arrangement. 30 The isolation circuit of spring 214 between the actuating disk 206 and the opening pawl 210 brings the further advantage of an interim releasability of the frictional engagement of the arms 210 ″ and 214b during the opening process, so that, for example, damage to the sectors and their storage by actuating the opening device can be avoided in the unsuitable operating state of the lock.

In J? Y. 4 shows a design "which closely follows the Embodiment according to Pig. 1 leans against. The timing ring 20 is not connected here to the time setting ring 22, which can be rotated as required by hand, but can be rotated freely and through loads the spring 110 which engages his arm 20m with the arm 122b of the ring 122 holds. This is done at the automatic aperture setting is also an unavoidable time setting.

The arm 20m of the timing ring 20 can also be with the stop 114a of the switching ring 114 brought into cooperation if any manual time setting is desired.

In the arrangement according to the invention, all are adjustable elements and the clamping device is assigned to the lock on the chamber side and combined here to form an assembly group. This group

thus forms a setting arrangement of the device common to all interchangeable objects, an? / elolie. the aperture mechanisms of the respective '' / echselob j ective can be connected when changing the object. Me operating simplicity and clarity are guaranteed with simultaneous puncture safety.
